Description
Technical field
The utility model belongs to cleaner field, and particularly, the utility model relates to a kind of dedusting sundries separator.
Background technology
Along with the development of science and technology, in dedusting ash conveying, pneumatic conveying process progressively instead of the technique that traditional humidifier unloads the outer row of ash, and pneumatic conveying process has without reentrainment of dust, does not consume water resource, and it is short to unload the grey time, the advantages such as labour intensity is low.The quality of application to dedusting ash of this new technology proposes higher standard, require do not have foreign material in dedusting ash, otherwise foreign material can block ash conveying pipe, affects the normal conveying of dedusting ash.
The foreign material that current deduster is separated in dedusting ash adopt separating sundries in two ways usually.First kind of way adds grid (as shown in Figure 1) in the dust excluding hood inside of each dust sucting point of deduster, the installation direction of grid is perpendicular to the direction of air-flow, air door is opened after blower fan work, pipeline and each dust sucting point is made to form negative pressure, light weight sundries in material and dust enter dust shield, and the foreign material that volume is larger are blocked by grid, cannot enter cleaning shaft, the dust that particle is tiny then enters pipeline and deduster by grid, reaches the object of foreign material and dust separation.This mode Problems existing is: 1, the dust sucting point of every platform deduster is more, and compares dispersion, and therefore the quantities of installation and maintenance grid is very large, adds the labour intensity of engineering cost and operating personnel.2, grid after being blocked by foreign material not in time cleaning can reduce draught area, reduce the air quantity of dust sucting point, affect dust removing effects.3, in order to ensure that dust does not deposit, cleaning shaft diameter determines according to the minimum speed of different densities dust, after the grid on dust shield is blocked by foreign material, wind speed in dedusting main pipeline is caused to reduce, when the minimum speed that wind speed does not deposit lower than dust, dust will be deposited in pipeline, and blocking pipe affects dust removing effects.If the dust stratification deposited can not get cleaning for a long time and to make moist caking, cause needing to change dedusting main pipeline.4, when clearing up the foreign material on grid, the bottom that staff must be positioned at dust shield can operate, therefore Boiler pressure control butterfly valve must be closed before operation, for the blower fan not having the dust sucting point of Boiler pressure control butterfly valve will stop deduster, could operate when should confirm there is no air-flow, if do not carry out operation as requested, there is certain potential safety hazard in the personal safety of staff.5, the cleaning cycle of deduster is short, and clearing times is many; Prune job adds the labour intensity of staff and the startup-shutdown number of times of deduster frequently.
Second method adds grid (as shown in Figure 2) in cleaning shaft inside; this method also also exists the problem of exist in above-mentioned first method 2,3,5; in addition; when clearing up the grid of this form; staff will open peep hole, enters pipe interior, in order to improve security; the generation of prevention security incident, staff can must clear up in fan of dust remover shutdown situation.
