Description

Technical Field

[0001] This utility model relates to the technical field of steam-water separation structure, and in particular to a steam-water separation structure for a steam generator. Background Technology

[0002] A steam generator, also called a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace.

[0003] The existing water-vapor separation device for steam generators (announcement number: CN220061718U) has at least the following drawbacks: after steam enters the device shell, water-vapor separation is performed, but without a gas traction device, only part of the steam that enters the device shell flows out of the device shell after water-vapor separation, and some steam remains inside the device shell, which is not conducive to steam flow and transportation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steam-water separation structure for a steam generator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steam-water separation structure for a steam generator includes a steam generator body, a first separator, and a second separator. An outlet pipe is integrally connected to the top of the steam generator body. One end of the outlet pipe, away from the steam generator body, is bolted to one end of the first separator. The other end of the first separator is bolted to the second separator. The second separator includes an outer casing, a retaining frame, and an adsorption layer. The retaining frame is located inside the outer casing, and several ventilation holes are provided at the ports near both sides of the outer casing. The adsorption layer is located inside the retaining frame, and several drainage holes are provided through the bottom of the retaining frame. A top cover is bolted to the top of the outer casing, and a drain pipe is threaded to the bottom of the outer casing. A gas supply pipe is bolted to the end of the second separator away from the first separator, and a vacuum pump is provided at one end of the gas supply pipe.

[0007] As a further embodiment of this utility model, the air inlet of the air pump is fixedly connected to the tail end of the air delivery pipe, a support frame is provided at the bottom of the air delivery pipe, the air pump is fixedly installed on the top of the support frame, and an exhaust pipe is fixedly connected to the air outlet of the air pump.

[0008] As a further embodiment of this utility model, an electric heating box is provided on the side of the air pump near the air supply pipe. The electric heating box is fixedly installed outside the air supply pipe and fixedly connected to the top of the support frame. The electric heating box includes a heat insulation wrapping layer and a heater.

[0009] As a further embodiment of this utility model, the heater is fixedly connected to the hollow part inside the heat insulation wrapping layer, the inner wall of the heat insulation wrapping layer is attached to the outside of the gas transmission pipe, and the heat insulation wrapping layer is fixedly connected to the inside of the electric heating box.

[0010] As a further embodiment of this utility model, the first separator is located between the second separator and the main body of the steam generator. The first separator includes a separation box, symmetrical corrugated plates, and a drain pipe. Several symmetrical corrugated plates are fixedly connected inside the separation box.

[0011] As a further embodiment of this utility model, the drain pipe is threaded to the bottom of the separation box, and a T-shaped pipe is provided on one side of the bottom of the steam generator body. The two ends of the T-shaped pipe are respectively fixedly connected to the bottom of the drain pipe and the drain tube by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. After passing through the first separator, the steam still contains some water vapor. The steam is guided into the second separator by the air pump. The steam enters the fixed frame through the ventilation hole. The adsorption layer inside the fixed frame adsorbs the water vapor contained in the steam and removes some of the water vapor. The adsorption layer is made of water-absorbing material. When the adsorption layer is full of water vapor, the water vapor condenses into water droplets and enters the drain pipe through the drain hole for unified discharge, avoiding the accumulation of water vapor that cannot be discharged and will affect the secondary steam-water separation.

[0014] 2. The main body of the steam generator produces steam. The air pump operates to extract the steam, which enters the first separator through the outlet pipe. When the steam passes through the symmetrical corrugated plates, the water vapor contained in the steam adheres to the symmetrical corrugated plates and the inner wall of the separator. The water vapor converges to form a water flow. The symmetrical corrugated plates are symmetrically inclined to guide the water flow, making it easier for the water to slide down and be discharged through the drain pipe. Because the air pump extracts the steam, it has a traction force on the flowing steam, preventing the steam from splitting due to the drain pipe and affecting the steam delivery.

[0023] Reference Figures 1-4A steam-water separation structure for a steam generator includes a steam generator body 1, a first separator 2, and a second separator 3. An outlet pipe 101 is integrally connected to the top of the steam generator body 1. One end of the outlet pipe 101, away from the steam generator body 1, is bolted to one end of the first separator 2. The other end of the first separator 2 is bolted to the second separator 3. The second separator 3 includes an outer casing 301, a retaining frame 302, and an adsorption layer 305. The retaining frame 302 is located on the outer casing. Inside the box 301, the fixed frame 302 is provided with several ventilation holes 303 at the ports on both sides of the outer box 301. The adsorption layer 305 is located inside the fixed frame 302. Several drainage holes 304 are provided through the bottom of the fixed frame 302. The top of the outer box 301 is fixedly connected to the cover 306 by bolts. The bottom of the outer box 301 is threadedly connected to the drain pipe 307. The end of the second separator 3 away from the first separator 2 is fixedly connected to the air supply pipe 5 by bolts. One end of the air supply pipe 5 is equipped with an air pump 7.

[0024] During use, after the steam passes through the first separator 2, it still contains some water vapor. The steam is guided into the second separator 3 by the air pump 7. The steam enters the fixed frame 302 through the ventilation hole 303. The adsorption layer 305 inside the fixed frame 302 adsorbs the water vapor contained in the steam and removes some of the water vapor. The adsorption layer 305 is made of water-absorbing material. When the adsorption layer 305 is full of water vapor, the water vapor condenses into water droplets and passes through the drain hole 304 into the drain pipe 307 for unified discharge, avoiding the accumulation of water vapor that cannot be discharged and affects the secondary steam-water separation.

[0025] In this embodiment, the air inlet of the air pump 7 is fixedly connected to the tail end of the air supply pipe 5, the bottom of the air supply pipe 5 is provided with a support frame 9, the air pump 7 is fixedly installed on the top of the support frame 9, and the air outlet of the air pump 7 is fixedly connected to an exhaust pipe 8.

