Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device with a heat recovery function. Background Art

[0002] The waste gas treatment device with heat recovery function is an industrial equipment that can reduce energy consumption and environmental pollution. Its main purpose is to recover the heat from the high-temperature waste gas generated in the process, thereby improving energy efficiency, reducing the demand for raw materials and reducing waste gas emissions;

[0003] After searching, a Chinese patent discloses an exhaust gas treatment device with heat recovery function (authorization announcement number CN210613237U), which includes a body, a motor and a water pump. The end of the body is connected with an air inlet pipe, and a docking block is fixed at the top edge of the filter frame. The motor is fixed at the top edge of the body, and the output end of the motor is connected with a gear, and the gear shaft is connected to the inside of the body. A water outlet is reserved at the bottom of the body, and a water tank is fixed at the lower end of the body. A water pump is installed on one side of the water tank. A heat exchange chamber is fixed at one end of the body, and an air duct is installed in the heat exchange chamber. A water pipe is externally connected to the heat exchange chamber, and the water pipe is installed on the outside of the air duct. Although the above patent technology can perform multi-layer filtration and dust reduction treatment on the exhaust gas, it can also clean up impurities in real time to avoid blockage, recover the heat in the exhaust gas, and heat the water for subsequent use.

[0004] However, in the actual application of this patented technology, the above-mentioned device cannot convert the exhaust gas when in use. On the one hand, the direct discharge of exhaust gas containing pollutants into the environment without treatment will cause air pollution. For example, the emitted sulfides, nitrogen oxides, volatile organic compounds, particulate matter, etc. may have adverse effects on the environment and human health. On the other hand, harmful substances in the exhaust gas such as particulate matter, chemical gases, etc. can cause health problems such as respiratory diseases and cardiovascular diseases.

[0013] Through the above technical solution, the generation of waste can be reduced by using ceramic filters, which have less impact on the environment due to their durability and recyclability.

[0014] As a preferred embodiment, a filter box is fixedly connected to the top of the base and located on the side of the fixed frame away from the ceramic filter, a water supply pipe is fixedly connected to the top of the filter box, an activated carbon filter plate is fixedly connected to the upper part of the interior of the filter box, an air outlet pipe is fixedly connected to one side of the filter box, a second connecting pipe is fixedly connected to the side of the filter box away from the air outlet pipe, and one end of the second connecting pipe away from the filter box extends to the interior of the sleeve.

[0021] In the utility model, when the device is in use, the second gear drives the two first gears to mesh, so that the piston is driven to extract and convert the exhaust gas. On the one hand, by converting harmful components in the exhaust gas, such as converting NOx, SOx and volatile organic compounds into less harmful substances, the impact on air quality can be significantly reduced, and the risks of acid rain, photochemical smog and greenhouse effect can be reduced. On the other hand, the heat in the exhaust gas is recovered for heating, cooling or power generation, which can improve the energy efficiency of the entire factory, reduce dependence on external energy, reduce energy costs, and greatly improve the operation quality and utilization efficiency compared with traditional devices.
