Embodiment 1

[0046] Such as figure 1 As shown, the bag filter (filter, dust collector) online high-precision fixed-point side-shooting type leak detection device of the present invention includes an optical signal transmitting subsystem, an optical signal receiving subsystem, a signal processing subsystem, and a signal display subsystem. system, and an integrated control subsystem, in which:

[0047] Such as figure 2 As shown, the optical signal transmitting subsystem 11 is installed on the side wall above the flower plate 14 (upper box) of the bag filter box 13 for sending out optical signals;

[0048] The optical signal receiving subsystem 12 is installed vertically on the adjacent side wall for receiving the optical signal sent by the optical signal transmitting subsystem 11;

[0049] The signal processing subsystem, signal display subsystem and signal control subsystem are all arranged outside the bag filter, wherein:

[0050] The signal processing subsystem is used to receive the ...

Embodiment 2

[0065] Such as image 3 Shown is the second embodiment of the bag filter (filter, dust collector) online high-precision fixed-point side-shooting type leak detection device of the present invention, and its difference from Embodiment 1 is: the signal transmitting subsystem 11 includes a light source 6 and an optical fiber 7 with an optional optical splitter, and the signal receiving subsystem 12 includes a sensor 8 and an optical fiber 9 with an optional optical splitter; the light source 6 uses near-infrared light.

[0066] When detecting the first row, the near-infrared light emitted by the light source 6 passes through the optional beam splitter to select the first row, and the light is totally reflected to the first row through the optical fiber 7, and emits near-infrared light, which is received by the sensor 8 of the corresponding optical fiber 9 Near-infrared light; when the second row is detected, the optical splitter selects the second row to open the optical path, an...

Abstract

The invention discloses an on-line high-precision fixed point side emitting type leak detection device for a bag type dust remover. The leak detection device comprises an optical signal emitting subsystem, an optical signal receiving subsystem, a signal processing subsystem, a signal displaying subsystem, and an integrated control subsystem, wherein the optical signal emitting subsystem is mounted on a side wall above a pattern chain of the box body of the bag type dust remover, and used for emitting optical signals; the optical signal receiving subsystem is perpendicularly mounted on a side wall adjacent to the optical signal emitting subsystem, and used for receiving the optical signals emitted by the optical signal emitting subsystem; all of the signal processing subsystem, the signal displaying subsystem and the integrated control subsystem are arranged outside the dust remover. The invention further discloses a leak detection method based on the leak detection device. The leak detection device and method can be used for quickly and accurately locating the position of a broken filtering bag, so as to replace the broken filtering bag in time.

Description

technical field [0001] The invention belongs to the field of environmental protection, specifically relates to the technical field of powder gas purification and collection, and more specifically relates to an online high-precision fixed-point side-shooting type leak detection device and a leak detection method for a bag filter. Background technique [0002] While my country's economy is developing, dust pollution from all walks of life is becoming more and more serious. At present, in the production process of food, construction, chemical industry, metallurgy, glass, cement, waste incineration, electric power and other industries, a large amount of dust will be generated. In order to purify or collect these dusts, all walks of life have designed various dust collectors. Among them, the bag filter has been widely used due to its unique characteristics of high collection efficiency, continuous operation, strong adaptability to operating load changes, large processing gas vol...
