Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-3, a chemical waste gas extraction device, includes base 1, and circular slot 2 has been seted up to the lateral wall of base 1, installs extraction fan 4 in circular slot 2, and the mounting means of extraction fan 4 is current mature technique, does not specifically describe.
Fixedly connected with arc piece 41 on one of them flabellum of suction fan 4, and arc piece 41 closely laminates with the inner wall of circular slot 2, and air inlet 22 has been seted up to the inner wall of circular slot 2, it should explain that, the upper surface of arc piece 41 is greater than the bore of air inlet 22 to guarantee that arc piece 41 is rotating to just to the time with air inlet 22, arc piece 41 can stop up air inlet 22 completely, has good gas tightness.
The first cylinder 5 and the second cylinder 6 are made of heat conducting rubber with good elasticity, so that the heat conducting rubber not only has good elasticity, but also has excellent heat conducting capability, and can rapidly transfer heat inside the second cylinder 6 to the radiating fins 61 and radiate the heat through the radiating fins 61.
The liquid guide tube 7 is provided with a first check valve 71, and the condensation pipe 8 is provided with a second check valve 81. it should be noted that the first check valve 71 only allows the cooling liquid to flow from the first cylinder 5 to the second cylinder 6, and the second check valve 81 only allows the cooling liquid to flow from the second cylinder 6 to the first cylinder 5.
In this embodiment, the extraction of chemical waste gas can be carried out in the start-up extraction fan 4, and when the extraction fan 4 rotated, the arc piece 41 also rotated thereupon together, so the arc piece 41 will intermittent type nature block up gas outlet 21 for the waste gas of discharging into in the conveyer pipe 3 is the pulsiveness.
When the arc block 41 is moved away, the extracted exhaust gas rushes into the delivery pipe 3 together, so that the air pressure in the delivery pipe 3 is increased instantaneously, the elastic first cylinders 5 on the two sides of the inner wall of the delivery pipe 3 are squeezed, the first cylinders 5 contract and collapse, and under the flow limiting effect of the first check valve 71 and the second check valve 81, the cooling liquid in the first cylinders 5 flows into the second cylinders 6 along the liquid guide pipe 7, and the second cylinders 6 are expanded.
When the arc piece 41 blocks up the air outlet 21, the air pressure in the conveying pipe 3 recovers, the second cylinder 6 recovers therewith, and the cooling liquid flowing into the second cylinder 6 flows back to the first cylinder 5 along the condensation pipe 8 again, so that the cooling liquid can flow in the condensation pipe 8 in a one-way circulating manner in the rotation process of the exhaust fan 4, so that the heat in the waste gas in the conveying pipe 3 can be quickly taken out of the conveying pipe 3, and the heat can be dissipated out through the radiating fins 61, so that the high temperature is prevented from damaging the waste gas treatment equipment at the conveying terminal. Particularly, in the manufacturing process, a plurality of first cylinders 5 and second cylinders 6 can be arranged inside and outside the conveying pipe 3 at equal intervals, and the heat dissipation efficiency is improved.
Example two:
referring to fig. 4, a difference from the first embodiment is that one of the blades of the exhaust fan 4 is made of a magnetic material, the side wall of the base 1 is provided with a liquid storage tank 9, and the side wall of the base 1 is provided with a water filling port communicated with the liquid storage tank 9, so as to conveniently add water into the liquid storage tank 9.
Equal fixedly connected with strip 10 that absorbs water on two relative inner walls of air inlet 22, and strip 10 that absorbs water extends to in the reservoir 9, fixedly connected with iron shake spring 11 between two strip 10 that absorb water, and shake spring 11 on the surface fixedly connected with the strip 10 that absorbs water linked to, the fine hair that absorbs water and strip 10 all adopt polymer water-absorbing resin, hydrophilic group that its structure has gives its extremely strong hydroscopicity to can all obtain timely replenishment after guaranteeing that the water on the fine hair that absorbs water is shaken off.
In this embodiment, a proper amount of water may be added into the liquid storage tank 9, and under the capillary action, the water in the liquid storage tank 9 will rise along the water absorption strip 10 to the water absorption wool on the surface of the vibrating spring 11.
When the suction fan 4 rotates, the magnetic blades on the suction fan 4 are continuously close to and far away from the vibration spring 11, under the action of magnetic force, the vibration spring 11 extends towards the magnetic blades when being close to the magnetic blades, when the magnetic blades rotate to a position far away from the vibration spring 11, the vibration spring 11 resets and simultaneously generates vibration, and water on the water absorption wool of the vibration spring 11 is shaken off and smashed into small water drops.
The small water drops which are broken can be fully contacted with the waste gas, and quickly absorb the heat in the waste gas to be evaporated, so that the temperature of the waste gas can be greatly reduced, and the temperature of the waste gas discharged into the waste gas treatment equipment is further reduced. In addition, the small water drops can also form condensation nuclei with other fine impurities such as dust in waste gas, the condensation nuclei have large mass and cannot rise along with air flow, and therefore the condensation nuclei fall to the bottom in the circular groove 2 under the action of gravity, so that the damage to equipment caused by the fact that other fine impurities such as dust enter waste gas treatment equipment can be avoided, and only the circular groove 2 needs to be cleaned regularly.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
