Dust mine ventilation

Introduction

Dust mine ventilation is composed by mine ventilator with a wet vibrating wire catching dust components. Dust-laden air is inhaled dust blower, after wet vibrating wire catching dust capture the dust, local dust purification, purification of air from the dust after catching dust exhaust outlet, to purify romantic purposes. The Dust Blower for mechanized excavation face, boring job in situ dust dusty air purification, can also be used to coal, rock roadway, shotcrete face drilling, blasting the workplace.

working condition

1、Environment temperature 0～40℃；

2、Altitude less than 1000 meters；

3、Relative humidity less or equal（95±3）％（25℃）；

4、Used in methane and coal dust explosive gas underground；

5、Atmospheric pressure：（80～110）KPa。

Advantages

Mine Wet Dust Ventilation has unique properties and characteristics. Manifested in the following aspects:

1, the principle of unique, small size, light weight, use a dust removal mechanism with a variety of "vibrating wire filter plate" means catching dust through the filtration velocity can be increased to 10-18m / s, and with the efficiency of catching dust was positively related characteristics, so that unit air volume occupied by a minimum of space, similar products only 10% to 40%.

2, the working low resistance, low energy consumption: working resistance 1200Pa, unit energy consumption of air volume about 30% of similar products.

3, dust, high efficiency, suitable for a wide range of dust concentration, measured when the dust concentration 24000mg/m3, can still work without clogging, low concentrations of dust and gas purification effect is equally satisfactory. Dust particle can capture a wide range of coarse dust and respirable dust catching dust has a high efficiency.

4, simple structure, no cleaning cycle, "vibrating wire filter plate" self-purification ability, long-term continuous operation, do not plug without removing the cleaning and maintenance, simple structure, easy to use.

Technical index

1, total dust collection efficiency: ≥ 97%;

2, respirable dust collection efficiency: (90 ~ 98)% (positive correlation with the filtration velocity characteristics);

3, the liquid-gas ratio: (0.02 ~ 0.09) L/m3 (air volume) (by air dust concentration level may be);

4, most of the dust blower fan static efficiency of not less than 55%;

5, the working resistance: 1200Pa (with rated working resistance shall not deviate more than 10%);

6, applies to spray water pressure: ≥ 0.3MPa;

7, for the environment temperature :0-40 ℃;

8, work: long-term continuous operation;

9, Working noise: ≤ 85dB (A);

10 Dust concentration range: (0 ~ 24000) mg/m3 (air volume);

Shandong China Coal Industrial&Mining Supplies Group Co.,Ltd (hereinafter referred to as china coal) is a group company, which is a collection of e-commerce, machinery manufacturing, software, research and development, modern logistics of large diversified industrial group. The group has 100 million yuan registered capital , with more than 1100 employees.

China coal is a professional manufacturing base of mines support equipment, transport equipment, lifting equipment, spray equipment, drilling equipment, ventilation equipment, lifting equipment and other products, as well as research and development new product and mine construction products with advanced high technology.

In order to development of international trade , expansion overseas market, china coal established international trade branch company and import and export branch company. China coal actively expand foreign trade channels based on a good market image, brand, modern information platforms and capital protection. Based on the trading diversification strategy, the group established a chain loop trading system which is with import and export trade of the mining equipment as a core, the resources and market as the elements. China coal also formed a overseas sales team, that covers English, French, German, Portugal, Italy, Russian, Korean, Japanese, Arabic, and more than 10 language professionals to explore broader international markets on the Internet. At present, the group signed up for "china coal" trademark in the European Union, United States, Russia, United Kingdom, Taiwan, Macao, Singapore, Indonesia, Israel, and other countries, also get the right to use the trademark of the United Kingdom and Taiwan. Hundreds kinds of products such as tunnel boring machine, coal cutter machine etc. is exported more than 140 countries and regions which are the United States, Australia, Germany, Russia, Spain, France, Canada, United Kingdom, Italy, Portugal, Georgia, Austria, and Colombia. China coal is to establish long-term, broader economic and trade cooperation and strategic partnership with a number of large state-owned enterprises and customers, and won the unanimous approval of them.

China coal has succeeded in passing a number of certification systems which are ISO9001, 2008 quality management system certification, United States ANAB management system certification, United Kingdom international authoritative certification bodies UKAS quality management system certification, SGS certification (made in China), Alibaba GIS certification. She has also obtained a variety of honor which are China excellent enterprise of mechanical industry, China equipment manufacturing operation top 10 enterprises, national reputation for quality assured supplier, China credit certification system demonstration unit, national quality trustworthy product for conformity assessment, national consumer satisfaction units, China AAA level quality trustworthy enterprise and Chinese e-commerce company credit rating AAA level credit Enterprise.
