Typical performance of water-soluble fertilizer manufacturing industry

The MVR evaporation crystallization system for cellulose wastewater with an hourly processing capacity of 2.5 tons designed by the company for a certain chemical technology limited company has been officially put into operation. The main component of the system feed liquid is sodium chloride, which is a weakly alkaline liquid with a COD content of 90000-160000mg/L and a high salt content. The system adopts the method of evaporation concentration crystallization, and the crystallized sodium chloride is sold as a product to achieve the purpose of waste reuse.

The company has completed the on-site debugging of urea nitrate evaporation and concentration according to the high standards required by the customer. The system operation meets the contract requirements, with a feed rate of 6m3/h, an evaporation rate of 1.5t/h, and an electricity consumption of 84.3KWh/t per ton of water evaporated. Compared with the three effect evaporation system, the energy consumption can be saved by about 40%. Not only did it solve the problem of evaporation and concentration production of urea nitrate solution for customers, but it also effectively demonstrated the company's business capability in designing high difficulty MVR systems.

Service phone number:

The company designed and constructed a nitrate urea liquid MVR evaporation system with an hourly evaporation capacity of 1.5 tons for a certain ecological engineering limited company. Due to the high temperature decomposition and explosion characteristics of urea nitrate feed solution, the system evaporation temperature is designed to be 65 ℃. To ensure the good operation of the low-temperature evaporation environment system, a single-stage high-speed centrifugal steam compressor independently developed and produced by the company is selected, and the shaft seal adopts a containerized carbon ring sealing structure.
