The control device has the advantages that wind volume and the wind pressure of the high temperature fan can be automatically adjusted to realize real-time wind volume control, and the control precision is high; the operation efficiency of the high temperature fan is improved; and the energy consumption of the high temperature fan is remarkably reduced.
Description
[technical field]
The utility model relates to a kind of blower fan energy-saving control system, particularly a kind of system equipment that is mainly used in the cement plant high-temperature blower in the New Type Dry-process Cement Production system.
[background technique]
Cement production enterprise is the major power consumer during national economy is produced, and cement industry has been listed in one of major fields that country economizes on resources.The waste heat waste gas that the rotary kiln internal combustion of new type nonaqueous cement production line produces, under the effect of kiln tail high-temperature blower, by preheater the raw material that enter before the kiln tail are carried out the preheating homogenizing, the waste heat waste gas after the cooling is extracted out by high-temperature blower and is entered waste gas treatment (dedusting and discharge).After the good raw material preheating of homogenizing in rotary kiln mature calcined material, need suitable air pressure and temperature in the rotary kiln, just can make coal dust have certain suspension time fully to burn, raw material could reach good heat treatment in kiln.The accumulation of kiln internal cause material alters a great deal, so instantaneous pressure change is frequent.Kiln tail high-temperature blower is used for adjusting the kiln internal air pressure on the one hand, the waste gas that come out of the high temperature chamotte after the calcination in the rotary kiln on the other hand, and waste gas band ash is drawn by dust precipitator by kiln tail high-temperature blower dust is handled, and waste gas is drained again.Because the pressure and the temperature of its technologic requirement control kiln tail preheater need be regulated by the high-temperature blower air quantity is controlled, the motor of therefore general high-temperature blower generally adopts speed regulating control.Generally adopt hydraulic couplers to carry out speed governing a few years ago, reach air quantity, the interior negative pressure of control kiln of adjusting high-temperature blower.But because the slip power loss that produces in adjustment process of hydraulic couplers, volume loss, mechanical loss are up to more than 10%, auxiliary operations such as caloric requirement oil pump that is produced and cooling water, rate of fault is higher, particularly bigger because of Coupler produces heat in summer, need to add four groups of oil coolers, lower the temperature by force with circulating water, water consumption is big.This has just caused more serious energy waste.
[model utility content]
The technical problems to be solved in the utility model, be to provide a kind of cement plant high-temperature blower energy-saving control device, can regulate the air quantity and the blast of high-temperature blower automatically, realized real-time air quantity control, the control accuracy height, help improving the operational efficiency of high-temperature blower, significantly reduce the energy consumption of high-temperature blower.
The utility model is achieved in that a kind of cement plant high-temperature blower energy-saving control device, comprise a motor, a high-temperature blower, a DCS (Distributed Control System, distributed control system) signal adapter, a programmable controller (PLC), an electric drive controller, a universal joint shaft joint; Described distributed control system signal adapter, described programmable controller, described electric drive controller, described motor, described universal joint shaft joint and described high-temperature blower connect in turn.
Described distributed control system signal adapter further comprises an isolating switch and a variable-frequency governor that connects by cable.
Described distributed control system signal adapter is connected by connection with programmable controller; Described programmable controller is connected by connection with described electric drive controller; Be connected by cable between described electric drive controller and the motor.
Advantage of the present utility model is: realized the continuous control of air quantity, the control accuracy height, help improving the operational efficiency of blower fan, reduced the energy consumption of high-temperature blower, reduce motor noise, realize soft start and soft stopping, reducing the impact of electrical network inrush current, the reliability height has reduced maintenance cost.
