Filter in front of steam pressure reducing valve First check whether the steam has had heat,How much heat is there?Because the steam with high overheating will cause the filter screen to deform when passing through the filter screen;However, steam without overheating or low overheating may also cause some steam to liquidate due to throttling after flowing through the filter screen,Create an image of water impact.Check if there is a blockage in the drain line at runtime (or before,Or whether the heating pipe before the pressure reducing valve has reached the goal,Whether the drainage has been completed.The drain device before the decompression system should be normally opened.In addition,There may be problems with your operation.First open the pipeline after the pressure reducing valve,Then open the pipeline before the pressure reducing valve,If the drainage is not smooth or not enough,It may also cause damage to the filter screen.The water impact of the steam is actually when the steam partially condenses
ClO2 is a yellow-green gas with irritating smell at normal temperature. its melting point is-59 ℃ and its boiling point is 11.0 ℃, which is easy to dissolve in water. it is slightly wet in industry. (1) make full contact with the reactants,Speed up the reaction rate and stir at reaction time;The instrument measuring the temperature is a thermometer,Therefore, the answer is: increase the contact area of reactants,Speed up the reaction rate;Thermometer;(2) the melting point of chlorine dioxide is low,To collect chlorine dioxide,Should be carried out at a lower temperature,So ice water bath should be used,Fully condensed,Reduce volatility;(3) the production of solute from solution,Generally, the method of evaporation, Crystal, filtration, washing and drying is adopted,?O,Therefore, the answer is: 2 Hot filtration;3 with 38 ℃ ~ Washing hot water at 60 ℃;4 Dry below 60 ℃;(4) 1 preparation of 100 c mol?-When the standard solution,100 vo
Wastewater treatment, air flotation and sand filtration still have a lot of fine slag flowing out, how to filter it out? Deal with some suspended matter by means of coagulation and fine sand filtration;The current problem of air floatation filter effect is to find the original gas in the original treatment process--
