Description

Technical Field

[0001] The invention relates to the technical field of deaerator equipment, and in particular to a deaerator with an exhaust steam recovery function and a use method thereof. Background Art

[0002] With the continuous development and improvement of production technology, the specifications and types of deaerators are also constantly developing and improving. Among them, the spray deaerator has been widely used in many fields due to its excellent properties and other characteristics. The deaerator achieves efficient deoxygenation through the new structure. However, during the use of the deaerator, the heating steam used in the deaerator is discharged through the exhaust pipe. Directly discharging the steam is not only likely to affect the environment near the equipment, but also likely to increase energy loss. The deaerator is not convenient for timely recovery and treatment of the discharged steam, and it cannot be recycled, resulting in increased equipment use costs.

[0003] Therefore, some models of spray deaerators are set up here to solve the problem of not being able to recycle steam. When the machine is working, part of the water in the hot steam evaporates during the deoxygenation process and merges with the hot steam and is discharged, which not only causes the loss of water resources, but also the heat of the hot steam is not fully utilized, causing the machine to waste resources and increase the cost of use.

When the air pressure in the tank body slowly increases, the sealing block will be pushed to move upward, and the sealing block will drive the upper counterweight sealing block to move upward at the same time. A water trough is provided on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water trough will connect the water inlet two with the water tank. When the water tank is full of water, an external water source enters the water tank through the water trough, so that the water pressure in the water tank becomes larger, triggering a pressure nozzle connected through the water tank. The increased water pressure causes the pressure nozzle to spray water to the surroundings. A shell is provided around the pressure nozzle. When the water hits the inner wall of the shell, atomization is generated, and the atomization is re-aggregated into water droplets.

The pressure pipe is connected to the tank body, and enters the pressure pipe after the hot steam completes its work. A sealing block is provided in the pressure pipe, and when the air pressure in the tank body slowly increases, the sealing block is pushed upward Move, when the sealing block moves upward to the air inlet, when the sealing block completely passes the air inlet, the pressure relief valve connected to the lower end of the sealing block will leave the inner wall of the pressure tube, and under the influence of the gas pressure, it will open to the air inlet, so that the gas enters the exhaust recovery mechanism. After the gas enters the condensation pipe, when the hot steam is in the process of being discharged, the outer wall of the condensation pipe is penetrated and connected with an exhaust pipe. When the hot steam condenses through the condensation pipe, the water flowing in the water tank cools the hot steam in the condensation pipe. At the same time, the hot steam in turn preliminarily heats the water in the water tank, so that the water in the water tank slowly rises, not only condensing the condensable gas in the hot steam into water droplets and flowing back to the tank body, but also absorbing the heat of the hot steam to preliminarily heat the water source in the water tank, thereby accelerating the deoxygenation efficiency of the next process.

[0012] Preferably, a collecting pipe is fixedly connected to the outer wall of the condensation pipe, a water inlet is fixedly connected to the inner wall of the water tank, and the water inlet is through-connected to the water pipe. When the sealing block moves upward to the air inlet, when the sealing block completely passes over the air inlet, the pressure relief valve rotatably connected to the lower end of the sealing block will leave the inner wall of the pressure pipe and, under the influence of the gas pressure, open to the air inlet, thereby allowing the gas to enter the exhaust recovery mechanism. After the gas enters the condensation pipe, the condensation pipe is fixedly connected to a heat dissipation copper sheet, and the water in the water tank cools it, so that the condensable gas in the gas condenses into water droplets and enters the collecting pipe. A U-shaped pipe is fixedly connected to the lower end of the collecting pipe. The special pipe of the U-shaped pipe can effectively prevent the passage of steam, and the remaining non-condensable gases are discharged through the exhaust pipe. A microporous waterproof and breathable cloth is provided in the exhaust pipe to prevent the loss of water and lock the condensed water droplets into the collecting pipe. The above-mentioned arrangement can effectively prevent the waste of water resources caused by the loss of water vapor formed during the deoxygenation process.

