Since the SF6 gas is expensive and can be decomposed to produce toxic components under the action of electric arc, electric spark and corona discharge. Therefore, after the SF6 electrical equipment is applied for a period of time, the SF6 gas needs to be recovered and refilled with new gas. The SF6 gas recycling vehicle is a special device for recycling and charging SF6 gas when manufacturing and maintaining SF6 electrical equipment. Conventional SF6 gas recovery vehicles are equipped with a stationary liquid storage tank. After the recovery, the liquid SF6 is required to be filled into a special steel cylinder through an air pipe or sent to an SF6 gas recovery and purification treatment center together with a recovery vehicle, and the used SF6 gas is subjected to centralized purification treatment, unified detection and unified management so as to realize the recycling of the SF6 gas. However, filling the liquid SF6 into the steel cylinder is an operation with strong technical requirements, and has certain danger, so that non-professional personnel cannot operate the operation, and the technical requirements on the personnel are high; in addition, the filling of the liquid SF6 into the steel cylinder can be carried out only when the SF6 liquefaction container has a considerable liquid storage capacity, and the liquid SF6 in the liquid storage tank is generally not less than half of the total liquid level, so that the recovered gas cannot be completely filled into the steel cylinder, and more residual gas exists in the liquid storage tank; meanwhile, SF6 gas is compressed to the liquid storage tank, the process operation of filling SF6 in the liquid storage tank to the steel cylinder is complex, the steel cylinder is connected through the gas pipe for gas filling, the gas tightness is difficult to guarantee, series of operations such as vacuumizing are needed to be carried out on the gas pipe, a small amount of gas leakage is easy to occur in the operation process, and the risk of SF6 gas leakage is increased. If the gas is sent to an SF6 gas recovery and purification treatment center together with the recovery vehicle, the recovery vehicle is large in size and heavy, generally the weight is about 1000KG, and the transportation wastes time and labor; in the operation of recovering gas from a plurality of SF6 devices at one time, the capacity of the liquid storage tank is limited, so that the recovery of the whole SF6 device at one time is difficult to complete, and the operation of filling SF6 into a steel bottle is required to be repeated.
SUMMERY OF THE UTILITY MODEL
Therefore, the SF6 gas recovery vehicle with the detachable mobile liquid storage tank is needed to be provided, and the problems that the requirement that the traditional SF6 gas recovery vehicle needs to fill the recovered SF6 gas into a steel cylinder is high, the risk of SF6 leakage is increased, residual gas exists in the liquid storage tank, or the time and labor are wasted when the recovery vehicle is sent to a purification treatment center are solved.
