Abstract

The invention discloses an oven-drying working process for a coke dry quenching system. The process comprises the following steps: step 1, drying a dry quenching oven with warm wind; step 2, drying the dry quenching oven with coal gas after the step 1 is finished; and step 3, after the step 2 is finished, putting red-hot coke in the dry quenching oven so that a refractory material is heated to 950-1050 DEG C at the speed of less than or equal to 30 DEG C/h, thereby completing the oven-drying operation. According to the oven-drying working process for the coke dry quenching system, in the warm wind drying process, the temperature of a boiler collecting box is in conformity with the temperature of a steam pocket, thus the gap generated due to the tremble of the boiler when an airlift pump works is avoided so that boiler steam can not be intermixed with dry air, thereby correctly and timely judging the drying condition of the dry quenching oven; and in the coal gas drying stage, the refractory material is heated according to a heating crystal form conversion curve through reasonably controlling the coal gas-air proportion and heating speed, thereby avoiding the conditions that mixed coal gas extinguishes, the refractory material is broken or damaged, and the like. Thus, by the process disclosed by the invention, the service life of the dry quenching oven refractory material can be prolonged, the safe work of a boiler system can be ensured and the service life of the boiler system is prolonged, and oven-drying working time can be shortened at the same time.

Description

Oven-drying working process for coke dry quenching system
Technical field
The present invention relates to a kind of coking technology field, particularly a kind of roast technic of dry quenching system.
Background technology
Need body of heater is dried before coke dry quenching furnace is gone into operation, separating out the moisture of refractory materials in the stove, and body of heater is heated up, thereby be connected with the normal production red furnace temperature when burnt of packing into, prevent refractory materials cracking of building body or damage.
In the prior art, oven-drying working process for coke dry quenching system is divided into altogether three phases, and the fs is the warm air drying stage, and its main purpose is that the dried refractory materials moisture content that puts out in the stove is separated out; Subordinate phase is the coal gas baker stage, need prevent refractory materials cracking of building body or damage; Phase III, this stage mainly was when continuing to guarantee that the coke oven masonry heats up by curve, lays the first stone for guaranteeing the adjustment of producing each parameter as a trial in order to throw the red burnt stage.
Mainly there is following defective in existing technique:
1, in the warm air drying stage, because boiler header water temperature and drum temperature differ larger, cause boiler systems to tremble, easily make the damage boiler cause steam to sneak into the oven dry air, thus the dried oven dry situation of putting out stove of judgement that can't be promptly and accurately.
2, in the coal gas baking stage, because the control of the proportioning of coke-oven gas and air is relatively poor, at the coal gas baking stage flame-out, the dried oven refractory that puts out occuring easily can not heat up according to intensification transformation of crystal curve, easily causes refractory materials to break or damages.
Therefore need to improve oven-drying working process for coke dry quenching system of the prior art, to overcome defective of the prior art.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of oven-drying working process for coke dry quenching system, can prevent that at the warm air drying stage boiler systems from trembling, avoid damage in boilers the slit to occur and make steam sneak into the oven dry air, cause can't be promptly and accurately the dried oven dry situation of putting out stove of judgement; And in the coal gas baking stage, accurately control the proportioning of coke-oven gas and air, and avoid flame-out, the dried oven refractory that puts out of coal gas baking stage to heat up not according to intensification transformation of crystal curve, cause refractory materials to break or damage.The concrete scheme of this technique is:
Oven-drying working process for coke dry quenching system of the present invention may further comprise the steps:
