Description

Technical Field

[0001] The invention relates to the technical field of natural gas hydrogen blending, and in particular to a natural gas hydrogen blending device. Background Art

[0002] With the growing global demand for clean energy and increasing environmental awareness, natural gas hydrogen blending technology has received widespread attention as a transitional clean energy solution. Against this backdrop, the research and development and optimization of natural gas hydrogen blending devices are particularly important. However, there are currently many technical difficulties in this field, and existing natural gas hydrogen blending devices face a series of challenges in practical applications:

[0003] On the one hand, it is difficult for traditional gas mixing devices to achieve a fully uniform mixing of natural gas and hydrogen. In some simple mixing structures, the gas is mixed only by natural flow. Due to the differences in density and molecular size between natural gas and hydrogen, the mixing effect is poor and the composition of the mixed gas is uneven, which affects the combustion efficiency and energy utilization efficiency. Uneven mixed gas may cause problems such as unstable combustion and local overheating during use, which not only reduces the effective utilization of energy, but also may cause safety hazards; on the other hand, impurities such as particles, dust, moisture and other chemical impurities will inevitably be mixed in the production, storage and transportation of hydrogen and natural gas. Existing gas mixing devices often lack effective filtering and purification measures. After these impurities enter the mixed gas, they will cause damage to subsequent equipment, such as blocking pipelines, wearing valves and instruments, etc., increasing equipment maintenance costs, shortening equipment service life, and may even affect the quality and safety of the mixed gas; in addition, during the mixing process of natural gas and hydrogen, temperature has an important influence on the mixing effect and gas performance. However, the existing gas mixing device has defects in the natural gas preheating link and cannot accurately control the preheating temperature and uniformity. Insufficient preheating will result in low activity of gas molecules and slow mixing speed; while excessive preheating may cause adverse reactions such as gas decomposition and polymerization, affecting the stability and quality of the mixed gas and limiting the application of the mixing device under different working conditions.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0033] Specifically, the diffusion component in the natural gas intake mechanism 4 includes a natural gas intake port 401 fixedly connected to the other end of the mixing mechanism 2. The natural gas intake port 401 is the entrance for the natural gas to enter the device. A second disc 402 is fixedly connected to one end of the natural gas intake port 401.

When the natural gas passes through these second dispersion holes 403, it will be dispersed into multiple small airflows, which increases the contact area when the natural gas and hydrogen are mixed, and lays the foundation for more complete mixing later.

Two staggered columns 303 are staggeredly connected to the inner wall of the hydrogen inlet 301. When hydrogen passes through, they can disrupt the gas flow of hydrogen, making it easier for impurities to be intercepted by the filter screen 302, further improving the filtering effect. A valve 304 is fixedly connected to the outer wall of the hydrogen inlet 301. The valve 304 is used to accurately control the flow rate of hydrogen.

The fan blades 407 rotate under the drive of the rotating rod 406, generating a strong airflow, which promotes the further diffusion of the natural gas, so that it can be more evenly distributed before entering the mixing tank 202.

[0044] The preheating assembly includes two support columns 412 fixedly mounted on the upper part of the bottom plate 1, and heating elements 408 are arranged on the upper part of the two support columns 412, and one end of the two heating elements 408 is fixedly connected to a heat-conducting rod 409, and one end of the two heat-conducting rods 409 is fixedly connected to a heat-conducting ring 410, and a plurality of heat-conducting capsules 411 are arranged on the inner wall of the heat-conducting ring 410.

[0045] Specifically, the preheating assembly includes two support columns 412 fixedly mounted on the upper part of the bottom plate 1.

The upper part of the two support columns 412 is provided with the heating element 408, and the heating element 408 can quickly generate heat. One end of the two heating elements 408 is fixedly connected with a heat-conducting rod 409, which can quickly transfer the heat generated by the heating element 408 to the heat-conducting ring 410.

[0046] The heating mechanism 5 includes heat conducting pipes 501 fixedly connected to the upper and lower parts of the outer wall of the heat conducting ring 410, the other ends of the two heat conducting pipes 501 are fixedly connected to the heat conducting plate 1 502, a zigzag heat conducting plate 2 503 is fixedly connected between the two heat conducting plates 1 502, a plurality of heat conducting columns 505 are arranged between the two sides of the heat conducting plate 2 503, and the outer surfaces of the upper and lower parts of the heat conducting plate 2 503 are arranged with arc grooves 504, and the heating mechanism 5 is arranged at the upper and lower ends inside the mixing tank 202;

[0047] Specifically, the heating mechanism 5 includes heat-conducting pipes 501 that are fixedly connected to the upper and lower parts of the outer wall of the heat-conducting ring 410, and can transfer the heat of the heat-conducting ring 410 to the inside of the mixing tank 202. The other ends of the two heat-conducting pipes 501 are fixedly connected with a heat-conducting plate 1 502, and the heat-conducting plate 1 502 can evenly distribute the heat in the mixing tank 202.

A plurality of heat-conducting columns 505 are arranged between the two sides of the heat-conducting plate 2 503, and the heat-conducting columns 505 further enhance the heat-conducting effect, so that the gas in the mixing tank 202 can absorb heat more efficiently.

The heating mechanism 5 is arranged at the upper and lower ends of the mixing tank 202 to ensure that the gas in the mixing tank 202 can be heated comprehensively and evenly.

