Building block system low air-resistor condenser assembly and technology

Abstract

A traditional water cooling surface condenser for thermal power generation of a steam turbine cools and converts worked high-quality middle-pressure low-pressure steam heat energy into a large amount of low-temperature waste hot water through a large amount of cooling water, and dissipates the waste hot water to the surroundings, and pollution is caused. In order to achieve the purpose of recycling and obtaining 95% or more high-temperature waste heat recycling benefits from waste heat, a novel stepped temperature increase high temperature conversion condenser needs the heat exchange area more than multiple times the area of an old condenser technically, and therefore air resistance is increased. In order not to change the air resistance, namely, the power generation efficiency, of an existing steam turbine, novel technologies and materials need to be adopted. Stainless steel materials are adopted for mechanical stamping to form a low air-resistor fish-type heat exchange pipeline, a building block system split heat exchange assembly is formed and can form a water-way channel split assembly with a spiral channel, and the stepped temperature increase high temperature condenser is formed in a building block system mode. According to the technology, high-temperature efficient waste heat recovery of condensation thermal power generation can be achieved, the material and technological cost can be greatly lowered, and the quite important significance is achieved for standardizing and unifying condenser basic assemblies of different powers.

Description

technical field [0001] The invention belongs to the field of thermal power generation, and relates to a building block type low air resistance condenser assembly and a process. Background technique [0002] The condenser is the main equipment of most steam turbine thermal power generation technologies. Taking the water-cooled surface condenser as an example, in order to obtain circulating condensed water and maintain the effective Rankine cycle of the steam turbine, the traditional condenser uses a large amount of cooling The water is forced to convert the high-quality medium-low pressure steam that is still in high-quality low-pressure steam after the work has been done, and convert it into low-temperature waste hot water for high-speed cooling. In order to maintain continuous cooling circulation, the low-temperature temperature difference heat in the cooling water needs to be dissipated to the surrounding environment of the power plant, resulting in local Or thermal pollut...

Problems solved by technology

For this reason, technically, the new condenser requires a heat exchange area several times larger than that of the old condenser, which will inevitably lead to an increase in air resistance. Change, need to change heat transfer form and heat transfer material
