Horizontal multi-source steam waste heat recovery energy-saving device

Abstract

The invention provides a horizontal multisource steam waste heat recovery energy-saving device, and belongs to the technical field of energy conservation and environmental friendliness. The horizontalmultisource steam waste heat recovery energy-saving device comprises a liquid inlet chamber, a heat exchange chamber, a liquid outlet chamber, row tubes, a steam isolation plate, a liquid isolation plate and the like. Inlets for waste steam and waste condensate water at different pressures and temperatures are formed according to the heat exchange gradient, so that the problem of integrated mixing and recycling of steam and the waste condensate water under different pressures is solved; the multilayer steam isolation plate is matched with the staggered separation of the row tubes, and the liquid isolation plate is used for adjusting the flow direction of liquid, so that the heat exchange efficiency is further improved; effective separation of the waste steam is realized, the treatment capacity of the waste steam is reduced, and the obvious effects of environmental friendliness and energy conservation are achieved; and the horizontal multisource steam waste heat recovery energy-savingdevice is used as an auxiliary adjusting device of an MVR (mechanical vapor recompression) system, so that the MVR system is stably and efficiently operated, the maximum utilization of the waste steamis realized, and the energy-saving effect is obvious. The horizontal multisource steam waste heat recovery energy-saving device has the advantages of high integration level, the simple structure andlow equipment investment and can be widely applied to waste heat recovery and utilization in the industry and field of food, feed, chemical engineering, pharmacy, sewage treatment and the like.

Description

technical field [0001] The invention relates to a horizontal waste heat recovery device, in particular to an energy-saving device which has access to multiple heat sources and can perform heat exchange and recovery of steam waste heat. It belongs to the technical field of energy conservation and environmental protection. Background technique [0002] Tube and tube heat exchangers, plate heat exchangers, etc. are common heat exchange equipment in chemical, food, pharmaceutical and other fields, and are used to preheat or cool materials. In the application of waste heat recovery and utilization, waste steam is generally used as the heat medium. However, in many evaporation and concentration processes, there are more than one pressure and temperature of waste steam, and in many cases, the temperature of waste condensate is relatively high. There is a certain waste heat recovery value. [0003] Due to the direct mixing of steam with different pressures and temperatures, many p...

AI Technical Summary

Problems solved by technology

Therefore, the conventional technical solution is to use different heat exchange devices for steam with different pressures and temperatures, which takes up a lot of space and requires high equipment investment, and it is difficult to achieve temperature matching for the heated medium, which will also lead to insufficient utilization of waste steam and affect Production efficiency and other issues
