Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of garbage pool heating, in particular to a garbage pool heating device and method for a garbage incineration power plant. BACKGROUND

[0002] Garbage incineration power generation, also known as garbage power generation, is a technology that generates power in the form of heat energy from the final product of garbage disposal. Garbage incineration power generation mainly utilizes the heat energy generated by garbage combustion to produce steam through a boiler, and then extracts power from the steam turbine to ultimately output electric energy. Specifically, garbage is sent into an incinerator and fully combusted at a high temperature of 800-1000℃, and the combustible components in the garbage are oxidized and decomposed to generate a large amount of heat. This heat is used to heat the feed water to convert it into superheated steam, which is then introduced into the steam turbine to drive the turbine to rotate and in turn drive the generator to generate electricity.

[0003] During garbage incineration power generation, the garbage in the garbage pool after fermentation is put into the incinerator, but when the garbage put into the incinerator has a low temperature, it will lower the internal temperature of the incinerator, resulting in unstable heat production of the incinerator and the need to add additional fuel to assist in garbage incineration. In order to avoid this phenomenon, a garbage pool heating device for a garbage incineration power plant is needed.

[0004] In the prior art, an independent heat source is generally used to provide heat for the garbage pool to ensure that the garbage put into the incinerator has a high heat. However, this heating method not only requires additional energy to heat the garbage, but also cannot guarantee the heating effect of the garbage, thereby resulting in low practicality of the existing garbage pool heating device.

[0070] The heating box 5 is arranged on the side wall of the garbage pool body 1. The heating box 5 is provided with a heat exchange component and a filter component. The heating box 5 and the processing box 9 are both filled with heat transfer oil.

[0071] The pumping assembly is arranged on the side wall of the heating box 5 and is used to drive the heat transfer oil to circulate in the heating box 5 and the processing box 9.

[0072] The waste gas generated by incineration is introduced into the treatment box 9 through the air inlet pipe 10, so that the waste gas and the heat transfer oil in the treatment box 9 are mixed, and impurities such as dust carried in the waste gas are adsorbed by the heat transfer oil.

Through the spray component, the contact area between the heat transfer oil and the waste gas is increased, thereby ensuring the heat exchange efficiency.

[0073] Furthermore, the spray assembly includes:

[0074] The connecting seat 17 is provided on the top inner wall of the processing box 9;

[0075] Multiple nozzles 18 are arranged at equal distances at the bottom of the connecting seat 17, and each nozzle 18 is connected to the connecting seat 17.

When the liquid pump is working, the heat-conducting oil at the bottom of the heating box 5 is extracted through the oil extraction pipe, and is transported to the connecting seat 17 through the oil delivery pipe 8, and finally sprayed out through the nozzle 18, thereby increasing the contact area between the heat-conducting oil and the exhaust gas and ensuring the heat exchange efficiency. When the heat-conducting oil in the heating box 5 is extracted, the air pressure inside the heating box 5 is reduced. Under the action of the air pressure, the heat-conducting oil in the processing box 9 is pressed into the heating box 5 through the first connecting pipe 15 to the position above the partition 12.

[0082] Furthermore, the filtering component includes:

[0083] Partition 12, partition 12 is arranged on the inner wall of the heating box 5;

[0084] A plurality of connection holes are equidistantly provided on the top of the partition 12 , and a filter cartridge 13 is provided in each connection hole.

[0095] Turn on the air pump. When the air pump is working, the gas inside the garbage pool body 1 is extracted through the exhaust pipe 20, and the gas is transported to the heat exchange pipe 14 through the air supply pipe 4. After heat exchange with the heat-conducting oil, the hot air enters the air intake seat 19 through the second connecting pipe 22, and finally enters the garbage pool body 1 through the air intake hole 21. The garbage inside the garbage pool body 1 is heated by the high-temperature airflow.

At the same time, the heat carried by the exhaust gas heats the heat-conducting oil, and the pumping component extracts the heat-conducting oil at the bottom of the heating box 5 and sprays it out through the spraying component, thereby increasing the contact area between the heat-conducting oil and the exhaust gas and ensuring the heat exchange efficiency. When the heat-conducting oil in the heating box 5 is extracted, the air pressure inside the heating box 5 is reduced. Under the action of the air pressure, the heat-conducting oil in the treatment box 9 is pressed into the heating box 5 and is at the position of the filter component. Finally, it enters the bottom of the heating box 5 through the filter component, and the heat-conducting oil is filtered by the filter component to achieve the separation of dust impurities. Finally, the gas inside the garbage pool body 1 is extracted through the pumping component, and through the heat exchange between the heat exchange component and the heat-conducting oil, the hot air finally enters the inside of the garbage pool body 1, and the garbage inside the garbage pool body 1 is heated by the high-temperature airflow.

At the same time, the heat carried by the exhaust gas heats the heat-conducting oil. The switch of the liquid pump is turned on. When the liquid pump is working, the heat-conducting oil at the bottom of the heating box 5 is extracted through the oil extraction pipe, and is transported to the connecting seat 17 through the oil delivery pipe 8, and finally sprayed out through the nozzle 18, which increases the contact area between the heat-conducting oil and the exhaust gas and ensures the heat exchange efficiency. When the heat-conducting oil in the heating box 5 is extracted, the air pressure inside the heating box 5 is reduced. Under the action of the air pressure, the heat-conducting oil in the treatment box 9 is pressed into the heating box 5 above the partition 12 through the first connecting pipe 15, and finally passes through the filter cartridge 1 3 enters the bottom of the heating box 5, and the heat transfer oil is filtered by the filter cartridge 13 to separate impurities such as dust. Finally, the air pump is turned on. When the air pump is working, the gas inside the garbage pool body 1 is extracted through the exhaust pipe 20, and the gas is transported to the heat exchange pipe 14 through the gas pipe 4. After heat exchange with the heat transfer oil, the hot air enters the air inlet seat 19 through the second connecting pipe 22, and finally enters the garbage pool body 1 through the air inlet hole 21. The garbage inside the garbage pool body 1 is heated by the high-temperature airflow. The sealing cover 2 allows the airflow to circulate inside the garbage pool body 1 to avoid heat loss, thereby ensuring the heating effect. No independent heat source is required to heat the garbage in the garbage pool body 1, thereby reducing the energy consumption of the device.
