Gas-fired boilers are the most economical compared to oil-fired boilers and electric boilers, so most people choose gas-fired boilers as boiler equipment for steam, heating, and bathing, for heating residential or regional areas.

[0003] The water vapor generated by the existing gas boiler during operation will be directly discharged as the pressure increases. Since the water vapor contains water, a large amount of water in the boiler will be taken away with the discharge of the water vapor. Therefore, a large amount of water needs to be added to the boiler, which wastes water resources. At the same time, the condensed liquid during the subsequent transportation of the water vapor will cause corrosion to the subsequent heating pipeline. Therefore, based on the above problems, an energy-saving gas boiler is proposed. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, by setting the structures such as the boiler body, the transfer part, the heat exchange part and the separation module, a large amount of water vapor will be generated after the boiler body heats the internal water. As the water vapor increases, the furnace pressure will increase accordingly. When it increases to a certain value, the pressure gauge will send an electrical signal to the control box, so that the control box controls the connecting valve pipe of the transfer part to open, so that the water vapor in the boiler body flows into the box body of the transfer part through the connecting valve pipe, and pushes up the piston plate, so that the water vapor enters the heat exchange part through the gas transmission valve pipe, and then enters the separation module through the heat exchange part. When passing through the heat exchange tube, the high-temperature water vapor will cooperate with the high-temperature flue gas in the first return smoke pipe and the second return smoke pipe to assist in heating the newly added water, so that the burner can quickly heat the newly added water through a low-power small fire, and the separation module can The incoming water vapor is separated into steam and water, and the separated water flows back into the cylinder through the drain valve pipe, reducing the amount of new water that needs to be added to the water pump mechanism, thereby saving the use of water resources. The separated hot air flow can be connected to the heating pipe for heating a residence or a certain area. The high-temperature water vapor generated during the operation of the energy-saving gas boiler can cooperate with the high-temperature flue gas in the smoke pipe to assist in heating the new water, so that the burner can quickly heat the new water at a lower power. The water vapor can be separated into steam and water so that the separated water can be recycled to save the use of water resources. This solves the problem that the water vapor generated by the operation of the existing gas boiler is usually discharged directly, and the direct discharge of water vapor will take away a large amount of water in the boiler, resulting in a waste of water resources.

[0016] 2. In the present invention, by setting up the structures such as the boiler body, the transfer part and the cleaning module, after the steam in the boiler body enters the box of the transfer part, it will push up the piston plate, and then squeeze the folded airbag, so that the gas in the folded airbag is transported to the transmission part of the cleaning module through the transmission pipe, so that the first metal folded hose of the transmission part will expand and extend after receiving the gas, and the second metal folded hose that receives the gas through the first metal folded hose, the adapter plate shell and the joint will also expand and extend, and the extension of the first metal folded hose will push the cleaning connecting plate, the cleaning side plate, the extended cleaning plate and the cleaning middle plate to move to the right, and the extension of the second metal folded hose will additionally push the extended cleaning plate to move an additional distance, so that the cleaning connecting plate can clean the tube surface of the heat exchange tube, so that the cleaning The middle plate can clean the first return smoke tube, and the cleaning side plate and the extended cleaning plate can clean the second return smoke tube, thereby preventing scale from adhering to the surfaces of the first return smoke tube, the second return smoke tube and the heat exchange tube, and affecting the heat exchange performance of the first return smoke tube, the second return smoke tube and the heat exchange tube. The energy-saving gas boiler can automatically clean the scale on the outer surface of the smoke tube to ensure the heat exchange performance of the smoke tube, and avoid increasing the operating power of the burner due to the reduction of the heat exchange performance. The problem that the existing gas boiler will form scale on the outer surface of the smoke tube after heating the moisture in the furnace, thereby affecting the heat exchange efficiency of the smoke tube and further affecting the heating efficiency, and in order to ensure the heating efficiency of the moisture, it is necessary to increase the power consumption of the boiler, resulting in a continuous increase in the power consumption of the boiler with use.

