Abstract

The utility model relates to a boiler multitube dust collector, include the lower smoke box and the last smoke box that separate by horizontal metal partition, flue gas entry and ash hole have been seted up down on lateral wall and the diapire of smoke box respectively, the exhanst gas outlet has been seted up on the lateral wall of last smoke box, the last mounting hole of offering the dot matrix and arranging of metal partition, the ceramic pipe passes through the mounting hole fixed connection be in metal partition is last, go up the smoke box through many the ceramic pipe with the smoke box communicates down, the ceramic pipe is in go up the interior duct length homogeneous phase of smoke box etc, pipeline under the ceramic pipe is in in the smoke box is short more apart from bigger its length of probe distance of flue gas entry, at least the half the lower extreme open position of ceramic pipe is less than the lower border position of flue gas entry. The beneficial effects of the utility model are that, its elementary boiler flue gas dust removal who can be used to before whirlwind disconnect -type multi -tube dust cleaner or the water smoke formula gas wash tower effectively detaches large granule smoke and dust or caking ash group.

Description

A kind of boiler multi-pipe dust arrester

Technical field

The utility model belongs to boiler smoke dust removal field, is specifically related to a kind of boiler multi-pipe dust arrester.

Background technology

Cyclone separating multi-tube dust cleaner is boiler smoke dust collection method conventional both at home and abroad, there is small investment, the advantages such as volume is little, but when using it for the process flue gas that dust content is high because combustion efficiency is bad, bulky grain flue dust or the caking ash group of burning insufficient, be easy to the Whirlwind cyclone blocking minor diameter, high speed, the life-span of this kind of deduster is shortened greatly.

Utility model content

Technical problem to be solved in the utility model is for above-mentioned technical problem, a kind of boiler multi-pipe dust arrester is provided, it can be used for the elementary boiler smoke dedusting before cyclone separating multi-tube dust cleaner or water-fog type gas wash tower, effectively removing bulky grain flue dust or caking ash group.

The technical scheme that the utility model solves the problems of the technologies described above is as follows:

A kind of boiler multi-pipe dust arrester, comprise the lower smoke box and upper smoke box that are separated by horizontal metal dividing plate, the sidewall of described lower smoke box offers smoke inlet, the diapire of described lower smoke box offers ash hole, the sidewall of described upper smoke box offers exhanst gas outlet, described metal partion (metp) offers the installing hole of lattice arrangement, earthenware is fixedly connected on described metal partion (metp) by described installing hole, described upper smoke box is communicated with described lower smoke box by many described earthenwares, the duct length that described earthenware is in described upper smoke box is all equal, horizontal range its length larger that described earthenware is in the pipeline distance smoke inlet in lower smoke box is shorter, at least the lower ending opening position of the described earthenware of half is lower than the position, lower edge of described smoke inlet.

The beneficial effects of the utility model are, the flue gas that dust content is high collides with the densely covered earthenware in lower smoke box after the smoke inlet of lower smoke box enters, flow velocity reduces, and oarse-grained flue dust or caking ash group are deposited on the bottom of described lower smoke box because of collision and Action of Gravity Field, realize elementary dedusting; Horizontal range its length larger that earthenware is in the pipeline distance smoke inlet in lower smoke box is shorter, said structure arrange can ensure to have larger space in lower smoke box and shorter earthenware lower ending opening at the bottom of lower smoke box case away from, not easily block, guarantee that the flue gas through rough dusting can enter upper smoke box through earthenware glibly.

On the basis of technique scheme, the utility model cannot do following technological improvement further:

Further, the outermost central point of the installing hole of described one-tenth lattice arrangement in turn line forms a rectangle, described rectangle parallel or vertical with described smoke inlet place flue gas direction of advance.

Further, the internal diameter of described earthenware is 8 ~ 15cm, and the quantity of described earthenware is at least 30.

Further, the gap width between adjacent described earthenware outer wall is 2 ~ 5cm.

Further, the sidewall of described upper smoke box offers shoot door one, the sidewall of described lower smoke box offers shoot door two.

Adopt the beneficial effect of above-mentioned further scheme to be that installing hole latticed form is arranged to rectangular array, conveniently install, process and good dedusting effect; Earthenware internal diameter is set to 8 ~ 15cm, and the quantity of described earthenware is at least 30, and the resistance when earthenware of this kind of size and quantity can ensure flow of flue gas is less; Gap width between adjacent described earthenware outer wall is 2 ~ 5cm, makes large caking ash group not easily through gap; Shoot door one and shoot door two are set, timing can be carried out to upper smoke box and lower smoke box and clear up maintenance.
