After heat power station heat system for performing vacuum deoxidization using steam turbine condenser

Abstract

A waste heat power station thermodynamic system processing the vacuum deoxygenation with a steam turbine condensator is a vacuum deoxygenatiom system using the chemical deionization water inside a condensator (2) connected with a stream filling and condensing steam turbine (1) for entering an AQC waste heat boiler (13) and a SP waste heat boiler (12) for water supply, which can markedly raise the waste heat utilance. The condensed water of 41-36 degrees can enter the water heating zone of the water heat boiler, heat the condensed water higher than 170 degrees, and reduce the discharging temperature of the waste gas to 100 degrees or so, which reasonably increases the recovery waste heat utilance.

Description

Technical field: [0001] The invention relates to a thermodynamic system of a vacuum deoxygenation waste heat power station, in particular to a thermodynamic system of a vacuum deoxygenation waste heat power station using a steam turbine condenser. Background technique: [0002] ①. The National Development and Reform Commission requires enterprises to adopt ten energy-saving measures. Article 3 stipulates that "the waste heat and pressure generated in the production process should be recycled and rationally utilized." For example, iron and steel enterprises use dry coke quenching sensible heat recovery power generation, blast furnace top pressure difference power generation, blast furnace, coke oven, converter gas recovery power generation, new dry process cement production line kiln head, kiln tail exhaust gas waste heat power generation, etc. Energy conservation and environmental protection, the realization of the concept of circular economy, the corresponding guidelines an...
