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 [0001] The invention belongs to the technical field of automatic control, in particular to a device for automatic monitoring and extinguishing of clean heat recovery coke oven red coke entering a belt. Background technique [0002] At present, blast furnace smelting has continuously increased the requirements for various indicators of foundry coke, especially coke moisture. The traditional concept thinks that moisture is an economic indicator, but through research, it has a great impact on the operation of the cupola furnace and the quality of casting products. The endothermic decomposition in the cupola produces H and O atoms, which enter the casting to form pores, and the pores affect the strength of the casting, and even cause cracks, leading to the scrapping of the casting. Therefore, it is quite necessary to control the moisture index in the process of producing high-quality foundry coke, and the only way to control the coke moisture in the traditional ...
