Since the fume treatment effects vary, larger treatment tanks are usually used for mixed treatment, resulting in an extremely long fume transport distance, slowing down the air intake speed of the fume and poor transportation effect. Harmful substances are easily deposited in the pipeline during transportation, and the contact effect between the fume and the centralized treatment equipment is poor. In addition, due to the large amount of centralized fume treatment, the surrounding environment of the treated device will be affected by the incompletely filtered fume, thereby affecting the working environment, which has huge defects.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0053] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0054] In one embodiment of the present invention:

[0055] Please refer to the attached Figure 1-7 , comprising a purifier frame 1, on which a mixing group 2 and a capture group 3 are arranged; the mixing group 2 performs secondary return air capture and filtration on the outlet end of the capture group 3, and the industrial waste gas flows to the mixing group 2 after passing through the capture group 3 and is discharged;

[0056] The purifier frame 1 includes a lower mixing box 101 and an upper capturing box 102. The upper capturing box 102 has two sides connected to the fume inlet at the bottom. The fume gas enters the purifier frame 1 from the fume inlet 103 and is pumped and output to the upper capturing box 102 and connected to the mixing group 2. The lower mixing box 101 is provided with a primary filter plate 105 inside.

[0057] The mixing group 2 includes a lateral fan 201, which is arranged on both sides of the upper capture box 102 and is connected to one end of the exhaust gas of the upper capture box 102, and is used to guide the gas downward to the interior of the lower mixing box 101;

[0058] The capture group 3 is fixed inside the purifier frame 1 and filters and intercepts the gas passing through the lower mixing box 101 and the upper capture box 102;

[0059] The air outlet directions of the air outlet ducts of the two lateral air exchangers 201 both act on the interior of the lower mixing box 101, but the positions of the two air outlets are not symmetrical about the midline layer of the purifier frame 1;

[0060] Please refer to Figure 1-4 , Figure 7 The top of the purifier frame 1 has an arc-shaped air outlet cabin 115, and the two side fans 201 are fixed on both sides of the arc-shaped air outlet cabin 115 and are connected to the arc-shaped air outlet cabin 115. The lower parts of the side fans 201 on both sides are connected with guide air ducts 202, and the gas outlet ends of the two guide air ducts 202 extend downward into the lower mixing box 101.

[0061] Side arc guide plates 109 are provided on both sides of the primary filter plate 105, and the arc guide plates are used to guide the air of the guide air duct 202 to be mixed into the interior of the purifier frame 1. When the two side air exchangers 201 continue to work, a gas turbulence mixing effect can be formed inside the lower mixing box 101;

[0062] An oil collecting hopper 104 is provided at the bottom of the purifier frame 1. The interior of the oil collecting hopper 104 is where the smoke inlets 103 on both sides gather. It bears the impact of the smoke on both sides. The sticky oily substances will be dispersed and gathered in the oil collecting hopper 104, and the filtered oil at the bottom of the filter groove 106 will also fall into the oil collecting hopper 104. The bottom of the oil collecting hopper 104 is connected to a discharge pipe for removing the deposited oil.

[0063] The flue gas enters the bottom oil collecting hopper 104 from the flue gas inlet 103 on both sides of the lower mixing box 101 to produce a counter-flow. The air filter slot 106 is a device with filtering and intercepting structures on all four sides. In the process of airflow counter-flow, the air filter slot 106 can have a certain interception effect and pass the flue gas upward; the upper diffuser 107 is a groove that is concave downward. The flue gas rising from the air filter slot 106 will not be disturbed by the turbulence on both sides at first, and has a straight airflow section. With the exhaust fan 117, it can guide the upward movement of the airflow. The flue gas in the lower mixing box The position of the combining box 101 is mixed with the return air of the lateral fan 201 to produce a concentration dilution effect, and is in tangential and straight line collision contact with the bottom of the capture group 3, thereby increasing the contact effect between the smoke and the intercepted part. The smoke passes through the capture group 3's liquid collection, attachment, capture, and filtration and is discharged through the exhaust fan 117. Part of the exhaust air is then discharged again by the lateral fan 201 into the lower mixing box 101 for air mixing, thereby reducing the concentration of harmful substances in the air filtered by the original filter slot 106 and reducing the removal of harmful substances from the exhaust fan 117 outlet.

[0064] In one embodiment of the present invention:

[0065] The capture group 3 is installed on the upper part of the lower mixing box 101 near the upper capture box 102. The top of the purifier frame 1 is provided with an exhaust fan 117. The capture group 3 includes

[0066] The air filter slot 106 is fixedly connected to the primary filter plate 105 to initially filter smoke and dust gas in cooperation with the suction force of the exhaust fan 117;

[0067] The oil collecting group is fixed on the inner wall of one end of the lower mixing box 101 close to the upper capturing box 102, and is used to intercept and capture the fluid that can flow and settle;

[0068] A filter group, fixed to the top of the upper capture box 102, is used to capture the non-gaseous substances that can stick to the smoke and filter the gas;

[0069] The interior of the purifier frame 1 is a stable pressure space with a separate inlet and outlet from the primary filter plate 105 to the top. The shutter effect in the figure is an unnecessary device that can be opened and closed, and cannot define a constant air space inside the device and a constant airflow inlet and airflow outlet flux. In the present invention, the inlet and outlet wind directions are only the smoke inlet 103 into the arc-shaped outlet and the lateral through slot 116 out.

