[0002] With the advancement of sustainable development, the proportion of coal consumption in my country's energy consumption structure is declining year by year, and the proportion of clean energy consumption such as natural gas, hydropower, nuclear power, and wind power is increasing year by year. Although my country's energy structure is being further optimized, coal is still the main energy source in the short term, and the use of coal will inevitably emit sulfide (including organic sulfur and inorganic sulfur), nitrogen oxides (NOx) and volatile organic compounds (VOC) and other gases that are harmful to the environment. Excessive sulfide and NOx emissions will also cause photochemical smog, acid rain, ozone layer depletion and haze, destroying the ecological environment and seriously affecting the growth of plants and animals and humans.

[0016] Furthermore, a condensation tube 15 is provided in the condensation dust removal chamber 2, the inlet end of the condensation tube 15 is fixedly connected to the air inlet pipe 12, a water inlet pipe 16 is provided above the condensation tube 15, the water inlet pipe 16 penetrates into the condensation tube 15, and one side of the water inlet pipe 16 penetrates into the condensation tube 15 and is fixedly connected to an atomizing sprayer 17, a drain pipe 18 is connected below the condensation tube 15, and the other side of the drain pipe 18 is connected to the wastewater collection chamber 5, the outlet end of the condensation tube 15 is connected to a ceramic fiber filter 19, and the outlet end pipeline of the ceramic fiber filter 19 is connected to a temperature control valve 20, and the ceramic fiber filter 1 9 is connected to the drain pipe 18, the temperature control valve 20 is fixedly connected to a temperature control sensor 21, the other end of the temperature control valve 20 is connected to the reaction tube 22 in the ozone reaction chamber 3, the inner wall of the condensation and dust removal chamber 2 is fixedly connected to a temperature control device 23, a part of the temperature control device 23 passes through the outer wall of the chassis 1, the temperature control device 23 is connected to the control machine 14 signal, the other end of the water inlet pipe 16 passes through the cavity wall of the condensation and dust removal chamber 2 to connect to the pumping pump 40 in the pumping chamber 9, the input end of the pumping pump 40 is connected to the water storage chamber 6, and the pumping pump 40 is fixedly connected to the pumping chamber 9; Specifically, the temperature control device 23 is composed of a temperature sensor, a temperature controller and a semiconductor refrigeration sheet. The temperature sensor is connected to the temperature controller signal, the temperature controller is connected to the semiconductor refrigeration sheet signal, the temperature controller is connected to the control machine 14 signal, the semiconductor refrigeration sheet and the temperature sensor are both fixed on the inner wall of the condensation and dust removal chamber 2, and the temperature controller is fixed on one side of the outer wall of the chassis 1.
[0017] Specifically, after the temperature sensor measures the indoor temperature, the data is transmitted to the temperature controller, and the temperature controller activates the semiconductor refrigeration sheet to adjust the indoor temperature.
[0018] Specifically, the semiconductor refrigeration sheet also has a heating effect, and the temperature range can be adjusted between -130 degrees and +90 degrees, which can meet the cooling and heating effects of the temperature control device in the overall device.
[0019] Specifically, the control machine 14 controls the temperature control device 23 to control the temperature in the condensation and dust removal chamber 2 to be below W1, so as to achieve the purpose of cooling the flue gas while making the temperature of the condenser tube 15 capable of liquefying the water vapor.
[0020] In this embodiment, the flue gas enters the condensation dust removal chamber 2 through the air inlet pipe 12. When passing through the middle bending part of the condenser tube 15, the water flow, under the action of the water pump 40, passes through the water inlet pipe 16 under the atomizing sprayer 17 to spray water vapor. The water vapor will absorb the smoke particles in the flue gas, and then after contacting the wall of the condenser tube 15, it will be liquefied into water droplets when it is cooled. The water droplets enter the wastewater collection chamber 5 through the drain pipe 18 under the action of gravity. At this time, the atomized water vapor not only takes away the dust particles in the flue gas, but also has a cooling effect on the flue gas. When the flue gas flows through the ceramic fiber filter 19, the ceramic fiber filter 19 can filter the flue gas for a second time. The remaining water vapor and smoke particles are discharged into the drain pipe 18. When the smoke passes through the ceramic fiber filter 19 and flows to the temperature control valve 20, when the temperature control sensor 21 on the temperature control valve 20 detects that the temperature of the smoke is below W2, the temperature control valve 20 is opened to allow the smoke to enter the reaction tube 22 of the ozone reaction chamber 3. When the smoke is not lower than W2 under the detection of the temperature control sensor 21, the control machine 14 controls the temperature control device 23 to continuously lower the indoor temperature, so that the smoke in the condenser 15 reaches a level lower than W2 in a short time, thereby ensuring that in the ozone reaction chamber 3, ozone will not decompose due to the excessively high temperature of the smoke.
[0021] Furthermore, the inlet end of the reaction tube 22 of the ozone reaction chamber 3 is connected to a collection tube 24, and a flue gas analyzer 25 is fixedly connected to one side of the collection tube 24. The flue gas analyzer 25 is connected to the control machine 14 by signal. The upper part of the bent part of the reaction tube 22 is connected to an ozone tube 26, and the other side of the ozone tube 26 is connected to an ozone generator 27 in the ozone generating chamber 10. The outlet end pipeline of the reaction tube 22 is connected to a washing tube 29 in the washing chamber 4. The inner walls of the ozone reaction chamber 3 and the ozone generating chamber 10 are fixedly connected to a temperature control device 28, and a part of the temperature control device 28 passes through the outer wall of the chassis 1, and the temperature control device 28 is connected to the control machine 14 by signal.
