Problems solved by technology

[0004] 1. The cleaning range of the equipment is limited, and there are many dead ends for cleaning: the existing gas shock wave cleaning system releases the shock wave energy through the nozzle of the fixed shock wave generating tank to the heating surface of the boiler within the range of action. For dust cleaning, since the shock wave cleaning energy is basically fixed and rapidly decays within the scope of action, and the shock wave is cleaned with a cleaning surface not greater than 90 degrees, resulting in large cleaning dead angles on both sides of the spout. The effective range of dust removal is greatly restricted, and the number of dust removal points is limited, and the second is that increasing the number will greatly increase the production cost. Therefore, market competitiveness and economic benefits are greatly affected
[0005] 2. The failure rate of equipment operation is high: the existing gas shock wave cleaning system has a complicated configuration structure
There are more failure points, so the failure rate is higher

Embodiment 1

[0029] figure 1 It is a schematic structural diagram of a mobile gas shock wave cleaning gun in an embodiment of the present invention. Such as figure 1 As shown, the cleaning gun includes:

[0030] Ignition control box 1, described ignition control box 1 specifically comprises:

[0031] Electrical control device 115;

[0032] Further, the electrical control device 115 includes an air switch, a push button switch, a time relay, an igniter 116, an ignition wire, a control cable, and electrical components, wherein the igniter 116 is connected with the hybrid ignition through the ignition wire. The ignition head 114 of the device 113 is connected.

[0033] Further, four universal joint steering wheels are arranged at the bottom of the ignition control box 1 .

[0034]Specifically, the electrical control device 115 automatically delivers quantitative air and gas according to the set ash removal control program, and fills the gun barrel head 3 after being fully mixed in the mi...

Embodiment 2

[0054] The following is a detailed description of the use method of a mobile gas shock wave cleaning gun in the embodiment of the present invention, as follows:

[0055] When the heating surface of a certain part of the boiler needs to be cleaned, the movable mixed ignition control box 1 of the mobile gas shock wave cleaning gun is moved to the nearest platform of the heated surface of the part, and the mixed ignition control is turned on. The power supply of the box 1, and open the air manual valve 104 of the air pipeline device and the gas manual valve 108 of the gas pipeline device by a certain ratio. Then, according to the cleaning position and distance conditions, select the flexible connection pipe 201, the hard connection pipe 202 and a certain gun barrel head 3 to be connected by a quick connector.

[0056] The soot removal operator puts the above-mentioned gun barrel head 3 deep into the position to be cleaned in the furnace through the soot removal hole of the boiler...

Abstract

The invention discloses a movable gas shock-wave ash clearing gun, and belongs to the technical filed of boiler ash clearing. The movable gas shock-wave ash clearing gun comprises an ignition controlbox; and the ignition control box specifically comprises an electrical control device, an air pipeline, a gas pipeline, a mixed ignition device, a gas delivering pipe and a set of replaceable gun barrel heads; an air inlet of the air pipeline is connected with an air source, a gas inlet of the gas pipeline is connected with a gas source, and the mixed ignition device is provided with an air inlet,a gas inlet, a mixed gas outlet, an ignition head and a connector of the ignition head; the gas delivering pipe comprises a soft connecting pipe, a hard connecting pipe and connecting accessories; and the replaceable gun barrel heads are connected with one end of the hard connecting pipe. The movable gas shock-wave ash clearing gun has the technical effects that ash clearing can be conducted in atargeted mode according to the ash accumulating situation of the heated surface of a boiler, the ash clearing efficiency is high, the movable gas shock-wave ash clearing gun is simple in structure, convenient to operate and low in production cost, and the operation failure rate of the movable gas shock-wave ash clearing gun is quite low.

Description

technical field [0001] The invention belongs to the technical field of boiler dust removal, in particular to a mobile gas shock wave dust removal gun. 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 still defects and deficiencies in the existing gas-fired shock wave ash cleaners. The main problems are limited ash removal range, many dead ends for ash removal...