[0048] The control mechanism 7 includes a fixed column 701 fixedly mounted on the upper part of the bottom plate 1 and away from the mixing mechanism 2, and a control panel 702 is fixedly connected to the upper part of the fixed column 701;

[0049] Specifically, the operator can monitor the operating status of the device in real time through the control panel 702, such as temperature, pressure, gas flow and other parameters, and adjust the working status of each component according to actual needs to achieve precise control of the entire device.

[0050] Multiple electric fans 6 are provided on both sides of the inner wall of the mixing tank 202;

[0051] Specifically, when the electric fan 6 is running, the airflow generated causes the hydrogen and natural gas to form convection in the mixing tank 202, accelerating the gas mixing process. The rotation of the fan promotes the continuous flow of gas, avoiding the situation of excessively high or low local concentration, allowing the hydrogen and natural gas to contact and mix more fully, further improving the uniformity of mixing.

[0052] Working principle: First, hydrogen enters the mixing mechanism 2 through the hydrogen intake mechanism 3. In the hydrogen intake mechanism 3, hydrogen flows in from the hydrogen intake port 301. The impurities in the hydrogen are filtered out by the filter 302 installed at one end of the hydrogen intake port 301. The two staggered columns 303 staggered on the inner wall further disrupt the hydrogen gas flow, making it easier for impurities to be intercepted by the filter 302. The valve 304 on the outer wall is used to control the flow of hydrogen. The hydrogen after preliminary filtration reaches the disc 1 305. The multiple dispersion holes 1 306 inside the disc 1 305 disperse the hydrogen into multiple fine airflows, increasing the contact area when hydrogen and natural gas are mixed, which is conducive to subsequent uniform mixing.

[0053] At the same time, natural gas enters from the natural gas inlet 401, and the disc 2 402 located at one end of the natural gas inlet 401 preliminarily diffuses the natural gas through the multiple dispersion holes 2 403 inside it, so that the natural gas is more evenly distributed when entering the mixing tank 202. The motor 405 on the fixed plate 404 drives the rotating rod 406 to rotate, so that the multiple blades 407 around the outer circle of the rotating rod 406 rotate accordingly, and the airflow generated by the rotation of the blades 407 drives the natural gas to further diffuse, so that it is fully dispersed before entering the mixing tank 202.

[0054] Before the natural gas enters the mixing tank 202, the heating element 408 installed on the two support columns 412 on the upper part of the bottom plate 1 is powered on to generate heat, and the heat is transferred to the heat-conducting ring 410 through the heat-conducting rod 409. The multiple heat-conducting capsules 411 on the inner wall of the heat-conducting ring 410 store and evenly dissipate the heat to preheat the natural gas passing through. The preheated natural gas can increase the molecular activity and speed up the mixing speed with hydrogen, and can also avoid adverse effects caused by temperature changes that may occur during the mixing process, such as gas liquefaction.

[0055] After hydrogen and natural gas enter the mixing tank 202, they are connected to the heat pipe 501 through the heat conduction ring 410, and the heat generated by the preheating assembly is transferred to the heat conduction plate 1 502 and the zigzag heat conduction plate 2 503 inside the mixing tank 202. The multiple heat conduction columns 505 on both sides of the heat conduction plate 2 503 increase the heat conduction area, so that it can more efficiently transfer heat to the gas in the mixing tank 202. At the same time, the arc grooves 504 on the upper and lower outer surfaces of the heat conduction plate 2 503 can guide the hot air flow to flow better in the mixing tank 202, further evenly heat the mixed gas, increase the thermal motion speed of the gas molecules, and promote mixing.

[0056] The airflow generated by the electric fans 6 arranged on both sides of the inner wall of the mixing tank 202 causes the hydrogen and natural gas to form convection in the mixing tank 202, accelerating the gas mixing process. The rotation of the fans promotes the continuous flow of gas, avoiding the situation of excessively high or low local concentration, so that the hydrogen and natural gas can contact and mix more fully.

[0057] By starting the vibration motor 204 fixedly connected to the fixed grooves 203 on both sides of the outer wall of the mixing tank 202, the output end of the vibration motor 204 pushes the fixed grooves 203, thereby causing the mixing tank 202 to vibrate, breaking the laminar state of the gas during the mixing process, so that the hydrogen and natural gas are more fully mixed at the microscopic level. The temperature of the mixed gas is then monitored in real time by the temperature sensor 205 on one side of the upper part of the mixing tank 202, and the temperature data is fed back to the control mechanism 7. If the temperature is too high or too low, the control mechanism 7 can adjust the power of the heating element 408 or control the vibration frequency and amplitude of the vibration motor 204 through the control panel 702 to ensure that the mixing process is carried out under suitable temperature and vibration conditions.

[0058] Through the synergistic effect of various components, hydrogen and natural gas are continuously mixed in the mixing tank 202 to eventually form a uniform mixed gas. After the mixing is completed, the mixed gas can be transported to the subsequent use link through the output pipeline connected to the mixing tank 202. During the entire working process, the control mechanism 7 monitors the operating status of each component in real time, adjusts the parameters according to the actual situation, ensures the stable operation of the device, and efficiently achieves the mixing of natural gas and hydrogen to meet different usage requirements.
