Description
Technical field
The utility model relates to a kind of mud material drying system, particularly a kind of drying system at fine size, mud material indirect that moisture is big.
Background technology
At present the moisture of technology remove to(for) fine size, mud material that moisture is big adopts the firepower dry technology more, promptly the hot flue gas of producing with hot-blast stove fire coal or coal gas and wet stock in drying machine directly mixing contact, be drying process based on convective heat exchange.The improper product super-dry that very easily causes of this technological operation makes product increase ash, reduces product quality; For inflammable, explosive material (as floatation clean coal, brown coal etc.), because hot flue gas is easily brought accidents such as naked light also can burn, blast into.
Existing firepower drying process is improving hot flue gas and the relative velocity between the material that is dried, to promote the convective heat exchange between gas, solid phase, improves drying efficiency, therefore needs to be equipped with powerful air-introduced machine; Because air velocity height, can carry the material of a large amount of micro-size fractions in the air-flow, enter atmosphere and cause environmental pollution, therefore also need be equipped with the cleaner of twice Purge gas in the drying process system, and attached transportation and water-tight equipment, making firepower drying process system complex, equipment is many, capital expenditure height, operational management and equipment maintenance cost height.
Summary of the invention
The purpose of this utility model is: overcome the weak point of mud material in adopting the firepower drying process big for moisture, fine size, and provide a cover to optimize drying technology process, make dry run safe and reliable, dry products is pollution-free, do not increase ash.This technological process operational management is simple, is the low environment-friendly dry drying process production line of capital expenditure.
For achieving the above object, the drying process of the mud material that the utility model is developed is: set up a cover based on the indirect thermal conduction, and with radiant heat transfer is the mud dry materials processing line of assisting, and---boiler, environment-friendly type are given novel helicoid screw dryer, the thermal medium conveying equipment of heat indirectly---pump, wet stock transportation feeding device, dried back product conveying unit are formed by the dry heat medium manufacturing apparatus.The thermal medium of boiler preparation can be deep fat, steam, hot water, and the utility model recommends first-selection to do the dry heat medium with hot water, because hot water is produced easily, operating safety factor is big, and is manageable, and the operation controlling unit is few, so operating cost and capital expenditure are all low.
The novel helicoid screw dryer of exploitation is the nucleus equipment in the drying process line, the supporting composition of spiral tubular axis that it is made up of jacket type cell body and helix tube group and hollow shaft, 1～4 spiral tubular axis can be set in the cell body, and the mutual arranged crosswise of adjacent helix tube axial screw pipe group, relatively revolution.In the drying operation, thermal medium is series flow in spiral tubular axis and cell body chuck, wet stock is at cell body chuck inner wall outside and helix tube between centers, rely on the rotation of spiral tubular axis to promote, the heat radiation heat of heat that the absorption equipment wall transmits while transporting and heating face adds thermal material, makes the moisture vaporization in the material, finish dry run, obtain dry products.In order to satisfy the demand of different dry amount, every drying machine is stacked mutually by 2 or 3 put series operation.
The technical characterictic of novel helicoid screw dryer is: the equipment surface that the mud material is contacted in dry run all is a heat-transfer area, therefore wet stock one touches equipment surface, promptly obtain the heat that equipment surface is transmitted, it is dry to make material moisture be heated vaporization, has overcome because of hydrophily makes material stick to equipment surface to cause the sticking wall problem that is difficult for drying.The rotation of helical axis is mixed fully material and is rolled, also has the relative rotation of the helix tube group of arranged crosswise, can realize mutual self-cleaning and broken mud lump material, thereby the material of equipment surface is brought in constant renewal in, therefore can obtain uniform dry products; Thermal medium series flow in cell body chuck and spiral tubular axis in the dry run is not walked the hot-fluid of short cut, circulate between boiler and drying machine heating and utilize the thermal loss that hot flue gas of no use causes as discharging waste gas in the drying operation of thermal medium of thermal medium; Drying machine cell body outer surface has been set up lagging facility, has reduced the equipment surface radiation loss; In the spiral tubular axis, be provided with the internal thread of different pitch, strengthened the flowing velocity of thermal medium, after simultaneously can also preventing the inside pipe wall fouling, reduce the heat transfer resistance of tube wall, improve the heat transfer coefficient and the heat utilization efficiency of hot water effectively, its system thermal efficiency can reach more than 85%, and the thermal efficiency of thermal medium can go more than 98%.
Hot window is set on the drying machine housing, makes to enter the air that carries water vapour in the drying machine and suitably heat, improve its dew-point temperature, prevent dewfall in the drying machine, reduce product quality.Because hot water is relatively gentleer as thermal medium, can not make the overheated ash that increases of product; The gas of equipment and material crossfire in the dry run does not carry the air-flow of dust, need not to be provided with cleaner, so helicoid screw dryer is a kind of environment-friendly type equipment.
