Boiling waste steam waste heat recycling device

Abstract

The invention discloses a boiling waste steam waste heat recycling device. Boiling waste steam generated in the production process of a food enterprise is recycled and applied to other production procedures and prevented from being directly discharged; secondary heat exchange is conducted through the boiling waste steam recycling device; and steam generated by a great number of independent steamers is recycled collectively. Primary heat exchange is device surface heat exchange; secondary heat exchange is spray condensation heat exchange; and a majority of heat of the boiling waste steam is recycled, so that energy is utilized cyclically. The large-size food production enterprise demands water at all temperatures; and the recycled heat is wide in purpose and can be applied to multiple purposes such as earlier-stage processing, washing and heat exchange of food. By means of the boiling waste steam waste heat recycling device, food smell in the waste steam of the steamed food is eliminated, and influence, generated when the food enterprise boils the food, on quality of surrounding air is reduced.

Description

technical field [0001] The invention belongs to the field of improving energy utilization efficiency, and relates to the recovery of industrial steam waste steam, that is, the recovery of food cooking steam, which greatly improves the energy utilization efficiency. Background technique [0002] Food companies have a lot of cooking equipment, and a lot of exhaust steam will be generated during the production process. Most of the exhaust steam is discharged to the air. The exhaust steam contains a large amount of latent heat of vaporization and has a high temperature grade. It is discharged into the air. Energy waste is large. [0003] There are a large number of cooking equipment in the production workshop of food enterprises, most of which are independent steamers, with large quantities, but the pots are small, and it is difficult to recycle them independently. [0004] When the steam diffuses to the outside, the smell of cooking food also escapes, and this food smell will ...
