Embodiment 1

[0021] A mobile hazardous chemical cleaning and dedusting device, such as figure 1 As shown, its pressure-resistant and airtight wall is provided with a suction port 2-4 and a discharge port 2-13, the suction port 2-4 is connected to the suction head through a suction pipe, and the discharge port 2-13 is directly connected to the fan 5 In the same way, the mobile hazardous chemical cleaning and dedusting device is placed on a flexible mobile cart. The device can effectively treat the leaked hazardous chemical gas, liquid and powder substances. The container is divided into a three-phase cyclone collection section Four functional sections: gas-liquid decontamination section, separation section and collection section;

[0022] For the treatment of gaseous, liquid and powder hazardous chemicals in the factory workshop, after the fan 5 is started, after negative pressure suction, the air carrying gaseous, liquid and powder hazardous chemicals is drawn from the suction port 2- 4 I...

Embodiment 2

[0026] According to the conditions and steps described in Example 1, the device is used in a certain coal dust-containing workshop, where methanol leakage occurs in this workshop, and the main components of the exhaust gas are methanol and coal dust (the dust concentration is about 30mg / m3) at a concentration of 2000ppm. 3 ), the main component of the liquid phase is methanol liquid, and the main component of the solid phase is coal powder. Add the aqueous solution into the decontamination chamber, turn on the fan, and the liquid-gas ratio is 0.3kg / m 3 . The pumping rate of the device is about 0.15kg / s, the methanol concentration after treatment is 20ppm, and the dust concentration is reduced by 90%.

Embodiment 3

[0028] According to the conditions and steps described in Example 1, the device is used in a certain catalyst workshop, where hydrogen sulfide leaks, and the main components of the waste gas are hydrogen sulfide and catalyst dust (the dust concentration is about 50mg / m3) at a concentration of 2000ppm. 3 ), the main component of the solid phase is the catalyst. Add 4% sodium hydroxide solution into the decontamination chamber, turn on the fan, and the liquid-gas ratio is 0.1kg / m 3 . The negative pressure of the powder pumping device is about 20kPa, the hydrogen sulfide concentration after treatment is 20ppm, and the dust concentration is reduced to 5mg / m 3 .

Abstract

The invention relates to a movable hazardous chemical substance decontamination and dust removal device and applications thereof, and mainly solves the problems that hazardous chemical substance leakage of gas, liquid and powder cannot be treated simultaneously in the prior art. In the method, the movable hazardous chemical substance decontamination and dust removal device includes a hazardous chemical substance decontamination and dust removal cabin, a controller, a movable platform, and a fan, wherein the hazardous chemical substance decontamination and dust removal cabin, the controller andthe fan are all fixed to the movable platform. The hazardous chemical substance decontamination and dust removal cabin includes a three-phase cyclone collection section, a gas-liquid decontaminationsection, a separation section, and a collection section. By means of the technical scheme, the problems are solved well. The device can be used for treatment on the gas, liquid and powdery hazardous chemical substances due to leakage of a workshop.

Description

technical field [0001] The invention relates to a mobile hazardous chemical cleaning and dedusting device and its application. Background technique [0002] In recent years, accidents caused by leaking materials have occurred frequently. Once a sudden accident such as leakage of dangerous chemical gas, liquid or dust occurs in the factory workshop, the consequences will be disastrous if it is not dealt with in time. Therefore, it is necessary to carry out research and development of emergency response equipment for such emergencies. The Chinese patent "Liquid Suction and Dust Removal Device (Patent Application No.: 201510669861.3)" introduces a liquid suction and dust removal device for the leakage of liquid and powder dangerous chemicals in the workshop. Collect and process, but cannot effectively process gaseous hazardous chemicals; Chinese patent "A Movable Decontamination Device (Patent Application No.: 201010301434.7)" introduces a mobile decontamination device, which ...
