Description

Technical Field

[0001] The utility model relates to the technical field of cresol production equipment, in particular to a cresol production gas-liquid separation device. Background Art

[0002] In the production process of cresol, when the sodium cresol alkali fusible solution produced by the alkali fusion process undergoes an acidification process and undergoes an acidification reaction to generate acidic cresol, phenolic gas and residual sulfur dioxide gas used for acidification will overflow through the venting phase of various equipment and storage tanks and emanate into the atmosphere, with a strong odor, causing pollution to the surrounding environment and affecting the lives of surrounding residents. At the same time, sulfur dioxide gas also causes corrosion to the equipment and pipelines in the production workshop, greatly affecting the service life of the equipment and pipelines. At the same time, since the gas generated by the sodium cresol alkali fusible solution in the acidification process contains an atomized solution, it contains part of the cresol solution. If it is not collected and recycled, it will cause a waste of production raw materials and increase production costs. During the existing gas-liquid separation, due to the low proportion of the atomized solution in the gas, the position of the drain port remains open, so part of the gas will overflow, causing environmental pollution. At the same time, the atomized solution is difficult to be more thoroughly adsorbed and settled inside the separation device. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a cresol production gas-liquid separation device, which can quickly and effectively separate the cresol solution in the gas, reduce the waste of raw materials, reduce production costs, and no harmful gases will leak during the separation process, thus having good environmental protection.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a gas-liquid separation device for cresol production, comprising a separation tank, the separation tank being provided with an air inlet and an air outlet, a liquid discharge port being provided at the bottom of the separation tank, the air inlet being arranged along the tangent direction of the separation tank, and also comprising a liquid discharge pipe connected to the liquid discharge port, and the liquid discharge pipe being provided with an anti-overgas structure, and also comprising a collecting component, the collecting component comprising an adsorption net located inside the separation tank, and the adsorption net being located between the air inlet and the air outlet, and also comprising a driving component for driving the adsorption net to rotate, and the air outlet being located on a side of the separation tank away from the air inlet.

[0005] After the gas to be treated is introduced into the air inlet pipe through the air pump, the high-speed air flow will rotate at high speed inside the separation tank, and the atomized cresol solution in the gas will be separated to the inner wall of the separation tank by centrifugal force. When the gas passes through the adsorption net, the solution contained in the gas will be adsorbed again under the action of the adsorption net to achieve a higher separation effect of the gas containing the atomized solution. The gas that has passed the adsorption net will be discharged through the outlet, and the gas after discharge will be centrally treated.

[0006] As a preferred technical solution of the utility model, the anti-overgassing structure is a U-shaped air blocking tube, and the air blocking tube is connected to the drainage tube.

[0007] When the separated solution is less, the solution will stay in the choke tube part, thereby preventing the gas from overflowing from the drain port.

[0008] As a preferred technical solution of the utility model, the adsorption net is made of polymer resin material.

[0009] As a preferred technical solution of the utility model, it also includes an exhaust pipe connected to the gas outlet, and the exhaust pipe is coaxially arranged with the separation tank.

[0010] As a preferred technical solution of the utility model, the driving assembly includes a main shaft rotatably installed inside the separation tank and a first rotating shaft arranged perpendicular to the axis of the main shaft, the adsorption net is fixedly installed on the main shaft and a driving bevel gear is installed on the main shaft, and a driven bevel gear meshing with the driving bevel gear is installed on the first rotating shaft.

[0011] The meshing of the active bevel gear and the driven bevel gear drives the adsorption net to rotate rapidly, and the solution adsorbed on the adsorption net is thrown off by centrifugal force.

[0012] As a preferred technical solution of the utility model, it also includes an intake pipe connected to the air inlet, a second rotating shaft is rotatably installed inside the intake pipe, and a turbine is installed on one side of the second rotating shaft located inside the intake pipe, and the second rotating shaft extends out of the intake pipe and is connected to the first rotating shaft through a gear belt.

[0013] By arranging a turbine inside the intake pipe, the high-speed airflow will drive the turbine to rotate, thereby driving the second rotating shaft to rotate, and the first rotating shaft and the second rotating shaft connected by the belt will rotate synchronously.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] It can separate the cresol solution contained in the gas after the acidification reaction, and ensure the sealing of the device during the separation process to avoid the leakage of harmful gases, thereby improving the practical safety and environmental protection of the equipment.

The gas passing through the adsorption net 8 will be discharged through the gas outlet. The gas after discharge is centrally processed. The exhaust pipe 6 is coaxially arranged with the separation tank 1. The position of the exhaust pipe 6 is located at the center of the separation tank 1, which prevents the separated solution from easily entering the exhaust pipe 6. The separated solution will gather at the bottom of the separation tank 1 and be discharged through the liquid discharge port. The liquid discharge pipe 4 also includes a liquid discharge pipe 4 connected to the liquid discharge port, and the liquid discharge pipe 4 is provided with an anti-gassing structure. The anti-gassing structure is a U-shaped gas blocking pipe 5, and the gas blocking pipe 5 is connected to the liquid discharge pipe 4. By setting the U-shaped gas blocking pipe 5, when the separated solution is less, the solution will stay in the gas blocking pipe 5 part, thereby preventing the gas from overflowing from the liquid discharge port and ensuring the sealing of the device.

When in use, a driving motor can be installed on the separation tank 1, and the first rotating shaft 7 is driven to rotate by the driving motor, and the adsorption is driven under the meshing of the driving bevel gear 10 and the driven bevel gear 11. The rapid rotation of the attached net 8 not only increases the contact effect with the gas during the rotation of the adsorption net 8, but also can throw off the solution adsorbed on the adsorption net 8 through centrifugal force, further improving the separation effect while ensuring that the adsorption net 8 can continue to effectively adsorb. The second rotating shaft 3 is rotatably installed inside the intake pipe 2, and a turbine 12 is installed on one side of the second rotating shaft 3 located inside the intake pipe 2.
