Description

Technical Field

[0001] The invention relates to the technical field of desulfurization towers, and in particular to a disturbance guide cone device for a desulfurization tower. Background Art

[0002] As we all know, a desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. Desulfurization towers are mostly spray towers. The waste gas flows from bottom to top in the tower body. The gas streamlines are straight and the gas flow is stable. The effective contact area with the absorption solvent in the tower body is small, resulting in low absorption efficiency. For this reason, a turbulent structure is often installed to disturb the airflow to improve the removal effect of the absorbent in the tower body on sulfides in the waste gas.

[0003] For example, Chinese utility model patent CN212348256U discloses a high-efficiency chemical absorption tower with a spoiler structure, including a tower body and a spray plate, an air outlet is installed on the top of the tower body, an air inlet is installed on the lower part of one side of the tower body, and a spoiler mechanism is installed inside the tower body just below the spray plate; the spoiler mechanism changes the flow state of the airflow by adjusting the inclination angle of the flow-around plate, so that the flow state of the airflow is turbulent and fully contacts with the solvent; the flow state of the airflow is changed, and the flow state of the airflow becomes more chaotic, thereby improving the absorption efficiency.

[0004] However, when the inventors implemented this device, they found the following defects: the intake flow rate and pressure of the exhaust gas into the tower body are unstable, the spraying amount of the absorption solvent in the tower body is basically constant, when the exhaust gas flow rate and pressure increase suddenly, the residence time of the exhaust gas in the tower body is shortened, the exhaust gas and the absorption solvent are difficult to fully contact, and the absorption and separation of sulfides in the exhaust gas are not complete, affecting the desulfurization effect of the exhaust gas; and the change of the exhaust gas flow rate will also have an impact on downstream equipment.

[0043] Example 2

[0044] The desulfurization tower disturbance guide cone device provided in Example 1 is further optimized, specifically, Figure 7 and Fig. 9 As shown, it also includes an absorption solvent spraying assembly, which includes a main pipe 15 fixedly installed on the outer wall of the outer cylinder 1, multiple branch pipes 16 and a diffuser installed at the end of the branch pipe 16, one end of the branch pipe 16 is connected to the inside of the main pipe 15, and the other end of the branch pipe 16 extends into the annular guide channel. The diffuser includes a nozzle part 17, a support frame 18 integrally connected to the nozzle part 17, a shaft 19 rotatably installed on the support frame 18, a cone head 20 fixedly installed on the shaft 19 near one end of the nozzle part 17, and a throw-off disk 21 fixedly installed on the other end of the shaft 19, a radial impeller 22 is fixedly installed on the throw-off disk 21, and the tip of the cone head 20 faces the outlet port on the nozzle part 17.

[0045] For details, please refer to Figure 4 , the central axis of the diffuser coincides with a radial line of the annular guide channel; further, the diffuser is arranged along the radial direction of the annular guide channel, and multiple diffusers are arranged circumferentially around the annular guide channel; the above arrangement can make the airflow act on the radial impeller 22 along the radial direction of the radial impeller 22, so as to improve the rotational driving effect of the airflow on the radial impeller 22, and maximize the use of the airflow to increase the rotation speed of the radial impeller 22, thereby increasing the range of droplets being thrown, and further improving the contact uniformity between the absorption solvent and the exhaust gas.

[0046] For details, please refer to Figure 7 A spiral guide groove 23 is provided on the cone head 20.

[0047] For details, please refer to Figure 7 or Fig. 9The middle part of the ejection disk 21 is convex toward one side near the nozzle portion 17, and the outer circumference of the ejection disk 21 is provided with tooth grooves 24 that are evenly distributed in the circumferential direction.

[0048] The desulfurization tower disturbance guide cone device provided in this embodiment connects the main pipe 15 with the external pressurized absorption solvent supply equipment, and the pressurized absorption solvent is sprayed into the annular guide channel through the main pipe 15, the branch pipe 16 and the nozzle part 17. The liquid column sprayed from the nozzle part 17 is initially dispersed after contacting the cone head 20. The cone head 20 and the spiral guide groove 23 can cause the liquid column to form a conical vortex liquid surface. The conical vortex liquid surface acts on the ejection disk 21 to form scattered droplets. The airflow acts on the radial impeller 22 during its movement in the annular guide channel and drives it to rotate. The radial impeller 22 drives the ejection disk 21 to rotate. Under the action of centrifugal force, the droplets are evenly dispersed and ejected, so that the absorption solvent entering the annular guide channel is fully in contact with the exhaust gas, so as to improve the absorption effect of the absorption solvent on the sulfide in the exhaust gas; and the protrusions and tooth grooves 24 on the ejection disk 21 have a positive effect on the dispersion area and dispersibility of the droplets, so as to improve the dispersibility and action area of ​​the absorbent droplets.

[0049] The use process of the desulfurization tower disturbance guide cone device provided by the present invention is as follows: the desulfurization tower disturbance guide cone device is installed in the desulfurization tower, and the exhaust gas entering the desulfurization tower is dispersed in annular shape and enters the annular guide channel under the action of the disturbance cone. Under the action of the disturbance blade 4, the airflow forms a vortex, which has a slowing effect on the flow rate of the exhaust gas entering the desulfurization tower, and at the same time prolongs the residence time of the exhaust gas in the desulfurization tower. The pressurized absorption solvent is sprayed into the annular guide channel through the main pipe 15 and the branch pipe 16. Under the action of the diffuser, the absorption solvent forms evenly dispersed droplets, which increases the contact frequency between the exhaust gas and the absorption solvent in the desulfurization tower. The vortex airflow is in uniform contact with the absorption solvent, and then is guided for the second time by the guide impeller 25, which promotes further contact between the absorption solvent and the exhaust gas, so that the absorption solvent can effectively separate and remove the sulfide in the exhaust gas.
