Abstract
The utility model belongs to a device for controlling temperature of gas entering a dry pulse bag filter dust remover, in particular a blast furnace gas dry pulse bag filter dust remover cooling device which comprises a waste gas pipe. A sleeve with two closed ends is disposed outside the waste gas pipe; a spraying pipe axially and uniformly distributed with blowholes is disposed above the waste gas pipe in the sleeve; an water outlet disposed in a lower portion of the sleeve is connected with a water recovery tank through a water outlet pipe; and the water outlet of the water recovery tank is connected with the spraying pipe in the sleeve through a water delivery pipe provided with a water pump. The device can control the temperature of the gas entering the dry pulse bag filter dust remover within a rated range, thereby prolonging the service life of a filter bag and ensuring the normal operation of a bag filter dust remover.
Description
Technical field
The utility model belongs to the device, particularly blast furnace gas dry pulsed jet cloth filter heat sink that control enters dry method pulsed jet cloth filter gas temperature.
Background technology
The blast furnace gas dry pulsed jet cloth filter system that ironmaking is produced, by gravitational precipitator come half clean waste
Coal gas enters the lower box of sack cleaner through arm, at first carries out mechanical after separating, dust-laden coal gas upwards arrives cloth bag and filters, the fine dust filter purifies back coal gas and is pooled to upper box by filter bag attached to the filter bag outer surface, sends through purified gas arm, house steward.Filter bag caves in during filtration, is the plum blossom shape under the stopping of framework.After being filled into certain hour, the dust on filter bag surface increases, and causes dust remover resistance to rise, and needs deashing this moment.Purge mode adopts timing mode, and the experience of groping according to operating process is set at T minutes (30-90min) with cleaning cycle.Each cylindrical shell deashing goes round and begins again successively.Regularly the advantage of purge mode is that operating ratio is than balance.
Cloth bag chamber hypocentrum ash bucket is delivered to big grey storehouse by pneumatic ball valve, pneumatic clock-type unloading valve, pneumatic wear resistance ball valve and wear-resistant liner ash conveying pipe with grey wind.Reducer pipe top pneumatic ball valve is set to often open (before the start, closing pneumatic ball valve when ashless in the grey storehouse in order to avoid lock wind is opened when unloading ash again).Ash directly falls into reducer pipe, opens electric butterfly valve (source of the gas) when ash is long-pending earlier to certain altitude, opens pneumatic wear resistance ball valve again, opens pneumatic clock-type unloading valve at last ash is entered big grey storehouse.Subsequently according to opening sequence oppositely close each equipment, so just finish the ash discharge process one time.Ash amasss behind certain altitude in big grey storehouse, then opens humidifier and manual push-pull valve, and ash is transported by automobile.
The normal defeated grey high pressure purified gas that adopts, nitrogen are as the usefulness of ftercompction, and accident conditions adopt nitrogen to carry (gas of discharging in the ash storehouse when adopting nitrogen to fail ash directly enters atmosphere).The work that goes round and begins again like this, the dust of collection is sent after dust-laden coal gas (being raw coke oven gas) is fully purified by constantly diction filter and discharge.Blast furnace gas utilization bag-type dust, temperature controlling is most important.The temperature height makes the cloth bag embrittlement easily, will influence cloth bag life-span and coal gas dust removal effect.Also different according to material different temperatures control range, need the device of controlling gas temperature.
Adversary's blast furnace gas dry method pulsed jet cloth filter must strictly be controlled the gas temperature that enters deduster, 180-200 ℃ of the normal serviceability temperatures of deduster, the temperature maximum temperature should be less than 280 ℃ before raw coke oven gas entered the dry method pulsed jet cloth filter, when arriving high-temperature, blast furnace system should be taked cooling measure, gas temperature is controlled in the normal temperature range, guarantees the normal use of filtering material.Long-time (surpassing 10min) surpassed more than 280 ℃, and blast furnace must be taked the measure of diffusing, in order to avoid burn out filter bag.
Summary of the invention
The purpose of this utility model is to provide a kind of blast furnace gas dry pulsed jet cloth filter heat sink, and the temperature that enters the sack cleaner blast furnace gas is controlled in the rated range, prolongs the service life of filter bag, guarantees the sack cleaner operate as normal.
The purpose of this utility model is achieved in that a kind of blast furnace gas dry pulsed jet cloth filter heat sink, comprise the raw coke oven gas pipe, the sleeve pipe of closed at both ends in the outer setting of raw coke oven gas pipe, in sleeve pipe the raw coke oven gas pipe above the shower that axially is evenly equipped with hole for water spraying is being set, be positioned at the delivery port that the sleeve pipe bottom is provided with and connecting recovery tank, connecting the shower that is positioned at sleeve pipe by the water-supply-pipe that water pump is housed at the delivery port of recovery tank by outlet pipe.
During the utility model work, on the inlet tube of raw coke oven gas pipe connection sack cleaner, temperature measurer is installed, temperature measurer is connecting Control System of Microcomputer by lead, raw coke oven gas temperature in managing is monitored, when the gas inlet temperature is higher than 260 ℃, send alarm signal, open the water-in and water-out electromagnetic valve simultaneously automatically.Start water pump system, begin raw coke oven gas is carried out spraying cooling.When the gas inlet temperature is reduced to 180 ℃, stop water pump system automatically, close the water-in and water-out electromagnetic valve, finish the work of raw coke oven gas pipeline spraying cooling.Because the heatproof temperature of beautiful this FM9806 of filter pocket material fluorine is 260 ℃, the gas inlet temperature is higher than 260 ℃, then sends alarm signal, and the raw coke oven gas pipe is carried out spraying cooling, guarantees that the temperature of blast furnace gas is moved in rated temperature range.Therefore, the utility model can make the temperature that enters the sack cleaner blast furnace gas be controlled in the rated range, has prolonged the service life of filter bag, guarantees the sack cleaner operate as normal.
