Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment for refractory brick production furnaces, and specifically relates to a waste gas treatment device for refractory brick production furnaces. Background Technique

[0002] The waste gas from refractory brick production furnaces mainly contains pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter, fluorides, chlorides, and heavy metals (such as Pb, Cd), etc. These pollutants mainly come from the following aspects:

[0003] SO2: It mainly comes from the combustion of sulfur and sulfides in fuels and raw materials, as well as the reduction and decomposition of sulfates.

[0004] NOx: It mainly comes from thermal NOx, that is, nitrogen in the air reacts with oxygen at high temperature during fuel combustion to generate NOx.

[0005] Particulate matter: It mainly comes from green body dust, fuel entrainment, and working condition inhalation.

[0006] Fluorides and chlorides: They mainly come from the decomposition of fluorine-containing and chlorine-containing minerals in the green body and glaze during high-temperature firing.

[0007] Heavy metals: They mainly come from heavy metals such as Pb and Cd contained in the green body glaze.

[0008] These waste gases discharged into the atmosphere will cause great pollution to the atmosphere, and the existing waste gas treatment devices have a relatively large volume, which is not convenient for small processing plants to treat waste gas. Therefore, improvement is needed. Content of the Utility Model

The filter box passes through the insertion opening and is inserted into the insertion slot.

[0013] Preferably, the first filter screen and the second filter screen are perpendicularly distributed, with the first filter screen in a longitudinal distribution and the second filter screen in a transverse distribution.

[0014] Preferably, the strengthening treatment mechanism includes a heating frame, which is fixedly connected to the right side of the filter box in the processing shell. A heating sheet is fixedly connected inside the heating frame, and a heating elbow is fixedly connected in the middle of the heating sheet.

[0018] 1. For this waste gas treatment device for a refractory brick production furnace, through the provided purification mechanism, the processing shell is small in volume, which is convenient for waste gas treatment in small processing plants. At the same time, for the filtration and processing, with the first filter screen and the second filter screen designed horizontally and vertically, it can fully adsorb and purify harmful substances in the waste gas. Meanwhile, the volume of the filter screen can be controlled, ensuring that the volume of the entire device will not be too large, further facilitating waste gas treatment in small processing plants.

[0019] 2. For this waste gas treatment device for a refractory brick production furnace, through the provided strengthening treatment mechanism, the suction fan can quickly adsorb a large quantity of waste gas into the processing shell to ensure that the waste gas will not escape into the air due to slow processing speed. After being purified by the first filter screen and the second filter screen, at this time, the heat medium is connected to the heating elbow, and the heating elbow transfers heat to the heating sheet, ensuring that the waste gas can be heated at a high temperature after passing through the heating sheet, thereby destroying harmful substances in the waste gas and converting them into harmless or less toxic substances. Then, through the strong electromagnet, the substances in the waste gas are further adsorbed to ensure that a good purification effect can be achieved. At the same time, the volume of this structure is controllable, further ensuring that the volume of the treatment device is small to adapt to the use of small processing plants.

At the same time, the volume of the filter screen can be controlled to ensure that the volume of the whole device will not be too large, which further facilitates the waste gas treatment of small processing plants. On the premise of realizing environmental protection, the cost can also be saved.

[0040] The suction fan 35 can quickly adsorb a large number of waste gases into the treatment shell 1 to ensure that the waste gases will not escape into the air due to slow treatment speed. When purified by the first filter screen 24 and the second filter screen 25, at this time, the heat medium is connected to the heating elbow 32, and the heating elbow 32 transfers heat to the heating sheet 33, which can ensure that the waste gases can be heated at a high temperature after passing through the heating sheet 33, so as to destroy the harmful substances in the waste gases and thus be converted into harmless or less toxic substances.
