Description

Technical Field

[0001] The present application relates to the technical field of boiler components, and in particular to an energy-saving evaporator with a circulating condensation structure. Background Art

[0002] The evaporator is an important component of the boiler. In the existing technology, in order to solve the huge gap in natural gas for heating, one is to open up new sources, and the other is to throttle. Throttling requires improving the efficiency of natural gas boilers to save natural gas. At present, most natural gas boilers are atmospheric fire-grill burners plus copper heat exchanger structures. The flue gas flushes the heat exchanger from bottom to top. In order to ensure that the copper is not corroded by condensed water and the condensed water drips onto the burner when the furnace is shut down, thereby corroding the burner, the design exhaust temperature of the atmospheric boiler is mostly above 130°C. The thermal efficiency of the boiler under rated load is less than 90%. In order to make full use of the energy of natural gas, when the exhaust temperature is lower than 4 At 6℃, the boiler efficiency can reach more than 103%. At this time, a large amount of condensed water is generated. In order to prevent the condensed water from corroding the heat exchanger and burner, stainless steel and extruded aluminum materials are introduced. A cylindrical burner is used on the top. The flue gas flushes the straight tube heat exchanger from top to bottom. A large amount of condensed water is precipitated at the bottom of the heat exchanger. The return water flows from bottom to top. The flue gas and the return water are countercurrent heat exchanged as a whole. Therefore, in the prior art, the evaporator of the small water source heat pump is connected to the condensation section of the boiler. While the compressor of the evaporator is protected by the condensation structure, the flue gas is also condensed and heat exchanged, which plays the role of protecting the device or recovering waste heat. The condensation structure in the existing evaporator mostly arranges condensate in the condenser tube and arranges fins outside the condenser tube to condense the high-smoke gas and recover the heat inside the gas. However, the existing condenser tube is fixedly installed on the evaporator, and the position in contact with the high-temperature gas is relatively fixed, and the condensation effect for the high-temperature gas farther away is poor.

[0003] Therefore, the present invention proposes an energy-saving evaporator with a circulating condensation structure to solve this problem. Summary of the invention

[0009] Furthermore, a water-containing chamber is provided on the push rod, one end of the water-containing chamber is connected to the through pipe, and the other end is connected to the air chamber. A water outlet is provided at one end of the push rod located in the through pipe, and a one-way valve is installed in the water outlet, so that water can only flow from the water-containing chamber to the through pipe. A through opening is provided on the wiper plate, and a one-way valve is also installed in the through opening, so that water in the condensation shell can only flow from the condensation shell to the air chamber in one direction.

[0011] Furthermore, a mounting plate is installed in the condensing shell, the mounting plate is located between the air inlet pipe and the liquid outlet pipe, the rotating plate is rotatably matched with the mounting plate, and a notch is opened on the mounting plate for water to pass through.

[0012] Furthermore, a through hole is provided on the slot, and the through hole enables the interior of the air intake pipe to communicate with the interior of the slot.

[0014] Furthermore, an air guide plate is installed in the condensing shell, and the air guide plate is used to guide the airflow generated by the fan blades to the side of the liquefaction pipe close to the air inlet pipe.

[0015] The beneficial effects of this application are as follows: 1. When the present application is in use, the flue gas is discharged into the liquefaction pipe through the air inlet pipe and the connecting pipe. During the process, the flue gas blows the blades, which drives the connecting pipe and the liquefaction pipe to rotate, thereby increasing the mobility of the liquefaction pipe and increasing the heat exchange effect between the device and the flue gas. During the rotation of the liquefaction pipe, the sponge block is pushed on the spiral groove by the protrusion and pulled by the connecting spring, so that the sponge block slides back and forth in the liquefaction pipe. After the water vapor carried in the flue gas is condensed, the water flow is absorbed by the sliding of the sponge block. When the sponge block slides to conflict with the extrusion block, the water in the sponge block is squeezed out, so that the water falls into the condensation shell and is discharged from the liquid outlet pipe through the cooperation of the drainage piece. When in use, the condensation effect of the device is increased by increasing the mobility of the liquefaction pipe.

