Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an exhaust gas treating apparatus, and more particularly to an apparatus for treating droplets/particulate exhaust gas. More specifically, the present invention relates to an exhaust gas treatment apparatus for treating droplets/particulates and gaseous contaminants. [Prior Art] _ Nowadays, the concentration of high-tech industries is increasing and the number of air pollution problems is very special. The concentration of exhaust gas emitted by some processes is low, but the total amount of emissions is very high. The EPD has therefore announced the "Air Pollution Control and Emissions Standards for Semiconductor Manufacturing Industry" as the relevant air pollution prevention system. • In the current semiconductor component and optoelectronic component manufacturing process, there are usually various exhaust gases generated. The emissions of organic exhaust gases, inorganic acid gases, and ammonia are large. The clean room air quality that the photovoltaic industry and the semiconductor industry pay attention to is greatly affected by inorganic acid gas and ammonia gas. Φ One of the most widely used exhaust gas treatment technologies in the industry is wet scrubbing technology. This washing technique absorbs gaseous contaminants into the washing liquid by means of a mass transfer mechanism between the gas and the liquid, and periodically replaces, washes or controls the pH value to obtain stable exhaust gas removal efficiency. The so-called mass transfer mechanism mainly uses the difference in concentration of contaminants between gas and liquid to cause the contaminants to diffuse from the gas and transport it to the washing liquid. The scrubber is a 1299280 treatment unit that treats both gaseous and particulate contaminants. The mechanism for handling gaseous pollutants in this device is the mass transfer mechanism described above, and the mechanism for treating particulate/droplet contaminants is described in the figure, and there are roughly five interactions between the filter unit 100 and the particulate/droplet contaminants. · Gravity sedimentation 110, inertial collision 120, electrostatic attraction 130, direct interception 14〇 and diffusion 150, the main functions of which are gravity settlement 11〇 and inertial collision 120, due to the larger particle size/droplet pollutants The two main effects are affected, and then intercepted by the filter unit 1〇〇, to achieve the purpose of filtering particles/droplet contaminants; but for particle/droplet contaminants with small particle size (such as less than 1 micron), it is mainly necessary Depending on the effect of electrostatic attraction n〇, it can be effectively adsorbed by the filter unit 100. Currently, the electrostatic adsorption capacity of the conventional device is poor or the operation cost is high. A known technique for effectively removing particulate/droplet contaminants is a transitional technique. This technology usually includes a front filter section and a demister, wherein the front filter section often uses a fiber filter, a non-woven filter or a woven filter as a filter or medium for collecting particulate/droplet contaminants; a conventional one The mist eliminator is a continuous s-shaped tubular structure that intercepts particulate/droplet contaminants therethrough by its continuous curved wall structure. The filtration efficiency of the pre-filter section depends mainly on the flow rate of the gas. The filtration efficiency is usually higher when the flow rate is faster, but the degree of wear due to the gas pressure is also relatively increased (for example, the pressure applied to the fiber filter is about 6). To 8 吋 water column height, the pressure applied to the non-woven filter screen is about 20 忖 water column two), when the gas flow rate is low, although the filter life can be extended, but one filter efficiency will decrease, two The particulate/droplet contaminants in the exhaust gas may then rise from the screen. This filtration technology is very effective in treating particulate/droplet contaminants, but the high pressure loss of 7 1299280 produced by the filter cannot reduce the energy and consumables cost of this filtration technology, and it is not suitable for connection. The rear end of the system of air volume exhaust. The problems of the above conventional methods include that the washing equipment designed to treat gaseous pollutants cannot effectively remove the particulate/droplet contaminants in the exhaust gas; and the filtering technology consumes a lot of energy, the cost of consumables is high, and the particle size cannot be effectively filtered. Consideration of particle/droplet contaminants less than 1 micron. Therefore, there is a need for a more efficient, lower cost technology to comply with environmental regulations, and the above problems can be overcome by the present invention. SUMMARY OF THE INVENTION To solve the above and other problems and to attain the technical advantages of the present invention, the present invention provides an exhaust gas treatment apparatus incorporating a washing apparatus and a filtering apparatus to improve the performance of the existing exhaust gas treating apparatus. