Steam Utilization Condensate Water Recovery System in Silk Workshop of Cigarette Factory

Abstract

Steam utilization condensate recovery system in the silk workshop of cigarette factory, including boiler (100), deaerator (101), softened water station (102), regular blowdown expansion tank (103), high temperature process equipment (104), low temperature process equipment (105), combined air conditioner (106), flash tank (107), high-pressure condensate recovery tank (108), low-pressure condensate recovery tank (109), first iron removal equipment (110) and second iron removal equipment ( 111). The present invention forms a relatively complete closed cycle from the steam produced by the boiler until the steam is condensed into water and then recycled into the boiler. pollution of the environment.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a steam utilization condensed water recovery system in a shred workshop of a cigarette factory. Background technique [0002] Vacuum dampening, stem moistening, leaf moistening, flavoring and adding materials in the tobacco factory's silk workshop require a lot of steam to heat and humidify the leaves and shredded tobacco, and the process equipment produces a large amount of condensed water during the heating process. Silk workshops, silk storage rooms, and wrapping workshops have strict requirements on ambient temperature and humidity, and a large number of combined air-conditioning units are installed. The combined air-conditioning units use steam to raise the ambient temperature and produce a large amount of steam condensate. The steam inlet pipe also produces a large amount of condensed water due to heat dissipation during steam delivery. Due to the ...

AI Technical Summary

Problems solved by technology

Due to the high temperature and purity of the condensed water discharged from process equipment, combined air-conditioning units, steam inlet pipes, etc., direct discharge will affect the environment and cause waste of heat energy and water resources

If the condensed water is recovered, the pressure and temperature of the discharged condensed water are different due to the different steam pressures in the process equipment, combined air conditioner, and steam inlet pipe. In this way, when the condensed water is recovered, the high-pressure condensed water will hinder the normal discharge and discharge of the low-pressure condensed water. Recycling, and the traditional recycling method cannot completely recover the condensed water, or even if the condensed water is recovered, the flash steam generated by the condensed water is discharged, and the water or flash steam cannot be fully utilized
