Abstract
The invention provides a dedusting device 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 dedusting device comprises an outer tube, an inner tube, a gas outlet pipe, a gas inlet passage and a gas guide spiral, wherein the inner tube is offset in the outer tube, the gas outlet pipe is arranged in the inner tube, the gas inlet passage is in communication with a flue gas source and the inner tube and is arranged in the outer tube, and the gas guide spiral is arranged between the inner tube and the gas outlet pipe. According to the invention, the outer tube and the inner tube are arranged, during the process that dust-contained flue gas spirally ascends in the gas inlet passage of the outer tube, partial larger dust particles fall firstly; after the dust-contained flue gas enters the inner tube, a gas passage is lengthened under the action of the gas guide spiral, and more gathering spaces are provided for fine particles, so that the fine particles fall to the bottom of a tube body; and cleaner flue gas is discharged out of the tube body from the gas outlet pipe and is supplied to other heat-consuming devices for use. Compared with the filtering type, cooling type and spraying type dedusting devices, the dedusting device provided by the invention has the advantages of low cost and high efficiency.
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 fume dust remover of flue-gas temperature efficiently with particulate trap in the flue gas.
Technical scheme of the present invention is: comprise urceolus, be offset to the inner core in the urceolus, be located at the escape pipe in the inner core, be arranged on the air intake duct that is communicated with said flue gas source and inner core in the urceolus, and be located at the air guide spiral between inner core and the escape pipe;
Outer tube bottom is provided with the dust mouth;
Interior tube bottom is uncovered, to be communicated with the tube chamber of said urceolus;
Inner core top is provided with the inner core air inlet; Said air intake duct is communicated with the air inlet on said inner core top.
The inlet of said air intake duct runs through the barrel of said urceolus, and highly is lower than said air inlet height; Said air intake duct is arranged in the urceolus with spiralling form.
Said air intake duct cross section is the uncovered shaped as frame in bottom.
The present invention is provided with outer, inner core, and in the spiral uphill process, the grit that part is bigger falls earlier ash-laden gas in the air intake duct of urceolus.After getting into inner core again, under the effect of air guide spiral, air flue prolongs, and gives more " gathering " space of particulate to drop to the bottom of cylindrical shell.Then external than clean flue gas from the escape pipe expelling tube, offer other and utilize with thermic devices.With respect to filtering type dedusting, cooled, fountain dust arrester, dust arrester cost of the present invention is low, efficient is high.

The specific embodiment
The present invention comprises urceolus 1 like Fig. 1,2, shown in 3, is offset to the inner core 7 in the urceolus 1, is located at the escape pipe 6 in the inner core 7, is arranged on the air intake duct 9 that is communicated with said flue gas source and inner core 7 in the urceolus 1, and is located at the air guide spiral 5 between inner core 7 and the escape pipe 6;
Urceolus 1 bottom is a conical bottom 2, and is provided with dust mouth 3 in its lowest position;
Inner core 7 bottoms are uncovered 4, to be communicated with the tube chamber of said urceolus 1;
Inner core 7 tops are provided with inner core air inlet 8; Said air intake duct 9 is communicated with the air inlet 8 on said inner core 7 tops.
The inlet 10 of said air intake duct 9 runs through the barrel of said urceolus 1, and highly is lower than said air inlet 8 height; Said air intake duct 9 is arranged in the urceolus 1 with spiralling form.
Said air intake duct 9 cross sections are the uncovered shaped as frame in bottom.
