An operator adds the treating agent into the treating agent bin 2-1 through the atmosphere communicating pipe 2-1-1, and the treating agent bin 2-1 is also communicated with the outside through the atmosphere communicating pipe 2-1-1. The inner wall of the upper part of the treating agent bin 2-1 is connected with an annular baffle 2-1-5 in a hanging way at the inner side of the atmosphere communicating hole, the lower part of the annular baffle 2-1-5 is immersed into the treating agent in the treating agent bin 2-1, and the annular baffle 2-1-5 surrounds the Venturi tube 2-5. The upper part of the treating agent bin 2-1 is provided with a liquid circulation hole 2-1-2. An annular cover is led out downwards from the throat 2-5-5 of the Venturi tube 2-5, an annular liquid inlet cavity 2-5-2 is formed between the annular cover and the Venturi tube 2-5, the annular cover extends to the straight pipe section 2-5-1 through the contraction pipe section 2-5-3 of the Venturi tube 2-5, the tail end of the annular liquid inlet cavity 2-5-2 is located in the treating agent bin 2-1, and the tail end of the annular liquid inlet cavity 2-5-2 is located in the treating agent bin 2-1. The upper part of a diffusion pipe section 2-5-4 of the Venturi pipe 2-5 is provided with a condenser 2-4, the condenser 2-4 is connected with the upper part of a retreatment bin 2-3, the retreatment bin 2-3 is filled with filler, the lower part of the retreatment bin 2-3 is provided with a gas-liquid circulation hole, the casing is covered with the condenser 2-4 and the retreatment bin 2-3, and the retreatment bin 2-3 is connected with a treating agent bin 2-1 through a support column. The lower part of the shell is connected with the upper part of the treating agent bin 2-1, the atmosphere communication hole is positioned outside the shell, the outer side of the side wall of the reprocessing bin 2-3 is provided with a spiral flow deflector 2-2-1, and a demisting bin 2-2 with a spiral annular cavity is formed between the reprocessing bin 2-3 and the shell through the spiral flow deflector 2-2-1.

The preferred specific structure of the hazardous chemical substance leakage emergency disposal system in this embodiment is as follows: under the action of the fan 4, gas, liquid and solid hazardous chemical substances enter from the suction port 1-1 through a pipeline and then impact the separation partition plate 1-2, gas, liquid and solid are separated under the action of inertia, and partial waste liquid and solid particles slide down along the separation partition plate 1-2 and enter the collection bin 1-3. Other gas-liquid hazardous chemicals carrying waste liquid steam flow along the airflow channel between the separation partition plate 1-2 and the collection bin 1-3 and enter the straight pipe section 2-5-1 of the venturi pipe 2-5. The gas-liquid hazardous chemical with the waste liquid steam enters a contraction pipe section 2-5-3 of the Venturi pipe 2-5, the air flow speed at the outlet of the contraction pipe section 2-5-3 reaches the maximum to form a low-pressure area, and the treating agent in the treating agent bin 2-1 is injected into the Venturi pipe 2-5 under the action of the internal and external pressure difference. Because the preferred specific structure of the dangerous chemical leakage emergency disposal system in this embodiment needs to be moved frequently for use, for example, when the system is loaded on a vehicle, the disposal agent in the disposal agent bin 2-1 will shake, and the disposal agent is liable to slip from the annular liquid inlet cavity 2-5-2 in the venturi tube 2-5, which affects the entry of the disposal agent into the venturi tube 2-5. An annular baffle 2-1-5 is connected to the inner wall of the upper part of the treating agent bin 2 at the inner side of the atmosphere communicating hole in a hanging manner, and the annular baffle 2-1-5 surrounds the Venturi tube 2-5. The annular baffle 2-1-5 surrounds the Venturi tube 2-5 to form a relatively closed space, so that the shaking degree of the treating agent at the inlet of the annular liquid inlet cavity 2-5-2 of the Venturi tube 2-5 can be reduced, and the treating agent is prevented from sliding from the annular liquid inlet cavity 2-5-2 in the Venturi tube 2-5. The treating agent and the gas-liquid hazardous chemical with the waste liquid steam contact and transfer mass and react in the diffusion pipe section 2-5-4 of the Venturi pipe 2-5. As the treating agent enters the venturi tube 2-5, the liquid level of the area inside the treating agent bin 2-1 drops, and the annular baffle 2-1-5 divides the treating agent bin 2-1 into two areas (inner area and outer area), and when the treating agent liquid level of the inner area of the treating agent bin 2-1 drops, the treating agent in the outer area is automatically supplied to the inner area due to the atmospheric pressure and the liquid level difference. After the gas-liquid hazardous chemical substance carrying the waste liquid steam and the treating agent are contacted and transferred in the diffusion pipe section 2-5-4 of the Venturi pipe 2-5 and react, the gas-liquid mixture carrying the treating agent separates gas from the treating agent liquid under the action of the condenser 2-4, and the gas-liquid mixture continuously enters the retreatment bin 2-3. In the reprocessing chamber 2-3, the gas flow flows downwards along the filler, and the gas-liquid mixture and the treating agent are subjected to mass transfer and reaction on the surface of the filler layer. When the gas-liquid mixture reaches the bottom of the reprocessing chamber 2-3, the gas enters the demisting chamber 2-2 through the gas-liquid flow through hole, and the treating agent absorbing the hazardous chemical waste gas and the waste liquid enters the treating agent chamber 2-1 through the liquid flow through hole 2-1-2. Under the action of the spiral flow deflector 2-2-1, airflow generates rotational flow upwards in the demisting bin 2-2 of the spiral annular cavity, small liquid drops are thrown to the shell, gas and liquid are separated again, the liquid flows downwards along the spiral flow deflector 2-2-1 and flows into the treating agent bin 2-1 through the liquid through hole 2-1-2, the gas upwards rotates upwards and flows into the rotational flow liquid storage bin 3-1 through the fan 4, the mist rotates in the rotational flow liquid storage bin 3-1 to further demist and remove dust, and the gas is further adsorbed in the adsorption bin 3-2 to meet the emission requirement and is discharged through the discharge port 3-3. The hazardous chemical substance leakage emergency disposal system in the embodiment can recover and dispose the hazardous chemical substance leakage liquid, solid and volatile gas at the same time, the treatment process is rapid, efficient and sufficient, all sections can be combined and divided at will, and the system is easy to maintain.
