Abstract

The article discusses the installation and the hydrodynamic results analysis of three-phase fluidized bed experimental studies. An energy coefficient linear dependence of the circulating water evaporative cooler of the considered type on the irrigation coefficient has been experimentally established. The dependence of the fraction of circulating water evaporated moisture in an evaporative cooler of the type under consideration on the cooled water temperature at the inlet to the cooler and the irrigation coefficient has been established. The analysis of hydrodynamic and thermal processes occurring in a three-phase fluidized bed is carried out, and the main technological parameters for the optimal operation of installations with the specified bed are obtained in relation to solving the problem of cooling the circulating water. The dependence of the expansion of a three-phase fluidized bed on air velocity and irrigation density has been investigated. On the basis of the performed experimental studies, empirical formulas for calculations are derived.

Highlights

In the Republic of Uzbekistan, one of the main areas of the economy is currently receiving a lot of attention: the development of technological equipment for the energy industry that meets modern standards, such as the modernization of cooling systems for circulating water and air conditioning [1, 2]
The 2017–2021 Strategy of Actions for the Further Development of the Republic of Uzbekistan emphasized the necessity of reducing the economy's energy and resource intensity through widespread use of energy-saving technologies [3,4,5,6]
A numerical method that takes into account any changes in the parameters of the cooled water, the environment, design, thermal engineering, and operational characteristics of individual elements and units of the cooler is another

Summary

Introduction

In the Republic of Uzbekistan, one of the main areas of the economy is currently receiving a lot of attention: the development of technological equipment for the energy industry that meets modern standards, such as the modernization of cooling systems for circulating water and air conditioning [1, 2]. This method allows for more reliable initial data to be obtained and substantiated for the development of appropriate engineering solutions to ensure the efficient operation of coolers of this type in various branches of the energy, processing, petrochemical, and food industries at the current stage of computer technology development. Making a part of the body in the form of a diffuser, organizing a higher degree of water dispersion, installing centrifugal nozzles, changing the design of sprinklers All these measures give an additional increase of water cooling by another [11]
