Chlorine leakage absorption device and method

Abstract

The invention discloses an absorbing device and method of leaked chlorine, which comprises the following parts: reaction tower, chlorine transmission pipe, aerator, ferric dichloride spout, acid-resisting pump and reservoir, wherein the reaction tower contains spray device, chlorine reaction absorption layer, escape pipe and reaction layer in the rear part of reaction tower; the reservoir connects the other end of ferric dichloride spout; the bottom of reaction tower extends in the reservoir. The method comprises the following steps: forcing the ferric dichloride into the replacement reaction layer by itself gravity; producing iron chloride; making the solution pierce the replacement reaction layer; circulating the solution in the reservoir under the reaction tower. The invention saves the absorber reaction tank and iron trichloride outlet pipe, which places the reaction part of ferric dichloride and iron under the bottom of reaction tower directly.

Description

technical field [0001] The invention relates to a chlorine leakage absorption device and method. Background technique [0002] Chlorine leakage absorption is an important process in modern factories, especially water treatment plants. If it is not handled properly, it will easily cause environmental pollution, and if the design of the process flow and equipment is unreasonable, it will increase the cost, which is extremely unfavorable for large-scale industrial production. [0003] At present, the most common chlorine release absorption device is to use sodium hydroxide for absorption. However, due to the strong corrosiveness of sodium hydroxide, the requirements for equipment are relatively high, and equipment needs to be overhauled frequently. Moreover, its absorption liquid will continue to decrease during use and needs to be added regularly, which will also cause an increase in cost. [0004] For this reason, someone proposes to use ferrous chloride solution as absorbe...

[0005] But the device proposed in this patent also has many shortcomings in actual use

One of its typical characteristics is that all the reactants involved in the reaction flow in various pipelines except iron filings, which results in many pipelines, complex equipment, and large floor space, which increases the cost and is not conducive to popularization and utilization.

Moreover, the material for reducing ferric chloride in this patent is in the form of iron filings. Since the iron filings will sink to the bottom of the absorbent reaction tank under the action of gravity, only the iron that sinks above can be in contact with ferric chloride. The contact surface is small, and the reaction is not sufficient, resulting in low absorption efficiency of the equipment, and it is difficult to meet the requirements of use
