Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a waste gas purification device. Background Art

[0002] Waste gas purification treatment mainly treats the waste gas generated in the industrial production process to meet the prescribed emission standards, thereby reducing the emission of atmospheric pollutants and reducing pollution and damage to the environment. Waste gas purification treatment methods include but are not limited to absorption purification, filtration, adsorption, catalytic conversion, biodegradation, etc. Through waste gas purification treatment, the emission of atmospheric pollutants can be effectively reduced, the pollution and damage to the environment can be reduced, and the ecological environment and human health can be protected. At the same time, waste gas purification treatment can also improve production efficiency and reduce the environmental protection costs of enterprises, bringing greater economic benefits to enterprises. It is suitable for various industrial production fields, such as chemical, pharmaceutical, printing, coating, rubber, plastic, etc.

[0003] At present, in industries that require a large amount of drying equipment, such as food, chemical, pharmaceutical, electronic, spraying, printing, papermaking, chemical fiber, etc., in these industries, drying equipment usually needs to raise the air to a certain temperature to process the materials, and the treated exhaust gas is usually at a high temperature. Directly discharging it into the atmosphere will cause a lot of energy waste. By adding heat recovery equipment such as heat exchange boxes to the exhaust gas emission system, it is possible to recover and reuse waste heat, improve energy utilization efficiency, and reduce carbon emissions. However, in existing exhaust gas purification devices, the exhaust gas waste heat recovery structure generally uses a water tank penetrated by an exhaust gas pipe. Although it has waste heat recovery efficiency, the exhaust gas passes through the water tank for a short time, and the waste heat recovery efficiency is low. In addition, the equipment as a whole is relatively bulky and not easy to move. For this reason, the present application proposes an exhaust gas purification device. Utility Model Content

Among them, since the coil 12 is provided in the waste heat recovery tank 2 for exhaust gas drainage, water is pre-injected into the waste heat recovery tank 2. During the exhaust gas purification and drainage process, the exhaust gas exchanges heat with the water in the waste heat recovery tank 2 when passing through the coil 12, so as to realize the recovery of the waste heat of the exhaust gas, and the mixer 7 can be used to make the water in the waste heat recovery tank 2 flow, thereby improving the heat exchange efficiency between water and exhaust gas and improving the waste heat recovery effect.

[0027] As a preferred technical solution in this embodiment, the mixer 7 includes a stirring paddle 16 rotatably installed in the waste heat recovery tank 2 and a motor 15 installed at the top of the waste heat recovery tank 2 for driving the stirring paddle 16 to rotate. Starting the motor 15 to drive the stirring paddle 16 to rotate can make the water in the waste heat recovery tank 2 flow, thereby improving the heat exchange efficiency between water and waste gas.
