Description

Technical Field

[0001] The present invention relates to the technical field of deaerator equipment, and particularly to a deaerator with an exhaust gas recovery function and its usage method. Background Art

[0002] With the continuous development and improvement of production technology, the specifications and types of deaerators are also constantly evolving. Among them, spray deaerators have a relatively wide range of applications in multiple fields due to their excellent properties. This deaerator achieves the effect of efficient deaeration through a newly designed structure. However, during the operation of the deaerator, the used heating steam in the deaerator is discharged through the exhaust pipe. Directly discharging the steam not only easily affects the environment near the equipment but also increases energy consumption. The deaerator is not convenient for timely recovery and treatment of the discharged steam and cannot recycle it, resulting in an increase in the operating cost of the equipment.

[0003] Therefore, some models of spray deaerators are set up to solve the problem of inability to recover steam. During the operation of the machine, some water evaporates and combines with the hot steam during the deaeration process and is discharged, which not only causes water resource loss but also fails to fully utilize the heat of the hot steam, resulting in waste of resources and an increase in the operating cost of the machine. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a deaerator with an exhaust gas recovery function and its usage method, including a tank body. A structural frame is fixedly connected to the bottom of the tank body, a partition is fixedly connected to the inner wall of the tank body, a pressure relief valve is fixedly connected to the outer wall of the tank body, a steam inlet valve is fixedly connected to the top of the tank body, a water outlet is opened at the bottom of the tank body, and a plurality of support columns are fixedly connected to the outer wall of the tank body;

[0005] An exhaust gas recovery mechanism, which includes a water tank, a water inlet, a second water inlet, and a pressure pipe for controlling the water inflow, and a heating mechanism for reducing the oxygen content in the water;

[0006] The top of the support column is fixedly connected to the bottom of the water tank, the water inlet is fixedly connected to the outer wall of the water tank, the pressure pipe is fixedly connected to the outer wall of the water tank, and the second water inlet is fixedly connected to the outer wall of the pressure pipe.

[0007] Preferably, a steam pipe is fixedly connected to the inner wall of the tank body. One end of the steam pipe away from the tank body is fixedly connected to a second steam pipe, and a plurality of third steam pipes are fixedly connected to the outer wall of the second steam pipe. A plurality of steam ports are opened on the outer wall of the plurality of third steam pipes.

[0008] Preferably, an outer shell is fixedly connected to the inner wall of the tank body, a water pipe is fixedly connected to the inner wall of the tank body, one end of the water pipe far away from the tank body is fixedly connected with a pressure nozzle, and a plurality of holes are opened at the bottom end of the outer shell.

[0009] Preferably, a water tank is fixedly connected to the tops of a plurality of support columns, and a pressure pipe is fixedly connected to the outer wall of the water tank.

[0010] Preferably, one end of the pressure pipe far away from the water tank is fixedly connected to the tank body, a counterweight sealing block is slidably connected to the inner wall of the pressure pipe, a water port is opened at one end of the pressure pipe close to the water tank, and the water port is connected to the water tank in a penetrating manner.

[0011] Preferably, a water groove is opened on the outer wall of the counterweight sealing block, a connecting column is fixedly connected to the lower end of the counterweight sealing block, one end of the connecting column far away from the counterweight sealing block is fixedly connected with a sealing block, and a pressure relief door is rotatably connected to the inner wall of the sealing block.

