Description

Technical Field

[0001] The present application relates to the technical field of desulfurization towers, and in particular to a flue gas desulfurization structure for a thermal power plant. Background Art

[0002] A power plant refers to a factory that uses coal, oil, and natural gas as fuel to produce electricity. Its basic production process is that the fuel burns in the boiler to heat water to make steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy, and then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy. When the coal-fired boiler of a thermal power plant is burning, the various organic and inorganic sulfur contained in the coal is converted into sulfur oxides mainly composed of sulfur dioxide. Sulfur dioxide enters the atmosphere and combines with water vapor in the atmosphere to form acid rain, which has a serious impact on ground buildings and crops, and is also harmful to the human body. Therefore, flue gas desulfurization is an important part of environmental protection work.

[0003] During the use of the existing desulfurization device, during the desulfurization process of the traditional flue gas desulfurization tower, the spray layer needs to spray limestone water mist for desulfurization. Due to the small mass of the water mist, it will rise with the flue gas to the demister, and then adhere to the surface of the demister. Long-term use of limestone will accumulate on the surface of the demister, affecting the demisting effect of the demister. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present application provides a flue gas desulfurization structure for a thermal power plant, which has the advantages of easy cleaning, etc., and solves the problem that during the use of the desulfurization device, during the desulfurization process of the traditional flue gas desulfurization tower, the spray layer needs to spray limestone water mist for desulfurization. Since the mass of the water mist is relatively small, it will rise with the flue gas to the demister, and then will adhere to the surface of the demister. Long-term use of limestone will accumulate on the surface of the demister, affecting the demisting effect of the demister.

[0009] Through the above scheme, the base is used to support and stabilize the desulfurization tower.

[0010] Furthermore, an air inlet pipe is fixedly connected to the lower end surface of the desulfurization tower.

[0011] Through the above scheme, the air inlet pipe is used to introduce the gas into the desulfurization tower for desulfurization treatment.

[0012] Furthermore, an air outlet pipe is fixedly connected to the upper end of the desulfurization tower.

[0015] Through the above solution, the water pipe mounting frame is used to support and protect the water pipe, ensuring its stability and safety during use.

[0016] Furthermore, the upper end of the water pipe passes through the side wall of the desulfurization tower and is fixedly connected with a diversion pipe.

[0017] Through the above scheme, the diverter pipe is used to divert the water flow in the water pipe into the desulfurization tower to achieve uniform distribution of the water flow and optimize the desulfurization treatment effect.

[0018] Furthermore, a plurality of mounting tubes are fixedly connected to the surface of the diverter tube, and atomizing nozzles are fixedly connected to the lower ends of the plurality of mounting tubes.

[0019] Through the above scheme, the atomizing nozzle is used to atomize the liquid into fine droplets so as to better mix and react with the gas inside the desulfurization tower, ensuring that the liquid is more evenly distributed inside the desulfurization tower.

[0020] Furthermore, a crossbeam is fixedly connected to the upper end of the desulfurization tower, and two water pipe fixing frames are fixedly connected to the lower end of the crossbeam. The interiors of the two water pipe fixing frames are fixedly connected to the surface of the water pipe.

[0021] Through the above solution, the water pipe fixing frame can firmly install the water pipe inside the desulfurization tower, and at the same time support and protect the water pipe to ensure its stability and safety during use.

[0035] A method for using a flue gas meter controller for a thermal power plant is also provided, comprising the following steps:

[0036] S1: Set the smoke emission concentration threshold. The user sets a smoke emission concentration threshold according to safety standards or personal needs;

[0037] S2: Start the monitoring component, and start the monitoring component of the flue gas meter controller of the thermal power plant to monitor the flue gas emission concentration in real time;

[0038] S3: real-time monitoring of smoke emission concentration, the monitoring component 202 continuously detects the smoke emission concentration in the surrounding environment;

[0039] S4: Determine whether the real-time concentration exceeds the set threshold, and if it is equal to or exceeds the set threshold, proceed to the next step;

[0040] S5: Start the servo motor 203e. When the monitored flue gas emission concentration exceeds the standard, the controller starts the servo motor 203e;

[0041] S6: The servo motor 203e drives the gas cut-off component after receiving the start signal;

[0042] S7: The smoke emission is closed, and the gas shut-off component 203 executes the operation of shutting down the smoke meter body 101, cutting off the smoke emission supply.
