It removes particulate smoke and dust in the flue gas emitted by burning stoves or oil-fired boilers, thereby greatly reducing the amount of smoke and dust discharged into the atmosphere. This is an important environmental protection equipment to improve environmental pollution and improve air quality.
The main structure of the electrostatic precipitator is a steel structure, all welded by section steel, and the outer surface is covered with skin (thin steel plate) and insulation materials for the convenience of design, manufacturing and installation. The structural design adopts a layered form. Each piece is composed of several frame-type main beams, and the pieces are connected by large beams.
In order to install the skin and insulation layer, secondary beams are welded between the main beams. For such a huge structure, how to connect them in kind will require a huge workload and number of units.
According to the actual design requirements of the project and the main structural design of the electrostatic precipitator, the structural strength, structural stability and maximum displacement of the main beam of the suspended cathode plate are mainly examined.
For local areas, we mainly investigate the fatigue damage of the connection between the cathode plate and the main beam under long-term periodic impact; the optimal frequency selection of smoke and dust shedding on the cathode plate; the structural surface skin under wind load ( Thin plate) is connected to the main and secondary beams and the optimal choice of stiffness between them, etc.
Extended information
Thermal power plants use fuel to generate heat, heat water, and form high-temperature and high-pressure superheated steam. Then the steam enters the steam turbine along the pipeline and continuously expands to perform work and impact. The turbine rotor rotates at high speed, driving the generator rotor (electromagnetic field) to rotate. The stator coil cuts the magnetic lines of force and emits electric energy. The step-up transformer is then used to raise the voltage to the system and is connected to the grid to transmit electric energy to the outside. Finally, the cooled steam is further boosted by the feed water pump and sent back to the boiler to repeat the above cycle process.
Thermal power generation is a power generation method that uses the heat energy generated when combustible materials are burned and converts it into electrical energy through a power generation device. China is rich in coal resources. In 1990, it produced 1.09 billion tons of coal, of which only 12% was used for power generation. Thermal power generation still has huge potential.
The power generated by thermal power stations brings many other by-products and has many environmental impacts. According to the principle of Carnot cycle, there is always a part of waste heat that must be discharged to the atmosphere through cooling towers or cooled by water bodies such as natural rivers.
The flue gas after burning fossil fuels will be emitted into the atmosphere. Its main components are carbon dioxide, water vapor, and other components such as nitrogen, nitrogen oxides, sulfur oxides, etc. If coal power generation factory, there will also be fly ash, mercury, etc. The residue after burning coal must also be removed from the boiler, and some can be recycled to make building materials.

Most power plants use thermal energy to generate electricity. The fuels they use include coal, oil and natural gas. wait. Thermal power plants can provide large amounts of electricity, but they cause environmental pollution. Some power plants use the heat generated by nuclear reactions to generate electricity. Nuclear power plants produce large amounts of electricity, but they leave behind nuclear waste.
Some power plants do not requireFuel can also be used to generate electricity, such as: solar power plants, which use the thermal energy of the sun to generate electricity; geothermal power plants, which use the thermal energy of the ground to generate electricity; hydroelectric power plants, which use the drop of water to generate electricity; wind power plants, which use wind power to generate electricity; tidal power plants, Using tidal energy to generate electricity, the bad news is that these energy sources cannot currently meet all of our human electricity needs; the good news is that humans can find better ways to obtain pollution-free energy.
