近年來，國內(nèi)管道清洗技術(shù)發(fā)展迅速，但目前常用的高壓清洗、化學(xué)清洗等技術(shù)仍存在缺陷，高壓管道清洗技術(shù)有哪些需要改進的地方?詳細(xì)介紹了管道高壓清洗的弊端。
in recent years, the domestic pipeline cleaning technology has developed rapidly, but the commonly used high-pressure cleaning, chemical cleaning and other technologies still have defects. what needs to be improved in high-pressure pipeline cleaning technology? the disadvantages of high-pressure pipeline cleaning are introduced in detail.
脫硫酸氣管道堵塞后，采用高壓水槍沖洗法。這個方法是嚴(yán)格的。直管間距小于10m, u型管兩端切斷，法蘭連接有利于檢測沖洗效果。
after the pipeline of desulfurized acid gas is blocked, the high-pressure water gun flushing method is adopted. this method is strict. the distance between straight pipes is less than 10 m, both ends of u-shaped pipes are cut off, and flange connection is conducive to the detection of flushing effect.

what needs to be improved in the current pipeline high-pressure cleaning technology?
這項法律存在一些問題:
there are some problems with this law:
(1)沖洗前，應(yīng)通過堵塞盲板的方法，切斷沖洗段管線和運行管線。
(1) before flushing, the pipeline in flushing section and operation pipeline shall be cut off by blocking the blind plate.
(2)根據(jù)沖洗規(guī)定，需要將管道切割成段，然后焊接法蘭。
(2) according to the flushing regulations, it is necessary to cut the pipe into sections and then weld the flange.

(3)管路四周留有dn200的水平空間，有利于沖洗時避免管路在沖洗段的安裝位置，允許沖洗高壓水槍進入管路進行高壓水清洗。
(3) dn200 horizontal space is reserved around the pipeline, which is conducive to avoiding the installation position of the pipeline in the flushing section during flushing, and allowing the flushing high-pressure water gun to enter the pipeline for high-pressure water cleaning.
由于維修時間的限制，水槍的壓力不能完全破壞硬塊，導(dǎo)致沖洗不徹底，導(dǎo)致沖洗效果不佳。
due to the limitation of maintenance time, the pressure of water gun can not completely destroy the hard block, resulting in incomplete flushing and poor flushing effect.
沖洗后，在酸性氣體管道連接過程中，存在法蘭連接不緊、酸性氣體泄漏的隱患。在洗滌過程中，雜質(zhì)殘渣和污水容易造成環(huán)境污染。
after flushing, there are hidden dangers of loose flange connection and acid gas leakage in the process of acid gas pipeline connection. in the washing process, impurity residue and sewage are easy to cause environmental pollution.