[0070] Please pay attention to Figure 2 , Figure 3The central area of ​​the primary filter plate 105 is provided with an upper diffuser 107 that sinks downward. The air filter groove 106 is fixed to the central area of ​​the upper diffuser 107 and connects the upper and lower spaces of the primary filter plate 105. The upper diffuser 107 is a downwardly concave groove. The smoke rising from the air filter groove 106 will not be disturbed by the turbulence on both sides at first. It has a straight airflow section, and can guide the upward movement of the airflow in conjunction with the exhaust fan 117.

[0071] In another embodiment of the present invention:

[0072] Please pay attention to Figure 1-4 The oil collecting group includes

[0073] The oil collecting transverse groove 110 is fixed to the inner wall of the lower mixing box 101, and has a groove on its upper surface;

[0074] The pallet frame 111 includes a plurality of concave pallet grooves 112 and an upper concave pallet groove 113. The grooves of the concave pallet grooves 112 and the upper concave pallet grooves 113 face opposite directions and are close to each other.

[0075] The support frame 111 is distributed obliquely, and the lower oblique end of the support frame 111 is fixed to the upper edge of the oil collecting horizontal groove 110;

[0076] Both ends of the support frame 111 are fixed to the purifier frame 1;

[0077] The intervals between the two adjacent concave support plate grooves 112 and the two adjacent upper concave support plate grooves 113 are evenly arranged, and the upper and lower adjacent concave support plate grooves 112 and upper concave support plate grooves 113 are staggered in a top view;

[0078] Since the flue gas at the bottom has a mixing effect and can form a tangent intersection with the bottom surface of the pallet frame 111, the two lower concave pallet grooves 112 and upper concave pallet grooves 113, which are one above the other, facing opposite directions and staggered, can form the following effects: the side wings of the lower concave pallet grooves 112 that are concave upward can guide the smoke to contact the upper concave pallet grooves 113, and the two side plates of the upper concave pallet grooves 113 will again guide the smoke to the lower sides to the lower concave pallet grooves 112, and at the same time guide the accumulated liquid to the lower groove so as to aggregate to the oil collecting transverse groove 110. This process forms at least three contact impacts on the smoke, which can effectively improve the retention effect of harmful particles.

[0079] Please pay attention to Figure 4-7 The filter group includes

[0080] A gas capture tray 301, wherein the gas capture tray 301 is fixed on the top of the lower mixing box 101, and the upper layer thereof is located inside the upper capture box 102. A plurality of sleeve air ducts 303 distributed in two rows are arranged above the gas capture tray 301, and the bottoms of the sleeve air ducts 303 all have slotted circular channels 302. A reinforcing rib 304 is arranged on the gas capture tray 301 between the two rows of the sleeve air ducts 303, and a spray pipe 305 is fixed on the reinforcing rib 304. A plurality of nozzles 306 are arranged on both sides of the spray pipe 305, and a single nozzle 306 corresponds one-to-one to the sleeve air duct 303;

[0081] The catcher 307 is located above the gas capture tray 301. The catcher 307 corresponds to the annular air duct 303 one by one. The nozzle 306 is located between the bottom height of the catcher 307 and the ring height of the annular air duct 303. The spray direction of the nozzle 306 is toward the capture area of ​​the catcher 307. The catcher 307 includes a capture motor 308 fixedly connected to the upper capture box 102 and a multi-link capture plate 309;

[0082] A filter element 310, wherein the filter element 310 is fixed inside the upper capture box 102 and is located above the capture device 307, and the upper part of the filter element 310 is connected to the air inlet direction of the exhaust fan 117;

[0083] The present invention separates two functional areas from the internal space of the purifier frame 1, and utilizes a small enclosed space to extract air volume, which can improve the flow effect of the internal gas and make the guiding effect smoother. The multi-level distributed capture group 3 screens and filters the intersection of the two functional areas of the sealed box purifier frame 1, and cooperates with the mixing effect of the lower mixing box 101 area to enable the mixed gas to interact with the capture group 3, thereby improving the smoke capture effect of the capture group 3. The working method of the capture group 3 is as follows: the smoke passes through the support frame 1 After the contact interception of the 11 components, it enters the capture range of the catcher 307 (the main action range of the exhaust fan 117) through the circular channel 302. At this time, the spray pipe 305 continues to work, and atomized spray attachment and capture is performed between the bottom of the catcher 307 and the height of the ring air duct 303. Granular harmful substances and steam-like water condensation substances are attached by the spray fluid, thereby improving the interception effect of the catcher 307. The smoke passing through the catcher 307 is filtered by the filter element 310 and then discharged to the arc-shaped air outlet cabin 115 for easy discharge.

[0084] Please pay attention to Figure 1 , Figure 3The top of the purifier frame 1 is provided with a top support 114, the exhaust fan 117 is fixed inside the top support 114, the arc-shaped air outlet cabin 115 is arranged on one side of the top support 114, and the upper part of the arc-shaped air outlet cabin 115 is provided with an upper circular screen plate 120;

[0085] An air outlet baffle 118 is provided on one side of the top support platform 114 near the arc-shaped air outlet chamber 115, and one side of the air outlet baffle 118 is connected to the air outlet of the exhaust fan 117;

[0086] The side of the arc-shaped air outlet compartment 115 is provided with a lateral through slot 116 connected to the air inlet end of the lateral fan 201 .

[0087] The main air intake source of the side fan 201 is the safe smoke that has been filtered once and part of the surrounding air. The return air treatment is equivalent to optimizing the surrounding area of ​​the purifier frame 1 at the same time. After the guide air duct 202 is discharged into the lower mixing box 101, it can produce a mixing effect and a dilution effect inside the lower mixing box 101, increase the concentration of harmful air inside the purifier frame 1, reduce the interception and capture pressure of the device at the limit, and help to extend the maintenance and cleaning cycle of the device.
