Things to pay attention to when buying boiler bag dust collectors , The poor dust removal effect of the boiler bag dust collector is a more troublesome problem encountered by manufacturers in the later stage, because the procurement is based on the principle of meeting the procurement standards, and the subsequent emissions can not meet the requirements. This is really a big thing for people Therefore, it is necessary to carry out maintenance and renovation of the boiler dust collector, which is also something that the buyer does not know. Let us focus on several aspects of the analysis. I hope you can eliminate the current confusion and find and solve the root cause of the problem.
Things to pay attention to when purchasing boiler bag dust collector 1. Improper selection of dust collector for coal-fired boiler
Some companies are pursuing high quality and low price when purchasing boiler dust collectors. However, in reality, there is often no high quality and low price, which directly leads to the selection of bag dust collectors, which are too small, the dust removal effect is not good, and the filtering conditions are not good. Match. Therefore, when purchasing a dust collector, you must not only pursue the low price, but also choose an affordable one under the premise of ensuring the dust removal efficiency and emission concentration.
Things to pay attention to when purchasing boiler bag dust collector 2. Poor dust bag
The dust bag is an important part of the bag dust collector and plays a key role in the operation of the bag dust collector. The quality of the bag dust collector is very important. In recent years, some small manufacturers use small sewing machines as processing equipment and select secondary quality filter media (taking PPS filter media as an example, the price difference between PPS filter media and PPS composite filter media is 1/3). In addition, when processing, With inferior quality thread as raw material, the processing level is far behind. Choosing such a bag will naturally result in poor dust removal by the bag filter.
The above is the result of paying attention to the purchase of boiler bag dust collectors, the manufacturer's desire for cheap or being deceived by bad businessmen. Therefore, when buying products, you must pay attention to quality, and then emphasize the price.
One of the more important reasons to pay attention to the purchase of boiler bag dust collectors is that improper operation causes the boiler bag dust collectors to fail to achieve the expected results. This can be solved according to our process:
1. When shutting down the boiler, the dust collector must continue to clean the dust for at least two cycles to prevent condensation on the cloth bag for a long time. As a result, before the dust collector is closed, in addition to completely removing the dust, pay attention to the following points:
2. Pay attention to the condensation phenomenon when the temperature in the dust collector suddenly drops from high temperature to low temperature. After the production of the ore heating furnace is stopped, the dust removal fan will continue to run for a period of time to discharge moisture and replace dry air; in the room.
3. The dust removal fan stops running. After removing dust in the ash bin, perform maintenance on the fan and other transmission components;
4. During the long-term outage of the dust collector, regular short-term operation is a good maintenance method to ensure the normal operation of the dust collector system.
Boiler dust removal equipment transformation plan
It mainly includes adding a pre-dusting sedimentation chamber, expanding the foundation of the boiler bag dust collector, adding a sedimentation chamber, removing the original Jinfeng pipeline, and relocating according to, etc. The purpose of installing the sedimentation chamber is to prevent single-roller crushing and plate feeders The hot coarse particle dust generated at the discharge point enters the dust removal equipment to avoid damage to the bag and reduce the dust load on the bag filter. By installing a return baffle in the sedimentation chamber, the coarse particles in the airflow will slow down below the baffle. And when the dust air meets the baffle, it falls into the ash hopper below. In the construction of the additional sedimentation chamber, because of the cost considerations of the bag dust collector manufacturer, a buffer sedimentation area is usually added at the air inlet of the bag dust collector. Through the operation analysis, it is found that if the buffer subsidence zone is not added, the service life of the filter bag will be greatly shortened, thereby increasing the operating cost. In order to avoid the above problems, during the transformation of the boiler bag dust collector, The length of the box is increased in the structural design, and a buffer settlement area of 3 meters × 3 meters is added. The high-speed dust-containing airflow enters the bag dust collector. The buffer subsidence zone decelerates, allowing some coarse particles contained in the air stream to directly settle into the ash hopper, which effectively reduces the working load of the filter bag and extends the service life of the filter bag. The rising speed of the air flow in the bag filter needs to be controlled at a reasonable In the interval, avoid too large or too small to affect the use effect and service life of the bag filter.
