On the project

Zvýšení přenosu tepla a energeticky optimalizovaná integrace výměníků tepla v chemických provozech zvýší využití odpadního tepla. Podle podmínek zařízení je možné zvýšit energetickou účinnost systému a je možné provádět různé způsoby: přímo znovu použít nízké teplo, přeměnit ho na elektrickou energii nebo vysokou chladicí energii a optimalizovat energetickou integraci systému. Využití nízkopotenciálního tepla je účinným prostředkem pro úsporu energie a snížení skleníkových plynů ve velkých podnicích. 1) Navrhuje se kombinovat metodu kontinuálního spirálového spouštění s tlakovým průtokem s cílem dále zlepšit strukturu výměníku tepla s pláštěm a trubkou, zlepšit komplexní výkon tepelného výměníku a snížit ztráty energie; 2) Na základě rozmanitosti zdroje odpadního tepla, typu cirkulačního média a technických provozních parametrů budou vyvinuty metody a normy pro diferencované kontinuální spirálové přepážky výměníku tepla a vytvoří standardizovaný konstrukční rámec, který položí základ pro praktické využití výzkumu a výsledky vývoje; 3) Pro snížení dopadu na životní prostředí bude provedena optimalizace optimálního systému čištění plynů. 4) Síť výměníků tepla a energetická integrace systému pro chemické lokality budou analyzovány a optimalizace tepelné integrace bude vyvinuta pro maximalizaci ekonomické výkonnosti a minimalizaci emisí.

Description in English
The key scientific issues to be solved in this study are as follows: 1) It is proposed to combine the continuous spiral push-flow enhanced heat transfer method to further improve the structure of the shell-and-tube heat exchanger, improve the comprehensive performance of the heat exchanger and reduce the energy loss. 2) Based on the diversity of waste heat source, circulating medium type and technical operation parameters, concepts, innovative heat exchanger designs and integration procedures will be developed. One such is the continuous spiral baffle heat exchanger design, for which methods and standards will be developed, forming a standardised design framework and laying the foundation for the practical application of research and development results. 3) The heat exchanger network and system energy integration in the chemical system will be analysed, and the thermal integration optimisation method will be further developed to exploit the improve the thermal joint utilisation rate of the production system. As a result, it is planned that the proposed project will deliver simultaneously research results and a heat recovery optimisation software package: (1) Three software modules united in a package (2) Minimum 5 publications in Impact-Factor journals (3) Each of the software modules will be accompanied with documentation, comprehensive tutorial and worked examples for user guidance.