[0016] 2. The pulley assembly of the present application includes two pulleys and a belt for connecting the two pulleys, wherein one pulley is connected to a connecting pipe, and the other is connected to a rotating column, so that when the connecting pipe rotates, the fan blades are driven to rotate through the transmission of the pulley assembly, thereby increasing the air flow in the condensation shell, thereby indirectly increasing the effect of condensing the flue gas in the liquefaction pipe, and increasing the practicality of the device.

[0017] 3. In the present application, when the insertion rod is sliding back and forth, the push plate is pushed by the extension plate, thereby causing the push rod to move in a direction away from the through-tube, and the condensed water in the condensation shell is sucked into the through-tube through the water inlet. When the insertion rod is reset and slides, the extension plate releases the resistance to the push plate, and the reset spring pushes the push rod to reset, thereby pushing and squeezing the sucked water for discharge, so that the condensed water in the through-tube is squeezed into the liquid outlet pipe, completing the water circulation. When in use, water is discharged through a relatively simple structure, which increases the practicality of the device.

[0018] 4. In the present application, when the L-shaped plate is inserted into the slot, the temperature is high, which causes the gas inside the L-shaped plate and the air cavity to expand, so that the gas pushes the expansion plate, thereby increasing the width of the wiper plate, so that when the wiper plate moves toward the liquid outlet pipe, it pushes the water in the condensation shell to move toward the water inlet. When there is less condensed water, it is not convenient for the water inlet to directly absorb water, and the condensed water is pushed into the water inlet by the wiper plate, thereby increasing the amount of water near the water inlet and increasing the feasibility of the device. When the wiper plate gradually approaches the through-tube, the L-shaped plate gradually moves away from the slot, thereby reducing the temperature in the air cavity, so that the gas inside the air cavity releases the resistance to the expansion plate, and the pulling spring is reset, thereby driving the expansion plate to reset, thereby reducing the width of the wiper plate, and when the push rod moves in the direction away from the through-tube, due to the smaller width of the wiper plate, less water is moved when the wiper plate is reset, thereby reducing the impact on the water output of the water inlet.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] Embodiment 1 like Figure 1 - Fig.13 As shown, an energy-saving evaporator with a circulating condensation structure proposed in the first embodiment of the present application includes a boiler shell 1, on which an evaporator shell 101 is installed, and components such as a steam drum, a superheater and a reheater are installed in the evaporator shell 101 for connection. A burner is arranged in the boiler shell 1 for heating water. The device burns fuel and heats water by the burner in the boiler shell 1 in cooperation with the components in the evaporator shell 101, and also includes: The condensation shell 2 is provided with a liquid outlet pipe 201 connected to the boiler shell 1. The liquid outlet pipe 201 is used to return the condensed water to the boiler shell 1 for water circulation. The device is not suitable for boilers that heat drinking water. The condensing shell 2 is also provided with an air inlet pipe 202 connected to the evaporator shell 101. A connecting pipe 3 is rotatably installed in the condensing shell 2. The connecting pipe 3 is connected to the air inlet pipe 202. A liquefied pipe 301 is eccentrically installed on the connecting pipe 3. An interlayer 302 for accommodating condensed liquid is provided on the wall thickness of the liquefied pipe 301. A blade 303 is installed on the connecting pipe 3. The blade 303 is rotatably installed in the air inlet pipe 202. The liquefied pipe 301 has two symmetrical blades on the connecting pipe 3. When the airflow passes through the air inlet pipe 202, it is pushed tangentially. The blades 303 rotate, thereby driving the connecting pipe 3 to rotate, so that the liquefied pipe 301 makes a circular motion around the axis of the connecting pipe 3, thereby increasing the movement amplitude of the liquefied pipe 301, so that the contact surface of the liquefied pipe 301 with the air is increased, thereby increasing the effect of condensing the flue gas in the liquefied pipe 301, and then exchanging the heat in the flue gas. Fins can also be installed on the outside of the liquefied pipe 301 to increase its contact area with the air. For the convenience of observation, the fins are not shown in the drawings of the specification; The rotating plate 4 is rotatably mounted in the condensing shell 2. An