Description

Technical Field

[0001] The invention belongs to the technical field of containers for storing industrial gases, and in particular relates to an energy-saving wet gas cabinet. Background Art

[0002] A wet gasholder is a device for storing gas, which is mainly composed of a vertical cylindrical water tank, one or more cylindrical tower sections, a bell and a guide device. The bell is a cylindrical structure with an arched bottom and an open bottom. Between the water tank and the bell is a cylindrical movable tower section. The gas pipeline passes through the bottom plate of the water tank and the water in the water tank into the bell to realize the input or discharge of gas; when gas is pressed into the gasholder, the bell rises and its lower hanging ring takes water from the water tank; when the bell rises to a certain height, the lower hanging ring of the bell is connected to the upper hanging ring of the tower section to form a seal, and as the gas is input, the tower section is lifted; when the gas is output, the action process of the bell and the tower section is opposite, and the bell and the tower section rely on guide rails and guide wheels to ensure smooth lifting and lowering.

[0003] Each section of the wet gasholder is sealed with a water-seal annular groove. Its main function is to use the sealing performance of water to isolate the gas inside the gasholder from the external atmosphere, thereby ensuring the sealing and safety of the gasholder. During the operation of the gasholder, the water level in the water-seal groove is automatically adjusted by the change of the internal pressure of the gasholder to ensure that the gasholder can maintain an effective seal under different working conditions. In cold areas, insulation measures must be adopted to prevent the water-seal groove from freezing in winter. The energy consumption in winter is high. When the wet gasholder is operating in winter, special attention should be paid to anti-freeze measures to prevent the water seal and pipeline inside the gasholder from freezing due to low temperature.

[0004] Conventional winter insulation measures include: controlling the water seal temperature: the temperature of the water tank at the bottom of the gas tank can be controlled at an appropriate temperature through a hot water circulation system to prevent freezing; adding insulation materials: selecting insulation materials with low thermal conductivity and good fire resistance to fully insulate all parts of the gas tank to reduce heat loss. It is generally only suitable for ambient temperatures above -5°C and there is a risk of damage from local freezing; heating and heating: heating the water tank of the gas tank with electric heating tape or steam heating to prevent the liquid in the water tank from freezing. The maintenance and use costs are high. In addition, the overflow water produced by steam heating condensation requires further steam heating, which increases the amount of steam used.

[0022] The upper part of the water seal groove is provided with thermal insulation rock wool. When the air temperature is between -5℃ and -10℃, this device can be used alone for antifreeze and heat preservation.

[0023] How it works Before starting the device, check the connection status of the coupling 221 to ensure the transmission stability of the wind power part 24. When the gas tank body is raised, the water seal grooves of each bell cover are separated from the water seal of the gas tank, and an additional heating device is required. The northern region of my country has low temperatures and strong winds. At the same time, the height of the gas tank is high after it is raised and there is basically no shielding from nearby equipment. The wind drives the wind wheel 241 to rotate. The wind wheel 241 is meshed with the gear of the transmission rod 242 through a threaded structure, and then drives the rotating rod 22 to rotate. The rotating rod 22 drives the crankshaft 35 of the air compression device 3 to rotate through the coupling, and the connecting rod on the crankshaft 35 The journal 353 drives the piston handle 34 so that the piston 33 performs work on the air in the compression chamber 321. When the piston 33 moves upward, the air is compressed to generate heat. After the gas pressure increases, the exhaust elastic diaphragm 323 is squeezed to enter the air collecting chamber 31. When the piston moves downward, the intake elastic diaphragm 324 is opened by the atmospheric pressure, and the air enters the compression chamber 321. The hot air in the air collecting chamber 31 is sent to the air tank 41 for storage through the compressed air pipeline 36, and then sent to the water seal groove 12 through the buffer air pipeline 44. At this time, the compressed air can provide heat and kinetic energy for the water in the water seal groove 12. In addition, for the two jackets, the compressed air in the cylinder 32 generates a large amount of heat energy, which heats the cylinder 32, thereby heating the water in the compression jacket 37. The heated water enters the buffer jacket 43 to further heat the compressed air in the gas tank 41. A part of the air in the buffer air pipeline 44 provides power to the pneumatic diaphragm pump 47, so that the water in the compression jacket 37, the buffer jacket 43, the jacket connecting pipeline I 45, and the jacket connecting pipeline II 46 circulates and exchanges heat; When the device is stopped, the coupling 221 can be disassembled, or the vent line 39 can be connected to the low-pressure steam network system and the regulating valve on the pipeline connected to the buffer jacket 43 can be closed.

[0024] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
