Abstract
The utility model provides a gravity dust collector ash handling equipment that beats water connects an ash storage tank below the ash handling valve of cone lower extreme under the gravity dust collector, and an blast pipe that has discharge valve and at least 2 water guns are installed respectively on ash storage tank upper portion, and waste gas recovery jar or waste gas pipeline are connected to the blast pipe other end, and the water gun passes through stop valve and high pressure water piping connection, is equipped with the unloading valve on the ash storage tank lower extreme ash pipe. The stop valve and the ash valve are opened at the same time with small opening degree, and the opening degree of the stop valve is adjusted along with the increase of the opening degree of the ash valve, so that the pumped water fully wets the gas ash; when the gas ash completely enters the ash storage tank, closing the water injection gun and the ash injection valve; and closing the exhaust valve after the high-pressure coal gas in the ash storage tank is exhausted, and opening the ash discharge valve to discharge ash. The utility model discloses can effectively prevent to beat the diffusion of ash in-process dust and poisonous and harmful gas, avoid environmental pollution, improve the operation environment, when guaranteeing that the operation personnel is healthy, improve the efficiency of tapping and slagging operation.
Description
Technical field
The utility model belongs to Environmental-protecting dust-removing technical field, particularly relates to a kind of fetch water ash handling equipment and method for gravity blast furnace dust catcher.
Background technology
At present, the whole world is faced with the serious large problem of environmental pollution, and the associated enterprisess such as domestic and international each big steel, coal, chemical industry for mines want normal production, just must ensure can carry out under prerequisite free from environmental pollution.Traditional gravity blast furnace dust catcher plays in grey process the dual pollution that can cause dust and toxic and harmful, grey measure is put even if take high pressure to fetch water, also can only be the quantity discharged reducing dust, and reach more than 40 minute beat in grey process, the blast furnace gas pollution on the environment of high pressure cannot be avoided at all.
Beating in grey operation process in the past, owing to discharging coal gas continuously in the air near extractor displacer, cause blast furnace discharge yard near the gas content severe overweight of extractor displacer position, directly have influence on the slagging operation of tapping a blast furnace of stokehold workman, slag iron can not go out the steady running that only also can have influence on blast furnace in time, and then affects blase furnace cast iron output and production cost.More seriously, to exceed standard regional work at coal gas for a long time, not only endanger the healthy of operating personnel, also will cause gas poisoning, directly jeopardize the life security that tank personnel lowered by stokehold workman and stove.
Summary of the invention
The utility model aims to provide a kind of gravitational precipitator that prevents and is beating diffusing of dust and toxic and harmful in grey process, thus avoids environmental pollution, and the gravitational precipitator improving operating condition is fetched water ash handling equipment and method.
For this reason, the technical solution that the utility model is taked is:
A kind of gravitational precipitator is fetched water ash handling equipment, a bulk cement storage tank is connected beating below grey valve of gravitational precipitator lower cone lower end, bulk cement storage tank top is separately installed with a vapor pipe with vent valve and at least 2 rifles of fetching water, the vapor pipe the other end connects waste gas recovery tank or exhaust pipeline, rifle of fetching water is connected with high-pressure water pipeline by stopping valve, and bulk cement storage tank lower end cement output tank is provided with unloading valve.
Process for deashing and the beneficial effect of fetching water of the present utility model is:
When beating ash, rifle stopping valve of fetching water is opened to 1/3 and is fetched water, and opens lower cone lower end simultaneously and makes grey valve, beat grey valve opening and control 10 ~ 30%, and gas ash falls into gradually in bulk cement storage tank under the dual function of self gravitation and high pressure gas; Along with the increase of beating grey valve opening, rifle stopping valve aperture of fetching water also synchronously strengthens thereupon, makes the abundant moistening gas ash of water got; After the gas ash in gravitational precipitator all enters bulk cement storage tank, close and fetch water rifle and make grey valve; After a small amount of high pressure gas remained in bulk cement storage tank imports waste gas recovery tank or exhaust pipeline via vapor pipe, close vent valve; Open bulk cement storage tank lower end unloading valve, under atmospheric pressure state, gas ash is discharged in bulk cement truck skin.
The utility model can effectively prevent gravitational precipitator from beating diffusing of dust and toxic and harmful in grey process, thus avoid the environmental pollution that dust and toxic and harmful cause, greatly improve operating environment, while guarantee operating personnel is healthy, improve efficiency and the quality of slagging operation of tapping a blast furnace, be conducive to the direct motion of blast fumance.
Accompanying drawing explanation
Fig. 1 is that gravitational precipitator is fetched water ash handling equipment structural representation.
In figure: bulk cement storage tank 1, stopping valve 2, rifle 3 of fetching water, fly-ash separator lower cone 4, beat grey valve 5, vapor pipe 6, vent valve 7, waste gas recovery tank 8, unloading valve 9.
Embodiment
As seen from Figure 1, the utility model gravitational precipitator is fetched water ash handling equipment, comprises bulk cement storage tank 1, stopping valve 2, rifle 3 of fetching water, beats grey valve 5, vapor pipe 6, vent valve 7, waste gas recovery tank 8 and unloading valve 9.Namely connect a bulk cement storage tank 1 beating below grey valve 5 of fly-ash separator lower cone 4 lower end, the top of bulk cement storage tank 1 is provided with a vapor pipe 6 with vent valve 7, and the other end of vapor pipe 6 connects waste gas recovery tank 8, also can be connected with exhaust pipeline.Meanwhile, 4 rifles 3 of fetching water also are equipped with on the top of bulk cement storage tank 1, and rifle 3 of fetching water is connected with high-pressure water pipeline by stopping valve 2, and the cement output tank of bulk cement storage tank 1 lower end is provided with unloading valve 9.
The utility model is beaten in grey process at whole gravitational precipitator, does not both have dust pollution, does not also have gas pollution, can guarantee that environment is up to standard, meet the idea of development of modern plant energy-saving and emission-reduction, environmental protection, cleaner production, safety and Health.
