Description

An enhanced dust removal control device based on diatom mud

technical field

The utility model belongs to the field of electronics, in particular to an enhanced dust removal control device based on diatom mud.

Background technique

With the continuous rapid development of industry and agriculture, air pollution has become more and more serious. In recent years, people have a deeper understanding of the environmental impact of air pollution, especially the increased attention to PM2.5. PM2.5 refers to particles with an aerodynamic diameter of less than 2.5 μm, which can absorb various toxic substances and then directly enter the lower respiratory tract of the human body. The harm of PM2.5 has been proved by medical research to be related to various respiratory diseases. Many countries have carried out monitoring of PM2.5.

From the perspective of people's livelihood, reducing PM2.5 is a goal that must be achieved. Iron and steel, thermal power and other enterprises are the main sources of PM2.5. For the governance of PM2.5, it is more difficult. The effect of the usual electrostatic dust removal method is not ideal.

Current studies have found that diatom mud has an adsorption effect on fine particles. Diatom mud is a kind of biogenic siliceous sedimentary rock. It is composed of the remains of ancient diatoms, and its chemical composition is mainly SiO ₂ , in addition to a small amount of Al ₂ O ₃ and so on. It is mainly used as adsorbent, filter aid and decolorizer. The special porous structure of natural diatomite can be observed under the microscope, and the electron microscope shows that there are countless tiny holes on the particle surface, the porosity is over 90%, and the specific surface area is up to 65m ² /g. Its ultra-fine pores are 5000 to 6000 times more than activated carbon. It is this outstanding molecular sieve structure that determines its unique function, which has strong physical adsorption performance and ion exchange performance.

If diatom mud is used as the first level of electrostatic dust removal, it will soon be filled with soot particles and lose its dust removal function. It can only be used as the soot that is not up to standard after the first stage of dust removal, which can prolong the use time of diatom mud and reduce the cost of dust removal. When to use diatom mud layer for dust removal is an urgent problem to be solved.

The utility model proposes an enhanced dust removal control device based on diatom ooze, which can automatically use diatom ooze to strengthen fine particles according to the dust removal effect of smoke. It not only prolongs the use time of diatom mud, but also achieves a better filtering effect on PM2.5.

The utility model is mainly used in the smoke and dust treatment of iron and steel smelting industry and thermoelectric enterprises.

The flue inlet, the first-stage cylindrical electrode plate, the second-stage cylindrical electrode plate, the diatom mud layer, and the sampling flue are all cylindrical. The first-stage linear electrode, the enhanced treatment channel solenoid valve, and the bypass solenoid valve are cylindrical.

The dust enters from the flue, and is processed by the high-voltage electrostatic field composed of the first-stage cylindrical electrode plate and the first-stage linear electrode, and some particles with larger particle sizes are removed. The treated smoke enters the flue through the bypass. Part of the smoke and dust will enter the sampling flue in the flue. The particle sensor monitors the smoke and dust in the sampling flue, and the monitoring signal is directly sent to the single-chip microcomputer. The single-chip computer compares the data sent by the sensor with the particle limit data in the memory. When the data sent by the sensor is greater than the particle limit data, the single-chip microcomputer sends an instruction. The solenoid valve motor of the enhanced treatment channel is connected through the resistor, the three-stage tube, and the relay, and the motor rotates to open the electromagnetic valve of the enhanced treatment channel, and the enhanced treatment channel is opened; at the same time, the single-chip microcomputer issues an instruction to close the bypass solenoid valve through the resistor, the three-stage tube, and the relay Motor power, under the action of the spring, the bypass solenoid valve is closed, and the smoke after the first electric field treatment can only enter the enhanced treatment channel. In the enhanced treatment channel, the soot is in contact with the diatom mud layer, and the soot is further purified by the adsorption of the diatom mud layer. The electric field formed by the second-stage cylindrical electrode plate and the second-stage linear electrode connected to the diatom mud layer makes Part of the particles that are easy to charge move to the diatom mud layer and are removed by adsorption, and the smoke and dust in the enhanced treatment channel enters the flue and is discharged.

The beneficial effect of the utility model is that diatom mud can be automatically used to strengthen fine particles according to the dust removal effect of smoke, which not only prolongs the use time of diatom mud but also achieves a better filtering effect on PM2.5.
