[0002] Butadiene is an organic compound with the chemical formula C₄H₆. It is a colorless gas with a slight aromatic odor. It is insoluble in water, soluble in ethanol and methanol, and readily soluble in acetone, ether, and chloroform. It is a raw material for the manufacture of synthetic rubber, synthetic resin, and nylon. It is primarily produced by dehydrogenation of butane and butene, or by separation from C₄4 fractions. It has anesthetic properties, is particularly irritating to mucous membranes, and readily liquefies.
[0003] Butadiene extraction waste gas treatment equipment is an environmentally friendly device primarily used to treat waste gas generated during the butadiene extraction process, reducing environmental pollution.

A water inlet pipe 17 is connected to the spray port 16, and one end of the water inlet pipe 17 is connected to a pump 19. The front end of the water collecting tank 18 is connected to a drain pipe 24. The drain pipe 24 and one end of the pump 19 are connected to a treatment box 20, and a filter screen 21 is provided in the treatment box 20.
[0027] Preferably, an inspection door 4 is provided above the purification tower 2, and the inspection door 4 is located above the filler inlet and outlet 3. By providing the inspection door 4, it is convenient for maintenance personnel to inspect and maintain the interior of the purification tower 2, which increases the practicality and convenience of the device. A dust cover 7 is provided above the blower 6. By providing the dust cover 7, the blower 6 can be protected from dust. A connecting buckle 9 is provided on the outer wall of the air inlet pipe 8, and the connecting buckle 9 is provided in multiple groups. By providing the connecting buckle 9, the air inlet pipe 8 is conveniently connected to the butadiene production equipment.
[0028] Preferably, screw holes 14 are provided in the filter 11, the pressure plate 12 and the cover plate 13. There are multiple groups of screw holes 14, and bolts 15 are screwed into the screw holes 14. By setting the screw holes 14 and the bolts 15, the devices can be connected and fixed, which increases the intimacy and connectivity between the devices and ensures the safety of the devices during use. A limiting clamp 22 is installed on the filter 21, and the limiting clamp 22 is movably engaged with the processing box 20. By setting the limiting clamp 22, the filter 21 can be installed and fixed, which ensures the safety of the filter 21 during use and facilitates the user to disassemble and clean the filter 21 later.

By setting the overflow port 23, the staff can be reminded of the water level of the water collecting tank 18.
[0029] The use principle and use process of the present invention are as follows: when in use, the equipment that produces butadiene is connected, and the connection is made through the connecting buckle 9. After the docking is completed, the blower 6 is controlled to extract butadiene into the air inlet pipe 8. The butadiene entering the air inlet pipe 8 needs to be filtered through the filter screen 11 and then enter the connecting pipe 5, and then enter the purification tower 2 for purification through the connecting pipe 5. Water is needed to spray it during the purification process. When spraying, the pump 19 is turned on, and the pump 19 extracts the water in the treatment box 20 into the water inlet pipe 17, and then sprays it on the exhaust gas in the purification tower 2 through the spray port 16. The used water enters the water collecting box 18, and the exhaust gas after spraying is discharged through the demister above the purification tower 2. The water entering the water collecting box 18 enters the treatment box 20 through the drain pipe 24. The water entering the treatment box 20 needs to be filtered through the filter screen 21. After the filtration is completed, it is re-examined by the pump 19. The new water enters the water inlet pipe 17 for next use, and the used water can be filtered and reused, which realizes the recycling of water resources, increases the practicality and convenience of the device, and reduces the waste of water resources. When the filter 11 needs to be replaced, the air inlet pipe 8 is separated from the equipment that produces butadiene. After the separation is completed, the bolts 15 are rotated and removed from the screw holes 14 in turn with the help of tools. After removal, the cover 13 is removed from the air inlet pipe 8, and the pressure plate 12 is removed from the placement groove 10. After removal, the filter 11 is removed from the placement groove 10. After all are taken out, a new filter is placed in the placement groove 10, and the pressure plate 12 and the cover 13 are fixed in turn. The filter 11 in the device can be installed and disassembled, which extends the working time of the device, reduces the situation where impurities enter the device, and avoids the problem of inconvenient maintenance of the device in the later stage.
