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

Red Jiao of a kind of clean type heat recovery coke oven monitors automatically, blanker

Technical field

The invention belongs to the automatic control technology field, be specifically related to the red burnt device of monitoring automatically, extinguishing behind the belt that gets into of a kind of clean type heat recovery coke oven.

Background technology

At present, blast-furnace smelting improves constantly each item index request of foundry coke, especially coke moisture.Traditional concept thinks that moisture is an economic target, but through studying, it is bigger to cupola furnace operation and casting product quality influence, when moisture is too high, causes molten iron temperature to reduce, even the accident of working of a furnace deterioration, blowing out takes place; Moisture carries out thermal endothermic decomposition in cupola furnace, produce H, O atom, gets in the foundry goods and produces pore, and pore then influences 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 the quenching time that shortens; Can bring red Jiao to go up conveying belt thus easily with its damage; And red Jiao makes that airborne oxygen concentration greatly reduces in the corridor, and produces carbon monoxide and cause workman's anoxia asphyxia or carbon monoxide poisoning, redly burntly coke bin resume combustion accident takes place to cause after getting into coke bin.

Summary of the invention

The present invention will solve red Jiao to go up belt scaling loss adhesive tape and the red burnt problem that the resume combustion of initiation coke bin takes place behind the coke bin that gets into.

Technical scheme of the present invention:

Red Jiao of a kind of clean type heat recovery coke oven monitors 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 quenching shower nozzles of said sprinkling system 2 are positioned at the belt top of said coke transportation system 1; The end of said sprinkling system 2 pipelines is connected with executive system 2, and executive system 6 one ends are connected with waterworks 4 with pipeline through valve, and the other end is connected with intelligence control system 5 through circuit; Said temperature measurement on-line device 3 is positioned at the belt top of said coke transportation system 1, is connected with said intelligence control system 5 through 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 a structural representation of the present invention.

Embodiment

Said device working process is following: on the belt of coke transportation system, occur red defocused; 1# temperature measurement on-line device feeds back to intelligence control system with temperature signal; The driving execution system opens the waterworks valve rapidly then; The 1# quenching shower 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 2# temperature measurement on-line device subsequently, to the coke of temperature over-range still, the 2# quenching shower nozzle of sprinkling system continues to red burnt water spray, the same 1# of method; Up to dropping to assigned temperature when temperature when following, the executive system valve is closed automatically, reaches the function of extinguishing red Jiao on the belt automatically.

Claims

Red Jiao of clean type heat recovery coke oven monitor automatically, blanker; It is characterized in that; Said device comprises coke transportation system (1), sprinkling system (2), temperature measurement on-line device (3), waterworks (4), intelligence control system (5), executive system (6); Some quenching shower nozzles of said sprinkling system (2) are positioned at the belt top of said coke transportation system (1); The end of said sprinkling system (2) pipeline is connected with executive system (2), and executive system (6) one ends are connected with waterworks (4) with pipeline through valve, and the other end is connected with intelligence control system (5) through circuit; Said temperature measurement on-line device (3) is positioned at the belt top of said coke transportation system (1), is connected with said intelligence control system (5) through circuit;

The operational mode of said device is following:

A) appearance is red defocused on the belt of said coke transportation system (1); 1# temperature measurement on-line device (3) feeds back to said intelligence control system (5) with temperature signal; Drive said executive system (6) then and open said waterworks (4) valve rapidly; The 1# quenching shower nozzle of said sprinkling system (2) 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 b) passing through 2# temperature measurement on-line device (3) subsequently, to the coke of temperature over-range still, the 2# quenching shower nozzle of said sprinkling system (2) continues to red burnt water spray, and method is same a);

C) up to dropping to assigned temperature when temperature when following, said executive system (6) valve is closed automatically, reaches the function of extinguishing red Jiao on the belt automatically.
