Abstract
The invention relates to an electric-bag composite dust removal smoke distribution device which is applicable to a traditional electrostatic dust collector and an existing electric-bag composite-type smoke distribution process. According to the technical scheme, the smoke distribution device in an electric dust removal air inlet hood comprises a dust collector, wherein an ash bucket opening insertion plate and a flap valve are arranged below the dust collector, and the smoke distribution device is characterized by also comprising an air inlet distribution main pipe, a plurality of distribution plates and a manual air inlet adjusting valve, wherein the manual air inlet adjusting valve is installed on the air inlet distribution main pipe. The air speed in a pipeline at each smoke flow route of the dust collector is optimized in a segmentation manner, the air admission of the dust collector adopts an air distribution system and adequately utilizes the natural distribution principle of the air, so that the uniformity and smoothness in air admission of the unit can be guaranteed, and the utilization rate of a filter area can be increased.
Description
Technical field
The present invention relates to a set of electric bag composite dedusting flue gas shunting device, be applicable to old-fashioned electrostatic precipitator and existing electric bag combined flue gas shunting technique.
Background technology
In electrostatic precipitator, air flow method is one of principal element affecting its de-dirt efficiency.For improving the efficiency of dust collection of electrostatic precipitator, the mode that Chinese scholars and engineer utilize experiment and computation machine to simulate has carried out large quantifier elimination to the air flow method how regulated in deduster.No matter be the uniform air flow method mentioned in early days, the skewed gas flow still mentioned in recent years is theoretical, is all referred to the method using porous plate to regulate air-flow in electrostatic precipitator.But for some electrostatic precipitator and designing requirement thereof, simple use orifice plate carries out regulating air-flow cannot meet the air flow method index of design side's proposition.
Summary of the invention
In view of the technical deficiency that existing old electrostatic precipitator exists, flue gas shunting device in electric precipitation airscoop shroud of the present invention
,flow of flue gas in reasonable distribution deduster, solves air flow method inequality, and dust removing effects is bad and put the not thorough difficult problem of ash.
For achieving the above object, this patent this patent adopts and technical scheme: flue gas shunting device in a kind of electric precipitation airscoop shroud, comprise deduster, deduster has grey quarrel plate and flap valve, it is characterized in that, also comprise air intake shunting house steward, multiple flow distribution plate, air inlet manual modulation valve, air inlet manual modulation valve is arranged on air intake shunting house steward;
Described air intake shunting house steward entirety is inserted in deduster, air intake shunts the flue gas shunting mouth that total tube end establishes multiple tandem to arrange in deduster inner underside face, the stepped rising of multiple flue gas shunting open heights, described flow distribution plate is obtuse angle V-type plate, flow distribution plate to be arranged on above flue gas shunting mouth and corresponding with flue gas shunting mouth number, and V-type level is while towards flue gas shunting mouth.
According to flue gas shunting device in described electric precipitation airscoop shroud, it is characterized in that, described flue gas shunting adopts the one in electrostatic precipitator, electric bag compound type dust remover.
According to flue gas shunting device in described electric precipitation airscoop shroud, it is characterized in that, described flue gas shunting mouth is funnel-form.
Dusty gas in this device is when by flue gas shunting device, due to the unexpected decline of wind speed, big dust particle generation natural subsidence in dusty gas also, directly fall into ash bucket, the guiding of all the other dust at separate system after separate system is separated under, enters casing filtering area with air-flow.
By above transformation, air velocity duct in each flue gas flowing through channel of deduster has carried out section optimal design, the air intake of deduster have employed gas distribution system and takes full advantage of the natural distribution principle of gas, ensure that the even and suitable of unit air intake, to improve filter area utilization rate.
Dusty gas enters each unit filter chamber by isocon, owing to having enough reasonably headroom from air inlet vertical range suitable for reading at the bottom of bag in design, air-flow is by after shunting, rely on resistance NATURAL DISTRIBUTION, reach being evenly distributed of whole filtration indoor air flow and each space resistance, ensure rational plume rise speed, reduce turbulent flow to greatest extent, prevent reentrainment of dust.
Accompanying drawing explanation
Fig. 1 is electric cleaner flue gas shunting device schematic diagram of the present invention;
Reference numeral: 1, deduster; 2, grey quarrel plate; 3, flap valve; 4, air intake shunting house steward; 5, flue gas shunting mouth; 6, flow distribution plate.
Detailed description of the invention
Below in conjunction with accompanying drawing and instantiation, the present invention is further illustrated:
Here V-type flow distribution plate is used to regulate the air-flow in electrostatic precipitator airflow inlet cover in conjunction with orifice plate, in order to reach the object optimizing accumulation area air flow method.Three-dimensional air flow method situation in electrostatic precipitator is calculated by using the method for numerical simulation, compared for electrostatic precipitator project to be used alone porous plate and to regulate the distribution of air-flow and use porous plate to combine with V-type splitter to regulate the method for air-flow, V-type splitter is proposed in the advantage regulating electrostatic precipitator air-flow.
This device comprises air intake shunting house steward, flow distribution plate, air inlet manual modulation valve.The effect of deduster smoke inlet place flow distribution plate is dispersion porch flue gas, avoid occurring that flue gas is concentrated in intermediate distribution, in the phenomenon that both sides distribution is rare, the effect of flow distribution plate avoids porch flue gas directly to wash away cloth bag, cause porch cloth bag overload and the phenomenon that other position cloth bag loads kick the beam, make velocity of flue gas field even.Flue gas enters from porch, descending along flow distribution plate, and at dust collector ash hopper, place overturns from bottom to top along ash bucket, and part flue dust contacts after bottom cloth bag and is captured, and part flue dust is up with air-flow in cloth bag gap, is adsorbed at the differing heights of cloth bag.In porch, there is higher speed, after arriving dirt pocket, along with air dispersion speed declines.Flue dust is dispersed in whole dirt pocket space, makes the filter effect of cloth bag reach best.
Embodiment recited above is only be described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; under the prerequisite not departing from design concept of the present invention; the various distortion that in this area, common engineers and technicians make technical solution of the present invention and improvement, all should fall into protection scope of the present invention.
