高压发送罐输送系统（密相）
一种正压气力输送系统。采用压缩空气作为输送动力。 采用一个压力容器作为加料装置。适合于粉料，特别是流动性不好的粉料。
高压发送罐输送系统又称仓泵输送系统，它是正压气力输送系统中的一种，通常以密相形式进行输送。
相对于传统的正压输送系统，高压发送罐输送系统采用发送罐而不是旋转阀或文丘里管作为物料加入装置。此外，发送
罐输送系统的输送压力相对较高.固气比相对较高。应用于输送粉料、粒料，尤其适用于流动性不好的物料长距离、高效率的输送。
特点
▲高固气比带来高的输送效率
▲采用离压气体进行输送，耗气量少，运行成本低
▲输送距离从几米到几公里都可以
▲较低的气流速度降低了管道的磨损，也可避免脆性颗粒与管壁激烈撞击而产生破碎。
▲系统中没有运动部件.故障少.维护费用低
▲对于化学性质不稳定的物料，可以用特定的气体进行输送
▲密闭的输送管线，不受气候和周围条件的影响，避免物料妥潮、污损、混入异物
▲多个发送罐可以组合使用，满足用户不同的输送要求
High pressure transmission tank conveying system (dense phase)
A positive pressure pneumatic conveying system. Using compressed air as the conveying power. Use a pressure vessel as the feeding device. Suitable for powders, especially powders with poor flowability.
The high-pressure transmission tank conveying system, also known as the bin pump conveying system, is a type of positive pressure pneumatic conveying system that is usually transported in dense phase.
Compared to traditional positive pressure conveying systems, high-pressure sending tank conveying systems use sending tanks instead of rotary valves or Venturi tubes as material addition devices. In addition, sending
The conveying pressure of the tank conveying system is relatively high The solid to gas ratio is relatively high. Applied to conveying powders and granules, especially suitable for long-distance and high-efficiency transportation of materials with poor fluidity.
characteristic
▲ High solid to gas ratio brings high transportation efficiency
▲ Using high-pressure gas for transportation, with low gas consumption and low operating costs
The conveying distance can range from a few meters to several kilometers
The lower airflow velocity reduces the wear of the pipeline and can also prevent brittle particles from violently colliding with the pipe wall and causing breakage.
There are no moving parts in the system Less faults Low maintenance costs
For materials with unstable chemical properties, specific gases can be used for transportation
▲ A sealed conveying pipeline that is not affected by climate and surrounding conditions, avoiding material moisture, contamination, and foreign matter mixing
Multiple sending tanks can be combined to meet different conveying requirements of users
