Abstract

The invention discloses a low temperature waste heat generating set using dead steam of a paper mill and relates to low temperature waste heat generating sets. The low temperature waste heat generating set comprises a dead steam separating air cylinder, a drying roller and a generator set; the dead steam separating air cylinder is connected with the drying roller and the generator set by pipelines respectively, the generator set is connected with the drying roller and a condensed water pump by pipelines, and the generator set is also connected with and controls a grid connection cabinet to realize grid connection operation. By the aid of the low temperature waste heat generating set, heat energy can be recycled to the maximal extent, the heat energy is converted into electric energy, and the problem of waste of energy and water resources existing in a papermaking industry is solved; and the set realizes unattended full-automatic operation in an operation process and is safe and reliable.

Description

technical field [0001] The invention relates to a low-temperature waste heat power generation device, in particular to a device for generating electricity by using steam generated in the drying process of a paper mill. Background technique [0002] In the traditional paper industry, an essential process is the wet paper sheet drying process. The superheated high-pressure steam generated by the boiler in the drying process enters the dryer to cool and then is discharged. In the case of ensuring the quality of the produced paper, automatic control is adopted. Intake of superheated steam, but there is still a part of high-pressure steam that cannot be condensed into water, and there is a phenomenon of high-temperature steam-water mixing at the outlet of the dryer discharge pipe. The high-temperature steam and water are mixed into the boiler reservoir, and the water can flow into the reservoir, but the steam is not released into the air, resulting in the loss of softened water. ...
