The specific embodiment
Shown in accompanying drawing 1-4, a kind of potassium chloride dry products cooling bed of the present utility model, this fluid bed is built-in with water cycle heat exchange cooling water pipe 2 and built-in fiber bag precipitator 1, and the fluid bed sidewall is provided with charging aperture 3, bottom and is provided with air inlet 4, air compartment 5, fluid bed bottom and material leak-proof air distribution plate 7 and discharge gate 8, fluid bed top are installed are provided with air outlet 6 and form.
Described built-in fiber bag precipitator 1 is to filter combining structure by pulse of air injection system and dust to constitute.
Described dust filters combining structure and comprises that fiber bag precipitator, framework, venturi winding-up pipe constitute.
Described built-in fiber bag precipitator 1 adopts tower structure.
Operation principle: from the high-temperature material continuous distributed of drying operation on the material leak-proof air distribution plate 7 of fluid bed inside, air is by after the homogenization of material leak-proof air distribution plate 7, be upward through material on the material leak-proof air distribution plate 7, material is carried low suspension secretly in air-flow wind, boiling water just as boiling, under the effect of bubble, violent seething beated, material particles evenly fully contacts with air-flow under the irregular movement state, produce intensive impact and in this process, carry out ferocious heat and mass effect on built-in heat exchange cooling water pipe 2 surfaces simultaneously, finish cooling procedure.Whole materials after the process cooling processing are in the discharging of fluid bed discharge gate.
Design feature
Fluid bed design has taken into full account the characteristics of material, i.e. material good dispersion, and dried material has only the minority large granular materials, and material does not have thermal sensitivity substantially, and amount of cooling water is big.The design feature of design is as follows: adopt special cloth wind structure, avoided that general fluid bed occurs because air distribution plate leaks loss of material, pollution, the obstruction air compartment that material causes, simultaneously can with larger particles rapidly row to discharge end so that material fluidisation phenomenon not.Different fluidizing velocities is adopted in segmentation, the not fluidisation phenomenon of having avoided general fluid bed feeding section to occur.All material is discharged from fluid bed discharge gate 8, has reduced Dust Capacity and conveying equipment, has also reduced the discharging point simultaneously, has lowered operation labour intensity.Cool time is adjustable, need to be specially adapted to the material of degree of depth cooling.Buffer capacity is strong, product with stable quality, and the stable control of energy realization system has more buffering material in the fluid bed, can effectively avoid the production of defective material.The heat and mass ability is strong, and material contacts with air evenly, can effectively avoid hot nest (solid accumulation drying/cooling less than) phenomenon.Built-in heat exchange cooling water pipe 2, most of cooling heat is provided by cooling water, because the temperature of cooling water is lower than air themperature in summer, can also can guarantee cooled temperature of charge in summer, reduced the air through put amount simultaneously, reduce the air-treatment amount in the dust removal process, significantly reduced the investment in deduster, main process equipment, airduct road, reduced power consumption simultaneously.Main frame adopts built-in fiber bag precipitator 1 mode, and cooling and dust removal process realize that in same equipment the efficiency of dust collection height has effectively reduced equipment investment.Built-in fiber bag precipitator 1 is to play the effect that replaces enlarging segregation section simultaneously after the expansion segregation section with conventional fluid bed removes.Mainly consisting of of built-in fiber bag precipitator 1: the pulse of air injection system, dust filters combining structure.The effect of pulse of air injection system is to bring fiber bag precipitator 1 into by near mouthful a large amount of air of will jetting under the compressed-air actuated injection of high-voltage high-speed, the dust that oppositely will stick to fiber bag precipitator 1 surface blows off, thereby makes fiber bag precipitator 1 and dust separation.To remove the filter bag dust stratification, make fiber bag precipitator efficient keep constant, dust filters combining structure and comprises fiber bag precipitator, framework, venturi winding-up pipe etc., its effect is by himself micropore of fiber bag precipitator 1 air to be seen through, and dust granules micropore only thoroughly, thereby play the effect that separates dust.Clear dirt is effective, does not damage cloth bag, it has, and purification efficiency height, treating capacity are big, stable performance, long service life excellent outside, the performance that also possesses skills height, the characteristics of applied range.Compliance with environmental protection requirements, the efficiency of dust collection height.
Main frame freedom from repairs, service life of equipment are far longer than other form drying equipments, because main frame does not have running gear, except that feeder, other equipment are permanent plant, so freedom from repairs, goods fluid speed is extremely low, and is little to equipment attrition.By rational system configuration, the automatic or semi-automatic operation of feasible system.The reasonably setting of cleaning eye, observation visor can be satisfied the equipment operation and detect.
In establish the quickly discharging structure, can be in running as much as possible presumable big fast granule materials be discharged rapidly, guaranteed the equipment operational reliability, the built-in discharging structure of body is a particular design, can satisfy the discharging requirement, guarantees not stuck.The discharger rotating speed adopts fixed and frequency control is regulated.
Built-in fiber bag precipitator 1 adopts frame structure, does not need repairing.Equipment material material leak-proof air distribution plate 7 parts are stainless steel.
