Abstract
The invention provides a dedusting tube for flue gas, which relates to environmental-protection treatment equipment and particularly relates to a dedusting device capable of trapping dust in the flue gas. The invention has the technical scheme that: the dedusting tube comprises a cylindrical tube body; a gas inlet is arranged at an upper part of the tube body; the dedusting tube further comprises a gas exhaust tube and a gas guide spiral; the gas guide spiral is fixedly arranged on an inner wall of the tube body from top to bottom, wherein the axial line of the tube body is the axle center of the gas guide spiral; and a gap I is retained between the lower end of the gas guide spiral and the bottom surface of the tube body. According to the invention, the descending spiral is arranged in the tube body, the bottom-to-top gas exhaust tube is fixedly arranged at a middle part of the spiral, the spiral, the tube body and the gas exhaust tube form a descending flue gas guide passage, high-temperature flue gas flows along the passage from top to bottom, and particles in the high-temperature flue gas fall into an inverted cone body at the bottom of the tube body under the action of gravity; and then, the high-temperature flue gas is discharged along the gas exhaust tube from bottom to top and is supplied to other heat-consuming devices for use.
Description
Technical field
The present invention relates to environmental protection treatment equipment, relate in particular to a kind of dust arrester that can hold back dust in the flue gas.
Background technology
The hot waste gas (flue gas) that equipment such as boiler are discharged, temperature reaches 140-180 ℃; Directly be disposed in the atmosphere, wasted a large amount of heat energy on the one hand, the particulate in the hot waste gas can produce bigger pollution to environment on the other hand.
Prior art is a lot of for the processing method of flue gas, and chemical method, physics method are arranged, and gathers both methods in addition.But the equipment cost of their common characteristic is high, and use cost is high; And cooling is one of its main purpose.
Summary of the invention
The present invention is directed to above problem, providing a kind of can not reduce the flue gas ash removal tube of flue-gas temperature with particulate trap in the flue gas.
Technical scheme of the present invention is: comprise columniform cylindrical shell, said cylindrical shell top is provided with air inlet, also comprises aiutage and wind-guiding spiral; Said wind-guiding spiral and is wind-guiding spiral axle center by tubular axis from top to bottom, is fixedly installed on the inwall of said cylindrical shell; Leave gap one between the lower end of said wind-guiding spiral and cylindrical shell bottom surface;
Said aiutage is arranged on the cylindrical shell center, is fixedly connected said wind-guiding spiral; Said aiutage is upper and lower uncovered, leaves gap two between said aiutage end opening and cylindrical shell bottom surface;
Said cylindrical shell bottom surface is provided with dust-exhausting port.
Said cylindrical shell bottom is turbination, and said dust-exhausting port is located at conical vertex of a cone position.
Said air inlet is communicated with the tube chamber between said wind-guiding spiral and cylindrical shell by the tangential in said cylindrical shell cross section.
The present invention is provided with " decline " spiral in cylindrical shell; Fixedly install from the bottom to top an aiutage at spiral middle part; Spiral, cylindrical shell and aiutage have constituted the flue gas flow-guiding channel of one " decline "; High-temperature flue gas is from top to down along this channel flow, and particulate wherein is in the gravity effect drops to the inverted cone of cylindrical shell bottom.High-temperature flue gas is discharged along aiutage more from the bottom to top, offers other and utilizes with thermic devices.

The specific embodiment
The present invention comprises columniform cylindrical shell 7 like Fig. 1, shown in 2, and said cylindrical shell 7 tops are provided with air inlet 1, also comprise aiutage and wind-guiding spiral 6; Said wind-guiding spiral 6 and is spiral 6 axle center by cylindrical shell 7 axis from top to bottom, is fixedly installed on the inwall of said cylindrical shell 7; Leave gap one between the lower end of said spiral 6 and cylindrical shell 7 bottom surfaces;
Said aiutage is arranged on cylindrical shell 7 centers, is fixedly connected said spiral 6; Uncovered on the said aiutage (aiutage outlet 2), lower open mouth (aiutage import 5) leave gap two between said aiutage end opening (aiutage import 5) and cylindrical shell 7 bottom surfaces;
Said cylindrical shell 7 bottom surfaces are provided with dust-exhausting port 3.
Said cylindrical shell 7 bottoms are turbination 4, and said dust-exhausting port 3 is located at conical vertex of a cone position.
Said air inlet 1 is communicated with the tube chamber of 7 of said wind-guiding spiral 6 and cylindrical shells by the tangential in said cylindrical shell 7 cross sections.
