Accident chlorine treatment device used in liquid chlorine production process

Abstract

The invention discloses an accident chlorine treatment device for a liquid chlorine production process, which comprises a liquid chlorine packaging workshop, a liquid chlorine storage tank workshop and a liquid chlorine packaging workshop, wherein a packaging workshop accident chlorine treatment tower and a liquid chlorine storage tank workshop accident chlorine treatment tower are arranged on theside edge of the liquid chlorine storage tank workshop; wherein a water tank is arranged at the top above the liquid chlorine packaging workshop and the liquid chlorine storage tank workshop, a sprayheader and an air collecting hood are arranged at the top inside the liquid chlorine packaging workshop and the liquid chlorine storage tank workshop, an accident fan is arranged on the side walls ofthe liquid chlorine packaging workshop and the liquid chlorine storage tank workshop, and filler is arranged in the accident chlorine treatment tower. An alkali liquor collecting pool is arranged atthe bottom of the packing workshop accident chlorine treatment tower, a circulating pipe is connected to the alkali liquor collecting pool, the top of the circulating pipe is connected with an alkaliliquor storage tank, a circulating pump is arranged on the circulating pipe, the circulating pump is connected with an alkali liquor supplementing pipe, and an SIS system is arranged in a workshop. The method has the advantages that the chlorine treatment effect is better, secondary accidents are not easily caused, and the safety is better.

Description

technical field [0001] The invention relates to a liquid chlorine production accident ventilation and accident chlorine gas treatment system, in particular to an accident chlorine treatment device used in the liquid chlorine production process. Background technique [0002] In the downstream chlorine industry of chlor-alkali, liquid chlorine is a secondary major hazard source, and liquid chlorine is stored and transported to downstream devices for use. Commonly used liquid chlorine storage is mainly storage tanks, steel cylinders, etc., and the storage of steel cylinders is limited by reserves and has greater safety hazards, so it is more common to use storage tanks for storage. According to the requirements of national standards and regulations, it is not stipulated that the building structure of liquid chlorine storage should be open or closed. In the production process of liquid chlorine, once the steel cylinders in the liquid chlorine storage tank and liquid chlorine pa...

AI Technical Summary

Problems solved by technology

In the production process of liquid chlorine, once the steel cylinders in the liquid chlorine storage tank and liquid chlorine packaging area leak, it will inevitably cause harm to the surrounding personnel and the environment

Therefore, a very strict emergency chlorine treatment process must be adopted in the liquid chlorine production process. At present, closed buildings are mostly used, and it is difficult to treat the leaked chlorine gas harmlessly.
