It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1 - 7 , the present utility model provides a technical solution: a condensation device, including a box body 1, an air inlet pipe 2 is arranged on one side of the box body 1, an air outlet pipe 3 is arranged on the other side of the box body 1, an exhaust hole 8 communicating with the air outlet pipe 3 is arranged on the box body 1, a condensation component is arranged inside the box body 1, the lower end of the condensation component communicates with the air inlet pipe 2, the upper end of the condensation component communicates with the exhaust hole 8, and a vertical pipe 13 is arranged on the inner wall of the upper end, a piston rod 16 is vertically arranged in the vertical pipe 13, a baffle 10 rotatably and elastically installed is arranged on the exhaust hole 8, a lever 12 rotatably installed is arranged inside the upper end of the box body 1, one end of the lever 12 presses on the piston rod 16, a driving member 17 pressing on the baffle 10 is arranged at the other end of the lever 12, and a return groove 9 communicating with the lower end of the condensation component is arranged at the upper end of the exhaust hole 8.

[0026] By setting the piston rod 16, the lever 12, the driving member 17 and the baffle 10, when the VOCs gas is not completely condensed, an upward force is applied to the piston rod 16, and the force is transmitted through the lever 12 to make the driving member 17 press down the baffle 10 to block the exhaust hole 8. By setting the return groove 9, the uncondensed waste gas is re-condensed.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, a drain pipe 4 is arranged at the lower end of the box body 1, partition plates 6 are arranged on the inner side wall of the box body 1 in a staggered and inclined arrangement, a condensation circulator 5 is arranged on the outer side wall of the box body 1, condensation pipes 7 communicating with the condensation circulator 5 are arranged under the partition plates 6, the condensation component includes the partition plates 6 and the condensation pipes 7, and there is a gap between the condensation component and the inner wall of the box body 1.

[0029] By setting the partition plates 6 and the condensation pipes 7 arranged in a staggered and inclined manner, the waste gas can fully contact with the condensation pipes 7 in the inner cavity of the box body 1. At the same time, the inclined installation of the partition plates 6 facilitates the condensed VOCs liquid to flow to the drain pipe 4.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, one side of the baffle 10 close to the air outlet pipe 3 is rotatably mounted on the box body 1. A spring 11 connecting the box body 1 is arranged at the upper end of the baffle 10. A circular piston cover 14 is mounted at the lower end of the vertical pipe 13. A piston 15 connected to the piston rod 16 is arranged on the piston cover 14. The inner diameter of the piston cover 14 is smaller than the diameter of the piston 15. The driving member 17 is a flexible member, and a weight 18 pressing on the baffle 10 is arranged at the lower end of the driving member 17.

[0032] By providing the flexible driving member 17, interference with the driving member 17 during the rotation of the lever 12 is avoided.

[0033] A VOCs waste gas treatment device includes the above-mentioned condensation device.

[0034] During actual use, the VOCs waste gas enters the box body 1 through the air inlet pipe 2, rises along the alternately arranged and obliquely installed partition plates 6 and condensation pipes 7 and fully contacts the condensation pipes 7. The VOCs condense into a liquid and separate from the gas and flow to the drain pipe 4. When the waste gas inside the box body 1 is not completely condensed, the gas pushes the piston 15 in the vertical pipe 13 to rise, driving the piston rod 16 to rise, thereby lifting one side of the lever 12. The other side of the lever 12 is stressed, causing the weight 18 to press down the baffle 10 to block the exhaust hole 8. The gas flows to the lower end of the condensation assembly along the return groove 9 and is condensed again. When the gas is completely condensed, the lever 12 no longer exerts a downward pressure on the baffle 10. The baffle 10 is pulled by the spring 11, causing the exhaust hole 8 to communicate with the air outlet pipe 3 to discharge the gas.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
