Abstract
The invention discloses a dust removal control system controlled by a set of programmable logic controller (PLC). When a furnace roof smoke guide vehicle or a coke side dust removal coke guide reach a predetermined position, a dust removal guide sleeve on the vehicle is conducted with a fixed interface valve. After receiving a signal transmitted by a coking system, a dust removal fan rotates at a high speed from a low speed; and the soot passes through each dust collecting main, the dust is removed through a ground station, and then the soot is discharged into the atmosphere through a chimney. When the fan rotates at the high speed, a special in front of a bag type dust collector is closed; and after the dust removal is finished, the fan turns to rotate at the low speed, and the special valve is opened to keep the pressure of the system and cool a heat storage chamber cooler in a coke discharging dust removal system. When the fan rotates at the low speed, the PLC controls a pulse controller of the bag type dust collector to perform back flowing so that the dust attached to a cloth bag falls, meanwhile, an ash discharging valve acts to discharge the ash to a scraper ash conveyor, and the ash is conveyed to an ash storage bin, wetted and transported by an automobile.
Description
Technical field
The present invention relates to a kind of PLC system, especially control by a cover PLC system dust removing.
Background technology
Because historical reasons, in coke oven smoke emission maximum, endangering the most serious is a large amount of tobacco and the coal dust that the process of coalingging escapes.According to interrelated data, the emission of coke oven coal-charging process flue dust and nuisance accounts for 60% of coke oven pollutant, wherein the BSO discharge capacity is that 0.499kg/t coal, BaP total emission volumn are 0.908 * 10-3kg/t coal, is respectively BSO and BaP ton coal discharge capacity 13.7 times and 50 times of the discharging of the coke.Harmful substances such as the BaP in the flue dust are that carrier exists with TSP, therefore, are to solve the fundamental way of harmful harm and the link of most critical to the collection and treatment of TSP.Failed auxiliary construction coke oven coal-charging, the effective treatment facility of the flue dust that discharges of the coke at that time in the coke oven construction, and went into operation for many years, the disposal of pollutants of coke oven can't be up to standard, to plant area and around atmospheric environment cause severe contamination.In view of the maturation of present coke oven improvement technology, the raising of environmental protection of enterprise consciousness, it is very necessary proposing the coke oven smoke treatment engineering.
Summary of the invention
Dust pelletizing system of the present invention is controlled by a cover PLC, behind furnace roof smoke-guiding car or coke side dust-collecting coke guide car arrival precalculated position, and dedusting guide pin bushing on the car and the conducting of fixed interface valve.At this moment after dedusting fan was received the signal that coking system transmits, beginning was transferred at a high speed by low speed, and the control of dust main of flue dust by separately after earth station's dedusting, enters atmosphere by chimney.In blower fan ran up, the very valve before the sack cleaner cut out, and after dedusting finished, blower fan changed low cruise over to, and very valve is opened, to keep the regenerator cooler in system pressure and the cooling coke discharging and dedusting system.When the blower fan low cruise, the pulse control instrument of PLC control sack cleaner carries out blowback, makes attached to the dust on the cloth bag and drops, and unloading valve action simultaneously is discharged into the scraper ash-transmission machine with ash and is transported to the grey storehouse of storage, automobile outward transport behind the humidification.Certainly, needing to be collected in the burnt dirt of storing in the grey storehouse before dust collection for charging sprays in the deduster of the usefulness of coalingging with pre-spray equipment.In entire work process, the high low speed of blower fan switches, very the switching, operation, the switching of pulse control instrument and the coordination of scraper ash-transmission machine and unloading valve of pre-spray equipment of valve are controlled realization by PLC.
The present invention need transform existing coke guide, should will be connected the guide pin bushing cancellation between coke guide and the dust-removing vehicle, increases the guide pin bushing that is connected between coke guide and the fixed interface valve; Change dust-removing vehicle into smoke-guiding car.
Description of drawings
Fig. 1 is a coke discharging and dedusting schematic flow sheet of the present invention;
Fig. 2 is a coal loading dedust system schematic flow sheet of the present invention;
Purpose of the present invention, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
As shown in Figure 1, coal loading dedust system of the present invention is formed by moving with fixture two parts.
Mobile device is located on the furnace roof smoke-guiding car, and this car belongs to moving leads cigarette equipment, is mainly used to the coal-charging smoke of furnace roof dedusting hole loss is docked with fixing main, and flue dust is directed into carries out dedusting in the ground station for dust removal.
Seal sleeve is used for deriving the flue gas of coalingging.Sleeve and dedusting hole seat adopt ball face sealing, and sleeve is provided with the elastic compensating device, and the deviation of dedusting hole seat is had better adaptability.Flue is provided with adjustable air inlet, and control blending cold air amount guarantees that flue-gas temperature meets the requirements.
The fixture content comprises control of dust main that the fixed interface valve of the band air draught turnover panel that is installed on the coke side furnace roof forms, surface duct, silencer, ventilation unit, chimney etc.
The smoke-guiding car traveling is opened the dedusting port lid behind carbonization chamber location to be coaling, fall seal sleeve, and smoke discharging pipe on the smoke-guiding car and fixed interface valve are connected at this moment.Flue gas sucks from sleeve when coalingging, and after fixed interface enters the pulse bag type dust collector purification, drains into atmosphere by exhaust blower through chimney again, the unified outward transport of the dust that deduster is collected.Before coal loading dedust system is started working, by pre-spray equipment the burnt dirt of collecting in the coke discharging and dedusting process is sprayed into sack cleaner, prevent that the thick substances in the flue gas from stopping up cloth bag.
Systematic parameter:
As shown in Figure 2, the present invention ground station for dust removal system of the discharging of the coke is made up of three parts:
First is the large-scale air-suction cover that is fixed on the coke guide and moves with coke guide, and the conversion equipment of flue gas being sent into coke side control of dust main.This covering device is arranged on the coke guide, belongs to the coke guide scope of design.
Second portion is provided in a side of the control of dust main and the flue gas switching valve of burnt platform top.
Third part is to be arranged at the final equipment that stop working flue gas, purify on ground.Comprise pipeline, heat accumulating type cooler, pulse bag type dust collector, centrifugal blower, silencer, chimney etc.
The exhaust gas volumn of coke discharging and dedusting system and have related parameter as follows:
Because it is to be interrupted according to certain rules periodically to carry out that coke oven discharges of the coke, in order to reduce operating cost, design is joined variable speed fluid coupling between dedusting earth station main air blower and motor, makes the fan speed regulation operation.Promptly blower fan runs up when the discharging of the coke, At All Other Times the blower fan low-speed running.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
