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 .
