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, which is composed of a heat exchange unit and a PLC control cabinet for complete machine control; the heat exchange unit includes a primary network with a data acquisition device connected to a plate heat exchanger The circulation pipeline and the secondary network circulation pipeline; the data acquisition device is connected to the PLC control cabinet in communication; the secondary network return pipeline on the water outlet side of the secondary network circulation pump group is connected with a secondary network replenishment pump group and the secondary network replenishment pipeline of the first replenishment valve; the secondary network replenishment pipeline on the water inlet side of the secondary network replenishment pump group is connected to the replenishment tank; the primary network water supply pipeline passes through a two-way pump The primary network water supply branch pipe of the second water supply valve is connected to the secondary network water supply pipeline on the outlet side of the secondary network water supply pump group; the primary network water supply branch pipe is connected to the water supply tank through a bypass pipe with a bypass valve; The intelligent control type heat exchange unit of the present invention has high heat exchange efficiency and prolongs the service life of the equipment.

Description

technical field [0001] The invention relates to an intelligent heat exchange unit, in particular to an intelligent control type heat exchange unit, which belongs to the technical field of heat exchange units. Background technique [0002] The heat exchange unit is an important equipment in the heating system, which is responsible for exchanging heat from the primary network circulation to the secondary network circulating water to provide heating for users. Most of the existing intelligent heat exchange units are composed of heat exchangers, frequency conversion circulating pumps, supplementary water pumps, unit pipelines, valves, temperature transmitters, pressure transmitters, intelligent controllers, electric control valves for primary water supply, etc. ; 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 is exchanged in the heat exchanger, and the ho...
