Bag filter supplier: How to reduce the temperature of a baghouse dust collector?
Author：
Bag filter supplier Indicates, When using bag dust collectors, it is often necessary to operate in a high-temperature environment. How should we reduce the temperature in such situations? Let's briefly introduce it below:
1. For continuously high-temperature dust gas cooling, low-temperature air or water can be used for air cooling or water cooling. Both air cooling and water cooling can achieve cooling, which is indirect cooling. These methods can help cool the dust and subsequently reduce the temperature of the dust collector.
Various cooling methods are applicable to different ranges, and their main characteristics are used in dust collectors with different temperatures and applications.
2. Appropriately add some ultra-low-temperature dust. If the gas temperature is inconsistent in the same dust removal system, an effective method is to first add some ultra-low-temperature gas to the high-temperature gas. Continuously adding cold air to mix with the gas can prevent the temperature in the dust collector from becoming too high.
3, Bag filter supplier indicates, There is another way to reduce the temperature of the dust collector, which is to install a cold air valve. After installing the cold air valve, the cold air valve can be installed before the bag dust collector to prevent high-temperature dust gas from exceeding the specified temperature and entering the bag dust collector. The cold air valve is a regulating valve with one end connected to the high-temperature pipeline and the other end connected to the outside air. The valve should be operated by an automatic high-temperature signal to control the amount of air drawn into the flue gas system, thereby reducing the gas temperature to the adjustable range.
Where is the bag dust collector prone to damage?
Bag filter supplier indicates, One reason is due to the filtration wind speed. If the filtration wind speed is increased, this can reduce costs, and the increased profit margin is not immediately noticeable to the customer because the increase in dust removal wind speed may bring about certain negative impacts. However, if the filtration wind speed is increased without following the standards, it may increase the customer's investment, and when problems occur later, it will also bring great economic pressure, requiring a lot of time to solve these problems.
For bag dust collectors, it is necessary to pay close attention to the selection of materials, because different materials have different application scenarios and service lives. Bag dust collectors use a variety of materials, and the selection should consider the specific environment, such as whether the dust contains acids, alkalis, or corrosive gases. When selecting materials, it is necessary to ensure that the materials can operate normally, absorb dust, and not have a shortened service life due to the external environment.
The bags of the bag dust collector may also be damaged due to the influence of ambient temperature, and the degree of damage varies. If the ambient temperature is very high, and the selected dust bag exceeds its normal operating temperature, its service life will be reduced, and in severe cases, it may even burn out in a short period. Therefore, the applicable ambient temperature of the bag dust collector should be considered. The inlet temperature should be tested or calculated to select a dust bag that can withstand the ambient temperature.
The company mainly produces various dust removal, desulfurization, denitrification, VOCs waste gas purification, wastewater treatment, noise reduction, complete sets of industrial electrical control systems and equipment, and researches and develops waste gas, wastewater, waste residue, and noise treatment equipment.
