Problems solved by technology

[0002] At present, in the production, storage, transportation, sales, use and disposal of hazardous chemicals, accidents such as fire, explosion, leakage and poisoning have occurred from time to time, causing heavy casualties, property losses and environmental pollution.
And the existing problem of hazardous chemical leakage emergency treatment device is: one, the emergency treatment device has a single function
2. Cannot effectively control the solution preparation speed
Third, the discontinuity of the solution preparation process
Most of the existing mixing devices are phased preparation of solute and solvent, and phased supply of decontamination solution is not allowed for larger accidents.

Embodiment 1

[0015] Such as figure 1 , the hazardous chemical leakage accident emergency treatment device of the present invention mainly includes a mixing chamber 11 and a liquid storage chamber 12 formed by adding an extended partition 20 in the middle of a liquid tank 22 . The extension length of the top plate and the bottom plate of the liquid tank 22 is equal to that of the extension partition plate 20 , and angle irons 23 are welded on the outer edges of the three-layer extension plate to form a steel frame 21 . The mixing chamber 11 and the liquid storage chamber 12 are only connected through an external pipeline, and an electric ball valve 31 is added in the middle of the pipeline, and the electric ball valve 31 and the pipeline are all connected by flanges. A control valve VII18 is added to the liquid outlet of the stirring chamber 11, and the liquid supply port of the control valve VII18 and the stirring pump 6 and the flange with an elbow are all threaded. The stirring pump 6 i...

Embodiment 2

[0018] On the basis of embodiment 1, implement the preparation and spraying of solution, specific method; According to the accident scene of chlorine leakage, it is necessary to prepare 5% bleach solution 2000L and spray evenly

[0019]The specific operation is as follows: the net capacity of the mixing chamber is 500L, the delay time of the electric ball valve is adjusted to 3 minutes according to the amount of powder to be fed once, the fire-fighting interface is connected to the water source, and bleach is added to the hopper. Start the automatic proportioning button, open the electric ball valve to supply water to the stirring liquid tank, when the water level reaches the start value of the stirring pump preset by the liquid level gauge, the stirring pump starts, the electric ball valve opens, and starts to supply bleaching powder from the hopper to the stirring liquid tank, and at the same time, the stirring pump A liquid circulation is formed between the stirring liquid t...

Embodiment 3

[0021] Backfilling a Cracked Chlorine Tank

[0022] The specific operation is as follows: the ruptured chlorine gas tank cannot be used any longer, and the spray pump 1 can be used for reverse irrigation if necessary. Connect the fire hose to the fire hydrant on the branch road of the tee pipe II, and connect the other end of the fire hose to the interface of the ruptured chlorine tank. The three-way pipe at the liquid outlet of the spray pump is connected to the connecting pipe on the fire hydrant, and the other end of the fire hose is connected to the air inlet of the new gas tank. Start the sprinkler pump for back irrigation. When pouring is over, press the stop button.

Abstract

The invention discloses an emergency treatment device for dangerous chemical leakage. A partition plate is arranged in the middle of a liquid tank to form a structure taking upper and lower stirring chambers and a liquid storage chamber as a main body; the bottom of the liquid tank and the extending outer edge of the middle partition plate are provided with a steel plate framework with an upper layer and a lower layer; a stirring pump is fixed on the middle extending partition plate; an ejector inlet is communicated with the stirring pump, while an outlet is communicated with the stirring chambers; an electric ball valve is arranged at an ejector negative pressure port and communicated with a four-way pipe; a hopper is arranged on the upper part of the four-way pipe; and a spray pump is fixed on a lower extending steel plate, a liquid inlet of the spray pump is communicated with a liquid outlet of the liquid storage chamber, a liquid outlet of the spray pump is communicated with a three-way pipe II, and the other two ports of the three-way pipe II are connected with a hydrant I and a control valve I respectively. The device is suitable for emergency treatment of accidents in production, storage, transportation, selling, use and waste treatment of dangerous chemicals, and avoids heavy casualties, property loss and environmental pollution.

Description

technical field [0001] The invention relates to an emergency treatment device for leakage of hazardous chemicals, in particular to an emergency treatment device for leakage of solid, liquid and gaseous hazardous chemicals. technical background [0002] At present, in the production, storage, transportation, sales, use and disposal of hazardous chemicals, accidents such as fire, explosion, leakage and poisoning occur frequently, causing heavy casualties, property losses and environmental pollution. However, the problems existing in the emergency treatment device for leakage of hazardous chemicals are: 1. The function of the emergency treatment device is single. Due to the uncertainty of pollution events, the state of the prepared solute is also uncertain, which may be any of solid, liquid and gas. Two, can not effectively control the solution preparation speed. Some chemicals are relatively active in nature, and there may be violent reactions in the process of preparing sol...
