Description

Technical Field

[0001] The invention relates to the technical field of hazardous waste odor treatment, and in particular to a deodorization and treatment device for a hazardous waste incineration pit. Background Art

[0002] Hazardous waste incineration is one of the main means of harmless treatment of hazardous waste. Since hazardous waste is directly exposed to the air in the pit, there are many types of hazardous waste, complex components, high organic content, and the odor components generated by the waste are complex and strong. Gases such as hydrogen sulfide, ammonia, hydrogen chloride, alcohols, aldehydes, benzene series and hydrocarbon compounds are directly volatilized into the surrounding environment, which are toxic and highly irritating. If not handled in time, there are great safety hazards and environmental risks.

[0003] The current incineration pit workshop has added an odor collection and deodorization system. The odor is discharged into the atmosphere after being treated to meet the standards. The conventional treatment process section is relatively simple. During the actual operation of the simple pipeline of the collection system, too much smoke and dust will accumulate on the pipe wall at the bottom, resulting in poor heat dissipation effect of the pipeline, affecting flue gas collection and easy clogging. After spraying by the alkaline desulfurization tower, the large particles of debris contained in the smoke and dust are settled to the bottom of the desulfurization tower and need to be cleaned in time to avoid recycling with water, which will cause clogging of the water supply pipe. Finally, the flue gas meets the emission standards after deodorization by activated carbon adsorption, but the activated carbon is not easy to replace, and the adsorption effect is poor due to long-term use.

At the same time, it avoids close contact with the adsorption tower and reduces the damage caused by dangerous exhaust gas.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention sets a desulfurization mechanism, and the flue gas of hazardous waste enters the desulfurization mechanism through the air intake pipe. The spray pipe sprays the desulfurizer into the packing layer to perform dust reduction and desulfurization treatment on the flue gas. The large particles of debris in the smoke follow the desulfurizer and flow downward to the scraping component for filtration, so that the desulfurizer and the debris are isolated and recovered separately. The desulfurizer flows out from the drain pipe, which is beneficial to the recycling and reuse of the desulfurizer and saves resources. When the debris on the scraping component accumulates to a certain extent, the collected debris is cleaned into the collecting component, which is beneficial to ensure the filtering effect and clean the inner wall of the desulfurization tower. The spray component cleans the dust inside the air intake pipe to avoid affecting the pipeline from transporting the incineration flue gas into the desulfurization tower, and at the same time ensures that the inner wall of the pipeline is clean, which is beneficial to the heat dissipation of the pipeline.

[0014] 2. The present invention provides a spraying assembly, and the nozzle is connected to a spiral tube. The spiral tube conveys desulfurizer to the nozzle, and the flue gas near the desulfurization tower is sprayed first, which is beneficial to flushing large particles of dust remaining at the bends of the pipeline. At the same time, the flue gas is initially cooled down to protect the pipeline, extend the service life of the pipeline, and reduce the probability of dangerous exhaust gas leakage caused by pipeline corrosion. It is convenient for the dehydration assembly to scrape, clean and collect dust adhered to the inner wall of the pipeline, and prevent the dust from following the air flow and becoming difficult to clean.

[0015] 3. The present invention sets a scraping component. The first motor drives the two groups of first scrapers to rotate on the surface of the screen plate in a direction close to each other. The connecting rod is set to avoid the receiving plate. The receiving plate passes through the screen plate, and its outer wall is socketed with the inner wall of the screen plate, so that there is a dead angle in the cleaning of the screen plate. The connecting rod is set so that the fixed block follows the first scraper to rotate to the receiving plate and fits with the side of the receiving plate, so as to avoid blockage caused by inadequate cleaning of both sides of the receiving plate, which affects the use of the screen plate. The fixed block drives the wiping block to fit closely to one end of the inner wall of the desulfurization tower. The wiping block is made of sponge and has elastic force. Since the screen plate is set at an angle, the wiping block is easy to produce a gap with the inner wall of the desulfurization tower during rotation. Therefore, a material with a large deformation amount is used. A plurality of wiping blocks are set, which are lengthened from top to bottom, which is conducive to fitting to the inner wall of the desulfurization tower and gathering the debris on the surface of the screen plate to be collected and shoveled out.

