Automatic impulse type washing device of heat exchanger
2013
The utility model relates to an automatic impulse type washing device of a heat exchanger. The automatic impulse type washing device comprises the heat exchanger and a controller, the two sides of the heat exchanger are respectively provided with an air side differential pressure sensor, a washing mechanism is arranged nearby the heat exchanger and comprises a water spraying tube, more than one nozzle is arranged in the water spraying tube, an outlet of the nozzle faces the air facing side or the air outlet side of the heat exchanger, and the air side differential pressure sensors are electrically connected with the controller for controlling whether water is discharged from the nozzle or not. The water spraying tube is connected with a water tank, a waterway solenoid valve and a water side pressure switch are further arranged on the water spraying tube and arranged between the water tank and the nozzle, and the controller is respectively connected with the waterway solenoid valve and the water side pressure switch electrically. A water supplement tube is arranged on the water tank, a booster pump is arranged on the water supplement tube, an impulse switch is arranged on the controller, and the heat exchanger is a finned heat exchanger. The automatic impulse type washing device has the advantages of being simple and reasonable in structure, flexible in operation, good in washing effect and low in energy consumption.
