Description

Intelligent wet dust removal equipment

Technical Field

The utility model relates to the field of dust removal equipment, in particular to intelligent wet dust removal equipment.

Background

Along with the gradual expansion and development of modern industrial construction in China, the domestic requirements for energy sources such as coal, electric energy, cement, steel, building materials and the like are synchronously increased, and a large amount of dust is generated in the production and transportation processes. The industries bring negative influence on the environment, a large number of enterprises are in extensive production, the production process and technology are relatively backward, the resource and energy consumption is large, the pollution is serious, and the quantity of generated dust and smoke dust is huge. The continuous deterioration of the environment is a great challenge for the continuous development of China, and the saving of the environment becomes a problem which is not negligible in the economic development of China. However, the operation cost is high due to the limitation of the existing dust removing and dust suppression technology, and the dust suppression effect is not ideal, so that the bottleneck of dust control is still existed, and the health of workers in the operation site with serious dust pollution is seriously damaged. The existing common dust removing equipment comprises the following devices:

the dust remover mainly comprises a bag, wherein a mixture of ash and air is pumped into the bag, the ash and the air are separated through the filtering action of the bag, the air is discharged into the atmosphere from the inside of the bag through an outlet of a negative pressure fan, and the ash falls into an ash warehouse through a gas locking valve under the action of gravity. There are the following disadvantages: firstly, the cloth bag has high water absorption, is easy to scale, is not antistatic, is not flame retardant, has poor ventilation property after long-term work and influences the dust removal effect; secondly, the dust remover produces secondary pollution in the dust removing process; energy loss can be caused when the ash of the dust remover is unreasonable and unscientific; the equipment is easy to age, the maintenance cost is high, the maintenance workload is large, the service life is short, and the occupied area is large; dust is difficult to collect when the pollution source is dispersed, and when certain characteristic dust (such as coal dust) reaches a certain concentration, the dust can explode under the conditions of high temperature, open fire, electric spark, friction and impact; sixthly, the characteristics of dust gas must be considered when the filter material is selected, and the filter material is generally required to have the characteristics of wear resistance, corrosion resistance, low resistance, long service life and the like, so that the manufacturing cost of the filter bag is increased; the nature of the filter material determines that the bag-type dust collector has limitation relative to dust; the treatment effect is poor, although the emission value reaches 50 mg/cubic meter allowed by the state, the treatment indexes of the polluted site can not reach 10 mg/cubic meter specified by the state;

the electrostatic precipitator mainly charges dust particles when dusty gas passes through a high-voltage electrostatic field, the charged dust particles are deposited on the integrated board under the action of the electric field force, and after the dust is deposited to a certain thickness, the dust is vibrated to fall into the dust hopper and is discharged through the dust discharge valve, so that the dust removal purpose is achieved. There are the following disadvantages: firstly, the one-time investment is high, and the consumption of steel is large; secondly, the electric dust collector usually requires higher manufacturing and mounting precision, otherwise, the normal and efficient operation of the electric dust collector cannot be ensured; the electric dust collector occupies a large area due to the low wind speed of the electric field; the electric dust collector has certain requirements on the treated dust, and corresponding measures are needed to ensure the necessary dust removal performance when electric dust removal is adopted for the dust outside the proper range;

thirdly, spraying and dedusting, wherein a water spraying device is additionally arranged on the front section of the belt guide chute and the like, so that the humidity of coal is increased, and the aim of difficult dusting is fulfilled. There are the following disadvantages: water consumption is huge; secondly, the calorific value loss of the coal is large; thirdly, coal slime cleaning causes loss of coal and increases the coal slime treatment cost; fourthly, the treatment effect is poor and can not reach the standard of 10 mg/cubic meter specified by the state;

and fourthly, unpowered dust removal is carried out, the aerodynamic principle is applied, the pressure balance and closed-loop circulation mode are adopted, and the pressure of the dust air of the blanking barrel is reduced to the maximum extent, so that the dust air and the external air pressure tend to be balanced. The material can produce a large amount of negative pressure air current when falling, and the dust is under the guide of negative pressure air current, and the cyclic motion in airtight space strikes the pressure plate, and linear motion becomes curvilinear motion, reduces the potential energy of self, and the dust falls under the effect of gravity, reaches the purpose of removing dust. There are the following disadvantages: firstly, the investment is large; secondly, the dust trapping rate is low; the horizontal pipeline is easy to block, and the trapping rate is influenced; low purification efficiency (usually 40 to 50 percent); large floor area.

Due to the defects, some dust removing equipment of thermal power plants, ports, iron and steel plants, chemical plants, coal mines, coal conveying or material conveying systems are basically in a waste and waste stop state, and the basic targets of dust control cannot be achieved after the dust removing equipment of some power plants, ports, coal mines and the like is replaced for a plurality of times.
