A low calorific value sludge and edible fungus residue co-incineration system and process

Abstract

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.

Description

technical field

[0001] The invention relates to the field of pollution control equipment, in particular to a system and process for synergistic incineration of low calorific value sludge and edible fungus residue. Background technique

[0002] my country has become the world's largest producer of edible fungi, accounting for 70% of the world's total output. A huge amount of edible fungus residue is produced every year, but a large amount of mushroom residue has not been treated effectively in an environmentally friendly manner. Random discarding causes a huge waste of agricultural resources and also deteriorates the surrounding environment, causing bacterial reproduction and disease transmission. Edible fungus residue is the culture medium waste left after harvesting products during the cultivation process of edible fungi. Slag contains a large amount of protein, cellulose and amino acids and other substances. At present, the reuse of fungus residues is mainly focused on b...
