Description

Technical Field

[0001] The present invention relates to the field of hydrogen transmission pipelines, and in particular to a high-strength induction heating elbow for hydrogen transmission pipelines. Background Art

[0002] Currently, in hydrogen transportation, excessively high or low temperatures will affect the transportation speed and safety of hydrogen. Therefore, in order to ensure the transportation speed and safety of hydrogen, it is necessary to keep the temperature of the transportation pipeline stable.

[0003] In the prior art, a temperature sensor and a heating coil are installed in the hydrogen transmission pipeline to increase the temperature. When the temperature is detected to be too low, the pipeline is heated.

[0004] Patent: CN118423538A relates to the technical field of hydrogen pipelines, specifically to an induction heating elbow for hydrogen pipelines with impact toughness and a preparation method thereof, comprising an elbow and a protective assembly, the protective assembly comprising a plurality of contraction units, a plurality of energy absorbing plates, a plurality of reinforcing ribs, a heating coil and a temperature sensor. The elbow has a groove, and a plurality of reinforcing ribs are fixedly connected to the elbow. The elbow is installed in the hydrogen pipeline. When hydrogen passes through, the temperature sensor detects the temperature. If the temperature is too low, the heating coil is activated to heat the elbow. At the same time, the reinforcing ribs are located inside the groove to improve the structural strength and toughness of the elbow. The contraction unit supports the energy absorbing plate, which can absorb energy when impacted and struck. At the same time, the contraction unit contracts to achieve a buffering effect. Therefore, under the condition that the elbow is induction heated, it has good impact resistance, greatly improves the toughness of the elbow, and effectively ensures the safety and stability of hydrogen transportation.

[0005] The water cooling heat dissipation effect in the above technology is poor. The water flow effect is poor when water is directly injected into the shell, resulting in poor condensation effect, and the water heated after subsequent condensation cannot be effectively cooled. Simply relying on the heat absorption column to absorb heat will easily lead to poor condensation effect after long-term use. In addition, the heating range of water cooling and electric heating pipes is limited. The position remains unchanged during water cooling and electric heating, resulting in a limited temperature control range, which leads to poor temperature control effect. It is impossible to achieve a more comprehensive temperature control effect for the gas entering the pipeline, and improvement is needed. For this reason, we propose a high-strength induction heating elbow for hydrogen pipelines. Summary of the Invention

[0008] The left side of the curved pipe body is fixedly connected to a water storage tank, a circulation branch pipe is fixedly connected between the water storage tank and the ring pipe 2, a micro pump is provided on the right side of the slider 1, the input end of the micro pump is connected to the interior of the ring pipe 1, the right side of the curved pipe body is located behind the micro pump and is fixedly connected to a diversion chamber, the rear surface of the water storage tank is fixedly connected to two collecting chambers, and a condensation pipe group is fixedly connected between the two collecting chambers and the diversion chamber;

[0009] A temperature sensor is embedded and installed on the right side of the upper surface of the elbow body.

[0010] Furthermore, the outer side wall of the slider 1 and the outer side wall of the slider 2 are both fixedly connected with a sealing strip, and the outer side wall of the sealing strip is in contact with the outer side wall of the elbow body.

[0011] Furthermore, the outer side wall of the elbow body is engaged with two protective shells, and the outer side walls of the two protective shells are fixedly connected with two connecting pieces, and the opposite sides of the two connecting pieces facing each other are detachably connected by bolts.

[0012] Furthermore, a plurality of reinforcing rods are fixedly connected to the lower right side and the right side of the lower surface of the curved pipe body.

[0013] Furthermore, a pneumatic telescopic tube is fixedly connected to the front right side of the elbow body and the front of the lower surface of the elbow body, and a connector is fixedly connected between the pneumatic telescopic tube and the sealing strip.

[0014] Furthermore, an L-shaped bracket is fixedly connected to the left side of the water tank, a micro motor is fixedly connected to the inner side of the L-shaped bracket, and the right end of the output shaft of the micro motor is located inside the water tank and is fixedly connected to a stirring rod.

[0015] Furthermore, a pressure box is fixedly connected to the left side of the water tank above the micro motor, and two solenoid valves are embedded in the front surface of the pressure box. A ventilation pipe is fixedly connected between the solenoid valve and the pneumatic telescopic tube.

[0016] Furthermore, a piston plate is slidably connected to the inside of the air pressure box, a spring is fixedly connected between the piston plate and the air pressure box, an abutment rod is fixedly connected to the lower surface of the piston plate, a cam is fixedly connected to the outer side wall of the output shaft of the micro motor, and the bottom end of the abutment rod passes through the bottom of the air pressure box and fits against the outer side wall of the cam.

[0018] Beneficial effects: By repeatedly inflating and deflating one of the two pneumatic telescopic tubes, the electric heating tube can be controlled to move left and right repeatedly to increase the heating range, or the ring tube can be controlled to move up and down repeatedly, and the elastic spiral tube can be driven to compress or stretch, thereby increasing the water cooling range, making the temperature control range wider and the temperature control effect better. The electric heating tube that moves left and right is used for heating, so that the gas heating range is larger, thereby heating more evenly and ensuring that the gas is heated more completely. The elastic spiral tube that can be contracted and stretched is used to increase the fluidity of the water, so that while the water circulates, a ring-shaped condensation range can be formed to avoid the problem of incomplete condensation.

[0019] When the micro motor is started and the stirring rod is controlled to rotate and stir, the cylinder rotates, and the inclined ring groove toggles the vertical rod to move left and right repeatedly, thereby driving the shielding piece to swing back and forth along the rotating shaft connection at the bottom under the pull of the L-shaped connecting rod, thereby alternately blocking the two docking holes, so that during the micro pump water pumping cycle, the water flow can alternate and intermittently flow along the inside of the two condenser tube groups, increasing the flow time, so that the water condenses better inside the condenser tube group, and strengthens the condensation function of the device on the pipeline. In addition, through the coordinated toggling of the inclined ring groove on the outside of the cylinder, the shielding piece swings at a faster frequency, which can quickly and alternately block the two docking holes, thereby achieving rapid alternating water inflow;

[0020] The temperature sensor is used to sense the internal temperature of the elbow body. When the temperature is too high, the micro pump is started to circulate the condensing water to cool it down. When the temperature is too low, the electric heating tube is started to heat it, thus achieving intelligent temperature control effect.

[0021] When used, the two solenoid valves are used to open alternately to independently control the gas exchange between a group of ventilation pipes, an air pressure box and a pneumatic telescopic tube, thereby independently controlling the left and right reciprocating movement of the electric heating tube, or independently controlling the contraction and extension of the ring tube-compression elastic spiral tube, which is used to cooperate with the start-up of the micro pump or the electric heating tube.
