Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture water hanging culture, in particular to a heat energy utilization dust removal device for an aquaculture water temperature heating system. Background Technique

[0002] The water hanging culture of aquatic products is carried out in the culture pond in the factory building. In winter, due to the low water level in the culture pond, the water temperature in the culture pond is relatively low. In order to prevent the death of aquatic products caused by too low temperature, it is necessary to heat the water temperature through a heating system to keep the water temperature in a suitable temperature range.

[0003] At present, the heating device adopted by our company's heating system is as Figure 1 shown. The biomass boiler 10 heats the water transported from the water storage tank. The flue 11 of the biomass boiler 10 is communicated with the smoke inlet pipe 22 of the dust removal device. The lower end of the smoke inlet pipe 22 is close to the water surface 31 in the water tank 30 or extends below the water surface 31. The dust in the flue gas is filtered by water, and the filtered flue gas is discharged from the smoke exhaust pipe. In this process, the flue gas discharged from the biomass boiler 10 into the flue 11 still has a relatively high temperature, and these heats are wasted. In order to utilize the heat of the flue gas in the flue 11, we have improved the existing dust removal device. Summary of the Utility Model

By arranging a partition plate inside the shell of the converter, the shell is divided into a heating chamber located on the upper side and a smoke exhaust chamber located on the lower side. In this way, the heat of the flue gas is dissipated into the heating chamber in the smoke inlet pipe, and then is extracted through the heat delivery pipe to the heat dissipation pipe to heat the water in the filtration pond, so as to utilize the heat in the flue gas.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a heat energy utilization dust removal device for an aquaculture water temperature heating system, including a converter and a water tank. The converter includes a shell, the shell is installed above the water tank, a smoke inlet pipe is arranged inside the shell, one end of the smoke inlet pipe extends downward into the water tank, and the other end passes out from the side of the shell. A smoke exhaust pipe is also installed on the shell. A partition plate is arranged inside the shell, the smoke inlet pipe passes through the partition plate, and the partition plate divides the inside of the shell into a heating chamber located on the upper side and a smoke exhaust chamber located on the lower side.

The heat dissipation pipe is used to be installed in the filtration pond; an air inlet is also arranged on the shell in the heating chamber.

[0006] Fins are installed on the outer wall of the smoke inlet pipe in the heating chamber.

[0007] There are multiple heat dissipation tubes, and both ends of the multiple heat dissipation tubes are respectively communicated with the heat supply pipe through a manifold pipe.

[0008] The heat supply pipe is connected to the air inlet through a return air pipe at the rear end of the heat dissipation tube.

[0009] A balance air inlet is further provided on the return air pipe.

[0010] When in use, the water tank is filled with water, and the lower end of the smoke inlet pipe extends below the water surface.

[0028] Embodiment 1:

[0029] As Figures 1-3 shown, a heat energy utilization and dust removal device for an aquaculture water temperature heating system includes a converter 20 and a water tank 30. The converter 20 includes a housing 21. The housing 21 is installed above the water tank 30. An air inlet pipe 22 is arranged inside the housing 21. One end of the air inlet pipe 22 extends downward into the water tank 30, and the other end passes out from the side of the housing 21. A smoke exhaust pipe 23 is also installed on the housing 21. A partition 24 is arranged inside the housing 21. The air inlet pipe 22 passes through the partition 24. The partition 24 divides the inside of the housing 21 into a heating chamber 25 located on the upper side and a smoke exhaust chamber 26 located on the lower side. The smoke exhaust pipe 23 is communicated with the smoke exhaust chamber 26. A heat delivery pipe 40 is installed on the housing 21 at the position of the heating chamber 25. A fan 41 is installed on the heat delivery pipe 40. A heat dissipation pipe 42 is also installed on the heat delivery pipe 40. The heat dissipation pipe 42 is used to be installed inside the filter pool 50; an air inlet 27 is also arranged in the housing 21 at the heating chamber 25. By arranging the partition 24 inside the housing 21 of the converter 20, the partition 24 divides the inside of the housing 21 into a heating chamber 25 located on the upper side and a smoke exhaust chamber 26 located on the lower side. In this way, the heat of the flue gas is dissipated into the heating chamber 25 in the air inlet pipe 22, and then is drawn out through the heat delivery pipe 40 to the heat dissipation pipe 42 to heat the water in the filter pool 50, so as to utilize the heat in the flue gas.

