Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to an exhaust condenser of a gas boiler. Background Art

[0002] Gas boiler is a kind of equipment that uses natural gas and other fuels for combustion. It is widely used because of its low operating cost, small footprint, simple operation and high thermal efficiency. During the combustion process, gas boilers will produce high-temperature exhaust gas, which is discharged into the air through the chimney, resulting in a large amount of heat loss and increased energy consumption. Therefore, it is very important to configure a condenser for gas boilers to improve energy efficiency. After long-term use, the surface of the condenser tube of the common gas boiler exhaust condenser may corrode or scale, affecting its heat dissipation effect, reducing heat exchange efficiency, and thus increasing energy consumption.

The condenser has the advantages of small size, low cost and easy promotion and application. However, during the operation of the gas boiler exhaust condenser, due to the long-term use of the condenser, a certain amount of dust and dirt will accumulate on the surface of the condenser pipe, which will affect the heat dissipation effect of the condenser pipe and reduce the heat exchange efficiency.

[0027] Working principle of condenser 9: When high-temperature exhaust gas passes through condenser 9, a cooling medium, usually water or other coolant, is provided outside condenser 9. The cooling medium contacts with the high-temperature exhaust gas and transfers the heat in the high-temperature exhaust gas to the cooling medium.

[0028] With the aid of the above technical solution of the utility model, the condenser 9 is easy to disassemble through the setting of the sliding mechanism 8, which is convenient for the staff to detect and clean the condenser 9, ensuring that the surface of the condenser 9 remains clean, thereby facilitating heat transfer, helping to reduce maintenance costs, reducing downtime, improving the reliability of the condenser 9, improving the working efficiency of the condenser and delaying the life of the condenser. Through the setting of the water collection mechanism 6, the water generated during the condensation process can be collected, the latent heat carried in the water can be recycled, the safety of discharge can be improved, and the energy utilization efficiency can be improved, thereby helping to save water resources, reduce the burden on the environment, and be more energy-saving and environmentally friendly, and realize the recycling of resources. Through the integrated setting of the air inlet pipe 2, the condensation pipe 1, and the exhaust hole, the high-temperature exhaust gas discharged by the gas boiler can be fully condensed, and the heat in the high-temperature exhaust gas can be effectively recovered and converted into usable energy, which helps to improve the energy efficiency of the gas boiler exhaust condenser, reduce energy waste, and save fuel costs.

[0029] In one embodiment, for the above-mentioned flange mechanism 3, the flange mechanism 3 includes a flange plate 301 arranged on the outer side of the bottom circumference of the condensation pipe 1, and the flange mechanism 3 also includes a flange plate 302 arranged on the outer side of the top circumference of the intake pipe 2. The flange plate 301 and the flange plate 302 are matched with a plurality of bolts 303, thereby realizing the disassembly and installation of the condenser, facilitating subsequent maintenance and replacement, and extending the service life of the condenser.

[0030] In one embodiment, for the above-mentioned water collecting mechanism 6, the water collecting mechanism 6 includes a fixed plate 601 arranged at the bottom of the condensing pipe 1, a plurality of air inlet holes 602 are opened on the top of the fixed plate 601, and a water collecting bucket 603 is arranged in the middle of the fixed plate 601; a fixed plate 2 604 is arranged on the top of the fixed plate 1 601, a water receiving funnel 605 is arranged in the middle of the fixed plate 2 604, a plurality of through holes 606 are opened in the water receiving funnel 605, and a drain pipe 10 is arranged at the bottom of the water collecting bucket 603, and the drain pipe 10 runs through one side of the condensing pipe 1, so that the water generated during the condensation process can be collected, and the latent heat carried in the water can be recycled, thereby improving the safety of discharge and improving the energy utilization efficiency.

[0031] The working principle of the water collecting mechanism 6 is as follows: the water generated during the condensation process falls into the water collecting funnel 605, the water falls into the water collecting bucket 603 through the through hole 606 on the water collecting funnel 605, and enters the drain pipe 10 through the water collecting bucket 603 to be discharged outward.