[0012] Preferably, a condensation pipeline is fixedly connected to the inner wall of the water tank, an air inlet is opened at the connection between the water tank and the condensation pipeline, the air inlet is connected to the pressure pipe in a penetrating manner, a third water inlet is opened on the inner wall of the water tank, and the third water inlet is connected to the water pipe in a penetrating manner. When the air pressure in the tank body slowly increases, it will push the sealing block to move upward. While the sealing block moves upward, it drives the upper counterweight sealing block to move upward. A water groove is opened on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water groove will connect the second water inlet to the water tank. When the water tank is full of water, external water sources enter the water tank through the water groove, increasing the water pressure in the water tank and triggering the pressure nozzle connected to the water tank in a penetrating manner. The increased water pressure causes the pressure nozzle to spray water flows around. An outer shell is arranged around the pressure nozzle. When the water flow hits the inner wall of the outer shell, atomization occurs. After atomization, the water droplets re-aggregate and flow into the tank body from the holes. The water flow atomization process increases the efficiency of deoxidizing the hot steam. When the hot steam in the tank body is released through the air inlet, the pressure relief door will fall and close again due to the gravity at the upper end. Repeating this process keeps the water level in the tank body balanced; while pushing the sealing block to move upward, it drives the upper counterweight sealing block to move upward. A water groove is opened on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water groove will connect the second water inlet to the water tank, allowing external water flows to enter the water tank to supplement the water source pressure of the water tank. When the hot air flow is released through the pressure relief door, due to the release of air pressure, the counterweight sealing block moves downward due to its own weight, and at the same time drives the sealing block to move downward. The pressure relief door is blocked by the inner wall of the pressure pipe and the pressure relief door closes again. Repeating the above steps keeps the water tank full of water, adds water and pressurizes, and provides water sources for the tank body stage by stage.

[0013] Preferably, several heat dissipation copper sheets are fixedly connected to the middle section of the condensation pipeline. An exhaust pipe is fixedly connected to the outer wall of the condensation pipeline. A microporous waterproof and breathable cloth is fixedly connected to the inner wall of the exhaust pipe. A collection pipe is fixedly connected to the outer wall of the condensation pipeline. One end of the collection pipe far away from the condensation pipeline is fixedly connected to a U-shaped pipe. During operation, hot steam enters the second steam pipeline through the steam port. Several third steam pipelines are connected to the second steam pipeline. Several steam ports are opened on the several third steam pipelines. The hot steam enters the tank through the several steam ports. When the hot steam is discharged from the steam port, the oxygen carried out from the water in the tank. The pressure pipe is connected to the tank in a penetrating manner. When the hot steam finishes working and enters the pressure pipe, a sealing block is arranged in the pressure pipe. When the air pressure in the tank slowly increases, it will push the sealing block to move upward. When the sealing block moves upward to the air inlet, when the sealing block completely crosses the air inlet, the pressure relief door rotatably connected to the lower end of the sealing block will open towards the air inlet because it leaves the inner wall of the pressure pipe under the influence of gas pressure, so that the gas enters the exhaust recovery mechanism. When the gas enters the condensation pipeline, when the hot steam is being discharged, an exhaust pipe is connected through the outer wall of the condensation pipeline. When the hot steam condenses through the condensation pipeline, the water flowing in the water tank cools the hot steam in the condensation pipeline. At the same time, the hot steam also initially heats the water in the water tank, making the water in the water tank slowly rise. It not only condenses the condensable gas in the hot steam into water droplets and flows back into the tank, but also absorbs the heat of the hot steam to initially heat the water source in the water tank, accelerating the deoxidation efficiency of the next process.

[0014] Preferably, a collection pipe is fixedly connected to the outer wall of the condensation pipeline. An inlet is fixedly connected to the inner wall of the water tank. The inlet is connected to the water pipe in a penetrating manner. When the sealing block moves upward to the air inlet, when the sealing block completely crosses the air inlet, the pressure relief door rotatably connected to the lower end of the sealing block will open towards the air inlet because it leaves the inner wall of the pressure pipe under the influence of gas pressure, so that the gas enters the exhaust recovery mechanism. When the gas enters the condensation pipeline, the condensation pipeline is fixedly connected with heat dissipation copper sheets. The water in the water tank cools it, making the condensable gas in the gas condense into water droplets and enter the collection pipe. The lower end of the collection pipe is fixedly connected to a U-shaped pipe. The special pipeline of the U-shaped pipe can effectively prevent the passage of steam. The remaining non-condensable gas is discharged through the exhaust pipe. A microporous waterproof and breathable cloth is arranged in the exhaust pipe to prevent the loss of water and lock the condensed water droplets into the collection pipe. Through the above settings, the waste of water resources caused by the loss of water vapor formed during deoxidation can be effectively prevented.

