Description
Technical field
The utility model belongs to the industrial furnace equipment technical field in sulfur recovery facility, is specifically related to a kind of acidity
Gas burning furnace composite lining structure.
Background technology
Sour gas burning furnace is the key equipment in sulfur recovery facility, and its design condition is harsh, and operating temperature is up to
1250 DEG C～1400 DEG C, H2S corrosive mediums are strong.Therefore sour gas burning furnace refractory heat-insulating lining structure design and selection are to pass
It is important, section air inlet position is especially bored, circumferentially substantial amounts of perforate is furnace lining damageable zone.Existing sulfur recovery facility
The furnace lining of middle sour gas burning furnace mainly adopts brick mix structure, or simple firebrick structure, the structure although to meet stove
The resistance to burning of lining and the requirement of thermal insulation, but it is relatively costly, and difficulty of construction is larger, and occurs burning down in engineer applied.Pin
Must design cone section structure various special shaped brick kinds, and special shaped brick not only manufactures complexity, and design and improper can form more
Waste product, increased material cost.Installation accuracy is strictly controlled during masonry construction, will to the technical merit of operating personnel
Ask high, increased cost of labor.
Publication No. CN204923062U, the day for announcing are on December 30th, 2015, a kind of entitled " sour gas burning furnace cone
A kind of sour gas burning furnace cone section furnace lining structure is disclosed in the Chinese patent of section furnace lining structure ", the construction interior is Titanium
Plate, is fastened by the long pole and nut that are fixed on casing metal wall, and anchor is arranged between castable refractory and heat insulating casting material
Gu brick.The pole selection for being used to fix metallic titanium plate in the patent is difficult, if using metal, due to metal heat-conducting rate it is big,
Furnace high-temperature is caused to pass to casing metal wall along pole, the serious consequence for causing housing to burn, if using ceramic material, very
Difficulty meets the tensile strength of securing member, and leading effectively to fasten.In addition, titanium starts and H at 600 DEG C2S reactions generate sulfuration
Thing, the Ti and H at 1200 DEG C2S reactions generate Ti2S3, and temperature is up to 1400 DEG C, when titanium plate surface is long in sour gas burning furnace
Between and H2S contact reacts, and there is heavy corrosion risk and destroys titanium plate fixation, therefore has much room for improvement.
The content of the invention
The purpose of this utility model is to provide a kind of sour gas burning furnace composite lining structure, to solve prior art
The technical problem that anchoring piece thermal conductivity causes greatly furnace shell temperature too high and destroys in furnace lining structure.
The utility model is adopted the following technical scheme that：A kind of sour gas burning furnace composite lining structure, including anchoring piece and
Castable, the anchoring piece includes combination anchor brick, and the combination anchor brick includes pedestal and the anchoring being fixed together
Body, the pedestal is mounted in the pre- metal bitch being welded in furnace wall, and ceramic fibre is packed between the pedestal and metal bitch
Dimension, the pedestal is made using heat-barrier material.
The anchoring piece also includes metal anchor studs.
Metal anchor studs and combination anchor brick arranged for interval, adjacent metal anchor studs and the spacing of combination anchor brick are
250～350mm.
The castable includes outer layer heat insulating casting material and internal layer castable refractory, and the metal anchor studs are outer for anchoring
Layer heat insulating casting material, the combination anchor brick is used to anchor outer layer heat insulating casting material and internal layer castable refractory.
The base interior is added with toughened fiber.
The pedestal and anchoring body are threaded togather.
The material of the anchoring body is corundum-mullite.
The beneficial effects of the utility model are：The utility model anchors monolithc lining using combination anchor brick, both simple Jing
Ji, and highly effective.Combination anchor brick is made up of the pedestal with heat-blocking action and anchoring body two parts, is giving full play to anchoring
While brick is acted on, heat transfer is effectively blocked, and ceramic fibre has been clogged between metal bitch and pedestal, further
Reduce heat transfer coefficient, it is ensured that furnace wall is operated in safe temperature range, improves stove whole service life.
Further, castable lining is anchored by metal anchor studs and combination anchor brick jointly, makes anchoring more effective.Gold
Category anchor studs anchoring outer layer heat insulating casting material, contact, it is to avoid metal heat preservation follows closely high-temperature oxydation with counter-fire face castable.
Further, base interior addition toughened fiber, it is to avoid anchored brick and furnace shell directly contact, blocks furnace high-temperature
To furnace shell transmission.