insertion rod 401 is slidably mounted on the rotating plate 4. The insertion rod 401 is used to be inserted in the liquefied pipe 301. The free end of the liquefied pipe 301 is provided with an outlet. The insertion rod 401 is inserted in the outlet to block or unblock the outlet. A receiving cylinder 402 movably matched with the insertion rod 401 is installed in the condensing shell 2. The number of the insertion rods 401 is the same as the number of the liquefied pipes 301, but all the insertion rods 401 are connected by a rod body, which is movably installed in the receiving cylinder 402 and can rotate and slide in the receiving cylinder 402. A connecting spring 403 is installed between the accommodating cylinder 402 and the insertion rod 401. A spiral groove 404 and a straight groove 405 are provided on one end of the insertion rod 401 inserted in the accommodating cylinder 402. The spiral groove 404 and the straight groove 405 are provided on the above-mentioned rod body. The two ends of the straight groove 405 are respectively connected to the two ends of the spiral groove 404. A convex block 406 that slides with the straight groove 405 or the spiral groove 404 is installed in the accommodating cylinder 402. When the connecting pipe 3 drives the liquefied pipe 301 to rotate, the liquefied pipe 301 is connected to the liquefied pipe 301 through the connecting pipe 3. 01 pushes the side wall of the insertion rod 401, so that the rotating plate 4 rotates together, and because the accommodating cylinder 402 is fixedly installed in the condensing shell 2, when the insertion rod 401 rotates, the protrusion 406 slides in the spiral groove 404 along the tangential direction and pushes the insertion rod 401 close to the liquefied pipe 301. When the protrusion 406 rotates into the straight groove 405, the connecting spring 403 pulls the insertion rod 401 to reset, so that it is away from the liquefied pipe 301, and completes the reciprocating motion of the insertion rod 401 in the liquefied pipe 301; A sponge block 407 is installed at one end of the insertion rod 401 located inside the liquefied pipe 301, and an extrusion block 304 is installed at the mouth of the liquefied pipe 301. The extrusion block 304 reduces the diameter of the mouth of the liquefied pipe 301. When the insertion rod 401 is close to the inside of the liquefied pipe 301, the sponge block 407 is driven to absorb the condensed water of the liquefied pipe 301. When the insertion rod 401 moves toward the mouth of the liquefied pipe 301, the sponge block 407 is squeezed by the extrusion block 304 to squeeze out the water inside, so that the condensed water falls into the inside of the condensation shell 2, and the condensed gas is also discharged into the condensation shell 2 to provide a sufficient gas source for subsequent operations; The drainage member 5 is installed in the condensation shell 2. The drainage member 5 is used to discharge the condensed water in the condensation shell 2 into the liquid outlet pipe 201. After the condensed water is discharged into the condensation shell 2, the condensed water in the condensation shell 2 is discharged back into the boiler shell 1 through the liquid outlet pipe 201 by the drainage member 5, completing the water circulation, increasing the utilization rate of the water in the flue gas, and increasing the practicality of the device; When the insertion rod 401 is inserted into the liquefied pipe 301, the condensed water and the flue gas coexist, and the heat in the flue gas can directly heat the condensed water. When the insertion rod 401 moves out of the liquefied pipe 301, the heated condensed water is taken out, and the cold air in the condensation shell 2 can enter the liquefied pipe 301, which is convenient for condensing the subsequent flue gas. Compared with the prior art, when in use, the flue gas is discharged into the liquefaction pipe 301 through the air inlet pipe 202 and the connecting pipe 3. During the process, the flue gas blows the blades 303, so that the connecting pipe 3 and the liquefaction pipe 301 are driven to rotate, thereby increasing the mobility of the liquefaction pipe 301 and increasing the efficiency of heat exchange between the device and the flue gas. During the rotation of the liquefaction pipe 301, the spiral groove 404 is pushed by the protrusion 406 and the connecting spring 403 is pulled, so that the sponge block 407 slides back and forth in the liquefaction pipe 301. After the water vapor carried in the flue gas is condensed, the water flow is absorbed by the sliding of the sponge block 407. When the sponge block 407 slides to conflict with the squeezing block 304, the water in the sponge block 407 is squeezed out, so that the water falls into the condensation shell 2 and is discharged from the liquid outlet pipe 201 through the cooperation of the drainage member 5. When in use, the condensation effect of the device is increased by increasing the mobility of the liquefaction pipe 301.

