Description
Technical field
The invention belongs to industrial production technology field, particularly relate to the drying materials treatment system that a kind of material larger to moisture content is dried.
Background technology
In industrial processes, the material that moisture content is larger generally all will use dryer equipment in dehydration link, and dryer equipment is divided into industrial stoving equipment and civilian drying plant.
Industrial stoving equipment belongs to mining machinery, mostly generally is large and medium-sized machinery, and its thermal source, from burner, adopts downflow type mode of heating.Therefore need the material of drying, slip into into cylindrical shell from material feeding box, charging, after namely being pushed to by spiral flight.Due to dryer slant setting, material on the one hand gravity and gyroscopic action to the back-end dirty, material is taken up repeatedly by flight on the other hand, bring to upper end constantly to raise again and spread, make material in cylinder, form uniform curtain, the thermal current fully and in cylinder carries out heat exchange, repeatedly raises spread due to material, contained moisture is dried gradually, thus reaches the object of oven dry.
Civilian drying plant belongs to washing machine, generally after rinse dehydration, is used for removing the moisture in clothes and other textiles.Most dryer comprises a cylinder rotated, and inner core by belt drives, has hot-air to be used for transpiring moisture around cylinder.Drying is all the principle adopting cylinder rotating, what reach drying article is not wound around effect, and early stage dryer has been eliminated now substantially, and modern oven dry adopts computer automatically to control, according to drying requirement, different bake out temperatures and drying time can be configured.Cylinder adopts the stainless steel bright plate of excellent heat resistance to be made, and inner wall smooth, can reduce the wearing and tearing of clothing.High-efficiency radiator, and be equipped with rational wind channel, makes hot blast directly and contact with clothing, substantially increases drying efficiency, save the energy simultaneously.Major diameter feeding mouth, facilitates into and out of clothing.Large-area lint collecting net, is not easy to cause lint to block, protects the unimpeded of air channel, thus greatly improve drying efficiency.
Industrial stoving machine equipment is widely used in the industries such as mine, building materials, highway, bridge, coal, metallurgy, chemical industry, resistance to material.Be mainly used in moist large, the heavy materials such as slag, lime stone, clay, river sand, quartz sand, grain slag.
The particular type of industrial stoving machine equipment comprises: industrial drier, sludge dryer, coal slurry drying-machine, horizontal drying machine, three-cylinder drier, iron powder dryer, excrement class dryer, foodstuff drying device, desulfurated plaster dryer, slag drying machine, quartz sand dryer, rotary drum drying machine, roller drying machine, brown coal dryer, tower drier etc.
Industrial stoving equipment possesses following three indexs at the function needs meeting drying and processing:
One, gross efficiency: also can be described as average efficiency, the i.e. Dust Capacity of dryer removing in the same time and the percentage of the Dust Capacity flowed into from dryer import.Two, percent of pass: percent of pass refers to the percentage of dryer outlet Dust Capacity and import Dust Capacity.Percent of pass is larger, and illustrate from the Dust Capacity of dryer outlet larger, namely drying efficiency is lower.In addition, when the drying efficiency of dryer is very high, represent that difference in dryer performance is than more obvious when representing by gross efficiency with percent of pass.Three, classification drying efficiency: the dryer efficiency that classification drying efficiency is demarcated by dust size or particle size range is called classification efficiency, and it refers in a certain particle size range, the ratio of the Dust Capacity be captured and import dust total amount.The oven dry gross efficiency of dryer and the particle diameter of processed dust have much relations, even same device works under same service condition, due to the difference of dust dispersity, the performance of dryer also has significant difference.
Various industrial material drying plant while meeting above-mentioned three important indicators as far as possible above, defects such as there is complex structure to some extent, program is loaded down with trivial details, cost is high, drying and processing efficiency is low, drying effect is bad, dust pollution is large, use cost is high.
