Building type absorption heat exchange station

Abstract

The invention discloses a building-type absorption heat exchange station, which is composed of an absorption heat exchanger, a water replenishment constant pressure device, a secondary circulation pump, a primary network waterway and a secondary network waterway in the station to form an integrated heat exchange station, and the primary network After the water enters, it is divided into two branches, one branch is connected to the hot side inlet of the absorption heat exchanger, and the other branch is connected to the water inlet of the water supply constant pressure device, and the hot side outlet of the absorption heat exchanger passes through the flowmeter It is connected with the primary water outlet of the heat exchange station; the return water from the secondary network is divided into two branches after entering the water treatment device, one branch is connected to the cold side inlet of the absorption heat exchanger, and the other branch is connected to the water supply and constant pressure The water outlet of the device and the cold side outlet of the absorption heat exchanger are connected to the inlet of the secondary circulation pump, and the outlet of the secondary circulation pump is connected to the secondary water outlet of the heat exchange station. The building-type absorption heat exchange station according to the embodiment of the present invention reduces the return water temperature of the primary network, increases the temperature difference between the supply and return water of the primary network, and makes the hydraulic distribution of the secondary network simpler.

Description

Technical field [0001] The present invention relates to the field of energy technology, particularly relates to absorption heat exchanger or building type field, and more particularly, to a heat absorber building station. Background technique [0002] Due to the requirements of energy conservation, many recycling industrial waste heat as heat source for heating transformation of urban heating program has been rapid development and wide acceptance, the end of the heating stage is still mainly in the form of plate heat exchanger stations were higher district heating, since the plate heat exchanger must have a temperature higher than the net return return temperature of the secondary network, so that the entire system of a net return water temperature, low temperature industrial waste heat is difficult to recover. Meanwhile, a heat transfer station with a multi-mode heating buildings is difficult to achieve sub-dong independent regulation, can not avoid the uneven distribution of co...

Problems solved by technology

[0004] At present, the horizontal absorption heat exchanger, which has been used in many domestic projects, can realize low-temperature primary network return water with centralized pumping station, water supply constant pressure and water treatment device, but its stand-alone capacity is the supply required by a single building. 10 to 30 times the heat, so it can only be installed in a heat station, and cannot realize heating in separate buildings
