TLH nitrogen hydrogenation purification device

This process is especially suitable for heat treatment, powder metallurgy, copper smelting, steel deep processing, bearing, chemical industry, electronics, glass, metal materials, magnetic materials and other industries.

Process principle:

Process 1: A certain flow of nitrogen and excess hydrogen into the purification unit at the same time, first through the nitrogen and hydrogen automatic mixing device and static mixer uniform mixing, then into the catalytic deoxidizer, under the catalyst, the residual oxygen in nitrogen and hydrogen reaction to form water, chemical reaction formula: 2H2 + O2 = 2H2O, nitrogen after filter dehydration and then into Excess hydrogen is removed from the dehydrogenation unit. If the process permits nitrogen to contain a certain amount of hydrogen, it will not dehydrogenate. Nitrogen is then removed by cooling and drying machine to obtain high purity nitrogen.

Process 2: A certain flow rate of nitrogen and hydrogen into the purification unit at the same time, first through the nitrogen and hydrogen automatic mixing device and static mixer uniform mixing, then into the catalytic deoxidizer, under the catalyst, nitrogen in the residual oxygen and hydrogen reaction to produce water, Nitrogen is then dehydrated through a filter, and the remaining oxygen is absorbed and deoxidized by an oxygen absorption tower (using highly efficient deoxidizing adsorbent). Nitrogen is finally removed by a cold dryer and a suction dryer to obtain dry, high-purity nitrogen. Type TLHA is hydrodeoxygenated and non dehydrogenated.

TLHB is hydrodeoxygenated and dehydrogenated. TLHC is hydrodeoxygenation and reoxygenation. The technology is especially suitable for heat treatment, chemical industry, glass, metal materials and other industries.

Technical indicators:

1.Deoxygenation and dehydrogenation catalysts are highly efficient, durable, long life service and good stability.

2.Deoxidization can be carried out at room temperature without heating, which greatly saves energy consumption.

3.Nitrogenous fertilizer has a wide range of requirements, and nitrogen can be selected within 9899.9%.

4.The hydrogenation purifying unit is equipped with an automatic nitrogen-hydrogen mixing device according to the working conditions. It can automatically calculate and control the amount of hydrogen added according to the inlet amount and purity of nitrogen gas. It is fully automatic controlled. The equipment is sensitive to reaction, has small lag and has high adjusting precision.

5.The contact part of electric and hydrogen by electrical explosion, safe and reliable.

6.The mixing of nitrogen and hydrogen is accomplished in a static mixer with good mixing effect and less hydrogen consumption.

7.Equipped with automatic interlocking and emptying, multiple fault alarm.