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an exhaust gas treatment apparatus having a filtering device and a gas pumping device for treating exhaust gas containing droplets/particulate contaminants. Another object of the present invention is to provide an exhaust gas treating apparatus having a washing apparatus, a filtering apparatus and a gas pumping apparatus for treating exhaust gas mixed with liquid droplets/particulates and gaseous pollutants. According to the above object of the present invention, an exhaust gas treating apparatus which can effectively treat exhaust gas containing droplets/particulate pollutants is proposed. In accordance with a preferred embodiment of the present invention, the exhaust gas treatment apparatus includes a filtration device and a gas pumping device, the filtration device mainly comprising a humidification fluid supply device, a filter screen, and a droplet collection tank. The humidifying liquid supply device is connected with the humidifying liquid for the 1299280 and the nozzle is connected to the end of the humidifying liquid supply pipe. A part of the humidifying liquid supply pipe and the nozzle are located before the filter, the liquid collecting groove Located below the filter screen, the gas pumping device is connected to a certain distance behind the filter screen to avoid damage caused by long-term exposure to trace amounts of acid and alkaline gases. In accordance with the purpose of the present invention, an exhaust gas treatment apparatus is proposed which is effective for treating exhaust gas mixed with droplets/particulates and gaseous pollutants. According to a preferred embodiment of the present invention, the exhaust gas treatment device comprises a washing device, a filtering device and a gas pumping device, and the washing device can process the exhaust gas mixed with gaseous pollutants such as acid and gas; the filtering device includes Wet supply unit, filter and droplet collection tank. A humidification liquid supply pipe is connected by the humidification liquid supply device, and a nozzle is connected to the end of the humidification liquid supply pipe, and the arrangement of the humidification liquid supply pipe and the nozzle can uniformly provide the humidification liquid to completely wet the concrete net. The humidifying liquid can reduce the surface energy of the filter, wherein the treated pollutants can include droplet/particle contaminants having a particle diameter smaller than 丨 micrometer; the droplet collecting tank is located below the filter screen, and the collecting filter is collected. The droplets of the pollutants are adsorbed and discharged from the droplet discharge port; the gas pumping device is connected at a certain distance behind the filter screen to avoid damage due to long-term exposure to a trace amount of acid or alkali. The washing apparatus of the preferred embodiment of the present invention may also be connected after the transition device. It can be seen from the above preferred embodiments of the present invention that the application of the present invention has the following advantages: 1) It is not necessary to use a high-precision filter having a small aperture and a high pressure loss in order to filter minute droplets/particulate contaminants. This reduces the cost of consumables. 2. The humidification liquid supplied to the filter net can reduce the surface energy of the filter by using the interface activity of 1299280, which does not need to continuously consume energy and increase the electrostatic attraction of the filter. . 3 · Due to the use of a larger pore size and a lower pressure loss filter, the efficiency of treating droplets/particulate pollutants with a particle size of less than 1 μm is better than conventional filtration techniques, so it can be connected to the generation of high-volume exhaust gas. The rear end of the equipment does not need to cooperate with high horsepower and high energy consumption pumping system.