[0016] 4. The present invention sets a collecting component. When the desulfurization tower is working, the telescopic column drives the baffle to block the outer wall of the desulfurization tower to prevent the dangerous exhaust gas from escaping and causing air pollution that endangers the health of the workers. When debris needs to be cleaned, the baffle is opened, the sliding seat is rotated to be horizontally fixed, the first telescopic rod is extended, and the scraper is driven to contact the surface of the sieve plate to scrape the debris on the sieve plate into the collection tank. The scraper rotates to fit the surface of the sieve plate more closely. After cleaning, the baffle is closed and the desulfurization work is continued to assist in cleaning the sieve plate to prevent the sieve plate from being blocked and causing the desulfurizer to flow back to the intake pipe too slowly, affecting the flue gas desulfurization effect.

[0017] 5. The present invention sets a containing component. During the activated carbon adsorption process, the vibrating head vibrates the containing tank to make the activated carbon fully contact with the flue gas, thereby improving the adsorption effect. After the activated carbon is inactivated, the discharge pipe is opened to discharge the inactivated activated carbon from the discharge pipe, and the second motor drives the second scraper to rotate, and cooperates with the vibrating head to drive the containing tank to vibrate, thereby assisting the activated carbon to be discharged quickly. After discharge, the loading pipe mouth is opened to pour the activated carbon in the activated carbon storage box into the containing tank. The rotation of the rotating shaft drives the containing tank to rotate, so that the activated carbon is evenly covered, which is convenient for loading and unloading of the activated carbon. The activated carbon in the activated carbon storage box prolongs the replacement time and reduces the workload of the staff. At the same time, it avoids close contact with the adsorption tower and reduces the damage caused by dangerous exhaust gas.

[0018] 6. The present invention sets a dehydration component. When cleaning is needed, the second telescopic rod is extended to drive the sponge head to contact the inner wall of the air inlet pipe tightly, and the dust particles adhered to the inner wall are wiped off. The sponge head performs spiral motion in the pipeline, scrapes from the nozzle end to the inside of the desulfurization tower, and cleans the debris onto the sieve plate. At this time, the second telescopic rod is retracted, and the clamping plates on both sides of the sponge head are squeezed close to each other under the action of the second spring, and the desulfurizer absorbed on the sponge head is squeezed out, filtered through the sieve plate and then concentrated to the bottom of the desulfurization tower. Cleaning the inside of the pipeline is beneficial to protecting the pipeline, avoiding corrosion by dangerous gases, and extending the service life of the pipeline. Squeezing the sponge head to keep the sponge head clean is beneficial to improving the cleaning effect of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The desulfurization mechanism 1 includes a desulfurization tower 101, the inner wall of the desulfurization tower 101 is fixedly connected with a spray pipe 102, a packing layer 103 is arranged below the spray pipe 102, the outer wall of the packing layer 103 is fixedly connected to the inner wall of the desulfurization tower 101, the outer wall of the desulfurization tower 101 is fixedly connected with an air inlet pipe 104, the inner wall of the air inlet pipe 104 is provided with a spray assembly 105, the outer wall of the spray assembly 105 is fixedly connected to the bottom of the inner wall of the desulfurization tower 101, and the spray assembly 105 is fixedly connected to the inner wall of the desulfurization tower 101. The outer wall of the spraying assembly 105 is slidably connected with a dehydration assembly 109, the outer wall of the spraying assembly 105 away from the inlet pipe 104 is provided with a scraping assembly 106, the outer wall of the scraping assembly 106 is fixedly connected to the inner wall of the desulfurization tower 101, the outer wall of the desulfurization tower 101 is fixedly connected to the end close to the inlet pipe 104 with a collecting assembly 107, the collecting assembly 107 is arranged below the inlet pipe 104, the outer wall of the desulfurization tower 101 is fixedly connected to the end close to the inlet pipe 104 A drainage pipe 108 is fixedly connected, and the flue gas of hazardous waste enters the desulfurization mechanism 1 through the air intake pipe 104. The spray pipe 102 sprays the desulfurizer into the packing layer 103 to reduce dust and desulfurize the flue gas. The large particles of debris in the smoke follow the desulfurizer and flow downward to the scraper component 106 for filtration, so that the desulfurizer and the debris are isolated and recovered separately. The desulfurizer flows out from the drainage pipe 108, which is conducive to the recycling and reuse of the desulfurizer and saving resources. When the debris on the scraper component 106 accumulates to a certain extent, the collected debris is cleaned into the collection component 107, which is conducive to ensuring the filtering effect and cleaning the inner wall of the desulfurization tower 101. The spray component 105 cooperates with the dehydration component 109 to spray the dust inside the air intake pipe 104, so that it is adsorbed to the inner wall of the air intake pipe 104, which is easy to clean and avoids affecting the pipeline from transporting the incineration flue gas to the desulfurization tower 101. At the same time, the inner wall of the pipeline is kept clean and tidy, which is conducive to the heat dissipation of the pipeline.

