Monitoring a chemical processing system by measuring the instantaneous sound transmission characteristics therein
Abstract
Abstract A CHEMICAL PROCESS IS MONITORED BY A SYSTEM FOR MEASURING THE INSTANTANEOUS SOUND TRANSMISSION CHARACTERISTIC IN A SUBSTANCE BEING PROCESSED. IN PROCESSES WHERE THE SUBSTANCE STRATIFIES, A PLURALITY OF MEASUREMENTS ARE MADE AT DIFFERENT STRATUMS OF THE MATERIAL WHILE IT IS BEING PROCESSED. THE SOUND TRANSMISSION CHARACTERISTICS ARE MEASURED BY A PLURALITY OF ELECTROACOUSTIC TRANSMITTING AND RECEIVING TRANSDUCER LOCATED WITHIN SEPARATE REGIONS OF THE MATERIAL BEING PROCESSED. A SOURCE OF ALTERNATING ELECTRIC POWER DRIVES THE TRANSMITTING TRANSDUCERS AND THE INTENSITY OF SOUND LEVEL PRODUCED IS PICKED UP BY THE RECEIVING TRANSDUCER WHICH RECORDS THE SOUND LEVEL THROUGH APPROPRIATE AMPLIFIERS AND INDICATORS. AS APPLIED TO WOOD CHIP DIGESTION, THE INSTANTANEOUS SOUNC TRANSMITTING CHARACTERISTICS INDICATE THE RATE AND PROCESS OF THE DIGESTION. D R A W I N G
