Adsorption medium service life indicating device of dry type special gas tail gas treatment equipment

Abstract

The invention provides an adsorption medium service life indicating device of dry type special gas tail gas treatment equipment. The adsorption medium service life indicating device comprises a steelpipe (1), a toxic gas detection device (2), an equipment gas inlet opening (3), a pneumatic pump (4), a stainless steel corrugated pipe (5) and a transparent PVC hose (6), wherein one end of the steelpipe (1) is inserted into a 90-percent position of the adsorption medium at the bottom of the adsorption medium container; the other end of the steel pipe (1) is connected with the gas inlet of the toxic gas detection device (2) positioned outside the adsorption medium container; one end of the pneumatic pump (4) is connected with an air outlet of the toxic gas detection device (2); the other endof the pneumatic pump (4) is connected with the equipment gas inlet opening (3); the toxic gas detection device (2) is used for determining the passing gas concentration; the pneumatic pump (4) is started to work; a gas sample at a connecting position of the steel pipe (1) and the 90-percent position of the adsorption medium is extracted and flows through the toxic gas detection device through the steel pipe (1); the toxic gas detection device (2) obtains the concentration of the gas samples, so that whether the adsorption medium reaches the 90-percent service life or not can be judged.

Description

technical field [0001] The invention belongs to the technical field of dry process special gas tail gas treatment, and in particular relates to an adsorption medium life indicator device for dry special gas tail gas treatment equipment. Background technique [0002] In the dry special gas tail gas treatment system, the adsorption medium is the core chemical reaction medium. The essence of special tail gas treatment is to have a chemical reaction with it to achieve the purpose of purification. Therefore, knowing when its life will end is the key to ensuring the normal operation of the system. necessary condition. [0003] At present, the judgment of the life of the adsorption medium is mainly based on the judgment method of color indication. The specific method is to set a transparent window at 90% of the medium container (that is, 90% of the adsorption medium), and a The connected cylindrical tanks are filled with color indicators. The working principle is that the color in...

AI Technical Summary

Problems solved by technology

[0005] 1. The connection between the window and the container needs to be sealed, and there is a risk of leakage;

[0006] 2. The color indicator is easily affected by the environment and the sensitivity changes, thus affecting its indicating function;

[0007] 3. This judgment method needs to be judged by naked eyes, that is, manual inspection is required, and the timeliness is very poor;

[0008] 4. Usually the position of the viewing window (at the bottom 10% of the media container) is very close to the ground, so it is easy to be polluted so that the internal situation cannot be observed well or frequent cleaning is required;

[0009] 5. When replacing or doing solid waste disposal, the window is easily damaged, which increases the cost of disposal / use;

[0010] 6. Generally, the indicator is relatively sensitive, and cannot reflect the real state of the exhaust gas when the color changes, that is, the concentration of the exhaust gas at this time cannot be known through it.
