Dust collector process description
The filtering principle of the dust removal framework:
Dust collector skeleton common problems and solutions:
What is the effect of the bag dust collector? Novo environmental protection has produced dust collectors for many years. Professional technicians will answer your questions.
There are two types of traditional dust removal methods for filter cartridges, one is high pressure air blowback, and the other is pulse air blow. Practice shows that the former has the advantage of uniform air flow and the disadvantage is large air consumption.
It is relatively difficult for the bag filter to deal with special nature dust, and corresponding measures need to be taken:
During use, it is necessary to prevent the gas from cooling below the dew point in the bag room, especially when using a pulse dust collector under negative pressure.
How to choose a suitable pulse bag type dust collector, Novo environmental protection 20 years old factory patiently answer:
The role of the bypass valve device on the dust collector, Novo Environmental Protection introduces you:
The processing air volume of a 1 ton salivary boiler bag filter is 3000m3 / h. If we calculate it according to the discharge depth of 30 mg per cubic meter, the internal filter wind speed of the dust collector should be selected at 0.6-0.8m / min. Calculated by 0.6, the filtering area of this equipment is 83 square meters, and the filtering area of a 133 * 2000 dust-removing cloth bag is 0.8 square meters. Then, the equipment of this dust collector should be a 100-bag dust collector.
The filter bag should be made of organic chemical (synthetic) fiber filter cloth and twill weaving method, which has wear resistance, heat resistance, anti-condensation, strong air permeability, small pressure loss, low absorption rate, high strength, light weight, and acid and alkali resistance. , Anti-corrosion and other characteristics, the service life of the filter bag should exceed 15000 hours.
The unloader is also called star-shaped unloader, electric ash discharge valve, rotary feeder, air lock valve. There are two main ways of importing and exporting flange connection of star discharger, square mouth is A type, round mouth is B type. The other is a chain star-type unloader. This type of unloader is resistant to high temperature and cost-effective. The model of the unloader can be divided into two series of YJD and XLD. Although the series are different, the structure is similar. The unloading device is divided into three parts. (X) and rotary dragon ash discharge valve, there are four series, 48 kinds of specifications. Although the specifications of the unloader are diversified, the factors that affect the price are mainly a few:
The fan of the positive pressure bag dust collector is installed in front of the bag dust collector. The fan draws out the wind from the interior of the dust collector to carry out the dust collector. This fan is in front of the dust collector to ensure that there is no particulate matter in the incoming smoke If there are large particles, it is easy to cause damage to the fan motor. In addition, it is best not to have corrosion in the dust introduced by the fan. If the content of the corrosion component is too much, the service life of the dust collector fan will be greatly damaged.
Venturi tubes are provided at the positions of the dust removal frame. In this way, even if the blowing holes of the bag dust collector are distorted, the blowing air stream will not directly blow onto the bag. This air stream will be blown onto the venturi tube and then returned to the bottom of the skeleton. This venturi tube serves as a protective dust bag and guides the wind.
The spray tower has low maintenance cost and good use effect. After using the spray tower for a period of time, there will always be some small problems. What are the causes of these problems, and how should we solve them, this is the concern of customers. Xiao Zhao will give you a detailed analysis and explanation.
