Nozzle for Injecting Sublimable Solid Particles Entrained in Gas for Cleaning Surface and Method for Cleaning Surface using the Nozzle

摘要

The invention comprises a that, the cleaning medium flowing from the cleaning medium source sublimate solid particles of the sublimable solid particles min using a nozzle that can prevent the frost caused by the cryogenic snow from the surface of the water nozzle and the object to be cleaned the cleaning medium to block the change in snow conditions that; A nozzle block for injecting the cleaning medium from the cleaning medium flowing snow block is grown by the adiabatic expansion to avoid cleaning the surface of the water; Carrier gas mixing block and the cleaning snow to the medium supplied to the nozzle block to the carrier gas flowing from the carrier gas source; And a configuration including at least a heater for heating a portion of the carrier gas supplied from carrier gas supply source. Also, after the present invention is an equipment configuration for supply is that the line that is, CO ₂ storage tank, dry ice particles that is created by the pressure of the flow control valve via a solenoid valve at a portion the liquid CO ₂ to the nozzle flows into the injection nozzle N ₂ carrier gas is mixed with air or purified form the structure being injected. The present invention is the injection of dry ice at the time the configuration automation equipment by mounting the additional thermocouple sensor at the outlet side end portion of the can automatically control the supply of the CO ₂ through the installation of the solenoid valve, and also blocks the carrier gas or the nozzle block nozzle you can confirm the presence or absence. ; Cleaning the nozzle, the venturi, adiabatic expansion, sublimation, solid particles, CO2, snow, the carrier
