HEAT STORAGE TANK TYPE WASTE-HEAT COLLECTOR USING MULTI-CROSS HEAT EXCHANGE

摘要

PURPOSE: A heat storage tank type waste heat collector using a multi-stage and inter-unit heat-exchanging method is provided to easily push bubbles floating to the upper part of a heat storage tank towards a discharging pipe along the flow path of waste water by using jet force. CONSTITUTION: A thermal storage tank type waste heat collector using a multi-stage and inter-unit heat-exchanging method is equipped with a heat storage tank (2) including a bubble generating device in the lower part inside the tank and a heat-exchanging tube (7) connected to a refrigerant pipe in the upper part inside the tank. The inner space of the thermal storage tank is divided into multiple unit spaces including the bubble generating device and the heat-exchanging tube by lattice-shaped partition plates (10). The partition plate in the upper part, which the heat-exchanging tube is installed in, forms a zigzag-shaped flow path for waste water so that the operation for suppressing scale and collecting heat by aeration is independently performed in each unit space. The inter-unit heat-exchanging of the waste water and the refrigerant passing through the each unit space is gradually and reasonably performed in multiple stages from a low-temperature stage to a high-temperature stage. A three-dimensional inter-unit heat exchanging is performed by circulating the waste water stored in each unit space upwards and downwards through a water flow chamber.
