Embodiment 1
[0036] A medicinal solution for on-line cleaning of equipment in an air separation workshop, consisting of the following raw materials in percentage by weight: sulfamic acid 10%, urotropine 0.5%, JFC (fatty alcohol polyoxyethylene ether) 0.3%, phosphoric acid tris Butyl ester 0.5%, water 88.7%. The preparation method is to put sulfamic acid, urotropine, JFC and tributyl phosphate in sequence into the cleaning liquid storage tank 15 filled with clear water, and stir evenly to obtain the finished liquid medicine.
[0037] The supporting air separation workshop equipment online cleaning device in this embodiment consists of a shower pipe A (6), a cleaning liquid storage tank 15, a cleaning multi-stage pump 8 with a self-circulation valve 7, and a shower pipe connected in series through the pipeline. Composed of B(9), the device is connected in parallel in the air separation workshop 40000m 3 On the liquid supply pipeline between the liquid storage tank 3 and the liquid ammonia h...
Embodiment 2
[0046] A kind of medicinal solution for on-line cleaning of air separation plant equipment, consisting of the following material raw materials in percentage by weight, citric acid 30%, oleoyl imidazoline 0.3%, tributyl phosphate 0.2%, JFC (fatty alcohol polyoxyethylene ether ) 0.25%, water 69.25%.
[0047] The matching online cleaning device and online cleaning method of this embodiment are the same as those in Embodiment 1.
Embodiment 3
[0049] A chemical solution for on-line cleaning of air separation plant equipment, consisting of the following raw materials in weight percent, 50% glycolic acid, 0.4% LAN-826, poly(dimethylsiloxane-3-hydroxypropylmethylsilane Oxyalkylene) polyoxyethylene ether 0.3%, fast T (sodium succinate sulfonate) 0.25%, water 49.05%.

Abstract
The invention relates to liquid medicine for online cleaning of air separation workshop appliances and an application method of the liquid medicine. The liquid medicine for online cleaning of the air separation workshop appliances comprises organic acid, corrosion inhibitors, penetrant, antifoaming agents and water. A method for online cleaning of the air separation workshop appliances through the liquid medicine comprises the technological steps that a cleaning system of a cleaning liquid storage tank and a cleaning multi-stage pump is established, water scale is cleaned away, and the system is recovered. The liquid medicine for online cleaning of the air separation workshop appliances is stable in chemical property, good in slow-release effect and high in scale dissolving capacity. The method for online cleaning of the air separation workshop appliances through the liquid medicine is simple in technology and low in cost. The corrosion hazard cannot be caused to the air separation workshop appliances including an air cooling tower and accessory devices of the air cooling tower, shutdown of an air separation workshop is not required, and product manufacturing is not affected.
Description
technical field [0001] The invention belongs to the technical field of chemical cleaning, and relates to a medicinal solution for on-line cleaning of equipment in an air separation workshop and a using method thereof. Background technique [0002] In the daily production of air separation plant equipment (liquid ammonia heat exchanger, spray distributor, air cooling tower, etc.), due to the continuous circulation and concentration of water during use, the mineral content in the water continues to increase, which causes equipment scaling. Once the liquid ammonia heat exchanger is scaled, the cooling effect of the liquid ammonia heat exchanger will be greatly reduced, and the low-temperature water flow rate of the liquid ammonia heat exchanger will be reduced; once the spray distributor is scaled, it will cause the spray distributor to drift, The heat exchange efficiency between hot air and low-temperature water is reduced; and once the outlet air temperature of the air-coolin...
