Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a waste gas recovery condenser. Background Art

[0002] The condensation recovery method is widely used in the treatment of valuable VOCs waste gas. However, in many current VOCs waste gas condensation recovery devices, the cold medium is set outside the fine pipe or channel. The VOCs waste gas passes through the fine pipe or channel, and the VOCs waste gas is condensed by heat transfer in the fine pipe or channel. The heat transfer effect of the fine pipe or channel is not ideal, resulting in a low condensation recovery rate of VOCs, which causes the VOCs emission limit of the tail gas to fail to meet the emission standards.

[0025] In this embodiment, the mesh heat exchange structure can exchange heat with the heat exchange plate 402 when the exhaust gas passes through the mesh, thereby improving the heat exchange effect of the exhaust gas.

[0026] Example 2

[0027] like Figure 1-3 As shown, on the basis of Example 1, the utility model provides a technical solution: the liquid discharge mechanism 5 includes a water storage tank 501, a drain pipe 502 and a solenoid valve 503, the water storage tank 501 is opened at the bottom end of the shell 1, the drain pipe 502 is arranged at the bottom end of the water storage tank 501, and the solenoid valve 503 is arranged on the drain pipe 502; the mist shower mechanism 6 includes a liquid pump 601, a connecting pipe 602 and a mist shower nozzle 603, the liquid pump 601 is arranged on the inner wall of the shell 1, the connecting pipe 602 is arranged at both ends of the liquid pump 601, the end of the connecting pipe 602 is arranged inside the water storage tank 501, and the mist shower nozzle 603 is arranged at one end inside the shell 1; the connecting pipe 602 is fixedly arranged on one side edge of the heat exchange plate 402, the mist shower nozzle 603 is arranged around the side of the air inlet pipe 2, and the end of the mist shower nozzle 603 is inclined inwardly; the condensation mechanism 4 also includes an isolation net 403, the isolation net 403 is arranged at the top of the water storage tank 501, and the isolation net 403 is fixedly connected to the heat exchange plate 402;

[0028] In this embodiment, the mist shower mechanism 6 can be set up to spray the water in the water storage tank 501 through the mist shower nozzle 603 to the exhaust gas entering the inner part of the shell 1 through the air intake pipe 2. The atomized water vapor can reduce the temperature of the exhaust gas after mixing with the exhaust gas, thereby further improving the condensation effect of the exhaust gas.

[0029] The following is a detailed description of the working principle of this exhaust gas recovery condenser.

[0030] like Figure 1-3As shown, when in use, the exhaust gas is introduced into the housing 1 from the air inlet pipe 2, and the liquid pump 601 and the heat exchanger 401 are started at the same time. The heat exchanger 401 cools the heat exchange plate 402. At the same time, the water introduced from the water storage tank 501 by the liquid pump 601 passes through the connecting pipe 602, and the connecting pipe 602 connected to the heat exchange plate 402 cools the water inside. At the same time, the liquid pump 601 transports the water to the mist shower nozzle 603, and the mist shower nozzle 603 tilted inward sprays the atomized water vapor to the air inlet. The exhaust gas entering from the air pipe 2 is mixed with the exhaust gas, and the mixed gas moves toward the heat exchange plate 402 and exchanges heat with the heat exchange plate 402 when passing through the mesh of the heat exchange plate 402. The exhaust gas condenses and drips downward, and the dripping liquid passes through the isolation net 403 and flows into the water storage tank 501 for subsequent circulation operations. At the same time, after the exhaust gas condensation operation is completed, the drain pipe 502 can be opened through the solenoid valve 503 to replace the waste water in the water storage tank 501.
