What ventilation measures should be taken in the production of oxalic acid

Date of release:2019-03-14 Author: Click:

1. The production of oxalic acid should strictly abide by the operating rules. It should be fully ventilated through closed operation.

2. Use explosion-proof ventilation system and equipment. Prevent steam from leaking into the air of the workplace. When filling, flow rate should be controlled and grounding device should be provided to prevent electrostatic accumulation. Oxalic acid avoids contact with oxidants, alkali metals, acids and amines.

3. Equipped with the corresponding variety and quantity of fire fighting equipment and leak emergency treatment equipment. Empty containers may retain harmful substances. Store in a dry, cool and well ventilated warehouse. Keep away from fire and heat sources. Oxalic acid packaging sealed, do not be damp. It should be stored separately from inflammables and acids.

Note: When producing oxalic acid, keep the ventilation in the workshop at any time. Operators should pay more attention to observe the production situation. After production, clean up the residues on the table in time.

What are the heating methods for the production of refined oxalic acid?

1. Refining oxalic acid in the production process, to be heated, first evaporation of liquid alkali, concentration to the corresponding concentration, and then follow-up processing.

2. The molten salt is then transported by a molten salt pump to circulate the whole molten salt system. The high temperature flue gas from the molten salt furnace enters the steam generator, then passes through the air preheater to cool down and enters the water film dust collector.

3. The refined oxalic acid molten salt heating unit is a coal-fueled molten salt heating system, which is used to control the temperature of molten salt reaching the concentrator to meet the process requirements of the high concentration unit.

What is the water absorption of industrial oxalic acid?

1. Industrial oxalic acid has strong corrosiveness, water absorption and deliquescence. It can be used as a desiccant. However, acid gas can not be dried because it can react with acid gas. It is easy to be deliquescent and liquefied in air, soluble in water and emits a lot of heat at the same time.

2. Industrial oxalic acid corrodes some metallic substances and does not corrode plastics. Only a few minutes in the air will absorb water, so when cleaning the dirt on metal equipment, dilute it first.
