Description
Technical field
The present invention relates to fire door water supply installation, refer in particular to a kind of fire door multichannel water supply installation.
Background technology
Annular furnace fire door is the visual plant in high temperature annealing unit, be for the first cooling section in stove and the second cooling section carry out isolating and arrange can the Steel structure door of knee-action, this is because the temperature of both sides is higher, and itself needs refrigerating unit, to guarantee can not be out of shape when door opening and closing.
Every 3.15 hours door opening and closings once, table rotates annular furnace fire door, rotates and about needs 3.5 minutes, and rotate after terminating, fire door is closed, and guarantees that the temperature head between the first cooling section and the second cooling section remains on 200 DEG C.In the both sides of fire door, have the flexible pipe with fire door lifting, what flexible pipe was external is waterpipe, and logical water coolant in waterpipe, the cooling as fire door is used.
Fire door with refrigerating unit is made up of unlike material, the 304 material pipelines of diameter 150mm in fire door, fixing for fire door dividing plate; Have two groups of circulating lines in the middle of fire door, caliber is 114.3mm, and material is 310S, and in it, the medium of circulation is cooling air, claims these two groups of circulating lines to be cooling air pipeline.Above-mentioned waterpipe and cooling air pipeline and boiler roof sealing part constitute fire door refrigerating unit.Fire door dividing plate is then bolted on waterpipe.Because fire door both sides temperature is more than 800 degree, outside dividing plate, be covered with the ceramic fiber blanket that thickness is 50mm.
Only have a road waterworks in above-mentioned refrigerating unit, the general recirculated water adopting enterprise itself, the discharge of design is usually 8m
3/ h, the inlet/outlet temperature difference is 10 DEG C.By the operation of for some time, discharge can decline gradually, makes the temperature of outlet constantly increase, and goes into operation two months just close to the design temperature upper limit, causes cooling performance to decline, had a strong impact on the safety of fire door.Once fire door causes distortion because cooling is not in place, cannot normally be elevated, the coil of strip in stove there will be compromised quality or scraps, and brings have a strong impact on production.
Above-mentioned refrigerating unit also has employing pure water as water coolant, as shown in Figure 2, water coolant enters inlet channel by pure water supply system, by being arranged on several feed water flow gauge FM21, the FM22 on inlet channel, first thermopair TC21 and first-hand movable valve group V21 enters fire door 20, from fire door 20 flow out backwater by being arranged on the second-hand's movable valve group V22 outlet conduit, second thermopair TC22, water flow meter FM23, and several manual valve V23, V24 etc. enter pure water return water system.Because this refrigerating unit also Jin You mono-road pure water supplies water to fire door, each under meter and thermopair are for showing the flow and water temperature that flow through fire door, if because the something unexpected happened such as recycle pump damage wherein or water tank fault, then fire door supplies water and will interrupt, and the water in fire door is by rapid temperature increases, serious meeting causes pipeline burst, fire door is out of shape, and fire door is by stuck in stove, and whole stove can not normally rotate, affect unit normally to produce, and cause product quality of lot accident.
The patent No. is CN201120285155.6 " seal furnace door cooling system of continuous furnace ", it is a kind of seal furnace door cooling system of continuous furnace, its water-cooled tube is arranged around fire door at the fire door place of body of heater, it also comprises cyclic water tank, the feed-water end of water-cooled tube is by the first water intaking valve, recycle pump communication loop water tank, the water side of water-cooled tube is by the first outlet valve communication loop water tank, this recirculated water circulates round stove gate, the heat major part at such stove gate place is all recycled water-band and walks, reduce the temperature rise of fire door, the temperature of fire door is made to be basically stable at below the temperature of trouble-free service, though it has good cooling results, circulating water line not easily blocks, equipment is simple, the feature such as easy to maintenance, but because it only has a road water supply installation, when this road system goes wrong, serious consequence will be caused.
