Abstract
A three-in-one fluidized bed dryer for preparing salt and other materials with similar physical properties features that it integrates the heating in stirring bed and the cooling in bed, its bed body is composed of wind box and fluidizing box, the fluidizing segment of fluidizing box is divided into drying segment and cooling segment by partition plate, the material is fed into drying segment from front end of bed and fed into cooling segment from the channel between partition plate and wind distributing plate, and then discharged from overflow port to discharge port.
Description
The utility model relates to a kind of industrial fluidized bed drier, definitely says a kind of novel three-in-one fluidized bed dryer that relates to the close dry materials of salt manufacturing transitivity.
Salt industry at present in the subject matter with drier is: common fluid bed and vibrated fluidized bed, bed surface is long-pending greatly, gas consumption is big, the steam consumption is high, power consumption is high, occupation of land is wide, self and related investment are big.The Nei Renei cold bed of foreign country, though gas consumption is little, the steam consumption is low, power consumption is lower, occupation of land is few, but this device requires highly to the wet feed state etc. of containing that enters material, controls such as supporting dehydration equipment, slurry concentration, flow is required high, is implementing relatively difficulty under domestic enterprise's condition at present.
The purpose of this utility model is: design and develop that a kind of volume is little, gas consumption is little, the steam consumption is low, power consumption is low, take up an area of less and require lowly wet contain etc. to going into a material, dehydration equipment, slurry concentration, flow-control are required novel three-in-one body fluidized bed dryer low, that self and related investment are economized.
The utility model by bellows, fluidisation case, charging aperture, agitator, bed internal heater, bed intercooler, discharge valve, discharge gate, air distribution plate, hot air inlet, advance parts such as cold wind mouth, exhaust outlet and form.Bellows are made of hot blast chamber, cold air chamber, and its effect is to make the cloth wind pressure uniform and stable.From the material inlet to the outlet, whole fluidisation case is divided into dryer section and cooling section, is provided with dividing plate between two sections, and is at regular intervals between its lower end and the air distribution plate.The dryer section of fluidisation case is carried out heat drying to material, and cooling section cools off material.The other effect of fluidisation case is in the fluidisation section material to be carried out fluidisation, for dry or cooling provide necessary condition, treats out the separation and the recovery of tailstock gas medium silt at segregation section, and necessary space is provided.Agitator places the feed end of fluidisation case inner drying section, and it is by variable speed drive and stir rake and forms, effect be utilize stir rake will go into bed material group drying up in its surface thousand before, it is broken diffusing, for the fluidisation of feed end place material is given security.After the bed internal heater placed the dryer section agitator, the bed intercooler placed cooling section.Heat exchanger (heater or cooler) is formed by parts such as heat exchanger tubes in the bed, is supported on the carriage, is installed in the fluidisation section and also can advances extraction.The bed internal heater feeds steam and by heat exchanger tube heat drying material, the bed intercooler is by cooling water and by heat exchanger tube cooling material.Discharge valve is made up of valve plate and handle, be used for and discharge intermittence by manually from big (piece) grain material that overfall is discharged, between bellows and fluidisation case air distribution plate being set, matches with the dryer section of fluidisation case in the hot blast chamber of bellows, and cold air chamber matches with cooling section.The effect of air distribution plate is that the wind in the air compartment is distributed into the fluidisation section uniformly.
The dry run of material in drier is performed such: material is gone into drier with bulk from charging aperture, under stirring, agitator is in the fluidisation attitude, and suck the heat of the hot-air that comes the hot blast chamber and be heated drying, with the fluidisation attitude heater dryer section that enters bed, the common heating of the hot-air that comes through this heater and hot blast chamber, dry after with the fluidisation attitude cooler cooling section that enters bed from the dividing plate lower end, after the common cooling of the cold air that cooler and cold air chamber come, go into discharge gate through overfall and discharge.Large granular materials in the drier manually intermittently enters discharge gate by discharge valve and discharges.Cold and hot wind enters hot and cold air compartment respectively from hot and cold air port, and it is even through air distribution plate, enter fluidisation section fluidisation material, hot blast heat release dried material in the fluidized drying section also carries the moisture content that material transmits, cold wind absorbs heat in the fluidisation cooling section and cools off material, go out tail gas from the fluidisation section behind segregation section separating most powder, discharge from two tail gas outlets, and enter subsequent processes.
The utility model has been compared following improvement and innovation with foreign same category of device:
Improve: charging is the charging of bed front end face in the middle part of 1, changing in the fluid bed, and it is overheated to have eliminated its front end material, has guaranteed product quality, has improved the drying efficiency of fluid bed, has reduced the charging aperture height factory building flooring absolute altitude relevant with it.
2, change electronic continuous pulp discharge for manually intermittently arranging the bulky grain material, reduce power consumption and cost.
3, the hot stringing of companion of the dry segregation section of cancellation and hot blast septum of ventricles of heart plate reduce hear rate and cost.
Innovation: 1, invented the fluidized bed dryer that collects the three-in-one body of cooling in heating in stirring, the bed, the bed.
2, set up agitator at feed end, with adapt to bulk and than high humidity contain material (the many desk centrifuges of China be equipped with belt be delivered into the bed material be so) and flow frequently and significantly change, reduced strict demand, handled easily to feed state.
Good effect of the present utility model is: long-pending lower by 70% than the common fluid bed bed surface that does not have heat exchanger in the bed, deduster and airduct are directly through reducing 45%, joint vapour 30%, economize on electricity 60%; Compare with the foreign similar fluid bed that an interior heat exchanger is arranged, bed surface is long-pending to increase 20%, interior heat exchange area reduces 18.6%, there is not the anti-hot heat-transfer surface of expose, deduster is close with the airduct equal diameter, plant area is close, the steam consumption is also close, but economize on electricity 25%, the bulk material that foreign fluid bed only allows to join the separate unit centrifuge advances bed, and centrifuge charging solid-to-liquid ratio and the basicly stable coupling of traffic requirement, and the utility model does not have this harsh charging requirement by means of agitator, operating flexibility is bigger, and the operational reliability height can carry out the economic adjustment steam consumption and material temperature according to each temperature in the bed with by heat exchanger.
The utility model has following accompanying drawing:
Fig. 1 is three-in-one fluidized bed dryer front view.
Fig. 2 is the A-A cross sectional plan view of Fig. 1.
Mark among the figure: 1 is bellows, and 2 is visor, and 3 is charging aperture, 4 is agitator, and 5 is exhaust outlet, and 6 is the bed internal heater, 7 is the fluidisation case, and 8 is discharge valve, and 9 is discharge gate, 10 is hand-hole, and 11 is air distribution plate, and 12 is the hot blast import, 13 is dividing plate, and 14 is weir plate, and 15 is the cold wind import, 16 are the admission bag, and 17 are the water outlet bag, and 18 is the bed intercooler.
