In this way, the entire desorption zone 6 can be desorbed), and a control box 7 is also provided in the housing 1.

The heat pipe 321 and the piping system 5 are electrically connected. The advantage of the utility model is that the voc particles on the carbon plate are desorbed and burned. There will be dust removal equipment in some production workshops, and the dust here includes dust and voc particles. Therefore, when the dust in the dust removal equipment is collected, the voc particles on the adsorption carbon plate will not fall, so it needs to be desorbed and burned. When the workshop workers get off work, put the carbon plate full of voc particles into the rack 61 , Turn on the equipment and start operation, just after adjusting the time, the equipment can work offline after workers are off work, and the equipment is integrated, which is convenient for transportation and takes up a small area.

As shown in 6, the heat exchange device 41 includes a heat exchange part 411 and a plurality of heat exchange covers 422. The heat exchange covers 422 are divided into two ends of the heat exchange part 411, and both ends of the heat exchange cover 422 are provided with air inlets 9 And the air outlet 10 (the heat exchange cover 422 on one side is in communication with the heating chamber 32, the air inlet of the channel through which the heated air flows out is on the upper part of the left heat exchange cover 422, and the voc particles are desorbed and recycled back to the cooled air flow The air outlet of the inlet channel is at the lower part of the left heat exchange cover 422), the heat exchange part 411 is composed of multiple heat exchange plates (the heat exchange plate 61 is made of stainless steel), and there are several barrier groups 11 on the heat exchange plate. , The barrier group 11 includes a protruding part 111 and a recessed part 112 (the barrier group 11 in the present utility model is integrally formed, directly pressed by the machine mold so that the front side of the heat exchange plate has a protruding part 111, and the reverse side is a recessed part 112 or The front side of the heat exchange plate is the recessed part 112 and the reverse side is the protruding part 111), the protruding part 111 and recessed part 112 of each barrier group 11 correspond to each other, and the protruding part 111 and recessed part 112 are parallel to each other on the adjacent barrier group 11 And the vertical arrangement (here refers to the two adjacent barrier groups 11 on the front side of the heat exchange plate, one is a protruding part 111 and the other is a recessed part 112, the same from the reverse side, one is a recessed part 112 and the other is a protrusion Part 111, and the two are parallel to each other and are vertically arranged on the heat exchange plate), the heat exchange plate in the present invention is divided into two parts, the upper part of the barrier group 11 and the lower part of the barrier group 11 are butted on On a straight line and on the same plane, the upper part of the barrier group 11 is a recessed part 112, then the lower part of the barrier group 11 is a protruding part 111, or the upper part of the barrier group 11 is a protruding part 111, the lower part of the barrier Group 11 is a recessed portion 112. When any two heat exchange plates are stacked, the recessed portions 112 on the two heat exchange plates are superimposed on each other to form a ventilation gap for air circulation. Each protrusion on the two heat exchange plates The parts 111 are superimposed on each other to form a barrier rib that obstructs air circulation. A reheating zone 12 is formed between two adjacent barrier groups 11. The ventilation gap and the reheating zone 12 are connected to form a ventilation channel. When the three heat exchange plates are stacked At the same time, the ventilation channel formed between the middle heat exchange plate and the left heat exchange plate is the channel through which the heated air flows out, and the ventilation channel formed between the middle heat exchange plate and the right heat exchange plate In order to recover the air flow into the channel after desorption of the voc particles, the paths of the outflow channel and the flow channel are staggered but do not affect each other, because the heat exchange plate is divided into the upper part and the lower part by two sets of barrier groups 11 ), this setting here is mainly to increase the distance of the ventilation channel, so that the heating of the recovered air is more efficient, the heated air can store the temperature of the heat exchange plate more efficiently, reduce the heating time of the heating tube 321, and reduce energy consumption.

As shown in 2, the desorption pipe 51 is also provided with a cooler 13 communicating with the desorption pipe 51, and the cooler 13 delivers cold air to the desorption pipe 51 to neutralize the hot air in the desorption pipe 51 ( The air cooler 13 transports the cold air through the desorption pipe 51 to the desorption box for cooling, where the cooling is mainly used to quickly cool the desorbed carbon plate. Secondly, the hot air in the desorption pipe 51 is neutralized. When the temperature is lowered, if the temperature of the high-temperature air flowing out of the heat exchange device 41 becomes too high, the carbon plate is likely to burn).

When the high-temperature air flow in the heat exchange zone 4 passes through the desorption pipe 51, the The three-way control valve 2 closes the end of the flow to the desorption zone 6 and opens the connecting pipe 14. Once again, the desorption zone 6 has already started to desorb, and the voc particles after desorption flow to the recovery pipe 52. At this time, the high temperature air flow is The connecting pipe 14 flows, to the desorption zone 6

The air flow with voc particles flowing to the recovery pipe 52 is heated.

29.

A certain amount of heat is available for subsequent use). When the temperature in the desorption zone 6 reaches 90 degree , the voc particles adsorbed on the carbon plate begin to desorb (here the blower 54 is stopped, and the recovery pipe 52 is also closed. ), the desorbed voc particles follow the work of the blower 54 and return to the heat exchange device 41. The recovered gas with the voc particles is initially heated to a certain temperature through the heat exchange device 41 (the temperature decreases during the recycling process), Then enter the heating chamber 32. Since the heating temperature of the heating tube 321 is about 350 degree , under the catalysis of the precious metal catalyst plate 311, the voc particles can be burned at 350 degree .
