Description

Grooved spark catcher

Technical field

The utility model relates to a kind of spark catcher, is specifically related to a kind of grooved spark catcher with higher arresting efficiency.

Background technology

Have many differences compared with the coal-burning boiler that biomass direct combustion power generation boiler and technology are more ripe, its supporting flue gas dust collecting system also has a great difference.Because domestic biomass fuel contains more impurity, and gray density is comparatively light, and therefore can produce much imperfect combustion carbon granule in combustion and discharge with flue gas, the part in these carbon granules is still in the state of glowing, and becomes the spark in flue gas.

Very easily make the cloth bag of sack cleaner cause earlier period damage containing more bulky grain ash and spark in flue gas, affect deduster and normally run.Therefore, biomass direct-combustion boiler needs to arrange cyclone dust collectors before sack cleaner, as the pre-dedusting of cloth bag, in order to the larger ash particle of removing and spark, in order to avoid it causes damage to cloth bag.Pre-dedusting being set before sack cleaner and also having similar way in other industry, having plenty of the load of dust remove in order to alleviate cloth bag, having plenty of to remove spark protection cloth bag.

With the pre-dedusting of cyclone dust collectors as sack cleaner, although spark and bulky grain ash effectively can be removed, also there are some problems.Such as: because the entrance cigarette speed of cyclone dust collectors is higher, be generally 15 ~ 20m/s, therefore resistance is also larger, and usually at about 1500Pa, consequent power consumption is also larger; Equally because cigarette speed is high, the wearing and tearing of cyclone cylinder are also relatively more serious, and its inwall needs the Precautionary Measure of higher level, and needs lasting maintenance.

Groove profile segregator is the one of inertia separator, adopts groove profile segregator as pre-dedusting, because its cigarette speed is lower, therefore has that resistance is little, the feature of light abrasion; And because water-cooling vibration furnace grate biomass direct-combustion boiler back-end ductwork lateral dimension is wider, just in time large with groove profile segregator entrance section feature is coincide, variable cross-section is not needed just can be directly connected with groove profile segregator assembly, compared with cyclone dust collectors, the layout of groove profile segregator is compacter, and space is more saved.

Utility model content

The purpose of this utility model is to provide a kind of grooved spark catcher with higher arresting efficiency, and this spark catcher effectively can reduce the content of spark in biomass direct-combustion boiler flue gas and bulky grain dust.

In order to realize above-mentioned target, the utility model adopts following technical scheme:

A kind of grooved spark catcher, comprise: housing (1) and cell body (2), aforementioned cell body (2) is in " U " font, many rows are arranged in the inside of housing (1) vertically downward, adjacent the lining up in front and back is staggered in arrangement, be linked into a whole with fritter junction steel plate between each cell body (2), the upper end of cell body (2) is welded with housing (1), it is characterized in that, also comprise: flexible absorbing energy layer (3), foregoing soft absorbing energy layer (3) is pasted onto on the inner bottom surface of cell body (2).

Aforesaid grooved spark catcher, is characterized in that, the depth-width ratio of aforementioned cell body (2) is 1:1, and length is determined according to separator inlet size.

Aforesaid grooved spark catcher, is characterized in that, spacing, the trestle column of aforementioned cell body (2) are equal with the height of cell body (2).

Aforesaid grooved spark catcher, is characterized in that, what foregoing soft absorbing energy layer (3) adopted is aluminosilicate refractory fiber felt.

Usefulness of the present utility model is: on the inner bottom surface of cell body after sticking flexible absorbing energy layer; because flexible absorbing energy layer can absorb the kinetic energy hitting the particle come; effective minimizing particle bounce; and then reduce the amounts of particles flowing into rear groove body; so spark catcher of the present utility model effectively can reduce the content of spark in biomass direct-combustion boiler flue gas and bulky grain dust, there is higher arresting efficiency.

The implication of Reference numeral in figure: the flexible absorbing energy layer of 1-housing, 2-cell body, 3-.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.

With reference to Fig. 1, Fig. 2 and Fig. 3, grooved spark catcher of the present utility model comprises: housing 1, cell body 2 and flexible absorbing energy layer 3.

Respectively housing 1, cell body 2 and flexible absorbing energy layer 3 are introduced below.

One, housing

Housing 1 is surrounded by steel plate; all weld seams of steel plate require sealing; completely unlimited before housing 1; form air flow inlet; become suitable water conservancy diversion tapering and leave air stream outlet after housing 1; flue-dust retainer is set in the bottom of housing 1, to take the spark and bulky grain ash that cell body 2 traps in, leaves ash hole under flue-dust retainer in order to connect defeated grey equipment.

Two, cell body

Cell body 2 is in " U " font, many rows are arranged in the inside of housing 1 vertically downward, adjacent the lining up in front and back is staggered in arrangement, be linked into a whole with fritter junction steel plate between each cell body 2, the layout of junction steel plate can not hinder the motion of air-flow and particle, the upper end of cell body 2 is welded with housing 1, and the lower end of cell body 2 is also welded with housing 1, but this welding can not hinder ash particle to flow downward along cell body 2.

The depth-width ratio of cell body 2 is 1:1, and length is determined according to separator inlet size.

Spacing, the trestle column of cell body 2 are equal with the height of cell body 2.

Three, flexible absorbing energy layer

Flexible absorbing energy layer 3 is pasted onto on the inner bottom surface of cell body 2.Flexible absorbing energy layer 3 preferably adopts aluminosilicate refractory fiber felt.

Grooved spark catcher of the present utility model, its operation principle is as follows:

The flue gas containing spark and dust of being discharged by boiler back end ductwork flows to the entrance of this spark catcher; interval between flue gas flows through by cell body is discharged by outlet after bending repeatedly; spark in flue gas and bulky grain ash can not be turned with flue gas completely due to the effect of inertia; but directly hit bottom cell body; wherein a part of particle loses inertia; fall under gravity into flue-dust retainer below, another part ash then can rebound to hit bottom next row cell body in flue gas stream again and repeat aforesaid process until bump against last emissions groove body.The spark and the ash that fall into flue-dust retainer are discharged by defeated grey equipment, and Spark catcher process completes.The flexible absorbing energy layer pasted at cell body inner bottom surface can absorb the kinetic energy hitting the particle come; effectively alleviate particle bounce; and then reduce the amounts of particles flowing into rear groove body; so spark catcher of the present utility model effectively can reduce the content of spark in biomass direct-combustion boiler flue gas and bulky grain dust, there is higher arresting efficiency.

As can be seen here, cyclone separator is replaced with grooved spark catcher of the present utility model, higher arresting efficiency can be obtained, the pre-dust removal requirement of sack cleaner can be met completely, can also significantly reduce flowing resistance, power consumption simultaneously, greatly alleviate the wearing and tearing of pre-cleaner, flue is arranged also more succinct.

It should be noted that, above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
