Multifunctional vapour recovery warehouse

Abstract

The invention discloses a multifunctional steam recovery bin, wherein, the steam recovery bin is connected separately with a boiler, a circulating water bin and a low pressure bin; a pipe outlet communicated with the circulating water bin, the outlet pipeline of a low pressure wheel to the steam recovery bin, a plurality of air inlets and air outlets are arranged in the steam recovery bin, the air outlets are communicated with the low pressure bin, the steam compression pipe communicated with the circulating water bin is arranged on the air inlet, a plurality of compressors are separately arranged in the air inlet and on the connective position of the steam compression pipe and the circulating water bin. The invention eliminates the steam condenser and the subsidiary system in traditional power generation technology, fully reclaims a large quantity of low temperature and low pressure steam which are originally discharged to the steam condenser, and also fully reclaims the other exhaust steam and condensed water generated by other parts for power generation. The invention is suitable for power plant or the common thermodynamic equipment worked with steam generated by boiler, and has the advantages of extensive application scope, simple and safe structure, environmental protection, energy saving and better popularization value.

Description

technical field [0001] The invention relates to the technical fields of environmental protection, energy saving, emission reduction, consumption reduction, equipment protection, and production safety, and more specifically relates to the technical fields of water and steam discharge, recovery, and power generation equipment. Background technique [0002] At present, the method of using water vapor to drive the turbine generator to generate electricity is the most important power generation technology in the world, accounting for more than half of the world's total power generation. Even in the United States, 90% of its electricity is produced by thermal power, thermal power generation Both nuclear and nuclear power generation use water vapor to drive a turbo generator to generate electricity. Thermal power generation is the largest source of pollution in the world and the largest water consumer in industry. For example, the current water consumption of thermal power generati...

AI Technical Summary

Problems solved by technology

From the figures of the above two plants, it can be seen that the waste of the current power generation process is extremely serious. The heat lost by the condensation of water vapor after doing work into water in the condenser is much more than the heat consumed by driving the steam turbine to do work. Moreover, 1Kg of water vapor is discharged after doing work, and 50-80Kg of cooling water is required

Not only that, but in this process, more than 1 / 3 of the high-temperature and high-pressure water vapor produced in the large boiler circulates in the flow part of the steam turbine and heats the boiler feed water and other links. Before reaching the condenser, it is It becomes the form of condensed water and waste steam and is discharged halfway, causing huge heat loss and a large amount of high-purity water loss

For this reason, a large amount of high-purity water is required to be continuously replenished. During the process of replenishing water, a large amount of non-condensable gas is mixed in, and due to the continuous concentration during operation and heating, the water quality in the thermal system continues to deteriorate, causing Corrosion inside the device

In order to solve this problem, a large amount of chemical agents are needed for water treatment, and the boiler needs to discharge sewage during operation. Even so, it cannot fundamentally solve the corrosion problem inside the equipment. The high-pressure water and water vapor loss causes huge waste, and also produces huge noise, and a large amount of sewage discharge seriously pollutes the environment