[0039] Workflow: The energy-saving gas boiler operates as follows: Note 1: All electrical appliances in this solution are powered by external power and are controlled by the control box 7; Note 2: The water level in the cylinder 108 is detected by the water level gauge 115. When the water level is insufficient, the water pump mechanism 6 is controlled to add new water to the cylinder 108; Note 3: The flame ejected by the control burner 111 is controlled to heat the furnace 101, and the furnace 101 heats the water in the cylinder 108. At the same time, the operation of the burner 111 generates The high-temperature flue gas will first enter the combustion chamber shell 105, then enter the front smoke box 109 through the first return smoke pipe 104, and then enter the rear smoke box 110 through the second return smoke pipe 107, and finally be discharged through the upper opening of the rear smoke box 110. When passing through the first return smoke pipe 104 and the second return smoke pipe 107, the high-temperature flue gas will exchange heat with the water to assist in heating the water. Note 4: The water vapor flow entering the separation module 4 through the air delivery pipe 34 of the heat exchange part 3 will first contact the fan blade 42 2. The high-speed water vapor flow will push the base tube 421, the spiral path 423 and the limiting convex ring 424 to rotate through the fan blades 422. After passing through the fan blades 422, the water vapor will move downward along the spiral path 423 to rotate. During the rotation process, the speed and direction of the water vapor change, so that most of the water in it is affected by the centrifugal force and is thrown onto the inner wall of the casing 41. The liquid moves downward along the inner wall of the casing 41, passes through the baffle plate 44, and flows back to the inner side of the cylinder 108 through the drain valve pipe 45. The separated high-temperature gas is discharged upward from the middle channel of the base tube 421. During the discharge process, it passes through the filter pad 434, and the filter pad 434 absorbs and filters the residual moisture in the high-temperature gas, thereby reducing the moisture in the high-temperature gas as much as possible. Note 5: The base tube 421 drives the limiting convex ring 424 to rotate, and the rotation of the limiting convex ring 424 can squeeze the limited filter pad 434, so that the moisture absorbed in the filter pad 434 can be squeezed out, so that the filter pad 434 maintains its dryness, water absorption and filtering performance;After the boiler body 1 heats the internal water, a large amount of water vapor will be generated. As the water vapor increases, the furnace pressure will increase accordingly. When it increases to a certain value, the pressure gauge 113 will send an electrical signal to the control box 7, so that the control box 7 controls the connecting valve pipe 26 of the transfer part 2 to open, so that the water vapor in the boiler body 1 flows into the box body 21 of the transfer part 2 through the connecting valve pipe 26, and pushes up the piston plate 23, so that the water vapor enters the heat exchange part 3 through the gas transmission valve pipe 27, and then enters the separation module 4 through the heat exchange part 3. When the high-temperature water vapor passes through the heat exchange tube 32, it will cooperate with the high-temperature flue gas in the first return smoke pipe 104 and the second return smoke pipe 107 to assist in heating the newly added water, so that the burner 111 can pass The newly added water is quickly heated by a small fire with relatively low power, and the separation module 4 can separate the steam and water from the incoming water vapor flow, so that the separated water flows back into the cylinder 108 through the drain valve pipe 45, reducing the amount of new water that the water pump mechanism 6 needs to add, thereby saving the use of water resources, and the separated hot air flow can be connected to the heating pipeline to heat the residence or a certain area, so that the high-temperature steam generated during the operation of the energy-saving gas boiler can cooperate with the high-temperature flue gas in the smoke pipe to assist in heating the new water, so that the burner 111 can quickly heat the new water with relatively low power, and can separate the steam and water from the water vapor so that the separated water can be recycled to save the use of water resources;When it is necessary to clean the scale, after the steam in the boiler body 1 enters the box 21 of the transfer part 2, it will push the piston plate 23 upward, and then squeeze the folded airbag 25, so that the gas in the folded airbag 25 is transported to the transmission part 51 of the cleaning module 5 through the transmission pipe 28, so that the first metal folded hose 513 of the transmission part 51 is unfolded and extended after receiving the gas, and the second metal folded hose 56 that receives the gas through the first metal folded hose 513, the adapter plate shell 52 and the joint 55 is also unfolded and extended. The extension of the first metal folded hose 513 will push the cleaning connecting plate 53, the cleaning side plate 54, the extended cleaning plate 57 and the cleaning middle plate 58 to move to the right, and the extension of the second metal folded hose 56 will additionally push the extended cleaning plate 57 to move an additional distance, so that the cleaning connecting plate 53 can clean the tube surface of the heat exchange tube 32, the cleaning middle plate 58 can clean the first return smoke pipe 104, and the cleaning side plate 54 and the extended cleaning plate 57 can clean the first return smoke pipe 104. The second return smoke pipe 107 is cleaned to prevent scale from adhering to the surface of the first return smoke pipe 104, the second return smoke pipe 107 and the heat exchange tube 32, which affects the heat exchange performance of the first return smoke pipe 104, the second return smoke pipe 107 and the heat exchange tube 32. The cleaned scale can be discharged through the drain valve pipe 114. When the water vapor entering the box body 21 is reduced, the piston plate 23 and the folding airbag 25 will be reset by the elastic force of the reset spring 24, and then the control box 7 will reset the connection due to the decrease of the furnace pressure. The valve tube 26 is closed, and the deployment and reset of the folding airbag 25 will exhaust the cleaning module 5, causing the first metal folding hose 513 and the second metal folding hose 56 to shrink, thereby driving the cleaning connecting plate 53, the cleaning side plate 54, the extended cleaning plate 57 and the cleaning middle plate 58 to reset to the left, so that the energy-saving gas boiler can automatically clean the scale on the outer surface of the smoke pipe to ensure the heat exchange performance of the smoke pipe and avoid increasing the operating power of the burner 111 due to the reduction of heat exchange performance. ;
