Abstract

Technical Field

[0002] In the metallurgical industry, oxygen production stations are responsible for providing qualified oxygen and nitrogen products for users such as steelmaking and ironmaking. In order to meet the production needs of users, in some cases, it is necessary to run a liquid pump to supplement the difference. In order to make the liquid gas completely vaporize and enter the gas delivery pipeline, steam water bath vaporizer equipment or circulating hot water water bath vaporizer equipment is generally used to heat the water in the container and exchange heat with the low-temperature liquid gas, so that the low-temperature liquid is vaporized into gas. However, in the actual production process, the use of steam water bath vaporizers will cause steam overflow, causing equipment corrosion, energy waste, and low steam temperature and pressure, insufficient gasification capacity, causing pipeline freezing and cracking and other safety accidents. The use of circulating hot water water bath vaporizers will increase power consumption and increase production costs.
[0003] In addition, all equipment on site needs to be cooled by medium-pressure normal-temperature circulating water (temperature is about 40°C) in the circulating water pool. The water after cooling down will reach about 49°C. The medium-pressure normal-temperature water returning to the circulating water pool needs to go to the cooling tower and be cooled by fans for recycling.
[0004] Therefore, it is necessary to develop a medium-pressure normal temperature water circulation evaporator device to solve this problem. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a medium-pressure normal-temperature water circulation type evaporator device, which not only avoids the problems existing in steam-type water bath evaporators and circulating hot water water bath type evaporators, but also can lower the temperature of medium-pressure normal-temperature circulating water, reduce the number of fans running, and further reduce the power consumption of the equipment.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A further improvement of the technical solution of the utility model is that the water inlet valve adopts a butterfly valve and keeps a normally open state.
[0009] A further improvement of the technical solution of the utility model is that the return valve adopts an automatic valve.
[0010] A further improvement of the technical solution of the utility model is that the diameter of the circulating water inlet pipe is 100 mm.
[0011] A further improvement of the technical solution of the utility model is that the diameter of the circulating water return pipe is 100 mm.
[0012] A further improvement of the technical solution of the utility model is that the distance between the circulating water return pipe and the vaporizer and the bottom of the vaporizer is 50 cm.
[0013] A further improvement of the technical solution of the utility model is that the temperature measuring point is arranged between the connection point between the circulating water return pipe and the vaporizer and the parallel section where the air supply pipe passes through the vaporizer.
[0014] A further improvement of the technical solution of the utility model is that a circulating pump is arranged on the water inlet pipeline, and the water inlet pipeline is connected to the cooling pipeline of each device.
[0015] A further improvement of the technical solution of the utility model is that an outlet valve is arranged on the straight pipe section connecting the liquid pump and the air supply pipe.
[0016] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:
[0017] The utility model provides a medium-pressure normal temperature water circulation type vaporizer device, which heats the water in the vaporizer by steam heating or electric heater to heat the medium-pressure normal temperature circulating water with the liquid gas in the vaporizer, so that the liquid is gasified into gas and enters the gas delivery pipeline for production and use by users. At the same time, after the medium-pressure normal temperature circulating water and the liquid gas in the vaporizer are heat exchanged, the temperature of the medium-pressure normal temperature water will be reduced, and it will flow into the circulating water pool through the circulating water return pipe, which can reduce the circulating water temperature, reduce the number of fan operations, and further reduce the power consumption of the equipment.
