Technical Field

[0001] The utility model relates to the field of garbage power generation technology, in particular to a garbage pool heating device. Background Art

[0002] In solid waste power generation, the garbage pool needs to be fermented. Fermentation treatment can increase the calorific value and incineration efficiency of the garbage, thereby achieving resource utilization and environmentally friendly treatment of the garbage.

[0003] When the temperature in the garbage pool of the existing solid waste power generation system drops below zero in winter, the low temperature will seriously affect the garbage fermentation process, thereby causing a significant reduction in the power generation per ton of garbage. Utility Model Content

[0004] In order to improve the problem of reduced power generation per ton of garbage when the temperature is low, the utility model provides a garbage pool heating device.

[0007] By adopting the above technical solution, the hot air flow generated by the incinerator enters the main inlet pipe, the heat dissipation coil and the main outlet pipe in sequence. The heat dissipation coil acts on the side wall of the garbage pool, thereby heating the garbage pool. The staff can inspect and repair the heat dissipation coil through the closed door. After the hot air is introduced, the temperature of the garbage pool is effectively increased, thereby increasing the power generation per ton of garbage.

[0008] Optionally, a guide inlet pipe is connected between the top of the heat dissipation coil and the main inlet pipe, a guide outlet pipe is connected between the bottom of the heat dissipation coil and the main outlet pipe, ball valves are installed on the guide inlet pipe and the guide outlet pipe, the heat dissipation coil is connected to the guide inlet pipe, and the heat dissipation coil is flange-connected to the guide outlet pipe.

[0009] By adopting the above technical solution, when the heat dissipation coil needs to be replaced, the ball valve can be closed and the flange connection can be released, which is very convenient for the staff to operate.

[0010] Optionally, a clamp for fixing the heat dissipation coil is detachably mounted on the inner wall of the accommodating cavity.

[0011] By adopting the above technical solution, the clamp can effectively fix the heat dissipation coil and facilitate the disassembly of the heat dissipation coil.

[0012] Optionally, the diversion inlet pipe is inclined downward away from the inlet of the main inlet pipe, and the diversion outlet pipe is parallel to the diversion inlet pipe.

[0013] By adopting the above technical solution, the diversion inlet pipe and the diversion outlet pipe are designed with unique angles, which is convenient for guiding the air flow direction and accelerating heat conduction.

[0014] Optionally, drainage plates with gradually increasing heights are arranged along the fluid flow direction in the main inlet pipe. The drainage plates are located behind the corresponding diversion inlet pipe inlets and are fixedly connected to the bottom wall of the main inlet pipe. The drainage plates are parallel to the diversion inlet pipes.

[0015] By adopting the above technical solution, the drainage plates are used in cooperation with the diversion inlet pipes to enhance the diversion effect.

[0016] Optionally, a heat insulation and heat preservation layer is arranged on the side of the closing door close to the accommodation cavity.

[0017] By adopting the above technical solution, heat dissipation to the outside of the garbage pool is reduced, and the heat preservation performance is improved.

[0018] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0019] The hot air flow generated by the incinerator sequentially enters the main inlet pipe, the heat dissipation coil pipe, and the main outlet pipe. The heat dissipation of the heat dissipation coil pipe acts on the side wall of the garbage pool main body, thereby heating the garbage pool. The staff can perform maintenance work on the heat dissipation coil pipe through the closing door. After introducing the hot air, the temperature of the garbage pool is effectively increased, and thus the power generation per ton of garbage is increased;

[0021] The diversion inlet pipe and the diversion outlet pipe are designed with unique angles, which is convenient for guiding the air flow direction and accelerating heat conduction. Brief Description of the Drawings

[0026] The following is combined with Figure 1 -Attached Figure 3 The utility model is described in further detail.

[0027] The utility model discloses a garbage pool heating device. Figure 1 and Figure 2 The garbage pool heating device includes a main inlet pipe 2, a main outlet pipe 3 and multiple heat dissipation units 4. The high-temperature gas generated during the combustion of garbage in the incinerator is introduced into the pipeline. The heating device is installed in the side wall of the garbage pool body 1.

