Description
Technical field
The invention belongs to the technical field that desulfuration byproduct is processed, be specifically related to a kind of sulphur mud, sulphur cream conversion system and conversion process.
Background technology
Sulphur exists with three kinds of forms in coal, i.e. organosulfur, sulfurous iron ore sulphur (sulphur that the form such as pyrite and white pyrite sulphur exists) and sulfate sulfur.The heat release though sulphur can burn, it is the composition being very harmful to.After combustion of sulfur, generating sulfurous gas (SO2) and a small amount of sulphur trioxide (SO3), enter atmosphere energy contaminate environment, is the essential substance that forms acid rain, all harmful to human body and animals and plants and above ground structure.For reducing above harm, coke-oven plant, fertilizer plant etc. uses coal rich and influential family, with all fire coal being carried out to desulfurization before coal.
At present, domestic many coke-oven plants adopt take the sulfur removal technology that ammonia is alkali source, and the sulfur removing pregnant solution that this technique belongs to after wet desulphurization ， desulfurization workshop section absorbing hydrogen sulphide produces sulphur foam in regenerative process, and this sulphur foam show bubble, is a kind of solidliquid mixture.A lot of coal chemical enterprises are all after taking the method for centrifuge dripping to dewater, the sulphur mud of the certain water content finally obtaining or sulphur cream.Solids in sulphur mud or sulphur cream is mainly sulfur granule, also contains a small amount of coloured oily organic impurity.Sulphur is a kind of important chemical raw material, but because contained sulfur purity in sulphur mud or sulphur cream is not high, is difficult to purify and processing.Therefore, the value of sulphur mud, sulphur cream is not high, is mainly used as solid waste disposal.General treatment process is to stack landfill or take-away, and these sulphur mud, sulphur cream are deposited in and will cause environmental pollution outward, are also a kind of wastings of resources simultaneously; Take out that economic benefit is low, and buyer refines sulfur waste sulphur by heating, consume coal amount high, cause the wasting of resources.
Also the technique that has pair sulphur mud, sulphur cream to recycle in prior art to utilize: (1) take the distil process that steam or flue gas are thermal source, and this technique is owing to having ignored coloured organic impurity in solid, and the sulfur purity of gained is not high, and utility value is not high; (2) adopt the sulphur in extraction process recovery and purification sulphur mud, sulphur cream, this processing step is complicated, and production cost is high, and the productive rate of gained sulphur is low; (3) sulfur melting kettle sulfur-melting technology, this technique is that sulphur mud, sulphur cream are added in sulfur melting kettle, and the sulphur in sulphur mud, sulphur cream is all molten into liquid, the energy consumption of this technique in molten sulphur process is excessive, greatly increases production cost.
The harmless treatment of sulphur mud, sulphur cream is the important component part of desulfurization recycle section.Seen from the above description, the byproducts such as the sulphur mud of producing after desulfurization from fire coal, sulphur cream, sulfur purity is low, of poor quality, sale is difficult, except boiling the sulphur of low-purity, does not also have at present other reasonable methods to be used.
Summary of the invention
The object of the invention is to for the defect of above-mentioned existence and a kind of sulphur mud, sulphur cream conversion system and conversion process are provided.This treatment process is simple, and production cost is low, can make full use of to greatest extent sulphur mud, sulphur cream.
Technical scheme of the present invention is: a kind of sulphur mud, sulphur cream conversion system, and the base support that comprises housing and be welded in lower housing portion, has furnace gas export at the end face of housing; Opening for feed is arranged at housing feed end top, and opening for feed place is provided with feeder; Slag outlet is arranged at housing slag output end bottom, and slag exit is provided with water seal arrangement; Housing bottom surface is inclined-plane, on this housing bottom surface, arranges and is fixed with fixed grate film step by step, is provided with air compartment below fixed grate film, and air compartment is provided with inlet valve; Between two adjacent fixed grate films of described fixed grate film, be provided with movable furnace grate plate, this movable furnace grate plate is fixed on adjustable shelf, described adjustable shelf be positioned at housing bottom surface under; Described adjustable shelf bottom is provided with several resting supports, and resting support bottom joins by pulley and the slide rail being fixed on base support; Described resting support connection for transmission device; Described enclosure interior is provided with waste heat recovery unit.
