Description

Technical Field

[0001] The utility model relates to the field of boilers, in particular to a boiler with flue gas energy recovery processing function. Background Art

[0002] A boiler is an energy conversion device whose basic function is to convert the chemical energy of fuel into thermal energy, and then transfer this thermal energy to water through a heat exchange process to generate hot water or steam. Hot water boilers are mainly used for heating and domestic hot water supply, while the steam generated by steam boilers is widely used in industrial production, power generation, ship propulsion, locomotive power and certain special process.

[0003] Existing boilers usually process and recover boiler flue gas energy through external processing equipment. Since the current boilers themselves do not have energy recovery processing functions, they need to be processed by external processing equipment. The gas is prone to heat loss during transmission to the processing equipment, which affects the energy recovery efficiency and is relatively inconvenient.

[0004] Therefore, it is necessary to design a boiler with flue gas energy recovery treatment that can directly absorb the heat in the exhaust gas in the exhaust pipe through water flow and gas, reduce heat loss during gas transmission, and improve energy recovery efficiency. Utility Model Content

[0005] In order to overcome the shortcomings that the current boiler itself does not have the energy recovery and processing function and needs to be processed by external processing equipment, and the gas is prone to heat loss during transmission to the processing equipment, thereby affecting the energy recovery efficiency, the utility model provides a boiler with flue gas energy recovery processing that can directly absorb the heat in the exhaust gas in the exhaust pipe through water flow and gas, reduce heat loss during gas transmission, and improve energy recovery efficiency.

[0006] The technical solution is: a boiler with flue gas energy recovery and treatment, including a base, a boiler, a smoke exhaust pipe, a heat conduction plate, a working pipeline, a liquid heating mechanism and a gas heating mechanism. The middle part of the base is connected to the boiler, the smoke exhaust pipe is connected to the outside of the boiler, a plurality of heat conduction plates are evenly distributed on the boiler according to the circumference, the middle part of the boiler is connected to the working pipeline, a liquid heating mechanism is arranged between the outsides of the heat conduction plates, and gas heating mechanisms are arranged on the left and right parts of the boiler.

[0007] As an improvement to the above solution, a rotating cover is rotatably provided at the lower left part of the boiler.

[0008] As an improvement of the above solution, the smoke exhaust pipe is wavy.

[0009] As an improvement of the above solution, the working pipeline is made of carbon steel.

[0010] As an improvement of the above scheme, the liquid heating mechanism includes a middle cover, a liquid pipe and a temperature sensor. The middle cover is connected between the outer sides of the heat conduction plates, the middle cover is connected to the smoke exhaust pipe, the front and rear sides of the middle cover are connected to left and right liquid pipes, the upper side of the middle cover is connected to left and right temperature sensors, and the lower part of the middle cover is also connected to front and rear temperature sensors.

[0011] As an improvement of the above scheme, it also includes a gas heating mechanism, which includes an end cover, a connecting pipe and a fan. The left and right parts of the boiler are connected to the end covers, the smoke exhaust pipe passes through the right end cover, the front and rear sides of the end cover are connected to connecting pipes, and the inside of the connecting pipes is connected to the fan.

[0012] Beneficial effect: The utility model absorbs the heat on the heat conduction plate through the water in the middle cover, so that the water in the middle cover becomes hot, and the fan can be started to allow gas to enter the end cover from the front connecting pipe, and the gas absorbs the heat in the exhaust gas in the exhaust pipe, thereby achieving the effect of being able to directly absorb the heat in the exhaust gas in the exhaust pipe through water flow and gas, reducing heat loss in the gas transmission process, and improving energy recovery efficiency.

DETAILED DESCRIPTION

[0019] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0020] A boiler with flue gas energy recovery treatment, such as Figure 1 and Figure 2 As shown, it includes a base 1, a boiler 2, a smoke exhaust pipe 3, a heat conduction plate 4, a working pipe 5, a liquid heat mechanism 6 and a gas heat mechanism 7. The boiler 2 is connected to the middle of the base 1, and a rotating cover is rotatably provided at the lower left part of the boiler 2. The smoke exhaust pipe 3 is connected to the outside of the boiler 2, and the smoke exhaust pipe 3 is wavy. Eight heat conduction plates 4 are evenly distributed on the boiler 2 according to the circumference. The working pipe 5 is connected to the middle of the boiler 2. The working pipe 5 is made of carbon steel and has good high-temperature strength and creep resistance. A liquid heat mechanism 6 that can absorb heat in the exhaust gas through water flow is provided between the outer sides of the heat conduction plates 4, and a gas heat mechanism 7 that can absorb heat in the exhaust gas through gas is provided on the left and right parts of the boiler 2.

[0021] like Figure 1 and Figure 3 As shown, the liquid heating mechanism 6 includes a middle cover 61, a liquid pipe 62 and a temperature sensor 63. The middle cover 61 is connected between the outer sides of the heat conducting plate 4, the middle cover 61 is connected to the smoke exhaust pipe 3, the front and rear sides of the middle cover 61 are connected to the left and right liquid pipes 62, the upper side of the middle cover 61 is connected to the left and right temperature sensors 63, and the lower part of the middle cover 61 is also connected to the front and rear temperature sensors 63.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a gas heating mechanism 7, which includes an end cover 71, a connecting pipe 72 and a fan 73. The left and right parts of the boiler 2 are connected to the end covers 71, the smoke exhaust pipe 3 passes through the right end cover 71, the front and rear sides of the end cover 71 are connected to the connecting pipe 72, and the inside of the connecting pipe 72 is connected to the fan 73.

[0023] When using the device, first place the base 1 in the flue gas energy recovery area, then discharge the water to be boiled into the working pipe 5, then rotate and open the rotating cover, then place the fuel boiler 2 under the bottom, then ignite the fuel, and then rotate and close the rotating cover, and then boil water so that the hot water is discharged from the right part of the working pipe 5. At this time, the exhaust gas generated by the combustion of the fuel enters the exhaust pipe 3, and the water source can be connected to the front liquid pipe 62 to allow the water to enter the middle cover 61, and conduct heat through the heat conduction plate 4. Then, the water in the middle cover 61 absorbs the heat on the heat conduction plate 4, so that the water in the middle cover 61 becomes hot, and then is discharged from the rear liquid pipe 62 to recover the hot water, and the water flow temperature is monitored by the temperature sensor 63. At the same time, the fan 73 can be started to allow the gas to enter the end cover 71 from the front connecting pipe 72, and the gas absorbs the heat in the exhaust gas in the exhaust pipe 3. After the gas becomes hot, it is discharged from the rear connecting pipe 72, so that the heat in the exhaust gas in the exhaust pipe 3 can be directly absorbed by the water flow and the gas, and the heat loss during the gas transmission process can be reduced, thereby improving the energy recovery efficiency.
