Description
Technical Field
The invention relates to the technical field of environment protection and safety of combustible gas, in particular to a zero-leakage non-electrically driven natural gas odorant supplementing device.
Background
In recent years, with the progress of society and the increasing awareness of human environmental protection, natural gas has been widely used as a clean energy source. Since pure natural gas is a colorless and odorless gas, the sense of human body is difficult to perceive. Therefore, before the gas is supplied to users, the gas supply department adds an odorant which is extremely sensitive to human smell into the gas so as to ensure the alertness of people to the gas leakage.
In the prior art, the odorizing process of the fuel gas is that an odorizing machine is added into a fuel gas pipeline, and a storage tank of the odorizing machine has a certain capacity, so that the odorizing machine needs to be supplemented after being consumed. However, the conventional replenishment method is to pressurize the replenishment tank 1 with an inert gas such as nitrogen gas, and then pressurize the tank by pressurizing the odorant into the storage tank of the odorizer. Although the explosion-proof problem of the electric pump supplement mode is solved by the mode, two defects still exist: firstly, a certain fracturing risk exists by pressurizing the replenishing tank 1 body, so that a large amount of odorous agent is leaked; second, the pressurization process requires that the breather valve at the upper end of the storage tank of the odorizer be kept open to maintain air pressure equilibrium, which in turn causes a certain amount of odorous agent to be volatilized at the breather valve, causing air pollution around the natural gas station.
Therefore, how to realize safe and effective odorant supplementation is a technical problem which needs to be solved urgently.
