Embodiment Construction

[0040] A new process for treating chlorine-containing waste gas with activated carbon fiber adsorption-catalysis function. Its process is as follows: First, the activated carbon fiber is loaded into the absorption tower with a filling thickness of 800mm, so that 2.0~10.0 g / Nm 3 After chlorine-containing exhaust gas enters the humidification tower at a flow rate of 40 L / min, the temperature reaches 50oC and the humidity is 60 g / m 3 Then it is pumped into the absorption tower to carry out the adsorption-catalytic conversion process. The treated chlorine-containing waste gas is sprayed by a foam spreader and then discharged up to the standard. The exhausted chlorine-containing waste gas that meets the standard is sampled and analyzed every half hour. The concentration of chlorine-containing waste gas reaches 0.05~0.3 g / Nm 3 , it is regarded as the adsorption capacity is saturated; the chlorine gas adsorbed by the activated carbon fiber has been catalyzed into a hydrogen chloride ...

Abstract

The invention provides a novel technology for treating waste gas containing chlorine with the adsorption-catalysis function of active carbon fibers, comprising the following process flows of: firstly, filling the active carbon fibers into an absorption tower, enabling the waste gas containing chlorine to enter a humidifying tower, then pumping into the absorption tower, carrying out an adsorption-catalytic conversion process, paving foam on the treated waste gas containing chlorine with a foam paving device, and carrying out standard discharge, wherein when the adsorption capacity is saturated, chlorine adsorbed by ACF (Active Carbon Fiber) is catalytically converted to a hydrogen chloride solution and is resolved under the working conditions. The used ACF is novel activated carbon which is invented in recent ten years and is widely popularized and used in every field at present. In the ACF, the adsorption capacity is larger than that of active carbon by 10 times, the adsorption, catalysis and resolution speed is larger than that of the active carbon by 10-100 times, the resolution steam temperature is greatly lowered, and only 1000 DEG C steam is needed for regeneration, therefore, compared with the activated carbon, the conditions of the ACF are greatly lowered, and the ACF is beneficial to efficiently using in production, thereby lowering the field production cost and being easily used in a regenerated and repeated way.

Description

technical field [0001] The invention relates to a process for treating chlorine-containing waste gas, in particular to a new process for treating chlorine-containing waste gas with the adsorption-catalytic conversion function of activated carbon fiber (ACF) material in chlorination metallurgy and chlor-alkali industrial production. Background technique [0002] In the production process of chlorination metallurgy and chlor-alkali industry, chlorine-containing waste gas will be produced. Chlorine-containing waste gas is a serious pollutant. In recent years, economic and human losses caused by leakage of chlorine-containing waste gas have occurred frequently around the world. In the First World War, chlorine-containing gas was used as poisonous gas in the war, so the treatment of chlorine-containing waste gas pollution sources is a very difficult global issue. [0003] Common chlorine-containing waste gas treatment methods include: water absorption method, lye absorption meth...
