Background
The large air volume and low concentration industrial VOCs mostly adopt a treatment process combining adsorption concentration and combustion.
The adsorbent is usually activated carbon in the adsorption and concentration process, and after the activated carbon is saturated in adsorption, the activated carbon is combusted after being subjected to desorption and concentration by water vapor or nitrogen. The nitrogen gas as desorption medium has high operation cost, the water vapor as desorption medium generates waste water in the desorption process, secondary pollution is caused, and after the desorption is finished, the activated carbon can be reused after being cooled and dried for a long time.
The combustion method is mainly classified into direct combustion (TO), catalytic Combustion (CO), regenerative combustion (RTO), and regenerative catalytic combustion (RCO).

Dioxins are mainly by-products of industrial processes, but may also originate from natural processes, such as volcanic eruptions and forest fires. Dioxins are harmful by-products of various production processes such as smelting, pulp chlorine bleaching and the manufacture of some herbicides and pesticides. The main cause of dioxin production is insufficient combustion.
The greatest harm of dioxins is irreversible "tri-carcinogenic" toxicity, i.e. teratogenic, carcinogenic, mutagenic. May cause death of the fetus in the early development stage, destruction of the organ structure and permanent damage to the organ, or developmental retardation, reproductive defects; it can interfere the hormone secretion of the reproductive system and the endocrine system to cause the reduction of sperm count, the reduction of sperm quality, the interruption of testicular development, permanent sexual dysfunction, the self-cognition disorder of sex, and the like of men; causing female uterine cancer deformity, breast cancer and the like; permanent impairment of the children's immune, mental and motor abilities may also result, such as hyperactivity disorder, dementia, hypoimmunity, etc.

the utility model discloses during the use, including absorption and desorption process, including following step:
adsorption step

and step 3: an induced draft fan is arranged in the adsorption gas outlet pipe to start to guide the adsorbed waste gas into an exhaust funnel and finally into the external atmospheric environment until the activated carbon in the activated carbon box is saturated;

step 2: external air is introduced through an air inlet of the heat exchanger and is introduced into the activated carbon box in a saturated state through a desorption air inlet end;
and step 3: leading the waste gas desorbed from the activated carbon box into an NRJ-V internal combustion type burner for combustion;
and 4, step 4: NRJ-V internal combustion type burner sequentially performs air suction, compression, energy production and exhaust strokes, NRJ-V internal combustion type burner does work outwards, and the burnt tail gas is discharged; in the air suction stroke in the step 4 of the desorption step, the desorption step is divided into three stages according to the concentration of VOCs, wherein the three stages are respectively an initial stage, a middle stage and a final stage; the VOCs concentration in the initial stage and the middle stage is high, and external combustible gas is not required to be introduced; the low concentration of VOCs in the end stage requires the introduction of external combustible gas as energy supplement.
Suction stroke: the piston is driven by the crankshaft to move from the top dead center to the bottom dead center. At this time, the intake valve is opened, the exhaust valve is closed, and the crankshaft is rotated 180 °. In the moving process of the piston, the volume of the cylinder is gradually increased, the gas pressure in the cylinder is gradually reduced, a certain vacuum degree is formed in the cylinder, and the waste gas is sucked into the cylinder through the inlet valve and further mixed in the cylinder to form combustible mixed gas. Because of the resistance of the air intake system, the air pressure in the cylinder is lower than the atmospheric pressure. The temperature of the combustible mixture entering the cylinder rises due to the heating of high temperature parts such as the intake pipe, the cylinder wall, the piston crown, the valve and the combustion chamber wall and the mixing with the residual exhaust gas. The organic waste gas enters an NRJ-V internal combustion engine and is divided into three stages according to the concentration of the waste gas:
firstly, the initial section is about 88 minutes, the concentration of VOCs is high, the air extraction amount of the section is controlled at a low level, and additional energy is not required to be supplemented;
the middle section is about 44 minutes, the air extraction amount of the section is increased in the concentration of VOCs, and additional energy is not required to be supplemented;
and thirdly, the concentration of VOCs is low in the last section of about 12 minutes, the air extraction amount of the section is further improved, and only little energy needs to be supplemented.
(2) Compression stroke: during the compression stroke, the intake and exhaust valves are closed simultaneously. The piston moves from the bottom dead center to the top dead center, and the crankshaft rotates 180 degrees. When the piston moves upwards, the working volume is gradually reduced, and the pressure and the temperature of the mixed gas in the cylinder are continuously increased after the mixed gas is compressed, so that the compression end point is reached.
(3) Capacity producing stroke: in the capacity producing stroke, the air inlet valve and the exhaust valve are both closed, and the crankshaft rotates 180 degrees. When the piston is close to the top dead center, the spark plug ignites the combustible mixture, and the mixture is combusted to release a large amount of heat energy, so that the pressure and the temperature of the gas in the cylinder are rapidly increased. The high-temperature and high-pressure gas pushes the piston to move from the top dead center to the bottom dead center, and mechanical energy is output outwards through the crank-link mechanism. As the piston moves down, the cylinder volume increases and the gas pressure and temperature gradually decrease.
(4) Exhaust stroke: during the exhaust stroke, the exhaust valve is opened, the intake valve is still closed, the piston moves from the bottom dead center to the top dead center, and the crankshaft rotates 180 degrees. When the exhaust valve is opened, the burnt waste gas is discharged out of the cylinder under the action of the pressure difference between the inside and the outside of the cylinder on one hand, and is discharged out of the cylinder on the other hand through the extrusion action of the piston. The pressure at the end of the exhaust is slightly above atmospheric pressure due to the resistance of the exhaust system. When the piston moves to the upper dead point, a working cycle is completed.
And 5: the exhausted tail gas is led into a heat pipe of the heat exchanger, preheated by heat exchange with a cold pipe, led into an exhaust funnel and finally led into the external atmospheric environment.
