Movable anti-explosion vacuum dust collection device and anti-explosion control method thereof

Abstract

The invention provides a movable anti-explosion vacuum dust collection device and an anti-explosion control method thereof. The movable anti-explosion vacuum dust collection device comprises a vacuum dust collector located on a movable platform (1), and an inerting protection system. The inerting protection system comprises an inerting gas storage tank (2), a main control valve (4), inerting dustproof spray nozzles (5), a valve position signal feedback device (6) of the main control valve (4), a detector used for detecting the CO concentration or / and temperature in a material bin (3), an extinguishment control cabinet (7) and a release controller (8). The anti-explosion control method includes the following steps that when the detector detects that the temperature of the material bin (3) rises to a set value or detects that the CO concentration exceeds a set value, the detector transmits detection information to the extinguishment control cabinet (7), the extinguishment control cabinet (7) supplies power to the release controller (8), the release controller (8) makes inerting gas delivered to the main control valve (4), the main control valve (4) is opened, the inerting gas is sprayed through the inerting dustproof spray nozzles (5), or workers receive and confirm alarm signals and then start the system.

Description

technical field [0001] The invention relates to the field of dust removal technology, in particular to a mobile explosion-proof vacuum cleaner, and also relates to an explosion-proof control method for the mobile explosion-proof vacuum cleaner. Background technique [0002] The dust removal device is equipment equipped in many production industries. Its function is to collect and remove the dust at the dusty place, thereby reducing the amount of dust discharged into the atmosphere. It is an important environmental protection equipment to improve environmental pollution and air quality. Vacuum (negative pressure) dust collection is widely used in cement, steel, thermal power generation and other industries. It collects dusty materials from containers or scattered ground through suction nozzles, piping systems, and into vehicle hoppers, mobile cars or trailers; and collects The material in the hopper is transported and unloaded to the designated place.

Problems solved by technology

However, when a fire occurs, there is no active fire extinguishing device, which is not conducive to safe production

[0004] Although the existing mobile vacuum (negative pressure) dust collection device is equipped with an explosion-proof valve, when the explosion is released, the high-temperature and high-pressure dust explosion products and unburned dust clouds are ejected from the explosion-venting hole, causing a secondary explosion and causing damage to the surrounding area. The environment poses new threats
