Problems solved by technology

In the prior art, when the heating temperature of the primary network water supply pipeline is high, the heat source supply on the primary network side can only be reduced by adjusting the opening of the regulating valve set on the primary network water supply pipeline; but when the primary network side When the temperature of the heat source is too high, the high-temperature heat source enters the plate heat exchanger, which will easily damage the internal pipeline of the plate heat exchanger, affect the normal use of the plate heat exchanger, and shorten its service life; and the heat exchange efficiency of the existing heat exchange unit needs improvement

Abstract

The invention discloses an intelligent control type heat exchange unit. The intelligent control type heat exchange unit is composed of a heat exchange unit and a PLC control cabinet used for the wholemachine control; the heat exchange unit includes a primary network circulating pipeline and a secondary network circulating pipeline with a data acquisition device connected with a plate heat exchanger; the data acquisition device is in communication connection with the PLC control cabinet; a secondary network return water pipeline of the water outlet side of a secondary network circulating pumpgroup is connected with a secondary network water supplementing pipeline with a secondary network water supplementing pump group and a first water supplementing valve; a secondary water supplementingpipeline of the water inlet side of the secondary network water supplementing pump group is connected with a water supplementing box; a primary network water supply pipeline is connected with the secondary network water supplementing pipeline of the water outlet side of the secondary network water supplementing pump group through a primary network water supply branch pipe with a two-way pump and asecond water supplementing valve; and the primary network water supply branch pipe is connected with the water supplementing box through a bypass pipe with a bypass valve. According to the intelligent control type heat exchange unit, the heat exchange efficiency is high, and the service life of the equipment is prolonged.

Description

Technical field [0001] The invention relates to an intelligent heat exchange unit, in particular to an intelligent control type heat exchange unit, and belongs to the technical field of heat exchange units. Background technique [0002] The heat exchange unit is an important equipment in the heating system. It is responsible for transferring heat from the primary grid cycle to the secondary grid circulating water to provide heating for users. The existing smart heat exchange units are mostly composed of heat exchangers, frequency conversion circulating pumps, make-up pumps, unit pipelines, valves, temperature transmitters, pressure transmitters, intelligent controllers, and electric control valves for primary water supply. ; Its working principle is: the primary heat source (steam or hot water) is adjusted by the electric valve, and the secondary return water pressurized by the circulating pump exchanges heat in the heat exchanger, and the hot water is sent to the user; and throu...
