Abstract
The utility model relates to dust removal equipment, in particular to a spiral channel dust collector. The spiral channel dust collector comprises an air inlet, a separation main body, a dust collection hopper and an air outlet, wherein the separation main body is arranged at the middle part of the dust collector, the air outlet is arranged at the upper part, and the dust collection hopper is arranged at the lower part; a spiral channel is arranged in the separation main body; and a porous isolation plate is fixedly connected in the spiral channel through a partition plate. The spiral flow can lengthen the dust collection path and increase the centrifugal force; without a gas flow channel in a gas-solid isolation area, the gas is static, thus two or more times of mixing of the dust particles and the gas flow can be avoided; the distance for the dust particles to reach the gas-solid isolation area is shortened in a multi-channel mode so as to improve the dust collection efficiency; the spiral flow horizontally moves to the central area and moves upward to the air outlet, thus the moving path of the gas flow is simpler, and the resistance loss is reduced; and the dust collector is low, and when in use, the technology is relatively simple.
Description
Technical field
The utility model relates to a kind of cleaner, particularly a kind of helical duct dust-precipitator.
Background technology
Traditional cyclone type dust-precipitator is that the air-flow that carries dust is tangentially got into spiral case, and in rotary course, dust loses speed after receiving centrifugal action to run into inner walls; Lean on the gravity effect to descend and fall into flue-dust retainer; Air communication is crossed the bottom-up motion of inner core, and the realization dust separates with gas, but owing to do not have tangible interface between the dust granules of air-flow and sedimentation; Dust also can be forced to take part by air-flow again, thereby reduces dust-collecting efficiency.Particularly large-scale dust-precipitator, the distance near the dust granules at center and inner walls in rotary course is big, can not arrive inner walls, thereby dust can not get separating with gas; Air-flow is accomplished the rotation back and is moved upward by moving downward to transfer to, can cause bigger drag losses, so energy consumption is higher.
Summary of the invention
The utility model is to deficiency of the prior art, and a kind of employing helical baffle gas solid separation is provided, and dust-collecting efficiency is high, energy consumption is low, the simple relatively helical duct dust-precipitator of technology arrangement when using.
Realize that the technical scheme that above-mentioned purpose adopts is:
A kind of helical duct dust-precipitator; Comprise: air inlet, separation main body, flue-dust retainer, air outlet; Said dust-precipitator middle part is provided with the separation main body, and its top is provided with air outlet, and its underpart is provided with flue-dust retainer; Be provided with helical duct in this separation main body, this helical duct inside is connected with the porous division board through dividing plate.
Compared with prior art, the beneficial effect of the utility model is: spiral flow can make the path of gathering dust longer, and centrifugal action is bigger; Do not have gas channel in the gas-solid isolated area, gas is static, can avoid dust granules with the secondary of air-flow even repeatedly mix; Much channel communication makes dust granules arrive the reduced distances of gas-solid isolated area, thereby improves dust-collecting efficiency; Move upward behind the spiral flow horizontal movement arrival central area and be air outlet, the air motion route is simpler, thereby reduces drag losses; The dust-precipitator height is little, and technology arrangement is simple relatively during application.

Fig. 5 is the utility model porous partition plate structure sketch map.
Among the figure: air inlet 1, separate main body 2, porous division board 3, helical duct 4, gas-solid isolated area 5, flue-dust retainer 6, air outlet 7, split-wind plate 8, dividing plate 9 is crossed dirt hole 10.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
A kind of helical duct dust-precipitator; Comprise: air inlet 1, separation main body 2, flue-dust retainer 6, air outlet 7; Said dust-precipitator middle part is provided with separates main body 2, and its top is provided with air outlet 7, and its underpart is provided with flue-dust retainer 6; Be provided with helical duct 4 in this separation main body 2, these helical duct 4 inside are connected with porous division board 3 through dividing plate 9.
As a kind of preferred version of the utility model, said helical duct 4 is a single channel.
As a kind of preferred version of the utility model, said helical duct 4 is a multichannel, and this helical duct 4 air inlets 1 place is provided with split-wind plate 8.
As a kind of preferred version of the utility model, said porous division board 3 is shape in the shape of a spiral, evenly is provided with dirt hole 10 on its plate face.
The operation principle of the utility model is summarized as follows:
This helical duct dust-precipitator adopts single channel and multichannel according to actual operating conditions.
2 liang of channel modes of embodiment are seen Fig. 3, and after dust-contained airflow got into from air inlet 1, import split-wind plate 8 was divided into two parts with air-flow, and a part gets into outer shroud helical duct 4, ring helical duct 4 in a part gets into.The air-flow of inner and outer ring helical duct 4 is all pressed spiral of Archimedes direction motion, dust receive centrifugal action outwards motion pass porous division board 3 cross dirt hole 10, get into gas-solid isolated area 5; Dust granules loses speed after running into separation main body 2 inwalls; Lean on the gravity effect to descend and fall into flue-dust retainer 6, the two passage air-flows that arrive after the central area purifies move upward, and a part is mixed; A part gets into air outlet 7 respectively, realizes the high efficiency separation of dust and gas.
