Abstract
The utility model discloses a pressure adjustable positive pressure pneumatic conveying device comprising a group of dust collector box bodies, the dust collector box bodies are connected to an ash storage silo by a conveying pipeline of a valve control group, and two pipelines for conveying ash conveying media are arranged in parallel on the conveying pipeline. The pipelines for conveying the ash conveying media are the pipelines for conveying one of nitrogen and high-pressure clean gas. The pressure adjustable positive pressure pneumatic conveying device improves the ash conveying ability of pneumatic conveying of a blast furnace gas dry bag filter, reduces the energy consumption and leads the pneumatic conveying to be effectively used in the blast furnace gas dry bag filter and obtain the popularization.
Description
Technical field
The utility model relates to a kind of adjustable-pressure malleation Pneumatic conveyer.
Background technology
The defeated grey mode of deduster has two kinds at present: a kind of for the machinery conveying, and mainly contain conveying worm or embedded scraper transporter dust is transferred out dust pelletizing system; Another kind is carried for strength, utilizes gas to do carrying, carries by pipeline.Compare with the machinery conveying, strength carry have good airproof performance, environmental protection, investment is little, fault is few, the advantage of defeated grey process non-secondary pollution and gas leak, strength is carried does not simultaneously have middle ash bucket, can reduce the absolute altitude of whole deduster, not only reducing investment outlay but also increased security, is development trend from now on.
Strength is carried and is divided the suction type strength to carry and the conveying of positive-pressure type strength, the application that the suction type strength is carried on the environmental dust removal device is wider, strength conveying at the blast furnace gas drying bag dust removing device is the conveying of positive-pressure type strength, just brings into use in recent years, and its result of use is undesirable.
Positive-pressure type strength in the blast furnace gas drying bag dust removing device is carried at present, has following defective:
(1) pressure fixing of defeated grey medium can not be regulated, and causes the dust in the defeated ash dust collector ash hopper in early stage should not be discharged in the ash conveying pipe the defeated grey speed of impact; Being short of power appears in the defeated ash later stage easily, when the water content of dust is big, stops up easily ash conveying pipe.
(2) in the course of conveying in the pipeline dust concentration low, belong to dilute phase and carry, ash conveying pipe is easy to wear, particularly elbow, to unload grey threeway place very short service life.
(3) gas consumption is big in the defeated grey process, and gas-solid ratio is low, and defeated grey ability is low.
(4) adopt nitrogen as defeated grey medium merely, consume a large amount of energy.
Summary of the invention
The purpose of this utility model provides a kind of positive-pressure pneumatic conveying apparatus with adjustable pressure, and it can make pneumatic transporting send in the blast furnace gas drying bag dust removing device and effectively be used, and obtains promoting.
For achieving the above object, the utility model is taked following design plan:
A kind of positive-pressure pneumatic conveying apparatus with adjustable pressure comprises one group of dust collector box body, and dust collector box body is communicated to ash-storing bin through the conveyance conduit of valve control group, on conveyance conduit and establish two ash transportation pipelines, can alternately pass into defeated grey dielectric gas.
Described ash transportation pipeline is a kind of defeated grey medium pipeline in supplying nitrogen, the high pressure purified gas.
The utility model has the advantages that: improved the defeated grey ability that blast furnace gas drying bag dust removing device strength is carried; Effectively reduce pipe wear; Long service life, to the adaptive capacity enhancing of dust variable working condition, energy resource consumption reduces.
Description of drawings

The specific embodiment
As shown in Figure 1, the utility model adjustable-pressure malleation Pneumatic conveyer comprises one group of dust exhaustor casing 6, and the dust exhaustor casing is communicated to ash-storing bin 7 through the delivery duct 4 of valve control group through elbow 5.
Innovative point of the present utility model is: on conveyance conduit and establish two ash transportation pipelines, one is supplying nitrogen pipeline 1, and another is conveying high-pressure purified gas pipeline 2.Be energy savings, the refuse change is precious, the high pressure purified gas of carrying is the coal gas after the blast furnace gas drying bag dust removing device purifies, and the pipeline of conveying high-pressure purified gas and the gaspipe line after the purification of blast furnace gas drying bag dust removing device are connected.Nominal situation adopts blast furnace gas down, adopts nitrogen under the maintenance operating mode, can switch flexibly between the two.
For overcoming ash conveying pipe problem easy to wear, the utility model adopts defeated grey abrasion-proof pipe (comprising straight pipeline 4 and elbow part 5).To its structure and wear-resisting aspect process, at inner-walls of duct plating wear-resistant ceramic, and in elbow and threeway place optimal design, to increase its dust conveying capacity and anti-wear performance.
For realizing adjustable defeated grey pressure medium gas, can increase by a cover pressure flow control system on the path before defeated grey medium enters ash conveying pipe, comprise control valve, pressure detecting, volume control device, it is prior art, this does not give unnecessary details.
Operation principle of the present utility model and process: adopt the high pressure purified gas as pumped (conveying) medium, be transported to dust in the ash-storing bin after, with its purification and be recovered in the low-pressure gas pipe network.The pressure energy of the defeated a small amount of blast furnace gas of grey process utilization does not consume other energy, compares with the defeated grey medium of nitrogen conduct, can save mass energy, reduces production costs.
The pressure of defeated grey medium is along with what and dynamic change of dust in the ash conveying pipe, automatically adjust in the bound of setting by the pressure flow regulating system, through constantly revising, how many pressure medium, flows of defeated ash are adjusted with ash amount in the ash conveying pipe, significantly improve the gas-solid ratio in the defeated grey process, increased unit interval conveying dust ability.At the defeated grey initial stage, it is few to be discharged into the interior dust of pipeline, and it is low regulating defeated grey pressure this moment, and it is few that grey medium is failed in use.Dust can be transported in the ash-storing bin like this, save again defeated grey medium, also be convenient to dust and be discharged in the ash conveying pipe.Dust increases in the defeated ash middle and later periods pipeline, forms piston-shaped, and this moment, defeated grey pressure medium was heightened, and was convenient to carry, and prevented from stopping up.
Along with the adjusting of pressure, the flow of defeated grey medium is also done corresponding adjustment, can save to greatest extent so defeated grey medium, increases the gas-solid ratio of the mixture in the ash conveying pipe, improves transportation concentration.
The ash conveying pipe elbow and unload threeway that ash goes into ash conveying pipe structure and wear-resisting aspect process, at inner-walls of duct plating wear-resistant ceramic, and optimal design elbow and threeway, big leap ahead the service life of ash conveying pipe, the original ash conveying pipe that will change in two, three months uses more than 1 year now, has improved the reliability of ash-transmission system.
The various embodiments described above can not break away from addition some variations under the scope of the present utility model, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit claim of the present utility model.
