Example Embodiment

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments thereof. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0024] In theory, steam condensate is formed by condensation of steam, and the water quality is extremely pure. However, in practical applications, due to various reasons, condensate water will contain some pollutants. Combined, it can effectively prevent the pollution of condensed water, thereby avoiding the waste of water resources and heat.

[0025] The pollution factors in boiler condensate water are roughly divided into two categories: metal pollutants and organic pollutants. The metal pollutants mainly exist in the condensate water in the ionic state, such as Fe2+, Fe3+, Cu2+, etc. The colloidal state is suspended in the condensed water, and it can also be dissolved in th...

Abstract

The invention discloses a boiler condensed water recovery process, which is characterized in that after the condensed water which is used by a heat application device is collected by a pressure water accumulation tank, the oil content and the alkalinity of the condensed water are detected by an online monitoring device, the condensed water is deoiled by active carbon, then the condensed water enters a soft water tank after being sequentially softened by a cation bed, an anion bed and a mixed bed to reduce the alkalinity, and finally the condensed water is fed into a boiler after being deoxidized by a deoxidized tank. The pressure water accumulation tank is used for collecting the condensed water, the entire process is a closed-type recovery system, oil removal, softening and deoxidization are carried out on the detected condensed water, and then the condensed water is fed into the boiler, so that the recovery utilization rate of the condensed water is improved; and meanwhile, the temperature of the supplied water of the boiler is increased, the boiler efficiency is increased, and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of industrial boilers, in particular to a boiler condensed water recovery process. Background technique [0002] Steam condensate is high-quality boiler water that contains heat energy. The heat contained can reach 20%~30% of the total heat of steam. The quality of condensate water is much higher than softened water and close to pure water. Recycling steam condensed water can significantly reduce boiler fuel consumption, reduce softened water consumption, reduce steam production costs, improve boiler water quality and scaling conditions, and is the most effective measure for boiler water and energy saving. In recent years, facing the serious situation of tense energy supply and demand, many large-scale enterprises have attached great importance to the recycling of steam condensate, but due to the unsatisfactory recovery effect, most enterprises are still on the sidelines. Therefore, how to effectively treat...
