The invention discloses a collaborative incineration system and technology for sludge with a low heat value and edible fungus dregs. The incineration system sequentially comprises a feeding treating system, a storing and conveying system, an incineration and waste heat boiler system and a turbine power generation system; the incineration and waste heat boiler system comprises an incinerator and a waste heat boiler, wherein the incinerator is composed of multiple layers of grate furnaces on the upper portion and a fluidized bed on the lower portion; and the turbine power generation system comprises a back pressure type turbine and a steam pipeline, wherein the steam pipeline is heated by the waste heat boiler. The collaborative incineration system and technology for the sludge with the low heat value and the edible fungus dregs have the following advantages that the incinerator combines the advantages of multiple layers of the grate furnaces and the fluidized bed, and therefore the heat utilization efficiency is greatly improved; the wet sludge with the low heat value is collaboratively treated by means of the waste edible fungus dregs with a high heat value, and therefore the purpose of treating waste with another waste is achieved; combined heat and power generation is conducted through a back pressure type turbine unit, and therefore heat is efficiently utilized; the whole system does not need additional fuel, and therefore self-maintaining incineration and external heat supply are achieved.

The invention belongs to the field of waste incineration devices and particularly relates to an incinerator with a fixed fire grate. The incinerator with the fixed fire grate is used for incinerating biomass materials such as straws and at least comprises a main combustion chamber, an air supply assembly and a smoke flue for guiding heat energy in the main combustion chamber out. The main combustion chamber is communicated with the smoke flue through a ventilation pipe, and a conveying and incinerating platform is arranged in the main combustion chamber and at least comprises a bearing plate and a stirring portion. The incinerator with the fixed fire grate further comprises a pushing portion, wherein an air return moisture removal cavity channel is arranged between the pushing portion and the main combustion chamber in a transition mode and forms a material conveying path for connecting the cavity of the main combustion chamber with the pushing portion, an air outlet is formed in the end of the air return moisture removal cavity channel and communicated with an external air draught fan, and the end of the air return moisture removal cavity channel and the pushing portion are positioned at the same end. The incinerator with the fixed fire grate is high in operation reliability and incineration efficiency, low in cost and capable of ensuring incineration at high and constant temperature and extracting and utilizing efficient heat energy of biomass fuel.

The invention relates to an energy conservation and emission reduction system, and discloses an environment-friendly type energy conservation and emission reduction system. An incinerator of the environment-friendly type energy conservation and emission reduction system comprises a pretreatment chamber and an incineration chamber. The pretreatment chamber is sequentially divided into a large-particle trash chamber, a dust trash chamber and a water storage chamber from top to bottom. The incineration chamber comprises an incineration cavity and a fuel cavity. The incineration cavity is dividedinto a large particle incineration cavity and a dust incineration cavity. A stirring and smashing paddle is arranged in the incineration cavity. An induced draft fan communicating with the dust trashchamber and the dust incineration cavity is arranged on the side wall of the dust trash chamber. A trash smashing device comprises a roller and crushing bodies distributed on the left side and the right side of the roller correspondingly. Each crushing body comprises a crushing block used in cooperation with the outer side wall of the roller for conducting trash crushing. The width of a trash crushing cavity is gradually decreased from top to bottom. According to the environment-friendly type energy conservation and emission reduction system, by means of the structural design of the incinerator and the trash smashing device, the incineration efficiency and the incineration sufficiency can be increased to a great extent, the incineration time can be sufficiently shortened, the fuel consumption and the slag discharge amount can be reduced, and the effects of energy conservation and emission reduction can be achieved.
