[0025] Embodiment one: please refer to Figs. 1 to 4The utility model provides a kind of technical scheme: a kind of extractable air source backwashing device, comprising: connecting pipeline 1, connecting pipeline 1 bottom side is communicated with the input end of electric control air valve 2, the output end of electric control air valve 2 is communicated with the input end of acid-proof pump 3, the output end of acid-proof pump 3 is communicated with one side of gas storage tank 4, another side of gas storage tank 4 is fixedly inserted with exhaust pipe 5, gas storage tank 4 inside is fixedly connected with baffle 6, baffle 6 top is provided with shower head 7, one end of shower head 7 is fixedly installed on spray pipe frame 8, the output end of liquid pumping pump 9 is communicated with the top of spray pipe frame 8, the input end of liquid pumping pump 9 is communicated with backwashing liquid tank 10.

[0026] when needing to backwash residual acid corrosive gas in connecting pipeline 1 connected with analyzer, by opening electric control air valve 2, under the suction of acid-proof pump 3, gas in connecting pipeline 1 is extracted and transported into gas storage tank 4, when gas enters into gas storage tank 4, backwashing liquid in backwashing liquid tank 10 is extracted into spray pipe frame 8 by liquid pumping pump 9, then is sprayed out through linear array arrangement's shower head 7 in the bottom of spray pipe frame 8, so as to increase the contact area of gas and backwashing liquid, promote sufficient reaction, improve purification effect, further increase the contact area and contact time of gas and backwashing liquid by staggered baffle 6, significantly improve backwashing efficiency, then improve purification effect, beneficial to prolong the service life of analyzer, and the purified gas is discharged through exhaust pipe 5.

[0027] Example two: on the basis of example one, the input end of electric control air valve 2 is communicated with connecting pipeline 1 by corrosion-proof acid-proof pipe 11, the output end of electric control air valve 2 is communicated with the input end of acid-proof pump 3 by corrosion-proof acid-proof pipe 11, the two sides of electric control air valve 2 are fixedly connected with connecting pipeline 1 by fixed bending rod, electric control air valve 2 is made of corrosion-resistant material, electric control air valve 2 is fixed between connecting pipeline 1 by bending rod, the bottom of acid-proof pump 3 is fixedly connected with connecting plate 12, one side of connecting plate 12 is fixedly connected with gas storage tank 4, controller 13 is arranged in the bottom of connecting plate 12, controller 13 is electrically connected between electric control air valve 2 and liquid pumping pump 9, and is fixedly installed in gas storage tank 4 by connecting plate 12, so that connecting plate 12 supports acid-proof pump 3, liquid pumping pump 9 and backwashing liquid tank 10 are all fixedly installed on support frame, one side of controller 13 is fixedly connected with the outer wall of gas storage tank 4, liquid level sensor 14 is installed opposite to controller 13, one end of liquid level sensor 14 is fixedly inserted in gas storage tank 4, electromagnetic valve 15 is arranged in the bottom of liquid level sensor 14, liquid level sensor 14 is convenient for monitoring the internal liquid of gas storage tank 4 by being arranged, electromagnetic valve 15 is fixedly sleeved on liquid discharge pipe 16, the top of liquid discharge pipe 16 is communicated with gas storage tank 4, liquid level sensor 14 is electrically connected with controller 13, and controller 13 is electrically connected with electromagnetic valve 15.

When it is necessary to clean the gas in the connecting pipeline 1, the electrically controlled gas valve 2 is opened by the controller 13, and the acid-proof and corrosion-proof pump 3 is opened, and under the connection of the acid-proof and corrosion-proof pipe 11, the gas in the connecting pipeline 1 is reversely extracted and sent into the gas storage tank 4. At this time, the controller 13 controls the liquid pumping pump 9, and the liquid pumping pump 9 pumps the reverse washing liquid in the reverse washing liquid tank 10 into the spray pipe rack 8, and then the reverse washing liquid is sprayed out through the linear array of the spray heads 7 at the bottom of the spray pipe rack 8, so as to increase the contact area of the gas and the reverse washing liquid, promote sufficient reaction, improve the purification effect, and the gas storage tank 4 is provided with staggered partition plates 6, which can slow down the flow speed of the gas, thereby increasing the residence time of the gas in the gas storage tank 4, further increasing the contact area and contact time of the gas and the reverse washing liquid, significantly improving the reverse washing efficiency, and further improving the purification effect, which is beneficial to prolong the service life of the analyzer. With the continuous spraying of the spray head 7, the reverse washing liquid flows to the bottom of the gas storage tank 4 for accumulation.

[0030] By arranging the filter plate 17, the impurities generated in the reverse washing liquid due to chemical reaction can be filtered when the reverse washing liquid is discharged, thereby facilitating the subsequent treatment of the discharged reverse washing liquid. After the accumulated reverse washing liquid is completely discharged, the impurities deposited on the filter plate 17 can be removed by disassembling the sealing plate 18, thereby facilitating the subsequent filtration of the reverse washing liquid in the reverse washing process. A safety valve 19 is installed on one side of the top of the gas storage tank 4. When the pressure of the gas in the connecting pipeline 1 connected to the gas storage tank 4 through the inlet pipe increases to exceed the standard pressure, the safety valve 19 starts to release pressure, thereby avoiding the danger of excessive pressure in the gas storage tank 4. In addition, a filter is arranged at the gas outlet end of the safety valve 19, thereby filtering the discharged gas and avoiding the discharge of harmful gas.
