Abstract
The utility model discloses an anti-blocking type coal spreading opening, which belongs to a boiler coal bin coal spreading opening. A coal spreading air duct is manufactured into a round pipeline; one side of the coal spreading air duct is provided with a blowing and sweeping tar air chamber communicated with the coal spreading air duct; the blowing and sweeping tar air opening of the blowing and sweeping tar air chamber is communicated with the lower opening of a coal drop pipe. As an ordinary coal feeding opening is divided into an upper row, a middle row and a lower row; when mounting, a route of blowing and sweeping air is led from the lower row of the coal spreading air duct to continuously implement blowing and sweeping on the tar stuck on the coal opening and to prevent the tar from being piled up on the coal opening to affect the normal feeding of the boiler. The anti-blocking type coal spreading opening has the beneficial effects of simple manufacturing and convenient mounting, completely solves the plugging and burning through phenomena at the coal feeding opening of the boiler and guarantees the normal running of the boiler.
Description
Technical field
The utility model relates to the boiler coal bunker and broadcasts the coal mouth, specifically is that a kind of block-resistant type is broadcast the coal mouth.Be specially adapted to CFBB.
Technical background
Existing CFBB, its coal feeding hole is general to adopt row, middle row, arrange coal spread wind (from a hot blast) down broadcasts the coal mode, if coal tar content is higher, coal tar is bonded in coal feeding hole after operation a period of time, cause coal feeding hole to stop up, so that coal feeding hole takes place burns phenomenon, finally has only boiler pressuring fire is handled.Influenced the safety and steady operation of unit.
Summary of the invention
The utility model provides a kind of block-resistant type to broadcast the coal mouth, is used to overcome the above-mentioned drawback of prior art.
The utility model is realized with following technical scheme: a kind of block-resistant type is broadcast the coal mouth, comprise coal spout, the top of coal spout is a coal dropping port, the zone that is communicated with coal spread wind pipe and coal spout in the coal spout bottom is equipped with the coal spread wind ventilating opening, side at coal spout is provided with the coal spread wind pipe, it is characterized in that the coal spread wind pipe is a circular pipe; Side at the coal spread wind pipe is provided with the purging tar air compartment that is communicated with the coal spread wind pipe, and the purging tar air port that purges the tar air compartment communicates with the end opening of coal spout.
Because general coal feeding hole divides and goes up row, middle row, arranges three rows down, during installation under arrange the coal spread wind pipeline and draw one the tunnel and purge wind, the tar to the coal feeding hole bonding purges always, prevents that tar from influencing the normal coal supply of boiler in the coal feeding hole accumulation.
The beneficial effects of the utility model are: make simply, easy for installation, thoroughly solved boiler coal feeding mouth chute blockage, burnt phenomenon, guaranteed that boiler normally moves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is that block-resistant type is broadcast coal mouth scheme of installation.
Among the figure: 1, coal spout, 1-1, coal dropping port, 2, the coal spread wind pipe, 3, purge the tar air compartment, 3-1, purge the tar air port, 4, the coal spread wind ventilating opening, 5, the boiler concentrated phase area.
The specific embodiment
As shown in Figure 1, coal spread wind pipe 2 is being guaranteed to be made into circular pipe under the constant situation of flow area, to increase rigidity and to reduce resistance, its upper end is coal dropping port 1-1.Make hole, garden long by 12～13, diameter ￠ 12～14 with arranging coal spread wind ventilating opening 4 down, increase and broadcast the coal flow velocity.Install purging tar air compartment 3 additional in coal spout 1 bottom.The zone that is communicated with coal spread wind pipe and coal spout in coal spout 1 bottom is equipped with coal spread wind ventilating opening 4.Install as shown in Figure 2, be installed in boiler concentrated phase area 5.From under arrange the coal spread wind pipeline and draw one the tunnel and purge wind to purging tar air compartment 3, blow out through purging tar air port 3-1, normally in service, coal is 1 whereabouts from coal dropping port 1-1 along coal spout, purge wind and the tar of bonding is purged always, prevent that tar from influencing the normal coal supply of boiler in the coal feeding hole accumulation.Thoroughly solve boiler coal feeding mouth chute blockage, burn phenomenon, guaranteed that boiler normally moves.
Claims (2)
1, a kind of block-resistant type is broadcast the coal mouth, comprise coal spout (1), coal spread wind pipe (2), the top of coal spout is coal dropping port (1-1), the zone that is communicated with coal spread wind pipe (2) and coal spout (1) in coal spout (1) bottom is equipped with coal spread wind ventilating opening (4), side at coal spout (1) is provided with coal spread wind pipe (2), it is characterized in that the coal spread wind pipe is a circular pipe; Side at coal spread wind pipe (2) is provided with the purging tar air compartment (3) that is communicated with coal spread wind pipe (2), and the purging tar air port (3-1) that purges the tar air compartment communicates with the end opening of coal spout.
2, block-resistant type according to claim 1 is broadcast the coal mouth, it is characterized in that coal spread wind ventilating opening (4) is the hole, garden of long 12～13mm, diameter ￠ 12～14mm.
