Description
Technical field
The utility model relates to a kind of natural gas corollary equipment, is specially a kind of natural gas and automatically adds smelly equipment, belongs to sky
Right gas security technology area.
Background technology
With social development, people while focusing on the practicality of equipment, also more focus on equipment the feature of environmental protection and
Convenience.Natural gas, because is its environmental protection and the advantage such as economical and practical gradually replaces coal and oil becomes in industry and life
One of requisite energy.Natural gas main component alkane, wherein methane accounts for the overwhelming majority, separately has a small amount of ethane, propane
And butane, typically there is the rare gas of hydrogen sulfide, carbon dioxide, nitrogen and aqueous vapor and a small amount of carbon monoxide and trace in addition, such as helium
With argon etc..Natural gas is the damp with certain toxicity, is again conveying under stress and use.Due to pipeline and set
It is possible to come into question or improper use when standby material and construction, easily causes leakage, sometimes set off an explosion, catch fire and person poisoning
Danger.Therefore, it is necessary for being realized and then eliminate gas leakage in time by people when there is gas leakage.At present, natural gas
Before delivering to end user, for helping leak detection, also to add smell to natural gas with mercaptan, thiophane etc..Combustion
Gas adds smelly usual employing dropping type device, and dropping type device for adding odor is to put into liquid odorizing agent with the state of drop or thin liquid flow
In gas pipeline, evaporate at this and mix with combustion gas stream.The capacity of odorant storage tank is the odorant amount of a day.From observation tube
The odorant observing inflow per minute drips number, can adjust number of drops by needle valve.Its major advantage is simple structure, and shortcoming is
Manual operation, comparatively laborious.
Utility model content
The purpose of this utility model is to provide for a kind of natural gas and automatically adds smelly equipment, to solve the above-mentioned of prior art
Problem.
The purpose of this utility model is achieved through the following technical solutions.
A kind of natural gas adds smelly equipment automatically, including store storage tank and the PLC of odorant；Described tank top be provided with by
