Abstract
A liquid pulse detonation ash remover includes an explosion blast chamber and a bow-wave transmission tube. One end of the explosion blast chamber is connected with an air intake tube and a fuel nozzle and the other end of it is connected with the bow-wave transmission tube. The fuel nozzle is equipped on the end of the air intake tube and it is concentrically provided with the air intake tube. The inner wall of the explosion blast chamber is equipped downstream the fuel nozzle with an igniter and a blast chamber disturbance flow reinforcing apparatus is equipped downstream the igniter closely cooperating with the inner wall of the blast chamber. Because the explosion blast chamber is connected with the air intake tube and the fuel nozzle, the liquid fuel can be used to burn to produce pinking. And as a conventional fuel, the liquid fuel has the advantages of convenient storage, small volume, high caloricity, easy ignition, etc. Accordingly, the bow-wave blower is more safe and reliable, and the application range is wider.
Description
Technical field
The utility model relates to a kind of boiler ash-cleaning and coke-removing equipment.
Background technology
For solving the ash disposal problem of boiler, the different various soot blowers of operation principle have been developed both at home and abroad, the patent No. as the applicant is the patent of ZL00209277.8, and this patent had obtained to use preferably in recent years, can remove the knot ash of various heat exchanger surfaces preferably.But the fuel that this device adopts is acetylene gas, acetylene gas is a gas inflammable, that explosion hazard is very strong, placing acetylene gas bottle on the boiler limit of operation power plant is complete abuse, under the prerequisite that does not have other better soot blower to occur, can only improve security requirement, and acetylene gas is just in case reveal the danger that will cause blast; And tempering also takes place in this soot blower easily, also can work the mischief to the security of equipment.These weak points have limited the application of this dust remover greatly.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of safe and reliable, application surface liquid pulse pinking more widely dust remover.
For achieving the above object, technical solution of the present utility model is:
A kind of liquid pulse pinking dust remover, comprise explosive combustion chamber, shock wave transmitting tube, described explosive combustion chamber one end is connected with air intake duct and fuel nozzle, the other end connects the shock wave transmitting tube, this fuel nozzle is arranged at the air intake duct end and is provided with this air intake duct is concentric, be provided with igniter in this fuel nozzle downstream on the described explosive combustion chamber interior walls, closely cooperating in this igniter downstream and this explosive combustion chamber interior walls is provided with combustion chamber turbulent flow intensifier.
Further, between described air intake duct and fuel nozzle, be provided with the air inlet flow spoiler, this air inlet flow spoiler comprises the two inside and outside annular plates that are provided with one heart, be connected to the dividing plate that same direction tilts by several between this two annular plate, described fuel nozzle is arranged at interior annular plate center.
Further, described air intake duct comprises vertical tube and the horizontal tube that is interconnected, and this vertical tube, the equal both ends open of horizontal tube, this horizontal tube are a conical pipe along the airintake direction flaring, and described fuel nozzle is concentric and be located at this conical pipe end with this conical pipe.
Further, between the horizontal tube of described air intake duct and fuel nozzle, be provided with the air inlet flow spoiler, this air inlet flow spoiler comprises the two inside and outside annular plates that are provided with one heart, be connected to the dividing plate that same direction tilts by several between this two annular plate, described fuel nozzle is arranged at interior annular plate center.
Further, described combustion chamber turbulent flow intensifier is the annular plate of perforate in the middle of.In interior annular plate center.
After adopting said structure, because the explosive combustion chamber is connected with air intake duct and fuel nozzle, therefore can utilize liquid fuel combustion to produce pinking, and liquid fuel is as a kind of conventional fuel, have and be convenient to storage, advantages such as volume is less, calorific value is high, easy igniting, therefore make the shock-wave ash blowing device safer, reliable, application surface is more extensive; In addition,, therefore strengthened air agitation, and can prevent effectively that the indoor burning gases of explosive combustion from flowing backwards and tempering owing between this air intake duct and fuel nozzle, be provided with the air inlet flow spoiler; Air intake duct comprises vertical tube and the horizontal tube that is interconnected, make air from vertical tube up and down two inlets enter, air-flow more steadily, evenly, make oil inflame more abundant, and horizontal tube is a conical pipe along the airintake direction flaring, has prevented that further the indoor burning gases of explosive combustion from flowing backwards.
