Horizontal-type high temperature heat-storage heat supplying equipment and using method thereof

Abstract

The invention discloses horizontal-type high temperature heat-storage heat supplying equipment and a using method thereof. The horizontal-type high temperature heat-storage heat supplying equipment comprises a heat storage tank filled with a heat storage medium; the bottom of the heat storage tank is provided with an electric heating device for heating the heat storage medium, and the electric heating device is connected with an electricity supplying system; a heat exchanging device with an adjustable heat exchanging area is horizontally arranged on the upper part of the heat storage tank in apenetrating mode, and the heat exchanging device is composed of a heat releasing medium inlet section, a heat exchanging section and a heat releasing medium outlet section which are connected in series; and the heat exchanging section is composed of a plurality of heat exchangers which are connected in series and / or in parallel, all the heat exchangers are arranged from bottom to top, the heat exchanger at the very bottom is connected with the heat releasing medium inlet section, and a valve group is mounted on the heat exchanging section and used for controlling a heat exchanger to work or controlling the multiple heat exchangers to work simultaneously. According to the horizontal-type high temperature heat-storage heat supplying equipment and the using method thereof, heat is stored byutilizing off-peak electricity during night or abandoned wind and light 'waste electricity', and steam is produced in daytime, so that entropy production is reduced, the energy utilization efficiencyis enhanced, the electricity transmission capacity of a power grid is increased, and the cost of steam production is reduced substantially.

Description

technical field [0001] The invention relates to the technical field of effective utilization of high-temperature heat storage and heat supply, in particular to horizontal high-temperature heat storage and heat supply equipment and its use method. Background technique [0002] In recent years, the problem of smog has attracted unprecedented attention. An effective way to solve the smog problem is to promote the adjustment of energy structure. The use of renewable energy is listed as a key development direction in the National Climate Change Plan (2014-2020). [0003] At this time, a small thermal storage heating equipment is developed to make full use of the "garbage power" of abandoned wind and solar energy and the low-peak electricity at night. The heat storage medium is used to store the low-valley electricity at night in the form of heat energy for use in the daytime. Heating in winter and industrial steam generation can not only effectively solve the disadvantages of i...

Problems solved by technology

[0003] At this time, a small thermal storage heating equipment is developed to make full use of the "garbage power" of abandoned wind and solar energy and the low-peak electricity at night. The heat storage medium is used to store the low-valley electricity at night in the form of heat energy for use in the daytime. Heating in winter and industrial steam generation can not only effectively solve the disadvantages of increasing the peak-to-valley difference in the power grid caused by the current comprehensive ban on small coal-fired boilers and replace them with electric boilers, but also have very important significance for improving the economic benefits of small enterprises. To a certain extent, it can effectively alleviate the current haze weather and has a good application prospect.
