I. Introduction of pneumatic conveying equipment :
Pneumatic conveying equipment uses air jet to make the ash particles drive the ash to the ash warehouse. The pneumatic conveying equipment mainly consists of four parts: nozzle, cylindrical pump body, nozzle adjustment device, bottom vaporization device, and pneumatic conveying equipment. The energy of the time comes from two parts: one is the kinetic energy of the fan, and the other is the potential energy of the material column. LFB-1 series pneumatic conveying equipment is a new type of low-pressure pneumatic conveying equipment developed by our factory in cooperation with the Building Materials Institute based on the introduction of advanced foreign technology and the various problems existing in different types of domestic pneumatic conveying equipment. The conveyance of all kinds of powdery materials for grey cement uniform and inverted storage is highly efficient and low consumption. It is completely closed and pollution-free. There is almost no maintenance. Roots blower compressed air can be selected.
Two: advantages of pneumatic conveying equipment
1. The equipment investment is small. One pneumatic conveying equipment can replace two warehouse pumps, which reduces the equipment investment.
2. The air pressure of pneumatic conveying equipment is 0.04Mpa-0.1Mpa, which reduces the air supply pressure, saves air consumption, and reduces the motor power.
3. Reduced maintenance costs. After the system is installed, commissioned and put into operation once, it basically needs no operation, and there is almost no maintenance. The maintenance workers only need to check regularly.
4. Low pressure conveying, the equipment has good sealing performance, reliable operation, no pipe blocking phenomenon, and the environment is improved
Since the equipment was put on the market, it has been proved by many uses that the pump has a smaller volume and lower air pressure (0.2--1 atm.). It can be equipped with a fan), easy to arrange, no dust, and meet the requirements of environmental protection. It is widely used in electric power, building materials, chemical industry and other fields. It is an ideal equipment for lifting and conveying powdery materials such as cement, raw meal and fly ash within an equivalent distance of 680m and a height of 50m. The main feature of this pneumatic conveying equipment is its long service life. Reliable operation, almost no maintenance and wear parts.
Three: working principle
Pneumatic conveying equipment uses air jet to make the ash particles drive the ash to the ash warehouse. The pneumatic conveying equipment mainly consists of four parts: nozzle, cylindrical pump body, nozzle adjustment device, bottom vaporization device, and pneumatic conveying equipment. The energy of the time comes from two parts: one is the kinetic energy of the fan, and the other is the potential energy of the material column. The material column is high, the potential energy is large, the pressure is large, and the conveying capacity is correspondingly large, otherwise it is small.
Pneumatic conveying equipment maintains a certain level of material during normal operation. When the amount of material under electrical dust collection increases in a short time and the pneumatic conveying equipment is still working normally, the level of the material naturally rises. As the material level increases, the material pressure increases. The increase of large potential energy will increase the corresponding amount of output until the system automatically balances. When the amount of material under electric dust collection is reduced in a short time and the pneumatic conveying equipment is still working normally, the material level will naturally decrease. As the material level decreases, the potential energy decreases. The corresponding delivery volume is small until the system automatically balances.
Four: Operating conditions
1: The necessary condition for the normal operation of pneumatic conveying equipment is that there must be a certain material seal height. The pressure of the silo level should be greater than the positive pressure when working in the pneumatic conveying equipment. The positive and negative pressures are separated by the material level pressure. Press to send the material away, so a certain level of material height is necessary.
2: The dust collector must be installed on the receiving warehouse. The exhaust air volume of the dust collector must be greater than the inlet air volume of the ash conveying fan. Balanced, the pipeline resistance is large, and the inlet air blows back from the pneumatic conveying equipment to the part above the silo, so that the pneumatic conveying equipment cannot work normally.
Five: Selection principles and applicable conditions
1. Selection principle
Low-pressure pneumatic conveying equipment is selected as the core equipment to form a pneumatic conveying system. First, the user should provide: the system's required conveying volume, conveying distance, or physical and chemical parameters of the material, high temperature and normal working temperature; Provide basic parameters such as dust hopper layout and ash distribution. Then the technical personnel of our factory first determine the basic transportation plan, such as the required gas volume, how to group, the continuous pump model, the configuration of the inlet and conveying pipes, and the configuration of the deduster at the top of the warehouse.
2. Applicable conditions
Low-pressure pneumatic conveying equipment Due to the use of low-pressure conveying, the pneumatic conveying equipment has a limited range of use. It can be used normally and safely only under the following conditions and achieves the expected effect.
Conveying distance ≯500m (equivalent distance).
Material bulk density: 2.0t / m3 (powder).
There are no more than 4 large pumps (that is, 4 ash pipes in total).
The material's high instantaneous temperature is ℃ 250 ℃.

Structure of pneumatic conveying equipment
Pneumatic conveying equipment is mainly composed of material sealing warehouse, feed regulating duct, fluidized gas box, actuator, spray head, nozzle and so on.
Pneumatic conveying equipment is a realistic approach to the development model and an inevitable choice for achieving a win-win situation for economic development and resource environmental protection. Under the guidance of the concept of sustainable development, pneumatic conveying equipment is a type of positive pressure conveying system in which pneumatic conveyance commonly used in industry is reduced as much as possible through technological innovation, institutional innovation and industrial transformation. , So there is almost no pollution to the environment. Consumption of high-carbon energy such as coal and petroleum, reducing greenhouse gas emissions, and achieving a win-win situation of economic and social development and ecological environmental protection is a form of economic development.
We have only combined the actual situation to make the pneumatic conveying equipment play a great role. The pneumatic conveying equipment has played a great role in protecting the environment. Recently, we have made new breakthroughs.
