The new technology of dryer and development -- dryer of KBDH dynamic vertical eq
From;  Author:Stand originally
At present domestic stock drying basically lies insufficiently at: (1) widespread presence hot waste loses big, thermal efficiency low, coal consumption is tall, give makings moisture to be controlled hard, opposite yield is low problem; (2) the more than hot flue gas that is less than 350 ℃ to temperature cannot suit as stock of heat source drying; (3) cannot get used to the drying that contains crystallization water stock (if 2 water gesso becomes) of drying of half water gesso, cannot get used to the drying of high-moisture stock; (4) the phenomenon that greatens to stock cohere granuality appearing in stoving process is inextricability, great affected stock drying result; (5) stoving system did not use automatic personal computer to detect control system, cannot wait in time to makings, wind, coal have accurate land online detect and control, bring about stoving system to cannot produce optimal result. The newest generation KBDH that machinery of Jiangsu division treasure makes limited company develop is dynamic the cooperative project that vertical dryer equipment is its and southeast university, the patent product KBH that is in a company is improved on efficient vertical dryer and come, it is aimed at the inadequacy of equipment of current domestic and international drying and technological process, used new technology, new equipment and computer software technology, built stoving system to digitlize design aprametric model, energy-saving fall bad news is more apparent, coal consumption is drier of T of / of 8kg mark coal only, power consumption is drier of / T of 2 ~ 2.5kWh only, it is newer, stronger, have high yield more the dryer of new generation vertical of energy-saving effect.
The crucial technology of dryer of vertical of new generation trends is to make stock can disperse as far as possible inside dryer, accumulate in order to raise hot flue gas and stock interface, control stock at the same time in dryer each area velocity of flow is mixed retention period, make hot flue gas and stock sufficient convection, radiate, conduct heat exchange. We still will use stock drying parameter to optimize technology of personal computer software, belt, stoving belt, dry to warm-up belt gentle body temperature has the stock moisture content of 3 area online detect, right heat addition ability of the system, bring 2 wind force, sirocco to distributing reach discharge of cut of heat addition ability, stock and retention period to wait for systematic parameter to undertake online adjust, the trends that implements a system optimizes a balance, raise utilization rate of systematic heat energy.
This drying equipment included dust catcher of type of bag of pulse of box of efficient vertical dryer, gas, high temperature boiling furnace, and among them main facility or vertical dryer, this equipment innovates further by dryer of KBH efficient vertical and come. The place of innovation basically is in the following respects: (1) the stoving principle that applied efficient vertical dryer and method, use stock balance and hot balance principle at the same time, reservation is exterior heat preservation of simplified and quiet style, the high yield that the design installs unit of inside hot trade to be able to get used to different property stock is concentrated hot trade unit, used dynamic vertical dryer respectively prevent stock of regulating unit of an oscillatory cloth device, oscillatory discharge, circumgyrate broken unit, inside and outside is annular the device that take wind, solved thoroughly jam problem; (2) 2 sirocco technology and structure; (3) change diameter structure, cement industry rotary kiln does law product line to produce a large number of temperature the more than hot flue gas under 350 ℃ , of these more than hot waste gas use to reducing specific power consumption, reduce manufacturing cost to have crucial effect. Before, because the blemish of circumgyrate dryer itself is right,more than heat cannot use this part effectively, and dryer of dynamic and efficient vertical through changing diameter structure makes warm-up belt, drying takes a diameter to expand, wind speed is reduced, evaporate the space greatens, the awl of comb with a double-edged fine-toothed comb of basin of comb with a double-edged fine-toothed comb that adopts different form at the same time dominates the retention period of stock, develop the biggest efficiency of utilization of waste heat; (4) belt, stoving belt, dry to warm-up area is passed in stoving testing system gentle body temperature has the stock moisture content of 3 area online detect, self-poise controls systematic makings, wind, coal, right heat addition ability of the system, bring 2 wind force, sirocco to distributing reach discharge of cut of heat addition ability, stock and retention period to wait for systematic parameter to undertake online adjust, optimize a balance in order to realize craft parameter trends of the system, raise the utilization rate of systematic heat energy. Innovate through above, new stoving facility needs what can get used to vast enterprise more actually surely.
