Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the utility model provides a rubbish transfer station negative pressure deodorizing device, including the tower body 1, be fixed in the outer liquid reserve tank 2 of tower body 1, be fixed in drawing liquid pump 3, shower 4 on the liquid reserve tank 2, set up in the tower body 1 and certainly the tower body 1 bottom is close to the first board-like hydrophone 51, first filling layer 61, the first layer 71 that sprays, the board-like hydrophone 52, the second filling layer 62 of receiving of second, second spray layer 72, the board-like hydrophone 53 and the third filling layer 63 of receiving of third of the orientation at the top of tower body 1 interval sets gradually.

The tower body 1 is provided with an air inlet 11, an air outlet 12 and a plurality of inspection windows 13, the air inlet 11 is located below the first plate-type water collector 51, and the air outlet 12 is located at the top of the tower body 1 in the up-down direction of the tower body 1. The liquid pump 3 is configured to pump the liquid contained in the liquid storage tank 2 into the spray pipe 4, each of the first filling layer 61, the second filling layer 62, and the third filling layer 63 includes a plurality of multi-surface hollow spheres 64, each of the first spray layer 71 and the second spray layer 72 includes a plurality of spray heads 8, and each of the spray heads 8 is connected to the spray pipe 4 and configured to spray the liquid pumped from the liquid storage tank 4 downward.

The liquid storage tank 2 is used for containing water or liquid medicine which is diluted and prepared in proportion, and can be correspondingly prepared according to the type of gas to be treated, for example, dilute sulfuric acid liquid can be contained in the liquid storage tank 2 mainly for alkali absorption, and sodium hydroxide liquid can be contained in the liquid storage tank 2 mainly for acid absorption. Specifically, in the present embodiment, the storage tank 2 contains a garbage microorganism deodorant solution, which is prepared by diluting a garbage microorganism deodorant (see the chinese patent 201710812815.X) in a certain proportion, and can effectively degrade ammonia and hydrogen sulfide gas and effectively eliminate odor. Of course, the water can also effectively adsorb the waste gas in the odor.

The air inlet 11 may be connected to a fan or a waste gas discharge pipeline, specifically, in this embodiment, the air inlet 11 is connected to a fan (not shown), and the fan pumps the odor in the waste transfer station into the tower body 1 through the air inlet 11, so as to guide the odor to the inside of the tower body 1 for treatment. The odor sequentially passes through the first plate-type water collector 51, the first filling layer 61, the first spraying layer 71, the second plate-type water collector 52, the second filling layer 62, the second spraying layer 72, the third plate-type water collector 53 and the third filling layer 63 from bottom to top, and is discharged out of the garbage transfer station through the air outlet 12. The garbage microorganism deodorization liquid flows to the bottom of the tower body 1 from top to bottom after being sprayed downwards by the spray heads 8 of the first spray layer 71 and the second spray layer 72. The ascending odor and the descending garbage microorganism deodorization liquid are continuously contacted in the filling layer and the plate-type water collector, and the ascending odor is continuously degraded and absorbed and completely meets or even exceeds the discharge requirement when reaching the air outlet. The first plate type water collector 51, the second plate type water collector 52 and the third plate type water collector 53 have large surface areas, can collect water mist in the air, generate a large amount of water films, promote full contact of gas phases, and can condense water drops to enable the water drops to fall and recycle; the polyhedral hollow spheres 64 filled in the first filling layer 61 and the second filling layer 62 improve the surface area, improve the mass transfer rate, provide good warm and humid performance and facilitate the uniform distribution of gas flow, thereby further promoting gas phase contact. The third packing layer 63 can be used for aerosol separation to remove water mist in the air. And after the odor in the garbage transfer station is sucked into the tower body 1 by the fan, a large amount of fresh air outside enters the garbage transfer station under the action of negative pressure, so that the deodorization effect is further improved.

In this embodiment, inspection window 13 is a plurality of, distributes in the different positions of tower body 1, can be used to the feeding, unload, observe, overhaul etc. also makes things convenient for the clearance of the filth in tower body 1 bottom simultaneously.

In this embodiment, the negative pressure deodorizing device of the waste transfer station further includes a plurality of activated carbon filter screens 121 fixed in the air outlet 12. Thereby, neither hinder gaseous passing through, can also further promote the deodorization effect, and have the function of getting rid of harmful gas concurrently.

Specifically, the activated carbon filter screen 121 is 2 layers, parallel to the air outlet 12 and spaced apart from each other. Therefore, not only the cost is considered, but also the deodorization effect is improved, and the replacement period is reduced.

In this embodiment, the filling layer further includes raschig rings (not shown), that is, the filling materials of the first filling layer 61, the second filling layer 62 and the third filling layer 63 include the polyhedral hollow spheres 64 and the raschig rings, so as to further increase the surface area, and achieve better degradation, deodorization and drying effects.

In this embodiment, the spray pipe 4 includes a first branch pipe 41 configured to the first spray layer 71 and a second branch pipe 42 configured to the second spray layer 72, and both the first branch pipe 41 and the second branch pipe 42 are provided with an on-off valve 9. Therefore, the spray heads 8 of the first spray layer 71 and the second spray layer 72 can be controlled to work by controlling the switch valve 9, and the spray heads 8 of the first spray layer 71 and the second spray layer 72 can spray together or independently according to needs, so that the spray efficiency is optimized.

In this embodiment, one side top intercommunication of liquid reserve tank 2 has overflow pipe 22, and the bottom intercommunication has blow off pipe 21, overflow pipe 22 with all be provided with ooff valve 9 on the blow off pipe 21. Therefore, the liquid medicine in the liquid storage tank 2 can be effectively prevented from overflowing, and the waste liquid can be regularly cleaned from the negative pressure deodorization device of the garbage transfer station.

In this embodiment, the number of the heads 8 of the first spray layer 71 and the second spray layer 72 is 3. Therefore, not only the cost is considered, but also the spraying effect is ensured.

Referring to fig. 3, in the first spraying layer 71 and the second spraying layer 72, the connection lines between the spray heads 8 on the same layer form an equilateral triangle, and the center of the equilateral triangle is located on the central axis of the tower body 1. Thereby, spray more evenly, gaseous phase contact effect is better, and the deodorization effect is better.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
