Abstract
The invention discloses an air intake distributor of a pulse back flushing bag filter. The air intake distributor comprises a distributing ring bracing frame connected with an air-supply pipe and several grades of distributing rings; the air-supply pipe is fixedly connected with the distributing ring bracing frame; the bracing frame comprises a plurality of skeletons in taper arrangement; a diameter of the distributing ring bracing frame is lessened from the air-supply pipe to an outlet of the air intake distributor; the distributing rings are circular ring sheets equipped with central through holes; sizes of the distributing rings are decreased step by step; and the distributing ring is fixed on the distributing ring bracing frame at a certain angle. The air intake distributor of the pulse back flushing bag filter of the invention realizes more uniform air-flow distribution and facilitates working efficiency increase of the pulse back flushing bag filter.
Description
Technical field
The present invention relates to a kind of flow distributor, particularly a kind of air intake distributor for the pulse backblowing bag hose.
Background technology
In the prior art, utilize the pulse backblowing bag hose can carry out the collection of carbon powder, the blast pipe place input of pulse backblowing bag hose contains the air-flow of carbon powder, after this air-flow blows to filter bag, gas can see through filter bag, discharge from air outlet, and carbon powder can be stayed on the filter bag, in the carbon powder collection process, the even diffusion of air-flow and the collection efficiency that flows for carbon powder have bigger influence, air-flow spreads when even, and all filter bags can both effectively filter carbon black, when air-flow spreads when inhomogeneous, local air flow density is big, can cause the accumulation of carbon black on indivedual filter bags, influence the service life of filter bag, the filter bag in the place that current density is low then efficient can be very low.Very big from the current rate of air inlet input, in order to prevent that the filter bag in the air-flow paired pulses blowback bag hose from impacting, simultaneously for air-flow being played the effect of diffusion, a deep bead that is used for changing wind direction will be set at the blast pipe place usually, the air-flow that enters from blast pipe has changed original direction of advance under the effect of deep bead, diffuse to all directions in the pulse backblowing bag hose, but this set has concentrated on the face at deep bead place the guiding of air-flow, be unfavorable for the rapidly and uniformly diffusion of air-flow in the pulse backblowing bag hose, will inevitably reduce the collection efficiency of carbon powder.
Summary of the invention
The objective of the invention is to be unfavorable for the rapidly and uniformly diffusion of air-flow in the pulse backblowing bag hose at what the deep bead in the air intake distributor of the existing pulse backblowing bag hose described in the background technology existed, will inevitably reduce the problem of the collection efficiency of carbon powder, a kind of air intake distributor of pulse backblowing bag hose is provided.
The technical scheme that can realize goal of the invention of the present invention is as follows:
A kind of air intake distributor of pulse backblowing bag hose, it comprises distribution ring bracing frame and the some grades of distribution rings that are connected with blast pipe, described blast pipe is fixedlyed connected with distributing the ring bracing frame, described distribution ring bracing frame comprises several skeletons, the tapered setting of each skeleton, air outlet from from blast pipe to the air intake distributor distributes the diameter of ring bracing frame to dwindle gradually, described distribution ring is the circular ring plate that is provided with central through hole, distribute the size of the central through hole of ring to successively decrease step by step, distribute ring to be fixed at an angle and distribute on the ring bracing frame.
In order to adjust the direction of distribution of air flow, air-flow can be spread at the pulse backblowing bag hose rapidly and uniformly, when air intake distributor horizontal positioned, the angle of described distribution ring and vertical direction is 28 °～35 °.
Average for the amount that makes distribution of air flow at different levels, the inner ring of described distribution ring and the ring width between the outer ring are fixed.
Further, the inner ring of described distribution ring and the ring width between the outer ring are 3cm-7cm.
In order to ensure distributing ring and distributing firm connection between the ring bracing frame, described distribution ring is fixedly connected by welding with distributing the ring bracing frame.
For the ease of distributing the assembling of ring, described distribution ring is metal material, and it comprises a plurality of arc sections, is welded to connect between each arc section.
Beneficial effect of the present invention is provided with the distribution ring bracing frame that is connected with blast pipe for the air intake distributor because of pulse backblowing bag hose of the present invention, some levels are arranged at the distribution ring that distributes in the ring bracing frame at an angle, when air-flow enters the air intake distributor from blast pipe, when running into first order distribution ring, part air-flow dispersal direction under the effect of first order distribution ring changes, part air-flow passes the central through hole that distributes ring, a part of air-flow in addition is when arriving the anchor ring that distributes ring, be subjected to the effect of the resistance of anchor ring, because described distribution ring bracing frame comprises several skeletons, therefore distribute the ring bracing frame can not hinder the diffusion of air-flow, air-flow can along distribute towards the first order ring place towards diffusion on every side, in like manner, when entering follow-up distribution ring at different levels, because the diameter of the central through hole of the distribution ring of back successively decreases step by step, therefore, can carry out step by step distribution to air-flow, the air-flow that blast pipe is entered distributes fast and diffuses in the pulse backblowing bag hose.Pass through this set, make that the distribution of air-flow is more even, be conducive to improve the operating efficiency of pulse backblowing bag hose, simultaneously, also avoid local air flow bigger, occurred the accumulation of carbon powder on the filter bag, prolonged the service life of filter bag, and improved the service efficiency of filter bag, and then improved the collection efficiency of carbon powder, carbon black collection efficiency and the performance of pulse backblowing bag hose are significantly promoted.
