Technical Field

[0001] The invention relates to the technical field of venturi jet graphite quench coolers, in particular to a venturi jet graphite quench cooler cooled by a circulating water jacket and a cooling method. Background Art

[0002] The principle of the Venturi effect is that when the wind blows over an obstacle, the air pressure near the port above the leeward side of the obstacle is relatively low, which produces an adsorption effect and causes the air to flow. The principle of the Venturi tube is actually very simple. It changes the airflow from coarse to fine to speed up the gas flow rate, so that the gas forms a vacuum area on the rear side of the Venturi tube outlet. When this vacuum area is close to the workpiece, it will have a certain adsorption effect on the workpiece. This device is a Venturi jet graphite quencher, which is used for the rapid cooling of high-temperature acid-containing tail gas;

[0003] When the Venturi jet graphite quench cooler is in use, the effect is poor when the heat of the exhaust gas is adsorbed by the inner impregnated graphite layer alone;

[0004] Therefore, a circulating water jacket-cooled venturi jet graphite quencher and a cooling method are needed to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a circulating water jacket cooled venturi jet graphite quencher and a cooling method to solve the problem of poor cooling effect of the venturi jet graphite quencher in the background art.

[0014] Preferably, two groups of transparent plates are installed inside the observation window, and the two groups of transparent plates are distributed in parallel.

[0015] A cooling method for a circulating water jacket-cooled venturi jet graphite quencher comprises the following steps:

[0016] P1: The exhaust gas enters through the top opening of the compression inlet pipe, moves along the compression inlet pipe, throat pipe, diffuser pipe, and is sent out through the bottom opening of the diffuser pipe;

[0017] P2: When the tail gas moves, the heat can be transferred to the outside along the graphite layer inside the compression inlet pipe, throat pipe and diffusion pipe. A circulation pipeline is arranged inside the jacket body. With the assistance of the circulation inlet pipe and the circulation outlet pipe, a low-temperature liquid is introduced for circulation.

[0018] P3: Low-temperature liquid flows along the outer wall of the compression inlet pipe, throat pipe, and diffusion pipe to assist in taking away the heat of the outer wall and perform auxiliary cooling treatment from the outside. Inside, liquid is introduced through the water pipe, and the liquid enters the spray plate along the extension pipe and spray pipe, and is sprayed out through multiple groups of nozzles on the outside of the spray plate;

[0019] P4: When the exhaust gas moves inside the compression inlet pipe and throat, it drives the fan blades to drive the spray disc to rotate, rotate the spray position of the nozzle, and spray evenly. When the rotating fan blades come into contact with the spraying liquid, they assist in shearing and stirring the liquid and exhaust gas to mix. By compressing the diameter of the inlet pipe and throat section, the flow rate of the high-temperature acid-containing flue gas is increased, driving the spray liquid in the middle and top to spray and mix quickly, driving the high-temperature flue gas to achieve rapid cooling.

[0020] Compared with the prior art, the invention has the following beneficial effects: by providing a circulation pipeline, the circulation pipeline is located on the inner side of the jacket body, and is spirally welded on the outer side wall of the compression inlet pipe, the throat pipe, and the diffuser for use. When in use, a low-temperature medium is introduced through the circulation inlet pipe at the bottom end of the right side, and after flowing, it is discharged through the circulation outlet pipe at the top position of the right side, thereby circulating. The circulating low-temperature medium can assist in driving the heat transferred to the outside by the compression inlet pipe, the throat pipe, and the diffuser, and assist in cooling treatment, thereby enhancing the auxiliary cooling function of the Venturi jet graphite quencher when in use;

[0021] By providing the nozzle and the fan blade, as the tail gas flows in the compressed inlet pipe and the throat pipe, the fan blade outside the spray plate can be assisted to drive the spray plate to rotate, so that the spray position of the nozzle can be rotated to evenly spray. When the rotating fan blade contacts the spraying liquid, it can also assist in shearing and stirring the liquid and the tail gas, thereby realizing the rotary spraying function of the Venturi jet graphite quencher;

[0022] An observation window and a transparent plate are provided. The observation window is located at the tail end of the diffusion tube and a transparent plate is installed inside for sealing. When in use, the transparent plate inside the observation window can be used to assist in observing the situation inside the diffusion tube, thereby realizing the auxiliary observation function when using the Venturi jet graphite quencher.

