Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial waste gas treatment technology, and more specifically, to a cyclone dust removal device for an oil removal furnace flue gas spray tower. Background Technology
[0002] In the industrial production field, oil removal furnaces are a common type of equipment that generate a large amount of flue gas during operation. This flue gas contains not only particulate matter but also fine pollutants such as oil mist.
[0003] A search revealed that patent publication number CN210645837U discloses a spray tower for flue gas desulfurization, comprising a reaction tower, a flue gas conveying pipeline, a solution circulation system, a smoke disturbance structure, and an exhaust pipeline. The smoke disturbance structure separates the reaction tower into a spray chamber and a solution chamber. The spray tower, provided by the device, allows flue gas to flow relatively evenly within the reaction tower via a pressure-limiting valve. The smoke disturbance structure can simultaneously absorb flue gas and spray into its interior for reaction. Because the reaction chamber of the smoke disturbance structure is a constricted cylindrical shape, it allows for sufficient reaction between flue gas and spray. Furthermore, the solution circulation system in the device can spray the solution multiple times, increasing the solution utilization efficiency. During the development of this utility model, the inventors discovered the following problems with the existing technology:
[0004] When removing fine pollutants from flue gas, the removal effect on fine pollutants inside the flue gas is not good, making it difficult to meet increasingly stringent environmental emission standards. As a result, some pollutants are still discharged into the atmosphere, posing a potential threat to the environment. In terms of processing efficiency, the equipment does not have sufficient contact between the flue gas and the purification medium, resulting in a slow flue gas processing speed, which affects the overall production process and reduces the service life and reliability of the equipment.
[0005] Therefore, a cyclone dust removal device for an oil removal furnace flue gas spray tower is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cyclone dust removal device for an oil removal furnace flue gas spray tower to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a cyclone dust removal device for a flue gas scrubbing tower of an oil-removing furnace, comprising an oil-removing furnace housing, a housing cover placed stably on the top of the oil-removing furnace housing, the housing cover being tightly fitted to the oil-removing furnace housing, a support frame being stably installed on the outside of the oil-removing furnace housing, a connecting plate being fixedly installed on one side of the support frame by welding, a scrubbing tower body being reasonably arranged on the upper side of the connecting plate, the scrubbing tower body being located on the right side of the oil-removing furnace housing, the two being connected by the connecting plate to form a waste gas treatment passage, a waste gas pipe being connected to the top of the housing cover, the waste gas discharged from the oil-removing furnace housing entering the scrubbing tower body through this pipe, a water storage tank being configured on one side of the scrubbing tower body, a water supply pipe being connected to the top of the water storage tank for supplying water to the scrubbing tower body, a water spray ring being placed inside the scrubbing tower body through a connecting block, and spray nozzles being evenly arranged at the bottom of the water spray ring.

[0009] Preferably, the inner ring of the support frame is tightly fitted to the outer surface of the oil removal furnace housing, and the bottom of the support frame is firmly fixed with support legs.
[0010] Preferably, a gas pump is detachably installed on the outside of the exhaust pipe. The end of the exhaust pipe away from the oil removal furnace box is connected to the left side of the spray tower body. The exhaust pipe passes through the left side of the spray tower body and extends deep into the interior of the exhaust pipe. On the section of the exhaust pipe that extends into the interior of the spray tower body, multiple exhaust ports are evenly distributed at the bottom of the exhaust pipe.
[0011] Preferably, the water spray ring is located directly above the exhaust pipe, so that when the exhaust gas is discharged from the exhaust pipe, the water spray ring can spray water mist evenly downwards from directly above.
[0012] Preferably, a water pump is conveniently and detachably installed on the upper side of the water supply pipe, which runs through the right side of the spray tower and extends continuously into the interior of the spray tower.
[0013] Preferably, the bottom and top of the spray tower are designed with openings. The bottom of the spray tower has a slag discharge port, while the top of the spray tower has a corresponding exhaust port. The sizes of the slag discharge port and the exhaust port are matched.

The inner wall of the filter screen is also firmly fixed with lifting rings, which are used to lift or lower the filter screen.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] Compared with existing technologies, this cyclone dust removal device for an oil-removing furnace flue gas scrubbing tower has multiple exhaust ports installed inside the scrubbing tower via an exhaust pipe. Combined with a water spray ring that evenly sprays water mist from above, the exhaust gas and water mist come into full contact, significantly increasing the contact area and contact time. This effectively improves the removal efficiency of particulate matter and harmful gases from the flue gas. Compared with traditional equipment, the flue gas treatment speed is faster, enabling more efficient completion of purification tasks and meeting the requirements of industrial production for flue gas treatment efficiency.
[0017] Compared with existing technologies, this cyclone dust removal device for an oil removal furnace flue gas spray tower evenly disperses the exhaust gas through the exhaust outlet and evenly sprays water mist in all directions through the spray ring, forming a good purification environment. It has a stronger ability to capture and remove fine pollutants such as oil mist in the flue gas, ensuring that the purified flue gas meets strict environmental emission standards and reducing environmental pollution.
