The molybdenum industry has seriously analyzed and summarized the production and operation of sodium nitrite workshop in 1-9 mon

Recently, the molybdenum industry organization held the production and business meeting of the month of 1-9, carefully summarized and analyzed the production situation of the sodium subsodium workshop, focused on the existing problems, the methods to solve the problems clearly and the direction of the next key regulation.

The 1. alkali consumption exceeds the standard. In the next step of regulation and control, we should focus on the control of dripping and dripping, focusing on eliminating waste generation and digesting existing waste.

2. the control of natural gas consumption in the sodium subsodium two workshop. It is necessary to make full use of the roasting heat transfer, rationally match the ratio of calcining heat transfer and sodium subsodium gas heating, and remould the combustion chamber and heat supply pipe, and make full use of heat transfer.

3. the sodium subsodium two workshop was completely neutralized with soda. At present, soda ash two workshop can not be used in a large amount of soda, the key is neutralization link. The next step is to remould the alkali slots, neutralization grooves and pipelines, and set up the corresponding facilities so that the neutralization of soda can be used in an all-round way.

The improvement and stability of the 4. grade. In order to solve the problem of low grade in 7 and August, it is pertinent to solve the influence of production equipment, technology and operation process on the grade, strictly control the content of free alkali and sodium sulfate, and ensure that the grade of continuous operation reaches more than 85%.

5. sodium silicate two workshop absorption tower and pipeline problems. Focus on effective regulation and control, as a factor affecting normal operation, do monitoring in operation, check the system situation every week, and do well in production tracking.

6. the west line absorption tower of the sodium subsodium two workshop was reformed. In view of the fact that the corrosion of the original ceramic tiles and the cinder blocking the nozzle can not be absorbed normally, it is planned to use 40 days to complete the anticorrosion of Po from November.

7. sodium subsodium one workshop repair. It mainly completes chimney repair, equipment repair, system inspection and key inspection of environmental protection facilities.
