Description

Technical Field

[0001] The invention relates to the field of HVAC systems, and in particular to a device for deoxygenating incoming water in HVAC systems. Background Art

[0002] The HVAC system refers to the heating, gas supply, ventilation and air-conditioning engineering, which is an important part of the building. It aims to provide people with a comfortable, safe and energy-saving indoor environment. The working principle of the HVAC system is mainly based on a series of heat transfer, heat exchange and heat transmission processes. By controlling the temperature, flow and humidity of the air and other parameters, a comfortable environment is created for the room. Before adding water to the existing HVAC system, it is necessary to remove oxygen from the water source to prevent high-temperature water carrying oxygen from entering the pipe system, causing oxidation inside the pipe, thereby reducing the service life of the pipe.

[0003] The Chinese invention patent application with announcement number CN212987181U is a water replenishment and deoxygenation device for a new energy boiler, including a water supply tank, a booster pump is fixedly installed on the top surface of the water supply tank, and one end of the booster pump is connected to an air intake pipe, and the other end of the booster pump is connected to a U-shaped tube; in the utility model, the booster pump is turned on by the control panel, prompting the air intake pipe to guide the water vapor in the boiler into the U-shaped tube, and then discharged into the two comb-tooth type air injection pipes on the inner side of the water supply tank, so that the water vapor is discharged into the water supply tank through multiple air holes on the surface of the two air injection pipes, which is beneficial to the heat exchange between the water vapor and the liquid in the water supply tank, and can also disturb the liquid in the water tank in the form of bubbles. At the same time, the water vapor can increase the air pressure in the water supply tank, which is beneficial to the increase of the temperature in the water supply tank. By turning on the electric heating tube through the control panel, the double heating of the liquid in the water supply tank can be achieved, which is beneficial to the rapid increase of the temperature in the water supply tank, thereby increasing the deoxygenation efficiency.

[0004] During use, existing deoxygenation devices generally use high-temperature deoxygenation to separate oxygen. During separation, water vapor needs to be condensed to separate oxygen and other gases and water in the water source. However, the disadvantage of this method is that the water is at a relatively low temperature after separation. At this time, it takes a lot of resources to heat it when it is added to the HVAC system so that it is heated to the temperature required by the HVAC system. In addition, when water is added to the deoxygenation device, it also takes a lot of resources to heat it to an evaporating state, which greatly increases the cost of deoxygenation.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The present invention provides Figure 1-8 A device for deoxygenating water entering a HVAC system is shown, comprising a deoxygenation tank 001, a support leg 101 is installed below the deoxygenation tank 001, a partition 102 is installed on the inner wall of the deoxygenation tank 001, and the partition 102 divides the deoxygenation tank 001 into two upper and lower spaces, a pressure relief port 103 is opened on the inner wall of the deoxygenation tank 001, a heating pipe 104 is connected through the bottom of the deoxygenation tank 001, a water injection pipe 105 is installed at the bottom of the deoxygenation tank 001, and the water injection pipe 105, the heating pipe 104 and the pressure relief port 103 are all arranged in the space below the deoxygenation tank 001;

[0034] Water can be injected into the space below the deaerator tank 001 through the water injection pipe 105, and the heating pipe 104 can inject heat to heat the water. When the pressure is high, the pressure relief port 103 can be opened to relieve the pressure in the deaerator tank 001 to ensure safe deoxygenation.

[0035] The deoxygenation component 002 is disposed above the deoxygenation tank 001 and is used to remove oxygen from the water;

[0036] The stirring assembly 003 is disposed at the lower part of the deaerator tank 001 and is used to stir the water source;

[0037] The flow guide component 004 is arranged below the partition 102 and is used for guiding the steam.

[0038] Furthermore, in the above structure, the deoxygenation component 002 includes a through hole 201, which is opened in the partition 102 and is arranged in a ring-shaped distribution. A steam pipe 202 is connected through the through hole 201, and the steam pipe 202 is arranged in the upper space inside the deoxygenation tank 001. A connecting pipe 203 is connected through one side of the steam pipe 202 in a ring-shaped distribution, and the connecting pipe 203 is connected to the remaining corresponding through holes 201, and this structure is arranged in a ring-shaped distribution on the partition 102.

[0039] The steam in the space below the deaerator tank 001 can enter the steam pipe 202 and the connecting pipe 203 through the through hole 201 .

[0040] Furthermore, in the above structure, a condenser 211 is installed on the top of the deoxygenation tank 001, an annular condenser tube 212 is installed above the partition 102, and the annular condenser tube 212 is connected to the condenser 211 pipeline, a U-shaped tube 204 is connected through the top of the steam pipe 202, and the annular condenser tube 212 is penetrated and fitted with the turning parts of each group of U-shaped tubes 204.

[0041] Through the condenser 211, the annular condenser tube 212 can perform condensation work at the turning point of the U-shaped tube 204. At this time, the steam passing through the U-shaped tube 204 will be liquefied due to the condensation, and the internal gas will continue to be transported along the U-shaped tube 204, thereby completing the oxygen removal work in the water source.

