[0036] With the development of society, people pay more and more attention to environmental protection. In order to reduce the emission of sulfur dioxide, in order to solve the problem of acid rain, it is necessary to carry out desulfurization treatment on the discharged flue gas in industrial production. According to the relevant provisions, a flue gas monitoring device needs to be arranged in the desulfurization system, which is used to evaluate the desulfurization effect according to the collected data, and only when the desulfurization effect meets the specified requirements, the desulfurized flue gas can be discharged.

[0037] The compressed air station is an important part of the desulfurization system, and is used to provide compressed air. The accuracy of the data collected by the flue gas monitoring device can be affected by the stability of the compressed air. If the compressed air station cannot provide stable compressed air, the data collected by the flue gas monitoring device will be distorted. Therefore, it is necessary to take necessary improvement measures for the compressed air station to ensure that the compressed air station can provide stable compressed air.

[0038] Based on this, the first aspect of the embodiments of the present application provides a compressed air station, which aims to enable the compressed air station to provide stable compressed air, so that the data collected by the flue gas monitoring device will not be distorted.

[0039] As shown in Figure 1 The compressed air station 100 in the embodiments of the present application includes a first booster 110, a second booster 120, an air tank 130, and a first three-way valve 140. Specifically, the first booster 110 has a first air inlet end 111 and a first air outlet end 112, the second booster 120 has a second air inlet end 121 and a second air outlet end 122, the air tank 130 has an air inlet 131 and an air outlet 132, and the air outlet 132 is used to provide compressed air. The first air outlet end 112, the second air outlet end 122, and the air inlet 131 are all connected with the first three-way valve 140. Among them, the first three-way valve 140 has a first state and a second state that can be switched with each other. When the first three-way valve 140 is in the first state, the first air outlet end 112 of the first booster 110 is in communication with the air inlet 131 of the air tank 130. When the first three-way valve 140 is in the second state, the second air outlet end 122 of the second booster 120 is in communication with the air inlet 131 of the air tank 130.

[0040] The compressed air station 100 in the related art only has one booster, and the failure of the booster is the main reason for the fluctuation of the compressed air.

[0041] The compressed air station 100 in the embodiment of the present application is provided with a first pressure increasing device 110, a second pressure increasing device 120 and a first three-way valve 140. When the first three-way valve 140 is in a first state, the first pressure increasing device 110 is in communication with the gas storage tank 130, at this time, the first pressure increasing device 110 serves as the currently used equipment, and the second pressure increasing device 120 serves as the standby equipment. When the first three-way valve 140 is in a second state, the second pressure increasing device 120 is in communication with the gas storage tank 130, at this time, the second pressure increasing device 120 serves as the currently used equipment, and the first pressure increasing device 110 serves as the standby equipment. In this way, the pressure increasing devices in the compressed air station form a one-use-one-backup situation, and once the currently used pressure increasing device fails, another pressure increasing device can be quickly adjusted for use. Thus, the compressed air station 100 can always provide relatively stable compressed air to ensure that the data collected by the flue gas monitoring device is not distorted.

[0042] In some embodiments, the compressed air station 100 further comprises an air inlet pipeline 150 and a second three-way valve 160, the first air inlet end 111, the second air inlet end 121 and the air inlet pipeline 150 are all connected with the second three-way valve 160. The second three-way valve 160 has a third state and a fourth state which can be switched with each other. When the second three-way valve 160 is in the third state, the air inlet pipeline 150 is in communication with the first air inlet end 111 of the first pressure increasing device 110, and when the second three-way valve 160 is in the fourth state, the air inlet pipeline 150 is in communication with the second air inlet end 121 of the second pressure increasing device 120.

[0043] In the embodiment, the air inlet pipeline 150 is connected with the second three-way valve 160, and the second three-way valve 160 is also connected with the first air inlet end 111 of the first pressure increasing device 110 and the second air inlet end 121 of the second pressure increasing device 120. By adjusting the state of the second three-way valve 160, the air inlet pipeline 150 can be controlled to be in communication with the first pressure increasing device 110 or the second pressure increasing device 120. Specifically, in the case that the first pressure increasing device 110 works, the second three-way valve 160 needs to be controlled to make the air inlet pipeline in communication with the first pressure increasing device 110, and in the case that the second pressure increasing device 120 works, the second three-way valve 160 needs to be controlled to make the air inlet pipeline in communication with the second pressure increasing device 120. Thus, as the total air inlet side of the compressed air station 100, the air inlet pipeline can always be in a communication state with the currently used pressure increasing device.

