Valley energy solid heat accumulation and heating device

Abstract

The invention discloses a valley energy solid heat accumulation and heating device which comprises a high-temperature solid heat accumulation pile, an oil pump system, a heat exchange system and a control cabinet. The high-temperature solid heat accumulation pile is connected with the heat exchange system through the oil pump system. The heat exchange system comprises a high-low temperature heat exchanger, a medium pump system, a low-temperature heat exchanger, a water circulation system and the like, wherein the high-low temperature heat exchanger is connected with the low-temperature heat exchanger through the medium pump system, and the low-temperature heat exchanger is connected with the water circulation system. The control cabinet is connected with monitoring input signals and running output signals in the high-temperature solid heat accumulation pile, the oil pump system and the heat exchange system through cables and lead wires. The valley energy solid heat accumulation and heating device is reasonable in structure, efficient, energy-saving, environment-friendly, stable, safe and reliable and is easy to operate, high in heat accumulation temperature and stable in heat exchange process. In addition, the storage capacity of the whole device is strong, release output is continuous, the duration can be ensured, and the purposes of zero pollution, zero discharge and centralized control are achieved.

Description

technical field [0001] The invention relates to the field of valley energy utilization, and belongs to the technical category of "electric heating", in particular to a valley energy solid heat storage heating device, in particular to a high-efficiency electric heat energy conversion, storage and release equipment assembly. Background technique [0002] The generation, supply, and use of electricity are completed at the same time, and it is difficult to store electricity. If the electricity generated cannot be effectively used, it will be lost in the form of grid heating; therefore, the electricity load varies greatly during the day and night. Under the circumstances, there will inevitably be the so-called low power at night. The valley power loss is not only a loss of resources and economy, but also a technical problem, which makes the problem of power grid peak regulation increasingly prominent, reduces the quality and efficiency of power grid operation, and also affects th...
