Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide treatment technology, and in particular relates to a carbon dioxide treatment device for coal-fired power plants. Background Technology

[0002] The process of burning coal to generate electricity in coal-fired power plants will inevitably produce many gases that are harmful to the environment. For example, carbon dioxide is a greenhouse gas. If it is released directly without treatment, it will cause considerable harm to the atmosphere.

[0003] In the process of developing this utility model, the inventors discovered at least the following problems with the technology: Currently, carbonates are often obtained by mixing ionic solutions of hydroxides with carbon dioxide waste gas to reduce the harm of carbon dioxide. However, most treatment devices used for the reaction of carbon dioxide waste gas with hydroxide ionic solutions discharge carbon dioxide waste gas all at once without further processing, and the solution is also not processed separately, leading to a decrease in reaction efficiency.

[0004] Therefore, we propose a carbon dioxide treatment device for coal-fired power plants to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a carbon dioxide treatment device for coal-fired power plants. The carbon dioxide waste gas is dispersed and discharged into the treatment box through the dispersion pipes on both sides of the bottom of the central pipe. This allows the dispersed carbon dioxide waste gas to come into close contact with the hydroxide ion solution sprayed by multiple nozzles above, thereby greatly improving the reaction efficiency and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The end of the input pipe away from the pump passes through the top wall of the storage tank and extends into the bottom of the inner cavity of the storage tank. The end of the output pipe away from the pump passes through the treatment box and connects to the collection tank located inside the treatment box, thereby inputting an ionic solution of hydroxide into the collection tank. Supports are symmetrically welded at both ends of the collection tank, and both supports are welded to the top wall of the inner cavity of the treatment box to ensure the stability of the collection tank.

[0008] As a preferred embodiment, a drain pipe is fixedly connected to the bottom of one side wall of the treatment box, and a valve is installed on the drain pipe; the opening and closing of the drain pipe is controlled by operating the valve, so that the solution after reaction can be conveniently discharged.

[0009] As a preferred embodiment, the other end of the through pipe is located outside the treatment box, and the through pipe passes through the side wall of the treatment box and is fixedly welded to the treatment box; so as to ensure the stability of the structure of the through pipe.

[0010] As a preferred embodiment, the two groups of dispersion pipes on the through pipe are both located at the bottom of the outer wall of the through pipe, and both groups of dispersion pipes are communicated with the through pipe; so as to conveniently disperse the carbon dioxide waste gas through the two groups of dispersion pipes, and each group of dispersion pipes has a plurality of dispersion pipes and is distributed at equal intervals along a straight line.

[0011] As a preferred embodiment, an external pipeline is connected to one side of the top wall of the liquid storage tank; and the external pipeline is connected to an external facility for storing ionic solution of hydroxide, so as to conveniently send the ionic solution of hydroxide from the external facility into the inner cavity of the liquid storage tank through the external pipeline.

[0012] As a preferred embodiment, an exhaust pipeline is connected to the side wall of the treatment box which is opposite to the through pipe; so as to conveniently discharge the treated gas.

[0013] In summary, the technical effects and advantages of the present application are as follows:
