Технические решения по предотвращению теплового загрязнения водоемов в пределах урболандшафта

Abstract

Objective: The development and scientific substantiation of technical solutions for prevention thermal pollution of cooling pond of power facilities. Methods: Patent study, methods of system analysis. Results: Found that cooling ponds in which discharged heated water from electric power facilities, leading to thermal pollution. In connection with which the waters become unfit for housing and communal services, namely drinking and domestic water supply and recreational water use. The existing technical solution for preventing thermal pollution of water bodies have a number of drawbacks, namely low reliability due to the complexity and bulkiness of the structure; limited functionality due to not fully using the heat medium and long cold water. On the basis of the patent study of existing methods of reducing thermal pollution, the developed heat exchanger heated waters of power objects (patent RU № 134621). Designed heat exchanger characterized by enhanced functionality available ways to prevent thermal pollution due to the use of thermal energy of the heated waters of power plants for heating of cold water and correspondingly cooling the heated waters. Practical importance: The proposed by authors technical solution allows utilizing the heat energy of the heated waters of power facilities before discharge into cooling ponds. Thus, the heat exchanger prevents thermal pollution of the reservoir and consequently provides a desired level of water quality for water supply and supplies the consumers with warm water, i. e., contributes to several tasks of housing and communal services.
