Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology for gas storage tanks, specifically a high-efficiency and environmentally friendly waste heat recovery structure for gas storage tanks. Background Technology

[0002] A gas storage tank is a device specifically used to store gas and also serves to stabilize system pressure. Based on the pressure it can withstand, gas storage tanks can be divided into high-pressure gas storage tanks, low-pressure gas storage tanks, and atmospheric pressure gas storage tanks.

[0003] When storing gas in existing gas storage tanks, the gas is sent into the tank by an air compressor. This compression of the gas does work, which is then converted into the gas's internal energy, increasing its internal energy and raising its temperature. At the same time, factors such as the thermal motion of gas molecules, friction during gas flow, and exothermic chemical reactions also contribute to the increase in the internal temperature of the gas storage tank, thus affecting its storage condition.

[0004] Most existing methods for cooling gas storage tanks involve natural heat dissipation, air cooling, and water cooling. However, these methods have limitations, resulting in poor heat dissipation and specific requirements for the site environment and heat dissipation medium. Consequently, the waste heat generated by the gas storage tank cannot be effectively utilized, leading to resource waste. Furthermore, some of the waste heat is directly released into the air, which can increase greenhouse gases and negatively impact the environment.

[0005] Therefore, it is necessary to propose a high-efficiency and environmentally friendly waste heat recovery structure for gas storage tanks. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-efficiency and environmentally friendly waste heat recovery structure for gas storage tanks. It has the advantages of effectively utilizing waste heat, reducing energy waste, and avoiding direct emission of waste heat, thus solving the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a high-efficiency and environmentally friendly waste heat recovery structure for a gas storage tank, comprising a gas storage tank and a water tank:

[0008] The gas storage tank has a slot, and a heating box is welded inside the slot;

[0009] The heating chamber has a heating cavity inside, and a copper alloy plate is welded to the bottom of the heating cavity. The copper alloy plate is placed inside the gas storage tank, and a heat-absorbing plate is installed on the copper alloy plate. One end of the heat-absorbing plate extends into the interior of the gas storage tank, and the other end of the heat-absorbing plate extends into the interior of the heating cavity.

[0010] Preferably, the water tank is provided with a cold water storage chamber and a hot water storage chamber. A submersible pump is installed inside the cold water storage chamber. A delivery pipe is installed at one end of the submersible pump. The other end of the delivery pipe is fixedly connected to the inside of the heating chamber. A centrifugal pump is installed on the upper surface of the water tank. An inlet pipe is installed at one end of the centrifugal pump and extends into the inside of the hot water storage chamber. An outlet pipe is installed at the other end of the centrifugal pump and the other end of the outlet pipe is fixedly connected to the inside of the heating chamber.

[0011] Preferably, an inlet pipe is installed on the upper surface of the cold water storage chamber, and a drain pipe is installed on one side of the hot water storage chamber, with a valve installed on the drain pipe.

[0012] Preferably, a temperature sensor is installed at the top of the heating chamber, and multiple sets of heat-absorbing plates are arranged in an orderly manner on the copper alloy plate.

[0013] Preferably, an inlet pipe and an outlet pipe are respectively installed at one end of the gas storage tank, and valves are installed on both the inlet pipe and the outlet pipe.

[0014] Preferably, transparent insulation panels are installed on the sides of both the cold water storage chamber and the hot water storage chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This high-efficiency and environmentally friendly waste heat recovery structure for gas storage tanks works by absorbing heat generated during the release or compression of compressed gas stored in the tank. The heat is absorbed by a heat-absorbing plate and a copper alloy plate. Meanwhile, a submersible pump and a delivery pipe supply cold water from the cold water storage chamber into the heating chamber. The cold water absorbs the heat carried by the heat-absorbing plate and the copper alloy plate, heating itself. A temperature sensor monitors the internal temperature. When the water temperature reaches a certain level, a centrifugal pump, an output pipe, and an inlet pipe supply it to the hot water storage chamber for storage. The heat can then be further absorbed by the submersible pump. The system introduces cold water into the heating chamber, creating a cycle of cold water heating and hot water discharge. This design effectively absorbs the heat generated during the operation of the gas storage tank, and the absorbed heat is reused to heat the water, reducing energy waste and thermal pollution caused by direct discharge of waste heat into the environment. Furthermore, by recovering and utilizing waste heat, dependence on other energy sources is reduced, which helps reduce greenhouse gas emissions and improves the tank's environmental friendliness. The system also lowers the overall temperature of the gas storage tank, helping to slow down the aging and corrosion of the equipment and extend the service life of the gas storage tank and related equipment.
