Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration equipment, and more specifically, to a garbage incineration grate. Background Art

[0002] The grate is a component in a boiler or industrial furnace that stacks solid fuel and enables it to burn effectively. Currently, waste incineration is one of the main ways to treat urban domestic waste. Waste incineration can achieve waste reduction, harmlessness and resource processing. At the same time, it can eliminate various pathogens, convert harmful substances into harmless substances, and realize resource utilization. The existing waste incineration generally includes a feed inlet, a waste incineration grate, an air supply system, and a slag discharge port. The garbage is burned on the grate. The existing grates are divided into block grates and rod grates.

[0003] The existing announcement number is CN217274161U, and the name is a garbage incineration grate, including a plurality of grate units arranged in a stepped manner from high to low, the grate unit including a plurality of grate arrangement blocks, the grate arrangement blocks are in the shape of long strips, the grate arrangement blocks are arranged in parallel, and a plurality of ventilation holes are provided on the grate arrangement blocks on both sides of the grate unit. The garbage on the furnace walls on both sides is easy to accumulate and not easy to loosen, and the amount of oxygen entering is small. Therefore, the garbage close to the furnace walls on both sides is burned due to lack of oxygen, forming a reducing atmosphere, which leads to serious coking. By using this scheme, a plurality of ventilation holes are provided on the grate arrangement blocks on both sides of the grate unit, and the ventilation holes of the overlapping parts of the grate units are interconnected. The grate air under the garbage incineration grate can enter the combustion area through the ventilation holes, providing sufficient oxygen, so that the garbage close to the furnace walls on both sides is fully burned, and the ash melting and coking caused by the lack of oxygen combustion is prevented, which can effectively solve the coking problem on both sides of the incineration grate.

[0004] However, when the garbage accumulated on the above-mentioned grate is burned, there is a lack of a turning device on the grate. The grate air is supplied through the surface air supply holes. The burning garbage has sufficient air supply at the bottom and burns more completely. The burned slag will block the air supply holes. Due to the lack of a turning device, the garbage on the upper part of the grate receives less air, resulting in incomplete combustion of the garbage above and below the grate. Utility Model Content
