Abstract

Technical Field
[0001] The utility model belongs to the technical field of nitrogen gas storage, and particularly relates to a nitrogen gas storage tank. Background Art
[0002] Nitrogen is usually a colorless and odorless gas. The density of nitrogen is smaller than that of air. Nitrogen accounts for about 78.12% of the total atmosphere and is the main component of air. Under standard atmospheric pressure, when cooled to -195.8 °C, nitrogen will become a colorless liquid. It is essential in life and production. Its compounds can be used as food or fertilizers. Nitrogen is also one of the raw materials for manufacturing ammonia and nitric acid. Nitrogen is basically an inert gas at ambient temperature and moderate temperatures. Therefore, most metals are easy to handle it. At elevated temperatures, nitrogen may be corrosive to metals and alloys.
[0003] In order to solve the deficiencies of nitrogen storage, a patent with the publication number CN 214147400 discloses an intelligent nitrogen storage tank, which can intuitively observe the remaining amount of liquid nitrogen in the tank body, control the pressure and temperature, and avoid potential safety hazards of explosion in the tank body.
[0004] However, due to the existence of the refrigerator, regular maintenance is required, and the maintenance and use costs are relatively high. In order to reduce the maintenance cost, a nitrogen gas storage tank that realizes temperature control by means of water cooling is designed on this basis. Content of the Utility Model
[0005] In order to solve the problems existing in the prior art, the utility model provides a nitrogen gas storage tank that can effectively reduce the overall temperature of the tank body, realize effective temperature control, reduce the maintenance cost, and reduce the difficulty of internal cleaning.
[0006] To achieve the above object, the utility model provides the following technical solution: A nitrogen gas storage tank includes an external tank body and an internal tank body. A pressure sensor and a temperature sensor are arranged on the inner wall of the internal tank body. A temperature display and a controller are arranged on the surface of the external tank body. Two pipelines are arranged at the top of the internal tank body, and the two pipelines are respectively connected to a feed inlet and a pressure relief valve. The pressure sensor is electrically connected to the controller, the temperature sensor is electrically connected to the temperature display, the temperature display is electrically connected to the controller, the controller is electrically connected to the pressure relief valve. The bottom of the external tank body is fixedly connected to a bracket. A liquid level observation pipeline is arranged at the bottom of the internal tank body, and the liquid level observation pipeline extends outside the external tank body. The external tank body and the internal tank body are connected by a partition arranged in the middle. An inlet is arranged on the external tank body below the partition. A spiral circulation pipeline is arranged on the outer surface of the internal tank body, and a micro water pump is connected to the spiral circulation pipeline. The inlet and outlet of the spiral circulation pipeline are both located below the partition, and the controller is electrically connected to the micro water pump.
[0007] Preferably, the micro water pump is arranged above the partition board.
[0008] Preferably, the cross-section of the spiral circulation pipeline is a rectangular structure, and the inner and outer surfaces of the spiral circulation pipeline are the outer tank body and the inner tank body respectively.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0010] Water is static between the outer tank body and the inner tank body below the partition board, playing a role in real-time cooling to a certain extent.
[0011] When the temperature sensor detects a high temperature, the micro water pump is controlled by the controller. At this time, water can circulate in the spiral circulation pipeline between the outer tank body and the inner tank body. Since the cross-section of the spiral circulation pipeline is a rectangular structure, and the inner and outer surfaces of the spiral circulation pipeline are the outer tank body and the inner tank body respectively, the overall temperature of the tank body can be effectively reduced, the effective control of the temperature is realized, the maintenance cost is reduced, and the internal cleaning difficulty is reduced.
