Abstract
The utility model discloses a heat insulation device of a dust remover, which performs heat insulation work of carrier gas entering into the dust remover after coal moisture control and is energy-saving. The heat insulation device of the dust remover comprises a carrier gas input pipe connected with an air inlet end of the dust remover, and a coke oven flue gas pipe is connected with the carrier gas input pipe through a valve; the carrier gas input pipe is provided with a flow meter; and each of the air inlet end and the exhaust end of the dust remover is provided with a thermometer. The heat insulation device of the dust remover is suitable for heat insulation of dust removers in coking industry.
Description
Technical field
The utility model relates to coal damping carrier gas dedusting field, relates in particular to a kind of fly-ash separator attemperator.
Background technology
Because tamping coke furnace is to coal charge moisture stabilization requirement height, the coal damping operation that just is absolutely necessary one, one of common method is exactly the damping of rotary shelf drier coal, the water vapour that drying process produces is taken out of by having the higher carrier gas of temperature, a part of coal dust is also taken in carrier gas simultaneously out of, therefore needs with fly-ash separator carrier gas to be filtered.Because contain water vapour and coal dust in the carrier gas simultaneously, if carrier gas temperature in fly-ash separator descends to some extent, reach gas dew point, then steam will combine with coal dust, stops up fly-ash separator, and the drag losses when increasing gas by fly-ash separator reduces efficiency of dust collection.
At present for the measure that gas in the fly-ash separator is taked is, pressurized air is by the recirculation blower suction, gas in the fly-ash separator is incubated to behind its pre-heating temperature elevation to 120 ℃ with middle pressure steam, and the both power consumptions of this mode, consumption nitrogen consume steam again.
The utility model content
The technical problem that the utility model solved provides a kind of fly-ash separator attemperator, and the energy is saved in the work that the carrier gas that enters fly-ash separator after the coal damping is incubated.
The technical solution adopted in the utility model is, the fly-ash separator attemperator comprises the carrier gas input tube of the inlet end that is connected in fly-ash separator, and the coke oven flue waste pipe is connected in the carrier gas input tube by valve.
On the described carrier gas input tube under meter is installed.
The inlet end of described fly-ash separator and exhaust side respectively are provided with thermometer.
The beneficial effects of the utility model are that the temperature that guarantees gas in the fly-ash separator is effectively utilized the heat of industrial gaseous waste on dew point, reduce energy consumption and exhaust gas emission, reduces oxygen level in the fly-ash separator, guarantees safe production.
Description of drawings
Fig. 1 is the utility model structural representation.
Be labeled as among the figure: 1-carrier gas input tube, 3-coke oven flue waste pipe, 4-drying machine, 5-fly-ash separator, 6-vapor pipe, 7-under meter.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fly-ash separator attemperator of the present utility model as shown in Figure 1 comprises the carrier gas input tube 1 of the inlet end that is connected in fly-ash separator 5, and coke oven flue waste pipe 3 is connected in carrier gas input tube 1 by valve.Utilize the part facility of former attemperator, carrier gas input tube 1, carrier gas input tube 1 is connected in coke oven flue waste pipe 3, introduce pyritous coke oven flue waste gas by valve regulated, mix with the carrier gas in the carrier gas input tube 1, be transported in the fly-ash separator, the gas after filtering through fly-ash separator is discharged through gas exhaust duct.Pyritous coke oven flue waste gas is the temperature height not only, can improve the carrier gas temperature, avoid that the carrier gas temperature drops to that dew point causes steam and dust you connect the furnace charge that stops up fly-ash separator, because coke oven flue waste gas oxygen level is less, can effectively control the oxygen level of mixed carrier gas in safety range simultaneously.
On the described carrier gas input tube 1 under meter 7 is installed.Under meter 7 is sneaked into the flow of the coke oven flue waste gas of carrier gas in order to detection, flow is adjusted to the size of needs according to the field condition regulated valve.
The inlet end of described fly-ash separator 5 and exhaust side respectively are provided with thermometer.Thermometer provides the temperature parameter in the fly-ash separator 5, carries out the stack gases Flow-rate adjustment along with gas temperature in the fly-ash separator 5 changes in the operation, and temperature will remain on the dew-point temperature, also will consider the highest withstand temp of filtrate simultaneously.
Claims (3)
