Technical Field
The invention relates to the technical field of nitrogen storage tanks, in particular to a nitrogen supply auxiliary system for a storage tank.
Background
The nitrogen storage tank mainly refers to equipment for storing or containing gaseous nitrogen or liquefied nitrogen and other mediums, is widely applied to industries such as chemical industry, petroleum, energy, light industry, environmental protection, pharmacy, food and the like, is used for attenuating pressure fluctuation of a system, realizes balance of air supply and air consumption, and can provide temporary buffer air supply, especially instrument air supply, when a compressor fails.
In the prior art, a tank is generally used to store and supply chemical liquid medicine during the supply of chemicals. To ensure the quality and safety of chemical solutions, nitrogen is generally used to assist in the supply of the tank. However, there are some problems in supplying nitrogen using a tank.
When a tank is in use, the nitrogen pressure above the tank will drop, requiring replenishment of nitrogen. At this time, a valve for introducing nitrogen gas is opened, and nitrogen gas is injected into the storage tank. However, the additional reserve tank is opened simultaneously with the tank being used in order to meet the reserve before reaching the full-liquid reserve state, which may cause mutual interference of the gases between the two tanks, affecting the pressure stability.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention aims to provide a nitrogen supply auxiliary system for a storage tank, which ensures that when two nitrogen valves are opened, no air is mixed between the two storage tanks by installing a one-way valve on each branch, thereby ensuring that the pressure stability of the storage tanks is used and the standby storage tanks synchronously reach the standby state.
The above object of the present invention is achieved by the following technical solutions:
the storage tank nitrogen supply auxiliary system comprises two storage tanks and two one-way valves, wherein the two storage tanks are connected with a material tank through pipelines, and the storage tanks are used for auxiliary supply by filling nitrogen into the material tank;
every install a pressure sensor and a valve that is used for letting in nitrogen gas on the storage tank, the check valve is installed the storage tank with on the pipeline between the material jar, the storage tank is through the check valve orientation the one-way injection nitrogen gas of material jar.
As a further technical scheme of the invention: the pressure sensor is used for monitoring the pressure condition of the storage tank, and when the pressure is lower than a set value, the valve for introducing nitrogen is automatically opened, and the nitrogen is injected into the material tank;
when the pressure is higher than the set value, the valve for introducing nitrogen is automatically closed, and the nitrogen is stopped from being injected into the material tank.
In summary, the present invention includes at least one of the following beneficial technical effects:
the invention discloses a nitrogen auxiliary system for supplying nitrogen to a storage tank, which is characterized in that when a material tank in use needs to be supplemented with nitrogen, a valve for introducing nitrogen on the storage tank is opened, and meanwhile, the valve for introducing nitrogen on a standby storage tank is also opened, but through the arrangement of a one-way valve, no cross gas is ensured between the two storage tanks, the mutual interference of gases between the two storage tanks is avoided, and the opening and closing of the valve for introducing nitrogen are automatically controlled through the arrangement of a pressure sensor. Therefore, the pressure stability of the storage tank can be guaranteed, and meanwhile, the standby storage tank can synchronously reach a standby state, so that the stability and reliability of the whole system are improved.
