The distiller is an all-glass structure. Distillers can be removed. Steam cleaning is set after each sample is distilled. During the empty steam cleaning process, the cooling water in the condenser tube can be automatically discharged, the temperature in the tube can be increased, and high-temperature steam can be fully used to drive away trace residual ammonia, thereby effectively overcoming 15N cross-contamination. The center of the distillation system is the rotating body, which is already the core part of the automatic Kjeldahl nitrogen analyzer. Both ends are a pair of mechanical logic components, and they have a vent valve, a base valve, a steam valve, and a cooling water valve. This logic element is designed according to the analysis program and performs the respective logic functions in order.
The Huale-distillation unit rotates for one week, including seven steps of adding alkali, alkali cleaning, cooling water, distilling, ammonia absorption, unloading cooling water and steam cleaning. Each step is arranged at a specific location. Therefore, the six-unit distiller only requires a steam system, a set of alkali, alkali cleaning and steam cleaning devices, simplifying the structure. The electronic control system is the control center of the automatic Kjeldahl nitrogen analyzer. It controls the mechanical logic unit through the integrated block logic circuit to complete the sample distillation process.
The dynamics study in the automatic Kjeldahl nitrogen analyzer has a great effect on the design of the instrument and the improvement of the precision on the structure. A sudden change in the ammonia distillation shows that the amount of steam is substantially more than 90% in the first 60-120 seconds, and the others are delayed to within 500-700 seconds. At the early and late stages of the measurement process, the reduction of steam condensate will occur. The test results show that the automatic Kjeldahl nitrogen analyzer is unstable under the condition of high ammonia concentration, and the absorption change range is relatively large, so the control The early absorption of ammonia concentration is the key.
Outdoor Container all-in-one PSA Nitrogen Plant is the compact Nitrogen Generator designed for customers who need all-in-one solution. For some customers, their site area is limited, and they prefer one Container Nitrogen Generator every part inculded. Some cusotmers need the nitrogen generator have low noise, rain proof, this container type nitrogen plant is the ideal solution.
Air Compressor suction air from atmosphere,then the compressed air enters one air treatment part to get rid of dust,water, dust,etc, achieving clean and dry compressed air. This air treatment part mainly consists of three filters, one Refrigerant Dryer and one activated carbon oil remover. After treatment, the compressed air enters one air tank to make air stable. Then the compressed air enters PSA nitrogen/oxygen separator. After passing through this nitrogen/oxygen separator part, nitrogen is collected. The produced nitrogen enters one nitrogen buffer tank. At the outlet of nitrogen buffer tank, stable and qualified nitrogen is sent to using point.
