1. If there is a dust collector for the blow pipe, there will be dust on the blow pipe corresponding to the bag of the broken dust collector. This is easier to judge. The dust collector of the gas box pulse is not very easy to find. First look at which room has dust, and then look around the dust accumulation. There will be dust adhering to the bag mouth inside the broken dust collector bag. 2. Whether there is a slight positive pressure phenomenon in the sealed chamber or sealed space connected to the lower part of the dust hopper, if any, you can open the upper cover of the dust spray chamber and observe the bag hole of the dust collector. The dust is forced out by the micro-positive pressure, and the dust collector bag is broken. 3. If there is no micro-positive pressure working condition, the upper cover of the blowing chamber can be directly opened, and the fan can be operated. Observe that the bag hole of the dust collector is extracted, and the bag is broken. In the toxic gas environment, it is only the most simple and effective to check this way, and the operating time of the blower can be shortened. It is ok to throw a phosphor to catch the leak, but the price may be more expensive, but the effect is very good. In the field of bag dust removal, what kind of dusty flue gas can be treated by the bag filter depends mainly on the conditions of the chemical fiber itself used to make the bag. Therefore, we must have a method to check the performance of the dust bag, in order to choose the most suitable dust collector bag. For the dust collector bag, the contents to be verified and tested are as follows: 1. Mechanical properties: such as the breaking strength of the bag of the dust collector, the elongation at break, the elongation of the warp and weft load of the bag of the dust collector, and the bursting strength of the filter material. 2. Filter dust characteristics: such as drag coefficient, static dust removal efficiency, dynamic dust removal efficiency, dynamic resistance of filter material, regenerative drag coefficient and dust stripping rate. 3. Special functional characteristics: such as temperature resistance, corrosion resistance, electrostatic properties, hydrophobicity, etc. 4. Physical properties of the bag of the dust collector: such as the mass per unit area of ​​the bag of the dust collector, the thickness, the amplitude, the structure of the woven fabric, the density of the fabric, the bulk density of the nonwoven fabric, and the porosity. 5. Appearance inspection of dust collector bag: puncture, defect, black spot, jumper, broken wire, joint, etc. Under normal flue gas temperature conditions, only the dust collector bag can withstand temperatures below 150 ° C. In these occasions, chemical fibers such as polyester, polypropylene, acrylic, and nylon can be basically competent. The conical twin screw is different from the parallel twin screw in appearance. Its two ends have different diameters. The diameter of the feeding section is large, while the diameter of the homogenization section is small, and the middle is gradually transitioned. The conical twin-screw is a meshing type, and most of them are counter-rotating.

When we want to determine if the precipitator should change the bag of the duster, we should check whether the bag of the duster is broken: in fact, these should be very simple, open the access door above and directly view the upper and surrounding parts of the bag of the dust collector. The situation can be seen. The outlet of the intact dust collector bag and the damaged dust collector bag are definitely different. The cost of using the phosphor is too high. However, the method of observing the dust on the bag mouth of the dust collector in the above buildings cannot be accurately positioned. A damaged dust collector bag can only be circled to a smaller extent. During the operation, the gas chambers were manually closed one by one while observing the discharge port to determine the chamber after the ash leakage.
