[0002] When preparing a new aqueous solution in the laboratory, it is necessary to test the reaction rate of the aqueous solution with the flue gas from the waste incineration power plant to determine the reaction rate of the aqueous solution. However, if the flue gas from the waste incineration power plant is generated by mixing various gases in a certain ratio, this will increase the cost of the test, and the concentrations of the flue gas will also be different from the actual flue gas from the waste incineration power plant. In addition, at the beginning of the reaction, the concentration of the exhaust gas is low, making it difficult for the exhaust gas to consume all the aqueous solution, and the unreacted aqueous solution will remain at the bottom of the reaction tank, affecting the accuracy of subsequent reaction tests.

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0018] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.
[0019] Reference Figures 1 to 3 The illustrated semi-dry reactor for purifying flue gas from a waste incineration power plant comprises a gasoline engine 1, a liquid storage tank 3, a reaction tube 4, an aqueous solution delivery device, and multiple nozzles 6. The gasoline engine 1 is connected to the liquid storage tank 3 via a pipe 1 and is used to deliver waste incineration power plant flue gas into the liquid storage tank 3. The gas produced by the gasoline engine 1 is waste incineration power plant flue gas, avoiding the need for a ratio-based method to produce waste incineration power plant flue gas, saving costs, and achieving a gas concentration comparable to waste incineration power plant flue gas. The reaction tube 4 is fixedly mounted on the top of the liquid storage tank 3 and communicates with the interior of the liquid storage tank 3. Multiple nozzles 6 are arranged in a vertical array within the reaction tube 4. The aqueous solution delivery device delivers aqueous solution to the multiple nozzles 6, causing the aqueous solution to be sprayed along the nozzles 6. The sprayed aqueous solution reacts with the waste incineration power plant flue gas in the reaction tube 4, while some unreacted aqueous solution reacts with the waste incineration power plant flue gas in the liquid storage tank 3.
[0020] Among them, a gas heating tank 2 is provided in the middle of the pipeline 1, and the gas heating tank 2 is used to heat the flue gas from the waste incineration power plant discharged by the gasoline engine 1 toward the liquid storage tank 3, so that the heated gas can simulate the flue gas from the waste incineration power plant in terms of temperature, avoiding the influence of temperature on the accuracy of the test.
[0021] The liquid medicine delivery device includes a liquid medicine tank 7 and a liquid medicine delivery pipe 5. A plurality of branch air pipes are provided on one end of the liquid medicine delivery pipe 5, and the plurality of branch air pipes are respectively connected to a plurality of nozzles 6. The other end of the liquid medicine delivery pipe 5 is connected to the liquid medicine tank 7. A pump body is provided on the liquid medicine tank 7. The pump body draws out the liquid medicine inside the liquid medicine tank 7 and transports it along the liquid medicine delivery pipe 5 so that it can be sprayed along the plurality of nozzles 6.
[0022] The interior of the liquid accumulating tank 3 is provided with a conical funnel 8 and a gate mechanism 9. The conical funnel 8 is fixedly mounted on the inner bottom of the liquid accumulating tank 3. The bottom of the conical funnel 8 is provided with a liquid outlet 8a. The gate mechanism 9 is used to control the opening and closing of the liquid outlet 8a. At the beginning of the reaction, the unreacted aqueous solution will fall onto the conical funnel 8, and then the gate mechanism 9 will be opened, and the aqueous solution will be discharged along the liquid outlet 8a, that is, the aqueous solution will enter between the conical funnel 8 and the bottom of the liquid accumulating tank 3, avoiding the subsequent waste incineration power plant flue gas. A liquid outlet pipe 3a is provided on the outer edge of the liquid accumulating tank 3. The liquid outlet pipe 3a is located below the conical funnel 8. When it is necessary to clean the aqueous solution between the conical funnel 8 and the bottom of the liquid accumulating tank 3, the valve connected to the liquid outlet pipe 3a will be opened to allow the aqueous solution to be discharged to the outside of the liquid accumulating tank 3.
[0023] The gate mechanism 9 includes a gate plate 9a, an electric push rod 9c, and two guide posts 9b. The gate plate 9a covers the bottom of the liquid outlet 8a. The two guide posts 9b are fixedly mounted at both ends of the gate plate 9a. Both guide posts 9b penetrate the outer wall of the liquid storage tank 3 and are slidably connected to the liquid storage tank 3. The electric push rod 9c is located outside the liquid storage tank 3, and the output end of the electric push rod 9c is fixedly connected to one end of one of the guide posts 9b. By controlling the electric push rod 9c to operate, the electric push rod 9c pulls the guide post 9b to move horizontally, which drives the gate plate 9a to cover and move, so that the gate plate 9a opens or closes the liquid outlet 8a. The guide posts 9b mainly guide the movement of the gate plate 9a. And because the gate plate 9a covers the liquid outlet 8a during the reaction, air leakage between the guide posts 9b and the liquid storage tank 3 is avoided.
[0024] A heating pipe is provided in the gas heating tank 2, and the power of the heating pipe is 3KW.
[0025] The gas heating tank 2 has a diameter of 300 mm and a height of 500 mm. The liquid storage tank 3 has a diameter of 600 mm and a height of 600 mm. The reaction tube 4 has a diameter of 50 mm and a length of 2000 mm. The aqueous solution tank 7 has a diameter of 600 mm and a height of 400 mm.
[0026] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
