Description
Technical field
The present invention relates to the treatment unit of a kind of waste residue or waste liquid, relate in particular to the device that a kind of a large amount of waste lyes that dye industry is produced are handled in producing the bipseudoindoxyl dye process.
Background technology
In medicine, chemical industry, DYE PRODUCTION process, often be attended by the generation of a large amount of alkali wastes, waste residue, if do not handle, recycle, can cause great pollution to environment.
At present, dye industry fine with anilino second be to produce a large amount of slag inclusion waste lyes in the indigo process of raw material production.Owing to still there is not the device of this waste lye of special disposal, remove the total alkali concn of few part in this waste lye and be 42% waste liquid and can sell little paper mill and use, other most of alkali lye all is to lean on to be discharged into secondary liquid waste disposal station after diluting.Contain a large amount of poisonous, objectionable impurities in this waste liquid, have only paper mill seldom to be ready to buy; Directly this discharging of waste liquid is seriously endangered environment on the one hand, a large amount of on the other hand salkali waste can not be recycled, and causes serious waste.
Summary of the invention
The object of the present invention is to provide a kind of device that can handle alkali waste/slag.
The objective of the invention is to realize like this: the treatment unit of waste liquid/slag is characterized in that: this device comprises spraying absorption reactor thermally and the high temperature cabonization reaction unit that connects through pipeline A.
In order to make full use of the heat that device produces, this device also comprises cyclonic separator and interchanger, and said cyclonic separator links to each other through pipeline B with said spraying absorption reactor thermally, and said interchanger links to each other through pipeline C with said cyclonic separator.The principle of work of said cyclonic separator and interchanger is: the waste heat in the absorption reactor thermally of at first will spraying is delivered in the cyclonic separator and purifies, and entrainment in the hot gas flow is reclaimed; And then the hot gas flow after purifying in the cyclonic separator is delivered in the interchanger, heat is delivered in the liquid in the interchanger, carry out preheating.
Spraying absorption reactor thermally of the present invention is a spray-dryer, it is characterized in that: in the liquor inlet of said spraying absorption reactor thermally, be provided with the high speed centrifugation atomizer.The contriver utilizes the effect that reacts to each other between the material; Spray-dryer is used as reactor drum; Both had functions/drying, carried out initial reaction again simultaneously the slag inclusion waste liquid, when the slag inclusion waste liquid when liquor inlet gets into the spraying absorption reactor thermally; Through the inside cavity that high speed centrifugation atomizer atomizing back gets into said spraying absorption reactor thermally, the carbonic acid gas that sends with pipeline A carries out initial reaction.
Said high temperature cabonization reaction unit can be selected rotary kiln or carburizing reagent stove as required.
Said rotary kiln carries out work by counter-current principle, and the kiln body has certain obliquity usually, is generally 2%～3%; Fuel and combustion air are gone into kiln by a lower end, and material then adds from higher kiln tail end, and material and hot gas flow be motion in the opposite direction in kiln; When the kiln body rotates, just take material to certain altitude, under the effect of gravity, material falls along the inclined-plane again then; Because the kiln body has certain obliquity, when material rises and falls, just to the kiln hood direction certain distance that advances, until kiln hood, the roasting reaction process of completion material.
In order to make full use of the heat in the rotary kiln, can outside the kiln hood of said rotary kiln, be provided with vaporizer, accomplish follow-up product crystallization and purification process.
Said carburizing reagent stove is the intermittent type high temperature cabonization reaction unit that the contriver designs, and comprises the burner and material pond that connect through flame hole; Said burner is provided with fuel inlet; Upper edge, the side heat conduct route in said material pond is provided with bin gate.The principle of work of said carburizing reagent stove is: in burner, inject fuel, heat that fuel combustion produces and gas get into the material pond through flame hole, react with the waste liquid/slag that enters into the material pond.
For the hot gas flow that makes flame hole come out faces toward the material in the material pond, the effect of imitation frosted glass is better, and an end of the said burner of connection of said flame hole is a little more than an end that connects said material pond; The indoor planar height in said material pond is higher than the height of grate a little less than the height of said flame hole.
For the heat radiation back reflection is returned, guarantee the high insulating effect of carburizing reagent stove, the top in said burner and said material pond is arch.
Work for ease, said burner is provided with porthole; Said bin gate is 3～5.
In order to be that the fuel combustion of burner is better, the bottom of said burner is provided with blower fan.
The basic functional principle of apparatus of the present invention is following:

The transmission route of the waste liquid/slag in apparatus of the present invention is:
At first slag inclusion waste liquid entering interchanger carries out thermal pretreatment; The slag inclusion waste liquid that comes out from interchanger gets into the spraying absorption reactor thermally; The slag inclusion waste liquid gets into the inside of spraying absorption reactor thermally and carries out initial reaction after the atomizing of high speed centrifugation atomizer in the spraying absorption reactor thermally; The carbonic acid gas that part sodium hydroxide in the slag inclusion waste liquid and Pottasium Hydroxide and pipe-line transportation are come is reacted yellow soda ash and salt of wormwood at high temperature; The material that comes out the absorption reactor thermally from spraying gets in carburizing reagent stove or the rotary kiln and carries out end reaction, in the material still the intact sodium hydroxide of unreacted continue with Pottasium Hydroxide and carbonic acid gas at high temperature reacted yellow soda ash and salt of wormwood; Organism in the slag inclusion waste liquid and oxygen at high temperature react and generate carbonic acid gas, nitrogen G&W;
The heat in apparatus of the present invention and the transfer route of gas are:
Produce great amount of heat and carbonic acid gas in burner or the kiln hood in the combustion processes of fuel, get into material pond or kiln body, and then get into successively in spray reaction moisture eliminator, cyclonic separator and the interchanger through pipeline; In heat transfer process, being accompanied by series of physical changes and chemical reaction; Last gas is discharged from the flue gas suction opening, and the water of condensation that water vapor condensation becomes is discharged from the condensation mouth of a river.
