Embodiment 1

[0045] This embodiment provides a dual-channel zoned active fire and explosion suppression system, comprising: a first pipeline, a spiral pipe, a horizontal straight pipe, a detector, a first solenoid valve, a second solenoid valve, a first controller, a second solenoid valve Two controllers, pressure relief valve.

[0046] Wherein, the spiral tube is located inside the first pipeline, and the spiral tube is detachably connected to the first pipeline; the horizontal straight tube is located inside the first pipeline, and the horizontal straight tube is connected to the first pipeline. The first pipe is detachably connected, and the horizontal straight pipe and the spiral pipe are distributed up and down.

[0047] The vertical distribution of the horizontal straight pipe and the spiral pipe can be adjusted and exchanged, for example, the horizontal straight pipe is located below the spiral pipe; or, the horizontal straight pipe is located above the spiral pipe.

[0048] The fi...

Embodiment 2

[0060] The dual-channel partitioned active fire arresting and explosion suppression system provided in Embodiment 2 is an optimization scheme based on Embodiment 1. The dual-channel partitioned active fire arresting and explosion suppression system provided in Embodiment 2 also includes: a fan , the third controller.

[0061] Wherein, the fan is located at the port of the first pipeline.

[0062] The input terminal of the third controller is connected with the detector, and the output terminal of the third controller is connected with the fan.

[0063] Installing the dual-channel partitioned active fire suppression and explosion suppression system provided in Example 2 on the gas material transportation pipeline or the dust material transportation pipeline can effectively realize the active partitioned fire suppression and explosion suppression system.

[0064] When the dual-channel zoned active fire arresting and explosion suppression system provided in Example 2 is applied ...

Embodiment 3

[0067] The dual-channel partitioned active fire arresting and explosion suppression system provided in embodiment 3 is an optimization scheme based on embodiment 1 or embodiment 2, and the dual-channel partitioned active fire arresting and explosion suppression system provided in embodiment 3 Also includes: inerting device.

[0068] The inerting device is connected with the spiral pipe.

[0069] In the event of a fire, flames enter the spiral tube, and the inerting device starts to work to inert the combustible substances in the spiral tube.

[0070] In a preferred situation, the inerting device is connected in the middle of the spiral tube, and the number of the inerting device is an integer greater than or equal to 1. The inerting device is located in the middle of the helical tube, so that the inerting medium can be sprayed into the tube more quickly and evenly, so that the fire extinguishing efficiency is higher.

[0071] The inerting medium in the inerting device is pre...

Abstract

The invention belongs to the technical field of fire and explosion prevention and discloses a dual-channel partition-type active fire-obstructing and explosion-suppressing system. The dual-channel partition-type active fire-obstructing and explosion-suppressing system comprises a first pipeline, a spiral pipe, a horizontal straight pipe, a detector, a first electromagnetic valve, a second electromagnetic valve, a first controller, a second controller and a decompression valve. According to the dual-channel partition-type active fire-obstructing and explosion-suppressing system, the problem that a fire-obstructing and explosion-suppressing system in the prior art is low in flame obstructing speed is solved, a dual-channel partition-type conveying system is adopted, through changing of the flame propagation state and path, the flame propagation tube pass is increased, and the effects of flame propagation speed effective lowering and quick fire obstruction and explosion suppression are achieved.

Description

technical field [0001] The invention relates to the field of fire prevention and explosion protection, in particular to a dual-channel partition type active fire arresting and explosion suppression system. Background technique [0002] With the continuous development of social economy and the increasing prosperity of modern industry, safety issues have become increasingly prominent. In industrial production, it is necessary to use a lot of flammable gases, such as gas, natural gas, etc., and produce a lot of dust in production, such as starch processing plants, metal processing plants, cement plants, etc., these flammable gases or dust Exists in large quantities in national production. In recent years, various accidents have occurred during the transportation of flammable gases and dusts. For example, on July 31, 2014, a flammable gas explosion occurred in Kaohsiung, Taipei, killing 28 people and injuring 285; on August 2, 2015, A particularly serious dust explosion acci...
