Mixed ignition device for shock wave dust cleaning system

Abstract

The invention relates to the technical field of boiler dust cleaning equipment, in particular to a mixed ignition device for a shock wave dust cleaning system. The shock wave dust cleaning system comprises a dust cleaning control device, an air source supplying device and a plurality of shock wave generating devices, wherein the air source supply device comprises a first fuel gas pipeline, a firstair pipeline and a first wiring terminal box; the mixed ignition device comprises a second fuel gas pipeline, a second air pipeline, a mixing tank, n mixed gas pipelines, a second wiring terminal box, an ignition control box and an ignition head, wherein the mixed gas outlet of the mixing tank is connected with the n mixed gas pipelines, and a first manual valve and a normally-open electric control valve are sequentially arranged on each mixed gas pipeline; and the mixed gas pipelines are connected with the shock wave generating devices in a one-to-one correspondence mode. The gas shock wavedust cleaning system solves the problem that an existing gas shock wave dust cleaning system has the serious equipment corrosion in the use of corrosive flue gas boilers such as waste incineration andthe like, and has the advantages of being complex in configuration structure, high in operation failure rate, low in operation efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of boiler dust removal equipment, in particular to a hybrid ignition device used in a shock wave dust removal system. Background technique [0002] The shock wave ash cleaner is an important auxiliary equipment for various types of waste heat boilers, waste incineration boilers and power plant boilers. It plays a vital role in improving the heat exchange efficiency of each heating surface of the boiler, that is, increasing the output of the boiler. Shock wave soot cleaners include air shock wave soot cleaner and gas shock wave soot blower, among which the gas shock wave soot cleaner has the advantages of low operating cost, large cleaning energy and wide application range. Wave ash cleaner is the main choice equipment in the field of boiler ash removal at present. However, there are serious defects and deficiencies in the existing gas-fired shock wave ash cleaner, especially in the ash removal of boilers wi...
