The pipeline of pneumatic conveying equipment is seriously worn, resulting in ash everywhere, which not only affects the production, but also pollutes the environment. How to solve the problem of pipeline leakage?

1降低吹灰時的風壓，減少磨損，節(jié)約能源，但這種方法可以延長輸灰管道的使用壽命，但不能從根本上解決磨損問題。

1. Reduce the wind pressure during soot blowing, reduce wear and save energy, but this method can prolong the service life of ash conveying pipeline, but it can not fundamentally solve the wear problem.

2管道四周做方盒、灌水泥或加澆注料、耐磨材料的成本不高，這種方法與修補沒有區(qū)別，只能小范圍使用，不能批量解決問題。

2. The cost of making square boxes, pouring cement or adding castables and wear-resistant materials around the pipeline is not high. This method is no different from repair. It can only be used in a small range and can not solve the problem in batch.

3將耐磨陶瓷粘貼在管道中，以Al2O3為主要原料，以稀有氧化物金屬為溶劑，經(jīng)1700℃煅燒的特種剛玉陶瓷制成耐磨陶瓷片。

3 the wear-resistant ceramics are pasted in the pipeline, and the wear-resistant ceramic sheet is made of special corundum ceramics calcined at 1700 ℃ with Al2O3 as the main raw material and rare oxide metal as the solvent.

氣力輸送設備陶瓷內(nèi)襯氣力輸送設備具有以下優(yōu)點：

Pneumatic conveying equipment ceramic lined pneumatic conveying equipment has the following advantages:

1硬度高，陶瓷硬度高，莫氏硬度在9度以上，僅次于金剛石硬度。

1 high hardness, high ceramic hardness, Mohs hardness above 9 degrees, second only to diamond hardness.

2耐磨性好，耐磨性是錳鋼的30倍，高鉻鑄鐵的20倍；

2. Good wear resistance, which is 30 times that of manganese steel and 20 times that of high chromium cast iron;

3陶瓷的密度只有鋼的一半，大大減輕了鋼管的重量。

The density of ceramic is only half that of steel, which greatly reduces the weight of steel pipe.

陶瓷內(nèi)襯管的使用壽命是普通耐磨管的10倍以上，避免了購買新管道，節(jié)約了采購成本，延長了舊管道的使用壽命，減少了管道的維護，優(yōu)化了人力資源配置，也可采用雙金屬復合管，但是成本更高更重。如果耐磨陶瓷管彎頭半年才能磨損，這是正常情況下的設計問題，需要檢查整條管道的實際直徑是否與設計相符彎頭半徑按工藝設計加大彎頭的轉(zhuǎn)彎半徑可以在一定程度上減少磨損。

The service life of ceramic lining pipe is more than 10 times that of ordinary wear-resistant pipe, which avoids the purchase of new pipes, saves the procurement cost, prolongs the service life of old pipes, reduces the maintenance of pipes, optimizes the allocation of human resources, and can also use bimetallic composite pipes, but the cost is higher and heavier. If the wear-resistant ceramic pipe elbow can only wear for half a year, this is a design problem under normal circumstances. It is necessary to check whether the actual diameter of the whole pipe is consistent with the design. Increasing the elbow radius according to the process design can reduce the wear to a certain extent.