[0033] The activated carbon adsorption mechanism 5 includes an adsorption tower 501, the inner wall of the adsorption tower 501 is fixedly connected with a holding component 502, the outer wall of the adsorption tower 501 is fixedly connected with a feeding pipe 503, and the end of the feeding pipe 503 away from the adsorption tower 501 is fixedly connected with an activated carbon storage box 504. After the gas is adsorbed by the activated carbon, it is discharged from the exhaust pipe 6. After a period of use, the activated carbon is easily deactivated and affects the adsorption effect. The holding component 502 discharges the inactivated activated carbon, and then the activated carbon in the activated carbon storage box 504 is fed to the holding component 502 through the feeding pipe 503, and the inside of the holding tank 5021 is filled and re-adsorbed. When manually replenishing the feeding, it is only necessary to replenish the activated carbon storage box 504, which reduces the contact between the staff and the adsorption tower 501, reduces the harm of dangerous exhaust gas to the staff, makes loading more convenient, extends the time for replenishing activated carbon, and reduces the workload.

The spraying pipe 102 sprays the desulfurizer into the packing layer 103 to reduce dust and desulfurize the flue gas. The large particles of debris in the smoke follow the desulfurizer and flow downward to the scraping component 106 for filtration, so that the desulfurizer and the debris are isolated and recovered separately, which is beneficial to the recycling and reuse of the desulfurizer. When the scraping component 106 accumulates to a certain extent, the collected debris is cleaned into the collecting component 107, and the inner wall of the desulfurization tower 101 is cleaned. The spraying component 105 cleans the dust inside the air intake pipe 104 to avoid affecting the pipeline from transporting the incineration flue gas to the desulfurization tower 101, and at the same time ensures that the inner wall of the pipeline is clean, which is beneficial to the heat dissipation of the pipeline. The waste gas after desulfurization treatment enters the UV photocatalytic device 3 for treatment, removes small-size particles in the waste gas, quickly and effectively decomposes organic matter, and can effectively decompose the organic components in the gas. Then the waste gas enters the activated carbon adsorption mechanism 5 for treatment, so that the waste gas is fully in contact with the activated carbon, and effectively removes the residual pollutants and odors in the waste gas. The activated carbon needs to be replaced regularly to ensure the waste gas treatment effect.

The sponge head 1096 performs spiral motion in the pipeline, scrapes from the end of the nozzle 1056 to the inside of the desulfurization tower 101, and cleans the debris onto the sieve plate 1061. At this time, the second telescopic rod 1094 is retracted, and the clamping plates 1097 on both sides of the sponge head 1096 are squeezed close to each other under the action of the second spring 1099, and the desulfurizer absorbed by the sponge head 1096 is squeezed out, filtered through the sieve plate 1061 and then concentrated at the bottom of the desulfurization tower 101. Cleaning the inside of the pipeline is beneficial to protecting the pipeline, avoiding corrosion by dangerous gases, and extending the service life of the pipeline.
