Abstract
Rotary regenerative air heater is related to a kind of sound wave ash cleaner to rotary regenerative air heater deashing with sound wave ash cleaner.Mainly designed to solve the problems such as being not thorough currently with the dust stratification that steam soot-blower is cleared up on air preheater heat exchange element.It includes one section of public address cylinder, and by flanged joint, the front end and three sections of public address cylinder of rear end that two sections of public address cylinder pass through flanged joint for the front end that one section of public address cylinder and two sections of public address cylinder of rear end；The front end that three sections of public address cylinder passes through flanged joint with pipeline section is connect, and connecting on pipeline section has electrically operated valve, and the front end for connecting pipeline section is connect with diaphragm type acoustical generator, and air inlet pipe is connected on diaphragm type acoustical generator, there is solenoid valve, filtering pressure regulator valve, ball valve in air inlet pipe；The rear end that one section of public address cylinder is connected with amplifier；The lower end of amplifier is equipped with air jet pipe, and air jet pipe is equipped with several nozzles, and the front end of air jet pipe is connected with accumulator, and the inlet end of accumulator has pulse valve.Advantage is that ash disposal is thorough.
Description
Technical field:
The utility model relates to a kind of sound wave ash cleaners to rotary regenerative air heater deashing.
Background technique:
The rotary regenerative air heater dust stratification of heat exchange element meeting in use for some time, such as deashing will lead to exhaust gas temperature not in time
It increases, reduces Boiler Economical Operation, and reduce the service life of air preheater.
Be currently using steam soot-blower cleaning heat exchange element on dust stratification, but its there are the following problems:
One, steam drainage cannot be emptied thoroughly, and moist steam, which enters, can aggravate stifled ash.
Two, boiler sootblowing steam consumption is big, and operating cost is high.
Three, steam soot-blower installation is complicated, and occupied space position is big.
Four, high fume temperature.
Summary of the invention:
The technical problem to be solved by the utility model is to provide a kind of soot blowing effect is good, energy consumption is few, and no metal fatigue can
Extend the rotary regenerative air heater sound wave ash cleaner of air preheater service life.
Above-mentioned purpose is achieved in that it includes one section of public address cylinder, the front end that one section of public address cylinder with two sections of public address cylinder
By flanged joint, the front end and three sections of public address cylinder of rear end that two sections of public address cylinder pass through flanged joint for rear end；
The front end that three sections of public address cylinder passes through flanged joint with pipeline section is connect, and connection pipeline section is equipped with electrically operated valve, connecting tube
The front end of section is connect with diaphragm type acoustical generator, and air inlet pipe is connected on diaphragm type acoustical generator, has solenoid valve, filtering to adjust in air inlet pipe
Pressure valve, ball valve；
The rear end that one section of public address cylinder is connected with horn-like amplifier；The lower end of amplifier is equipped with air jet pipe, on air jet pipe
Equipped with several nozzles, the front end of air jet pipe is connected with accumulator, and the inlet end of accumulator is equipped with pulse valve.
Electrically operated valve, solenoid valve, filtering pressure regulator valve, pulse valve have conducting wire to be connected with the PLC in electric cabinet.
The utility model has the advantages that: in use, the present apparatus is mounted on Clothoid type air preheater, make the lower end of amplifier
It is aligned above the heat exchange element of Clothoid type air preheater.Compressed air enters diaphragm type acoustical generator after filtering pressure regulator valve pressure regulation
It is interior, low-frequency sound wave is generated through the resonance of three sections, two sections, one section generations of public address cylinder, cumulative harmony is amplified by amplifier, act on and change
On the dust stratification layer of pyrogen part.Compressed steam in accumulator is sprayed through nozzle, using its moment Blasting shock wave by dust stratification into one
Step is cleaned out.Its in sound wave effective range, coordinating with steam rapid heat cycle soot blowing can thorough ash disposal, no dead angle ensure that heat exchange
The cleaning of element effectively improves heat exchange efficiency, reduces exhaust gas temperature.Since it is non-contact deashing, no metal fatigue, so prolonging
The long heat exchange element service life.In addition it is also energy saving.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
Referring to Fig.1, it includes one section 1 of public address cylinder, and the front end that one section of public address cylinder and two section 2 of public address cylinder of rear end pass through flange
Connection, the front end and three section 3 of public address cylinder of rear end that two sections of public address cylinder pass through flanged joint；
The front end that three sections of public address cylinder passes through flanged joint with pipeline section 4 is connect, and connection pipeline section is equipped with electrically operated valve 5, connection
The front end of pipeline section is connect with diaphragm type acoustical generator 6, and air inlet pipe 7 is connected on diaphragm type acoustical generator, have in air inlet pipe solenoid valve 8,
Filter pressure regulator valve 9, ball valve 10；
The rear end that one section of public address cylinder is connected with horn-like amplifier 11；The lower end of amplifier is equipped with air jet pipe 12, jet
Pipe is equipped with several nozzles 13, and the front end of air jet pipe is connected with accumulator 14, and the inlet end of accumulator is equipped with pulse valve 15.
Electrically operated valve, solenoid valve, filtering pressure regulator valve, pulse valve have conducting wire to be connected with the PLC in electric cabinet 16.