[0015] A method for using a deaerator with an exhaust recovery function includes the following steps:

[0016] S1: Install pipelines: Before use, connect the water inlets and the second water inlet to the water source, install the pipelines for the steam port. An outlet is opened at the bottom of the tank. Install the corresponding pipelines for the outlet and ensure that all pipelines are connected smoothly;

[0017] S2: Start the device: First, add water to the water tank from the water inlet. When the water tank is kept full and the tank body is in a semi - full water state, close the water inlet and open the second water inlet, and then connect the steam port to inject hot steam.

[0018] The present invention has the following beneficial effects:

[0019] (1) Aiming at the problem of low exhaust gas recovery rate and a large amount of water carried away by hot steam in the present invention, an exhaust gas recovery mechanism and a heating mechanism are provided in the device. Before use, connect and install each pipeline and ensure that each pipeline is unobstructed. During operation, hot steam enters the second steam pipeline through the steam port. A number of third steam pipelines are connected to the second steam pipeline, and a number of steam ports are opened on the third steam pipelines. The hot steam enters the tank body through the number of steam ports. When the hot steam is discharged from the steam port, it will carry out oxygen from the water in the tank body and also vaporize some water molecules. The pressure pipe is connected to the tank body in a through - connection manner. When the air pressure in the tank body slowly increases, it will push the sealing block upward to the air inlet. When the sealing block crosses the air inlet, the pressure relief door rotatably connected to the lower end of the sealing block will open towards the air inlet because it leaves the inner wall of the pressure pipe under the influence of gas pressure, so that the gas enters the exhaust gas recovery mechanism. When the gas enters the condensation pipeline, the condensation pipeline is fixedly connected with heat - dissipating copper sheets, and the water in the water tank cools it, so that the condensable gas in the gas condenses into water droplets and enters the collection pipe. The lower end of the collection pipe is fixedly connected with a U - shaped pipe. When the U - shaped section of the U - shaped pipe is filled with condensed water, it can effectively prevent the passage of steam. The remaining non - condensable gas is discharged through the exhaust pipe. A microporous waterproof breathable cloth is provided in the exhaust pipe to prevent the loss of water and lock the condensed water droplets into the collection pipe. Through the above settings, it can effectively prevent the waste of water resources caused by the loss of water vapor formed during deoxidation.

[0020] (2) Utilizing the force of the above - mentioned steam to push the sealing block in the present invention, when the hot steam completes its work and enters the pressure pipe, a sealing block is provided in the pressure pipe. When the air pressure in the tank body slowly increases, it will push the sealing block upward. When the sealing block moves upward to the air inlet, when the sealing block crosses the air inlet, the pressure relief door rotatably connected to the lower end of the sealing block will open towards the air inlet because it leaves the inner wall of the pressure pipe under the influence of gas pressure, so that the gas enters the exhaust gas recovery mechanism. When the gas enters the condensation pipeline, during the process of discharging the hot steam, the outer wall of the condensation pipeline is connected with the exhaust pipe in a through - connection manner. The hot steam condenses through the condensation pipeline. While the flowing water in the water tank cools the hot steam in the condensation pipeline, the hot steam in turn preliminarily heats the water in the water tank, making the water temperature in the water tank slowly rise. It not only condenses the condensable gas in the hot steam into water droplets and flows back into the tank body, but also absorbs the heat of the hot steam to preliminarily heat the water source in the water tank, accelerating the deoxidation efficiency of the next process.

[0021] (3) The present invention utilizes the air pressure generated by the discharge of the above-mentioned hot steam to push the sealing block upward while driving the counterweight sealing block at the upper end upward. A water tank is provided on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water tank connects the second water inlet and the water tank, enabling external water flow to enter the water tank to supplement the water pressure source for the water tank. When the hot air flow is released through the pressure relief door, due to the release of air pressure, the counterweight sealing block moves downward due to its own weight, while driving the sealing block downward. The pressure relief door is blocked by the inner wall of the pressure pipe, causing the pressure relief door to close again. By repeating the above steps, the water tank is kept full of water, and water is added and pressurized, while providing water to the tank stage by stage to keep the water level in the tank balanced.

