Abstract
The utility model provides a high-temperature flue gas deduster, aiming at solving the problems that under the working condition of high flue gas corrosivity, a filter bag at high temperature is required to be replaced within a few months, the running expense and the maintaining work load are increased, and inconvenience is brought to users. The high-temperature flue gas deduster provided by the utility model comprises a gas intake smoke box, wherein the gas intake smoke box is connected with a bag-type deduster. The high-temperature flue gas deduster is characterized in that the gas intake smoke box is internally provided with a circulation water pipe; a water intake pipe of the circulation water pipe is connected with a water supplying tank; a water exhaust pipe of the circulation water pipe is connected with a hot water tank; the upper part of the gas intake smoke box is provided with a blowing device; the lower part of the gas intake smoke box is provided with a dust collecting bucket. The high-temperature flue gas deduster provided by the utility model is used for high-temperature flue gas dedusting.
Description
technical field:
The utility model relates to a kind of environmental protection equipment, is specifically related to a kind of dust collector for high-temperature flue.
background technology:
High-temperature flue gas refer to temperature 260 ℃ of left and right, the industrial waste gas that contains a large amount of dust, these waste gas are mainly from industrial departments such as cement plant, metallurgical works, garbage burning factories, this class waste gas, as purifying and dedusting not, will cause serious environmental pollution.Domestic main employing sack cleaner carries out dedusting to these waste gas at present, and the key equipment of deduster is filter bag, and the efficiency of dust collection key of filter bag depends on filter cloth, the disadvantage of sack cleaner is to change filter bag, because the kind of filtrate is few, quality is not good enough, bagging technology not too reaches a standard, and the other reasons of dust pelletizing system, life-span of the filter bag is short, filter bag especially at high temperature, under the strong working condition of flue gas corrosion, the short some months time having must be changed filter bag, has increased running expense and maintenance workload, to user, makes troubles.
summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of dust collector for high-temperature flue, adopt circulation first high-temperature flue gas to be lowered the temperature, avoided the injury of high-temperature flue gas to filter bag, extend the service life of filter bag, cost-saving, circulation is carried out high temperature heat exchange simultaneously becomes hot water later, can be for living area water or heating water, take full advantage of heat, economize on resources.
Above-mentioned object realizes by following technical scheme:
Dust collector for high-temperature flue, comprise air inlet smoke box, described air inlet smoke box connects sack cleaner, circulating water pipe is installed in described air inlet smoke box the inside, the water inlet pipe of described circulating water pipe connects supply tank, the outlet pipe of described circulating water pipe connects boiler, and blowing device is installed on described air inlet smoke box top, and described air inlet smoke box bottom is provided with flue-dust retainer.
Described dust collector for high-temperature flue, described circulating water pipe adopts tube-sheet type pipe arrangement.
Described dust collector for high-temperature flue, described blowing device comprises air compressor, described air compressor connects air nozzle by winding-up pipeline.
Beneficial effect:
1, the utility model is installed circulating water pipe in the air inlet smoke box the inside of sack cleaner, first high-temperature flue gas passes through water pipe heat exchange after entering air inlet smoke box, the heat that water in water pipe has absorbed high-temperature flue gas becomes hot water, can supply domestic water or heating, take full advantage of heat, saved the energy, the water that simultaneously heat of high-temperature flue gas is recycled water pipe is taken away a part temperature of flue gas is declined, avoided the injury to the filter bag of sack cleaner, extended the service life of filter bag, saved entreprise cost, for fear of dust, on heat exchanging water pipe, gather and cause the heat exchange efficiency of water pipe to decline simultaneously, the utility model is provided with blowing device in air inlet smoke box the inside, regularly the dust on heat exchanging water pipe is jetted, guarantee heat exchanging water pipe's heat exchange efficiency.
2, circulating water pipe of the present utility model adopts tube-sheet type pipe arrangement, saves and takies volume, and heat exchange efficiency is high.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: 1, air inlet smoke box, 2, sack cleaner, 3, circulating water pipe, 4, supply tank, 5, boiler, 6, flue-dust retainer, 7, air compressor, 8, winding-up pipeline, 9, air nozzle.
the specific embodiment:
Embodiment 1:
As shown in Figure 1: dust collector for high-temperature flue of the present utility model, comprise air inlet smoke box 1, described air inlet smoke box connects sack cleaner 2, circulating water pipe 3 is installed in described air inlet smoke box the inside, the water inlet pipe of described circulating water pipe connects supply tank 4, the outlet pipe of described circulating water pipe connects boiler 5, and blowing device is installed on described air inlet smoke box top, and described air inlet smoke box bottom is provided with flue-dust retainer 6.
Embodiment 2:
Dust collector for high-temperature flue described in embodiment 1, described circulating water pipe adopts tube-sheet type pipe arrangement.
Embodiment 3:
Dust collector for high-temperature flue described in embodiment 1 or embodiment 2, described blowing device comprises air compressor 7, described air compressor connects air nozzle 9 by winding-up pipeline 8.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
