Energy-storage heat exchanger

Abstract

The invention provides an energy-storage heat exchanger used for condensing and cooling intermittent water vapor or high-temperature smoke. The energy-storage heat exchanger comprises a heat exchangershell and energy-storage heat exchange tubes penetrating through the heat exchange shell in parallel. Each layer of energy-storage heat exchange tubes are arranged between perforated pattern plates.Connectors of each layer or multiple layers of energy-storage heat exchange tube bundles are combined to be connected to a main tube box. A communication tube is connected between an inlet and an outlet of each upper main tube box and the adjacent lower main tube box, so that all the layers of energy-storage heat exchange tube bundles are connected in series or in parallel. Water vapor or high-temperature smoke enters shall passes of the energy-storage heat exchange tubes in the heat exchanger to be cooled, and cooling water enters tube passes of the energy-storage heat exchanger. According tothe energy-storage heat exchanger, water vapor or high-temperature smoke which is intermittently generated can be continuously cooled, and the problem that cold medium heat and hot medium heat are not balanced at the same time is solved.

Description

technical field [0001] The invention relates to technical fields such as metallurgy, chemical industry, and thermoelectricity, and in particular relates to an energy storage heat exchanger. Background technique [0002] Existing heat exchangers used in the fields of metallurgy, chemical industry, and thermoelectricity are mostly continuous heat medium that is continuously cooled to a certain temperature by the cold medium through the heat exchanger, and the heat brought in by the two media at the same time is balanced by the heat taken out According to the characteristics of the medium and the technical requirements of the process, the widely used tube and tube heat exchangers, spiral plate heat exchangers, plate heat exchangers, coil heat exchangers, heat pipe heat exchangers, etc. can be used. However, in actual industrial production, some cooled media are produced discontinuously, and the amount of instantaneous generation is large. The heat brought in by the hot medium i...

Problems solved by technology

During the production process of coke oven charging, coke discharge, coke CDQ and coke charging, a large amount of high-temperature flue gas is emitted in each operation. The existing technology generally adopts the method of mixing a large amount of air or using metal materials to absorb heat and then use air The method of cooling metal materials cools high-temperature flue gas, and the heat energy of high-temperature flue gas is not recovered and utilized
