Embodiment Construction

[0037] The present invention will be further elaborated and described below with reference to the accompanying drawings and specific embodiments.

[0038] like figure 1 , figure 2 , Figure 4 , Figure 5 As shown, there are four implementation forms of the regenerative steam heating network heating system with large load fluctuations in the present invention. The difference is the form of the heating heating network (tree heating network or ring heating network) and the thermal The connection position of the heating system module 3 (on the branch user side or on the heating main pipe side). However, the basic structures of the four regenerative steam heating network heating systems with large fluctuations in load are similar, including heating heat source 1, steam heating pipe network module 2, regenerative heating system module 3, and electric heating system module. 4 Four major modules. The heating source 1 is connected to the steam heating pipe network module 2 . The ...

Abstract

The invention discloses a heat storage type steam heat network heating system with large fluctuations in load, which comprises a heat supply heat source, a steam heat supply pipe network module, a heat storage heat supply system module, and an electric heating system module. On the one hand, the present invention proposes to use the high-temperature heat storage energy storage system to realize the storage and release of surplus heat network steam, realize the efficient utilization of steam heat energy in the heat network, and use the electric heat storage superheater as the secondary heat source to solve the problem of heat storage and storage. The problem that the steam temperature decreases during the release process ensures the grade of the heating steam. On the other hand, a method of using heat storage technology to realize local heating is proposed, which solves the problem of poor economy of the steam heating network under low load conditions, and avoids local water hammer due to excessive condensed water caused by excessive heat loss. The problem of safety risk improves the economy and safety of steam heating network operation. At the same time, the heat storage system supplements and increases the heating capacity of the heating network during peak load, and the load capacity of the heating network.

Description

technical field [0001] The invention relates to the fields of heat storage heating technology and new energy power generation technology, in particular to a heat storage type steam heating network heating system and method with large load fluctuations. Background technique [0002] With the development of district heating and central heating, relying on the waste heat steam of large power plants to provide central heating to meet the steam demand of industrial parks, instead of small boiler heating units, is not only conducive to the emission of combustion pollutants, but also reduces heating costs. , it is of positive significance to improve the efficiency of the power plant. [0003] It should be pointed out that, with the advance layout of the heat network, due to insufficient heat users in the early stage of the heat network and large fluctuations in the energy load of local heat users, it is possible to cause insufficient heat network load or large load fluctuations.
