Problems solved by technology

[0003] For the current dust collector, there are various forms such as electric dust collector, cloth bag dust collector and electric cloth combined dust collector. The connection between the dust collector and the bag filter adopts a direct connection or a flue connection. The structure of the electric cloth dust collector makes the flow track of the exhaust gas single. When the electric dust collector needs to be repaired or cleaned, it needs to be completely stopped. The entire electric cloth can be overhauled in conjunction with the dust collector. Such overhaul will undoubtedly affect the entire production and reduce the production efficiency of the enterprise.
In the past, there was a lack of dust removal equipment that can realize full-line offline dust removal equipment, and it is necessary to realize the maintenance of dust removal equipment under the condition of ensuring safe production

Embodiment approach 1

[0017] Embodiment 1: During normal operation, the third valve is closed, the second valve and the first valve 3 are opened, and the dusty exhaust gas enters from the air inlet 7, passes through the second valve, enters the electrostatic precipitator part 1 for dust removal, and then leads to the bag dust removal Part 2, and finally discharged from the outlet of the bag dust removal part 2; when it is necessary to overhaul the electrostatic precipitator part 1, close the first valve 3 and the second valve, open the third valve, and the dusty exhaust gas enters from the air inlet 7 , leading to the bag dust removal part 2 through the third valve, at this time, the electric dust removal part 1 can be overhauled and cleaned. When the electric dust removal part 1 is cleaned, the first valve 3 and the second valve are opened to make the dust collector continue Normal work, in order to operate conveniently, the second valve and the third valve are doubled as by a reversing valve 4.

Embodiment approach 2

[0018] Embodiment 2: When the dust collector is working normally, the dusty waste gas enters the electrostatic precipitator part 1 through the reversing valve 4 from the air inlet, then enters the bag dust removal part 2 through the first valve 3, and finally flows out from the bag dust removal part 2.

[0019] There are two dust removal chambers in the electrostatic precipitator part 1, and four dust removal chambers in the bag dust removal part 2. When it is necessary to overhaul and clean the electrostatic precipitator chamber 5 of the electrostatic precipitator part 1, first close the inlet of the electric dust removal chamber to be repaired. The air valve and the air outlet valve make the dust-laden exhaust gas pass from another electrostatic precipitator to the bag dust removal part 2 to complete the maintenance and cleaning of the electric dust removal room; when it is necessary to overhaul the bag dust removal room 6 behind, use the same method , close the air inlet val...

Abstract

The invention relates to the technical field of environmentally friendly dust collecting equipment, in particular to a dust collector. For the purpose of solving a defect that the traditional dust collector needs to be turned off when being maintained in a production process, the invention provides the dust collector which is provided with an electric dust collecting part and a cloth bag dust collecting part, wherein a first valve capable of being connected or disconnected is arranged between the electric dust collecting part and the cloth bag dust collecting part; a second valve is arranged between an air inlet and the electric dust collecting part of the dust collector; a third valve is arranged between the air inlet and the cloth bag dust collecting part of the dust collector; an air outlet of the dust collector is arranged on the cloth bag dust collecting part. A flow direction of waste gas is changed by opening and closing the valves at the different positions, so that off-line maintenance is carried out on the parts where no waste gas flows through of the dust collector. The dust collector is applicable to enterprises with more emission of dusty gas, such as cement plants and metallurgical plants, and industries including waste incineration and the like.

Description

technical field [0001] The invention relates to the technical field of dust removal devices, in particular to a dust collector capable of realizing full-line off-line maintenance. Background technique [0002] With the rapid development of the economy and the enhancement of people's awareness of environmental protection, the dust removal requirements for industrial coal combustion are also increasing. For some enterprises that emit a lot of dusty gas, such as cement plants, metallurgical plants, and waste incineration industries, they are facing huge challenges. challenge. [0003] For the current dust collector, there are various forms such as electric dust collector, cloth bag dust collector and electric cloth combined dust collector. The connection between the dust collector and the bag filter adopts a direct connection or a flue connection. The structure of the electric cloth dust collector makes the flow track of the exhaust gas single. When the electric dust collector...
