A multi-layer hot water storage tank, a thermal energy recovery and reuse system and a reuse method thereof

Abstract

The invention discloses a multi-layer hot water storage tank, which comprises: an inner tank, at least one middle tank, and an outer tank nested sequentially from inside to outside; water outlets are arranged at the bottom of the inner tank, the middle tank and the outer tank; The inner tank, the middle tank and the outer tank are separated by a heat insulation layer; the inner tank, the middle tank and the outer tank are all equipped with temperature sensors; the through holes on the tank walls of the inner tank and the middle tank make the water in the tank communicate; The tank is provided with a heating pipe; the outer tank is provided with a water inlet. The invention also discloses a heat energy recovery and reuse system and a reuse method thereof, which are used to recover and reuse heat energy in the heat-absorbing process and / or exothermic process. The multi-layer hot water storage tank is used as a heat source, and the waste heat after heating is returned to the collection water tank; the multi-layer hot water storage tank replenishes water from the collection water tank; the heat generated by the exothermic process can also be used to heat the clean water for production, and the collected water is injected into the preheated clean water storage tank for production use , to reduce energy consumption; through these ways to manage the energy and make comprehensive use of it, the total energy consumption can be greatly reduced, which is suitable for a wide range of applications.

Description

technical field [0001] The invention belongs to the technical field of energy recovery and reuse, and in particular relates to a multilayer hot water storage tank, a heat energy recovery and reuse system and a reuse method thereof. Background technique [0002] A chemical synthesis pharmaceutical factory or traditional Chinese medicine pharmaceutical factory with multiple products consumes a lot of energy in production, a large amount of which is heat energy. For example, heating is required for chemical reactions, as well as distillation of liquids, extraction of traditional Chinese medicine components, concentration of aqueous solutions, and evaporation of solvents. Processes such as spraying and recycling of aggressive chemicals also require cooling. Also, some product drying processes (such as fluidized bed dryers, spray dryers, etc.) produce a large amount of high-temperature waste gas, and some processes release a lot of high-temperature waste water (such as the bath ...

and so on, the energy loss due to individual reactions is very considerable

Moreover, more importantly, sometimes the temperature control does not meet the temperature required by the process, which affects the quality of the product or causes environmental pollution (such as ammonia recovery, if the temperature is not low enough, the ammonia recovery efficiency will be affected, and it will be discharged to pollute the environment)