[0042] Furthermore, in the above structure, an L-shaped drain pipe 205 is connected through the lowest point of the U-shaped pipe 204, and the L-shaped drain pipe 205 penetrates the partition 102, and the L-shaped drain pipe 205 is connected through the interior of the lower space inside the deaerator tank 001. An annular pipe 206 is installed below the outer side of the deaerator tank 001, and the annular pipe 206 is connected through each group of L-shaped drain pipes 205, and a drain pipe 210 is connected through one side of the annular pipe 206.

[0043] The condensed and liquefied water source can be collected through the L-shaped drain pipe 205 and transported through the lower space inside the deaerator tank 001. At this time, due to the high-temperature water source in the space below the deaerator tank 001, the liquefied water source can be heated to increase its temperature or return to normal temperature to avoid its low temperature after deoxygenation. Finally, it enters the annular pipe 206 and is transported to the heating system by the drain pipe 210.

[0044] Furthermore, in the above structure, a second annular pipe 207 is installed above the outer side of the deaerator tank 001, and the second annular pipe 207 is connected with each group of U-shaped pipes 204, and one side of the second annular pipe 207 is connected with the exhaust gas recovery device pipeline, a spiral pipe 208 is installed in the space below the deaerator tank 001, a guide pipe 209 is installed between the spiral pipe 208 and the second annular pipe 207, and a control valve is installed in the guide pipe 209, and the spiral pipe 208 and the L-shaped drain pipe 205 are immersed in the water source in the space below the deaerator tank 001.

[0045] The gas can be transported to the annular pipe 207 through the U-shaped pipe 204. At this time, since the gas in the annular pipe 207 still has a certain temperature, when new water is injected under the deaerator tank 001, the temperature is relatively low, and the gas can be transported to the spiral pipe 208 to heat the newly injected water. When heated to a higher temperature, the guide pipe 209 can be closed so that the gas can be discharged normally.

[0046] Furthermore, in the above structure, the stirring assembly 003 includes a motor 301, which is installed above the partition 102 and located in the space above the deaerator tank 001. A main stirring rod 302 is installed at the output end of the motor 301, and the main stirring rod 302 is arranged in the space below the deaerator tank 001.

[0047] The motor 301 can drive the main stirring rod 302 to rotate in the space below the deaerator tank 001, thereby stirring the water source and increasing the efficiency of water source heating.

[0048] Furthermore, in the above structure, an annular frame 303 is installed above the main stirring rod 302 , a main draft tube 304 is installed below the partition 102 , and the interior of the main draft tube 304 completely covers all the through holes 201 .

[0049] The main flow tube 304 allows the water vapor generated by the water source to smoothly enter the area where the through hole 201 is located.

[0050] Furthermore, in the above structure, a gear ring 305 is installed on the inner wall of the main flow tube 304, four groups of auxiliary stirring rods 306 are rotatably connected below the annular frame 303, a gear ring 2 404 is installed above the annular frame 303, gears 307 are sleeved and fixed on the four groups of auxiliary stirring rods 306, and the four groups of gears 307 are meshed with the gear ring 305.

[0051] The gear 1 307 slides along the gear ring 2 404 , so that the auxiliary stirring rod 306 can rotate as a whole under the action of the annular frame 303 and can rotate on its own, thereby improving the stirring effect.

[0052] Furthermore, in the above structure, the guide assembly 004 includes an auxiliary guide tube 401, which is installed in a ring-shaped distribution below the partition 102, and the auxiliary guide tube 401 covers each group of through holes 201 separately. A turbofan 402 is installed in the auxiliary guide tube 401, and a gear 2 403 is connected to the axis below the turbofan 402, and each group of gear 2 403 is meshed with a gear ring 2 404.

[0053] By setting the auxiliary guide tube 401, the gear ring 2 404 can drive the turbofan 402 to rotate under the action of the annular frame 303, so that water vapor enters the auxiliary guide tube 401, thereby accurately delivering the water vapor into the through hole 201 and improving the efficiency of water vapor transportation.

[0054] like Figure 1-8As shown, water can be injected into the space below the deaerator tank 001 through the water injection pipe 105. At this time, the heating pipe 104 heats the water source. At the same time, the motor 301 drives the main stirring rod 302 and the auxiliary stirring rod 306 to rotate, thereby stirring the water source to increase the heating efficiency. At the same time, the turbofan 402 rotates in the auxiliary guide tube 401 to guide the water vapor generated by the water source, so that the water vapor enters the steam pipe 202 and the connecting pipe 203 through the through hole 201. When passing through the bend of the U-shaped pipe 204, the water vapor is condensed into water under the condensation effect of the annular condenser 212, and enters the annular pipe 206 through the L-shaped drain pipe 205. At the same time, the deoxygenated Air will be continuously transported to the annular pipe 207, and when the temperature of the water source below the deaerator tank 001 is low, the residual heat of the deoxygenated air can be transferred to the water source below the deaerator tank 001 through the spiral tube 208. Otherwise, it will be discharged normally to realize heat energy recovery and reduce the cost of deoxygenation. The water in the L-shaped drain pipe 205 will pass through the water source in the space below the deaerator tank 001, thereby preheating the water in the L-shaped drain pipe 205 so that it can quickly heat up when it enters the HVAC system, thereby reducing resources. This structure can ensure that the deoxygenated water source can quickly reach the water temperature required by the HVAC system, reduce the power consumption of HVAC heating and deoxygenation heating, and achieve the purpose of saving resources.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
