Multi effect evaporation and concentration equipment

Multi effect evaporation and concentration equipment

Multi effect continuous crystallization unit waste water treatment Multi effect continuous crystallization unit According to the material properties, dual effect, triple effect, and quadruple effect continuous crystallization can be used. Our company adopts a multi effect continuous crystallization unit with a heat pump, which integrates advanced design and technology, has good energy-saving effect, and is easy to operate; It is a new type of high-efficiency crystallization energy-saving device. It is widely used in food, chemical, pharmaceutical industries, especially for industrial wastewater treatment and desalination treatment in mining, dyeing, chemical and other industries (various series of inorganic salts such as NaCl, (NH4) 2SO4, CaCl2, CaCO3, including organic salts) Multi effect evaporator unit (dual effect - five effect) The evaporator unit is divided into two series: falling film and internal and external circulation. Overview of Continuous Crystallization Technology

Vacuum crystallization technology is widely used in industries such as fermentation, chemical, and food. Traditional vacuum crystallization technology generally adopts single effect vacuum concentration crystallization, which has disadvantages such as high energy consumption, small processing capacity, and inability to operate continuously.

The continuous crystallizer developed by our company has overcome a series of technical difficulties such as crystal blockage during pipeline transportation, comprehensively corrected the shortcomings of traditional crystallizers, and is in a technological position in China.

The continuous crystallizer produced by our company has been applied to the continuous crystallization of amino acids, ammonium sulfate, and sodium chloride extraction from high salt wastewater. In the process of use, it has been proven that the multi effect continuous crystallizer can greatly reduce energy consumption, with a daily processing capacity of over 1000m3 and many advantages such as easy operation and cleaning, and has received widespread praise from users.

Selection criteria for manufacturing, layout, and operation of evaporators:

In the design of an evaporator, a large number of, sometimes even contradictory, conditional factors must be considered, which will determine the structure and layout of the evaporator, including:

Production capacity and operating parameters, including quantity, concentration, temperature, operating hours, product transformation, automatic control, etc.

Product characteristics, including heat sensitivity, viscosity and fluidity, foam characteristics, scaling and precipitation tendency, boiling behavior, etc.

Selection of manufacturing materials and requirements for surface smoothness.

On site conditions, such as space, climate, energy and product integration, work platform, etc.

Regulations, including safety, accident prevention, noise, environmental protection, etc.

According to the properties of the materials and the requirements of the product, and other process conditions, dual effect, triple effect, and quadruple effect continuous crystallizers can be designed
