Background
The current methods for treating VOCs (volatile organic compounds) are various: heat accumulating type incineration, an adsorption concentration thermal oxidation technology, an adsorption recovery purification technology, a microorganism purification technology and the like.
The existing VOCs concentration thermal oxidation all-in-one machine adopts an adsorption concentration thermal oxidation technology, and the specific structure of the all-in-one machine comprises a pretreatment module, a runner module, a catalytic thermal oxidation module, a desorption wind heat air pipeline, a concentration wind pipeline and a cooling wind pipeline;

the chemical thermal oxidation module comprises a purified air circulation pipe, a gas-gas heat exchanger, a desorption fan, a hot bypass pipeline, a catalysis removal chamber heating electric heater, a catalysis chamber, a desorption air heating electric heater and an air mixing box;
the working principle is as follows: organic waste gas is sent into the rotating wheel through the fan from the entering equipment through the four-layer filter (G4.F7.F9. active carbon), and when volatile organic gas passes through the hydrophobic zeolite concentration rotating wheel, organic matters can be effectively adsorbed in zeolite, so that the purpose of removing the organic gas is achieved. The clean gas, which has been subjected to zeolite adsorption of volatile organic compounds, is discharged into a stack (stack not shown) via a cleaned air outlet. The wheel continues to rotate at 1-6 revolutions per hour while the adsorbed volatile organic is transferred to the desorption zone. In the desorption area, volatile organic compounds are desorbed by the heating gas from the desorption air pipe, so that concentrated organic compound gas is formed and is conveyed away by a concentration pipeline. The concentrated gas conveyed by the concentrated pipeline is sent to the cold end of the heat exchanger for primary heating through the desorption fan. The temperature of the concentrated gas from the heat exchanger is heated to about 220 ℃, and the concentrated gas is heated again by the main electric heater for the second time, so that the temperature reaches over 300 ℃, and the temperature of the gas reaches the temperature required by catalysis. The hot exhaust gas enters the catalytic chamber from the catalytic chamber inlet to be subjected to thermal oxidation treatment, so that CO2 and H2O are generated, and a large amount of heat is generated. The purified air and heat after catalysis flow out from the outlet of the catalysis chamber and enter the hot end of the heat exchanger to carry out primary heating of waste gas, and the purified waste gas flows out from the outlet of the heat exchanger and then is converged into the purified air outlet to be discharged into a chimney and then is discharged into the atmosphere;
if the temperature in the catalytic chamber is over 450 ℃, the purified waste gas and heat flowing out of the outlet of the catalytic chamber directly converge into the purified air outlet through the hot bypass pipeline and are discharged into a chimney and then into the atmosphere;
one path of cooling air flowing out of the rotating wheel flows into the air mixing box through the cooling air pipe. A small stream of high-temperature hot gas is taken from the outlet of the heat exchanger and flows into the air mixing box through the heat taking pipe. The hot air and the cold air are uniformly mixed by the air mixing box and then enter the desorption air heating electric heater for heating, the temperature is heated to about 200 ℃, and then the hot air and the cold air are sent into the rotating wheel for desorption through the desorption air heating pipeline, so that the concentrated air enters the concentrated air pipeline, and the reciprocating circulation is carried out.
If the exhaust inlet is closed before the exhaust line has been connected to the plant, the fresh air port is opened and air enters the plant from there, thus supporting the whole intake cycle before the plant is started.
Whole system assembles according to the concentrated thermal oxidation all-in-one of VOCs when assembling to make the all great of off-the-shelf volume, and when the transport, need carry each module one by one, assemble again after the mill, waste time and energy.
