Flameless flash explosion soot blower

Abstract

The invention relates to a boiler soot blower, in particular to a flameless flash explosion soot blower widely used in the operation process of a power station boiler and a garbage incinerator. The flameless flash explosion soot blower mainly comprises a high-pressure generation loop and a gas flash explosion loop. The flameless flash explosion soot blower is mainly and technically characterized in that low-pressure compressed air is pressurized again by adopting liquid or non-pressure air is pressurized in a full-parameter mode, flameless flash explosion and ultrahigh-pressure operation are achieved, the potential safety hazards of flammability and explosiveness are eliminated, and a powerful guarantee is provided for improving electric power safety production.

Description

technical field [0001] The invention relates to a boiler flue soot blowing device, in particular to a flameless flash soot blowing device which is widely used in the operation process of boilers of various levels and types, especially power plant boilers. Background technique [0002] The soot blowing devices currently on the market or installed in a large number of boiler tail flues generally use steam continuous soot blowing devices, sonic wave soot blowing devices, and shock wave soot blowing devices. Steam soot blowing devices contain a large amount of water vapor because the blowing medium contains a large amount of water vapor. , easy to stick ash, and lead to a large increase in smoke exhaust and increase in boiler heat loss; the sonic soot blowing device uses low-pressure compressed air to generate mechanical vibration energy to hit floating ash. Due to the low pressure, the soot blowing effect is unsatisfactory; The wave soot blower adopts the pressure wave generate...

Problems solved by technology

[0002] The soot blowing devices currently on the market or installed in a large number of boiler tail flues generally use steam continuous soot blowing devices, sonic wave soot blowing devices, and shock wave soot blowing devices. Steam soot blowing devices contain a large amount of water vapor because the blowing medium contains a large amount of water vapor. , easy to stick ash, and lead to a large increase in smoke exhaust and increase in boiler heat loss; the sonic soot blowing device uses low-pressure compressed air to generate mechanical vibration energy to hit floating ash. Due to the low pressure, the soot blowing effect is unsatisfactory; The wave soot blower adopts the pressure wave generated by the deflagration of combustible gas, its pressure reaches 0.1 MPa, and the soot blowing effect reaches the expectation. Flammable and explosive gases, usually hydrogen, acetylene, methane, coal gas, liquefied petroleum gas, etc., these bottled flammable gases are stored near the boiler for a long time, which is really a great safety hazard. Therefore, it is necessary to carry out technical upgrading or product replacement

[0003] The two fundamental problems to be solved by the soot blowing device are: one is the pressure of the blowing medium; the other is the problem of safe detonation
