For different parts of the wastewater evaporator equipment, different requirements should be followed during installation. For example, for the evaporation part, that is, when the heating chamber is installed, the heating chamber and the separation chamber are usually weighed together one by one, and lightly lifted and lightly placed, and the verticality is according to the requirements on the equipment diagram. Generally, the equipment is placed horizontally and sleepers are placed before installation. During the lifting process, gently lift and lower, to avoid excessive vibration of the tube bundle to damage the nozzle and surface of the equipment.

When the concentration of the product is about 50%, only the MVR evaporator can complete it. When the required concentration is 60%, a flash evaporation device is required.

Metal corrosion: MVR evaporators are generally made of titanium, stainless steel 2205, 316L, 304 and other metal materials. Metal corrosion cannot be avoided. Metal corrosion refers to the damage of metal materials by the surrounding medium. It is the most common form of corrosion. Metal corrosion is divided into chemical corrosion and electrochemical corrosion.

FC (forced circulation) crystallizer consists of crystallization chamber, circulation tube, circulation pump, heat exchanger (optional) and so on.

Filters are classified according to filter media: air filters, liquid filters, network filters, light filters.

Characteristics of multi-effect mode evaporator; relatively compact structure, reasonable layout, small footprint, easy to install; high production efficiency is the characteristic of multi-effect mode evaporator, its evaporation capacity is huge; multi-effect falling film The energy saving effect of the type evaporator is very significant, and the energy consumption is about one third of that of the general mode evaporator. QMA is less than or equal to 0.44, and QB / Q is less than or equal to 7.99, where Q refers to the evaporation of fresh water, QA refers to the consumption of steam, and QB refers to the consumption of cooling water.

The forced circulation evaporation crystallizer material liquid is quickly heated by the heater through the forced circulation pump, and the top comes out directly and enters the evaporation separator tangentially. The vapor-liquid separation effect is good.

For the evaporation of high-salt industrial wastewater, crystals will precipitate as the solvent evaporates to form a saturated solution. According to the change of the solubility of different materials with temperature, it is divided into two types: evaporation crystallization and cooling crystallization. Crystals are deposited on the heating surface and hinder heat transfer. Generally, external boiling evaporators are used, such as forced circulation, long tube with special boiling zone and multi-stage flash evaporation. On the one hand, the occurrence of boiling in the heating zone is planned, and on the other hand, the circulation flow rate is increased to wash away the deposited salt scale. It is generally believed that the rising film cannot be used for the evaporation of a saturated solution, and the falling film can also be used for a solution with a certain amount of crystal precipitation when the evaporation amount is large. In the treatment of high-salt industrial wastewater, evaporation and crystallization processes are usually combined, so that the salt analysis is separated from the system in the form of products, and the remaining solution can reach the discharge standard.

Evaporator process, different processes used in multi-effect evaporators will also affect the price. The evaporator process is affected by the solution solubility, melting point, boiling point and other data, which is related to the use of vacuum, atmospheric pressure, negative pressure, falling film evaporation Choice of process, and forced circulation process.

In the process of using the MVR evaporator, it will inevitably need to be debugged or some failures handled, which requires the merchant to provide after-sales service. High-quality after-sales service is also an important way to increase customer trust.

Main features of multi-effect falling film evaporator Spray feeding at the top of the evaporator ensures that the liquid material is evenly distributed in the evaporator film tube, forming a film shape, which greatly increases the heat transfer coefficient and increases the evaporation rate, which can prevent "dry wall" phenomenon.
