Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically a steam heating device. Background Technology

[0002] Steam heaters are used in air separation equipment and are widely used in petrochemical, food and metallurgical industries. The most important factor for the long-term safe and stable operation of air separation units is the efficient utilization of molecular sieves, and steam heaters play a crucial role in the long-term use of molecular sieves. They mainly use the heat released by steam to heat the required process gas. The regeneration gas flows outside the steam and is separated by pipelines for heat exchange.

[0003] Existing steam heaters cannot fully utilize the heat dissipated by steam, and when the regenerated gas heat exchange temperature is sufficient, they cannot control the amount of steam entering, resulting in low heat exchange efficiency and wasted steam heat. Utility Model Content

[0004] The purpose of this invention is to provide a steam heating device that has the advantages of extending the residence time of steam and regenerated gas, improving heat exchange efficiency and reducing steam waste, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A steam heating device, comprising a cabinet and a heating box. Two L-shaped sliding blocks are symmetrically installed on the lower end of the left side panel inside the cabinet. The heating box is slidably mounted on the two L-shaped sliding blocks. Two sets of fixing buckles are symmetrically installed on the front ends of the left and right sides of the heating box. The two sets of fixing buckles are fixed to the cabinet side panel by screws. Four heat exchange cylinders are equidistantly installed inside the heating box. Guide plates are staggered from top to bottom inside the four heat exchange cylinders. Air inlet pipes are connected to the top of the four heat exchange cylinders. The upper ends of all four air inlet pipes extend out of the top of the cabinet and connect to the main air inlet pipe. Electric valves are installed on all four air inlet pipes. Condensate pipes are connected to the bottom of the four heat exchange cylinders. The lower ends of all four condensate pipes extend out of the heating box and connect to the main water outlet pipe. The outlet of the main water outlet pipe extends out of the cabinet.

[0006] Preferably, the cabinet has four feet arranged in a rectangular array at its bottom corners. These four feet provide stable support for the cabinet.

[0007] Preferably, the heating chamber has an air outlet at the lower left side and an air inlet at the upper right side, with both the air outlet and inlet extending out of the cabinet. The presence of the air inlet and outlet facilitates the entry and exit of regenerated gas into and out of the heating chamber.

[0008] Preferably, a temperature sensor is installed on the upper left side of the heating chamber. By setting a stable sensor, the heating temperature of the regenerated gas inside the heating chamber can be monitored.

[0009] Preferably, three partition plates are installed alternately on the top and bottom plates inside the heating chamber, located between the four heat exchange cylinders. By setting three partition plates, a longer residence time of the regenerated gas is achieved inside the heating chamber.

[0010] Preferably, the cabinet door is hinged at the lower front end of the cabinet and has a handle and a safety lock. The cabinet door facilitates the inspection and maintenance of the equipment inside the cabinet.

