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

Abstract

The invention provides a vertical type multisource steam waste heat recovery energy-saving device, and belongs to the technical field of energy saving and environmental protection. The vertical type multisource steam waste heat recovery energy-saving device comprises an upper liquid storing chamber, a heat exchange chamber, a lower liquid storing chamber, row tubes, a first separating plate, a second separating plate and the like. Inlets for exhaust steam and waste condensate water with different pressures and temperatures are arranged according to the heat exchange gradient, and the problemsabout integrated mixing and recovering of the steam and waste condensate water with different pressures are solved; the multiple layers of separating plates are alternatively arranged for dividing theheat exchange chamber into a plurality of communicated cavities, the heat exchange path is prolonged, and the heat exchange efficiency is further improved; separation of waste gas with large densityis achieved, the handling quantity of the waste gas is effectively reduced, and the energy saving and environmental protection effect is obviously improved; and as an auxiliary adjusting device of anMVR system, the MVR system runs stably and efficiently, and maximized utilization of the waste steam is achieved. The advantages of being high in integration level, simple in structure and low in equipment investment are achieved, the vertical type multisource steam waste heat recovery energy-saving device can be widely applied to waste heat recovery and using of foods, feed, chemical engineering,pharmacy, sewage treatment and other industries and fields.

Description

technical field [0001] The invention relates to a vertical waste heat recovery device, in particular to an energy-saving device with access to multiple heat sources, capable of 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 problems wil...

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
