Embodiment Construction

[0017] The embodiment of the present invention is to lead the process circulating water of the production enterprise to the plate heat exchanger. After the heat in the process circulating water is extracted by the plate heat exchanger, it is returned to the production process. The low-temperature heat source water on the other side of the plate heat exchanger After absorbing the heat in the process circulating water, it is transported to each end user. A heat pump unit is installed at each end user, and the heat is extracted through the heat pump unit for heating by the user.

[0018] The present invention includes a process circulating water supply pipeline 7 , a process circulating water return pipeline 8 , a low-temperature heat source water supply pipeline 9 , a low-temperature heat source water return pipeline 10 , a plate heat exchanger 2 and a plurality of heat pump units 6 .

[0019] As shown in the figure, the input end of the process circulating water supply pipe 7 an...

Abstract

The invention discloses a distributed heat pump heating system utilizing circulating water waste heat, and belongs to the technical field of industrial waste heat heating equipment. The system is used for heating by utilizing the circulating water waste heat in industrial production. The system adopts the technical scheme that an input end of a technology circulating water supply pipeline and an output end of a technology circulating water return pipeline are connected with a heating part of a plate heat exchanger; an output end of a low-temperature heat source water supply pipeline and an input end of a low-temperature heat source water return pipeline are connected with a heat exchange part of the plate heat exchanger; a plurality of heating substations are connected in parallel in the low-temperature heat source water supply pipeline and the low-temperature heat source water return pipeline; and a heat pump unit is mounted in each heating substation. According to the system, a heating main pipe network transports low-temperature heat source water, so that the long-distance main pipe network laying cost and heat loss of the low-temperature heat source water of the main pipe network are reduced; and central heating is performed by combining distributed transport and a distributed heat pump, so that low-grade industrial waste heat is recycled, waste heat and exhaust gas emission is reduced, and the system has a significant economic benefit.

Description

technical field [0001] The invention relates to a heating system utilizing waste heat of circulating water in industrial production, and belongs to the technical field of industrial waste heat heating equipment. Background technique [0002] With the rapid development of the economy, the consumption of energy is also increasing day by day. In order to save energy and reduce pollutant emissions, it is necessary to effectively improve energy utilization. Waste heat recovery is an important link in measures to improve energy utilization, but at present, waste heat recovery in many enterprises is limited to high-grade waste heat resources. Low-grade waste heat Due to its low grade and difficult recovery, a large amount of waste heat is wasted. Central heating is an important aspect of waste heat utilization. At present, the heating pipe network for central heating is becoming larger and more complex. The traditional valve adjustment method is a serious energy waste, poor adjust...
