Description

Technical Field

[0001] The utility model relates to the technical field of equipment used in coke oven gas purification process, in particular to a desulfurization liquid dosing device used in coke oven gas purification process. Background Art

[0002] In the coke oven gas purification process, one of the steps is to pass the coke oven gas into a desulfurization tower to desulfurize the coke oven gas. The desulfurization tower will continuously spray desulfurization liquid to desulfurize the coke oven gas. The desulfurization liquid is supplied to the desulfurization tower through special desulfurization liquid dosing equipment.

[0003] When the existing desulfurization liquid dosing equipment is used, the prepared desulfurization liquid is generally directly added into the mixing tank of the dosing equipment. A drug delivery pump is fixedly installed at the bottom of the mixing tank to pump the desulfurization liquid into the desulfurization tower.

[0004] It is not difficult to see that the existing dosing equipment does not have the function of preparing the desulfurization liquid when in use, and if the prepared desulfurization liquid is stored in the mixing tank for a long time, precipitation is likely to occur, thus affecting the desulfurization effect of the coke oven gas. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a desulfurization liquid dosing device for a coke oven gas purification process, which, when in use, has the function of configuring the desulfurization liquid and can effectively prevent the precipitation of the desulfurization liquid after being stored for a long time.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] A desulfurization liquid dosing device for a coke oven gas purification process comprises a tank body and a tank cover of a mixing tank, a stirring mechanism, a water injection port, a reagent adding structure and a feed pump; the tank cover is arranged on the tank body, and the inner side of the tank body is provided with a stirring mechanism and a reagent adding structure respectively arranged on the tank cover, a water injection port is arranged on one side of the top of the tank cover, a feed pump is fixedly installed on one side of the bottom of the tank body, and a discharge pipe is connected to the discharge port of the feed pump;

[0008] The drug adding structure includes a filling hopper, a conveying pipe, a feeding pipe and a distribution pipe; the bottom end of the conveying pipe is closed, the top is connected and fixed to the tank cover, and the top end extends to the outside of the tank cover, the top end is connected to the filling hopper, and the top end is provided with a material valve located on the upper side of the tank cover. The distribution pipe is a circular tube structure, and the horizontal side is connected to the conveying pipe through the feeding pipe, and a plurality of discharge holes evenly distributed along the circumferential direction are reserved on the lower side of the distribution pipe.

[0009] As an improvement, the stirring mechanism includes a motor, a rotating shaft and a stirring blade; after the top of the rotating shaft is rotatably connected to the tank cover, the top extends to the upper side of the tank cover and is connected to the motor drive installed and fixed on the top of the tank cover. The stirring blade is an X-shaped rod structure with a through hole reserved in the middle, and is fixed on the rotating shaft through the through hole. On the one hand, it can make the liquid agent and water mix more quickly and fully, and quickly prepare the desulfurization liquid; on the other hand, it can prevent precipitation in the desulfurization liquid.

[0010] As an improvement, a plurality of stirring blades are evenly arranged along the axial direction of the rotating shaft, and a pair of material distribution pipes are correspondingly arranged between two adjacent stirring blades, so that the liquid medicine can be added to the medicine mixing tank more evenly.

[0011] As an improvement, the tank body is a cylindrical structure, and a sewage outlet with a valve is provided at the bottom. When cleaning the medicine mixing tank, the sewage after cleaning can be conveniently discharged through the sewage outlet.

[0012] It is worth mentioning that the motor in this technical solution is an existing device well known to those skilled in the art, and its use and control methods are all existing technologies.

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. When the present invention is in use, the water and the desulfurization liquid agent are added into the mixing tank together through the design of the stirring mechanism. The automatic dispensing function of the present invention can be realized through the operation of the stirring mechanism. Moreover, if the prepared desulfurization liquid is stored for a long time, the continuous operation of the stirring mechanism will not easily cause the desulfurization liquid to precipitate.

[0015] 2. When the new type is in use, multiple distribution pipes are provided, and they are respectively arranged between two adjacent stirring blades, so that the liquid reagent can be supplied to the mixing tank more evenly, accelerating the uniform preparation of the desulfurization liquid.
