Description
Technical field
The utility model belongs to the silit technical field of smelting, relates to a kind of sic smelting furnace furnace gas and is drawn out of stove and realizes the smelting furnace headwall that seals between headwall and side wall when outer.
Background technology
Sic smelting furnace is made up of headwall, side wall, siege.Existing silit production technology can't be extracted the gas safety in the smelting furnace out, with the purpose that realizes holding concurrently collection and confinement of gases negative pressure smelts.Make a large amount of CO gases after the smelting furnace surface combustion, form CO on the one hand
2Directly enter atmosphere, not only wasted resource but also increased the quantity discharged of carbon, can't realize the production requirement of energy-saving and emission-reduction, low-carbon environment-friendly, can't realize that on the other hand negative pressure smelts and reduce the product power consumption.
Summary of the invention
The key of safe withdrawing gas is the realization that seals between overall situation outside subenvironment and the stove in the stove in stove, so that accomplish the isolation of furnace inner space and stove outer air, air can not get in the stove when making furnace inner space not be higher than normal atmosphere because of the air pressure of bleeding.After in the air admission stove, can form mixed gas, and mixed gas chance fire is explosive.
Because the maximization of smelting furnace; The smelting furnace both sides are assembled by several piece even tens side walls often; Therefore the sealing between the outer overall situation of subenvironment and stove in the stove generally includes between side wall and the side wall, several aspects such as between side wall and ground, between headwall and the side wall.
Duan Xiaoyan has submitted the utility application of " a kind of furnace side wall of collecting sic smelting furnace gas " on July 1st, 2011, has related to structure and side wall sealing in slit therebetween after assembling on the smelting furnace of side wall; Submit the patented claim of " sealing between a kind of sic smelting furnace side wall and ground " on July 10th, 2011, related to the sealing in slit between side wall and ground.The aforementioned sealing that does not all relate between headwall and side wall.
The purpose of the utility model is the present situation that can not well seal slit between headwall and side wall to existing silit smelting technology, and a kind of headwall cheap between headwall and side wall, convenient and reliable sealing of realizing is provided, and extracts furnace gas out to realize safety.
The technical scheme of the utility model is such: a kind of sic smelting furnace headwall, form by element body and the annex that is mounted thereon.It is characterized in that on the masonry being provided with comprise annular seal space and sealing plate annex, filling sealing compound in the annular seal space, sealing compound becomes one to seal integral body masonry with the sealing plate seal.
Said element body is exactly existing headwall, is made up of electrode, masonry.Electrode is an electrical conductor, and masonry is built by laying bricks or stones by material of construction and formed.
Said annex is the assembly that is installed on the element body, comprises annular seal space and sealing plate, for the ease of cooperating assembling with side wall, also establishes the material closure plate in case of necessity.
Said annular seal space is exactly the packing space of sealing compound, is used to load sealing compound, and sealing compound becomes a sealing whole with the sealing plate seal masonry, has realized the sealing between sealing plate and element body.
Said sealing compound is the cohesive material with good plasticity, and the scene can be selected for use the good clay water of plasticity to be in harmonious proportion and form, and requirement does not disperse, is not flowable state under the immersional wetting of water.Can add admixture in case of necessity for increasing visco-plasticity.For guaranteeing the visco-plasticity of the sealing compound that the clay mediation forms, make it not dry and cracked, be employed in the other infiltration water tank of establishing of annular seal space with the sealing compound in the water infiltration chamber.The sealing compound scene is selected for use the good clay water of plasticity to be in harmonious proportion usually and is formed, but is not limited only to be in harmonious proportion with clay, and on-the-spot visual particular case is selected for use, when sealing compound is non-clay matter, its plasticity is not done lay special stress on, and also not doing must be with the requirement of water infiltration.
Said sealing plate is processed by steel plate usually, but is not limited only to make with steel plate.The near filler side of sealing plate requires smooth, so that the attaching of packing cloth, but sealing plate is not limited only to be the plane.
The effect of said material closure plate is and sealing plate, the common charge space that forms of stifled, the interim baffle plate of material is used for the splendid attire filler.Spacing and length dimension separately between sealing plate and material closure plate require rationally, so that execute-in-place.It is characterized in that sealing plate is supporting has a material closure plate.
The effect of said filler is a crush seal cloth, and packing cloth is close on the sealing plate, realizes the sealing in slit between headwall and side wall.The scene selects for use plastic cloth as packing cloth usually, but is not limited only to plastic cloth.
Said infiltration water tank is used for the splendid attire soakage water, opens permeability hole on it and annular seal space communicates.The infiltration water tank is with pipeline and the outer water of stove, to realize giving the moisturizing of infiltration water tank.For preventing that difference of altitude from making the static pressure of water in the infiltration water tank differ too big too greatly, the infiltration water tank is along the common sectional making of short transverse.The scene usually on the tubing wall perforate make but the infiltration water tank is not limited only to tubing as the infiltration water tank.It is characterized in that the other infiltration water tank that is provided with of annular seal space, have permeability hole on the infiltration water tank, permeability hole communication seals chamber and infiltration water tank., sealing compound do not establish the infiltration water tank when need not soaking into.
The effect of said interim baffle plate is to stop up furnace charge, make furnace charge do not get into interim baffle plate, sealing plate, the space of material closure plate, the stifled splendid attire filler of forming of material.
The stifled effect of said material is to stop up filler not fall outside the runout.
Said side wall is exactly preceding " a kind of furnace side wall of collecting sic smelting furnace gas " that oneself addresses.
Cover cover body to realize the realization of upper of furnace body sealing for the ease of upper of furnace body, make supporting plate on the annex usually, with support top cover body.It is characterized in that sealing plate is supporting has a supporting plate.
The utlity model has following unusual effect:
1, the utility model is rational in infrastructure, makes simply, draws materials easily, and is with low cost.
2, the utility model execute-in-place is easy to be reliable, and seal operation realizes easily and seals with low cost.
