Description

Technical Field:

[0001] The utility model relates to the field of industrial production, and particularly relates to a reheating water tank. Background Art:

[0002] A heat exchanger is an energy-saving device for heat transfer between materials among two or more fluids at different temperatures. It enables heat to be transferred from a fluid at a higher temperature to a fluid at a lower temperature, so that the fluid temperature reaches the specified index of the process to meet the requirements of process conditions. It is also one of the main devices for improving energy utilization efficiency. The heat exchanger industry involves nearly 30 industries such as heating ventilation, pressure vessels, medium water treatment equipment, chemical engineering, and petroleum, forming an industrial chain with each other.

[0003] The working process of the liquid nitrogen washing heat exchanger is as follows: at the end of the adsorption period of the adsorber, the molecular sieve is depressurized, and the gas in the molecular sieve is heated through heat exchange in another heat exchanger. After heating, it is vented to the flare system. The working process of the other heat exchanger is as follows: during the regeneration process of the molecular sieve, the low-pressure nitrogen at the outlet of the molecular sieve first flows through the heat exchanger for reheating and then enters the methanol washing as stripping nitrogen. In this way, on the one hand, the methanol loss in the low-temperature methanol washing system is reduced, and on the other hand, the environment can be protected and the impact of methanol on the environment can be reduced.

[0004] The reheating water tank is one of the links in the whole process and serves the purpose of heat exchange for the heat exchanger.

[0005] However, in the northern region, the temperature difference is large. In winter, the concrete powderizes, the water tank is prone to leakage, the steel plate covering the top is not tightly sealed, the on-site water vapor is large, and during the long-term operation of the device, when the water tank needs to be used and leakage occurs at the bottom, maintenance operations cannot be carried out. Since the water tank is outdoors and there is a slight leakage in the pool wall in winter, the leakage point cannot be inspected and repaired.

[0006] Therefore, a reheating water tank that can be airtight and leak-proof and can adapt to the northern climate is needed. Content of the Utility Model:

[0007] The purpose of the utility model is to provide a reheating water tank.

[0008] The utility model is implemented by the following technical solutions:

Each movable cover plate is hinged to the reheating water tank. A positioning hole is arranged on the side wall of the movable cover plate. A positioning rod is slidably connected in the positioning hole. One end of each positioning rod is fixedly connected with a sealing gasket. An arc-shaped groove is arranged on the side wall of each fixed cover plate. The arc-shaped side wall of each sealing gasket is closely attached to the inner wall of the arc-shaped groove. An auxiliary heating pipe penetrates through each fixed cover plate, and the ends of two adjacent auxiliary heating pipes with corresponding axes are fixedly connected by welding.

[0010] Preferably, a first connecting piece is fixedly connected to the edge of the reheating water tank. One side of the bottom end of each movable cover plate is fixedly connected with a second connecting piece. The first connecting piece is hinged to the second connecting piece, and a first sealing gasket is fixedly installed at the top end of the edge of the reheating water tank.
