Description
Technical Field
The invention belongs to the field of dust removal devices, and particularly relates to a pulse bag type dust collector for automatic fire extinguishment.
Background
Dust, which is solid particles suspended in air, is a natural enemy of human health in life and work, and is a main cause of inducing various diseases. Dust can not be avoided in the production process of a workshop, if the dust is densely distributed in the whole workshop, the cleanliness of the workshop can be affected on one hand, and on the other hand, workers work in such an environment for a long time, so that the dust can enter a human respiratory system and be attached to the skin or eye conjunctiva of a human body, and the health of the human body is endangered.
At present, a large-sized bag-type pulse dust collector is basically not provided with a spray explosion suppression device, if the explosion suppression device is additionally arranged according to the dust collection system safety technical Specification for dust explosion dangerous places AQ4273-2016, because the clean air chamber space is narrow, the spray pipe needs to be detached when the bag is replaced, even if only a nozzle and a pipeline thereof are arranged, the spray explosion suppression device is additionally arranged, so that the disassembly of the spray pipe is influenced, and the spray explosion suppression effect is not ideal.
Disclosure of Invention
In order to overcome the problems, the invention provides a pulse bag type dust collector for automatically extinguishing fire, which solves the problem that the existing dust collector is poor in explosion suppression effect.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides an automatic pulse bag collector of putting out a fire which characterized in that: the device comprises a first main pipeline for conveying compressed air and a plurality of first branch pipelines which are arranged on the first main pipeline in parallel; the air supply, the first stop valve, the pneumatic triple piece, the air bag and the second stop valve are sequentially arranged on the first main pipeline, the pulse valve, the first check valve and the blowing pipe are sequentially arranged on the first branch pipeline, a plurality of blowing sub-pipes are arranged on the blowing pipe, and a cloth bag is arranged on the blowing sub-pipes. Further comprises: the second main pipeline is used for conveying explosion suppressant, and the second branch pipeline is arranged on the second main pipeline in parallel and corresponds to the first branch pipeline; an electric valve is arranged on the second main pipeline, and a second check valve is arranged on the second branch pipeline; a tee joint is arranged between the first check valve and the jetting pipe, the jetting pipe is connected to the straight pipe end of the tee joint, and the second branch pipeline is arranged at the branch pipe end of the tee joint.
Further, the electric valve is also connected with an electric control cabinet and a flame detector connected with the electric control cabinet.
The flame detector detects flame signals, the electric control cabinet transmits stop signals to all pulse valves, compressed air in the first main pipeline cannot enter the blowing pipe, meanwhile, the electric valve is opened, and explosion suppressant is sprayed into a large amount of cloth bags through the second main pipeline and the second branch pipeline through the blowing pipe and the blowing sub-pipe.
Still further, the pneumatic triplet includes a filter for filtering impurities in the compressed air, a pressure reducing valve for controlling the pressure of the system, and an oil atomizer for lubricating the downstream side element. The setting sequence of the filter, the pressure reducing valve and the oil mist device can be flexibly adjusted, and the pneumatic triple piece common in the market can be used, so that redundant description is omitted.
The invention has the beneficial effects that:
the invention fully utilizes the existing blowing pipe and blowing sub-pipe, accurately and effectively sprays the explosion suppressant into each cloth bag, and greatly improves the explosion suppression effect. By adding a first check valve on the downstream side of each pulse valve and connecting a tee, wherein the tee ends are connected to the injection pipes, the tee branch ends are connected to a second branch pipe which is connected to a first main pipe which carries the explosion suppressant. The modified pulse bag type dust collector has the functions of dust removal and explosion suppression, and has the advantages of low manufacturing cost and good explosion suppression effect.
The invention will be described in more detail below with reference to the drawings and examples.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
Examples
As shown in fig. 1, the pulse bag type dust collector for automatic fire extinguishment is provided with a dust removal system and an explosion suppression system.
Wherein, dust pelletizing system includes: a first main pipe 91 for conveying compressed air, and a plurality of first branch pipes 92 provided in parallel on the first main pipe 91.
The first main pipe 91 is provided with an air source 1, a first stop valve 2, a pneumatic triple piece 3, an air bag 4 and a second stop valve 5 in sequence.
The first branch pipeline 92 is sequentially provided with a pulse valve 6, a first check valve 7 and a blowing pipe 8, the blowing pipe 8 is provided with a plurality of blowing sub-pipes 9, and the blowing sub-pipes 9 are provided with cloth bags 10.
The pneumatic triplet 3 includes a filter 31 for filtering impurities in the compressed air, a pressure reducing valve 32 for controlling the system pressure, and an oiler 33 for lubricating the downstream side element.
The explosion suppression system comprises: a second main pipe 93 for conveying explosion suppressant, and a second branch pipe 94 provided in parallel to the second main pipe 93 and corresponding to the first branch pipe 92. The explosion suppressant is fire water or tap water.
The second main pipe 93 is provided with an electric valve 11, and the second branch pipe 94 is provided with a second check valve 12.
