Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of spray tower equipment, and particularly relates to a waste gas spray tower equipment for waste gas treatment. BACKGROUND

[0002] As a key environmental protection equipment for implementing spray method to govern air pollution, purify industrial waste gas or recycle raw materials, the waste gas spray tower plays an important role in the field of air pollution prevention and control, and is also called water washing tower, scrubbing tower or purification tower. The waste gas spray tower can effectively remove dust particles, acid gases (such as SO2 and HCl), alkaline gases (such as NH3) and part of soluble organic pollutants in waste gas through liquid phase mass transfer, and is an important component equipment for responding to air pollution and realizing pollutant discharge up to standard.

[0003] When the waste gas spray tower is used to treat waste gas containing oil stains, the oil stains are captured by the spray water and brought into the circulating water system. When the subsequent filtering element (such as filter bag, filter core or filter plate) is used to filter the part of oil-containing wastewater for reuse, the oil stains mixed in the water will be blocked on the upper surface of the filtering element. This blockage will cause two direct consequences: 1. The filtering channel is closed, the water flow cannot pass smoothly, the filtering system fails, and the output of clean water is sharply reduced or interrupted; 2. The waste gas spray tower system cannot obtain sufficient circulating water supply, and in order to maintain the spray operation, fresh water must be introduced from the outside, which not only increases the consumption of water resources, but also increases the operating cost. At the same time, the filtering element blocked by oil stains also needs to be manually cleaned by the staff to restore its function. This cleaning process is often time-consuming and labor-intensive, and the filtering system needs to be interrupted, which seriously affects the continuity and stability of the entire waste gas treatment system, and the maintenance efficiency is low, which greatly reduces the treatment efficiency and reliability when treating waste gas.

[0045] Specifically, the guide plate 77 with oil dispersing grooves 78 is used to cut and disperse the surface oil, thereby increasing the contact area with the cleaning agent; then the injection amount of the oil cleaning agent is intelligently adjusted according to the severity of clogging (the current value of the resistance plate 89) to realize precise use of the agent; finally, the dissolved and dispersed oil is gathered by the scraper 710 to temporarily restore the water passing capacity of the filter 61. All the operations are automatically completed inside the equipment without interrupting the waste gas treatment process.

[0046] The operation principle of the present application is described as follows:

[0047] In the present application, when the exhaust gas with oil stains needs to be sprayed, first, the pipeline discharging the exhaust gas is connected with the air inlet pipe 4, and then the exhaust gas is discharged into the tower body 1. After entering the tower body 1, the exhaust gas flows upward. At this time, the water pump 62 is started to send the water at the bottom of the tower body 1 to the connecting shell 51 through the connecting pipe 63, and the multiple first nozzles 52 are started to spray the water in the connecting shell 51 to the exhaust gas, thereby realizing the spraying of the exhaust gas, so that the oil stains and other substances in the exhaust gas are dissolved in the water. After that, the sprayed exhaust gas passes through the demisting plate 53. After the demisting plate 53 is used to dehydrate and demist the sprayed exhaust gas, the treated exhaust gas is discharged from the air outlet hole 3, thereby completing the spraying treatment of the exhaust gas. The water after the spraying of the exhaust gas falls on the filter element 61, and the oil stains and other substances in the water are filtered by the filter element 61. The filtered water flows to the bottom of the tower body 1, so that the water pump 62 can continue to provide water to the first nozzles 52, thereby continuously spraying the exhaust gas. However, the water discharged above the filter element 61 contains oil stains, which are easy to block above the filter element 61. At this time, the water cannot flow to the bottom of the tower body 1 through the filter element 61. At this time, the water at the bottom of the tower body 1 will continue to decrease. After the water at the bottom of the tower body 1 decreases to a certain extent, the floating plate 86 will float on the water surface at the bottom of the tower body 1. At this time, as the filter element 61 is blocked, the water level at the bottom of the tower body 1 will continue to decrease, and the floating plate 86 will move downward with the water level. Since the thrust caused by the buoyancy of the floating plate 86 is greater than the elastic force of the supporting spring 84, at this time, the floating plate 86 will overcome the elastic force of the supporting spring 84 to drive the baffle 85 to move downward. With the movement of the floating plate 86, the conductive plate 88 will move downward. At this time, as the conductive plate 88 moves downward, the resistance value of the resistance plate 89 will continue to change. The greater the distance that the conductive plate 88 moves downward, the smaller the resistance of the resistance plate 89, and the greater the current. At this time, it indicates that the distance of the water level decrease is higher. The current of the resistance plate 89 is timed from the beginning of the change. After a certain time, the current of the resistance plate 89 is proportional to the blocking condition of the filter element 61. At this time, the first electric telescopic rod 76 is controlled to start, and the guide plate 77 is driven to move downward, so that the bottom end side wall of the guide plate 77 is in contact with the surface of the filter element 61. Then, the first electric sliding rail 72 is controlled to start, and the corresponding two first sliding plates 73 are driven to move, so that the guide plate 77 rotates on the surface of the filter element 61. The oil stains on the surface of the filter element 61 are separated by the oil separation groove 78 to increase the contact area of the oil stains with the outside. Then, the second nozzle 75 is controlled to start, and the oil stain cleaning agent in the storage shell 74 is sprayed to the oil stains on the surface of the filter element 61. At this time, the power of the second nozzle 75 is related to the current size of the resistance plate 89, so that the second nozzle 75 sprays the corresponding amount of oil stain cleaning agent according to the blocking condition of the filter element 61. The second nozzle 75 is driven to rotate by the first sliding plate 73, so that the second nozzle 75 can cover the surface of the filter element 61 with oil stain cleaning agent. After the surface of the filter element 61 is completely covered with the corresponding oil stain cleaning agent, the second electric telescopic rod 79 is controlled to start,The scraper 710 is in contact with the surface of the filter element 61, and then the first sliding plate 73 drives the scraper 710 to continue to rotate, and the oil stains on the surface of the filter element 61 are scraped to a piece by the scraper 710, so that the oil stains do not continue to block the surface of the filter element 61, and it is convenient for the subsequent cleaning and collection of the oil stains by the workers. At this time, the water after spraying can quickly pass through the filter element 61 to the bottom of the tower body 1, so that the waste gas can be continuously sprayed. When the resistance value of the resistance plate 89 changes again, the oil stains can be cleaned according to the above steps. However, when the resistance value of the resistance plate 89 changes, the pressure sensor 811 detects the pressure when the floating plate 86 is in contact with the pressure sensor 811 within a certain period of time. At this time, it is indicated that the blockage of the filter element 61 is too serious, and the cleaning effect of the oil stains by the scraper 710 is not good. At this time, the workers can be reminded in time to manually clean or replace the filter element 61.

[0048] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical range disclosed in the present application according to the technical solution and the inventive concept of the present application, which should be covered within the protection scope of the present application.
