Embodiment Construction

[0017] This implementation mode provides an example to further illustrate the present invention.

[0018] In one embodiment, the filter system suitable for heat exchange and purification in power plants includes a closed ditch, which has an inclined flat-shaped upper cover 1, and an insulating layer is laid on the outer surface of the upper cover 1, along which the upper cover 1, a number of condensed water drainage channels are opened on it, and the drainage channels converge in the water guide groove 2 placed on the inclined bottom edge of the upper cover 1, and hermetic doors are installed at both ends of the airtight ditch. , the water guide groove 2 stretches out from the airtight door. During the heat exchange process, a large amount of water vapor will condense into condensed water on the upper cover 1, which is generally considered as a kind of recyclable clean water. In order to recycle this part of water, the upper cover 1 is set as a flat-shaped inclined upper Cove...

Abstract

The invention discloses a filter method applied bale to power plant heat exchange and purification and belongs to the field of power plants. For solving the problem of the influence of impurities on heat exchange, the filter method is technically characterized in that a filter system for heat exchange and purification is used for heat exchange and purification filter, a group of U-shaped PE medium water return pipes are laid in a lower horizontal cover of a channel, the U-shaped PE medium water return pipes are uniformly distributed in a semi-surrounding mode, gaps are filled with sand densely, the PE medium water return pipes are provided with circulating pumps and are communicated with a medium water storage tank, and control valves are installed on communicating pipelines.

Description

technical field [0001] The invention belongs to the field of power plants and relates to a filtering method suitable for heat exchange and purification in power plants. Background technique [0002] Power plants need to use cooling water to cool the steam. Generally, the cooling water of power plants comes from cooling towers, while offshore power plants can directly introduce seawater as cooling water to cool the steam to achieve the purpose of local materials. The completion of steam condensation of seawater will increase its own heat. For example, in winter in Dalian, the temperature of the seawater that should be condensed will reach about 18 degrees. Generally, power plants will return this part of seawater to the sea. However, this method will cause seawater thermal pollution, and also The heat of the power plant is wasted in vain. Using heat exchange means to recycle the heat to realize the utilization of waste heat is a technical means to solve the above problems. H...
