Description

TECHNICAL FIELD

[0001] The utility model relates to white primer processing technical field, especially a kind of condensation reflux column for white primer processing. BACKGROUND

[0002] The condensation reflux column for white primer processing is a device specially used for solvent recovery and waste gas treatment in the production process of paint. It plays a key role in the production of white primer (a primer commonly used in the furniture, automobile and other industries), mainly used for condensation and recovery of volatile organic compounds (VOCs), to reduce environmental pollution and improve resource utilization.

[0003] At present, after condensation treatment, the gas continues to rise in the tower, and the residual VOCs concentration has been greatly reduced after the condensation section. However, when these gases are discharged from the top of the condensation reflux column, although the toxic odor in the gas has been greatly reduced after condensation treatment, there may still be a small amount of toxic medium, which has a certain impact on environmental protection. In addition, when the waste gas enters the condensation reflux column, its temperature is often difficult to accurately control. When the waste gas temperature is low, the condenser needs to consume more cooling medium (such as water or refrigerant) to reach the target temperature, which not only increases the operating cost, but also reduces the energy efficiency. At the same time, the cooling effect of low-temperature waste gas in the condenser is uneven, which may cause part of the solvent to fail to be fully condensed and recovered, further affecting resource utilization and environmental protection effect.

[0033] Reference Figs. 1-5 This is the second embodiment of the utility model, which is based on the previous embodiment.

[0034] Specifically, the top of the feeding shell 3 is fixedly connected with a heating device 13, and the bottom of the heating device 13 is fixedly connected with a heat-conducting copper pipe 14 penetrating into the inside of the feeding shell 3.

[0042] Specifically, one side of the bottom of the inner cavity of the cooling tower 1 is fixedly connected with a flow guide plate 20, and the inside of the connecting plate 18 is arrayed with leakage grooves 21.

[0043] The flow guide plate 20 is convenient for guiding the gas into the inside of the cooling tower 1, and the leakage grooves 21 are arrayed in the inside of the connecting plate 18, so that the backflow of the liquid solvent can be discharged to the bottom of the cooling tower 1.

[0044] Embodiment 3

[0046] Specifically, the fixed plate 1201 is fixed to the front side of the exhaust shell 6, the first plug plate 1202 and the second plug plate 1203 are respectively fixed to one side of the filter shell 1103 and the filter plate 1104, the two sides of the fixed plate 1201 are fixedly connected with springs 1204, and one end of each spring 1204 is fixedly connected with a plug rod ring 1205.

[0047] When the user needs to disassemble the filter shell 1103 and the filter plate 1104, the insertion rod ring 1205 can be moved relatively, and as the insertion rod ring 1205 moves, the spring 1204 is compressed and synchronously separated from the inside of the first insertion plate 1202 and the second insertion plate 1203, and then the filter shell 1103 and the filter plate 1104 can be disassembled and cleaned respectively.

[0048] Specifically, the insertion rod ring 1205 is slidably connected with the limiting column 1206 inside, one end of the limiting column 1206 is fixedly connected with the fixed plate 1201, and the other side of the limiting column 1206 is fixedly connected with the retaining plate 1207, one side of the retaining plate 1207 is fixedly connected with the exhaust shell 6.

[0049] Through the fixation of the limiting column 1206 and the retaining plate 1207, and the surface sliding of the insertion rod ring 1205 and the limiting column 1206, the stability of the insertion rod ring 1205 during movement can be improved. It should be noted that the insertion rod ring 1205 is provided with a slot that matches the limiting column 1206, and the distance of the insertion rod ring 1205 when it is separated from the first insertion plate 1202 and the second insertion plate 1203 is sufficient and will not limit the insertion rod ring 1205.

[0050] In use, first, the user can guide the white primer waste through the feed pipe 4 into the feed shell 3, and then heat the heat-conducting copper pipe 14 through the heating device 13 to preheat the exhaust gas, reduce external energy consumption, and cool the exhaust gas to the target temperature through the condenser, reducing the amount of cooling medium used. Then, the second fan 19 is conveniently fixed through the connecting plate 18, and the connecting plate 18 can have a certain flow resistance effect on the gas just sucked into the cooling tower 1, so that the gas can be preheated in the heat-conducting copper pipe 14. When preheating is completed, the second fan 19 can be opened to suck the gas into the middle of the cooling tower 1, cooperate with the multiple condensing pipes 8 to cool, and the preheated exhaust gas is more easily uniformly cooled in the condenser to avoid local overcooling or icing. Then, the condensate is conveniently guided into the inside of the condensing pipe 8 through the liquid guide shell 7, the liquid inlet pipe 9 and the liquid outlet pipe 10, and the condensing pipe 8 is arranged in a U-shaped array to significantly increase the cooling area and improve the condensing efficiency. The heat-exchanged liquid is discharged through the liquid outlet pipe 10 and enters the circulation system to realize efficient use of resources. Then, the heated liquid is discharged through the liquid outlet pipe 10 for recycling. Then, the first fan 1102 is opened, the exhaust gas is filtered through the filter plate 1104 in the exhaust shell 6, and then purified through the activated carbon medium in the filter shell 1103, so as to further adsorb harmful substances and ensure that the discharged gas meets environmental protection standards. Then, the returned liquid solvent flows to the bottom of the cooling tower 1 through the leakage groove 21 in the connecting plate 18, and is discharged through the discharge pipe 5.
