Description

Self-diagnosis wet dust removal device

Technical Field

The utility model belongs to the dust collecting equipment field, concretely relates to self-diagnosis wet dedusting device.

Background

The bag type dust collector collects solid particles in dust-containing gas by using a fiber filter material to form a filter dust cake, and fine dust particles are further filtered by the filter dust cake so as to achieve the purpose of high-efficiency dust removal. However, the filter material in the bag-type dust collector is damaged due to the pressure and frequency of electromagnetic blowing, high temperature in the tail gas, high water vapor content, corrosion and other problems, so that dust in the tail gas leaks out, and an environmental pollution event occurs. The above problems become more serious as the filter bag is used for a longer period of time. At present, although great progress is made in the aspects of filter bag materials and the like, the phenomenon cannot be completely eradicated at present.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved is as follows: to the technical problem, the utility model provides a self-diagnosis wet dedusting device starts work when the sack cleaner breaks down, guarantees that tail gas emission to reach standard.

The technical scheme is as follows: the utility model provides a self-diagnosis wet dedusting device, includes clean room, dust sensor, intake pipe, acoustical panel, shower, sensor self-modulation valve and draught fan, the clean room is divided into three region by air inlet to gas outlet, is first dust removal district, second dust removal district and the district of making an uproar of falling respectively, all set up the shower in first dust removal district and the second dust removal district, set up the acoustical panel in the district of making an uproar of falling, set up sensor self-modulation valve on the shower, the air inlet and the intake-tube connection of clean room, set up dust sensor and draught fan in the intake pipe, dust sensor and sensor self-modulation valve are connected.

Preferably, a partition plate is arranged between the first dust removing area and the second dust removing area and between the second dust removing area and the noise reduction area.

Further, the partition board is a breathable and waterproof partition board.

Preferably, a plurality of spiral spray heads are arranged on the spray pipe.

Preferably, the side walls of the first dust removing area and the second dust removing area are provided with drain pipes.

Furthermore, a water suction pump is arranged on the water discharge pipe.

Preferably, an air outlet pipe is arranged at an air outlet of the dust chamber.

Has the advantages that: 1) The tail gas exhaust device can be combined with a bag-type dust remover for use, and when the dust exceeds the standard due to damage of a filter bag of the bag-type dust remover, cracking of a pattern plate and the like, the tail gas can be ensured to be exhausted up to the standard; 2) The workload of field workers for cleaning the accumulated alkali blockage is reduced, and the working strength of field operators is reduced; 3) The sprayed washing water can be recycled, so that the cost is saved; 4) The device has wide applicability, can be used in combination with systems such as mechanical dust removal, cloth bag dust removal and the like, and can also be used for removing dust independently; 5) Simple structure and basically no maintenance.

Drawings

FIG. 1 is a schematic view of the present invention;

sequence numbers in the figure: 1. the dust removal device comprises a dust removal chamber, 2 parts of a drain pipe, 3 parts of a first dust removal area, 4 parts of a dust sensor, 5 parts of an air inlet pipe, 6 parts of an air outlet pipe, 7 parts of a noise reduction area, 8 parts of a second dust removal area, 9 parts of a spray pipe, 10 parts of a sensor self-adjusting valve, 11 parts of a motor, 12 parts of an induced draft fan.

Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

Example 1

Referring to fig. 1, a self-diagnosis wet dedusting device, including clean room 1, dust sensor 4, intake pipe 5, abatvoix 7, shower 9, sensor self-modulation valve 10 and draught fan 12, clean room 1 is divided into three region by ventilative impervious baffle by air inlet to gas outlet, is first dust removal district 3, second dust removal district 8 and falls the district 7 of making an uproar respectively, all set up shower 9 in first dust removal district 3 and the second dust removal district 8, be equipped with a plurality of spiral shower nozzles on the shower 9, fall and set up the abatvoix in the district 7 of making an uproar, set up sensor self-modulation valve 10 on the shower 9, the air inlet and the intake pipe 5 of clean room 1 are connected, set up dust sensor 4 and draught fan 12 on the intake pipe 5, dust sensor 4 is connected with sensor self-modulation valve 10, the gas outlet of clean room (1) is equipped with outlet duct (6).