[0030] In this embodiment, the fan 41 adopts a high-temperature resistant duct fan. In order to ensure that more heat enters the heating chamber 25, a heat insulation layer, such as rock wool, is also wrapped on the outer walls of the flue 11, the heat delivery pipe 40 and the housing 21. The heat insulation layer is not shown in the figure.

[0031] In this embodiment, the air inlet 27 is located on the bottom side of the heating chamber 25, and the heat supply pipe 40 is connected to the top of the heating chamber 25.

[0032] During use, the fan 41 extracts the hot air in the heating chamber 25 and sends it into the heat supply pipe 40, and the cold air enters the heating chamber 25 from the air inlet 27.

[0033] See Figure 2 , further, fins 28 are installed on the outer wall of the smoke inlet pipe 22 located in the heating chamber 25. The heat dissipation area of the smoke inlet pipe 22 in the heating chamber 25 is increased through the fins 28, so that the heat of the flue gas can be better dissipated into the heating chamber 25 and taken away by the air. In this embodiment, the fins 28 are spiral ring fins, or sector fins, or circular ring fins welded on the outer wall of the smoke inlet pipe 22.

[0034] See Figure 5 , there are multiple heat dissipation pipes 42, and both ends of the multiple heat dissipation pipes 42 are respectively communicated with the heat supply pipe 40 through the manifold pipe 43. By arranging multiple heat dissipation pipes 42, it is convenient for the heat in the heat dissipation pipes 42 to be dissipated into the filter tank 50. In this embodiment, two heat dissipation pipes 42 are provided. According to the size of the filter tank 50 and the amount of heat, more than two heat dissipation pipes 42 can also be provided.

[0035] Embodiment Two:

[0036] On the basis of Embodiment One, in winter, since the temperature of the inhaled cold air is relatively low, more heat is required to heat the cold air, resulting in a decrease in the temperature of the air entering the heat supply pipe 40. See Figure 4 , the heat supply pipe 40 is connected to the air inlet 27 through the return air pipe 44 at the rear end of the heat dissipation pipe 42. The air after heat exchange through the heat dissipation pipe 42 is still warmer than the cold air in the room. Through such a structure, an air circulation is formed, which can increase the temperature of the air entering the heat supply pipe 40. The outer wall of the return air pipe 44 is also wrapped with a heat insulation layer.

[0037] Further, see Figure 4 , a balance air vent 45 is also provided on the return air pipe 44. The air pressure of the return air pipe 44 and the heat supply pipe 40 is balanced through the balance air vent 45.

[0038] Embodiment Three:

[0039] See Figure 2 、 3 、4, the water tank 30 contains water during use, and the lower end of the smoke inlet pipe 22 extends 2 - 5 cm below the water surface 31 for dust removal.

[0040] Further, a partition plate 32 is arranged in the water tank 30. The partition plate 32 divides the water tank 30 into a make-up water tank 33 and a dust removal tank 34. The make-up water tank 33 and the dust removal tank 34 communicate with each other below the partition plate 32. The converter 20 is located above the dust removal tank 34. The upper side of the make-up water tank 33 is open, facilitating the observation of the water level and the addition of water. The dust removal tank 34 is closed by the partition plate 32, which can also prevent the flue gas from overflowing into the workshop when dusting the flue gas.

[0041] The operation process or principle of the present utility model is as follows:

[0042] See Figure 4 , when the biomass boiler 10 burns biomass fuel, the circulating water pipes in the biomass boiler 10 are heated. The flue gas after the combustion of the biomass fuel is discharged from the flue 11. The high temperature of the flue gas is dissipated to the heating cavity 25 through the smoke inlet pipe 22. After the fan 41 is started, the fan 41 extracts the hot air in the heating cavity 25 and sends it into the heat delivery pipe 40. The hot air in the heat delivery pipe 40 heats the water in the filtration tank 50 through the heat dissipation pipe 42. The heat-exchanged air returns to the heating cavity 25 through the return air pipe 44.

[0043] The lower end of the smoke inlet pipe 22 extends below the water surface 31 of the water tank 30 to dust the flue gas. The dusted flue gas enters the smoke exhaust cavity 26 and is finally discharged from the smoke exhaust pipe 23.
