Smoke dust removal heat exchanger

Abstract

The invention discloses a smoke dust removal heat exchanger, which comprises a heat exchanger body, a smoke passage, a water flow passage and an ultrasonic dust removal device, wherein the ultrasonic dust removal device comprises an electric dust removal machine box and an ultrasonic dust remover, the ultrasonic dust remover is arranged in the electric dust removal machine box, a plurality of electrode plates, a plurality of dust collection nets, an air inlet, a high voltage power source and a rectifier are arranged in the electric dust removal machine box, multiple electrode plates are arranged at an inlet part near the air inlet, are parallelly arranged, and are arranged along the air flow direction of the air inlet, the dust collection nets are respectively arranged at the two side surfaces of each electrode plate, the air inlet is in a funnel shape with large opening diameter and large pipe diameter, high voltage power generated by the high voltage power source is rectified by the rectifier, and then is outputted to each electrode plate to supply power for the corresponding electrode plate, and the rectifier is connected with the ultrasonic dust removal device. The smoke dust removal heat exchanger has the advantages that the dust removal effect is good, the maintenance is convenient, and the labor is saved.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a flue gas dust removal heat exchanger. Background technique [0002] Plate heat exchanger is a kind of heat exchange equipment with high heat transfer efficiency, compact and light structure, large heat exchange area per unit volume and long service life. However, under abnormal circumstances, the heat exchanger is filled with stagnant water but the fire is still burning continuously. The water in the sheet at the first contact with the high-temperature flue gas will be vaporized, and the sheet at the first contact with the high-temperature flue gas will be vaporized. The temperature will rise sharply, and the temperature will continue to rise, which will destroy the connection mode between the heat exchanger plate groups. At this time, the safety protection device operates to close the gas valve, and water will flow out from the defect, causing heavy losses. In order to overcome the above de...

However, under abnormal circumstances, the heat exchanger is filled with stagnant water but the fire is still burning continuously. The water in the sheet at the first contact with the high-temperature flue gas will be vaporized, and the sheet at the first contact with the high-temperature flue gas will be vaporized. The temperature will rise sharply, and the temperature will continue to rise, which will destroy the connection mode between the heat exchanger plate groups. At this time, the safety protection device operates to close the gas valve, and water will flow out from the defect, causing heavy losses. In order to overcome the above defects, A plate heat exchanger for gas water heaters and gas heating water heaters has been developed. At present, a plate heat exchanger with a patent number of CN201420178095 has been disclosed in China. This design has solved some problems, but there are still other problems, such as smoke The air contains a lot of dust, and the heat exchanger body is difficult to disassemble. After a long time of use, the pipe is full of dust, which is difficult to clean and very inconvenient