[0022] Embodiment 2 like Figure 8As shown, the second embodiment further discloses the condensation shell 2, the connecting pipe 3, the rotating plate 4 and the drainage member 5 on the basis of the first embodiment. In the second embodiment, a rotating column 305 is rotatably installed in the condensation shell 2, and the rotating column 305 is connected to the connecting pipe 3 through a pulley assembly. A fan blade 20 is installed on the free end of the rotating column 305. The pulley assembly includes two pulleys and a belt for connecting the two pulleys, one of which is connected to the connecting pipe 3, and the other is connected to the rotating column 305, so that when the connecting pipe 3 rotates, the fan blade 20 is driven to rotate through the transmission of the pulley assembly, thereby increasing the air flow in the condensation shell 2, increasing the cooling effect of the device on the liquefaction pipe 301, and indirectly increasing the effect of condensing the flue gas in the liquefaction pipe 301, thereby increasing the practicality of the device.

[0023] like Figure 4 As shown, in the second embodiment, the drainage member 5 includes a push plate 502 slidably installed in the condensation shell 2 through a reset spring 501, a push rod 505 is installed on the push plate 502, a through pipe 503 connected to the liquid outlet pipe 201 is installed in the condensation shell 2, the push rod 505 is used to be inserted in the through pipe 503, a water inlet 504 is opened on the through pipe 503, a one-way valve is installed in the water inlet 504, so that water can only flow from the water inlet 504 to the through pipe 503 in one direction, an extension plate 408 is installed on the insertion rod 401, and the push plate 502 is located on the side of the extension plate 408 away from the liquid outlet pipe 201. When in use, the push rod 505 and the through pipe 503 form a piston structure When the insertion rod 401 is sliding back and forth, the extension plate 408 pushes the push plate 502, so that the push rod 505 moves in a direction away from the through pipe 503, and the condensed water in the condensation shell 2 is sucked into the through pipe 503 through the water inlet 504. When the insertion rod 401 is reset and slid, the extension plate 408 releases the resistance to the push plate 502, and the reset spring 501 pushes the push rod 505 to reset, thereby pushing and squeezing the sucked condensed water for discharge, so that the condensed water in the through pipe 503 is squeezed into the liquid outlet pipe 201, completing the water cycle. When in use, water is discharged through a relatively simple structure, which increases the practicality of the device. The through pipe 503 is connected to the boiler shell 1, and the liquid outlet pipe 201 is connected to the outside through an additional pipe. The pipe opening of the pipe is opened in the vertical upward direction. The pipe is not shown in the drawings of the specification for the convenience of display. The condensed water enters the boiler shell 1 through the through pipe 503, and the flue gas is discharged through the above-mentioned pipe when passing through the liquid outlet pipe 201, thereby improving the feasibility of the device. In order to facilitate display, the water inlet 504 in the attached drawings of the specification is opened on the side wall of the through pipe 503. In actual application, it is opened toward the bottom of the condensation shell 2, and some water is injected into the condensation shell 2 before the device is used, which acts as a liquid seal, reducing the possibility of flue gas returning to the boiler through the through pipe 503. Water is injected into the condensation shell 2 in advance, so that after the first batch of flue gas enters the condensation shell 2 from the liquefaction pipe 301 along with the condensed water, it will continue to exchange heat with the water in the condensation shell 2, further increasing the heat recovery effect in the flue gas, and making the temperature in the condensation shell 2 lower than the temperature in the liquefaction pipe 301, maintaining the temperature difference, and facilitating the device to condense the flue gas.

