It is understood that, recently, the ecological environment Department of Henan Province issued the "Henan electricity in 2019 non-standard governance program industry" and six special programs, mainly to further promote the campaign of air pollution control, to ensure that the province's ambient air quality continues to improve. Meanwhile, the "plan" also made clear this year Henan Province industrial air pollution control in key tasks.

The province meet the conditions of steel, coke, cement, carbon (including graphite), flat glass (including electronic glass), aluminum and other six major industries and enterprises, the requirements before the end of this year to complete the mentioned standard treatment, the required limits for reducing pollutant emissions. Carry closed down or banned brick kiln, lime kiln, tunnel kiln, firing kiln and a variety of smelting furnace, roaster and so on nine categories of Kiln, upgrading, restructuring and integration work. Before the end of October this year, all kinds of industrial furnaces to achieve discharge standards.

Before the end of June this year, the province's petrochemical, oil refining, industrial coating, packaging, printing, chemicals, pharmaceuticals and other industrial enterprises, the full completion of volatile organic compounds pollution control; before the end of August, the province's petrochemical, oil refining companies to complete volatile organic compounds depth governance and leak detection and repair of governance; before the end of December, the provincial cities of built-up areas phasing out the open dry-cleaning machine.

Before the end of October this year, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province completed 35 steam tons / h coal-fired boilers and the removal or clean energy transformation, provincial cities and county (city) district built 4 tons of steam and above gas-fired boiler, fuel (including alcohol-based fuel) boiler low nitrogen transformation complete, the provincial municipality to build a biomass boiler area (including biomass power plants) completed the first ultra-low emissions transformation. Before the end of June this year, the completion of the provincial cities to build coal-fired facilities Chaigai all industrial areas.

Boiler feed water preparation device preparing process advantages and disadvantages current power boiler feed water system ultrapure water substantially above three processes, rest of the process are carried out with different combinations of the three basic process on the basis of the above derived. Their disadvantages are now listed in the following: 1, a first ion exchange resin is advantageous in that low initial investment, space occupied, but the disadvantage is the need for frequent regeneration of ions, pH-consuming, but also for the environment certain destructive. 2, the second stage reverse osmosis equipment, which is characterized by the early administration level attained manner using ion exchange resin is higher, but without resin regeneration. The disadvantage is that the original film is related to be cleaned or replaced regularly, the water quality is not too high, relatively speaking, most can do about 1us / cm. 3, the third reverse osmosis for pre-matched electro-deionization (EDI) apparatus, which is ultra-pure water system to take the preparation of ultrapure water most economical and environmentally friendly, it does not require regeneration with acid continuous Preparation of ultrapure water, no environmentally destructive. The disadvantage is that the initial investment is relatively above two methods are too expensive. High-pressure boiler feed water treatment equipment for industrial and mining enterprises and medium-sized thermal power plant and boiler feed water treatment. The world's most advanced reverse osmosis membrane element, pressure vessels and other equipment, supported by reasonable and have a pre-processing and post-processing equipment, can produce boiler feed water in line with national or industry standards (GB1576-79, DL / T561-95) super pure water. In the membrane treatment system, used typically ultrafiltration pretreatment 1mm diameter hollow fiber, to remove suspended solids and colloids in raw water, the biggest problem is the pretreatment as UF membrane fouling and membrane clogging for this often provided at the front pre-filter, to remove large particle suspension was pre-filtered before flocculants, such as PAC (poly acrylic acid) can improve the filtration quality, and reduce the membrane resistance. The amount of dissolved oxygen to the boiler feed water system of the plant required for the general requirements 0.3mg / L or less, for degassing membrane should be operated at a vacuum of less than 5.33Kpa (40TORR) a. IPC programmable control system control, automatic start and stop, dosing and flushing, automatic monitoring of various operating parameters, for production management.

Use local steam boiler steam boiler plant equipment when they should beware of using should be very broad, stable operation even if the goods, work safety. But it does not mean that you can easily use. Now we give you a detailed look at some of the content when using the steam boiler equipment should beware of. The first, former boiler startup carefully examine before steam boiler plant boiler startup identification process is quite critical, we should examine the site there are many, like the fuel gas pressure is not reasonable, blocking the flue gas duct is not already open, the vacuum pump water is not a routine, etc. ....... Only ensure that equipment before conventional boiler startup, ensure the security of gas steam boiler safety work. Also, use should be used during downtime is quite Yan Shen during the shutdown process, turn a small fire to fire first, and then slowly the fire, burning closed valve. The contents of the safe use of gas steam boiler which should have these, and if you can pay more attention to the content in use, I think it can be fairly safe use of gas steam boiler, avoid places where improper use form occurs.

Vacuum hot water boiler how much you know? "A" 1. What is a condensing vacuum hot water boiler seller? A: The so-called vacuum hot water boiler, also known as phase-change vacuum hot water boiler. Refers to normal operation when the internal pressure below atmospheric pressure boiler medium, by heating the cold phase change heat boiler embodiment. (Internal vacuum-tight vacuum hot water boiler body, the heat medium water pressurized combustion, the generated steam heat exchanger for soft drinks, high thermal efficiency, the heat medium water at the factory in disposable infusion process, without replenishment operation. Vacuum hot water boiler unique design, form a safe, stable, etc.) 2. composition principle structure of the vacuum hot water boiler? A: vacuum hot water boiler furnace divided into two parts; the upper half portion of a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating flowing through the heat exchanger Recycled water. The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in the body with a closed circulation heating evaporation == == == heat medium condensed water, condensed water without added thus, no danger of burning air. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest. 3. What is a vacuum? A: The vacuum does not mean absolute pressure is zero, as long as the external pressure is lower than, for example, can be called a vacuum: a vacuum when the pot boiler shell is commissioning a vacuum state, and maintain -375pxHg - between 76mmHg.. 4. What is the degree of vacuum? A: refers to the degree of vacuum in the gas lean degree of vacuum in the book, usually with a low degree of vacuum and high vacuum to FIG. High degree of vacuum represents a good degree of vacuum means, a low vacuum degree difference represents the degree of vacuum means. Vacuum degree is lower than the actual value of the pressure of the system shows the atmospheric pressure value, i.e., the degree of vacuum = atmospheric pressure - absolute pressure. Vacuum of international standard units: Pa (Pa). Why The vacuum heating medium water heated hot water boiler in a vacuum state? A: water at different pressures, different boiling temperature which, at one atmosphere pressure (0.1Mpa), the boiling temperature of water is 100 deg.] C, and under a pressure 0.8Kpa the boiling temperature of the water was 4 ℃. Vacuum hot water boiler is operating within a pressure range of vacuum degree of 2.67Kpa ~ 66.6Kpa corresponding saturation temperature is 15 ℃ ~ 85 ℃. Thus, in a vacuum state, the heat medium is easily Boiling water. 6. origin vacuum hot water boiler? A: The basic principles of vacuum hot water boiler was born in 1972, Zurich University. In 1975 the Japanese company TAKUMA Based on this principle has developed a vacuum hot water boiler and patented invention, then gradually popularized throughout the world, this technology has been developed and the development of Korean companies have emerged TAKUMA Korea, China in the late 1980s Some manufacturers have developed vacuum hot water boiler, but due to technical problems, mainly due to gas generated immiscible declining degree of vacuum problems can not be solved electrochemical reaction occurs boiler water and vacuum seal of iron, has not been promoted . 1990s South Korea's manufacturing enterprises to enter the Chinese market relatively late in 2003 about the domestic boiler manufacturers began producing vacuum boilers.
