An energy-storage thermal shock wave soot blowing method and its device

Abstract

The invention discloses an energy-storage-type heating power shock wave soot blowing method and device. The energy-storage-type heating power shock wave soot blowing device comprises a pulse wave spraying opening (1), an energy storage cavity (2) and a quick release device. The energy storage cavity (2) is filled with saturated water or saturated steam or superheated steam generated by a boiler through a conveying pipeline. The energy storage cavity (2) is installed inside the quick release device and connected with the pulse wave spraying opening (1). A second control valve (12) is arranged on the conveying pipeline through which the energy storage cavity (2) is filled with the saturated water or saturated steam or superheated steam. According to the energy-storage-type heating power shock wave soot blowing method and device, the existing saturated water or saturated steam or superheated steam of the boiler is directly utilized as an energy medium for generating shock waves, materials are conveniently taken, the cost is low, then the aim of quickly releasing the high-temperature and high-pressure saturated water or saturated steam or superheated steam inside the energy storage cavity is achieved by the adoption of a piston-type energy storage device and the utilization of the piston structure and the quick movement principle, and the soot blowing cost is quite low.

Description

technical field [0001] The invention relates to a cleaning method and device for heating surfaces of thermal power plant boilers, industrial boilers, waste heat recovery boilers, biomass boilers, etc., in particular to an energy storage thermal shock wave soot blowing method and device. Background technique [0002] The cleaning of the heating surfaces of thermal power plant boilers, industrial boilers, waste heat recovery boilers, biomass boilers, etc. is generally done with three types of sootblowers: continuous steam sootblower, sonic sootblower and acetylene explosion shock wave sootblower. accomplish. Among them, the continuous steam soot blower has the advantages of better soot blowing effect, simple structure and principle, but the disadvantages are high maintenance, mechanical jamming, high energy consumption, and a large amount of steam consumption. For the heating surface close to the nozzle, The blowing damage is relatively serious and the working distance is lim...