[0032] In one embodiment, for the above-mentioned condenser tube cover 4, a mounting seat 11 matched with the condenser tube 9 is provided at the bottom end of the condenser tube cover 4, and a plurality of exhaust holes 12 are opened at the top of the condenser tube cover 4; a mounting seat 13 matched with the condenser tube 9 is provided at the top of the mounting plate 7, and a plurality of exhaust holes 14 are opened at the top of the mounting plate 7, and two sliders 15 are provided on the outer side of the circumference of the mounting plate 7, and the sliding mechanism 8 includes a groove 801 provided on the inner wall of the condenser tube 1, a compression spring 802 is provided inside the groove 801, and two limiting grooves 803 are opened at the top of the groove 801; the sliding mechanism 8 also includes a slide groove 804 provided on the inner wall of the condenser tube 1 and matched with the slider 15, so that the condenser tube 9 is easy to disassemble, which is convenient for the staff to detect and clean the condenser tube 9, ensure that the surface of the condenser tube 9 is kept clean, improve the reliability of the condenser tube 9, and improve the working efficiency of the condenser.

[0033] The working principle of the sliding mechanism 8: the mounting plate 7 slides through the cooperation of the slider 15 and the slide groove 804. The slider 15 slides to the inside of the groove 801 to compress the compression spring 802. Since the condenser tube 9 cooperates with the condenser tube cover 4 and the mounting plate 7, the condenser tube 9 is rotated by rotating the condenser tube cover 4. The rotation of the condenser tube 9 drives the mounting plate 7 to rotate, so that the slider 15 rotates to the inside of the limit groove 803. Through the action of the compression spring 802, the slider 15 cooperates with the limit groove, thereby fixing the mounting plate 7; when the condenser tube 9 needs When cleaning or repairing, the condenser 9 is pressed by pressing the condenser cover 4, and the pressing of the condenser 9 drives the mounting plate 7 to be pressed, so that the slider 15 compresses the compression spring 802. The condenser cover 4 is rotated while compressing, and the slider 15 is rotated, so that the slider 15 cooperates with the slide groove 804. Under the action of the compression spring 802, the slider 15 slides upward and pulls the condenser cover 4, so that the slider 15 loses cooperation with the slide groove 804, and then the condenser is cleaned and repaired to avoid the accumulation of dust and dirt that affects the heat dissipation effect of the condenser.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] In actual application, the staff installs the air intake pipe 2 at one end of the exhaust pipe of the gas boiler. The gas boiler is burned, and the high-temperature exhaust gas generated during the combustion enters the condensation pipe 1 through the air intake pipe 2. The high-temperature exhaust gas enters the bottom of the installation plate 7 through the air intake hole 602 and the through hole 606, and enters the top of the installation plate 7 through the exhaust hole 14 to interact with the condenser 9. The high-temperature exhaust gas is heat exchanged through the condenser 9, and the gas after the heat exchange is discharged outward through the exhaust hole 12. At this time, the water generated during the heat exchange process drips into the water collection mechanism 6 through the exhaust hole 14 for collection (the working principle of the water collection mechanism 6 is as shown above), and the collected water is discharged through the drainage Tube 10 is discharged outward; when the condenser 9 needs to be cleaned or repaired, the bolt 303 is moved to make the flange 1 301 and the flange 2 302 lose their matching, and the condenser 9 is cleaned or repaired by the mutual cooperation between the mounting plate 7 and the sliding mechanism 8 (the working principle of the sliding mechanism 8 is as shown above). After the condenser 9 is cleaned or repaired, the mounting plate 7 and the sliding mechanism 8 are matched to fix the mounting plate 7. After the mounting plate 7 is fixed, the bolt 303 is moved to make the flange 1 301 and the flange 2 302 match, and the condenser cover 4 is fixed, thereby completing the cleaning or repair of the condenser 9 to avoid the accumulation of dust and dirt that affects the heat dissipation effect of the condenser.

[0036] In summary, with the aid of the above technical solution of the utility model, through the setting of the sliding mechanism 8, the condenser 9 is easy to disassemble, and it is convenient for the staff to detect and clean the condenser 9, ensuring that the surface of the condenser 9 remains clean, which is conducive to heat transfer, helps to reduce maintenance costs, reduces downtime, improves the reliability of the condenser 9, improves the working efficiency of the condenser and delays the life of the condenser. Through the setting of the water collection mechanism 6, the water generated during the condensation process can be collected, the latent heat carried in the water can be recycled, the safety of discharge can be improved, and the energy utilization efficiency can be improved, thereby helping to save water resources, reduce the burden on the environment, and be more energy-saving and environmentally friendly, and realize the recycling of resources. Through the integrated setting of the air inlet pipe 2, the condensation pipe 1, and the exhaust hole, the high-temperature exhaust gas discharged by the gas boiler can be fully condensed, and the heat in the high-temperature exhaust gas can be effectively recovered and converted into usable energy, which helps to improve the energy efficiency of the gas boiler exhaust condenser, reduce energy waste, and save fuel costs.
