Description

Technical Field

[0001] The invention belongs to the technical field of garbage pool heating, and in particular relates to a heating device and method for a garbage pool in a garbage incineration power plant. Background Art

[0002] Waste incineration power generation, also known as garbage power generation, is a technology that uses the final product of garbage treatment to generate electricity in the form of thermal energy. Waste incineration power generation mainly uses the heat energy generated by garbage combustion to generate steam through a boiler, and then extracts power from a steam turbine to finally output electrical energy. Specifically, the garbage is sent to the incinerator and fully burned at a high temperature of 800℃ to 1000℃. The combustible components in the garbage are oxidized and decomposed, generating a large amount of heat. This heat is used to heat the feed water and convert it into superheated steam. The steam is then led to the steam turbine to drive the turbine to rotate, thereby driving the generator to generate electricity.

[0003] When garbage is incinerated to generate electricity, the fermented garbage in the garbage pool is put into the incinerator. However, when the temperature of the garbage put into the incinerator is low, the internal temperature of the incinerator will be lowered, resulting in unstable heat generation in the incinerator and the need to add additional fuel to assist the incineration of the garbage. In order to avoid this phenomenon, a heating device for the garbage pool of 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 content. However, this heating method not only requires additional energy to heat the garbage, but also cannot guarantee the heating effect of the garbage, which leads to the low practicality of the existing garbage pool heating device. Summary of the invention

[0005] The object of the present invention is to provide a temperature raising device and method for a garbage pool of a garbage incineration power plant, so as to solve the technical problems in the prior art.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: A heating device for a garbage pool in a garbage incineration power plant, comprising: Garbage pool body; A processing box, which is arranged on the outer side wall of the garbage pool body; A filter screen is arranged on the inner wall of the processing box; An output pipe, which is arranged on the side wall of the processing box above the filter screen; An air inlet pipe is arranged on the side wall of the treatment box below the filter screen; A spray assembly, which is arranged on the inner wall of the top of the processing box; A heating box is arranged on the side wall of the garbage pool body, a heat exchange component and a filter component are arranged in the heating box, and both the heating box and the treatment box are filled with heat transfer oil; A pumping assembly is arranged on the side wall of the heating box and is used to drive the heat transfer oil to circulate in the heating box and the processing box.

[0009] A further improvement of the present invention is that the filter assembly comprises: A partition, which is arranged on the inner wall of the heating box; A plurality of connection holes are equidistantly arranged on the top of the partition plate, and a filter cartridge is arranged in each connection hole.

[0010] A further improvement of the present invention is that the heat exchange component comprises: Heat exchange tubes, which are arranged in the heating box; A second connecting pipe, which is arranged at one end of the heat exchange pipe and passes through the inner wall of the garbage tank body; The gas delivery pipe is arranged at the other end of the heat exchange pipe and passes through the side wall of the heating box.

[0013] A further improvement of the present invention is that a sealing cover is connected to the top of the garbage pool body.

[0014] A further improvement of the present invention is that a cover is hingedly connected to the top of the heating box.

[0015] A method for heating a garbage pool in a garbage incineration power plant, based on the heating device for heating a garbage pool in a garbage incineration power plant, comprises: The waste gas generated by incineration is introduced into the treatment box through the air intake pipe, so that the waste gas and the heat transfer oil in the treatment box are mixed, and the dust impurities carried in the waste gas are adsorbed by the heat transfer oil.

At the same time, the heat carried by the waste gas heats the heat transfer oil, and the contact area between the heat transfer oil and the waste gas is increased through the spray assembly, thereby ensuring the heat exchange efficiency. The heated heat transfer oil is transported to the heating box by the pumping assembly, and the dust carried by the heat transfer oil is filtered through the filtering assembly in the heating box. Then, the gas entering the garbage pool body is heated through the heat exchange assembly, and there is no need for an independent heat source to heat the garbage in the garbage pool body, thereby reducing the energy consumption of the device.

When the heat transfer 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 transfer oil in the treatment box 9 is pressed into the heating box 5 at the position of the filter component, and finally enters the bottom of the heating box 5 through the filter component.

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. Through the effect of the sealing cover 2, the airflow circulates 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.
