Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a large-scale waste gas treatment device for glue coating preparation and treatment. Background Art

[0002] The specific composition of the waste gas generated during the glue coating preparation process will be affected by many factors such as the type of glue used, solvent, production process, etc. The waste gas generated during the glue coating preparation process usually needs to pass through an effective treatment device to ensure that the waste gas emissions comply with environmental regulations and protect the environment and workers' health;

[0003] The solvents and volatile organic compounds in the glue coating process can evaporate and become waste gas. These compounds may include toluene, xylene, ethanol, ether compounds, etc., which may have adverse effects on air quality and human health. In addition, tiny particles may be generated during the gluing process. These particles contain glue components, particles generated by solvent evaporation, etc. These waste gases and particles form a large range of waste gases inside the workshop, which may have adverse effects on air quality and human health.

[0039] See also Figure 1 and 2 In this embodiment, a large-scale waste gas treatment device for glue coating preparation is used to spray, adsorb and filter the waste gas generated by glue coating preparation in sequence, so as to effectively remove harmful gases and particulate matter in the waste gas.

[0040] Specifically, it includes a spray tower 1, an adsorption box 2, a filter box 3 and a fan 4; the spray tower 1 is connected with an air inlet pipe 5 for conveying the exhaust gas to the inside of the spray tower 1 for spraying treatment of the exhaust gas.

[0041] In actual use, the waste gas generated by the glue coating preparation is transported to the interior of the spray tower 1 through the air inlet pipe 5. The waste gas is sprayed by water in the spray tower 1. The liquid can be evenly sprayed into the waste gas through the spray system, so that the droplets are fully in contact with the pollutants in the waste gas, which is helpful to degrade and absorb harmful substances in the waste gas.

[0042] Furthermore, in order to adsorb harmful gases in the exhaust gas, the adsorption box 2 is connected to the spray tower 1 through the first connecting pipe 6, so as to transport the sprayed exhaust gas to the interior of the adsorption box 2 for adsorption treatment of the exhaust gas.

[0043] In actual settings, the waste gas after spraying is transported to the interior of the adsorption box 2 through the first connecting pipe 6, and the harmful gases in the waste gas are effectively adsorbed through the adsorption system inside the adsorption box 2.

[0044] Furthermore, in order to filter particulate matter in the exhaust gas, the filter box 3 is connected to the adsorption box 2 through the second connecting pipe 7, so as to transport the adsorbed exhaust gas to the interior of the filter box 3 for filtering the exhaust gas.

[0045] In actual settings, the extracted exhaust gas is transported to the interior of the filter box 3 through the second connecting pipe 7, and the exhaust gas is filtered through the filtering system inside the filter box 3, thereby effectively intercepting particulate matter in the exhaust gas.

[0046] In addition, in order to provide suction for the entire treatment device, the fan 4 in this embodiment is installed on a side close to the adsorption box 2, and the input end of the fan 4 is connected to the filter box 3, that is, when the fan 4 is running, the air in the filter box 3, the adsorption box 2 and the spray tower 1 is extracted in turn.

[0047] See also Figure 3 In order to effectively spray the exhaust gas, a water spray ring 101 is horizontally arranged inside the spray tower 1 in this embodiment, and a water pump 102 whose output end is connected to the water spray ring 101 is installed on the spray tower 1; a water inlet pipe 103 is connected to the input end of the water pump 102, and the end of the water inlet pipe 103 away from the water pump 102 is connected to a water storage tank in the outside world.

[0048] During actual use, the control switch of the water pump 102 is turned on, and the water inside the water tank is extracted through the water inlet pipe 103 inside the input end of the water pump 102, and transported to the inside of the water spray ring 101 through the output end of the water pump 102, and sprayed out through the water spray ring 101 to spray the exhaust gas inside the spray tower 1, thereby effectively degrading and absorbing harmful substances in the exhaust gas.

[0049] Furthermore, in order to ensure that the water body can fully contact the exhaust gas, a plurality of nozzles are connected in a circular array on the inner side of the water spray ring 101 to divide the sprayed water into a plurality of water columns, which can effectively degrade and absorb harmful substances in the exhaust gas through contact with the exhaust gas.

[0050] In actual settings, in order to ensure that the exhaust gas can pass through the inner side of the water spray ring 101, the center point of the water spray ring 101 and the center point of the spray tower 1 are located on the same plumb line, and the water spray ring 101 is located above the output end of the air inlet pipe 5, that is, when the exhaust gas passes through the inner side of the water spray ring 101, the sprayed water can effectively contact the exhaust gas.

[0051] In addition, in order to facilitate the discharge of wastewater in the spray tower 1, a sewage pipe is connected to the outer peripheral surface of the spray tower 1 and located below the air inlet pipe 5. By opening the sewage pipe, the wastewater mixed with the exhaust gas at the bottom of the spray tower 1 can be discharged.

[0054] Furthermore, in order to increase the contact efficiency between the exhaust gas and the adsorption plate 201, a certain gap is retained between two adjacent adsorption plates 201 in the present embodiment. In addition, a certain gap is retained between the upper and lower adsorption plates 201 and the bottom and top of the inner wall of the adsorption box 2, respectively, so that the exhaust gas contacts at least two adsorption plates 201 from left to right in turn, thereby effectively increasing the contact time and area between the exhaust gas and the adsorption plate 201, and effectively absorbing the harmful gases in the exhaust gas.

[0057] In addition, in order to facilitate the cleaning of the filter 303 without stopping the machine, the filter 303 originally located inside the filter box 3 is moved to the outside of the filter box 3 by pushing the frame 302, and the filter 303 located outside the filter box 3 is moved to the inside of the filter box 3. At this time, the filter 303 that needs to be cleaned is moved out from the inside of the frame 302 for cleaning.

Corresponding to the bolts 305, threaded holes are opened on the front and rear sides of the filter box 3.

[0059] In actual use, the baffle 304 on the side of the filter 303 moved close to the inside of the filter box 3 is fitted with the outer side of the filter box 3, and then the bolt 305 on the baffle 304 is rotated so that the bolt 305 extends to the inside of the threaded hole, thereby fixing the baffle 304 to ensure the stability of the filter 303 when intercepting particulate matter in the exhaust gas.