[0011] Preferably, a control panel is embedded in the upper right corner of the front panel of the cabinet. The control panel is connected to the four electric valves and to the temperature sensor for signal transmission. By setting up the control panel, it is possible to easily control the opening and closing of the four electric valves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In use, steam enters the heat exchange cylinder, and the guide plate prolongs the time the steam spends in the heat exchange cylinder, allowing the steam to fully dissipate its heat and heat the heat exchange cylinder. Regenerated gas enters the heating chamber from the inlet, and three partition plates prolong the residence time of the regenerated gas in the heating chamber, allowing the regenerated gas to fully absorb the heat emitted by the heat exchange cylinder and exchange heat with it, thus improving the heat exchange efficiency. During the heat exchange process, the temperature sensor transmits the temperature of the heating exhaust end to the control panel in real time. When the temperature is too high, it indicates that the heat exchange temperature of the regenerated gas is sufficient, and one electric valve can be closed appropriately to stop the intake of one of the heat exchange cylinders for heat exchange, reducing steam waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 2 This utility model provides a technical solution for a steam heating device: a steam heating device includes a cabinet 1 and a heating box 2. Four feet 16 are installed in a rectangular array at the four corners of the bottom of the cabinet 1. Two L-shaped slides 7 are symmetrically installed on the lower end of the left side panel inside the cabinet 1. The heating box 2 is slidably mounted on the two L-shaped slides 7. Two sets of fixing buckles 9 are symmetrically installed on the left and right front ends of the heating box 2. The two sets of fixing buckles 9 are fixed to the side panel of the cabinet 1 by screws. Four heat exchange cylinders 3 are equidistantly installed inside the heating box 2. Guide plates 10 are staggered from top to bottom inside the four heat exchange cylinders 3. Air inlet pipes 12 are connected to the top of the four heat exchange cylinders 3. All four ends of the steam tank 1 extend out of the top of the cabinet 1 and are connected to the main air inlet pipe 14. All four air inlet pipes 12 are equipped with electric valves 13. The bottom of the four heat exchange cylinders 3 are connected to condensate pipes 5. The lower ends of the four condensate pipes 5 extend out of the heating box 2 and are connected to the main water outlet pipe 4. The outlet of the main water outlet pipe 4 extends out of the cabinet 1. When in use, steam enters from the main air inlet pipe 14 and then enters the heat exchange cylinder 3 through the four air inlet pipes 12. The guide plate 10 prolongs the time of steam in the heat exchange cylinder 3, so that the heat of the steam is fully dissipated to heat the heat exchange cylinder 3. The condensate produced by the steam condensation enters and exits through the four condensate pipes 5 and finally enters the main water outlet pipe 4 for discharge.

[0019] The heating box 2 has an air outlet 8 at the lower left end and an air inlet 15 at the upper right end. Both the air outlet 8 and the air inlet 15 extend out of the cabinet 1. Inside the heating box 2, on the top and bottom plates, three partition plates 6 are installed alternately between the four heat exchange cylinders 3. The regenerated gas enters the heating box 2 through the air inlet 15. The three partition plates 6 extend the residence time of the regenerated gas in the heating box 2, so that the regenerated gas can fully absorb the heat emitted by the heat exchange cylinders 3 and exchange heat with it. After heat exchange, it is discharged from the air outlet 8.

[0020] A temperature sensor 11 is installed on the upper left side of the heating box 2. A cabinet door 17 is installed on the lower front of the cabinet 1 by hinges. The cabinet door 17 is equipped with a handle and a safety lock. A control panel 18 is embedded in the upper right corner of the front panel of the cabinet 1. The control panel 18 is connected to four electric valves 13 for control and to the temperature sensor 11 for signal transmission. During the heat exchange process, the temperature sensor 11 will transmit the temperature of the exhaust end of the heating box 2 to the control panel 18 in real time. When the temperature is too high, it means that the heat exchange temperature of the regenerated gas is sufficient. One electric valve 13 can be closed appropriately to stop the gas intake of one of the heat exchange cylinders 3 for heat exchange.

[0021] In use, steam enters from the main inlet pipe 14 and then enters the heat exchange cylinder 3 through four inlet pipes 12. The guide plate 10 prolongs the time the steam spends in the heat exchange cylinder 3, allowing the steam to fully dissipate its heat and heat the heat exchange cylinder 3. The condensate produced by the steam condensation enters and exits through four condensate pipes 5 and finally enters the main outlet pipe 4 for discharge. The regenerated gas enters the heating box 2 from the inlet 15. The three partition plates 6 prolong the residence time of the regenerated gas in the heating box 2, allowing the regenerated gas to fully absorb the heat emitted by the heat exchange cylinder 3 and exchange heat with it. After heat exchange, it is discharged from the outlet 8. During the heat exchange process, the temperature sensor 11 transmits the temperature of the exhaust end of the heating box 2 to the control panel 18 in real time. When the temperature is too high, it indicates that the heat exchange temperature of the regenerated gas is sufficient. One electric valve 13 can be closed appropriately to stop the intake of one of the heat exchange cylinders 3 for heat exchange.
