Waste steam recovery and utilization device

Abstract

The invention relates to a waste steam recovery and utilization device which comprises a steam absorption tower, a mixing barrel and a PLC controller; the bottom of the steam absorption tower is connected with a gas inlet pipe for inputting steam into the steam absorption tower; the steam absorption tower is internally provided with a nozzle component for spraying misty cold water upward and changing the misty cold water into hot water by being subjected to heat exchange with steam; the bottom of the steam absorption tower is connected with the mixing barrel through a descending water pipe and conveys the hot water to the mixing barrel; and the PLC controller is arranged on the outer side of the steam absorption tower and controls the hot water in the mixing barrel through the temperature of the hot water in the mixing barrel to continuously carry out heat exchange with the steam in the steam absorption tower for rising temperature or directly discharges the hot water for use. The waste steam recovery and utilization device has the beneficial effects of simple structure, convenience in use, little investment, and capabilities of effectively recovering waste steam and achieving the purpose of energy conservation.

Description

technical field [0001] The invention relates to the field of energy recovery and utilization, in particular to a waste steam recovery and utilization device. Background technique [0002] At present, the sugar factory is a production enterprise that consumes steam and electricity at the same time, so the sugar factory will be equipped with a thermal power plant, a back pressure turbine generator, and a boiler that burns bagasse to generate steam to generate electricity for the entire production process. The remaining steam generated by power generation, commonly known as "waste steam" in sugar factories, is all used for heating, evaporating, boiling sugar and other process steam in sugar production. Generally, when a sugar factory is just started up, there is no sugar juice material treatment in the production process, so there is no need to consume "waste steam", but a large amount of "waste steam" is directly discharged out of the atmosphere, and the boiler water does not ...

AI Technical Summary

Problems solved by technology

Generally, when a sugar factory is just started up, there is no sugar juice material treatment in the production process, so there is no need to consume "waste steam", but a large amount of "waste steam" is directly discharged out of the atmosphere, and the boiler water does not have high-temperature condensate Only cold water can be used, bagasse is squeezed for infiltration, lime disinfection, etc. If there is no hot water, only cold water can be used. Many other production links use cold water, which consumes a lot of energy and causes energy waste.
