Overview

The second-hand titanium material forced circulation evaporator wastewater evaporator is based on the principle of evaporation concentration crystallization, targeting the characteristics of high salt content and high concentration in chemical organic wastewater Multi effect vacuum evaporation is used to concentrate crystalline organic wastewater. After separating the salt in the concentrated solution, it is recovered through a salt collector. The concentrated solution is then dried and recovered or incinerated. The condensed water after evaporation is generally treated through subsequent biochemical treatment to meet the standards for wastewater discharge. The hourly evaporation rate ranges from 1 to 30 tons, with the concentration ratio of the four effect evaporator reaching 10-15%.

The evaporation capacity of the evaporator ranges from 1 to 30 tons per hour, with the concentration ratio of the four effect evaporator reaching 10-15%. The emulsion wastewater evaporator can greatly reduce or even remove harmful chemicals, heavy metals, etc. contained in the waste liquid. The evaporation rate of the equipment can reach over 90%, and the waste liquid can meet the standards for reuse or discharge of reclaimed water through pre-treatment and post-treatment.

-Overview

Principle of wastewater evaporator: The high salt wastewater evaporator is designed for the characteristics of high salt and high concentration in chemical wastewater. Based on the principle of evaporation, concentration, and crystallization, it adopts multiple effects MVR、 Forced circulation evaporation is used to concentrate crystalline organic wastewater. After separating the salt content in the concentrated solution, it is recovered through a salt collector. The concentrated solution is then dried and recovered or incinerated. The condensed water after evaporation is generally treated through subsequent biochemical treatment, which can achieve the standard of wastewater discharge.

Used titanium forced circulation evaporator2、 Characteristics of high salt wastewater:

High salt wastewater refers to wastewater with a total salt content of at least 1% by mass, mainly from chemical plants and the collection and processing of oil and natural gas This type of wastewater contains various substances, including salt, oil, organic heavy metals, and radioactive substances. The chemical composition is complex and contains a large amount of organic compounds, including organic solvents, organic acids, esters, ketones, phenols, etc., and the salt content is high, such as sodium chloride, ammonium chloride, or multiple mixed salts. It is difficult to directly treat by biochemical methods, and the physical and chemical treatment process is complex and the treatment cost is high. It is a well-known high difficulty wastewater treatment in the wastewater treatment industry. The discharge of high salt wastewater has a huge impact on the environment, so the pollutants in the wastewater must be removed before discharge.

IIIHigh salt wastewater evaporator-Main features

1. Wastewater can be evaporated to meet reuse or discharge standards in one step;

2. The two-step aggregation of wastewater concentration and wastewater salt crystallization is completed in different forms of evaporators, and the salt is separated from the crystallizer in the form of crystals, resulting in good desalination effect;

3. Considering water quality and economic factors, choose evaporation crystallization forms such as multi effect or MVR;

4. Various material equipment can be customized according to user needs;

5. The entire high salt wastewater evaporator is PLC controlled, with flexible system operation and simple operation.

Wastewater treatment has always been an important link in the chemical production process. Chemical wastewater usually contains various harmful substances, and direct discharge not only pollutes the environment but may also violate environmental regulations. Therefore, it is particularly urgent to develop efficient and environmentally friendly wastewater treatment methods. The chemical wastewater evaporator is an excellent equipment that emerged in this context.

The basic principle of a chemical wastewater evaporator is to use evaporation technology to separate the water in the wastewater, thereby concentrating and purifying the useful components or reducing their volume. This process usually includes steps such as heating, evaporation, and condensation. By precisely controlling temperature and pressure conditions, volatile and non-volatile substances in wastewater can be effectively separated.

Compared with traditional biochemical treatment, wastewater evaporators have multiple advantages. Firstly, it can treat high concentration and difficult to degrade organic wastewater, which often poses challenges to biological treatment systems. Secondly, evaporation treatment has high efficiency and can significantly reduce the volume of wastewater in a short period of time, especially for wastewater with high salt content. In addition, valuable chemicals can be recovered during the evaporation process, which not only saves resources but also reduces costs.

Chemical wastewater evaporators require careful control during operation to ensure stable system operation and treatment effectiveness. For example, the design of evaporators should take into account different wastewater characteristics such as corrosiveness, viscosity, and thermal sensitivity. At the same time, to prevent scaling and corrosion, the selection and maintenance of evaporator materials are also crucial. In addition, energy consumption is an important consideration in the evaporation process, so modern evaporators are increasingly adopting energy-saving technologies such as multi effect evaporation and heat pump evaporation.
