Example two

When the ambient temperature is-5 ℃, the odor concentration in the odor region B triggers the spray air compressor 1 to be powered on, compressed air is stored in the air storage tank 3, the air compressor 1 is standby when the pressure of the air storage tank 3 reaches 8bar, the air compressor 1 is started when the pressure of the air storage tank 3 is lower than 5bar, the pressure is automatically released when the pressure of the air storage tank 3 is higher than 8bar, the pressure release valve 5 of the air storage tank is opened, the medicine box heating device 37 is normally opened, the standby is higher than 20; when the gas sensor 43 in the area B monitors that the concentration of hydrogen sulfide is higher than 45ppm, the programmable controller 40 in the control system receives an upper limit signal of the gas concentration in the area B, the compressed air removes particles through the air filter 8, the programmable controller 40 authorizes the air pipe electromagnetic valve 15 in the area B to be opened, and the output pressure is adjusted to 4bar through the air pipe pressure valve 16; the air pipe bypass electromagnetic valve 18 is opened, the water pipe electromagnetic valve 25 in the B area is opened, the water pipe pressure valve 26 in the B area adjusts the output pressure to 4bar, compressed air is simultaneously transmitted to the ultrasonic atomization spray head through the air pipe 17 and the water pipe 27 at the pressure of 4bar, the inner wall of the pipeline is heated by using the temperature of the compressed air, and meanwhile, the pipeline 17 and the pipeline 27 and the ultrasonic atomization spray head are dried; after working for 30 seconds, the air pipe bypass electromagnetic valve 18 is closed, the water inlet electromagnetic valve 34, the booster pump 29, the pipeline type heating device 28, the water channel main pipe electromagnetic valve 23 and the B area dosing pump 31 are synchronously opened, tap water passes through the water inlet electromagnetic valve 34 and then is purified through the 1-micrometer-pore multi-stage filter 32 to remove particulate matter impurities, is boosted to above 2bar through the booster pump 29, is heated to 20-30 ℃ through the pipeline type heater 28, is transmitted to the B area water pipe pressure valve 26 through the water channel main pipe electromagnetic valve 23 and the B area water pipe electromagnetic valve 25, and is transmitted to the ultrasonic atomization nozzle after the output pressure of the tap water is adjusted to 2bar through the B area water pipe pressure valve 26.

The dosing pump 31 in zone B is operated according to the following formula 1: 50 concentration, injecting the medicament liquid into a water conveying pipeline 27, and conveying the medicament liquid to the ultrasonic atomization nozzle through the water pipe 27 at a pressure of 2 bar; the gas and liquid mixed by the ultrasonic atomizing nozzle respectively impact the oscillating rod through a 2mm spray hole at the flow rates of 110L/min and 0.5L/min to realize atomization, the diameter of atomized water drops is 3-5 mu m, the atomized water drops are outwards diffused in a conical radial shape under the drive of compressed air, and the atomization length of a single nozzle is 2-5 m. When the gas sensor 43 in the area B monitors that the concentration of hydrogen sulfide is lower than 15ppm, the programmable controller 40 receives a gas concentration lower limit signal in the area B, the water inlet electromagnetic valve 34, the booster pump 29, the pipeline type heating device 28, the water channel main pipe electromagnetic valve 23 and the dosing pump 31 in the area B are synchronously closed, the air pipe bypass electromagnetic valve 18 is opened, the water pipe electromagnetic valve 25 in the area B is opened, the water pipe pressure valve 26 adjusts the output pressure to 4bar, compressed air is simultaneously conveyed to the spray head through the air pipe 17 and the water pipe 27 at the pressure of 4bar, the inner wall of the pipeline is heated by using the temperature of the compressed air, and the pipeline and the spray; after working for 30 seconds, the air pipe bypass electromagnetic valve 18 is closed, the air pipe electromagnetic valve 15 in the area B is closed, the gas concentration control operation is completed, and all the equipment is in standby.
