Actual processing capacity matching degree

This indicator is the core prerequisite for adapting production capacity, which requires precise correspondence with the scale of wastewater or material treatment in enterprises, while reserving reasonable flexibility space to avoid capacity waste or equipment overload operation. On the one hand, it is necessary to calculate the precise processing scale by first calculating the material processing demand per unit time, such as chemical enterprises processing 50 tons of high salt wastewater per day, food factories processing 2 tons of concentrated liquid per hour, etc., and then selecting equipment that matches the single machine processing capacity accordingly. If choosing "big horse pulling small car" will result in energy waste, while "small horse pulling large car" will lead to substandard processing and accelerated equipment wear and tear. On the other hand, flexible expansion space should be reserved, taking into account fluctuations such as peak and off peak production seasons and capacity expansion. Modular design equipment should be prioritized. For example, by connecting parallel units, modules can be added according to capacity increase in the future without the need for overall equipment replacement, especially suitable for industries with large capacity fluctuations such as food and electronics. In addition, chemical and new energy enterprises engaged in continuous production need to choose models with strong stability in continuous operation; Intermittent production laboratories or small pharmaceutical enterprises can focus on operating flexible small and medium-sized equipment.

Adaptability of material characteristics

The material characteristics directly determine whether the low-temperature evaporator can operate stably. If the adaptability is insufficient, problems such as scaling, blockage, and equipment corrosion may occur, indirectly leading to the inability to release production capacity normally. The following three points need to be focused on. One is salt content and concentration. If treating low to medium concentration wastewater with a salt content of less than 15%, conventional low-temperature evaporators can efficiently concentrate it; If the salt content exceeds 10% or is close to supersaturation, it is necessary to equip the machine with anti scaling structure to avoid salt analysis blocking the pipeline and affecting treatment efficiency. The second issue is corrosiveness and viscosity. For wastewater containing chloride ions, strong acids, and strong alkalis, equipment made of titanium alloy or fluorine lined materials should be selected. Ordinary 316L stainless steel materials are prone to corrosion and damage, and frequent shutdowns for maintenance are required; When dealing with viscous materials with high viscosity and high COD, priority should be given to low-temperature evaporators with scraping structures to prevent material adhesion to the pipe wall and reduce heat transfer efficiency, ensuring continuous production capacity. The third is thermal sensitivity. Materials in the food and pharmaceutical industries often contain thermosensitive substances such as proteins and pharmaceutical components. It is necessary to choose models with stable evaporation temperatures controlled between 40-60 ℃ to avoid high temperature damage to material components or volatilization of pollutants, while ensuring stable and uninterrupted production capacity during the processing.

Energy efficiency and operational economy

This indicator determines whether the equipment can control long-term operating costs while matching production capacity, avoiding offsetting production capacity benefits due to high energy consumption. The core depends on the type of energy consumption and operation and maintenance costs. From the perspective of energy consumption types, in large-scale stable production capacity scenarios, MVR low-temperature evaporators are preferred. By recovering secondary steam, they consume only 20-40kW · h of electricity per ton of water, with energy consumption only 10% -20% of traditional models. They are suitable for chemical and electroplating parks with a daily processing capacity of over 30 tons; Medium capacity enterprises can choose multi effect low-temperature evaporators to balance energy consumption and initial investment. The steam consumption per ton of water is about 0.4-0.6 tons, suitable for daily processing of 10-30 tons. From the perspective of operation and maintenance costs, long-term costs need to be calculated in conjunction with production capacity scale. For example, the MVR model has a high initial investment, but the compressor maintenance cost is low, with a lifespan of 10-15 years, making it suitable for large-scale long-term stable production capacity; If choosing high priced MVR models for small-scale production capacity, it may not be cost-effective due to the long investment payback period. At the same time, it is necessary to avoid high maintenance models corresponding to materials that are prone to scaling and corrosion. For example, when treating ordinary low viscosity wastewater, a static structure low-temperature evaporator should be selected, which is easy to maintain and has short downtime, ensuring stable output of production capacity.
