[0002] High-temperature roasting is a key process in the preparation of many petroleum refining and chemical catalysts and special materials. Vertical roasting furnaces are widely used in the roasting process due to their simple structure and easy maintenance. Traditional vertical roasting furnaces produce a large amount of reflux waste liquid after condensation of exhaust gas due to the low temperature of the exhaust pipe during the start-up and shutdown of the roasting process, causing semi-finished product pollution and affecting product quality. In order to facilitate the treatment of the exhaust gas generated by the vertical roasting furnace, a vertical roasting furnace equipped with an exhaust gas treatment structure is required.

[0003] The existing vertical roasting furnace equipped with an exhaust gas treatment structure generally includes a furnace body, an exhaust gas outlet, an exhaust gas tank, an activated carbon placement layer fixedly connected to the inside of the exhaust gas tank by bolts, a tank cover fixedly connected to the exhaust gas tank by multiple bolts, and an exhaust gas outlet. When working, the exhaust gas enters the exhaust gas tank, and toxic and harmful gases and dust impurities are adsorbed and filtered by the activated carbon.

[0004] The disadvantage of the existing vertical roasting furnace equipped with an exhaust gas treatment structure is that since the tank cover and the exhaust tank are fixedly connected by multiple bolts, it is troublesome to disassemble and assemble the tank cover when replacing the activated carbon. Therefore, it is necessary to propose a vertical roasting furnace equipped with an exhaust gas treatment structure to solve the above-mentioned problem. Utility Model Content

[0034] Working principle: When working, the exhaust gas inside the furnace body 1 will enter the inside of the spray box 2 along the bend pipe 19, and at the same time the water pump 3 will pump water into the water collecting box 4, and spray it into the inside of the spray box 2 along multiple spray heads 5, thereby absorbing the exhaust gas that can be dissolved in water, and the gas that cannot be dissolved in water will enter the inside of the treatment box 6. At the same time, activated carbon can be placed through the placement of the mesh box 7, so that the gas enters the placement mesh box 7 and contacts with the activated carbon, and then is adsorbed by the activated carbon. After sufficient adsorption, the air outlet valve pipe 26 is opened to discharge the purified air. When the placement mesh box 7 is to be fixed, the push plate 9 is pushed to the right, and then the push plate 9 and the fixing ring 12 are moved to the right respectively, so that the first sealing ring 10 and the left side of the treatment box 6 are squeezed, and the second sealing ring 1 3 is squeezed against the right side of the inner wall of the treatment box 6, thereby preventing the exhaust gas from overflowing the treatment box 6, until they are squeezed tightly respectively.
