What are the requirements of industrial dust collectors on thermal insulation technology?
First, the industrial dust collector insulation material must be satisfied with the insulation function to ensure that after the insulation (the ambient temperature is not higher than 25 degrees, the external surface temperature of the thermal insulation structure does not exceed 50 degrees; when the ambient temperature is higher than 25 degrees, the external surface temperature of the thermal insulation structure is comparable to the environment 25 degrees higher). The thermal insulation structure should be intact during the design service life, and it is not allowed to burn, rot, peel and other phenomena during use. The thermal insulation structure should have sufficient mechanical strength so as not to be damaged under the effects of self-weight, vibration, wind and snow and other additional loads.
Second, the insulation layer should be waterproof, fireproof, and the overall plane is flat and beautiful after the insulation (the ribs are not leaked after the insulation, and the ribs are flush with the outer shield, and the outer layer is provided with a heat insulation structure of the air movable layer).
Third, take reliable measures especially at the ribs to ensure that they are not overheated.
Fourth, the thermal insulation construction can only be performed after the dust collector has undergone air tightness inspection or experiments.
Fifth, the insulation is used in any weather conditions, so the laying of the shell protection board is conducive to water drainage.
6. The insulation structure requires no less than 8 self-locking gaskets per square meter, and the horizontal spacing of the cored aluminum rivets is 200MM.
7. The thickness of the thermal insulation layer is 100MM, and the reinforcing ribs are 50MM. The thermal insulation material is high-temperature glass wool (TYPE1000, δ = 50), which is laid in two layers in the thickness direction, and the gaps between the layers should be not less than the board. The length or one third of the board width should be tight and flat. The outer layer of high-temperature glass wool should be laid with galvanized hexagonal wire mesh, and then pressed with self-locking gaskets. A steel mesh is laid at the small ash hopper at the lower part of the ash hopper, and then pressed by a self-locking gasket.
8. Industrial dust collectors are often used for doors, and the heat insulation at the transmission does not affect the opening of the door and the operation of the equipment.
Nine, 5 * 13-11 cored aluminum rivets are used when the shell protection plate is connected to the connecting angle steel, and 5 * 11-11 cored aluminum rivets are used when the protective plate is connected to the protection plate.
Ten, the distance between the support angle of the upper and lower directions is about 1000MM, the distance between the left and right directions is about 500MM.
