The main contents of the installation project layout plan include: 1) the utilization principles of the installation site and its temporary works centered on the dust removal equipment; 2) Installation location and range of impact of lifting equipment; 3) The stacking of prefabricated components and the distribution of material and equipment warehouses; 4) Component assembly and temporary production location; 5) Construction water, electricity, and transportation road facilities; 6) Construction site and security facilities; 7) On site office and staff accommodation arrangements.
The construction organization design for installation engineering should include: (1) planning, setting installation engineering goals, relying on technological innovation, enriching technology, fully utilizing human, material, and financial resources, coordinating arrangements, and formulating dust removal equipment installation goals. This is the core indicator of installation engineering construction organization design and the basis of goal management, achieving effective indicators, measures, and resources. (2) Develop installation plans with clear guiding principles, supporting measures, orderly management, and flexible operation. The installation plan should have clear installation techniques, organized measures, continuous quality control, and effective operation management. (3) Planning and utilizing the overall layout of the installation project is the battlefield for dust removal equipment installation. Its planning and utilization directly reflect the strategic deployment of its installation project planning, the dynamic operation of manpower, material resources, and financial resources, as well as the supply routes of construction water, electricity, and road transportation. A thriving construction scene will be displayed and become the battle map for organizing the installation project. Approval or recognition from the construction unit for the installation project's overall layout plan.
The bag filter is mainly a device that relies on mechanisms such as inertial collision, screening, and interception between filter media and dust particles to achieve gas-solid separation. The filtering wind speed, filter material performance, back blowing cleaning method, and cleaning system have a significant impact on dust removal efficiency and resistance. Therefore, in the design of dust collectors, in addition to selecting suitable filter media based on the characteristics of smoke and dust, and determining a reasonable filtration wind speed, the following points should also be noted in processing and manufacturing. (1) The connection between the filter bag and the flower board should consider both easy disassembly and assembly during bag replacement, as well as tight and leak proof measures to prevent airflow short circuits and reduce dust removal efficiency. (2) When using an external filter, the surface of the cage bone supporting the filter bag should be flat and smooth, without sharp protrusions or burrs, to prevent puncturing or rapid wear of the filter bag, which may cause airflow short circuits and reduce dust removal efficiency. (3) When using an internal filter, the upper suspension mechanism should be aligned with the lower flower plate, and the filter bags should have sufficient verticality and equal bag spacing. The tightness of the filter bag lifting should be consistent to prevent excessive deformation of the filter bag, which may affect the normal operation of the dust collector. (4) Pulse valves, solenoid valves, and pulse control instruments used for pulse cleaning are required to have good performance, flexible operation, and the ability to operate continuously for a long time. (5) The reversing valve and its control device that use atmospheric reverse suction or reverse blowing for dust cleaning are in place, flexible in action, easy to operate, and tightly sealed without air leakage when closed.
