After checking that the condition of the hot water tower is normal, the oil-filled layer in the oil separator in front of the saturated tower is blown over, forming a partial empty tower, which does not have any separation effect. This is mainly because the system oil is lost after the filler is blown over. Separation is lost, so the oil mist carried by the gas directly enters the saturation tower compressor without a cooling separator, in order to reduce the conversion steam consumption. The liquid oil is formed by hot water spray washing, and the dust and solid particles in the gas and the hot water adhere to the filler, causing the filler to block the cold, which is the main cause of the liquid.
After the chemically cleaned filler is cleaned and the attachment is removed, the filler surface is as bright as new and can continue to be used. After discussion, it was decided to treat it by the alkaline washing method.
3.1 Cleaning process: Lift 50,0 as the cleaning pump, between the pump outlet pipe and the water heater desaturation tower line, connect with 2 pipes of 0159, and add between the water heater and the saturated tower, 1 as the cleaning inlet. Drain the tank at the water seal tube at the bottom of the saturated bottom. Complete the flow, the road. Remove the liquid trap in the saturation tower. And a lotus fan type nozzle, so that the lye or hot water with a relatively high flow rate is directly flushed onto the filler.
5. Raw water plus process pipeline. 6. Raw water seal pipeline. 7. Blind plate water rinse. The purpose is to remove the oxides and other loose and dirt that are deposited in the system. The leakage condition is checked at the temporary take-over in the simulated cleaning state.
Flush with a large flow rate and control the inlet and outlet water balance.
2. Degreasing and desulfurization. The purpose is to remove oil sulphur from the system. Sulfur can be dissolved to form the corresponding polysulfide.
Fill the system with fresh water, circulate and heat. Gradually add the degreasing and desulfurizing agent, mix it evenly and circulate. Initially, the alkalinity is lower than that of "kui", and the basic acid content of the system is basically balanced. The alkali powder of the top of the column is observed to be the original color of the stainless steel.
Sodium phosphate, sodium hydroxide, sodium sulfide, surfactant, active agent, penetrant. Use process conditions: 2. Alkalinity, oil content, and temperature are tested every 30 times.
Temperature, time h3 water rinse. The goal is to remove the degreased residue from the system.
After the degreasing liquid is drained, it is rinsed with water, and the flushing flow rate is 1.0, 1.2. When the influent 1 water 1 turbidity is basically balanced, the flushing can be ended. The process takes about 81 times and eventually reaches 78.
Quality acceptance corrosion rate. After cleaning, the stainless steel filler surface should be free from pitting and local corrosion. The maximum corrosion rate of the coupon is much less than the chemical cleaning quality standard for industrial equipment, 238,792.
Net rate. The stainless steel surface is clean, showing a uniform color, and the removal rate is above 85.
Conclusion: Modify the operation rules village. Increase the frequency of oil separator discharge to prevent excessive accumulation of oil into the saturation tower, and strictly control the total solids content of circulating hot water.
Chemical cleaning of the saturated column packing is possible and very successful.
The system piping is utilized during cleaning, which saves a lot of manpower and material resources.
