AI Technical Summary

Technical Problem

When treating high-salt wastewater, existing evaporators cause scale to form on the surface of heat exchange elements, leading to a decrease in heat transfer efficiency and, in severe cases, affecting production. Traditional chemical cleaning methods require shutdown and may corrode the equipment, increasing maintenance costs.

Method used

A movable scraper is installed on the outer wall of the heating tube to remove dirt. Combined with a liquid spray system, this enables online cleaning and avoids corrosion during downtime.

Benefits of technology

This technology enables real-time cleaning of dirt during the operation of heated tubes, extending equipment lifespan, avoiding downtime losses and corrosion problems associated with chemical cleaning, and improving production efficiency and equipment maintenance effectiveness.

Abstract

The utility model provides a horizontal falling film evaporator tube nest self-adjusting descaling device, and relates to the technical field of evaporator descaling devices, the horizontal falling film evaporator tube nest self-adjusting descaling device comprises a heating tube nest and a tube nest cleaning device, the tube nest cleaning device comprises a scraper, the heating tube nest is a square tube, the blade point of the scraper is attached to the plane of the heating tube nest, and the scraper can move back and forth along the heating tube nest; when dirt is attached to the outer walls of the heating tube nests, the scraper scrapes the dirt through the outer walls of the heating tube nests. The evaporator has the advantages that the movable scraper is arranged on the side face of the heating tube nest, dirt attached to the outer wall of the heating tube nest can be scraped off by the scraper, and in the working process of the heating tube nest, the scraper does not need to stop cleaning work on the outer wall of the heating tube nest, so that the working time of the evaporator is not occupied, and the working efficiency is improved. Compared with a chemical cleaning mode, the physical cleaning mode does not corrode the outer wall of the heating tube nest, and dirt can be cleaned in time, so that the evaporator can be better maintained, and the service life of the evaporator is prolonged.