[0024] like Figure 4 , Fig. 9 and Fig.11 As shown, in the second embodiment, a wiper plate 6 is installed on the free end of the push rod 505, and an air cavity 601 is opened on the wall thickness of the wiper plate 6. An extension plate 602 is slidably installed on the wiper plate 6 by pulling the spring 605. The end of the extension plate 602 is inserted in the air cavity 601. A slot 603 is opened on the wall thickness of the air inlet pipe 202. An L-shaped plate 604 for inserting in the slot 603 is installed on the wiper plate 6. The L-shaped plate 604 is a hollow structure, and the cavity of the L-shaped plate 604 is connected with the air cavity 601. Since the wiper plate 6 is connected to the push rod 505, when the push rod 505 slides back and forth, it drives the wiper plate 6 to reciprocate in the condensation shell 2, and then drives the L-shaped plate 604 to reciprocate in the slot 603. When the L-shaped plate 604 is inserted into the slot 603, the temperature is high, so that the gas inside it and the gas cavity 601 expands, so that the gas pushes the expansion plate 602, so that the width of the wiper plate 6 increases, so that when the wiper plate 6 moves toward the liquid outlet pipe 201, it pushes the water in the condensation shell 2 to move toward the water inlet 504. When there is less condensed water, it is not convenient for the water inlet 504 to directly absorb water. Therefore, the condensed water is moved into the water inlet 504 through the wiper plate 6, and the water volume near the water inlet 504 is increased, which increases the feasibility of the device. When the wiper plate 6 gradually approaches the through pipe 503, the L-shaped plate 604 gradually moves away from the slot 603, thereby reducing the temperature in the air cavity 601, so that the gas in the air cavity 601 releases the resistance to the expansion plate 602, so that the pull spring 605 is reset, and then the expansion plate 602 is reset, so that the width of the wiper plate 6 is reduced, and then when the push rod 505 moves away from the through pipe 503, the width of the wiper plate 6 is small, and then when the wiper plate 6 is reset, the amount of water moved is small, thereby reducing the impact on the water output of the water inlet 504; Because the water flow has inertia when the wiper 6 moves the water flow, when the wiper 6 is reset, that is, when the push rod 505 allows the through pipe 503 to absorb water, the moved water flow can still move to the water inlet 504 through inertia, and the water moving to the water inlet 504 is the water located on the side of the wiper 6 facing the through pipe 503. When the wiper 6 is reset, firstly, the width is reduced, and secondly, the water pushed is the water on the side away from the through pipe 503, thereby greatly reducing the impact on the water volume at the water inlet 504 and increasing the feasibility of the device.

[0025] like Fig.11 and Fig.13 As shown, in the second embodiment, a water containing chamber 7 is provided on the push rod 505, one end of the water containing chamber 7 is communicated with the through pipe 503, and the other end is communicated with the air chamber 601, and a water outlet 8 is provided on one end of the push rod 505 located in the through pipe 503, and a one-way valve is installed in the water outlet 8, so that the water flow can only flow from the water containing chamber 7 to the through pipe 503, and a through port 9 is provided on the wiper plate 6, and a one-way valve is also installed in the through port 9, so that the water in the condensation shell 2 can only flow from the condensation shell 2 to the air chamber 601 in one direction, and the through port 9 is provided on the side of the wiper plate 6 facing the through pipe 503; When the wiper blade 6 moves toward the through pipe 503, the condensed water will enter the air cavity 601 through the through port 9. At this time, the wiper blade 6 is still close to the air inlet pipe 202, and the gas inside it is still in an expanded state to squeeze the water entering the air cavity 601. Since a one-way valve is installed in the through port 9, the water entering the air cavity 601 can only flow into the water containing cavity 7, move toward the water outlet 8, and enter the through pipe 503 through the water outlet 8. Since a one-way valve for one-way water outlet is also installed at the water outlet 8, the push rod 505 will not leak when pressurized as a piston, thereby increasing the feasibility of the device. Through the above arrangement, more condensed water can enter the through pipe 503, thereby increasing the practicality of the device. Among them, in the embodiment, the push rod 505 not only plays the role of a piston rod, but also plays the role of a pipe, thereby increasing the practicality of the push rod 505, and the wiper blade 6 not only moves the condensed water through the rigidity of its own plate body, but also moves the water flow through air expansion, which also increases the practicality of the wiper blade 6.