[0022] (4) The present invention utilizes the force of the above-mentioned hot steam. When the air pressure in the tank gradually increases, it will push the sealing block upward. While the sealing block moves upward, it drives the counterweight sealing block at the upper end upward. A water tank is provided on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water tank connects the second water inlet and the water tank. When the water tank is full of water, external water source enters the water tank through the water tank, increasing the water pressure in the water tank and triggering the pressure nozzle connected to the water tank through penetration. After the water pressure increases, the pressure nozzle sprays water flow in all directions. There is a housing around the pressure nozzle. When the water flow hits the inner wall of the housing, it is atomized. After atomization, it re-aggregates into water droplets and flows into the tank through the holes. When the water flow is atomized, the high-temperature steam fully heats it, increasing the deoxygenation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The tops of a plurality of support columns 41 are fixedly connected to a water tank 21, and a pressure pipe 43 is fixedly connected to the outer wall of the water tank 21.

[0043] One end of the pressure pipe 43 far from the water tank 21 is fixedly connected to the tank body 1. A counterweight seal block 45 is slidably connected to the inner wall of the pressure pipe 43. A water port 44 is provided at one end of the pressure pipe 43 close to the water tank 21, and the water port 44 is connected to the water tank 21 in a through manner.

While the sealing block 48 moves upward, it drives the counterweight sealing block 45 at the upper end to move upward. A water groove 46 is provided on the counterweight sealing block 45. When the counterweight sealing block 45 moves upward to a certain height, the water groove 46 will connect the second water inlet 23 with the water tank 21.

The atomization process of the water flow increases the efficiency of deaerating the hot steam. When the hot steam in the tank body 1 is released through the air inlet 51, the pressure relief door 49 will fall and close again due to the gravity at the upper end. Repeating this process keeps the water level in the tank body 1 balanced.

[0046] Embodiment 2. Please refer to Figure 6 - Figure 10 Based on Embodiment 1, the present invention is a deaerator with an exhaust gas recovery function and its usage method. While pushing the sealing block 48 to move upward, it drives the counterweight sealing block 45 at the upper end to move upward. A water groove 46 is provided on the counterweight sealing block 45. When the counterweight sealing block 45 moves upward to a certain height, the water groove 46 will connect the second water inlet 23 with the water tank 21, allowing external water flow to enter the water tank 21 to supplement the water pressure in the water tank 21. When the hot air flow is released through the pressure relief door 49, due to the release of air pressure, the counterweight sealing block 45 moves downward due to its own weight, and at the same time drives the sealing block 48 to move downward. The pressure relief door 49 is blocked by the inner wall of the pressure pipe 43 and thus closes again. Repeating the above steps keeps the water tank 21 full of water, adding water and pressurizing, and at the same time providing water source for the tank body 1 stage by stage.

[0047] In the middle section of the condensation pipe 52, a number of heat dissipation copper sheets 53 are fixedly connected. An exhaust pipe 54 is fixedly connected to the outer wall of the condensation pipe 52. A microporous waterproof and breathable cloth 57 is fixedly connected to the inner wall of the exhaust pipe 54. A collection pipe 55 is fixedly connected to the outer wall of the condensation pipe 52. One end of the collection pipe 55 far from the condensation pipe 52 is fixedly connected to a U-shaped pipe 58. During operation, hot steam enters the second steam pipe 32 through the steam port 14. A number of third steam pipes 33 are connected to the second steam pipe 32. A number of steam ports 34 are provided on the number of third steam pipes 33. The hot steam enters the tank 1 through the number of steam ports 34. When the hot steam is discharged from the steam port 34 and sprays upward from the bottom of the tank 1 for deaeration, the pressure pipe 43 is connected to the tank 1 in a penetrating manner. When the hot steam finishes working, it enters the pressure pipe 43. A sealing block 48 is provided in the pressure pipe 43. When the air pressure in the tank 1 slowly increases, it will push the sealing block 48 to move upward. When the sealing block 48 moves upward to the air inlet 51 and completely crosses the air inlet 51, the pressure relief door 49 rotatably connected to the lower end of the sealing block 48 will open towards the air inlet 51 because it leaves the inner wall of the pressure pipe 43 under the influence of gas pressure, so that the gas enters the exhaust recovery mechanism 2. When the gas enters the condensation pipe 52, when the hot steam is being discharged, the exhaust pipe 54 is connected through the outer wall of the condensation pipe 52. When the hot steam condenses through the condensation pipe 52, the water flowing in the water tank 21 cools the hot steam in the condensation pipe 52, and at the same time, the hot steam in turn preliminarily heats the water in the water tank 21, causing the water in the water tank 21 to slowly rise. It not only condenses the condensable gas in the hot steam into water droplets and flows back into the tank 1, but also absorbs the heat of the hot steam to preliminarily heat the water source in the water tank 21, accelerating the deaeration efficiency of the next process.

