Description

A kind of high-temperature tail gas deduster
Technical field
The present invention relates to a kind of dust arrester, be specifically related to a kind of high-temperature tail gas deduster.
Background technology
In prior art, containing more dust granules in high-temperature tail gas (such as blue-gas generator, boiler etc.), along with tail gas is discharged, because its temperature high speed is fast, it is comparatively large to the wearing and tearing of deduster, reduces the service life of cleaner.And need to carry out a large amount of water spray removals in the process of dedusting, the particle in tail gas flows out along with water, easily again enters in air, and common deduster water consumption is larger.Traditional deduster and chimney are set up separately, occupy larger space.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of high-temperature tail gas deduster.
Technical scheme of the present invention is: a kind of high-temperature tail gas deduster, comprise deduster body, cyclone cylinder, the bottom of described deduster body has put aqueous water, deduster body upper part is respectively arranged with air inlet and air outlet, described cyclone cylinder lower end inner wall place is installed on support ring, described support ring offers at least one through hole, described through hole is provided with ash tube, and described support ring is also welded with whirlwind flabellum, liquid distribution is provided with in described cyclone cylinder, described deduster body bottom portion is provided with slag notch and overfall, and the dewatering outlet that described deduster body sidewall is arranged.
Further improvement of the present invention comprises:
Described air outlet is also connected with chimney by a cyclone cylinder.
Channel-section steel straight down is also installed between the air inlet of described deduster body and air outlet.
Dividing plate straight down is also installed between the air inlet of described deduster body and air outlet.
Ash tube be arranged at position between rotary fan and deduster inner body wall and ash tube lower end lower than overfall 30-60 centimetre.
Described deduster body is fixed on a support, and described chimney is provided with wind rope.
This deduster has efficiently, invest little, space-saving advantage.The solid particle being simultaneously convenient to high-temperature tail gas is recycled.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1, a kind of high-temperature tail gas deduster of the present invention, comprise deduster body, cyclone cylinder, the bottom of described deduster body has put aqueous water, deduster body upper part is respectively arranged with air inlet and air outlet, described cyclone cylinder lower end inner wall place is installed on support ring, described support ring offers at least one through hole, described through hole is provided with ash tube, and described support ring is also welded with whirlwind flabellum, liquid distribution is provided with in described cyclone cylinder, described deduster body bottom portion is provided with slag notch and overfall, and the dewatering outlet that described deduster body sidewall is arranged.
Further improvement of the present invention comprises:
Described air outlet is also connected with chimney by a cyclone cylinder.
Channel-section steel straight down is also installed between the air inlet of described deduster body and air outlet.The channel-section steel be arranged between import and whirlwind flabellum can make high-temperature tail gas form an airflow space in import, has the effect reducing high-temperature tail gas flow velocity.
Dividing plate straight down is also installed between the air inlet of described deduster body and air outlet.
Ash tube be arranged at position between rotary fan and deduster inner body wall and ash tube lower end lower than overfall 30-60 centimetre.
Described deduster body is fixed on a support, and described chimney is provided with wind rope.
This deduster has efficiently, invest little, space-saving advantage.The solid particle being simultaneously convenient to high-temperature tail gas is recycled.
Described ash tube is arranged at the position between rotary fan and deduster inner body wall.
The design is made up of high-temperature tail gas import, cleaner body, whirlwind flabellum, ash tube, spray system, overflow system, slag-drip opening, chimney and wind rope system.Its operation principle is:
High-temperature tail gas dives downwards through air inlet and enters in deduster, the solid that in tail gas, particle is larger has larger kinetic energy and can directly pour in the water of deduster bottom, more short grained solid can enter whirlwind flabellum along with high-temperature gas turns to through 180 degree, because whirlwind flabellum centre is blind plate, high-temperature tail gas can form swirling eddy automatically along the angle of inclination of whirlwind flabellum, solid granule in swirling eddy can from top liquid distribution shower in water contact, thus increase the weight of solid granule, increase the inertia of solid granule, granule and the globule can be collided with dedusting wall, the current formed can fall along dedusting wall, to enter between whirlwind flabellum and dedusting wall in ash tube, enter along ash tube in the water of deduster bottom.So just the solid particle in high-temperature tail gas can be removed.
The comparatively solid small particles fallen into bottom deduster directly can flow away along overflow pipe, and the solid of larger particles is by regular the draining of slag-drip opening.
The advantage of the design is that high-temperature tail gas adopts the mode of diving to enter deduster from import department, because deduster bottom is water, can reduce high temperature gas flow, particularly larger solid particle washing away deduster in high-temperature tail gas, increase the service life of deduster; The channel-section steel be arranged between import and whirlwind flabellum can make high-temperature tail gas form an airflow space in import, has the effect reducing high-temperature tail gas flow velocity; The spray of the liquid distribution that top is arranged can play the effect of the temperature reducing high-temperature tail gas and the inertia increasing solid granule, both contributed to removing the solid granule in high-temperature tail gas, be conducive to again the temperature reducing deduster, reach the object of protection deduster, extend the service life of deduster further; The whirlwind flabellum arranged can be automatically converted to high-temperature tail gas the effect of swirling eddy; Chimney is directly installed on deduster top and can saves space.
The present invention does not need the equipment such as similar electrostatic precipitation equally to consume the energy, does not have similar screen pack, dust settling pocket etc. easily to consume consumptive material yet.
This deduster has efficiently, invest little, space-saving advantage.The solid particle being simultaneously convenient to high-temperature tail gas is recycled.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
