Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically a medium-temperature waste heat heating device. Background Technology

[0002] Heating refers to supplying heat to buildings to maintain a certain indoor temperature. It is a social service that addresses the basic living needs of residents in northern my country for winter heating. Currently, hot water is delivered to residents' homes via boilers or underfloor heating systems.

[0003] However, existing heating systems use direct combustion in boilers for heating, which generates a large amount of medium- and high-temperature flue gas. Direct filtration and emission of this flue gas leads to a significant waste of thermal energy resources, which is detrimental to the environmentally friendly use of energy.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a medium-temperature waste heat heating device. Utility Model Content

[0005] The purpose of this invention is to provide a medium-temperature waste heat supply device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medium-temperature waste heat heating device, comprising a water tank, a water injection valve pipe fixedly connected to the upper left side of the outer surface of the water tank, a high-temperature pipe provided inside the water tank, the high-temperature pipe including an air inlet pipe fixedly connected through the left side of the water tank surface and connected to the exhaust end of a combustion boiler, a spiral pipe fixedly connected to the right end of the air inlet pipe inside the water tank, a discharge pipe fixedly connected to the right end of the spiral pipe, the right end of the discharge pipe penetrating the water tank, and a drain pipe fixedly connected to the upper right side of the outer surface of the water tank.

[0007] Preferably, the right end of both the drain pipe and the discharge pipe is fixedly connected to a tee connector, and the front and rear ends of the tee connector are fixedly connected to branch pipes.

[0008] Preferably, medium-temperature pipes are evenly distributed and fixedly connected to the right side of the surface of the right branch pipe of the discharge pipe, and a guide tube is fixedly sleeved on the surface of the medium-temperature pipe.

[0009] Preferably, the medium-temperature pipe and the guide tube extend to the corresponding household inlet, and the medium-temperature pipes in the same area are connected to the same flue gas guide pipe for drainage when they reach the household inlet.

[0010] Preferably, a solenoid valve tube is fixedly connected to the left side of the upper surface of the guide tube, and the left end of the solenoid valve tube is connected to the branch pipe on the right side of the drain pipe.

[0011] Preferably, a water supply pipe is fixedly connected to the right side of the upper surface of the guide tube, and the water supply pipe is connected to the corresponding household inlet pipe.

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

[0013] 1. This utility model, through the arrangement of a water tank, a water injection valve pipe, a high-temperature pipe, an air inlet pipe, a spiral pipe, and a discharge pipe, uses the water injection valve pipe to add water required for heating into the water tank. When the boiler is burning, a large amount of high-temperature flue gas is generated. The high-temperature flue gas enters the spiral pipe through the air inlet pipe. The spiral pipe is located inside the water tank and can contact the heating water, thereby using the high temperature of the flue gas to heat the heating water. At the same time, the spiral pipe increases the flow of the high-temperature flue gas, thereby improving the utilization rate of the high-temperature flue gas and enabling the high-temperature flue gas to heat the heating water more fully. However, after heating the heating water, the high-temperature flue gas still has a certain temperature and will be converted into medium-temperature waste heat flue gas, which is discharged from the water tank through the discharge pipe. This fully utilizes the high-temperature flue gas and avoids the waste caused by the direct discharge of waste heat from the flue gas, thus greatly improving the utilization rate of thermal energy resources.

[0014] 2. This utility model, through the arrangement of a T-joint, branch pipe, medium-temperature pipe, guide tube, solenoid valve pipe, and water supply pipe, allows medium-temperature flue gas to enter the lower branch pipe via the lower T-joint. The lower branch pipe then distributes the medium-temperature flue gas to various medium-temperature pipes. When residents require heating, the corresponding solenoid valve pipe is opened for different households. At this time, the heated heating water in the water tank will enter the upper branch pipe through the upper T-joint via the discharge pipe. The heating water in the upper branch pipe will then enter the corresponding guide tube through the corresponding opened solenoid valve pipe, flow through the guide tube, and finally... The water flows through the delivery pipes into the corresponding households for heating. However, when the heating water is flowing inside the guide tube, the residual heat released by the medium-temperature flue gas inside the medium-temperature pipe can keep the heating water warm. This prevents the heating water from weakening due to long-distance flow in the guide tube and failing to provide sufficient heating after entering the households. Utilizing the medium-temperature residual heat of the flue gas to keep the circulating heating water warm not only makes full use of the heat-carrying flue gas, but also eliminates the need for insulation materials on the pipes, greatly improving the utilization rate of heat energy resources while reducing the cost of auxiliary materials for equipment.

[0019] 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.

[0020] like Figures 1-3 As shown, a medium-temperature waste heat heating device includes a water tank 1. A water injection valve pipe 2 is fixedly connected to the upper left side of the outer surface of the water tank 1. A high-temperature pipe 3 is installed inside the water tank 1. The high-temperature pipe 3 includes an air inlet pipe 301 that is fixedly connected through the left side of the surface of the water tank 1 and is connected to the exhaust end of the combustion boiler. A spiral pipe 302 is fixedly connected to the right end of the air inlet pipe 301 inside the water tank 1. A discharge pipe 303 is fixedly connected to the right end of the spiral pipe 302. The right end of the discharge pipe 303 passes through the water tank 1. A drain pipe 4 is fixedly connected to the upper right side of the outer surface of the water tank 1.

