[0001] The utility model relates to the technical field of filtering devices, in particular to a waste gas water treatment device. Background Art

[0002] Components are needed in the polyester production process. The main function of the components is to filter and pressurize the melt as it passes through. As an accessory that filters the melt, the components need to be replaced regularly. Most of the replaced components can still be recycled, but they need to be calcined to burn the solidified melt inside into ash for disassembly and cleaning. Calcination will produce waste gas. These waste gases with impurities such as dust and dirt are directly discharged without treatment, which will pollute the environment. Therefore, a device that can filter dust and dirt in the waste gas is needed. Summary of the invention

[0006] Preferably, the water-gas mixer includes a water-gas mixing tank, a water inlet pipe arranged on the top of the water-gas mixing tank, and an air inlet pipe arranged on one side of the water-gas mixing tank.

[0016] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0017] like Figure 1As shown, a waste gas water treatment device comprises a calcining furnace 1, an exhaust pipe 2 arranged on the furnace cover of the calcining furnace 1, the outer end of the exhaust pipe 2 is connected to a water-gas mixer 3 through a pipeline, and the discharge end of the water-gas mixer 3 is provided with a water-gas separation tank 7. The waste gas discharged through the exhaust pipe 2 during calcination in the calcining furnace 1 enters the water-gas mixer 3 and is fully mixed with water to achieve adsorption of solid matter in the waste gas, and the mixed liquid after mixing enters the water-gas separation tank 7 again to separate gas and sewage and is discharged to the outside.

[0018] During the calcination of the replaced components in the calcining furnace 1, the exhaust gas discharged through the exhaust pipe 2 enters the water-gas mixer 3 through the pipeline, and the gas and water are mixed by the water-gas mixer 3 before flowing to the water-gas separation tank 7, so that the dust and other substances in the gas entering the water-gas mixer 3 can be adsorbed by water, and then enter the water-gas separation tank 7, the gas will not be directly discharged with dust and other impurities when it is discharged, so as not to pollute the environment, and the characteristic of water being able to adsorb dust and dust is used, and the waste gas is treated with water as a carrier, and the dust and other impurities in the waste gas are adsorbed, so that the waste gas is purified to a greater extent. The structure is relatively simple, easy to operate, has a more targeted matching degree with the existing component calcining equipment, and the effect of purifying waste gas is also more obvious.

[0019] A further improvement is that the water-gas mixer 3 includes a water-gas mixing tank 9, a water inlet pipe 5 arranged on the top of the water-gas mixing tank 9, and an air inlet pipe 4 arranged on one side of the water-gas mixing tank 9. The exhaust pipe 2 is connected to the air inlet pipe 4 through a pipeline. After the exhaust gas enters the water-gas mixing tank 9, it contacts and mixes with water.

[0020] When the exhaust gas is mixed with water through the water-gas mixer 3, the gas enters from the side air inlet pipe 4, and the water enters from the top water inlet pipe 5, and the water outlet 10 is located at the bottom of the water-gas mixing tank 9. When water and gas enter and are discharged outward, the dust, dirt and other impurities entrained in the gas will contact and be adsorbed before the water, and then be discharged outward. The filtering method is simpler, the structure of the water-gas mixing tank 9 is simpler, and the impact force of the water is greater, which can make some impurities in the cavity of the water-gas mixing tank 9 quickly mix with the water.

[0021] As a further improvement, a nozzle 6 is provided at the water outlet end of the water inlet pipe 5 , and the water flowing out of the water inlet pipe 5 is discharged into the water-gas mixing tank 9 in a dispersed structure through the nozzle 6 .

[0022] Since the exhaust gas is not directly injected into the water when it enters, some impurities will float upwards. Therefore, after the water inlet pipe 5 is located at the top and the nozzle 6 is installed, the outflowing water can be scattered, so that the floating impurities can be mixed with the water more quickly and effectively.

[0023] As a further improvement, a vacuum pump 11 is provided between the water-gas separation tank 7 and the water-gas mixing tank 9. The water and exhaust gas in the water-gas mixing tank 9 are fully mixed by the power of the vacuum pump 11 to achieve adsorption of solid matter in the exhaust gas. The mixed liquid is transported to the water-gas separation tank 7 by the vacuum pump 11 to separate the gas and sewage and discharge them to the outside.

[0024] When the water and exhaust gas in the water-gas mixing tank 9 are mixed, the adsorption power of the vacuum pump 11 can form a vortex structure inside it, adsorbing the solid matter in the exhaust gas, thereby achieving more complete mixing. At the same time, the water-gas mixing can be achieved and quickly transported between devices through pipelines, avoiding the problem of impurities clogging the pipeline.

[0025] Further improvement is that the top of the water-gas separation tank 7 is provided with an exhaust port 8, and the side of the water-gas separation tank 7 is provided with a water outlet 10, and the water outlet 10 is connected to the sewage treatment tank. The upper opening of the separation tank is used as the exhaust gas outlet, and the lower opening is used as the wastewater outlet. The water-gas separation tank 7 can utilize the characteristics of gas going up and water flowing down, and the solid impurities in the treated exhaust gas are filtered out, and the exhaust gas is purified. In addition, the generated wastewater can be collected to the sewage treatment station for treatment, so as to achieve the separation of water and gas, and the structure is simpler.

[0026] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
