What are the methods to reduce pollution mill 1, check for leakage protection and maintenance of: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, repeated use of steam condensate: Textile mills require large amounts of saturated water vapor in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, the piping, valves and heat insulated flange experience pipes, valves and flanges waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery from the boiler chimney at a temperature of 360 ℃ smoking, sometimes discharged directly into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of textile machines Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.
4 tons steam boiler fast boiler's Henan small series with you briefly quick 4 tons a steam boiler. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of a steam boiler. He said first boiler say "pot." This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessel, the safety device is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used.