[0021] By adopting the above technical solution, water required for heating is added to the inside of water tank 1 using water injection valve pipe 2.

[0022] When the boiler is burning, a large amount of high-temperature flue gas is generated. The high-temperature flue gas enters the spiral tube 302 through the air inlet pipe 301. The spiral tube 302 is located inside the water tank 1 and can contact the heating water. The high temperature of the flue gas is used to heat the heating water. At the same time, the spiral tube 302 increases the flow of the high-temperature flue gas, thereby improving the utilization rate of the high-temperature flue gas and enabling the high-temperature flue gas to heat the heating water more fully.

[0023] After the high-temperature flue gas heats the heating water, it still retains a certain temperature and will be converted into medium-temperature waste heat flue gas, which will be discharged from the water tank 1 through the discharge pipe 303.

[0024] Furthermore, a tee connector 5 is fixedly connected to the right end of both the drain pipe 4 and the discharge pipe 303, and a branch pipe 6 is fixedly connected to both the front and rear ends of the tee connector 5.

[0025] By adopting the above technical solution, the medium-temperature flue gas enters the lower branch pipe 6 through the lower three-way connector 5;

[0026] The heated water in water tank 1 will pass through drain pipe 303 and enter the upper branch pipe 6 via the upper tee connector 5.

[0027] Furthermore, medium-temperature pipes 7 are evenly distributed and fixedly connected to the right side of the surface of the right branch pipe 6 of the discharge pipe 303, and a guide tube 8 is fixedly sleeved on the surface of the medium-temperature pipe 7.

[0028] By adopting the above technical solution, the lower branch pipe 6 will distribute the medium-temperature flue gas to each medium-temperature pipe 7.

[0029] Furthermore, the medium-temperature pipe 7 and the guide tube 8 extend all the way to the corresponding household inlet for heating, and the medium-temperature pipe 7 in the same area connects to the same flue gas guide pipe for diversion and discharge when it reaches the household inlet.

[0030] A solenoid valve tube 9 is fixedly connected to the left side of the upper surface of the guide tube 8, and the left end of the solenoid valve tube 9 is connected to the branch pipe 6 on the right side of the drain pipe 4.

[0031] A water supply pipe 10 is fixedly connected to the right side of the upper surface of the guide tube 8, and the water supply pipe 10 is connected to the corresponding inlet pipe.

[0032] By adopting the above technical solution, when residents need heating, the corresponding solenoid valve pipe 9 is opened for different households. At this time, the heated heating water in the water tank 1 will enter the upper branch pipe 6 through the discharge pipe 303 via the upper tee connector 5. The heating water in the upper branch pipe 6 will enter the corresponding guide tube 8 through the corresponding opened solenoid valve pipe 9. After flowing through the guide tube 8, it will finally enter the corresponding household's home for heating through the water supply pipe 10.

[0033] When the heating water flows inside the guide tube 8, the residual heat released by the medium-temperature flue gas inside the medium-temperature pipe 7 can keep the heating water warm, thus preventing the heating water from weakening due to long-distance flow in the guide tube 8 and failing to provide sufficient heating after entering the residents' homes.

[0034] Working Principle: When using this medium-temperature waste heat heating device, firstly, the water required for heating is added to the water tank 1 through the water injection valve pipe 2. During boiler combustion, a large amount of high-temperature flue gas is generated. The high-temperature flue gas enters the spiral tube 302 through the air inlet pipe 301. The spiral tube 302 is located inside the water tank 1 and can contact the heating water, thereby using the high temperature of the flue gas to heat the heating water. At the same time, the spiral tube 302 increases the flow of the high-temperature flue gas, thereby improving the utilization rate of the high-temperature flue gas and enabling the high-temperature flue gas to heat the heating water more fully. However, after heating the heating water, the high-temperature flue gas still has a certain temperature and will be converted into medium-temperature waste heat flue gas, which is discharged from the water tank 1 through the discharge pipe 303. The medium-temperature flue gas enters the lower branch pipe 6 through the lower tee connector 5. The lower branch pipe 6 distributes the medium-temperature flue gas to each medium-temperature pipe 7. When residents need heating, they open the corresponding solenoid valve pipe 9 for different households. At this time, the heated heating water in the water tank 1 will enter the upper branch pipe 6 through the discharge pipe 303 via the upper tee connector 5. The heating water in the upper branch pipe 6 will enter the corresponding guide cylinder 8 through the corresponding opened solenoid valve pipe 9. After flowing through the guide cylinder 8, it will finally enter the corresponding household through the water supply pipe 10 for heating. However, when the heating water is flowing inside the guide cylinder 8, the residual heat released by the medium-temperature flue gas inside the medium-temperature pipe 7 can keep the heating water warm, ensuring that the heating water always has heat to enter the household for heating. This is the working principle of the medium-temperature waste heat heating device.
