The tail gas analysis module is with received noise sensor's noise information, also the decibel carries out the height and orders, tail gas analysis module judges, when there is the vehicle weight that gravity sensor sent, noise information reaches the maximum settlement threshold, judge that the vehicle is about to park, in-process parkking, or about to start, in-process starting, then tail gas analysis module retrieves the execution module to tail gas and sends information, tail gas is retrieved the execution module and is controlled the tail gas air exhauster and is increaseed the air extraction volume, with furthest, in the effectual time quantum that the tail gas produced in a large number, collect tail gas.
Preferably, the intelligent optimization system for the gas environment of the gas station further comprises a heat exchanger, an air outlet of the tail gas suction pipe is communicated with a heat source air inlet of the heat exchanger, and a heat source air outlet of the heat exchanger is communicated with the gas storage tank. The geothermal pipe is laid in the oil filling area, the office area and other places on the ground of the gas station, the cold source outlet of the heat exchanger is communicated with the inlet of the geothermal pipe, and the cold source inlet of the heat exchanger is communicated with the outlet of the geothermal pipe. Therefore, gas and liquid in the gas station can obtain heat through the heat exchanger to form cyclic heating and utilize the heat of tail gas, and when the temperature is low, the heated hot water and hot air can supply heat to the ground surfaces of places such as a refueling area and an office area.
Preferably, the intelligent optimization system of gas station gas environment still includes the young system of oil gas recovery, and the young system of oil gas recovery mainly includes: oil gas exhaust fan, oil gas aspiration channel and condensing recovery mechanism. The air suction opening of the oil-gas air suction pipe corresponds to the position of the oil tank cover of the vehicle and approximately corresponds to the height position of the oil tank cover of the vehicle. The oil gas exhaust fan is communicated with the oil gas exhaust pipe, so that gas sucked from an exhaust inlet of the oil gas exhaust pipe enters the condensing type recovery mechanism. The condensing type recovery mechanism can adopt the existing condensing type recovery mechanism and mainly comprises a condensing box and a refrigerating unit which is composed of a compressor, a condenser, an evaporator and the like which are connected together. In the process of refueling and within a period of time after refueling, gasoline vapor dissipated from the oil tank is collected in the condensing tank through the air inlet of the condensing tank through the oil gas exhaust fan and the oil gas exhaust pipe, reusable liquid is formed by the refrigerating unit, and clean gas is discharged through the air outlet of the condensing tank. Specifically, a condensing type oil gas recovery apparatus shown in publication No. CN2651190Y can be used. The oil gas suction pipe can also adopt the tuyere swinging mechanism.
The above embodiments are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should be considered as not departing from the scope of the present invention.
