Problems solved by technology

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, resulting in bacterial reproduction and disease transmission.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] as attached figure 1 The low calorific value sludge and edible fungus slag co-incineration system shown, from front to back, includes the pretreatment of edible fungus slag and the feed treatment system for mixing edible fungus slag and wet sludge, used for The storage and transportation system for the storage and transportation of edible fungus residue and wet sludge mixture, the incineration and waste heat boiler system for incinerating the mixture and recovering the heat of high-temperature furnace gas, and the back pressure steam turbine for power generation system.

[0024] The incineration and waste heat boiler system includes an incinerator 10 and a waste heat boiler 16 connected to the incinerator 10. The high temperature furnace gas generated by the incinerator 10 enters the waste heat boiler 16, and the waste heat boiler 16 recovers the heat of the hi...

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...
