Description

Technical Field

[0001] The utility model relates to the technical field of tail gas recovery, in particular to a tail gas recovery and treatment device coated with a polyester cloth surface PVC coating. Background Art

[0002] Polyester fiber, also known as polyester, is a synthetic fiber obtained by spinning polyester formed by the condensation of organic dibasic acids and diols. It is a high molecular compound.

[0003] When coating the polyester cloth with PVC coating, it is necessary to dry it to solidify the coating. This process will cause the volatilization of polluted gases. If not effectively treated, it will pollute the environment. Therefore, an exhaust gas recovery and treatment device for coating the polyester cloth with PVC coating is proposed.

[0008] Further, the processing structure includes a placement barrel, a positioning rod connected to the placement barrel is provided in the placement barrel, at least one filter screen plate is provided on the positioning rod and is set in an empty sleeve with the positioning rod, and a placement groove for placing filter materials for filtering exhaust gas is provided in the filter screen plate. The operation mode of the positioning rod and the filter screen plate is that the positioning rod is first installed in the placement barrel, and then three filter screen plates are placed in sequence, and after the first filter screen plate is placed, the filter screen plate is limited by the set limit nut to play a fixing role, and then the activated carbon fiber material can be placed in the placement groove of the first filter screen plate. After the placement is completed, the second filter screen plate is placed on the first filter screen plate, so that the second filter screen plate can limit the activated carbon fiber material in the placement groove of the first filter screen plate, and then the zeolite molecular sieve resin synthetic material is placed in the placement groove of the second filter screen plate, and then the third filter screen plate is placed. The function of the third filter screen plate is the same as that of the second filter screen plate, but a water-absorbing sponge can be placed on the placement groove of the third filter screen plate. Due to the unbalanced and unsaturated molecular attraction or chemical force on the solid surface of activated carbon, when the solid surface comes into contact with gas, it can attract gas molecules, causing them to concentrate and remain on the solid surface, thereby adsorbing the pollutants.

[0009] Furthermore, the positioning rod is provided with three filter screen plates which are hollowly sleeved with the positioning rod, and the positioning rod is provided with a limiting nut for limiting and locking the filter screen plates.

[0010] Furthermore, the cross-section of the placement bucket is in a trumpet shape, and an air outlet is provided at the bottom end of the trumpet-shaped placement bucket.

[0011] Furthermore, the surface of the filter screen is provided with a plurality of connecting blocks connected to the filter screen, the barrel wall of the connecting barrel is provided with a slide groove corresponding to the connecting block, the three filter screens are arranged in sequence from top to bottom, the aperture number of the filter screen is between 100 mesh and 140 mesh, and the diameter of the air outlet at the bottom end of the trumpet-shaped placement barrel is smaller than the diameter of the air inlet at the top end of the placement barrel.

[0012] Furthermore, a sealing plate for sealing the cavity is provided at the bottom end of the placement rack.

[0013] Furthermore, the recovery structure includes a connecting pipe connected to the placement rack, the air inlet end of the connecting pipe is connected to the placement bucket, and the air outlet end of the connecting pipe is provided with a negative pressure fan connected to the connecting pipe.

[0014] Furthermore, the negative pressure fan is arranged above the connecting pipe, and the air outlet end of the negative pressure fan is provided with an air outlet pipe connected to the negative pressure fan.

[0015] Furthermore, the upper end of the connecting barrel is provided with a conical cover connected to the connecting barrel, the conical cover is provided with an air intake pipe connected to the cavity, and the air intake end of the air intake pipe is provided with an air collecting pipe connected to the air intake pipe.

[0016] Furthermore, the cross-sectional shape of the gas collecting pipe is trumpet-shaped, and the diameter of the air inlet end face of the trumpet-shaped gas collecting pipe is larger than the diameter of the air outlet end face of the gas collecting pipe.

[0017] Compared with the prior art, the tail gas recovery and treatment device for coating the polyester cloth with PVC coating can timely recover and treat the tail gas when the polyester cloth is coated with PVC coating, thereby avoiding pollution to the environment, through the coordinated arrangement of the treatment structure and the recovery structure.