[0048] A collection pipe 55 is fixedly connected to the outer wall of the condensation pipe 52. An inlet 22 is fixedly connected to the inner wall of the water tank 21. The inlet 22 is connected through the water pipe 36. When the sealing block 48 moves upward to the air inlet 51 and completely crosses the air inlet 51, the pressure relief door 49 rotatably connected to the lower end of the sealing block 48 will open towards the air inlet 51 because it leaves the inner wall of the pressure pipe 43 under the influence of gas pressure, so that the gas enters the exhaust recovery mechanism 2. When the gas enters the condensation pipe 52, the condensation pipe 52 is fixedly connected with heat dissipation copper sheets 53. The water in the water tank cools it, causing the condensable gas in the gas to condense into water droplets and enter the collection pipe 55. The lower end of the collection pipe 55 is fixedly connected to a U-shaped pipe 58. The special pipe of the U-shaped pipe 58 can effectively prevent the passage of steam. The remaining non-condensable gas is discharged through the exhaust pipe 54. A microporous waterproof and breathable cloth 57 is provided in the exhaust pipe 54 to prevent the loss of water and lock the condensed water droplets into the collection pipe 55. Through the above settings, the waste of water resources caused by the loss of water vapor formed during deaeration can be effectively prevented.

[0049] A method for using a deaerator with an exhaust gas recovery function, comprising the following steps:

[0050] S1: Install pipelines: Before use, connect the water inlet 22 and the second water inlet 23 to the water source, install pipelines for the steam port 14, a water outlet 15 is provided at the bottom of the tank body 1, install corresponding pipelines for the water outlet 15, and ensure that all pipelines are connected smoothly;

[0051] S2: Start the equipment: First, add water to the water tank 21 from the water inlet 22. When the water tank 21 is kept full and the tank body 1 is in a semi-full water state, close the water inlet 22, open the second water inlet 23, and then connect the steam port 14 to inject hot steam.

[0052] A specific application of this embodiment is: To address the problem of low exhaust gas recovery rate, an exhaust gas recovery mechanism 2 and a heating mechanism 3 are provided in this equipment. Before use, connect and install all pipelines and ensure that all pipelines are unobstructed, fill the water tank 21 with water, and fill the tank body with semi-full water. During operation, hot steam enters the second steam pipeline 32 through the steam port 14. A number of third steam pipelines 33 are connected to the second steam pipeline 32, and a number of steam ports 34 are provided on the number of third steam pipelines 33. The hot steam enters the tank body 1 through the number of steam ports 34. When the hot steam is discharged from the steam port 34, the oxygen carried out from the water in the tank body 1, the pressure pipe 43 is connected to the tank body 1 in a through manner. When the hot steam completes its work and enters the pressure pipe 43, a sealing block 48 is provided in the pressure pipe 43. When the sealing block 48 moves upward to the air inlet 51, when the sealing block 48 completely crosses the air inlet 51, the pressure relief door 49 rotatably connected to the lower end of the sealing block 48 will open towards the air inlet 51 because it leaves the inner wall of the pressure pipe 43 under the influence of gas pressure, so that the gas enters the exhaust gas recovery mechanism 2. When the gas enters the condensation pipeline 52, the condensation pipeline 52 is fixedly connected with a heat dissipation copper sheet 53, and the water in the water tank cools it, so that the condensable gas in the gas condenses into water droplets and enters the collection pipe 55. The lower end of the collection pipe 55 is fixedly connected with a U-shaped pipe 58. The special pipeline of the U-shaped pipe 58 can effectively prevent the passage of steam. The remaining non-condensable gas is discharged through the exhaust pipe 54. A microporous waterproof breathable cloth 57 is provided in the exhaust pipe 54 to prevent the loss of water and lock the condensed water droplets into the collection pipe 55. Through the above settings, it is possible to effectively prevent the waste of water resources caused by the loss of water vapor formed during the deaeration process.

