Modeling simulation method of condenser ultrasonic cleaner

Abstract

The invention discloses a modeling and simulation method of a condenser ultrasonic cleaner, which comprises the following steps of: constructing a series of parameterized models of condensers with different ultrasonic inlet modes according to specific condenser structure parameters, and simulating the action of the ultrasonic cleaner by using an ultrasonic sound pressure function; according to themethod, the action effect of the ultrasonic scaler on the flow field in the condenser can be simulated more accurately, that is, a Solidworks Fluent joint simulation method is utilized to compile programs of ultrasonic sound pressure functions, parameterized models of the condensers are combined with different ultrasonic sound pressures, and by comparing different ultrasonic inlet modes with different ultrasonic sound pressure function combinations, the effect of the ultrasonic scaler on the flow field in the condensers can be simulated. The influence of various factors such as the number, the power, the power dispersity, the frequency combination and the arrangement position of the ultrasonic scale removers on the ultrasonic scale removal effect of the condenser is reduced, and parameteroptimization suggestions are provided for the installation of the scale removers of the N20910 type condenser.

Description

technical field [0001] The invention relates to the field of ultrasonic descaling, in particular to a modeling simulation method of an ultrasonic descaling device for a condenser. Background technique [0002] With the rapid development of industrialization and modernization, human's demand and consumption of energy are increasing day by day, and the shortage of fossil energy is becoming more and more serious. my country vigorously advocates an energy-saving economy and sustainable development, and energy conservation and emission reduction has become one of the important indicators for examining the operation of enterprises. The electric power industry plays a very critical role in the energy industry, and condensing equipment is a very important heat exchange equipment for thermal power generating units. [0003] Research results have shown that more than 90% of heat exchange equipment has fouling problems of varying degrees. After the cooling tube of the condenser is fo...

Problems solved by technology

The disadvantage of high-pressure water jet cleaning is that starting and stopping consumes a lot of labor and time, resulting in high costs, especially for large units with basic loads, it is impossible to stop cleaning frequently

The problem of rubber ball cleaning is that the cleaning is not thorough. Chemical cleaning is usually acid cleaning. The disadvantage is that the acidic reagent will corrode the copper tube of the condenser.

The electrostatic water treatment method is widely used in industrial water treatment in industrialized countries such as the United States and Japan, and the domestic technology of using electrostatic method to descale the condenser is not yet mature.
