Abstract
The utility model discloses an interlocked automatic control system for smoke treatment and internal pressure of a submerged arc furnace. The interlocked automatic control system is composed of a pressure setting and detection check device, a signal processing and transmission device and a servo or variable-frequency governor; the pressure setting and detection check device is connected to the signal processing and transmission device; and the signal processing and transmission device is connected to the servo or variable-frequency governor. The interlocked automatic control system for smoke treatment and internal pressure of the submerged arc furnace can dynamically regulate the fan speed and motor power of a mating dust removal system according to the changes of internal pressure of the submerged arc furnace, thus reducing power consumption. The interlocked automatic control system can be applied to the furnace gas purification systems of various submerged arc furnaces, and can ensure standard discharge of the submerged arc furnaces during normal and abnormal operation, as well as save operating cost for enterprises.
Description
Technical field
The utility model relates to the automation control of the hot stove smoke treatment system in ore deposit, the interlocking automatic control system of pressing in hot stove smoke and dust treatment in specifically a kind of ore deposit and the stove.
Background technology
The mineral heating furnace flue quantitative changeization is big, is carrying out gas cleaning when design, if the exhaust gas volumn during by operate as normal considers that under situation such as smash stove, come out of the stove, flue dust can't all capture so, uncontrollable discharge concentration is high; If the design of the exhaust gas volumn when smashing stove cleaning system, though can reach environmental requirement preferably, energy consumption is too high, and a lot of enterprises all can't bear.
Summary of the invention
The purpose of the utility model is in the hot stove smoke and dust treatment process of ore deposit; Air quantity changes greatly; The bad problem of choosing of design air flow provides a kind of and can satisfy the interlocking automatic control system that environment protection standard requires to practice thrift system's operation energy consumption again, makes hot stove smoke and dust treatment in customer satisfaction system ore deposit and the interior pressure of stove.
The utility model is on the basis of common mineral heating furnace flue cleaning system and interlocking automatic control technology; Both are organically combined; Through pressing automatic checkout system in the stove; Make power of motor and fan delivery according to the actual condition dynamic change, effectively realize the effect of energy-saving and emission-reduction, for enterprise practices thrift operating cost.
Concrete technical scheme is: the interlocking automatic control system of pressing in hot stove smoke and dust treatment in ore deposit and the stove is by pressure given and detect calibration device, signal processing and transmitting device, servo or variable-frequency governor are constituted; Pressure given and detection connect signal to calibration device to be handled and transmitting device, and signal is handled and transmitting device connects servo or variable-frequency governor.
The furnace pressure excursion of furnace pressure during according to the hot stove operate as normal in ore deposit when smashing stove given checkout gear setting pressure influence value reaction interval, and this reaction interval is divided into five control gears, given powers of motor respectively.When system moves; The furnace pressure that checkout gear is received provides the corresponding motor operate power of confirming after detection is checked calibration device, after signal is handled, be transferred to servo or variable-frequency governor; Power of motor and rotation speed of fan are adjusted; Guarantee that blower fan and motor operate in the optimum state that satisfies under the hot furnaceman's condition in ore deposit, practice thrift operating cost, reduce the equipment idling loss.
The interlocking automatic control system of pressing in hot stove smoke treatment system in the ore deposit of the utility model and the stove has two effects; Characteristics: 1, control automatically by the interlocking of pressing in the stove; The problem of choosing of exhaust gas volumn when having solved the design of mineral heating furnace flue cleaning system; Can be by system's maximum quantity of wind design; The furnace pressure that detects according to interlock control system during operation changes; Adjustment motor operate power is saved the operating cost of dust pelletizing system; 2, because the interlocking automatic control system can be judged the running status of the hot stove in ore deposit according to the variation of furnace pressure, thereby correspondence is adjusted rotation speed of fan, has reduced the idle running rate of equipment, can prolong the service life of consumable accessorys such as draught fan impeller and filter bag.The characteristics of the interlocking automatic control system of pressing in hot stove smoke treatment system in ore deposit and the stove are dynamically to adjust the rotation speed of fan and the power of motor of supporting dust pelletizing system according to the variation of the hot stove furnace pressure in ore deposit,
Reduce power consumption, for enterprise practices thrift operating cost.
Description of drawings
Fig. 1 is the interlocking automatic control system structured flowchart of pressing in hot stove smoke and dust treatment in the ore deposit of the utility model and the stove.
The specific embodiment
As shown in Figure 1, the interlocking automatic control system of pressing in hot stove smoke treatment system in the ore deposit of the utility model and the stove is by pressure given and detect calibration device, signal processing and transmitting device, servo or variable-frequency governor are constituted; Pressure given and detection connect signal to calibration device to be handled and transmitting device, and signal is handled and transmitting device connects servo or variable-frequency governor.Described pressure given and detect calibration device, signal processing and transmitting device, servo or variable-frequency governor are prior art.
The hot stove in ore deposit designs according to the maximum exhaust gas volumn of the working of a furnace in the flue gas cleaning system design process, can both satisfy the requirement of Environmental Protection Agency's qualified discharge in the more than ten years afterwards to guarantee supporting cleaning system.Simultaneously; The interlocking automaton is set in cleaning system; Promptly dress pressure given and detection are to calibration system in the hot stove bonnet in ore deposit, and pressure inductor is wherein responded to the variation of stove pressure at any time, are after device is confirmed through detecting the school; Transmit the transformation of signal by signal processor, by transmitting device signal being passed to signal executing agency then is servo or variable-frequency governor.Variable-frequency governor will be according to the fill order that receives, and the adjustment power of motor is satisfying under the suitable rotating speed of stove operating condition motor and fan operation, the final purpose that realizes practicing thrift the cleaning system operation energy consumption.
