An Absorption Heat Exchanger That Can Realize Multi-zone Independent Heat Supply

Abstract

The invention discloses an absorption heat exchanger capable of realizing multi-zone independent heat supply, which belongs to the field of energy saving; The outlet of the hot water pipeline of the generator is connected with the main inlet of the hot water exchange pipeline of the water-water plate, and the general outlet of the hot water exchange pipeline of the water-water plate is connected with the inlet of the hot water pipeline of the evaporator; the hot water pipeline of the water-water plate is connected It is connected to the heat exchange side of the water-water plate at all levels; the partitioned cold water pipeline inlets of each level are divided into two routes, one of which is connected to the condenser and the absorber, and the other is connected to the cooling side of the water-water plate, and the two routes converge to each Level partition cold water pipeline outlet. The present invention achieves the purpose of heating multiple independent secondary waterways through multi-stage independent absorption heat exchange processes and multi-stage independent cold water pipelines, and multiple secondary waterways are capable of independently adjusting flow, temperature and pressure conditions They do not affect each other, avoiding the series pressure situation between different pressure waterways.

Description

technical field [0001] The invention belongs to the technical field of energy saving, in particular to an absorption heat exchanger capable of realizing multi-region independent heat supply. Background technique [0002] Lithium bromide absorption heat exchanger is a new type of heat exchange equipment, which is currently widely used in the central heating system in the northern region to complete the heat exchange process from the high-temperature hot water in the primary network of the terminal thermal station to the hot water in the secondary network. Compared with the traditional system using various conventional heat exchangers, the use of absorption heat exchangers can greatly reduce the return water temperature of the primary network, improve the temperature difference between the supply and return water and the heating capacity of the pipe network, and achieve clean heating. Since the secondary network is a pipe network connecting the thermal station and each heat ex...
