According to the utility model, under the process condition of the existing pressure reducing valve, one pressure reducing valve is added, a bypass stop valve is arranged behind the two pressure reducing valves for communication, and the two pressure reducing valves respectively reduce pressure before the bypass stop valve is opened; when one pressure reducing valve is damaged, the bypass pressure reducing valve is opened, so that two paths of pressure reduction can be realized by one pressure reducing valve, namely, the two pressure reducing valves are mutually standby, and the reliability and the availability of the gas circuit of the dust remover are improved.
Description
Technical Field
The utility model relates to the technical field of environmental protection, in particular to a decompression gas circuit of a bag-type dust remover.
Background
The pressure reducing valve (which reduces the pressure of 0.8MPa compressed air at the outlet of an air compressor to 0.2-0.4 MPa) on a compressed air path of the prior bag-type dust collector is generally one. The gas passing amount of relief pressure valve is limited, and when the relief pressure valve became invalid, perhaps not decompress or the air was no longer passed through, and the gas circuit system that causes whole dust remover all can receive the influence and became invalid, the too high filter bag that leads to of jetting atmospheric pressure received highly-compressed air to erode, reduce filter bag life, the air can cause the filter bag to can not spout when passing through, thereby lead to the dust remover resistance to rise, the draught fan load increase, can cause boiler flue gas to go out the cigarette not smooth when serious, form the furnace malleation, there is boiler explosion hidden danger.
Disclosure of Invention
The utility model aims to solve the problem of failure of a pressure reducing valve of a gas path of a dust remover, and provides a pressure reducing gas path of a bag-type dust remover, which is additionally provided with a pressure reducing valve and a bypass stop valve, so that the two pressure reducing valves are mutually standby, and the reliability and the usability of the gas path of the dust remover are improved.
The utility model adopts the following technical scheme:
a bag-type dust collector pressure reduction gas circuit is provided, high-pressure air is divided into a first path and a second path, the first path provides high-pressure gas for a first off-line cylinder after passing through a first gas source triplet, a first ball valve and a first pressure gauge are arranged in front of the first gas source triplet, a second ball valve is connected on the first gas source triplet in parallel, a third ball valve and a first electric contact pressure gauge are arranged behind the first gas source triplet, the second path provides high-pressure gas for a second off-line cylinder after passing through a second gas source triplet, a fourth ball valve and a second pressure gauge are arranged in front of the second gas source triplet, a fifth ball valve is connected on the second gas source triplet in parallel, a sixth ball valve and a second electric contact pressure gauge are arranged behind the second gas source triplet,
one end of the first pressure reducing valve is connected between the first ball valve of the first path and the first air source triplet, and the other end of the first pressure reducing valve is connected with the first air bag through a first butterfly valve;
one end of a second pressure reducing valve is connected between a fourth ball valve of the second path and the second air source triplet, and the other end of the second pressure reducing valve is connected with a second air bag through a second butterfly valve;

The utility model has the advantages that:
1. according to the utility model, under the process condition of the existing pressure reducing valve, one pressure reducing valve is added, a bypass stop valve is arranged behind the two pressure reducing valves for communication, when one pressure reducing valve fails, the bypass stop valve is opened, and compressed air decompressed by the other pressure reducing valve can be led to the path, namely: before the bypass stop valve is not opened, the two pressure reducing valves respectively reduce the pressure; when one pressure reducing valve is damaged, the bypass pressure reducing valve is opened, so that one pressure reducing valve can be used for reducing pressure in two ways, namely the two pressure reducing valves are mutually standby, and the reliability and the availability of the gas circuit of the dust remover are improved; 2. the one-to-one correspondence between the pressure reducing valve and the equipment, namely 'each pipe', is realized, and the problem that the pressure reducing air quantity of the existing pressure reducing valve is limited is solved.
Description of the drawings fig. 1 is a schematic view of the overall structure of the present invention.
The present invention will be further described with reference to the accompanying drawings.
As can be seen from fig. 1, a bag-type dust collector pressure-reducing gas path, in which high-pressure air is divided into a first path and a second path, the first path provides high-pressure gas for a first off-line cylinder 7 after passing through a first gas source triplet 3, a first ball valve 1 and a first pressure gauge 2 are arranged in front of the first gas source triplet 3 for monitoring the pressure of the high-pressure gas, a second ball valve 4 is connected in parallel to the first gas source triplet 3, a third ball valve 5 and a first electric contact pressure gauge 6 are arranged behind the first gas source triplet 3 for monitoring the pressure of the high-pressure gas, the second path provides high-pressure gas for a second off-line cylinder 12 after passing through a second gas source triplet 16, a fourth ball valve 17 and a second pressure gauge 18 are arranged in front of the second gas source triplet 16, a fifth ball valve 15 is connected in parallel to the second gas source triplet 16, a sixth ball valve 14 and a second electric contact pressure gauge 13 are arranged behind the second gas source triplet 16,
one end of a first pressure reducing valve 21 is connected between the first ball valve 1 and the first air source triplet 3 in the first path, and the other end of the first pressure reducing valve 21 is connected with a first air bag 8 through a first butterfly valve 9;
one end of a second pressure reducing valve 19 is connected between a fourth ball valve 17 and a second air source triplet 16 of the second path, and the other end of the second pressure reducing valve 19 is connected with the second air bag 10 through a second butterfly valve 11;
the other end of the first pressure reducing valve 21 and the other end of the second pressure reducing valve 19 are connected by a bypass cut-off valve 20.
When the bypass stop valve is used, the bypass stop valve is closed in a normal state, the first pressure reducing valve provides low-pressure gas for the first air bag, and the second pressure reducing valve provides low-pressure gas for the second air bag; when one pressure reducing valve fails, the bypass stop valve is opened, and low-pressure gas is supplied to the two gas bags by one pressure reducing valve at the same time.
