Shell heat preservation measures and pressure difference setting value of dust collector for dust removal and environmental protection equipment
During the operation of the dust collector, the program is mainly used to control the program. During the use of the dust collector, the program will start or stop signals such as its temperature and pressure difference. Triggered from the touch screen with a launcher.
After the pressure difference of the dust collector reaches the set value, its control system will effectively send a command to a group of electromagnetic pulse valves to perform effective dust removal in sequence according to the preset dust removal interval and dust removal sequence. After completion, its controller will set the resistance and value of the device.
If the resistance of the dust collector is lower than the set value in the process of use, the equipment will stop the dust removal, otherwise it will continue the dust removal. This type of operation can effectively protect the load change of the boiler to a certain extent, which can effectively The resistance of the equipment is effectively maintained within a suitable range.
When the start of the program is triggered in the dust collector, its inlet damper and outlet damper need to be opened one by one according to its certain time interval, so that after the inlet and outlet damper is fully opened, the side ventilation door needs to be closed during use. .
The dust collector is directly triggered manually by the operator during the normal shutdown process. If the inlet temperature reaches the high temperature maintenance set value or other maintenance conditions, the system in the equipment will actively execute the emergency state or the maintenance shutdown procedure.
The housing of the dust collector must adopt thermal insulation measures. Generally, the thermal insulation of the equipment needs to select materials with low thermal conductivity and good thermal insulation, such as aluminum silicate board, rock wool, and pearl swelled rock. Generally, it cannot exceed 0.23W / mK.