[0053] By utilizing the force of the steam to push the sealing block 48, when the sealing block 48 moves upward to the air inlet 51, when the sealing block 48 completely passes over the air inlet 51, the pressure relief valve 49 rotatably connected to the lower end of the sealing block 48 will leave the inner wall of the pressure tube 43, and under the influence of the gas pressure, it will open to the air inlet 51, so that the gas enters the exhaust recovery mechanism 2. After the gas enters the condensation pipe 52, when the hot steam is in the process of being discharged, the outer wall of the condensation pipe 52 is penetrated and connected with an exhaust pipe 54. When the hot steam condenses through the condensation pipe 52, the water flowing in the water tank 21 cools the hot steam in the condensation pipe 52, and the hot steam in turn preliminarily heats the water in the water tank 21, so that the water in the water tank 21 slowly rises, not only condensing the condensable gas in the hot steam into water droplets that flow back to the tank body 1, but also absorbing the heat of the hot steam to preliminarily heat the water source in the water tank 21, thereby accelerating the deoxygenation efficiency of the next process.

[0054] The air pressure generated by the above-mentioned hot steam discharge is used to push the sealing block 48 to move upward while driving the upper counterweight sealing block 45 to move upward. A water trough 46 is provided on the counterweight sealing block 45. When the counterweight sealing block 45 moves upward to a certain height, the water trough 46 connects the water inlet 23 with the water tank 21, allowing external water to flow into the water tank 21 to replenish the water pressure of the water source for the water tank 21. When the hot air flow is released through the pressure relief valve 49, due to the release of air pressure, the counterweight sealing block 45 moves downward due to its own weight, and at the same time drives the sealing block 48 to move downward. The pressure relief valve 49 is blocked by the inner wall of the pressure tube 43, so that the pressure relief valve 49 is closed again. The above steps are repeated to keep the water tank 21 full of water, add water and pressurize it, and at the same time provide water to the tank body 1 intermittently to keep the water level of the tank body 1 balanced.

[0055] By utilizing the force of the hot steam, when the air pressure in the tank body 1 gradually increases, the sealing block 48 is pushed upward, and the sealing block 48 moves upward while driving the counterweight sealing block 45 at the upper end to move upward. The counterweight sealing block 45 is provided with a water tank 46. When the counterweight sealing block 45 moves upward to a certain height, the water tank 46 connects the water inlet 23 with the water tank 21. When the water tank 21 is full of water, the external water source enters the water tank 21 through the water tank 46, so that the water pressure in the water tank 21 increases, triggering the connection with the water tank 21. 21 penetrates and connects the pressure nozzle 37. When the water pressure increases, the pressure nozzle 37 sprays water in all directions. A shell 35 is arranged around the pressure nozzle 37. When the water hits the inner wall of the shell 35, it is atomized. After atomization, it re-aggregates into water droplets and flows from the hole 38 to the tank body 1. The water atomization process increases the efficiency of hot steam deoxygenation. When the hot steam in the tank body 1 is released through the air inlet 51, the pressure relief door 49 will fall down and close again at the upper end due to gravity. This process is repeated to keep the water level in the tank body 1 balanced.
