Abstract
The invention discloses a clean-type burning coke automatic monitoring and quenching device for a heat recovery coke furnace, which comprises a coke transport system (1), a spraying system (2), an on-line temperature measurer (3), a water supply system (4), an intelligent control system (5) and an actuating system (6), wherein a plurality of coke quenching sprayers of the spraying system (2) are positioned above a belt of the coke transport system (1); the tail end of the duct of the spraying system (2) is connected with the actuating system (2); one end of the actuating system (2) is connected with the water supply system (4) through a valve and a duct, and the other end is connected with the intelligent control system (5) through a circuit; and the on-line temperature measurer (3) is positioned above the belt of the coke transport system (1) and connected with the intelligent control system (5) through the circuit. The invention reduces the burning loss probability and prolongs the service life of the belt; the concentration of carbon monoxide is lowered, thereby preventing workers from asphyxia due to oxygen deficiency or from carbon monoxide poisoning; and the invention prevents the coke bin afterburning accident.
Description
Technical field
The invention belongs to the automatic control technology field, be specifically related to the device of automatically monitoring, extinguishing after red Jiao of a kind of clean type heat recovery coke oven enters belt.
Background technology
At present, blast-furnace smelting requires to improve constantly to the indices of foundry coke, especially coke moisture.Traditional concept thinks that moisture is an economic target, but by studying, its Cupola operation and casting product quality impact are larger, when moisture is too high, cause molten iron temperature to reduce, even the accident of working of a furnace deterioration, blowing out occurs; Moisture carries out thermal endothermic decomposition in cupola furnace, produce H, O atom, enters and produces pore in the foundry goods, and pore then affects casting strength, even causes crackle, causes foundry goods to be scrapped.The control of therefore producing moisture content index in the superior casting coke process is quite necessary, and the unique channel of conventional wet extinguishing technique control coke moisture is to shorten the quenching time, can bring thus red Jiao to go up conveying belt easily with its damage, and red Jiao makes, and airborne oxygen concentration greatly reduces in the corridor, and produce carbon monoxide and cause workman's anoxia asphyxia or carbon monoxide poisoning, coke bin resume combustion accident occurs to cause after entering coke bin in red Jiao.
Summary of the invention
The present invention will solve the upper belt scaling loss adhesive tape of red Jiao and red Jiao to enter the problem that the resume combustion of initiation coke bin occurs behind the coke bin.
Technical scheme of the present invention:
A kind of clean type heat recovery coke oven red Jiao monitor automatically, blanker, comprise coke transportation system 1, sprinkling system 2, temperature measurement on-line device 3, waterworks 4, intelligence control system 5, executive system 6, some coke quenching nozzles of described sprinkling system 2 are positioned at the belt top of described coke transportation system 1, the end of described sprinkling system 2 pipelines is connected with executive system 2, executive system 6 one ends are connected with waterworks 4 with pipeline by valve, the other end is connected with intelligence control system 5 by circuit, described temperature measurement on-line device 3 is positioned at the belt top of described coke transportation system 1, is connected with described intelligence control system 5 by circuit.
Beneficial effect of the present invention:
1. reduce the scaling loss probability, prolonged belt life;
2. improve oxygen concentration, reduced carbon monoxide concentration, prevented workman's anoxia asphyxia or carbon monoxide poisoning;
3. stoped the generation of coke bin resume combustion accident.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of clean type heat recovery coke oven red Jiao monitor automatically, blanker, comprise coke transportation system 1, sprinkling system 2, temperature measurement on-line device 3, waterworks 4, intelligence control system 5, executive system 6, some coke quenching nozzles of described sprinkling system 2 are positioned at the belt top of described coke transportation system 1, the end of described sprinkling system 2 pipelines is connected with executive system 2, executive system 6 one ends are connected with waterworks 4 with pipeline by valve, the other end is connected with intelligence control system 5 by circuit, described temperature measurement on-line device 3 is positioned at the belt top of described coke transportation system 1, is connected with described intelligence control system 5 by circuit.
Described device working process is as follows: occur red defocused on the belt of coke transportation system, 1# temperature measurement on-line device feeds back to intelligence control system with temperature signal, then drive executive system and open rapidly the waterworks valve, the 1# coke quenching nozzle of sprinkling system is sprayed water to red Jiao, and controls its water spray opening time according to belt travelling speed and spray header length by the time relay; When passing through subsequently 2# temperature measurement on-line device, to the coke of temperature over-range still, the 2# coke quenching nozzle of sprinkling system continues to red burnt water spray, the same 1# of method; Until drop to assigned temperature when following when temperature, executive system valve autoshutdown reaches the function of red Jiao on the automatic distinguishing belt.
Claims (1)
