Relying on the "three small and one training" activity platform, Shaanxi Jiao Chemical Company has recently implemented a series of small technical reforms with strong operability and significant effects in reducing energy consumption, solving major production problems
.
Modification of the cooling system of the ammonium sulfide distillation tower to lower the water temperature
.
Recently, with the arrival of the high temperature season, the efficiency of the waste water heat exchanger of the ammonium sulfide ammonia distillation tower in the second workshop of Shaanxi Jiao Co.
The cooling medium of the waste water heat exchanger of the ammonium sulfate distillation ammonia tower is a section of circulating water.
When the water temperature reaches 27°C~32°C, even if the water valve of the ammonia water heat exchanger is adjusted to the maximum, the temperature of the waste water outlet is above 40°C, which is difficult.
Satisfying the biochemical inlet water temperature index affects the biochemical wastewater treatment effect
.
After multiple demonstrations in this workshop, the cooling water of the wastewater heat exchanger of the ammonium sulfate distillation ammonia tower was transformed from the first-stage circulating water to the second-stage circulating water for heat exchange
.
As the chilled water enters the ammonia heat exchanger, the temperature of the ammonia-distilled wastewater gradually decreases from 43°C to 38°C and 33°C.
On-line descaling ESD transformation of circulating water makes the water quality clearer
.
Since the circulating water system of the alcohol-ammonia workshop of Shaanjiao Huangling Coal Chemical Company was put into operation, the water quality has been unsatisfactory due to water source constraints, resulting in a reduction in the heat exchange efficiency of the condenser, resulting in many problems such as electricity consumption, increased heat consumption, and equipment damage in advance.
After several communications with Shangyuan Water Company, the technical staff of the alcohol ammonia workshop decided to improve the water quality by transforming the ESD system for the on-line descaling of circulating water
.
The system is composed of two systems: automatic dosing and online automatic dredging.
"Since the circulating water online descaling ESD system was put into operation, on the one hand, the automatic dosing system can continuously and constantly dosing chemicals for 24 hours, reducing the calcium and magnesium ions in the circulating water, and preventing the corrosion, scaling and sticking of the coolers of each compressor unit.
