Abstract
The invention discloses a sealing process of a horseshoe glass melting kiln waste gas flue for burning producer gas, which is a process for sealing the top-surface outer wall and the side-face outer walls of the waste gas flue with a plurality of layers of rubberized fabrics, wherein the plurality of layers of rubberized fabrics are glass fibre cloths coated and soaked with a polyvinyl acetate emulsion; and the number of the rubberized fabrics is 3-5 layers. The outer surface of the waste gas glue is completely sealed through the sealing process using the plurality of layers of rubberized fabrics, and the waste gas glue is prevented from blasting; and therefore, influence on production and personal injury are avoided.
Description
Technical field
The present invention relates to the sealing technology of the waste gas flue of furnace burning producer gas horse shoe shaped glass melter.
Background technique
Glass melter is the most important Thermal Equipment of glass works.The waste gas flue is the necessary channel that the part producer gas that retains in waste gas and when commutation gas regenerator is discharged.The waste gas flue is the important auxiliary facility of glass melter, therefore guarantees that the safe and stable operation of glass melter waste gas flue in commutation process is the top priority of glass works.For many years, because the sealing technique imperfection of furnace burning producer gas horse shoe shaped glass melter waste gas flue, the waste gas flue " is blown out " phenomenon and is happened occasionally, the main cause that the phenomenon of " blowing out " produces is: after the glass melter commutation, waste gas (containing the part producer gas during commutation) is discharged glass melter by the waste gas flue, be negative pressure this moment in the waste gas flue, if the waste gas flue is well sealing not, ambient air is easy to be inhaled into the waste gas flue, producer gas contained in the ambient air that sucks and the waste gas mixes, reach the explosion limit of coal gas, thereby produced " blowing out " phenomenon.Influenced the safe and stable operation of glass melter.
Summary of the invention
The sealing technology that the purpose of this invention is to provide a kind of furnace burning producer gas horse shoe shaped glass melter waste gas flue adopts this technology can eliminate " blowing out " phenomenon of waste gas flue.
For achieving the above object, the present invention takes following design proposal:
The sealing technology of this furnace burning producer gas horse shoe shaped glass melter waste gas flue, it is the technology that seals with multilayer brush coating cloth at waste gas flue end face outer wall and side outer wall.
Described multilayer brush coating cloth is to be coated with the glass fiber cloth that soaks polyvinyl acetate emulsion, and its number of plies is 3～5 layers.
When waste gas flue end face and side outer wall carry out the sealing of multilayer brush coating cloth, smear one deck clay mortar in the flue outer wall surface earlier; After waiting to parch, the glass fiber cloth that will be soaked with polyvinyl acetate emulsion is again extracted and is sticked; Flatten with the brush that dips in the latex polyvinyl acetate emulsion then, bubble or wrinkle are arranged to prevent to produce in the brush coating process; Repeat to paste brush one deck down after waiting to parch again; Paste three to four layers altogether.
Waste gas flue end face and side outer wall seal with multilayer brush coating cloth, adjacent two sections sealing layer is to disconnect, the telescopic chute that leaves 10mm～15mm in its substantially horizontal together, the thermal expansion of glass fiber cloth when being beneficial to the kiln heating-up furnace, because build the requirement that seam can satisfy expansion by laying bricks or stones between the brick material down in the temperature (300 ℃～400 ℃) of waste gas flue, and multilayer brush coating layer of cloth 5 expansion ratio brick material under this temperature is big, so reserve dilatation joint.Under the normal temperature state, sealing layer disconnects.When the waste gas flue came into operation, along with the rising of temperature, the expansion meeting of layer 5 was filled up the dilatation joint that disconnects substantial.Be coated with one deck aluminium paint after all parching again.
Advantage of the present invention is: adopt this sealing technology, can effectively completely cut off ambient air and suck the waste gas flue, avoid the waste gas flue " to blow out " generation of phenomenon.

Embodiment
Embodiment 1
In certain vial engineering, the wide 930mm of waste gas flue of its furnace burning producer gas horse shoe shaped glass melter, the about 32m of one-sided length, waste gas flue in service is negative 160 Pascals, because this sealing technology of pilot production when the waste gas flue is designed and constructed, go into operation so far that waste gas flue and glass melter operate steadily, " blowing out " phenomenon never occurs.
This sealing technology promptly adopts this sealing technology through on probation in furnace burning producer gas horse shoe shaped glass melter waste gas flue, glass melter and waste gas flue operate steadily, and has stopped the waste gas flue and " has blown out " generation of phenomenon.
Claims (6)
