Problems solved by technology

Traditional exhaust gas purification devices mainly use activated carbon for adsorption. Activated carbon purification is a physical process. The exhaust gas that only passes through activated carbon also contains some impurities and dust. The purification effect is not ideal, and in order to reduce the diffusion of harmful gases, it is necessary to use chemical methods for purification At present, there are chemical absorption method, catalytic combustion method, plasma purification method, etc., these methods are relatively single, and cannot fully achieve the purification effect

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 The exhaust gas purification system includes a water tank 4 and an oxidation tank 7 containing an oxidant. The water tank 4 is provided with a first air inlet pipe 1 and a first air outlet pipe 3. The first air inlet pipe 1 is inserted into the liquid surface in the water tank 4. Below, the first air outlet pipe 3 is positioned at the top of the water tank 4; the oxidation box 7 is provided with a second air inlet pipe 6 and a second air outlet pipe 8, and the second air inlet pipe 6 is inserted below the liquid level of the oxidation box 7, and the second air outlet pipe 8 is located at the top of the oxidation box 7, the first outlet pipe 3 communicates with the second inlet pipe 6, and the second outlet pipe 8 is connected with a concentration measurement device 10 for measuring the concentration of harmful gases in the exhaust gas. The ou...

Abstract

The invention relates to a waste gas purification system. The waste gas purification system comprises a water tank and an oxidation tank filled with oxidizing agents, wherein a first gas inlet pipe and a first gas outlet pipe are arranged on the water tank; a second gas inlet pipe and a second gas outlet pipe are arranged on the oxidation tank; the first gas outlet pipe is communicated with the second gas inlet pipe; a concentration determination device which is used for determining the concentration of harmful gas in waste gas is connected to the second gas outlet pipe; a three-way flow divider valve is arranged at an outlet of the concentration determination device; a flow divider port of the three-way flow divider valve is connected with the second gas inlet pipe, and another flow divider port of the three-way flow divider valve serves as a gas exhaust port of the whole system. The concentration of the harmful gas is tested, and the three-way flow divider valve is controlled according to a test result; when the concentration is in accordance with an environmental protection emission standard, the harmful gas can be directly emitted; when the concentration exceeds the standard, the harmful gas enters the oxidation tank through a pipeline for re-purification; the whole system can be used for effectively treating various harmful substances such as dust, sulfide and nitrogen oxide contained in the waste gas and peculiar smell in the waste gas; the emitted gas no longer pollutes the environment.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an exhaust gas purification system. Background technique [0002] Exhaust gas purification mainly refers to the work of treating industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. Exhaust gas purification equipment is widely used in chemical factories, electronics factories, painting factories, automobile factories, paint factories, petrochemical industries, furniture factories, food factories, rubber factories, plastic factories and other industries that produce odor, odor, and toxic and harmful gases. Traditional exhaust gas p...
