Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology for dry film drying, specifically a device for classifying and treating the components of waste gas during the dry film drying process. Background Technology

[0002] Dry film drying is a key process in the manufacturing or application of dry film. It mainly removes moisture or solvents from the dry film by heating, so that it forms a stable solid film. The heat for drying the dry film is provided by a regenerative thermal incinerator, which is an environmentally friendly device that recovers heat through a heat storage medium to achieve efficient waste gas treatment.

[0003] Because the exhaust gas entering the RTO contains a large number of large particles, these particles will adhere to the heat storage ceramic. Long-term accumulation will cause the heat storage effect of the heat storage ceramic to deteriorate, affecting the operation of the RTO. Moreover, after accumulating to a certain extent, the heat storage ceramic will become completely unusable and need to be replaced, which is costly. Therefore, it does not meet the current needs. To address this, we propose a waste gas composition classification and treatment device for the dry film drying process. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas composition classification and treatment device for the dry film drying process, in order to solve the problems mentioned in the background art, such as the presence of a large number of large particles in the waste gas entering the RTO, which will adhere to the heat storage ceramic, and the long-term accumulation will cause the heat storage effect of the heat storage ceramic to deteriorate, affecting the operation of the RTO, and the heat storage ceramic will become completely unusable after accumulating to a certain extent, requiring replacement, which is costly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas composition classification and treatment device for dry film drying process, comprising a waste gas purification box, an inlet pipe fixed at the top of the waste gas purification box, a waste gas conveying pipe inserted and fixed inside the inlet pipe, an outlet pipe fixed on one side of the waste gas purification box, a waste gas discharge pipe inserted and fixed inside the outlet pipe, a separation plate fixed inside the waste gas purification box, and an interception plate fixed on the surface of the separation plate.

[0006] Preferably, a filter block is inserted and connected to the rear of the exhaust gas purification box, and a one-way solenoid valve is provided inside the end of the filter block that connects to the exhaust gas purification box.

[0007] Preferably, the separating plate is inclined at an angle of 30 to 60 degrees, and the middle of the intercepting plate arches upwards towards the higher end of the separating plate.

[0008] Preferably, the separation plate has notches on both sides, and the inside of the notches is filled with filter blocks, the diameter of the filter holes of the filter blocks being larger than the diameter of the particles in the exhaust gas.

[0009] Preferably, the interceptor plate includes a connecting housing, the top of which is bent in an L-shape, and a filter plate is provided between the connecting housing and the separation plate.

[0010] Preferably, the surface of the separation plate is provided with a plurality of ventilation grooves, and the distance between the end of the ventilation groove and the side of the separation plate is equal to the thickness of the connecting shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention adds a separation plate to the buffer tank, which adsorbs large particulate waste gas onto the plate and accumulates before flowing into the bottom of the buffer tank. The remaining part enters the RTO for combustion and is cleaned regularly. This prevents the waste gas from entering the heat storage ceramic and causing ceramic contamination, thereby improving the service life of the ceramic and reducing equipment operating costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1 to 3 As shown, a waste gas composition classification and treatment device for dry film drying process includes a waste gas purification box 1. An inlet pipe 2 is fixed to the top of the waste gas purification box 1. A waste gas conveying pipe 3 is inserted and fixed inside the inlet pipe 2. An outlet pipe 4 is fixed to one side of the waste gas purification box 1. A waste gas discharge pipe 5 is inserted and fixed inside the outlet pipe 4. A separation plate 6 is fixed inside the waste gas purification box 1. An interception plate 7 is fixed to the surface of the separation plate 6. Multiple interception plates 7 fixed to the surface of the interception plate 7 are used to intercept and filter large particles in the waste gas, so that the filtered waste gas enters the heat storage ceramic through the waste gas discharge pipe 5, thereby improving the service life of the heat storage ceramic.

[0019] The interceptor plate 7 includes a connecting housing 71, the top of which is bent in an L-shape. A filter plate 72 is provided between the connecting housing 71 and the separation plate 6. The surface of the separation plate 6 is provided with multiple air permeable grooves 9. The distance between the end of the air permeable groove 9 and the side of the separation plate 6 is equal to the thickness of the connecting housing 71. The filter plate 72 intercepts particulate matter in the exhaust gas, while the air permeable grooves 9 ensure that the gas can pass through the separation plate 6.

[0020] The separation plate 6 is inclined at an angle of 30 to 60 degrees. The middle of the interception plate 7 is arched towards the higher end of the separation plate 6. The arched interception plate 7 guides the intercepted large particles to slide down to both ends of the interception plate 7, and then through the filler filter block 8 to fall to the bottom of the exhaust gas purification box 1 and be collected.

[0021] Both sides of the separation plate 6 are provided with notches, and the inside of the notches is filled with filter blocks 8. The diameter of the filter holes of the filter blocks 8 is larger than the diameter of the particles in the exhaust gas, so that the particles intercepted by the interception plate 7 can fall smoothly to the bottom of the exhaust gas purification box 1 and be collected after sliding to both ends of the interception plate 7.

[0022] A filter block 8 is inserted and connected to the rear of the exhaust gas purification box 1. The end of the filter block 8 connected to the exhaust gas purification box 1 is equipped with a one-way solenoid valve. The filter block 8 is used to collect the waste liquid collected at the bottom of the exhaust gas purification box 1, so as to realize the periodic cleaning of the inside of the exhaust gas purification box 1.

[0023] Working Principle: During the purification of waste gas generated during the dry film drying process, the waste gas to be purified is first transported into the waste gas purification box 1 through the waste gas conveying pipe 3. After entering the waste gas purification box 1, the waste gas flows towards the waste gas discharge pipe 5 due to gas flow. At this time, the waste gas will pass through the separation plate 6 and the interception plate 7. When the waste gas passes through the separation plate 6 and the interception plate 7, it first comes into contact with the filter plate 72. When the waste gas passes through the filter plate 72, the filter plate 72 intercepts the large particles in the waste gas. The intercepted particles slide down the surface of the filter plate 72 to both ends of the filter plate 72. After the particles reach the end of the filter plate 72, they pass through the filler filter block 8 and fall into the bottom of the waste gas purification box 1. The gas passing through the filter plate 72 enters below the separation plate 6 through the air permeable groove 9. Finally, the purified gas is collected along the waste gas discharge pipe 5. The large particles in the waste gas are adsorbed on the separation plate to prevent them from entering the heat storage ceramic and causing ceramic pollution, thereby improving the service life of the ceramic and reducing the operating cost of the equipment.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
