Description

Technical Field

[0001] The invention relates to the technical field of organic waste gas treatment, in particular to a catalytic oxidation deodorization system for casting organic waste gas. Background Art

[0002] The production and processing of castings consists of multiple work sections including core making, molding, melting, casting, cleaning and sand treatment (screening). Organic waste gas will be generated in each work section. Organic waste gas not only harms the health of casting production and processing personnel, but also causes serious pollution to the environment.

[0003] At present, organic waste gas is usually treated by combustion, adsorption, absorption and biodegradation. However, the combustion method has disadvantages such as high energy consumption, the adsorption method and absorption method have secondary pollution problems, and biodegradation is not effective in removing aromatic hydrocarbons and sulfur oxides. Therefore, we propose a catalytic oxidation deodorization system for foundry organic waste gas. Summary of the invention

[0004] The object of the present invention is to provide a catalytic oxidation deodorization system for casting organic waste gas, so as to solve the problems of high energy consumption and poor removal effect of the existing method for treating organic waste gas proposed in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A foundry organic waste gas catalytic oxidation deodorization system, comprising:

[0007] An ozone generating mechanism, the output end of which is connected to a mixer through a pipeline, and the input end of the mixer is for organic waste gas to enter;

[0008] A treatment tower, the air inlet end of which is connected to the output end of the mixer through a pipeline, wherein a plurality of catalytic packing layers are arranged from top to bottom in the treatment tower and above the air inlet end, and an anti-blocking spray mechanism is arranged in the inner cavity of the treatment tower between two adjacent groups of the catalytic packing layers; and

[0009] The water tank stores spray liquid, and the liquid outlet end is connected with the anti-blocking spray mechanism through a liquid infusion pipeline and a pump body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1) The present invention allows waste gas and ozone to be mixed in a mixer and then introduced into a treatment tower to react with a catalytic filler layer, oxidatively decompose organic matter in the waste gas, and then absorb the oxidized intermediate products in the waste gas through water spraying, thereby achieving the purpose of catalytic oxidation and deodorization of organic waste gas. This method has a thorough reaction and high removal efficiency, integrates adsorption, oxidative decomposition, water spraying and other processes, has no safety hazards, does not generate hazardous waste, has low operating costs, low energy consumption and is suitable for foundry enterprises;

[0012] 2) The present invention is provided with an anti-blocking spray mechanism, which can effectively prevent the nozzle from being blocked by particulate matter in the organic waste gas and affecting the spray quality. The present invention provides nozzles on both sides of the columnar member. When the nozzle with the liquid outlet facing downward on one side of the columnar member is blocked, the nozzle on the other side can be switched to face downward through the driving device without stopping the machine. After the switch, only the nozzle with the liquid outlet facing downward on the outer wall of the columnar member can spray the spray liquid, thereby reducing the loss of the spray liquid and ensuring the spray quality at the same time.

[0013] 3) The present invention is also provided with a shell, a dredging part and a driving part. When the nozzle on one side of the outer wall of the cylindrical part is clogged, the clogged nozzle can be placed in the shell, and the dredging part is driven by the driving part to dredge the clogged nozzle. There is no need to manually stop the machine and disassemble the nozzle for dredging, thereby improving work efficiency and reducing manual labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The ozone generating mechanism 100 has an output end connected to the mixer 200 through a pipeline, and the input end of the mixer 200 is for the organic waste gas to enter. The ozone generating mechanism 100 is, for example, an ozone generator, and the mixer 200 is, for example, a Venturi mixer. The mixer 200 can mix the casting organic waste gas with ozone to form an organic waste gas containing ozone;

[0028] Alternatively, activated carbon (4-6 mm columnar granular activated carbon) is disposed on the catalytic filler layer 301, and a metal catalyst is loaded on the activated carbon. Of course, the catalytic filler layer 301 is not limited to the above types.

[0029] After the organic waste gas enters the treatment tower 300, it passes through the catalytic packing layer 301 from bottom to top.

[0030] The water tank 500 stores spray liquid, and its liquid outlet is connected to the anti-blocking spray mechanism 400 through an infusion pipeline and a pump body. The anti-blocking spray mechanism 400 sprays the organic waste gas with the spray liquid when the organic waste gas goes upward, and the anti-blocking spray mechanism 400 prevents particles in the upward organic waste gas from clogging the anti-blocking spray mechanism 400 and affecting the spraying effect.

[0031] Preferably, a catalytic packing layer 301 is provided in the water tank 500 of the present embodiment, and the liquid inlet end of the water tank 500 is connected to the liquid outlet end of the treatment tower 300 through a pipeline. The water tank 500 is also connected to the output end of the ozone generating mechanism 100 through a pipeline. The spray liquid sprayed from the treatment tower 300 can absorb excess ozone and intermediate products produced by catalytic oxidation of organic waste gas and flow into the water tank 500, and the ozone generating mechanism 100 also supplies an appropriate amount of ozone into the water tank 500 to cooperate with the catalytic packing layer 301 in the water tank 500 to catalyze the oxidation of organic matter in the spray liquid, thereby improving the treatment quality and facilitating the recycling of the spray liquid.

The outer wall of the transverse section of the connecting frame 405 is provided with a magnetic member 406, and the outer wall of the connecting frame 405 is provided with an elastic member for driving the movable frame 404 to reset. The elastic member is a spring; Figure 3 and attached Figure 4 It can be seen that the nozzle 403 includes a connector that communicates with the liquid channel 402 and a nozzle body that has a diameter larger than the connector and is connected to the nozzle.

When the driving shaft 413 rotates, the driving gear 418 drives the rotating disk 414, and then the magnetic-shaped part 2 on the outer wall of the rotating disk 414 intermittently corresponds to the magnetic part 1 406 in the nozzle 403 in the shell 409, so that the connecting frame 405 intermittently drives the movable frame 404 to allow the insertion needle 407 to enter the liquid outlet of the nozzle 403, and the particles and the like blocked in the liquid outlet of the nozzle 403 are ejected.

[0052] Preferably, both sides of the outer wall of the shell 409 of this embodiment are provided with a sealing mechanism for closing the movable opening, and the sealing mechanism includes: a plurality of sealing plates 426, which are slidably arranged on the outer wall of the shell 409 and correspond to the plurality of movable openings one by one, and two adjacent sealing plates 426 are connected by a connecting rod. The movable opening is closed by the sealing plates 426, so that organic waste gas will not enter the shell 409, and a sealed state is formed in the shell 409; an electromagnetic adsorption member 408 is provided at one end of the outer wall of the shell 409 so that the sealing mechanism moves so that the sealing plate 426 is staggered from the movable opening, toward the electromagnetic adsorption member 408 08 can be embedded with a magnetic piece or the sealing plate 426 can be made of a magnetic material.

The sensor 425 is electrically connected to the electromagnetic adsorption component 408 by the external controller, and the electromagnetic adsorption component 408 contacts the cylindrical component 401. Then, when the cylindrical component 401 is at a preset angle, the sensor 425 receives the signal of the pressure block, so that the external controller does not control the electromagnetic adsorption component 408 to be energized. When the cylindrical component 401 rotates, the push rod 424 separates the pressure block from the sensor 425 under the action of the elastic component. At this time, the sensor 425 does not receive the pressure signal, and then sends a signal to the external controller to control the electromagnetic adsorption component 408 to be energized, so that the sealing plate 426 is staggered from the movable port, so that the nozzle 403 rotates with the cylindrical component 401, and the arc-shaped protrusions 423 on the upper and lower sides correspond to the nozzles 403 on the upper and lower sides respectively.
