Advantages of small coal-fired boiler bag filter in dust removal
At the same time of industrial development, the pollution problems of various enterprises have also appeared. In order to reduce pollution, the use of dust collectors to recycle and reuse harmful dust solves the big problem of industrial pollution. Bag filter is a dust removal equipment widely used in the environmental protection machinery market. .
With the gradual increase of small and medium-sized coal-fired boiler enterprises, the polluted flue gas released from the boiler has gradually polluted people's healthy living environment. Small and medium-sized coal-fired boilers have spread all over the country, causing serious air pollution and serious pollution. In order to improve the health of people's own health, coal-fired boilers are common. Coal-fired boilers are the most suitable dust collectors for coal-fired boilers in the power and heating industries, and they have high dust removal rate. The environmental protection standard is not a bag filter.
When selecting the boiler bag filter, the influence of the change of the dust concentration of the boiler outlet and the change of the extension temperature on the bag filter should be considered first. The change of the soot concentration only causes the load of the filter bag of the bag filter, which leads to the change of the cleaning frequency. Automatic adjustment). The dust concentration is high on the filter bag, the corresponding dust removal speed is high, and the corresponding cleaning frequency is high, otherwise the cleaning frequency is low, and the emission concentration does not cause the change of the flue gas temperature to be too low, the condensation may cause the “paste bag†and the shell Body corrosion, the temperature of the flue gas is too high. The filter material allows the temperature to easily "burn the bag" and damage the filter bag. However, if the temperature change is within the temperature range of the filter material, the dust removal efficiency will not be affected. The temperature that causes adverse consequences is at extreme temperatures (accident/abnormal conditions), so effective protection against extreme temperature control must be provided for the baghouse. The physicochemical composition of the flue gas has no effect on the dust removal efficiency of the bag filter. However, if the flue gas contains components that are corrosive to all filter materials, it will directly affect the service life of the filter media.
The boiler bag filter has high dust removal efficiency, especially for the collection of heavy metal particles and submicron dust particles which have serious effects on the human body. In the operation of dust removal equipment, the dust removal efficiency can reach more than 99%, and the concentration of exhaust smoke can be stable below 50mg/Nm3, even up to 10mg/Nm3, and almost zero emissions. The bag filter has a small footprint and can be specially designed according to the requirements of the site. There is no high voltage danger in bag dust removal, and the safety of the person is increased.
The boiler bag filter has less steel consumption in equipment investment, and has a small footprint and can meet environmental protection and safety emission standards. It has been widely promoted and applied in the environmental protection machinery industry and air pollution environmental protection industry.
Disposable Piercing Guide - WPTC5
A Disposable Laparoscopic Trocar is a medical device used in minimally invasive surgery to create a small incision in the abdominal wall for the insertion of surgical instruments and a camera. It consists of a sharp, pointed tip that is inserted through the skin and into the abdominal cavity, and a sleeve that provides a pathway for the surgical instruments. Once the trocar is inserted, the sleeve is locked in place and the instruments can be inserted and removed through it. Disposable laparoscopic trocars are designed for single-use only to prevent the risk of infection and cross-contamination. They are available in different sizes and shapes to accommodate various surgical procedures.
