氣力輸送系統(tǒng)的設(shè)計(jì)：
Design of pneumatic conveying system:
氣力輸送系統(tǒng)的設(shè)計(jì)方法一般適用于低壓吸引氣力輸送，而對于容積式的高壓壓送式主要是依靠實(shí)踐經(jīng)驗(yàn)進(jìn)行，并結(jié)合在實(shí)際運(yùn)行中的情況加以綜合考慮來進(jìn)行設(shè)計(jì)。
The design method of the pneumatic conveying system is generally applicable to the low-pressure suction pneumatic conveying, while the volumetric high-pressure pressure conveying system is mainly designed by relying on practical experience and considering the actual operation conditions.
低壓吸引式氣力輸送方式多為低壓和短距離輸送，因而可以不考慮空氣的壓縮性，把氣流速度及密度看做不變的進(jìn)行計(jì)算。
The low pressure suction pneumatic conveying mode is mostly low pressure and short distance conveying, so the air compressibility can be ignored and the air velocity and density can be calculated as constant.

對于長距離的高壓壓送式氣力輸送，其輸送壓力高達(dá)幾十萬帕，空氣的可壓縮性則不可忽視。通常吸引式氣力輸送系統(tǒng)的設(shè)計(jì)計(jì)算方法如下：
For long distance high-pressure pneumatic conveying, the conveying pressure is as high as several hundred thousand Pa, and the compressibility of air cannot be ignored. Generally, the design calculation method of the suction pneumatic conveying system is as follows:
1、根據(jù)物料的特性以及阿基米德準(zhǔn)數(shù)Ar來計(jì)算物料的懸浮速度。
1. The suspension velocity of the material is calculated according to the characteristics of the material and the Archimedes number Ar.
2、根據(jù)懸浮速度以及輸送物料的不同情況下的經(jīng)驗(yàn)系數(shù)，確定工作速度。
2. The working speed is determined according to the suspension speed and the empirical coefficient under different conditions of conveying materials.
3、根據(jù)輸送形式所的混合比以及輸送物料的量來決定輸送空氣量和輸送管直徑。
3. The amount of air to be conveyed and the diameter of the conveying pipe are determined according to the recommended mixing ratio of the conveying form and the amount of materials to be conveyed.
4、根據(jù)整個(gè)系統(tǒng)線路布置圖，計(jì)算系統(tǒng)的壓力損失。
4. Calculate the pressure loss of the system according to the circuit layout of the whole system.
5、根據(jù)求得的輸送空氣量和總壓力損失選擇合適的羅茨風(fēng)機(jī)。
5. The appropriate Roots blower shall be selected according to the calculated delivery air volume and total pressure loss.
氣力輸送系統(tǒng)的主要部件有：輸送管道、供料裝置、氣固分離設(shè)備和供氣設(shè)備。
The main components of the pneumatic conveying system are: conveying pipeline, feeding device, gas-solid separation equipment and gas supply equipment.