[0026] like Figure 7 As shown, in the second embodiment, the rotating plate 4 is a hollow structure, a guide cylinder 10 is installed on the rotating plate 4, and a guide rod 11 slidably inserted in the guide cylinder 10 is installed on the extension plate 408. When the insertion rod 401 slides, the guide cylinder 10 restricts the side wall of the guide rod 11, so that the insertion rod 401 can only approach or move away from the liquefied pipe 301 in a straight line direction, thereby increasing its stability when sliding; The interior of the guide cylinder 10 is connected to the cavity of the rotating plate 4. The rotating plate 4 is provided with a secondary pipe 12 for one-way air intake. A one-way valve is installed in the secondary pipe 12 so that the airflow can only enter the secondary pipe 12 in one direction. The rotating plate 4 is provided with an L-shaped tube 13 for communicating with the interior of the liquefied tube 301. A one-way valve is also provided in the L-shaped tube 13 so that the airflow can only enter the liquefied tube 301 from the L-shaped tube 13. When the device is in use, the rotating plate 4 is not only used as a component for installation, but also can be used as a piston. When the insertion rod 401 is away from the liquefied pipe 301, the guide rod 11 is also driven away from the guide cylinder 10, so that the auxiliary pipe 12 draws air into the cavity of the rotating plate 4. When the insertion rod 401 is close to the liquefied pipe 301, the pressure applied by the guide rod 11 pushes the air in the rotating plate 4 into the liquefied pipe 301, and blows air into the liquefied pipe 301, thereby increasing the condensation effect of the device, so that the sponge block 407 at this time can absorb more condensed water, further increasing the cleaning effect of the condensed water in the liquefied pipe 301, and also facilitating the condensed water to better enter the condensation shell 2, thereby increasing the practicality of the device.

[0027] Embodiment 3 like Figure 1 - Fig.13 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a mounting plate 14 is installed in the condensing shell 2, and the mounting plate 14 is located between the air inlet pipe 202 and the liquid outlet pipe 201. The rotating plate 4 rotates with the mounting plate 14, and a notch 15 for water to pass through is opened on the mounting plate 14. The fan blades 20 are installed on the top of the condensing shell 2, and the notch 15 is opened at the bottom of the mounting plate 14. The hot air has a light density and is mostly at the top. Therefore, the mounting plate 14 can play a role of separation. When in use, the condensing shell 2 is divided into two parts by the mounting plate 14, which plays a certain role of isolation, so that the temperature of the side of the condensing shell 2 close to the through pipe 503 is lower, which is convenient for the wiper plate 6 to cool down better, and the sensitivity of air expansion and release of expansion in the wiper plate 6 is increased. The mounting plate 14 can also be used to block the airflow generated by the fan blades 20, so that it preferentially cools the side where the liquefied pipe 301 is installed, thereby increasing the condensation effect of the device.

[0028] In the third embodiment, a through hole 16 is opened on the slot 603, and the through hole 16 connects the interior of the air inlet pipe 202 with the interior of the slot 603. The through hole 16 enables the flue gas in the air inlet pipe 202 to directly heat the L-shaped plate 604, thereby increasing the feasibility of the device. Moreover, this part of the flue gas is relatively small, and even if it enters the condensation shell 2, it will be condensed in the condensation shell 2.

[0029] In the third embodiment, a T-rod 17 penetrating the sponge block 407 is installed on the insertion rod 401, and a side groove 18 for accommodating the T-rod 17 is opened in the liquefaction tube 301. The maximum width of the T-rod 17 is larger than the pipe mouth of the liquefaction tube 301. The side groove 18 slides with the T-rod 17, which will not affect the sliding of the insertion rod 401, and the T-rod 17 is restricted by the inner wall of the side groove 18, so that when the insertion rod 401 is away from the liquefaction tube 301, the two will not move away from each other and separate, thereby increasing the feasibility of the device.

[0030] In the third embodiment, a wind guide plate 19 is installed in the condensing shell 2, and the wind guide plate 19 is used to guide the airflow generated by the fan blades 20 to the side of the liquefaction pipe 301 close to the air inlet pipe 202. The shape of the wind guide plate 19 is as follows: Fig. 9 As shown, when the fan blades 20 blow out airflow, the airflow is first blown toward the liquefaction pipe 301 through the inclined surface on the air guide plate 19 to cool it, further increasing the condensation effect of the device.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
