Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] A chlorine leakage treatment system consists of an accident treatment room 1, an accident fan 2, a first lye absorption tower 3, a second lye absorption tower 4, an lye circulation tank 5, an lye circulation pump 6, an lye cooler 7, Vacuum pump 8 and flammable and poisonous alarm instrument 9 are implemented in combination. The accident treatment room 1 is composed of a main structure, a passage port 10, a gas outlet pipe 11 and an outlet pipe control valve 12, which can realize the centralized collection of leaked chlorine gas caused by the failure of the bottle body structure during the vaporization process. Functional relatively closed space structure, ...

Abstract

The invention relates to the technical field of emergency treatment of dangerous chemical leakage, and discloses a concentrated collection and treatment system of leaked chlorine. The concentrated collection and treatment system of the leaked chlorine comprises an accident treatment chamber and an accident fan arranged in the accident treatment chamber, wherein an outlet pipeline of the accident fan is connected with the bottom of a first alkali liquor absorption tower, the first alkali liquor absorption tower is in series combination with a second alkali liquor absorption tower, the first alkali liquor absorption tower and the second alkali liquor absorption tower are connected with an alkali liquor circulating groove, an inlet pipeline of an alkali liquor circulating pump is connected with the bottom of the alkali liquor circulating groove, an outlet pipeline of the alkali liquor circulating pump communicates with an alkali liquor cooler, an outlet pipeline of the alkali liquor cooler is connected with the upper portions of the first alkali liquor absorption tower and the second alkali liquor absorption tower separately, a top outlet pipeline of the first absorption tower is connected with a bottom inlet pipeline of the second absorption tower, and a top outlet pipeline of the second absorption tower is connected with a vacuum pump. By means of the concentrated collection andtreatment system of the leaked chlorine, body damage, which is caused by contact between alkali liquor and an operator and contact between chlorine and the operator, is effectively avoided, and precipitation of crystals of NaClO resolvent NaCl is reduced, so that the problem of cleaning an alkali liquor absorption tank is effectively eradicated.

Description

technical field [0001] The invention relates to the technical field of emergency treatment of hazardous chemical leakage, in particular to a centralized collection and disposal system for leaked chlorine gas. Background technique [0002] Under the current technical conditions, the liquid chlorine cylinders in the chemical production industry may accidentally leak due to the failure of the cylinder structure during the use of hot water spray to heat the cylinders for vaporization. The traditional disposal method is to quickly isolate the leaking cylinders from the production and operation system After cutting off, transport it to the lye absorption tank to absorb the leaked chlorine gas by lifting the crane. The reaction mechanism is that Cl 2 +NaOH=NaCl+NaClO+H 2 O+Q, the reaction is exothermic. There are many disadvantages in this treatment method, as detailed below: [0003] 1) During the process of using the lifting equipment to transport the leaked steel cylinder to ...
