Abstract

The utility model relates to a dust catcher used in the coal burning boiler, consisting of a settling tank and a dust removal drum body; a clapboard is arranged in the middle of the settling tank, a side wall is provided with overflow holes and pollution discharge holes; the dust removal drum body is fixedly arranged at the settling tank, and a vertical clapboard and a folding clapboard are arranged in the drum body, separating the internal drum body into four communicated air chambers; the air chamber vertically communicated with a smoke inlet is provided with a tap water jet-pipe used for making water atomized to form a water curtain in the air chamber, so the smoke gas exhausted from the boiler achieves the aims of desulfurization and dust removal through two bouts of scouring and collision and the soaking of the water curtain in the dust catcher, and the release accords with the environmental requirement.

Description

Wet type desulfurizing dust collector

The utility model is the used deduster of a kind of improved coal-burning boiler.Existing coal-burning boiler, especially hand-fired boiler often are equipped with cyclone dust collectors or water dust scrubber smoke abatement and dust control, but cyclone dust collectors fume emission blackness does not reach environmental requirement, simultaneously can not desulfurization; Corrosivity is bigger because its cylindrical shell is under water for water dust scrubber, and service life is shorter, and BSW discharges easy generation secondary pollution together.

The purpose of this utility model is a kind of wet type desulfurizing dust collector of design, and its cylindrical shell is not under water, and corrosivity is little, long service life, smoke content, So in the flue gas that emits ₂The equal compliance with environmental protection requirements of concentration of emission and lingemann blackness.

The purpose of this utility model is achieved like this: wet type desulfurizing dust collector partly is made up of sedimentation basin and the cylindrical shell two that is installed on the sedimentation basin, partition wall vertically is set one in sedimentation basin, the top of sedimentation basin is divided into the portion of soaking and lime-ash portion, the bottom of sedimentation basin is still logical to be integral, soaking at the bottom of the pond of portion is tapered plane, laying ceramic tile on it slides in the hole of lime-ash portion sediment, the spout hole that is provided with suitable for reading of sedimentation basin one side, the bottom is provided with mudhole, the deduster cylindrical shell is installed in the portion that the soaks top of sedimentation basin, the top of one side has into mouth, the opposite side top is provided with exhaust opening, inner barrel is provided with together straight plate and two road flaps, the inner barrel space is divided into four air chambers that communicate, with the bottom of advancing the air chamber that mouth directly communicates one running water playpipe is set, the water atomization of being gushed out forms cascade one in this air chamber bottom, and boiler smoke is in the process of effluxing like this, pass one cascade and through the collision of washing away of two backhauls, thereby reach the purpose of desulfurization and dedusting.

Wet type desulfurizing dust collector that the utility model is carried is simple in structure, and is easy to maintenance, and equipment corrosion itself is little, and service life is long, smoke discharge amount, So ₂The equal compliance with environmental protection requirements of concentration and lingemann blackness.

Now in conjunction with the accompanying drawings wet type desulfurizing dust collector that the utility model is carried is further described.

Fig. 1 is the schematic diagram of wet type desulfurizing dust collector that the utility model is carried, as can be seen from Figure 1: wet type desulfurizing dust collector that the utility model is carried is mainly by sedimentation basin 1, cylindrical shell 4, advance mouth 15, exhaust opening 7 compositions such as grade, the middle part that is primarily characterized in that sedimentation basin 1 vertically is provided with partition wall 19, the top of sedimentation basin 1 is divided into portion of soaking 2 and lime-ash portion 20, the bottom of sedimentation basin 1 is still logical to be integral, soaking at the bottom of the pond of portion 2 is tapered plane, laying ceramic tile above slides in the heavy hole of lime-ash portion 20 sediment to deposit, the suitable for reading of one side of sedimentation basin 1 has spout hole 21 so that the water in the sedimentation basin 1 keeps certain height, the bottom of one side of sedimentation basin 1 has sewage draining exit 22 to discharge the water in the sedimentation basin 1 as required, cylindrical shell 4 is packed in the top of the portion that soaks 2 of sedimentation basin 1, simplified like this 4 corrosivity under water itself are little, the bosom of cylindrical shell 4 partly is provided with straight baffle 11, the cavity is left at the upper end of straight baffle 11 and cylindrical shell 4 tops, the bottom of straight baffle 11 connects dismountable plate washer 3 again, insert in the water of sedimentation basin 1 lower end of plate washer 3, the bilateral symmetry of straight baffle 11 ground respectively is provided with a right folding plate 9 and left folding plate 13 in the cylindrical shell 4, the top driving fit of the upper surface of right folding plate 9 and left folding plate 13 and cylindrical shell 4, the lower surface then is separated into four air chambers that communicate 8 with the inner space of cylindrical shell 4 like this with the baseplane of cylindrical shell 4 is neat mutually, 10,12,14, at the downward oblique side plate 5 that is welded of the lower left quarter of right folding plate 9, the right lower quadrant of left folding plate 13 is the oblique side plate 18 that is welded downwards, the lower left quarter of straight baffle 11 is the oblique side plate 16 that is welded downwards, the downward oblique side plate 6 that is welded on the close medial surface of exhaust opening 7 belows in the cylindrical shell 4, above-mentioned

side plate

5,18,16, the collision and the friction of 6 smokeshade when being used for controlling the size of exhaust gases passes and increasing the flue gas circulation, with the lower position that advances the air chamber 14 that mouth 15 directly communicates, running water playpipe 17 is housed on the cylindrical shell 4, running water sprays atomizing and forms cascade one in air chamber 14 bottoms from playpipe 17, like this under the effect of air-introduced machine and chimney (all drawing among the figure) draft, the flue gas that boiler is discharged enters in the deduster cylindrical shell 4 by advancing mouth 15, earlier pass cascade from air chamber 14, the air chamber 12 of flowing through again, 10 enter air chamber 8, entering chimney from exhaust opening 7 enters in the middle of the atmosphere, flue gas collides soaking with cascade through washing away of two backhauls, smokeshade wherein is deposited in the sedimentation basin 1, sulfur dioxide also acts in the water, just reached the purpose of desulfurization and dedusting, the emission of smoke tallies environmental requirement.