[0032] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when in use, the cryogenic liquid is fed into the circulation pipeline 6 through the circulation inlet pipe 7 to flow, and then discharged through the circulation outlet pipe 8. When the cryogenic liquid moves in the circulation pipeline 6, the cryogenic liquid contacts and compresses the outer wall of the inlet pipe 1, the throat pipe 2 and the diffusion pipe 3, which can assist in taking away the heat transferred from the inside to the outside, and assist in the cooling process;

[0037] A cooling method for a circulating water jacket-cooled venturi jet graphite quencher comprises the following steps:

[0038] P1: exhaust gas enters through the top opening of compression inlet pipe 1, moves along compression inlet pipe 1, throat pipe 2, diffuser pipe 3, and is sent out through the bottom opening of diffuser pipe 3;

[0039] P2: When the tail gas moves, the heat can be transferred to the outside along the graphite layer inside the compression inlet pipe 1, the throat pipe 2, and the diffusion pipe 3. A circulation pipeline 6 is arranged inside the jacket body 4. With the assistance of the circulation inlet pipe 7 and the circulation outlet pipe 8, a low-temperature liquid is introduced for circulation.

[0040] P3: Low-temperature liquid flows along the outer wall of the compression inlet pipe 1, throat pipe 2, and diffuser pipe 3, assisting in taking away the heat of the outer wall, and performing auxiliary cooling treatment from the outside. Inside, liquid is introduced through the water pipe 11, and the liquid enters the spray plate 16 along the extension pipe 12 and the spray pipe 13, and is sprayed out through the multiple groups of nozzles 17 on the outside of the spray plate 16;

[0041] P4: When the exhaust gas moves inside the compressed inlet pipe 1 and the throat pipe 2, the fan blades 18 drive the spray plate 16 to rotate, rotate the spraying position of the nozzle 17, and evenly spray. When the rotating fan blades 18 come into contact with the spraying liquid, they assist in shearing and stirring the liquid and the exhaust gas to mix. By compressing the diameter change of the inlet pipe 1 and the throat pipe 2, the flow rate of the high-temperature acid-containing flue gas is increased, driving the spray liquid in the middle and top to spray and mix quickly, driving the high-temperature flue gas to achieve rapid cooling.

[0042] Working principle: When in use, the compression inlet pipe 1, the throat 2 and the diffuser 3 are combined into a Venturi tube structure. At the same time, the inner walls of the compression inlet pipe 1, the throat 2 and the diffuser 3 are lined with impregnated graphite. The tail gas enters through the top opening of the compression inlet pipe 1, moves along the compression inlet pipe 1, the throat 2 and the diffuser 3, and is sent out through the bottom opening of the diffuser 3. When the tail gas moves, the heat can be transferred to the outside along the graphite layer inside the compression inlet pipe 1, the throat 2 and the diffuser 3. A circulation pipeline 6 is arranged inside the jacket body 4. With the assistance of the circulation inlet pipe 7 and the circulation outlet pipe 8, a low-temperature liquid is introduced for circulation. When the low-temperature liquid flows along the outer wall of the compression inlet pipe 1, the throat 2 and the diffuser 3, it can assist in taking away the outside. The heat of the wall is assisted by cooling treatment from the outside, and liquid is introduced into the inside through the water pipe 11. The liquid enters the spray plate 16 along the extension pipe 12 and the spray pipe 13, and is sprayed out through the multiple groups of nozzles 17 on the outside of the spray plate 16. When the exhaust gas moves inside the compressed entry pipe 1 and the throat pipe 2, it can drive the fan blades 18 to drive the spray plate 16 to rotate, so that the spraying position of the nozzle 17 can be rotated to perform the spraying operation evenly. When the rotating fan blades 18 come into contact with the sprayed liquid, they can also assist in shearing and stirring the liquid and the exhaust gas. The flow rate of the high-temperature acid-containing flue gas is increased by compressing the diameter change of the entry pipe 1 and the throat pipe 2, driving the spray liquid in the middle and top to spray and mix quickly, and driving the high-temperature flue gas to achieve rapid cooling.
