Embodiment 1

[0038] Such as figure 1 , figure 2 As shown, a schematic structural diagram of a shock wave cleaning device provided in an embodiment of the present invention, the device includes:

[0039] Shock wave cleaning unit 1;

[0040] Specifically, the shock wave cleaning unit 1 has two different structures for the air shock wave dust remover and the gas shock wave dust remover, and the specific description is as follows:

[0041] Such as figure 1 Shown is the shock wave cleaning unit in the air shock wave dust cleaner.

[0042] Such as figure 2 Shown is the shock wave ash cleaning unit in the gas shock wave ash cleaner. For the gas shock wave ash cleaner, the shock wave ash cleaning unit 1 can be a premixed detonation tank 11, which is connected with the first detonation gas inlet 21 , the second detonation gas inlet 22, and the mixed detonation gas outlet 31 are connected.

[0043] Detonation gas inlet 2, the detonation gas inlet 2 is connected to the shock wave cleaning uni...

Embodiment 2

[0069] In order to more clearly illustrate the technical solution of a shock blast detection method for shock wave cleaning provided by the embodiment of the present application, the following will describe from the perspective of the use method of the air shock wave soot cleaner and the gas shock wave soot cleaner.

[0070] 1. How to use the air shock wave dust cleaner

[0071] The compressed air enters the shock wave ash cleaning unit 1 through the detonation gas inlet 2, and the valve of the shock wave ash cleaning unit 1 is controlled to open, and the compressed air is delivered to the shock wave generator 4 through the detonation gas outlet 3, and the air delivery valve is closed after a certain amount is reached. , stop the delivery of compressed air. Then, the compressed air with a certain amount of energy in the shock wave generator 4 is released to the heating surface of the boiler by opening the release valve to complete a dust cleaning "blast" process.

[0072] 2. ...

Embodiment 3

[0075] Such as image 3 said, image 3 It is a flow chart of a blast detection method for shock wave cleaning provided by an embodiment of the present invention.

[0076] An embodiment of the present invention provides a blast detection method for shock wave cleaning, which is applied to a shock wave cleaning device, wherein the shock wave cleaning device includes a pressure sensor, and the method includes:

[0077] Step 110: Setting the effective pressure value of the blasting of the shock wave cleaning device;

[0078] Specifically, the effective pressure value of the shock wave cleaning device can be set in the control unit 6, and the effective pressure value is used to detect whether the pressure value in the actual flushing process meets the effective pressure value, and then judge the bursting whether the process was successful. The effective pressure value is determined according to different actual situations. It may be an input from the user to the control unit 6 ...

Abstract

The invention provides a burst detection method for shock wave dust cleaning. The method comprises the steps of setting an effective pressure value of burst of a shock wave dust cleaning device to check the burst effect; when the shock wave dust cleaning device bursts, acquiring the burst pressure value of the shock wave dust cleaning device; comparing the burst pressure value with the effective pressure value; and when the burst pressure value is higher than or equal to the effective pressure value, determining the burst as effective burst. According to the embodiment of the invention, through the comparison of the effective pressure value and the burst pressure value, the technical problem that misfire detection is inaccurate, high in cost and poor in effect can be effectively solved, and the burst detection method has the technical effect that misfire detection is accurate, low in cost and good in effect.

Description

technical field [0001] The invention relates to the technical field of boiler dust removal, in particular to a blast detection method for shock wave dust removal. Background technique [0002] The ash cleaner is an indispensable and important auxiliary equipment for various waste heat boilers and power plant boilers. It plays a vital role in improving the heat exchange efficiency of the boiler heating surface, that is, increasing the boiler output. There are many types of soot cleaners, such as steam soot cleaners, sonic soot cleaners, air shock wave soot cleaners and gas shock wave soot cleaners. Different types of soot cleaners have different characteristics and scope of application, but the gas Shock wave dust cleaner and air shock wave dust cleaner have many advantages that other types of dust cleaners do not have: such as large cleaning energy, stable cleaning operation, small maintenance, low operating cost and wide application range. Therefore, the market share of ga...
