Absorption heat exchanger capable of realizing multi-area independent heat supply

Abstract

The invention discloses an absorption heat exchanger capable of achieving multi-area independent heat supply, and belongs to the field of energy conservation. A generator hot water pipeline is forwardly connected with generators at different stages, and a evaporator hot water pipeline is reversely connected with evaporators at different stages; a generator hot water pipeline outlet is connected with a water-water plate heat exchange water pipeline main inlet, a water-water plate heat exchange water pipeline main outlet is connected with an evaporator hot water pipeline inlet, and a water-waterplate heat exchange water pipeline is connected with water-water plate heat exchange sides at different stages; and partition cold water pipeline inlets at different stages are divided into two paths, one paths are connected with condensers and absorbers, the other paths are connected with water-water plate cold exchange sides, and the two paths are converged to partition cold water pipeline outlets at different stages. According to the absorption heat exchanger capable of achieving multi-area independent heat supply, the purpose of heating a plurality of independent secondary water paths isachieved through a multi-stage independent absorption heat exchange process and independent cold water pipelines at a plurality of stages, and the plurality of secondary water paths have independent conditions of adjusting flow, temperature and pressure and do not affect one another, so that the pressure mixing condition between the water paths with different pressure is avoided.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to an absorption heat exchanger capable of realizing multi-zone independent heat supply. Background technique [0002] Lithium bromide absorption heat exchanger is a brand-new heat exchange equipment, which is currently widely used in central heating systems in northern regions 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 of the pipe network and the heating capacity, and achieve clean heating. Since the secondary network is the pipe network that connects the heat station and each hea...
