Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a desulfurization tower ejector. Background Art

[0002] A desulfurization tower is a tower device for desulfurizing industrial waste gas. The role of the ejector in the desulfurization tower is to mix the desulfurization liquid and the gas to be desulfurized, so as to achieve the purpose of desulfurizing the gas. The existing ejector often selects a spiral ejector. However, after the spiral ejector is used in the desulfurization tower for a long time, the desulfurization liquid and the waste gas will solidify and block the nozzle of the spiral ejector after mixing, and it is time-consuming and laborious to clean after blocking. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a desulfurization tower ejector, which is used to solve the problems that the existing desulfurization tower ejector is easy to block and not easy to clean.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A desulfurization tower ejector includes a connecting pipe, a pull rod and a first guide plate. The top of the connecting pipe is connected to the desulfurization tower, and the bottom is connected to the inclined surface of the first guide plate through a plurality of pull rods. The first guide plate is a hollow frustum structure, and a flow dividing cylinder is arranged at the top of the first guide plate. The diameter of the flow dividing cylinder is smaller than that of the connecting pipe.

[0006] Further, the bottom of the first guide plate is connected to a second guide plate through a plurality of pull rods, and the second guide plate is in the shape of a bamboo hat.

[0007] Further, the diameter of the first guide plate is larger than that of the second guide plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: The utility model has a simple structure and low cost. Under the action of the first guide plate and the flow dividing cylinder at its top, one side of the liquid flowing into the connecting pipe flows out through the flow dividing cylinder, and the other part flows out under the action of the first guide plate, which is not easy to block, and the cleaning process is more convenient and simple than that of the spiral ejector after blocking; the second guide plate enables the liquid passing through the flow dividing cylinder to be dispersed twice, and finally forms a double-layer umbrella-shaped spraying effect, which can increase the contact surface between the liquid and the gas and greatly improve the desulfurization efficiency.

[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the attached drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0013] A desulfurization tower ejector includes a connecting pipe 1, a pull rod 5 and a first guide plate 2. The top end of the connecting pipe 1 is connected to the desulfurization tower, and the bottom end is connected to the inclined surface of the first guide plate 2 through a plurality of pull rods 5. The first guide plate 2 is a hollow frustum structure. A flow dividing cylinder 3 is provided at the top of the first guide plate 2, and the diameter of the flow dividing cylinder 3 is smaller than the diameter of the connecting pipe 1. The structure of the present utility model is simple and the cost is low. Under the action of the first guide plate 2 and the flow dividing cylinder 3 at its top, one side of the liquid flowing into the connecting pipe 1 flows out through the flow dividing cylinder 3, and the other part flows out under the action of the first guide plate 2, which is not easy to be blocked, and the cleaning process is convenient and simple compared with a spiral ejector after being blocked.

[0014] The bottom of the first guide plate 2 is connected to a second guide plate 4 through a plurality of pull rods 5. The second guide plate 4 is in the shape of a bamboo hat. The second guide plate 4 enables the liquid passing through the flow dividing cylinder 3 to be dispersed secondly, and finally forms a double-layer umbrella-shaped spraying effect. Such a design can increase the contact surface between the liquid and the gas, and greatly improve the desulfurization efficiency.

[0015] The diameter of the first guide plate 2 is larger than the diameter of the second guide plate 4. When the first guide plate 2 and the second guide plate 4 are used simultaneously, the liquid can be sprayed in a staggered layered manner, increasing the spraying area.

[0016] During use, the connecting pipe 1 is connected to the desulfurization tower. The liquid is sprayed out of the connecting pipe 1 under the action of pressure. Part of the liquid is sprayed onto the first flow dividing plate to disperse the liquid, and the other part of the liquid is sprayed onto the second flow dividing plate through the flow dividing cylinder 3 to disperse the liquid secondly, and finally forms a double-layer umbrella-shaped spraying effect. The present utility model is not only not easy to be blocked, but also can increase the liquid circulation amount, fully contact with the gas, and greatly improve the desulfurization effect.

[0017] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