The particulate contaminants are adsorbed onto the humidified filter unit 210. When the droplet/particle contaminant content adsorbed by the filtering device 210 reaches a certain level, the droplet 211 that has flowed down is collected by the droplet collecting tank 230 and discharged from the droplet discharging port 23 1 to the outside of the exhaust gas treating device 200. . The gas passing through the filtering device 210, which is air 250 free of droplets/particulate contaminants, is also discharged by the gas pumping device 240 to the outside of the exhaust gas treating device 200. Referring to FIG. 3, an exhaust gas treatment device 400 including a body 410, a mist eliminator 420, a humidification device 430, a filtration device 440, and a gas pumping device 450 is illustrated in accordance with a preferred embodiment of the present invention. The gas inlet end 411 of the crucible body 410 is connected to the exhaust gas source, and the gas outlet end 412 is connected to the gas pumping device 450. The gas inlet end 411 is connected to the gas outlet end 412 by a joining section 413. The mist eliminator 420 is disposed at the gas inlet end 411 of the exhaust gas treatment device 400 and is disposed at an inclined position. The humidifying device 430 is disposed in the connecting section 413, and has one or more humidifying liquid supply pipes 421, and each of the humidifying liquid supply pipes 421 is provided with a nozzle 422. The humidification liquid supply pipe 421 may supply a humidification liquid 423, which may include water, an aqueous solution, an aqueous surfactant solution, an aqueous ionic surfactant solution, or any combination of the above. The filter device 440 has a filter material having a low pressure loss; the filter material composition 11 1299280 may be a fiber filter, a non-woven filter screen, and a woven filter mesh. The humidifying liquid 423 is sprayed on the filter material of the filtering device 440 by the nozzle 422 described above, so that the filter material composition is completely wetted to continuously maintain the adsorption force with high static electricity. The gas pumping device 450 is connected to the gas outlet end 412 after the filter device 440 to pump the filtered and treated gas.

At this time, since the humidifying liquid 423 is composed of the filter material sprayed on the filtering device 440, the filter material composition is fully wetted to continuously maintain the adsorption force with high static electricity, and the filtering device 440 can make the exhaust gas very minute (for example, 1 micrometer). The particles and droplets are effectively adsorbed and filtered. The exhaust gas treated by the filtering device 440 is discharged by the gas pumping device 450 to the clean air 460 which is free of droplets/particulate contaminants. Conventional filter devices often use filters with smaller mesh apertures. The smaller the aperture, the better the filtration effect, but the greater the pressure loss generated by the filter, the energy and consumables necessary to maintain the operation of the equipment. The cost will increase. However, the humidification liquid in the filtration device of the present invention contains water, an aqueous solution, an aqueous solution of an surfactant, an aqueous solution of an ionic surfactant, or any combination of the above, and the filter medium having a lower pressure loss is wetted by the humidification liquid. Because it changes its surface energy and can maintain the high electrostatic adsorption force, the entire exhaust gas treatment equipment can achieve good filtration effect with less energy, so it can effectively save energy and consumables cost 12 1299280. Referring to Figure 4, an exhaust gas treatment device 500 in accordance with a preferred embodiment of the present invention is illustrated. The exhaust gas treatment device 500 includes a washing device 510, a filtering device 520, and a gas pumping device 530. The filter device 520 is composed of a filter material having a low pressure loss; the filter material may be a fiber filter, a mesh, a non-woven filter, and a woven filter. And using a humidifying liquid containing water, an aqueous solution, an aqueous surfactant solution, an aqueous ionic surfactant solution or any combination of the above four to be sprayed on the filter material composition of the filtering device, so that the filter material is fully wetted to continuously maintain High static adsorption. In practice, the washing device 510 is responsible for treating gaseous pollutants such as acid and alkaline gas in the exhaust gas, and the filtering device 520 is connected to the washing device 510 and effectively treating droplets/particulate pollutants in the exhaust gas (including a particle diameter of less than 1). The micron droplets/particles, the gas pumping device 530 discharges the air treated by the filtering device 520 out of the exhaust gas treatment device. Referring to Figure 5, an exhaust gas treatment device 500 in accordance with a preferred embodiment of the present invention is illustrated. The exhaust gas treatment device 500 differs from that of Fig. 4 in that the washing device 510 is placed behind the filter device 520. • In implementation, the filtration device 520 processes droplets/particulate contaminants (including droplets/particles having a particle size of less than 1 micron) in the exhaust gas, and the washing device 510 is connected to the filtering device 520 and is responsible for treating the exhaust gas. The gaseous pollutants such as acid and alkali gases are finally discharged by the gas pumping device 530 to the air treated by the filtering device 520 to the outside of the exhaust gas treating device 500. Although the present invention has been disclosed in a preferred embodiment as above, it is not intended to limit the present invention, and any person skilled in the art can make various changes and retouchings without departing from the scope of the invention. Therefore, the warranty of the present invention is defined by the scope of the patent application.
