Problems solved by technology

Not only does it cause a sharp drop in heat exchange efficiency (due to the extremely poor thermal conductivity of scale, the thermal efficiency decreases by about 8% for every 1mm thicker scale), but it also increases the power consumption of the circulating water pump. Due to partial blockage, the flow cross-sectional area becomes smaller and the resistance increases. Large, in the past, manual cleaning required dismantling the entire plate heat exchanger and using a high-pressure water gun to wash and clean it, which not only consumes a lot of manpower and material resources, takes a long time to clean, but also shortens the service life of the plates and rubber pads of the plate heat exchanger

Abstract

The invention discloses a steam pulse washing device. The steam pulse washing device comprises a first washing device body, a second washing device body and a plate heat exchanger; the first washing device body is connected with the plate heat exchanger; the plate heat exchanger is connected with the second washing device body; and a flushing pipe is connected between the first washing device bodyand the second washing device body. The invention further provides a washing method of the steam pulse washing device. Limescale and impurities adhering to a heat exchange plate can be removed in time under the condition of not dismounting the plate heat exchanger, the circulating heat efficiency of a heat exchange unit is improved, and the blocking removal cost is reduced.

Description

technical field [0001] The invention relates to a cleaning device and a cleaning method, in particular to a water vapor pulse cleaning device and a cleaning method. Background technique [0002] The plate heat exchanger is the main heat exchange equipment of the heating network heat exchange station of the thermal power company, and its heat exchange efficiency will directly affect the heat supply quality. During the operation of the plate heat exchanger, due to improper operation of the water treatment equipment and poor water quality control, circulating water that does not meet the water quality standards will be injected into the heat exchanger, and scale and slime will be generated. If the flow rate is reduced, it will be deposited on the heating surface to form a precipitate. Not only does it cause a sharp drop in heat exchange efficiency (due to the extremely poor thermal conductivity of scale, the thermal efficiency decreases by about 8% for every 1mm thicker scale)...