[0028] Reference Figure 1 and Figure 2 The main body 1 of the garbage pool is a reinforced concrete structure. Four closed doors 10 are hingedly installed on the outer wall of the garbage pool main body 1 corresponding to the heating device. Each closed door 10 corresponds to a heat dissipation unit 4. A accommodating cavity 11 for accommodating the heat dissipation unit 4 is arranged in the side wall of the garbage pool main body 1. An insulation board serving as a heat insulation layer is also installed on the side of the closed door 10 close to the accommodating cavity 11. When the heat dissipation unit 4 needs to be installed or repaired, the corresponding closed door 10 can be opened for independent operation.

[0029] Reference Figure 2 The main inlet pipe 2 is horizontally installed at the top of the side wall of the garbage pool body 1, the main outlet pipe 3 is horizontally installed at the bottom of the side wall of the garbage pool body 1, and the heat dissipation unit 4 is detachably installed between the main inlet pipe 2 and the main outlet pipe 3. The hot gas generated by the incinerator enters through the main inlet pipe 2 located at the top, passes through the heat dissipation unit 4, and is finally discharged from the main outlet pipe 3.

[0030] Reference Figure 2 The heat dissipation unit 4 includes a heat dissipation coil 40, a flow guide inlet pipe 41 and a flow guide outlet pipe 42. The top of the heat dissipation coil 40 is flange-connected to the flow guide inlet pipe 41, and the bottom of the heat dissipation coil 40 is flange-connected to the flow guide outlet pipe 42. The flow guide inlet pipe 41 is connected to the main flow inlet pipe 2, and the flow guide outlet pipe 42 is connected to the main flow outlet pipe 3.

[0031] Reference Figure 2In order to facilitate installation or removal of the heat dissipation coil 40, a ball valve 43 is installed on the flow guide inlet pipe 41 and the flow guide outlet pipe 42 to close the branch in time; a clamp 44 for fixing the heat dissipation coil 40 is installed on the inner wall of the accommodating cavity 11, and the clamp 44 is fixed by screws. In other embodiments, the heat dissipation coil 40 can also be designed to be semi-embedded in the inner wall of the accommodating cavity 11, so that the heat dissipation coil 40 is fully in contact with the concrete structure, which is convenient for heat conduction.

[0032] Reference Figure 2 and Figure 3 In order to facilitate the guidance of the airflow direction and accelerate the heat transfer, the guide inlet pipe 41 is arranged downwardly and tilted away from the inlet of the main inlet pipe 2, and four guide plates 20 with increasing heights are arranged in the guide inlet pipe 41 along the airflow direction. The guide plate 20 corresponds to the rear side of the inlet of the guide inlet pipe 41, and the bottom end of the guide plate 20 is fixedly connected to the main inlet pipe 2. The guide plate 20 is parallel to the guide inlet pipe 41, which is convenient for guiding the airflow from the main inlet pipe 2 into the heat dissipation coil 40; the guide outlet pipe 42 is arranged parallel to the guide inlet pipe 41, which is convenient for guiding the airflow from the heat dissipation coil 40 into the main outlet pipe 3.

[0033] The implementation principle of a garbage pool heating device of an embodiment of the utility model is as follows: after the hot gas generated by the combustion of the incinerator enters the main inlet pipe 2, it enters the guide inlet pipe 41, the heat dissipation coil 40 and the guide outlet pipe 42 in succession under the guidance of the guide plate 20, and is finally discharged from the main outlet pipe 3. The heat emitted by the heat dissipation coil 40 acts on the garbage pool body 1. The on-site test data shows that the temperature of the garbage pool rises to 15°C, which significantly increases the fermentation temperature of the garbage and increases the power generation per ton of garbage from 195 degrees / ton to 350 degrees / ton. If the heat dissipation coil 40 needs to be inspected, the staff opens the closed door 10, closes the corresponding ball valve 43, and removes the restrictions on the heat dissipation coil 40 by the flange connection and the clamp 44. The operation is very convenient.

[0034] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
