Description

Technical Field

[0001] The invention relates to the technical field of flare towers, and more particularly to a photothermal flare tower in which the chemical energy of combustible gas and solar energy complement each other. Background Art

[0002] The photothermal flare tower that complements the chemical energy of combustible gas with solar energy is a highly efficient and energy-saving device that integrates cogeneration of heat and power with the utilization of new energy. This flare tower fully integrates the chemical energy of combustible gas and solar energy through a unique design, aiming to maximize the utilization of energy and protect the environment. The photothermal flare tower that complements the chemical energy of combustible gas with solar energy is a perfect combination of modern energy technology and environmental protection concepts. Its unique design concept and efficient energy utilization method make it one of the important directions in the future energy field.

[0003] When the existing solar thermal flare tower that complements the chemical energy of combustible gas with solar energy carries out combustible gas combustion heating, it is usually achieved by mixing combustible gas with air and igniting the mixed combustible gas through an igniter to generate heat. However, the existing combustible gas pipelines are all directly sprayed in the burner. When the direct-injection combustible gas pipeline sprays the combustible gas, it is impossible to control the inlet and outlet amounts of the combustible gas, and thus the mixing ratio of air and combustible gas cannot be accurately achieved. This will not only lead to waste of combustible gas, but may also cause incomplete combustion of the combustible gas and discharge it into the air, which will affect the quality of the atmospheric environment. Summary of the invention

[0004] The purpose of the present invention is to provide a photothermal flare tower that complements the chemical energy of combustible gas with solar energy to solve the problems raised in the above background technology:

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A photothermal flare tower for complementing combustible gas chemical energy with solar energy comprises a flare tower body and a heat exchanger arranged on the surface thereof, a burner is fixedly mounted on the top surface of the flare tower body, a mixer is fixedly mounted inside the burner, a fixing rod is fixedly connected between the mixer and the burner, an air duct is fixedly mounted on the bottom surface of the mixer, a pre-storage chamber connected to the air duct is arranged inside the mixer, a mixing chamber is arranged between the pre-storage chamber and the mixer, a plurality of proportioning valves are fixedly mounted between the mixing chamber and the pre-storage chamber, a first fixing block and a second fixing block are fixedly mounted on the inner wall of the mixing chamber and the outer surface of the pre-storage chamber, respectively. A fixed block, an air connecting pipe connected to the pre-storage chamber is fixedly installed on the end surface of the first fixed block, a combustible gas pipeline is fixedly installed on one end surface of the second fixed block, and the end surfaces of the air connecting pipe and the combustible gas pipeline are respectively provided with an air outlet and a combustible gas outlet, the surfaces of the first fixed block and the second fixed block are both fixedly installed with fixing plates, the interiors of the two fixing plates are both slidably connected with guide rods, one end surfaces of the two guide rods are respectively fixedly connected with a first airtight plate and a second airtight plate, the first airtight plate and the second airtight plate are respectively matched with the air outlet and the combustible gas outlet, and the other ends of the two guide rods are fixedly connected with ball heads.

At this time, the air in the pre-storage chamber leaks out from the air outlet through the air connecting pipe, and the combustible gas inside the combustible gas pipeline leaks out from the combustible gas outlet. According to the ratio of air and combustible gas for full combustion in the prior art, the ratio of the first airtight plate and the second airtight plate can be designed. At this time, the air leaked from the air outlet and the combustible gas leaked from the combustible gas outlet are mixed in proportion to each other and enter the mixing chamber, so that the air and the combustible gas are mixed in proportion to each other, thereby achieving full combustion of the combustible gas, reducing the waste of combustible gas, and also reducing the pollution to the atmospheric environment, thereby ensuring the quality of the atmospheric environment.

[0008] Preferably, the surfaces of the two guide rods are respectively sleeved with a first spring and a second spring, one end of the first spring is fixedly connected to the surface of the first airtight plate, the other end of the first spring is fixedly connected to the surface of the fixed plate, one end of the second spring is fixedly connected to the surface of the second airtight plate, and the other end of the second spring is fixedly connected to the surface of the fixed plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1) When the solar thermal torch tower that complements the chemical energy of combustible gas with solar energy is in use, the movable frame moves downward with the moving rod and the trapezoidal block, the ball head is squeezed by the trapezoidal block, and the first airtight plate and the second airtight plate move away from the air outlet and the combustible gas outlet respectively. At this time, the air in the pre-storage chamber leaks out from the air outlet through the air connecting pipe, and the combustible gas inside the combustible gas pipeline leaks out from the combustible gas outlet. According to the ratio of air and combustible gas for full combustion in the prior art, the ratio of the first airtight plate and the second airtight plate can be designed. At this time, the air leaked from the air outlet and the combustible gas leaked from the combustible gas outlet are mixed in proportion to each other and enter the mixing chamber, so that the air and the combustible gas are mixed in proportion to each other, thereby achieving full combustion of the combustible gas, reducing the waste of combustible gas, and also reducing the pollution to the atmospheric environment, thereby ensuring the quality of the atmospheric environment.

[0025] 2) When the solar thermal torch tower that complements the chemical energy of combustible gas with solar energy is in use, the movable frame moves downward with the moving rod and the trapezoidal block. When the trapezoidal block acts on the proportioning valve, the movable frame also moves with the movable rod and the sealing plate. The sealing plate moves away from the air outlet groove, so that the proportioning valve and the air outlet groove are opened at the same time. When the movable frame is reset, the proportioning valve and the air outlet groove are closed at the same time, thereby optimizing the combustion effect and preventing the flame from de-igniting or flashback from damaging the internal components of the mixer, thereby extending the overall service life of the burner.

[0026] 3) When the solar thermal torch tower that complements the chemical energy of combustible gas with solar energy is in use, the inner part of the movable frame is fixedly connected with an outer ring and an inner ring, so that the positions of the sealing plates are staggered with each other, and the positions of the gas outlet grooves are also staggered, which can reduce the ignition time of the igniter and thus reduce the waste of combustible gas.