[0022] Specifically, the components of the temperature control device 2 28 are the same as those of the temperature control device 1 23 , and the only difference from the temperature control device 1 23 is the indoor temperature control range.
[0023] In this embodiment, after the flue gas is dust-removed and cooled in the condensation dust removal chamber 2, it enters the reaction tube 22 in the ozone reaction chamber 3 within a suitable temperature threshold. After the flue gas flows through the inlet end of the reaction tube 22, a part of it will enter the collection tube 24. At this time, the flue gas analyzer 25 sends a signal to the control machine 14 after detecting the concentration of NOx and SO2 in the flue gas. After processing the corresponding data, the control machine 14 calculates the amount of ozone required to react with the flue gas concentration and controls the ozone generator 27 to produce the corresponding amount of ozone. After being sprayed out through the ozone tube 26, the ozone reacts with the NOx in the flue gas to generate NO2, NO3, N2O5, and O2, all of which are gaseous properties.
[0024] Specifically, due to the particularity of ozone and the particularity of N2O5 generated after ozone and NOx, the overall temperature of the ozone reaction chamber 3 and the ozone generation chamber 10 needs to be controlled between 47 degrees and 150 degrees.
[0025] Specifically, the length of the reaction tube 22 is far enough to meet the length required for the reaction of ozone and NOx at a normal flow rate of flue gas.
[0026] Furthermore, a second collecting pipe 30 is provided on the inlet end of the washing pipe 29 in the washing chamber 4, and a second flue gas analyzer 31 is fixedly connected to the other side of the collecting pipe 30, and the second flue gas analyzer 31 is connected to the control machine 14 by signal. A liquid inlet pipe 32 is connected above the bent portion of the washing pipe 29, and the liquid inlet pipe 32 penetrates into the washing pipe 29, and an end of the liquid inlet pipe 32 that penetrates into the washing pipe 29 is fixedly connected to a second atomizing sprayer 33, and a liquid drain pipe 34 is connected below the bent portion of the washing pipe 29, and the liquid drain pipe 34 is connected to the drain pipe 18, and the washing The outlet end of the tube 29 is connected to a ceramic fiber filter 35, the outlet end of the ceramic fiber filter 35 is connected to the exhaust pipe 13, the bottom of the ceramic fiber filter 35 is connected to the drain pipe 34, the washing chamber 4 is fixedly connected to the inner wall with a temperature control device 3 41, a part of the temperature control device 3 41 passes through the outer wall of the chassis 1, the temperature control device 3 41 is connected to the control machine 14 signal, and the temperature control device 3 41 keeps the overall temperature in the washing chamber 4 constant at W3 under the control of the control machine 14, ensuring that the reaction in the washing tube 29 is not affected by the temperature.
[0027] Specifically, the components of the temperature control device 3 41 are the same as those of the above-mentioned temperature control device 1 23, and the only difference from the temperature control device 1 23 is the indoor temperature control range.
[0028] Specifically, the flue gas enters the sensor chamber of the flue gas analyzer through the collection tube, and enters the electrolytic cell through the permeable membrane, so that the gas diffused and absorbed in the electrolyte is electrolyzed at a specified oxidation potential, and the concentration of the gas is calculated based on the consumed electrolysis current.
[0029] Furthermore, a liquid pump 39 is fixedly connected to the liquid pumping chamber 11 on the left side of the washing chamber 4. The liquid inlet pipe 32 is connected to the liquid pump 39 and then passes through the liquid pumping chamber 11, the ozone generating chamber 10, and the water pumping chamber 9 to be connected to the solution preparation chamber 8. The solution preparation chamber 8 is connected to a flow control valve 36 on the side adjacent to the water storage chamber 6. The flow control valve 36 is fixedly connected to the outer wall of the chassis 1, and the other end of the flow control valve 36 is connected to the water storage chamber 6. The signal of the flow control valve 36 is connected to the control machine 14.

An agitator 38 is arranged on the upper wall of the solution preparation chamber 8, and a part of the agitator 38 penetrates into the water pumping chamber 9. The agitator 38 signal is connected to the control machine 14.
[0030] In this embodiment, after the flue gas has reacted in the ozone reaction chamber 3, it enters the washing chamber 4. After the flue gas enters the inlet end of the washing pipe 29 in the washing chamber 4, a part of the flue gas will flow into the collection pipe 2 30. At this time, the flue gas analyzer 2 31 will analyze the concentrations of NO2, NO3, N2O5, and SO2 in the flue gas, and send the sampling data to the control machine 14. After analyzing the sampling data, the control machine 14 calculates the concentration and amount of the NaOH solution required for dissolution and reaction, controls the flow control valve 1 36 to open, so that the water in the water storage chamber 6 flows into the solution preparation chamber 8, and controls the flow control valve 2 37 to open, so that a certain amount of NaOH high-concentration solution flows into the solution preparation chamber 8. In the liquid preparation chamber 8, the stirrer 38 is rotated to dilute and mix the high-concentration NaOH solution. The mixed NaOH solution is transported to the liquid inlet pipe 32 under the action of the liquid suction pump 39, and finally contacts the flue gas in the washing pipe 29 under the atomization of the atomizing sprayer 33. The atomized NaOH solution absorbs NO2, NO3, N2O5, and SO2 in the flue gas, condenses on the inner wall of the washing pipe 29, and flows into the drain pipe 34 under the action of gravity, and finally enters the wastewater collection chamber 5. When the flue gas flows through the ceramic fiber filter 35, the ceramic fiber filter 35 can filter the unremoved water vapor in the flue gas for a second time, and discharge the condensed water droplets into the drain pipe 34.
