Triple-effect evaporator

Three-effect evaporator

Product Overview

The triple-effect evaporator employs simultaneous triple-effect evaporation, with the secondary steam undergoing repeated action, thereby saving both boiler investment and energy consumption. Energy consumption is reduced by 70% compared to single-effect concentrators, allowing users to recoup the full investment in the concentrator within less than a year. The triple-effect evaporator utilizes external heating, natural circulation, and vacuum evaporation methods, featuring fast evaporation rates, high concentration ratios up to 1.2-1.3. It is suitable for concentrating solutions in traditional Chinese medicine, Western medicine, starch, monosodium glutamate, dairy products, chemicals, and more, particularly for the low-temperature vacuum concentration of heat-sensitive materials. Users can select the appropriate series of concentrators based on their specific technical requirements.

Product Features

This equipment operates on a tube bundle-type external heating circulation principle, which results in short heating time for materials, rapid evaporation, high concentration ratio, and effective preservation of the original efficacy of the material.

High energy-saving effect, saving about 70% of evaporation compared to single-effect evaporators. Material is evaporated and concentrated in a closed system, ensuring a clean and comfortable environment; the unique defoaming device of this system prevents material leakage.

All parts in contact with materials are made of imported stainless steel and are polished for excellent corrosion resistance, easy cleaning, and compliance with food hygiene regulations. Available with a microcomputer control system for simple operation and stable performance.

Application Scope

Wastewaters that are unsuitable for treatment by biological, chemical, or membrane processes, such as high-salt wastewater, electroplating wastewater, dyeing wastewater, etc.; as well as the evaporation and crystallization of sodium chloride, potassium chloride, sodium sulfate, sodium sulfite, copper sulfate, magnesium chloride, ferric chloride, ammonium chloride, barium chloride, copper chloride, calcium chloride, nickel sulfate, sodium hydroxide, potassium salicylate, sodium carbonate, zinc sulfate, potassium fluoroaluminate, fumaric acid, manganese sulfate, and ammonium fluoride.

High-value-added manufacturing enterprises have recyclable resources in their wastewater, such as the electronics industry, printed circuit boards, precious metal recovery, and film copying.

During the production process, liquid concentration such as electroplating solution concentration, process concentration, high-concentration liquid incineration pre-concentration, and chemical process concentration, etc.

Machining industry cutting oil.

Operating Principle

The three-effect evaporator crystallizer is conical in shape under the action of the conduit, with the cross-sectional area gradually increasing from bottom to top. Therefore, as the flow moves through the crystallization chamber, the flow velocity decreases. According to the sedimentation principle, crystals, due to their higher density, settle faster. Moreover, the bottom of the evaporation chamber has a conical design to facilitate material sedimentation and discharge. Meanwhile, there is a conduit in the middle of the evaporation chamber, which aids in the separation of solid and liquid materials. Crystals settle to the bottom in the conduit and into the陶析腿 section. The clear mother liquid at the edge of the evaporation chamber is connected to the circulating pipeline and pump. The circulating pump sends the material to the heater, where it is heated and then enters the evaporation separation chamber tangentially, continuously circulating. The crystallized solids are then transferred into the slurry pump for discharge.

Maintenance Instructions

1) Replace the lubricating oil twice within the first month of use, then replace it once every 3-4 months thereafter.

2) After opening the low head, loosen the bolt at the bottom of the rotor U-shaped groove, and inspect and replace the scraper every four months.

3) Every two months, open the bottom bearing and inspect for wear. Replace if necessary.

4) The inner cylinder should be regularly soaked and cleaned with warm water or solvent, based on the material properties.

5) Add sealing fluid to the mechanical seal cavity once a month, using 20# mechanical oil.
