Abstract
The invention pertains to the technical field of coking dry quenching, and relates to the pouring technology of the inlet area of a dry quenching boiler, wherein, the upper part of the area is an arch dome roof structure and the lower part is a square structure. Adopting the same bricks of the dome roof of a one-time deduster to build the dome roof near the one-time deduster, the brick type is 140 ton special bricks for dry quenching, and the brick No. is GAM2807. An expansion joint area is built by using GN53-Y108a, GN53-S110a bricks, and a side near the boiler is built by using GAM2807 bricks, 8 rows of the bricks are required totally with the side walls on the two sides built by using standard clay bricks, the part connected regularly with the boiler area is built with bricks, while the irregular area is treated by using thermal insulation pouring material. The invention resolves the problem of difficult pouring material shedding, ensures the thermal insulation of the area and the normal running of ash removing operation, and is favorable for the stabilized operation of the whole dry quenching boiler.
Description
Technical field
The invention belongs to coking Dry Quenching Technology field, is dry quenching boiler entrance area pouring process specifically.
Background technology
Dry Quenching Technology is a technology of carrying out comprehensive utilization of energy from external concentrated red Jiao of processing who introduces when the 1980s, Baosteel's First-stage Construction was built, through the main Design Research Unit of domestic coking industry---the digestion and the absorption of Zhongye Coke Resistance Engineering Technology Co., Ltd, carried out autonomous innovation.
Red Jiao of high temperature enters dried putting out in the stove, carries out thermal exchange with the low temperature rare gas element, satisfies processing requirement through the coke after the heat exchange and discharges the dried stove that puts out by the coke discharging device.And the rare gas element that has absorbed the coke sensible heat separates and enters disposable dust remover from the dried stove chute that puts out, through entering the boiler for producing steam generating behind the gravitational dust collection.Enter secondary filter again through rare gas element after the heat exchange and go further dedusting, satisfy entering the dried stove that puts out once more after the processing requirement and recycle.
Dry quenching boiler entrance area, disposable dust remover and boiler connecting portion are flexible coupling by adopting expansion joint, and the disconnected thermal recovery mould material in associated joint is carried out heat insulation.But because this domain structure complexity, difficulty of construction is big, and the disposable dust remover side that is connected with expansion joint and the mould material of boiler side very easily drop, and influence the air communication mistake.Particularly after heat insulating casting material dropped, this regional steel construction was very fast rubescent, causes the steel construction strength degradation, influences the normal operation of dry coke quenching, and then influenced the dry coke quenching generating, stopped work when serious.In the prior art, disposable dust remover top adopts clay brick to build by laying bricks or stones, and it is prefabricated in advance that expansion joint adopts two kinds of mould material to carry out, and adopts the light thermal-insulation mould material in the inner part, and the anti-mould material of washing away of heavy is adopted in the outside, is aided with the stainless steel raising intensity of pressganging able-bodied men.Expansion joint and disposable dust remover and boiler connecting portion are beaten the anti-mould material of washing away by prefabricated placenta.The actual use very fast appearance in this zone is unusual, and mould material comes off, and expansion joint is rubescent, meets the water shrinkage cracking, brings very big influence to production.Because factor affecting such as expanding, shrink, wash away causes this zone mould material very easily to come off, and influences the dried stove ordinary production of putting out, and directly causes the dry coke quenching under-capacity operation, reduce the burnt generated energy of ton.
Summary of the invention
The objective of the invention is to propose a kind of mould material that solves and drop, be beneficial to whole dried steady running of putting out stove, can reduce the dry coke quenching repair time, improve the dry quenching boiler entrance area pouring process of dry coke quenching generated energy.
Purpose of the present invention can be achieved through the following technical solutions:
Dry quenching boiler entrance area pouring process, dry quenching boiler entrance area top are the arc vault construction, and the bottom is a square structure, comprise three parts: disposable dust remover zone, expansion joint zone and boiler zone comprise following operation:
(1) in the disposable dust remover zone, adopt the brick the same to build by laying bricks or stones by the disposable dust remover vault with the used brick of disposable dust remover vault, disposable dust remover zone and expansion joint zone connecting portion number for 140 tons of dry coke quenching special bricks of GAM2807 carry out building by laying bricks or stones by row, are built three rows with brick by laying bricks or stones altogether;
(2) in the expansion joint zone, carry out building by laying bricks or stones, build four rows altogether by laying bricks or stones by row with brick number 75 tons of dry coke quenching special bricks for GN53-Y108a or GN53-S110a;
(3) in the boiler zone, by boiler side with brick number for 140 tons of dry coke quenching special bricks of GAM2807 carry out building by laying bricks or stones by row, build 8 altogether by laying bricks or stones and arrange;
(4) in the boiler zone, the both sides side wall is built 30 layers by laying bricks or stones with the standard clay brick;
(5) in the boiler zone, the regular domain that is connected with boiler is built by laying bricks or stones for 75 tons of dry coke quenching special bricks of GN53-Y108a or GN53-S110a with brick number, and irregular area is poured into a mould with heat insulating casting material.
More than in each operation, brickwork joint is 1～3mm.
Advantage of the present invention is: 1. the invention solves the difficult problem that the dry quenching boiler entrance area mould material comes off; 2. the present invention has guaranteed the heat insulation effect of dry quenching boiler entrance area; 3. guarantee normally carrying out of ash discharge operation, helped whole dried steady running of putting out stove; 4. by strengthening the structural adjustment of dry quenching boiler entrance area, prolonged the work-ing life of anti-material, compared over and must take sfgd. in three months, the anti-material in this zone can extend to 6 months work-ing life; 5. guaranteed dried normal operation of putting out stove, improved the dried generated energy that puts out stove, by reducing by 10 days maintenance in 1 year, correspondingly calculated with regard to the generated energy that increases by 10 days, annual direct benefit is: ten thousand yuan of 10*12000*24*0.52=149.76; 6. driedly put out the normal operation of stove and can effectively improve coke quality, reduce blast furnace coke ratio, the reduction ratio reaches 2%, press 340 days duration of service of dry coke quenching year, 2400 yuan in ton coke, 400 kilograms of blast furnace coke ratios, 1,500,000 tons of measuring and calculating of annual output iron, ten thousand yuan of year direct economic benefit: 10/340*400*0.02*150*10000/1000*2400=84.7.
