Anonymous users2024-02-13Blast furnace dust removal selection equipment can be classified as follows:
Mechanical vibration: a bag filter that uses mechanical devices (including manual, electromagnetic or pneumatic devices) to vibrate the filter bag and clean the ash.
There are two types of bag filters: non-chamber structure suitable for intermittent work and chamber structure suitable for continuous work.
Compartment backflushing: a bag filter that adopts a chamber structure, uses a valve to switch the air flow chamber by chamber, and forces the filter bag to shrink or bulge and clean the ash under the action of reverse airflow.
Nozzle backblowing: a bag filter (all non-chamber structure) that uses a high-pressure fan or compressor to provide back-blowing airflow, and blows back-blowing through a moving nozzle to deform and shake the filter bag and penetrate the filter material to clean the ash.
Combined use of vibration and backblowing: bag dust collector (both chamber structures) used in combination of mechanical vibration (including electromagnetic vibration or pneumatic vibration) and backblowing two ash cleaning methods.
Pulse injection type: a bag dust collector that uses compressed air as the power to clean the ash, uses the pulse injection mechanism to release compressed air in an instant, induces several times the secondary air to inject into the filter bag at high speed, makes the filter bag bulge sharply, and cleans the ash by relying on impact vibration and reverse air flow.

Anonymous users2024-02-12The main equipment of blast furnace gas dry dust removal includes gravity dust removal, cyclone dust removal, and bag dust removal.
1. At present, the mainstream method is to go through gravity dust removal or cyclone dust removal coarse filtration, and then enter the bag dust removal for fine filtration;
2. The process of using dry gas dust removal technology is mainly dry gas external filter bag dust removal, which is a mature technology developed in recent years, and is also the mainstream technology used in domestic gas dust removal, which is simple to operate, high dust removal efficiency, stable and safe operation;
3. The bag dust removal device is mainly composed of dust collector box, pulse backflush system, ash discharge system, valve, expansion joint, electrical, instrument and automatic control system.

Anonymous users2024-02-11Boiler dust collectors can be divided into steam dust collectors, bag dust collectors, boiler desulfurization dust collectors, vertical kiln bag dust collectors, etc.
The boiler dust collector is suitable for dust removal, smoke removal and desulfurization, which has the characteristics of low resistance, flexible installation and layout, high desulfurization efficiency and long service life!

Anonymous users2024-02-09According to the needs and nature of the dust removal setting, the blast furnace dust removal ash can be roughly divided into two categories: flue gas dust removal ash and environmental dust removal ash. Flue gas dust removal is necessary for the production process, such as the high-temperature flue gas of the sintering head, the dust removal of the blast furnace and the gas system of the rotary or old furnace, and this kind of dust removal ash is the flue gas dust removal ash.
Environmental dust removal is set up to reduce environmental dust pollution, such as dust removal in raw material loading and unloading, transfer and other positions, this kind of dust removal ash is environmental dust removal ash. Generally speaking, the environmental dust removal ash is the accumulation of slow branches at room temperature, and the nature of the medium dust is not greatly sensitized, which is relatively easy to use and basically has no harm to production. Hope it helps.
Wishing you a happy life and good health!
White tea is divided into: bud tea (such as Baihao silver needle) and leaf tea (such as white peony).
It is usually made into a flat, rectangular building material board of standard size and is used as a component of walls, ceilings or floors. It also refers to a metal sheet that has been wrought, rolled or cast. It is divided into thin plates, medium plates, thick plates, extra-thick plates, and flat rectangular building material plates that are usually made into standard sizes. >>>More
1. Subperiosteal dental implants, the most commonly used materials for this type of dental implants are cast cobalt-chromium alloy, and can also be sprayed with alumina, ceramics, etc. on its surface, which is often used for those whose alveolar bone width and height are not enough and it is difficult to use other intraosseous implants to achieve functional effects. It is mainly used for edentulous patients with upper and lower jaws, and the lower jaw effect is better. >>>More
