With the development of society, the yield of municipal solid waste increases year by year, and how to treat a large amount of municipal solid waste becomes a problem which needs to be solved urgently. The municipal solid waste can be rapidly treated by burning the waste, and the volume of the waste can be effectively reduced. At present, the research and application of the waste incineration power generation technology become one of the major hot issues in the world, and are widely concerned by governments and scientific researchers in various countries in the world. Garbage is a resource which is huge in quantity and easy to neglect, and the power generation energy is recycled through incineration, so that the large-scale production and use of the garbage incineration technology are easier to realize, and the related garbage incineration power generation technology and equipment at home and abroad have partially realized industrial application. The waste incineration power generation can recycle the waste, reduce the coal power generation and protect the environment and resources. However, the existing garbage incinerators have some defects, especially in the aspect of combustion efficiency, because garbage is directly dumped into the incinerator from a feed port to form accumulation, the contact area is often too small, the combustion is insufficient, and the residues are too much.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a fixed sieve plate structure of a hearth of a garbage incinerator is characterized by comprising a furnace body 1, wherein a feed inlet 2 communicated with an inner cavity of the furnace body 1 is formed in one side of the top of the furnace body 1; the other side of the top of the furnace body 1 is provided with a smoke outlet 3 communicated with the inner cavity of the furnace body 1; a filter screen 4 is arranged at the joint of the smoke outlet 3 and the inner wall of the furnace body 1; a fixed sieve plate 5 is arranged on the inner wall of the furnace body 1; an air inlet pipeline 7 communicated with the inner cavity of the furnace body 1 is arranged on one side of the bottom of the furnace body 1, and the air inlet pipeline 7 is connected with the furnace body 1 and an air blower 8; a fire grate 6 connected with the inner wall of the furnace body 1 is arranged above the connection part of the air inlet pipeline 7 and the inner wall of the furnace body 1; an ignition port 9 is formed at the bottom of the furnace body 1; the middle of the bottom of the furnace body 1 is provided with a slag hole 10 communicated with the inner cavity of the furnace body 1.

Preferably, the fixed sieve plate 5 comprises an upper fixed sieve plate 51, a middle fixed sieve plate 52 and a lower fixed sieve plate 53, all of which are inclined downwards and form an included angle of 60 degrees with the inner wall of the furnace body 1, the upper fixed sieve plate 51 and the lower fixed sieve plate 53 are both arranged on the inner wall of the furnace body 1 right below the feed port 2, the middle fixed sieve plate 52 is arranged on the inner wall of the furnace body 1 opposite to the right below the feed port 2, and sieve holes 54 are arranged on the fixed sieve plate 5.

During actual operation, after the garbage enters the inner cavity of the furnace body 1 from the feeding hole 2 and passes through the fixed sieve plate 5, part of the garbage is intercepted on the fixed sieve plate 5, other garbage falls downwards along the gravity direction, the upper fixed sieve plate 51, the middle fixed sieve plate 52 and the lower fixed sieve plate 53 of the fixed sieve plate 5 perform spatial stratification on the garbage falling into the furnace body, the garbage which is not intercepted is finally scattered on the fire grate 6 for direct combustion, and the burning flame can ignite the garbage on the fixed sieve plate 5. After entering the inner cavity of the furnace body 1, the garbage is separated in a spatial layering way and a plurality of times through the fixed sieve plate 5, so that the contact area is increased, the garbage is more beneficial to combustion, and the combustion rate is improved. The sieve holes 54 on the fixed sieve plate 5 are not used for separating the garbage, but are used for intercepting part of the garbage passing through the fixed sieve plate 5 and timely removing the residues after the garbage is incinerated.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. It will be apparent to those skilled in the art that other embodiments can be made on the basis of the above description without any inventive step and still fall within the scope of the present invention.
