Description
Technical field
The present invention relates to a kind of pulse dust collector belongs to dust removal by ventilation field with ash cleaning jet nozzle is pressed.
Background technology
As the development of social economy, atmosphere pollution are increasingly serious, protect, administer, improving atmosphere polluting problem and obtain
The common recognition of the whole mankind.In order to adapt to the needs of Environmental Protection Cause, dedusting industry also further developed new technology, new material,
New technology, new product, deduster have become one of capital equipment of control atmosphere pollution.Different, the dedusting according to the property of power
Device is often divided into electric cleaner, sack cleaner, cyclone dust collectors, wet scrubber.The deduster of other patterns is compared, pocket type is removed
Dirt device is high due to its purification efficiency, ash-removal effect is good, maintenance workload is little, safe and reliable to operation the advantages of be widely used.Bag
The purge mode of formula deduster has gas pulses, mechanical vibrator, rotary counter-blowing, and wherein gas pulses dedusting method is a kind of conventional
Purge mode.Ash-clearing technology is always the decisive factor and key technology of performance of precipitator, and is to limit its bottleneck for developing.
Ash-removal effect is related to the indices such as the economic benefit of resistance, efficiency, consumptive material service life and deduster operation of deduster.
Ash-removal effect is good, can guarantee that pulse dust collector operation steady in a long-term under low pressure loss；Ash-removal effect is bad, will cause to filter
The dust accumulation on material surface is uneven, and filter bag or cartridge sidewall pressure peak are uneven, and air pulse action time is inconsistent, removes
The resistance of dirt system gradually increases, and seriously causes the misoperation of pulse filter cylinder dust pelletizing system；In addition, the deashing of filter bag or filter cylinder
The uneven dust-contained airflow VELOCITY DISTRIBUTION that will result in is uneven, and excessively denuding occurs in subregion, and affects the use of filter bag or filter cylinder
Life-span.So, the quality of deashing is directly connected to the power of regeneration of filtrate.Chinese patent ZL2010520825373.2 is disclosed
A kind of sack cleaner drainage dispersion nozzles, carry out rectification using disperser to pulse spray dust and gas stream, make deashing air-flow more
Uniformly, dust removing effects are improved；United States Patent (USP) 6129852 discloses a kind of flow control member of filtering drum dust removing system, by cone
Shape structure enters filter cylinder after making air pulse diffusion, improves the ash-removal effect on filter cylinder top.The two design the deficiency for existing
Air pulse increases air pulse resistance after disperser or pyramidal structure, weakens the intensity that air-flow enters filter bag or filter cylinder,
It is not suitable for long filter bag or the long filter cylinder of heavy caliber.The present invention using drainage nozzles and accelerates diffuser to carry out pulse jet air-flow
Drainage induction, acceleration, diffusion, the flow for increasing pulse dust cleaning air-flow by drainage inducing peripheral gas, by accelerating increase arteries and veins
The intensity of deashing air-flow is rushed, by spreading increase air pulse and filter bag or the direct effect face of filter cylinder, and then it is equal to improve deashing
Evenness and its ash-removal effect, extend the service life of filtrate, can be according to specific filter bag or filter cylinder type selecting.
Content of the invention
In order to overcome the filtrate wall dust accumulation that filter bag or filter cylinder occur during pulse dust cleaning uneven, filter bag or
The deashing inequality problem such as filter cylinder axial direction lateral wall pressure peak action Time Inconsistency, peak value size disunity, the abrasion of filter cylinder part,
The present invention using drainage nozzles and accelerates diffuser to carry out drainage induction, acceleration, diffusion to pulse jet air-flow, is lured by drainage
The flow that ambient gas increase pulse dust cleaning air-flow is led, by accelerating the intensity of increase pulse dust cleaning air-flow, is increased by diffusion
Air pulse and filter bag or the direct effect face of filter cylinder, and then the deashing uniformity and its ash-removal effect is improved, extend making for filtrate
Use the life-span.The present invention is achieved through the following technical solutions：With ash cleaning jet nozzle is pressed, which includes that drainage is sprayed to a kind of pulse dust collector
Mouth, bar connection and acceleration diffuser.Described injection hole is located at the front end of drainage nozzles, and by bindiny mechanism and drainage nozzles
Closely connect；The described rear end for accelerating diffuser to be located at drainage nozzles, and connected by bar structure；Described injection hole and draw
The bindiny mechanism of flow nozzle is fixed welding, threaded connection, movable snap ring；Described acceleration diffuser is by internal accelerator, outer
Portion's diffuser and bottom current stabilization cylinder are constituted；The inside accelerator structure of described acceleration diffuser is shaped as venturi, gradually
The draw, supersonic speed pipe；The outer diffuser planform of described acceleration diffuser is frustum type, cone type；Described adds
The material of fast diffuser is solid material or porous material；The diffusion angle of the outer diffuser of described acceleration diffuser is
25°~75°.Beneficial effects of the present invention：Hydrodynamics is pressed theoretical and drainage theory to be applied in deashing by the present invention, normal
On the basis of rule injection hole pulse dust cleaning, install and accelerate diffuser that drainage acceleration induction diffusion, increase is carried out to pulse jet air-flow
The flow of pulse dust cleaning air-flow, while the entrance filter bag for making deashing air-flow more uniform and stable or filter cylinder, make filter bag or cartridge axis
Substantially uniform to lateral wall pressure peak action time consistency, peak value size, cartridge wall flour dirt accumulating amount is identical, clear so as to improve
The grey uniformity and its ash-removal effect, extend the service life of filtrate.
