Description

Technical Field

[0001] This utility model belongs to the field of low-quinoline coal tar pitch production technology, and in particular relates to a gas purification device for low-quinoline coal tar pitch production. Background Technology

[0002] Low-quinoline coal tar pitch refers to coal tar pitch with a low content of quinoline insolubles. Waste gas is generated during the production of low-quinoline coal tar pitch. In order to reduce the adverse environmental impact of the waste gas in the production of low-quinoline coal tar pitch, it is necessary to operate a waste gas purification device to purify the waste gas in the production of low-quinoline coal tar pitch.

[0003] A search revealed a quinoline production waste gas purification device disclosed in patent publication number CN216825592U. The device includes a purification chamber, an inlet pipe mounted on top of the chamber, a filter plate installed inside the reaction chamber, a fixing block mounted outside the groove, a sliding groove on the inner side of the filter plate, a retaining plate penetrating the inner side of the fixing cylinder, a condenser pipe installed below the filter plate, a liquid outlet pipe installed below the filter plate, a baffle plate installed on one side of the reaction chamber, an adsorption plate installed inside the filter chamber, a deodorizing plate installed on top of the filter screen, and an exhaust pipe installed on one side of the purification chamber. This device avoids the inconvenience of cleaning the filter plate, increases the device's efficiency and lifespan, provides convenience for users, and improves the device's working efficiency and purification efficiency.

[0004] The aforementioned waste gas purification device for quinoline production includes an inlet pipe installed above the purification chamber, with a reaction chamber below the inlet pipe. A filter plate is installed inside the reaction chamber, a condenser pipe is installed below the filter plate, a permeable plate is installed below the condenser pipe, and a liquid outlet pipe is installed below the permeable plate. A baffle is installed on one side of the reaction chamber, and a filter chamber is installed on the other side of the baffle. An adsorption plate is installed inside the filter chamber, and a filter screen is installed above the adsorption plate. A deodorizing plate is installed on top of the filter screen. An exhaust pipe is installed on one side of the purification chamber. A clamping receiving plate is used to slide a retaining plate inside a fixed cylinder, causing the retaining plate to compress the air bladder below, thus engaging and disengaging the retaining plate from the retaining groove. The filter plate is then removed from the groove for cleaning. When waste gas passes through the inlet pipe… Upon entering the reaction chamber, the exhaust gas undergoes initial filtration through a filter plate. It then reacts with the condenser tube, causing harmful substances in the exhaust gas to liquefy and flow through a permeable plate into an outlet pipe for discharge. Next, a valve inside the baffle is activated, allowing the exhaust gas to enter the filtration chamber. There, it is adsorbed and filtered by the activated carbon on the adsorption plate inside the filtration chamber. Finally, it is filtered and deodorized by a filter screen and a deodorizing plate before being discharged through an exhaust pipe. However, it is inconvenient to simultaneously disassemble and install the filter screen, adsorption plate, filter plate, and deodorizing plate, increasing the number of steps required for cleaning these components and the workload. Furthermore, it is difficult to clean blockages on the filter screen, adsorption plate, filter plate, and deodorizing plate, thus reducing the exhaust gas flow effect and purification efficiency.

[0005] To address these issues, we provide a gas purification device for the production of low-quinoline coal tar pitch. Utility Model Content
