Intelligent variable frequency heating exchange station

Abstract

The invention discloses an intelligent variable frequency heating exchange station which is mainly composed of a shell-and-tube heat exchanger, a plate heat exchanger, a condensate pump, a condensate water storage tank, a make-up pump, a circulation pump and a control cabinet. A primary inlet of the shell-and-tube heat exchanger is connected with a steam pipe, and a primary outlet of the shell-and-tube heat exchanger is connected with a series connection pipe to be connected with a primary inlet of the plate heat exchanger. A primary outlet of the plate heat exchanger is connected with a drain pipe to be connected with the condensate water storage tank. A secondary inlet and a secondary outlet of the plate heat exchanger are connected with a secondary water returning pipe and a secondary water supply pipe respectively. The circulation pump is arranged on the secondary water returning pipe, and the secondary water returning pipe is further connected with a temperature reducing circulation pipe behind the circulation pump to be connected with a secondary inlet of the shell-and-tube heat exchanger. A secondary outlet of the shell-and-tube heat exchanger is connected with a temperature reducing water supply pipe to be connected with the secondary water supply pipe. The intelligent variable frequency heating exchange station has the advantages of being complete in system arrangement, capable of achieving energy saving and emission reduction, safe, high in reliability, good in intelligence, convenient to popularize and the like.

Description

technical field [0001] The invention relates to the technical field of heat exchange stations, in particular to an intelligent frequency conversion heating and heat exchange station. Background technique [0002] The heat exchange station has been widely used in many residential areas, shopping malls, hotels, schools, factories and other occasions due to its advantages of less land occupation, flexible use, and good energy saving and emission reduction effects, and it mainly uses plate heat exchangers for heating and cooling. However, because the plate heat exchanger is affected by factors such as poor heat resistance and high temperature resistance of the sealing strip, the application of the plate heat exchanger will be limited under the condition of using high temperature steam, usually when the steam temperature exceeds 150 °C , Do not use plate heat exchangers for heat exchange, otherwise it will endanger safety. Contents of the invention [0003] The purpose of the ...
