Sodium formate drying equipment

Abstract

The invention relates to the field of chemical engineering production equipment, in particular to sodium formate drying equipment. The drying equipment comprises a charging auger; a discharge end of the charging auger is connected with a flash evaporation drying machine; a pulse airflow dryer is mounted at a discharge end of the flash evaporation drying machine; a cyclone dust remover is mounted at one end of the pulse airflow dryer; a dust removing part is mounted at one end of the cyclone dust remover; a storage pool is arranged at the other end of the cyclone dust remover; the dust removing part comprises a system induced draft fan and a cloth bag dust remover; a discharge end of the cloth bag dust remover communicates with the storage pool; dust removing bags are arranged in a box body; a dust hopper is mounted at the lower part of the box body; a separation plate is mounted in the box body; each dust removing bag communicates with the dust hopper through a switch valve; a steam heat exchanger is mounted at an intake end of the flash evaporation drying machine; and a system air blower is mounted at the end part of the steam heat exchanger. The drying equipment realizes drying of sodium formate, prevents influence on sodium formate by other substances in air, and reduces atmospheric pollution.

Description

technical field [0001] The invention relates to the field of chemical production equipment, in particular to a sodium formate drying equipment. Background technique [0002] Sodium formate, also known as sodium formate, contains two crystal waters in the crystal, so it is also known as sodium formate dihydrate, sodium formate dihydrate, sodium formate dihydrate; sodium formate is the simplest organic carboxylate, white crystal or powder, Slight formic acid smell. Slightly deliquescent and hygroscopic. Soluble in about 1.3 parts of water and glycerin, slightly soluble in ethanol and octanol, insoluble in ether. Its aqueous solution is alkaline. Sodium formate decomposes into hydrogen gas and sodium oxalate when heated, followed by sodium carbonate. Sodium formate is mainly used in the production of hydrosulfite, oxalic acid and formic acid. In the leather industry, it is used as a camouflage acid in the chrome tanning process, a catalyst and a stable synthetic agent, and...

AI Technical Summary

Problems solved by technology

[0003] The sodium formate produced is easy to absorb moisture in the air due to its own deliquescence and hygroscopicity, thereby affecting the quality of the product. However, the existing drying equipment is easy to cause the decomposition of sodium formate because of the high temperature, and the drying effect is not good. , and the dried gas will have some other impurities causing environmental pollution
