Nitrogen recovery, hydrogen recovery, argon recovery

As an inert gas, nitrogen is widely used as a protective gas for various annealing furnaces. In the production process, this part of the gas does not participate in the reaction and is eventually discharged directly, resulting in a great waste of energy and a certain amount of pollution to the atmosphere.

The nitrogen recovery system launched by Henan Dinak Machinery Equipment Co., Ltd. starts from the process of each industrial furnace, combines the actual working conditions of on-site production, and customizes the nitrogen recovery system for the particularity of each factory's production. This recovery system can reduce the nitrogen consumption by 60%-90%, which can greatly save the gas cost of customers.

The nitrogen recovery system can be applied to industrial furnaces such as continuous withdrawal furnaces, roller hearth furnaces, bell furnaces, pit furnaces, push rod furnaces, and trolley furnaces.

Hydrogen Recovery System

Steel strips, copper strips and stainless steel strips need to be annealed after cold rolling. During the annealing process, hydrogen-containing gas needs to be introduced as a protective gas. This part of the gas is generally discharged or burned directly, resulting in a great waste of resources.

The hydrogen recovery system developed by Henan Dinak Machinery Equipment Co., Ltd. can recover and process this part of the gas, and then pass it into the furnace for recycling, which can save 50%-85% of the protective gas consumption, which can greatly reduce the user gas cost. According to the furnace type, it is divided into two types: bell furnace hydrogen recovery and continuous furnace hydrogen recovery. According to the hydrogen content of the protective gas, it is divided into three types: low hydrogen recovery, high hydrogen recovery and full hydrogen recovery.

Argon Recovery System

Argon is a rare inert gas, widely used in electronics, metallurgy, chemistry, welding, single crystal silicon and other industries. Because of its rarity, it is not easy to obtain. Engineers from the technical department of Henan Dinak Machinery Equipment Co., Ltd. can customize a proprietary argon gas recovery device according to different production processes to reduce the loss of argon gas and save production costs for customers.
