Problems solved by technology

[0003] Among many pollution sources, the VOCs from industrial production are huge and the treatment effect on them is poor. The conventional plasma method currently used in the market is used for treatment, and the treatment rate of harmful molecules in the exhaust gas is low, not long-term and safe. Sex is not high

Embodiment 1

[0033] according to figure 1A double-three plasma exhaust gas treatment process shown includes an exhaust gas treatment device 1, the exhaust gas treatment device 1 includes a box body 2, and the box body 2 is provided with an air inlet 3 on one side and an air outlet on the other side 4. The inside of the box 2 is provided with a pre-processing module 5, a plasma module 6 and a post-processing module 7 arranged in sequence from left to right, and the plasma module 6 includes a first module 8 arranged in sequence from left to right , an intermediate module 9 and a second module 10, the pretreatment module 5 and the posttreatment module 7 all include a frame 24 and a volcanic rock filler 11, the frame 24 is made of SUS304 material, and the volcanic rock filler 11 is arranged on the inside of the frame 24 , the volcanic rock filler 11 is provided with honeycomb holes, and the dust removal effect is good. Both sides and the top of the pretreatment module 5 and the posttreatment m...

Embodiment 2

[0038] The present invention also provides a double-three plasma waste gas treatment process, the specific steps of the waste gas treatment process are as follows:

[0039] Step 1: Exhaust gas pretreatment, the exhaust gas is drawn into the interior of the box body 2 through the air inlet 3 by the induced draft fan, and the exhaust gas is initially filtered through the volcanic rock filler 11 on the pretreatment module 5, which can effectively absorb dust particles in the exhaust gas, thereby further To ensure the long-term efficient and stable operation of the plasma module 6 on the rear side, the waste gas can also be sucked in from the air outlet 4 for waste gas treatment and then discharged from the air inlet 3;

[0040] Step 2: double-three plasma exhaust gas treatment, powering the plasma module 6 through the adaptive power supply 15, forming a fan-shaped plasma field by the second line structure electrode 17 and a plurality of needle-point electrodes 18 on both sides, fo...

Abstract

The invention discloses a double-triple plasma waste gas treatment process, which comprises a waste gas treatment device, wherein the waste gas treatment device comprises a box body, a wind inlet is formed in one side of the box body, a wind outlet is formed in the other side of the box body, a pretreatment module, a plasma module and a post-treatment module are sequentially arranged in the box body from left to right, the plasma module comprises a first module, a middle module and a second module, the first module, the middle module and the second module are sequentially arranged from left toright, the pretreatment module and the post-treatment module respectively comprise a frame and a volcanic rock filler, spraying pipes are arranged on the two sides and the tops of the pretreatment module and the post-treatment module, and spraying heads are arranged on the spraying pipes. According to the invention, a second line structure electrode and a plurality of needle tip electrodes on thetwo sides form a plasma field with a sector structure to form a discharge mode consisting of plasma structure parameters such as points, lines and surfaces, so that particles in waste gas are destroyed by the whole discharge structure instead of adsorption, the dust removal efficiency is high, and the use is long-acting and safe.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a dual-three plasma waste gas treatment process. Background technique [0002] VOCs volatile organic compounds refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or all organic compounds with corresponding volatility at a vapor pressure greater than or equal to 10Pa at 20°C. Sources of VOCs Extensive, the main sources of pollution include industrial sources, domestic sources, industrial sources mainly include petroleum refining and petrochemical, coal processing and conversion and other production industries containing VOCs raw materials, oil (fuel, solvent, etc.) storage, transportation and sales process, paint , ink, adhesives, pesticides and other production industries that use VOCs as raw materials, and the use process of products containing VOCs such as painting, printing, b...
