Heat supply technique for high temperature water

Abstract

The invention is a new technique of heat supply by high-temperature water, the branch line water supply pipe terminal of the heat supply network is connected with the main user, there is high-temperature water for the user in the supply pipe, there is a branch line return pipe covered on the branch line water supply pipe, one end of the return pipe is connected with the cold water circulating pipe of the main user, there is cold circulating water in the return pipe, and the other end of the return pipe is connected with the water supply circulating pipe of another sub-user. In a station or an underground well, it uses the method that the supply and return pipes are covered together to act as a heat exchanger to reduce the water temperature for the user, and the return water is heated by the high-temperature in the supply pipe and then supplied to another user for heating. It and reduces heat network operating expense, reduces use cost, reduces heating expenses, able to largely increase economic benefits.

Description

technical field [0001] The invention relates to a new heat supply process, in particular to a new high temperature water heat supply process. Background technique [0002] The winter in northern my country is relatively cold, and the winter heating period in some areas is about six months. In the large and medium-sized cities in the north, central heating is basically used for heating in winter, and radiators are driven through the transmission pipes of the central heating network. Indirect heating with high-temperature water is a main method used in central heating systems, that is, output high-temperature water from the heat source to the heat exchange station for secondary heat exchange, and then turn it into low-temperature water to supply heat to users. High-temperature water is changed to low-temperature water, so a lot of necessary equipment is required to be invested in the thermal station, including heat exchangers, circulating water pumps, water replenishment syst...

Problems solved by technology

Indirect heating with high-temperature water is a main method used in central heating systems, that is, output high-temperature water from the heat source to the heat exchange station for secondary heat exchange, and then turn it into low-temperature water to supply heat to users. High-temperature water is changed to low-temperature water, so a lot of necessary equipment is required to be invested in the thermal station, including heat exchangers, circulating water pumps, water replenishment systems, etc., and problems such as water and electricity must be solved. The cost of turning high-temperature water into low-temperature water is relatively high. High, the heat exchange station investment will reach 10 yuan / square meter, not only that, the heat exchanger circulation pump of each heat exchange station must run, and the annual operating cost will also be 1 yuan / square meter, such a high operating cost, serious Affect the efficiency of enterprises, but also increase the economic burden of people
