Abstract
The invention discloses a dust collecting method for a coal conveying system and belongs to the field of conveying technologies. The dust collecting method for the coal conveying system includes the following steps that (1) a baffle is additionally mounted, (2) a coal conveying belt sealing cover is additionally mounted, (3) dust is collected, and (4) secondary conveying is conducted. Through the dust collecting method for the coal conveying system, the dust flying in the coal granule conveying process is collected effectively and cannot adhere to conveying equipment, flying discharging of pulverized coal of the coal conveying system is treated thoroughly, the sanitation of the equipment and the sanitation of the surrounding environment are improved, and the occupational health and safety of staff are guaranteed.
Description
Technical field
The present invention relates to sugaring field, specifically a kind of coal handling system dust collection method.
Background technology
The coal handling system of the coal burning boiler related in sugaring field all can produce a large amount of airborne dusts in raw coal preparation and course of conveying, affect occupational health and coal yard surrounding devices, the on-the-spot health of employee, so it is the important work of enterprise one that the collection of airborne dust is administered, mainly the ways such as dust exhaustor are installed administer by water mist sprinkling, load transfer device junction, but effect is not all clearly.The moisture content of dust can be increased with water mist sprinkling, most band pigment dirt is bonded on equipment, equipment easily produces the difficult cleaning of corrosion, space, load transfer device junction is less, only at this, dust exhaustor is installed and collects fraction dust only, major part airborne dust can continue to fly upward with conveying process flow operation, can not thoroughly administer.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and does not produce a kind of coal handling system dust collection of a large amount of airborne dust method.
The present invention takes following technical scheme:
A kind of coal handling system dust collection method, comprises the following steps:
(1) striker plate is installed additional
Coal crushes outlet enters mounting block flitch in coal transportation belt funnel, with inner wall of hopper in about 45 °, flows into No. 1 coal transportation belt after making coal crushes coal grain out fall into striker plate buffering, shortens drop and reduce to fling and the dust that produces;
(2) coal transportation belt seal closure is installed additional
No. 1 coal transportation belt feeding mouth to discharging opening transportation rubber belt close encapsulation, install 1-2 tablecloth bag dust collector and connect sweep-up pipe in seal groove, make to form negative pressure in seal groove, dust can not be raised outward;
(3) dust collection
By bag dust collector inside arrange air suctiton ventilator by dust collection in cloth bag;
(4) second-pumping
At the funnel place mounting block flitch of No. 1 coal transportation belt to 2 coal transportation belt, with inner wall of hopper in about 45 °, No. 2 coal transportation belts are flowed into after making No. 1 coal transportation belt coal grain out fall into striker plate buffering, shorten drop and reduce and fling and the dust that produces, and extend 3 meters of section close encapsulation at No. 2 coal transportation belt feeding mouths, the airborne dust making this produce is cushioned again, and access sweep-up pipe cause bag dust collector collect.
The invention has the beneficial effects as follows: actv. collects the dust that coal grain flies upward in course of conveying, dust can not be bonded on load transfer device, the discharge of flying upward of the thorough coal dust administering coal handling system improves equipment and environmental health around, and the career safety & health of employee is protected.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention
Detailed description of the invention
With an embodiment, the invention will be further described below
A kind of coal handling system dust collection method, comprises the following steps:
(1) striker plate is installed additional
Coal crushes outlet enters mounting block flitch in coal transportation belt funnel, with inner wall of hopper in about 45 °, flows into No. 1 coal transportation belt after making coal crushes coal grain out fall into striker plate buffering, shortens drop and reduce to fling and the dust that produces;
(2) coal transportation belt seal closure is installed additional
By No. 1 coal transportation belt feeding mouth to discharging opening transportation rubber belt close encapsulation, install 1-2 tablecloth bag dust collector and connect sweep-up pipe in seal groove, make to form negative pressure in seal groove, dust can not be raised outward;
(3) dust collection
By bag dust collector inside arrange air suctiton ventilator by dust collection in cloth bag;
(4) second-pumping
At the funnel place mounting block flitch of No. 1 coal transportation belt to 2 coal transportation belt, with inner wall of hopper in about 45 °, No. 2 coal transportation belts are flowed into after making No. 1 coal transportation belt coal grain out fall into striker plate buffering, shorten drop and reduce and fling and the dust that produces, and extend 3 meters of section close encapsulation at No. 2 coal transportation belt feeding mouths, the airborne dust making this produce is cushioned again, and access sweep-up pipe cause bag dust collector collect.
Raw coal is after the fragmentation of coal crushes high-speed operation, coal dust content increases, produce the funnel that a large amount of air-flows falls into outlet together with coal dust simultaneously, to tilt 45 ° of striker plates in the installation one piece that enters in funnel to increase respectively of this funnel and coal transportation belt, make coal grain by former fling to fall into coal transportation belt face changes coal grain into and first falls striker plate and flow on coal transportation belt face again, shorten the drop of coal grain.Seal at the coal transportation belt of the outlet of these two funnels, the air-flow making exit fly upward out and coal dust are sealed, cannot toward leaking outside, air-flow and coal dust speed of flying upward is reduced greatly, and part, from resedimentation, installs a tablecloth bag dust collector, in the coal transportation belt of its sweep-up pipe access sealing, make to form negative pressure in seal groove, dust can not be raised outward, the air-flow and coal dust that do not have sedimentation is pumped in dust exhaustor and collects.The present invention can collect flying upward of the coal dust that coal crushes produces to the whole flow process of coal transportation belt discharging opening completely, and equipment and ambient environment are greatly improved.
