Generally, The exhaust gas often contains harmful substances such as particulate pollutants, sulfur oxides, hydroxides and the like. Early factories used chimneys to directly discharge exhaust gas into the sky. In today's environmental awareness, most factories will install purification equipment to reduce the amount of harmful substances in the exhaust gas.

However, the equipment used to purify the exhaust gas is installed at the beginning of the plant construction according to the needs of the time. When the exhaust gas purification equipment is installed, it is found that the purification effect is not good, the fault is used after a period of use, or the plant is not considered for purification at the initial stage of construction. At the time of demand, it is difficult to install a device for improving the exhaust gas emission quality of an existing exhaust gas purifying device or a chimney. The way to improve often requires re-planning and rebuilding the plant. This will not only result in improved cost, improved time, but also the time and cost of the plant operation. Therefore, how to change the original equipment and reduce the possibility of work safety. In the case of improving the quality of exhaust gas emissions, it is an issue that needs to be improved in the field.

Accordingly, it is an object of the present invention to provide an exhaust gas purification apparatus that can improve at least one of the disadvantages of the prior art.

The waste water recovery tank 231 has an inclined wall 235 located below the net smoke passage 210, the inclined wall 235 having a water column splashing surface 236 facing the outlet 217 of the net smoke passage 210, and each of the net smoke modules 21 There is also a draft fan 24 mounted at the exhaust vent 218 to assist in the evacuation, but the present invention is not necessary to have the extractor 24.

In the present embodiment, the exhaust gas purification device of the exhaust gas discharge unit 1 is connected to an exhaust gas generating device (not shown), that is, the exhaust gas generated by the exhaust gas generating device enters the exhaust gas via the inlet pipe 12 Inside the tube 11. During the passage of the exhaust gas through the inlet pipe 12, since the inlet pipe 12 is connected to a plurality of the net smoke units 2, some exhaust gas is captured before the exhaust gas enters the exhaust pipe 11, and the rest is The exhaust gas enters the exhaust pipe 11, and the first smoke collecting port 223 of each of the remaining net smoke units 2 not only extends into the exhaust pipe 11, but also is disposed at different heights, so most of the The exhaust gas will be captured by the net smoke unit 2, and finally enter the corresponding net smoke unit 2 respectively. Since the present invention is provided with the pumping motor 222 on each of the first tobacco traps 221, the exhaust gas can be quickly Entering the net smoke passages 210.

When the exhaust gas enters the communication section 216 of the net smoke passage 210 of each of the net smoke units 2, it will float upward into the separation sections 215. On the other hand, the waste water pump 234 of the waste water recovery module 23 of each of the net smoke units 2 operates, and the liquid located in the waste water tank 230 is sent to the water distribution tray 232 via the recovery pipe 233, and finally The water spray holes 214 of the water spray pipes 213 are sprayed to the corresponding partition sections 215 to flush the exhaust gas entering the partition sections 215.

Since the water is pressurized and ejected by the water spray hole 214 of each of the water spray pipes 213, the water column is sprayed to the inner surface of the corresponding partitioning section 215, and when the exhaust gas encounters the water column, for example, the exhaust gas : particulate contaminants, harmful substances, etc. are washed by water, and then splashed on the water column splashing surface 236 of the waste water recycling tank 231, and the excited water spray can be contacted again with the exhaust gas to enhance water molecules and The contact opportunity of the exhaust gas improves the effect of purifying the exhaust gas, and the water containing the harmful substances will flow into the waste water tank 230, and the purified air is discharged from the exhaust port 218 of each net smoke unit 2, so that the source is continuously Operation, you can continuously filter harmful substances in the exhaust gas to achieve the purpose of improving the quality of exhaust emissions. In the embodiment, the waste water purifier 238 for filtering waste water is disposed on the waste water recovery module 23, so that the waste water can have better quality when continuously used in a source, and the water temperature regulator can be used to change the temperature of the water (for example, adjustment) Up to 70 ° C), to use the temperature change to improve the flushing effect, while keeping the exhaust gas at a high temperature and smooth upward flow.

Referring to Figures 4 and 5, a second embodiment of the present invention provides an exhaust gas discharge unit 1 and the net smoke unit 2, the exhaust gas discharge unit 1 also including the exhaust passage 10 and the row. The smoke pipe 11 , each of the net smoke units 2 includes the net smoke module 21 located outside the exhaust passage 10 , and the exhaust gas capture module that sends the exhaust gas through the exhaust passage 10 to the net smoke module 21 22. Each of the net smoke modules 21 has a net smoke holder 211 defining the net smoke passage 210, a water spray pipe 213 extending into the net smoke passage 210, and a water supply port 214 installed at the smoke exhaust port 214. The draft fan 24 also has the water spray hole 214. The exhaust gas capture module 22 has at least one second tobacco trap 221' in addition to the first tobacco trap 221, and the at least one second tobacco trap 221' has a second smoke trap 223'. The first tobacco collecting pipe 221 and the second tobacco collecting pipe 221' are spaced along the longitudinal direction of the net smoke holder 211, whereby exhaust gas of different heights on the exhaust passage 10 can be captured to increase the amount of exhaust gas captured.

When the exhaust gas purifying device of the second embodiment of the present invention is in use, the first and second tobacco traps 221, 221' of each of the net smoke units 2 can capture the exhaust gas passing through the exhaust passage 10 and will capture The exhaust gas is sent into the net smoke holder 211, and the water spray pipe 213 of each net smoke unit 2 can also spray a water column to flush the exhaust gas. Therefore, the second embodiment of the present invention can also reach the first embodiment. The efficacy described. It should be noted that the second embodiment of the present invention can also provide a waste water recovery module at the bottom of the net smoke holders 211 to facilitate recovery and reuse of wastewater.

It can be seen from the above description that the exhaust gas purifying device of the present invention can provide the net smoke unit 2 outside the exhaust gas discharge unit 1 according to the needs of use without destroying the original equipment, and let each of the clean smoke units The first and second smoke traps 223, 223' of the second exhaust gas inlet 223, 223' extend into the exhaust passage 10 of the exhaust gas discharge unit 1 to capture the exhaust gas, and then sent to the outside of the exhaust gas passage 10 to perform the purification operation of the exhaust gas. The foregoing net smoke unit 2 is not only very suitable for installation on the existing exhaust gas discharge unit 1, but when one of the clean smoke units 2 fails, not only does it prevent the exhaust gas from being discharged upward, the net smoke unit 2 thereof The remaining ones can also exert a good net smoke effect. Since the first and second smoke collecting ports 223, 223' of each of the net smoke mold units 2 of the present invention do not hinder the exhaust gas from flowing upward from the bottom of the smoke exhaust passage 10, even if the exhaust gas discharge device fails, It also does not affect the effect of exhaust gas passing through the exhaust passage 10 and discharging, so as to reduce possible work safety problems. Therefore, the present invention can achieve the effect of improving the quality of the exhaust gas without changing the original equipment and avoiding the problem of work safety. Therefore, the present novel is indeed an exhaust gas purifying device with novel structure and industrial utilization value.
