Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a cyclone type sand removing device, specifically relates to an industrial tail gas combustion after circulating waterway cyclone type sand removing device, belongs to water treatment equipment technical field. BACKGROUND
[0002] The industrial tail gas produced in photovoltaic and semiconductor production is usually removed by burning, and the tail gas is burned in the reaction cavity of the reaction kettle, and the reaction cavity is cooled by circulating spray water. Since there are dust or particulate matters in the tail gas, the dust or particulate matters will fall into the water tank after burning, and will enter the spray pipeline with the water pump, which will cause wear and tear of the pipeline and blockage of the nozzle, thereby affecting the cooling effect of the reaction cavity, reducing the safety of the reaction cavity and shortening the service life.
[0003] It is considered to connect the cyclone type sand removing device with the circulating waterway to reduce the dust or particulate matters in the water. However, the existing cyclone type sand removing device has a complex structure and a large size, which is not suitable for this application scenario. UTILITY MODEL CONTENT
[0004] The utility model provides an industrial tail gas combustion after circulating waterway cyclone type sand removing device, which aims to overcome the above-mentioned deficiencies in the prior art and reduce the dust or particulate matters in the circulating water.
[0005] The technical solution of the utility model is as follows: an industrial tail gas combustion after circulating waterway cyclone type sand removing device, which comprises a reaction kettle, a water tank, a circulating pipeline, a circulating pump, a main nozzle, a branch pipe, a cyclone type sand removing device body and an atomizing nozzle. The water tank in the reaction kettle is connected with one end of the circulating pipeline with the circulating pump, the other end of the circulating pipeline is connected with the main nozzle in the reaction kettle, one end of the branch pipe connected with the circulating pipeline between the circulating pump and the main nozzle, the other end of the branch pipe is connected with the atomizing nozzle in the reaction kettle, the branch pipe is provided with the cyclone type sand removing device body, and the diameter of the conical cylinder of the cyclone type sand removing device body is less than or equal to 80 mm. The cyclone type sand removing device body is installed on the branch pipe of the circulating waterway. Even if only 10% of the circulating water in the branch pipeline, the circulating ratio can effectively reduce the particulate matters in the circulating water, and the possibility of blockage of the circulating water nozzle is reduced.
[0006] Preferably, the cyclone sand removal device includes a conical cylinder, a circular sealing cover, a water inlet, and a sand discharge port. The circular sealing cover is installed on the top of the conical cylinder, with a water outlet at its center. The sand discharge port is located at the bottom of the conical cylinder. The water inlet is located on the side of the conical cylinder, with its inner end eccentrically facing the tangential direction of the inner wall of the conical cylinder. The water outlet and the water inlet are connected to a branch pipe. When water flows tangentially into the conical cylinder through the water inlet under a certain pressure, it forms a strong vortex. Due to the density difference between sand particles and water, under the combined action of centrifugal force, centripetal buoyancy, and fluid drag, substances of different densities experience different forces. This causes the less dense water to rise and be discharged through the water outlet in the circular sealing cover, while the denser sand particles are discharged through the sand discharge port at the bottom of the conical cylinder, thus achieving the separation of sand particles.
[0007] The advantages of this utility model are: simple and reasonable structural design, equipped with a circulating water branch pipe with a small cyclone sand removal device, which can effectively reduce dust or particulate matter in the circulating water circuit, easy to install, can meet the needs of use, reduce wear on pipes and clogging of nozzles, improve the cooling effect of the reaction chamber, ensure the safety of the reaction chamber, and extend the service life.

Detailed Implementation
[0011] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.
[0012] like Figure 1 , 2As shown, an industrial exhaust gas combustion circulating water cyclone sand removal device includes a reactor 1, a water tank 2, a circulation pipeline 3, a circulation pump 4, a main nozzle 5, a branch pipe 6, a cyclone sand removal device body 7, and an atomizing nozzle 8. The water tank 2 in the reactor 1 is connected to one end of the circulation pipeline 3 with the circulation pump 4, and the other end of the circulation pipeline 3 is connected to the main nozzle 5 in the reactor 1. The circulation pipeline 3 between the circulation pump 4 and the main nozzle 5 is connected to one end of the branch pipe 6, and the other end of the branch pipe 6 is connected to the atomizing nozzle 8 in the reactor 1. The cyclone sand removal device body 7 is mounted on the branch pipe 6.
[0013] The main body 7 of the cyclone sand removal device includes a conical cylinder 71, a circular sealing cover 72, a water inlet port 73, and a sand discharge port 74. The diameter of the conical cylinder 71 is ≤80mm. The circular sealing cover 72 is installed on the top of the conical cylinder 71. The center of the circular sealing cover 72 is provided with a water outlet 721. The bottom end of the conical cylinder 71 is provided with a sand discharge port 74. The water inlet port 73 is located on the side of the conical cylinder 71. The inner end of the water inlet port 73 is eccentrically oriented towards the tangent direction of the inner wall of the conical cylinder 71. The water outlet 721 and the water inlet port 73 are connected to a branch pipe 6.
[0014] Based on the above structure, during operation, utilizing the working principles of centrifugal sedimentation and density difference, when water flows tangentially into the conical cylinder 71 through the inlet port 73 under a certain pressure, a strong vortex is formed. Due to the density difference between sand particles and water, under the combined action of centrifugal force, centripetal buoyancy, and fluid drag, substances of different densities will experience different forces, causing the less dense clear water to rise and be discharged through the outlet 721 inside the circular sealed cover 72, while the denser sand particles are discharged through the sand discharge port 74 at the bottom of the conical cylinder 1, thereby achieving the separation of sand particles. Because the water in the branch pipe 6 does not contain sand, it can be supplied to the atomizing nozzle 8.
[0015] Specifically, when water flows into the conical cylinder 71 through the inlet port 73, since the inlet port 73 is located at an eccentric position in the conical cylinder 71, the water first rotates along the tangential direction of the periphery of the conical cylinder 71 after entering the conical cylinder 71, forming a downward circumferential fluid. The water flows downward in the conical cylinder 71 in a rotating manner until it reaches a specific part of the conical cylinder 71. Then it rotates upward along the axis of the conical cylinder 71 and is discharged through the outlet 721 in the circular sealing cover 72. Meanwhile, solid particles in the water flow fall along the wall of the conical cylinder 71 under the action of the inertial centrifugal force of the fluid and its own gravity, and are discharged through the sand discharge port 74 at the bottom of the conical cylinder 7. The conical cylinder 71 has a diameter of ≤80mm, which allows for easy installation while meeting functional requirements. The cyclone sand removal device body 7 is installed on the branch pipe of the circulating water circuit. In actual operation, since the overall circulation rate is about 50-60 times / hour, even if the branch pipe has only 10% circulating water, the circulation rate of the cyclone sand removal device body 7 can reach 5-6 times / hour, which can effectively reduce particulate matter in the circulating water and reduce the possibility of the circulating water nozzles being blocked.
[0016] Without the branch pipe 6 and the cyclone sand removal device body 7, dust or particles are continuously generated in the water and constantly carried away by the drainage. This process generally reaches a balance, for example, requiring an average of 100 cycles by the circulating pump 4 to remove them. However, this continuous wear and tear on the reaction chamber pipes and blockage of the nozzles (main nozzle 5) causes the dust or particles to accumulate. Adding the branch pipe 6 and the cyclone sand removal device body 7 shortens this to an average of 10 cycles, thus purifying the water tank 2 and reducing wear and blockage.
[0017] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
