[0002] A heating boiler is a device used to meet people's winter heating needs. The breeding industry occupies a very important position in China. In winter, especially in the north, the insulation of breeding greenhouses is the key to the survival rate of breeding. Generally, coal is burned in boilers in breeding houses. Most boilers discharge flue gas into the atmosphere without treatment. The discharged flue gas has a very high temperature and contains a part of heat, resulting in partial waste of heat. At the same time, the temperature of the return water in the breeding house is extremely low. The return water with extremely low temperature directly flows into the boiler for heating, resulting in high energy consumption. Traditional heating boilers have problems such as high energy consumption, low thermal efficiency, large volume, high construction cost, and high labor intensity. Therefore, there is an urgent need for a device that can reuse the flue gas discharged from the boiler. Content of the Utility Model

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0024] Embodiment 1:
[0025] As Figures 1-5 shown, a heating boiler includes a heating boiler and a water tank connected to the boiler. The interior of the heating boiler is divided into a preheating section 4, a heating section 2, and a combustion section 1. A main water distribution plate 501 is provided in the preheating section 4. The main water distribution plate 501 is vertically arranged, dividing the preheating section 4 into a first preheating section and a second preheating section. A water passing port 502 is provided at the middle upper position of the main water distribution plate 501 to connect the water chambers 401 of the first preheating section and 402 of the second preheating section.
[0026] The preheating section 4, the heating section 2, and the combustion section 1 are all provided with smoke chambers. After the hot smoke enters the smoke chambers, its speed is reduced, so that the impurities carried in the smoke are deposited in the smoke chambers, and then are cleaned through the ash cleaning ports provided on the side walls or upper walls of the smoke chambers to avoid blockage of the smoke pipes. A first smoke chamber 301 is provided below the first preheating section, a second smoke chamber 303 is provided above the first preheating section, a third smoke chamber 305 is jointly provided below the first preheating section and the second preheating section, and a fourth smoke chamber 307 is jointly provided above the second preheating section and the heating section 2. Smoke pipes 403 are provided between the first smoke chamber 301, the third smoke chamber 305 and the second smoke chamber 303, the fourth smoke chamber 307. Multiple smoke pipes 403 are vertically arranged, and there are gaps between the smoke pipes 403. The first smoke chamber 301, the third smoke chamber 305 are connected and communicated with the second smoke chamber 303, the fourth smoke chamber 307 by relying on the smoke pipes 403. A fifth smoke chamber 309 is jointly provided below the combustion section 1 and the heating section 2. The fourth smoke chamber 307 and the fifth smoke chamber 309 are communicated through the gap of the heating water pipes 201 in the heating section 2. The fifth smoke chamber 309 and the combustion section 1 are communicated through the gap of the bottom heating main pipe 101. The bottom heating auxiliary pipe 102 is arranged at the boundary between the heating section 2 and the combustion section 1 in the fifth smoke chamber 309. Multiple bottom heating main pipes 101 are horizontally arranged, and there are gaps between each of them. Multiple bottom heating auxiliary pipes 102 are vertically arranged, and there are gaps between each of them. The bottom heating main pipe 101 and the auxiliary pipe 102 are arranged in a "factory" shape. The hot smoke and the flame pass downward through the gaps of the bottom heating main pipe 101 to heat the water in the bottom heating main pipe 101, and then enter the fifth smoke chamber 309. The hot smoke passes through the bottom heating auxiliary pipe 102 to heat the water in the bottom heating auxiliary pipe 102, making full use of the heat in the flame and the hot smoke.
[0027] Inside the heating section 2, there is a heating water pipe 201. Hot smoke enters the heating section 2 from the fifth smoke chamber 309 upwards, passes through the gaps of the heating water pipe 201, and heats the water inside the heating water pipe 201. The heating water pipes 201 inside the heating section 2 are arranged alternately upwards in a zigzag shape. When the hot smoke passes through the gaps of the heating water pipe 201, it repeatedly heats the water inside the heating water pipe 201, improving the heating efficiency and maximizing the utilization of the heat of the hot smoke. At the zigzag corners of each heating water pipe 201, there are mutually separated heating water tanks 202, and the uppermost heating water tank 202 extends to the upper wall and is connected to the water outlet 203.
[0028] There are multiple ventilation openings 104 provided on the side wall of the furnace chamber. An integral air guide cover 106 is provided at the outer end of the ventilation opening 104. The upper part of the air guide cover is closed on the left and right and open at the lower part. A unified air guide cover 107 is provided at the inner end of the ventilation opening 104 or an independent air guide cover 107 is provided for each opening. The air guide cover is arranged in a U shape, closed at the upper and lower parts and open at the left and right. The air guide cover makes the incoming air not blow directly on the flame, which not only increases the oxygen for combustion but also avoids a large amount of air concentrating on the flame and affecting the combustion efficiency. At the same time, the setting of the air guide cover avoids dust when filling fuel into the combustion section and foreign objects entering the ventilation opening and affecting the ventilation efficiency. The combustion section 1 takes in air from the opening at the lower part of the air guide cover 106 at the outer end of the ventilation opening, enters the furnace chamber through the ventilation opening 104, and exits from the left and right of the air guide cover 107. The flame and hot smoke generated by combustion pass downwards through the gap of the furnace bottom heating main pipe 101 and enter the fifth smoke chamber 309. The hot smoke passes through the gap of the furnace bottom heating sub-pipe 102 and enters the heating section, passes upwards through the gap of the heating water pipe 201 and enters the fourth smoke chamber 307, then passes downwards through the second preheating section smoke pipe 403 and enters the third smoke chamber 305, enters the second smoke chamber 303 upwards through the first preheating section smoke pipe 403, passes downwards through the first preheating section smoke pipe 403 and enters the first smoke chamber 301, and is then discharged through the exhaust pipe 312. When in the fifth smoke chamber 309 and the heating section 2, the hot smoke heats the water in the water pipe inside the smoke chamber. When in the second preheating section smoke pipe 403 and the first preheating section smoke pipe 403, it preheats the cold water in the second preheating section water chamber and the first preheating section water chamber outside the smoke pipe. The smoke and water are in the same chamber but in different directions and different diameters, and are respectively set as smoke pipe water chambers or water pipe smoke chambers. They move towards each other in the same space, improving the space utilization rate, reducing the volume, and lowering the manufacturing cost. When the hot smoke leaves the heating section, there is still some heat, which preheats the cold water in the preheating section after entering the preheating section smoke pipe, fully utilizes the heat, improves the heating efficiency, reduces the use cost, and saves resources.
[0029] The return chilled water after heat release through the external cycle enters through the water return port 404. After entering the water chamber 401 of the first preheating section, it is preheated by the hot flue gas in the flue pipes 403 of the first preheating section. Then it enters the water chamber 402 of the second preheating section through the water passing port 502 provided on the total water distribution board 501, and is preheated by the hot flue gas in the flue pipes 403 of the second preheating section. It enters the bottom water tank 105 through the water chamber 402 of the second preheating section, enters the heating water pipes through the main bottom heating pipe 101 and the auxiliary bottom heating pipe 102, and is heated by the flame and hot flue gas generated by the combustion boiler. It alternately enters the heating water tanks 202 which are separated from each other and arranged on the front and rear walls through the heating water pipes 201 upwards. After entering the heating water tank 202 provided on the upper wall, it is discharged from the water outlet 203, and the discharged hot water undergoes heat release through the external cycle.
[0030] The above has made a detailed description of the present utility model. As described above, the above is only a preferred embodiment of the present utility model, and it cannot limit the scope of implementation of the present utility model. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present utility model.
