A hot steam recovery and energy-saving utilization system for steam boilers

Abstract

The invention discloses a hot steam recovery and energy saving utilization system of a steam boiler. The hot steam recovery and energy saving utilization system includes a steam boiler, the top end ofthe steam boiler is connected with a steam turbine through an insulation pipe, and the air outlet end of the steam turbine is connected with a condenser, a descaling device is detachably installed inthe condenser, and the bottom of the condenser is connected with a condensate recovery device through a steam trap; the steam trap includes a water collecting sump, a water inlet pipe and a drain pipe are correspondingly fixedly installed on the left side and the bottom side of the water collecting sump, the upper portion of the drain pipe is provided with an annular sealing groove, and a sealingsupport ring is movably arranged in the annular sealing groove, a sealing float ball is installed on the sealing support ring, a cambered surface sealing plate is arranged on the lower portion of thesealing float ball, and the cambered surface sealing plate is fixedly installed on the inner wall of the annular sealing groove; and the upper portion of the sealing float ball is provided with a limit plate, and the limit plate is fixedly installed on the inner wall of the water collecting sump. According to the hot steam recovery and energy saving utilization system of the steam boiler, the heat energy in the steam can be fully used, meanwhile condensate water can be effectively recovered, and the characteristics of energy saving and high efficiency are achieved.

Description

technical field [0001] The invention relates to the field of energy recovery and utilization, in particular to a hot steam recovery and energy-saving utilization system of a steam boiler. Background technique [0002] A steam boiler refers to an industrial boiler that heats water to a certain parameter and produces high-temperature steam. The water is heated in the drum to become steam, and the fire emits heat in the furnace, which is the principle of the steam boiler. Steam boilers are special equipment. The design, processing, manufacture, installation and use of the boilers must be supervised by the technical supervision department. Users can use steam boilers only after obtaining the boiler use certificate. According to the fuel (electricity, oil, gas), steam boilers can be divided into three types: electric steam boilers, oil-fired steam boilers, and gas-fired steam boilers; according to the structure, they can be divided into vertical steam boilers and horizontal steam...

AI Technical Summary

Problems solved by technology

[0005] (1) The hot steam recovery energy-saving utilization system of the steam boiler in the prior art adopts open heat energy recovery in the process of use, which not only causes the loss of heat energy in the steam, but also causes the loss of water due to the evaporation of hot steam. Defects;

[0006] (2) During the use of the hot steam recovery energy-saving utilization system of the steam boiler in the prior art, the hot steam and the condensed water are not separated well, resulting in the discharge of the hot steam and the condensed water together, resulting in a decrease in the heat recovery efficiency
