Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, and more specifically, to a garbage treatment incinerator for use in a garbage incineration power plant. Background Art

[0002] With the rapid process of urbanization, the generation of municipal solid waste has increased sharply, posing severe challenges to environmental sustainability and urban management. Waste incineration power generation, as an efficient waste reduction and energy recovery technology, is playing an increasingly important role. In the waste incineration power generation system, the incinerator is the core equipment, and its design and technical performance directly affect the efficiency of waste treatment, environmental protection emission standards, and the effect of energy recovery.

[0003] Traditional waste incinerators usually include types such as grate furnaces, circulating fluidized bed furnaces, and rotary furnaces.

[0004] Grate furnaces are widely used due to their simple operation and wide applicability, but they have problems such as incomplete combustion and low thermal efficiency. Summary of the Utility Model

[0005] Based on the above technical problems, the utility model proposes a garbage treatment incinerator for use in a garbage incineration power plant.

[0006] The garbage treatment incinerator for use in a garbage incineration power plant includes: a furnace body, a feeding trough, and a grate. The lower part of the furnace body is a combustion area, and the grate is arranged in the combustion area. The feeding trough is located outside the combustion area of the furnace body and is connected to the furnace body. A hopper is arranged above the feeding trough, and two crushing rollers are arranged at the bottom of the hopper. The front section of the grate is located below the feeding trough, and a plurality of air hoppers are arranged on the lower side of the grate, and air is conveyed into the air hoppers through a blower. A slag discharge channel is arranged at the end of the grate. A ventilation pipe is arranged on the inner wall of the furnace body opposite to the grate, and the ventilation pipe blows hot air obliquely upward to the grate.

[0007] Preferably, a reciprocating push plate is arranged at the bottom of the feeding trough, and upwardly inclined and evenly spaced convex platforms are arranged on the upper side of the push plate.

[0008] Preferably, an auxiliary material pipe is arranged above the hopper, and the auxiliary material pipe conveys coal blocks to the hopper.

[0009] Preferably, fixed grate plates and movable grate plates are adopted on the grate. The fixed grate plates are fixed on the grate frame, and the movable grate plates are pushed by a driving device to make reciprocating movements on the grate frame. The fixed grate plates and the movable grate plates are arranged alternately, and both the fixed grate plates and the movable grate plates are arc-shaped plates.

[0010] Advantageous Effects:

[0011] 1. In the utility model, two crushing rollers are provided at the bottom of the hopper above the feed chute, which can crush the garbage in advance, increase the surface area of the garbage, and make the combustion more complete. In addition, the ventilation pipe blows secondary air to the grate, ensuring sufficient oxygen supply in the combustion area, and the blown air is hot air, avoiding the reduction of the temperature in the furnace body and further promoting the complete combustion of the garbage;

[0012] 2. Outside the furnace body, the reciprocating push plate at the bottom of the feed chute and the design of the convex platform on its upper side make the feeding more uniform and stable, reducing the unstable combustion phenomenon caused by uneven feeding. The design of the auxiliary material pipe for conveying coal blocks to the hopper can add auxiliary fuel when necessary to ensure the stability of combustion;

[0013] 3. The staggered arrangement of the movable grate bars and the fixed grate bars and the design of their arc-shaped pieces are not only conducive to the turning and full combustion of the garbage, but also facilitate the removal of furnace slag. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the utility model, the following further detailed description of the utility model is made in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 3 shown, a garbage treatment incinerator for a waste incineration power plant includes: a furnace body 1, a feed chute 4, and a grate 7. The lower part of the furnace body 1 is a combustion area 2, and a grate 7 is provided in the combustion area 2. The feed chute 4 is located outside the combustion area 2 of the furnace body 1 and is connected to the furnace body 1. A hopper 3 is provided above the feed chute 4, and two crushing rollers 6 are provided at the bottom of the hopper 3.