[0044] In some embodiments, the first outlet 112 is connected to the first three-way valve 140 through a first connecting pipeline 170, and the second outlet 122 is connected to the first three-way valve 140 through a second connecting pipeline 180. That is, the first connecting pipeline 170 is arranged between the first supercharging device 110 and the first three-way valve 140, and the second connecting pipeline 180 is arranged between the second supercharging device 120 and the first three-way valve 140. In this way, the first supercharging device 110 and the second supercharging device 120 can be kept at a certain distance from the gas storage tank 130 through the first connecting pipeline 170 and the second connecting pipeline 180, so that the first supercharging device 110, the second supercharging device 120, and the gas storage tank 130 can each have sufficient layout space.

[0045] In some embodiments, the first supercharging device 110 and the second supercharging device 120 are air supercharging pumps or supercharging fans. The air supercharging pumps or supercharging fans can compress normal-pressure air into supercharged air when working.

[0046] The embodiments of the second aspect of the present application provide a desulfurization system, which includes the compressed air station 100 in any of the above embodiments.

[0047] The desulfurization system in the embodiments of the present application and the compressed air station 100 in the above embodiments have the same application concept, and thus the desulfurization system in the embodiments of the present application can obtain all the beneficial effects of the compressed air station 100 in the above embodiments.

[0048] In some embodiments, as shown in FIG. 2, the desulfurization system further includes a desulfurization reaction tower 200 and a desulfurization agent supply device 300, wherein the gas outlet 132 of the gas storage tank 130 is connected to an inlet of the desulfurization reaction tower 200, and the desulfurization agent supply device 300 is connected to the desulfurization reaction tower 200 through a feeding pipeline 310. Figure 2

[0049] The gas inlet side of the compressed air station 100 can be connected to flue gas to be desulfurized. After the flue gas is supercharged by the compressed air station 100, the flue gas enters the desulfurization reaction tower 200. The desulfurization reaction tower 200 can be a dry desulfurization reaction tower. The desulfurization agent supply device 300 delivers powdered desulfurization agent into the desulfurization tower through the feeding pipeline 310. The desulfurization agent contacts the flue gas in the desulfurization reaction tower 200, thereby absorbing sulfur dioxide and sulfur trioxide in the flue gas.

[0050] In some embodiments, the desulfurization system further includes a first flue gas monitoring device 400 and a second flue gas monitoring device 420. The first flue gas monitoring device 400 is arranged on the upstream side of the compressed air station 100, and the second flue gas monitoring device 420 is arranged on the downstream side of the desulfurization reaction tower 200.

[0051] ​The first flue gas monitoring device 400 and the second flue gas monitoring device 420 are respectively used for detecting relevant data of the flue gas before desulfurization and the flue gas after desulfurization, so as to evaluate the desulfurization effect.

[0052] Further, the first flue gas monitoring device 400 comprises a first sulfur dioxide sensor, a first pressure sensor, a first temperature sensor and a first flow sensor. The second flue gas monitoring device 420 comprises a second sulfur dioxide sensor, a second pressure sensor, a second temperature sensor and a second flow sensor. The first sulfur dioxide sensor and the second sulfur dioxide sensor are used for detecting the content of sulfur dioxide, the first pressure sensor and the second pressure sensor are used for detecting the pressure, the first temperature sensor and the second temperature sensor are used for detecting the temperature of the flue gas, and the first flow sensor and the second flow sensor are used for detecting the flow. The content of sulfur dioxide, the pressure, the temperature and the flow are all used as the evaluation data of the environmental protection parameters. By monitoring the above environmental protection parameters, the desulfurization effect of the desulfurization system can be comprehensively evaluated.

[0053] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
