Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal equipment, and in particular to an intelligent pre-drying device for garbage entering a furnace. Background Art

[0002] Waste incineration power generation is considered to be the most promising waste treatment technology in the world, but the composition of waste is complex, and the moisture content of waste varies greatly in different seasons and regions. Currently, waste is collected and sent to the waste storage, and the moisture content of the waste entering the furnace can be reduced after fermentation. However, some high-moisture waste still has a high moisture content after dehydration in the pile pit, which will lead to unstable combustion and excessive emissions of pollutants such as dioxins and NOx.

[0003] Therefore, how to effectively reduce the water content of garbage entering the furnace, improve the combustion stability of garbage in the furnace, and effectively control the emission of dioxins and NOx is one of the technical problems that need to be solved in this field. Summary of the invention

[0004] The present invention is intended to provide an intelligent pre-drying device for waste entering the furnace, a device that uses high-temperature steam to pre-dry waste entering the furnace. The purpose is to solve the above-mentioned shortcomings.

[0005] In order to solve the above problems, the present invention provides the following technical solutions: A smart pre-drying device for garbage entering a furnace comprises a shell and a steam coil, wherein the shell comprises an inner cylinder and an outer cylinder, the steam coil is arranged between the inner cylinder and the outer cylinder, and further comprises a fan for blowing air toward the inner cylinder.

[0006] Working principle and beneficial effects of the present invention: The shell includes an inner cylinder and an outer cylinder, and the steam coil is arranged inside (between the inner cylinder and the outer shell). The garbage is sent in from one end of the inner cylinder. Driven by the motor, the inner cylinder can rotate, and the whole device is arranged tilted, so that the garbage can be sent out from the outlet end. High-temperature steam enters from the steam coil inlet on the outlet side, transfers the steam heat to the wall of the inner cylinder, and the wall of the inner cylinder transfers the heat to the garbage through high-temperature radiation, raising the temperature of the garbage and evaporating the moisture in it into water vapor. The fan draws air from the garbage storage and sends the air into the drying device from the garbage inlet side through the air duct, taking away the evaporated water vapor and blowing it into the furnace together.

[0007] By using the garbage pre-drying device, high-temperature steam can exchange heat with the garbage entering the furnace, which can effectively reduce the moisture content of the garbage entering the furnace, improve the stability of combustion, and reduce the generation of pollutants.

[0008] The invention is optimized to further include an incinerator, wherein the incinerator is provided with a temperature sensor, and the temperature inside the incinerator is monitored by the temperature sensor.

[0009] Optimally, the inner drum and the outer drum are coaxially connected for rotation, and further include a motor for driving the inner drum to rotate. The motor drives the inner drum to rotate, so that the garbage is turned over in the inner drum, and the high-temperature steam fully dries the garbage.

[0010] Optimally, the inner cylinder and the outer cylinder are arranged at an angle. By using the inner cylinder and the outer cylinder arranged at an angle, the garbage is gradually poured out during the rotation of the inner cylinder, and the garbage turning efficiency is improved.

[0011] Optimally, the steam coil is provided with a steam flow valve, and the steam flow valve is used to control the steam flow of the steam coil.

[0012] Optimally, the incinerator is connected to the inner drum. The dried garbage is poured into the incinerator for incineration, and the water vapor evaporated from the inner drum is taken away by the fan and blown into the incinerator together. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 Flow chart for handling garbage for this application; Figure 2 This is a schematic diagram of the internal structure of the shell of this application. DETAILED DESCRIPTION

[0014] The following is further described in detail through specific implementation methods: The reference numerals in the drawings of the specification include: inner tube 1, steam coil 2, outer tube 3 In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0015] Example: Refer to Figure 1 and Figure 2 A smart pre-drying device for waste entering a furnace comprises a shell and a steam coil 2. The shell comprises an inner cylinder 1 and an outer cylinder 3. The steam coil 2 is arranged between the inner cylinder 1 and the outer cylinder 3, and further comprises a fan (not shown in the figure) for blowing air toward the inner cylinder 1. The inner cylinder 1 and the outer cylinder 3 are coaxially connected for rotation, and further comprises a motor for driving the inner cylinder 1 to rotate. The shell includes an inner cylinder 1 and an outer cylinder 3, and a steam coil 2 is arranged inside the inner cylinder 1 (between the inner cylinder 1 and the outer shell). The garbage is fed in from one end of the inner cylinder 1. Driven by the motor, the inner cylinder 1 can rotate, and the entire device is arranged at an angle, so that the garbage can be sent out from the outlet end. High-temperature steam enters from the inlet of the steam coil 2 on the outlet side, and transfers the steam heat to the wall of the inner cylinder 1. The wall of the inner cylinder 1 transfers the heat to the garbage through high-temperature radiation, raising the temperature of the garbage and evaporating the moisture therein into water vapor. The fan draws air from the garbage storage and sends the air into the drying device from the garbage inlet side through the air duct, taking away the evaporated water vapor and blowing it into the furnace together.

[0016] By using the garbage pre-drying device, high-temperature steam can exchange heat with the garbage entering the furnace, which can effectively reduce the moisture content of the garbage entering the furnace, improve the stability of combustion, and reduce the generation of pollutants.
