Abstract

The present invention provides a flexible generation device through adoption of industrial waste heat and a manufacturing method thereof. Layers of membrane electrodes are made on the upper and lower surfaces of a pyroelectricity thin film, copper conductors are fixed on the upper and lower membrane electrodes through electric conduction silver paste to obtain a flexible heat collection device; a supercapacitor and the flexible heat collection device are connected in parallel, positive and negative electrodes are led out through the copper conductors to obtain a flexible generation unit; the PDMS is dripped on the flexible generation unit to allow the flexible generation unit to be completed wrapped by the PDMS thin film and only expose the copper conductors to obtain the flexible generation device through heating and solidification; at usage, the flexible generation device is pasted at the outer side of a beaker, an ampere meter is connected with the positive and negative electrodes through the copper conductors, different solutions are prepared in the beaker for chemical reaction to realize the different thermal electricity conversion efficiency through controlling the concentration of the chemical reagent and the stirring rate. According to the invention, the flexible generation device through adoption of industrial waste heat and the manufacturing method thereof can allow the waste heat generated in the industrial chemical reaction to perform direct collection and convert into electric energy.

Description

technical field [0001] The invention belongs to the technical field of industrial waste heat utilization, and in particular relates to a flexible power generation device utilizing industrial waste heat and a manufacturing method. Background technique [0002] Many industrial processes are accompanied by heat generation, such as industrial sewage treatment, ammonia and sulfuric acid manufacturing processes, etc. The essence of these processes are chemical exothermic reactions. The most typical example is that the neutralization exothermic reaction of sulfuric acid and lime water is usually used to produce calcium sulfate precipitation, so as to realize the treatment of acid sewage; the three steps in sulfuric acid production are all exothermic reactions: S+O 2 =SO 2 ;2SO 2 +O 2 =SO 3 ; nSO 3 +H 2 O=H 2 SO 4 +(n-1)SO 3 , and the heat generated by each process is 3310.08KJ / mol, 99KJ / mol, and 132.5KJ / mol respectively. Therefore, the waste heat energy generated by indus...