[0026] When in use, the suction force generated by the vacuum pump 7 through negative pressure will significantly reduce the flow resistance of the branch pipe, causing steam to flow preferentially to that branch. When the vacuum pump 7 starts, its powerful suction volume will create a local low-pressure area, attracting more steam into the gas transmission pipe 5, thereby reducing the steam flow of the drain pipe 203 and drain pipe 307 of the first separator 2 and the second separator 3, or even completely blocking the steam flow to the drain pipe 203 and drain pipe 307 of the first separator 2 and the second separator 3.

[0027] In this embodiment, an electric heating box 6 is provided on the side of the air pump 7 near the air supply pipe 5. The electric heating box 6 is fixedly installed outside the air supply pipe 5 and is fixedly connected to the top of the support frame 9. The electric heating box 6 includes a heat insulation wrapping layer 601 and a heater 602.

[0028] In use, steam passes through the second separator 3 to remove water vapor and then enters the gas delivery pipe 5. The electric heating box 6 outside the gas delivery pipe 5 is started, and the heater 602 operates to heat the gas delivery pipe 5. The heat is passed through the gas delivery pipe 5 to heat the steam, thus preventing the steam from cooling down after steam-water separation.

[0029] In this embodiment, the heater 602 is fixedly connected to the central hole inside the heat insulation wrapping layer 601, the inner wall of the heat insulation wrapping layer 601 is attached to the outside of the gas supply pipe 5, and the heat insulation wrapping layer 601 is fixedly connected to the inside of the electric heating box 6.

[0030] In use, to prevent the heater 602 from dissipating heat and affecting the heating of the gas pipeline 5 during operation, a heat insulation layer 601 is provided between the gas pipeline 5 and the heater 602. The heat insulation layer 601 has excellent heat insulation performance, which can effectively reduce the heat dissipation generated by the heater 602 and withstand high temperature. The heater 602 is located inside the heat insulation layer 601, and the inner wall of the heat insulation layer 601 is in close contact with the gas pipeline 5, so as to concentrate the heat dissipated by the heater 602 during operation and transfer it to the gas pipeline 5, thus preventing the heat from dissipating and affecting the heating effect.

[0031] In this embodiment, the first separator 2 is located between the second separator 3 and the main body 1 of the steam generator. The first separator 2 includes a separation box 201, symmetrical corrugated plates 202 and a drain pipe 203. Several symmetrical corrugated plates 202 are fixedly connected inside the separation box 201.

[0032] In use, the main body of the steam generator 1 operates to generate steam, and the vacuum pump 7 operates to extract the steam. The steam enters the first separator 2 through the exhaust pipe 101. When the steam passes through the symmetrical corrugated plate 202, the water vapor contained in the steam adheres to the inner wall of the symmetrical corrugated plate 202 and the separator 201. The water vapor gathers to form a water flow. The surface of the symmetrical corrugated plate 202 has arc-shaped grooves and is symmetrically inclined to guide the water flow, so that the water flow slides down to the lowest point and enters the drain pipe 203 for discharge. Because the vacuum pump 7 extracts the steam, it has a traction force on the flowing steam, which prevents the steam from splitting due to the drain pipe 203 and affecting the steam delivery.

[0033] In this embodiment, the drain pipe 203 is threaded to the bottom of the separation box 201, and a T-shaped pipe 4 is provided on one side of the bottom of the steam generator body 1. The two ends of the T-shaped pipe 4 are respectively fixedly connected to the bottom of the drain pipe 203 and the drain pipe 307 by bolts.

[0034] In use, the water flow generated by the water vapor separation in the first separator 2 and the second separator 3 flows into the T-pipe 4 through the drain pipe 203 and the drain pipe 307, so that the water flow converges for unified discharge. The drain pipe 203 and the drain pipe 307 are both detachable, which makes it convenient for staff to disassemble and inspect the first separator 2 and the second separator 3 regularly.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The main body 1 of the steam generator generates steam, the vacuum pump 7 operates to extract the steam, and the steam enters the first separator 2 through the outlet pipe 101. When the steam passes through the symmetrical corrugated plate 202, the water vapor contained in the steam adheres to the inner wall of the symmetrical corrugated plate 202 and the separator 201, and the water vapor gathers to form a water flow. The symmetrical corrugated plate 202 is inclined to guide the water flow, making it easier for the water flow to slide down and be discharged through the drain pipe 203. Because the vacuum pump 7 extracts the steam, it has a traction force on the flowing steam, avoiding the steam from splitting its flow due to the drain pipe 203, which would affect the steam delivery. After the steam passes through the first separator 2, it still contains some water vapor. The steam passes through the vacuum pump 7 to extract the water vapor. The steam is guided into the second separator 3 by the air pump 7. The steam enters the stationary frame 302 through the ventilation hole 303. The adsorption layer 305 inside the stationary frame 302 adsorbs the water vapor contained in the steam and removes some of the water vapor. The adsorption layer 305 is made of water-absorbing material. When the adsorption layer 305 is full of water vapor, the water vapor condenses into water droplets and passes through the drain hole 304 into the drain pipe 307 for unified discharge. This avoids the water vapor from accumulating and being unable to be discharged, which would affect the secondary steam-water separation. After the steam passes through the second separator 3 to remove the water vapor, it enters the gas delivery pipe 5. The electric heating box 6 outside the gas delivery pipe 5 is started, and the heater 602 operates to heat the gas delivery pipe 5. The heat is passed through the gas delivery pipe 5 to heat the steam, preventing the steam from cooling down after steam-water separation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
