Abstract

An air-type ash and coke removing device with common frequency interference shockwave is characterized by delivering the interference shockwave into a variety of furnace and electric precipitation, to clean the ash deposition and coke. A speed regulation motor drives a disc between an outer wall of an air chamber and a buckle closure, the disc is opened with 4-18 holes with different shaft from the disc, and the disc is attached to the 4-18 groups of outlets of contracting nozzles and inlets of diffusion nozzles. The contracting nozzle and the diffusion nozzle are uniformly distributed using shaft line of the transmission shaft as a center of circle, and are fixed on the inner wall of the air chamber and the buckle closure. The disc opens and closes the 4-18 Laval nozzles periodically to make the outlet area of each group of contracting nozzles and the inlet area of the diffusion nozzles change periodically, so as to obtain 4-18 groups of shockwaves at the front ends of the 4-18 diffusion nozzles, and then the group of shockwaves interfere and superimpose at the intersection of the diffusion nozzles to generate stronger interference shockwave. The invention can be used in the fields of electric power, chemical engineering, metallurgy, and building material, and has good ash removing effect.

Description

Air type is with frequently interfering shock wave ash-cleaning and coke-removing device

Technical field

This device belongs to dynamo-electric field, adopts mechanical means to produce with frequently interfering shock wave, is used to remove dust stratification, the coking of various types of boilers, heat exchanger, electric cleaner, hopper etc.

Background technology

In the prior art, remove the method for dust stratification coking,, with frequently interfering the shock wave ash disposal to defocus,, shortcoming arranged though very strong practicality is arranged like 201020130172.8 descriptions of Chinese patent: the shock strength that two groups of shock waves are interfered generations relatively a little less than.

Summary of the invention

The purpose of this device is with instantaneous outflow four--the same frequency homophase same direction jet of-ten eight shrink nozzles; When flowing through diffusion jet pipe front end respectively; Acceleration is four---ten eight groups of speed is greater than the pulse shock wave of mach one, and interferes stack in diffuser pipe intersection, generates stronger interference shock wave relatively.

The utility model solves the technical scheme that its technical problem adopted:

Buncher 1 drives through power transmission shaft 9 and places air chamber wall 7 outer walls and buckle closure 6 middle disks 4 to rotate; Have on the disk 4 and its out-of-alignment four---ten eight holes; Disk 4 is close to four--and-ten eight groups of shrink nozzle 8 outlets enter the mouth with diffusion jet pipe 5;-ten eight diffusion jet pipes 5 of four---ten eight shrink nozzles 8 are that the center of circle evenly distributes and is fixed on air chamber wall 7 inwalls four with power transmission shaft 9 axis--are that the center of circle evenly distributes and is fixed on the buckle closure 6 with power transmission shaft 9 axis, and shrink nozzle 8 outlets enter the mouth coaxial with diffusion jet pipe 5; Four---ten eight diffusion jet pipe 5 pipes cross along the motor transmission shaft axis direction; Shrink nozzle 8 is an injection well, and diffusion jet pipe 5 is an air vent, and disk 4 rotations make four---ten eight Laval nozzles periodically open and close simultaneously; Air chamber 2 also has air inlet 3, it is characterized in that this four---ten eight Laval nozzles can make the gas of flowing through quicken to be converted into high-power with frequently interfering shock wave.

The beneficial effect of the utility model:

Because this device adopts four---ten eight diffusion jet pipes, and-ten eight groups of shock waves generations of four---ten eight diffusion jet pipes cross along the motor transmission shaft axis direction, make four--interference stack form and interfere shock wave.This shock strength is big, and the ash-cleaning and coke-removing effect is remarkable, can effectively improve the boiler heat exchange efficiency, or effectively improves the electric cleaner efficiency of dust collection.This device can be widely used in fields such as electric power, metallurgy, petrochemical industry, building materials.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Accompanying drawing is the structural representation of embodiment.

Among the figure 1, buncher 2, air chamber 3, air inlet 4, disk 5, diffusion jet pipe 6, buckle closure 7, air chamber wall 8, shrink nozzle 9, power transmission shaft

Specific embodiments

Four--8 outlets of-ten eight shrink nozzles are fixing with the welding of air chamber wall 7 inwalls, and are that the center of circle evenly distributes with power transmission shaft 9 axis.Four---ten eight diffusion jet pipe 5 inlets are fixing with buckle closure 6 welding, and diffusion jet pipe 5 inlets are with four--and-ten eight shrink nozzle 8 outlets are coaxial respectively.Disk 4 places in the middle of air chamber wall 7 outer walls and the buckle closure 6, and both Laval nozzle throat connected with power transmission shaft 9, by buncher 1 driven in rotation.Institute's working medium can be air, nitrogen.