[0014] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem that the exhaust gas recovery rate is low and the hot steam carries away a large amount of water. An exhaust gas recovery mechanism and a heating mechanism are arranged in the device. Before use, the various pipelines are connected and installed to ensure that the pipelines are unobstructed. During operation, the hot steam enters the steam pipe 2 through the steam port. The steam pipe 2 is connected to a plurality of steam pipes 3, and a plurality of steam ports are provided on the plurality of steam pipes 3. The hot steam enters the tank body through the plurality of steam ports. When the hot steam is discharged from the steam port, it takes out oxygen from the water in the tank body and also vaporizes some water molecules. The pressure pipe is connected to the tank body. When the air pressure in the tank body gradually increases, it pushes the sealing block to move upward to the air inlet. When the sealing block passes over the air inlet, the lower end of the sealing block rotates and is connected The connected pressure relief valve will leave the inner wall of the pressure pipe, and under the influence of gas pressure, it will open to the air inlet, so that the gas enters the exhaust recovery mechanism. After the gas enters the condensation pipe, the condensation pipe is fixedly connected with a heat dissipation copper sheet, and the water in the water tank cools it down, so that the condensable gas in the gas condenses into water droplets and enters the collecting pipe. The lower end of the collecting pipe is fixedly connected with a U-shaped tube. When the condensed water fills the U-shaped section of the U-shaped tube, it can effectively prevent the passage of steam, and the remaining non-condensable gases are discharged through the exhaust pipe. The exhaust pipe is provided with a microporous waterproof and breathable cloth to prevent water loss and lock the condensed water droplets into the collecting pipe. The above-mentioned arrangement can effectively prevent the waste of water resources caused by the loss of water vapor formed in the deoxygenation process.

[0015] (2) The present invention utilizes the force of the steam to push the sealing block. When the hot steam completes its work, it enters the pressure pipe. A sealing block is provided in the pressure pipe. When the air pressure in the tank body increases slowly, the sealing block is pushed to move upward. When the sealing block moves upward to the air inlet, when the sealing block passes over the air inlet, the pressure relief door connected to the lower end of the sealing block will leave the inner wall of the pressure pipe. Under the influence of the gas pressure, it will open toward the air inlet, thereby allowing the gas to enter the exhaust recovery mechanism. After the gas enters the condensation pipe, when the hot steam is being discharged, an exhaust pipe is connected to the outer wall of the condensation pipe. The hot steam condenses through the condensation pipe. While the water flowing in the water tank cools the hot steam in the condensation pipe, the hot steam in turn preliminarily heats the water in the water tank, causing the water temperature in the water tank to slowly increase. Not only does the condensable gas in the hot steam condense into water droplets and flow back to the tank body, but the heat of the hot steam is also absorbed to preliminarily heat the water source in the water tank, thereby accelerating the deoxygenation efficiency of the next process.

[0016] (3) The present invention utilizes the air pressure generated by the above-mentioned hot steam discharge to push the sealing block upward while driving the upper counterweight sealing block upward. A water trough is provided on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water trough connects the water inlet 2 with the water tank, allowing external water to flow into the water tank to replenish the water pressure of the water tank. When the hot air flow is released through the pressure relief valve, 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 downward. The pressure relief valve is blocked by the inner wall of the pressure pipe and its pressure relief valve is closed again. The above steps are repeated to keep the water tank full of water, add water and pressurize it, and at the same time provide water source for the tank body in stages to keep the water level of the tank body balanced.

[0017] (4) The present invention utilizes the force of the above-mentioned hot steam. When the air pressure in the tank body increases slowly, it will push the sealing block to move upward. When the sealing block moves upward, it will also drive the counterweight sealing block at the upper end to move upward. A water trough is provided on the counterweight sealing block. When the counterweight sealing block moves upward to a certain height, the water trough will connect the water inlet 2 with the water tank. When the water tank is full of water, the external water source enters the water tank through the water trough, increasing the water pressure in the water tank and triggering the pressure nozzle connected to the water tank. When the water pressure increases, the pressure nozzle sprays water in all directions. An outer shell is provided around the pressure nozzle. When the water hits the inner wall of the outer shell, it is atomized. After atomization, it re-aggregates into water droplets and flows from the hole to the tank body. When the water is atomized, the high-temperature steam fully heats it to increase its deoxygenation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] 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.

[0035] 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.

[0036] 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.
