Abstract
The utility model discloses a pretreatment device for removing dust from tail gas of a rotary kiln. The pretreatment device comprises a cavity, wherein an upper side of the cavity is provided with a gas inlet and a gas outlet; a heat exchange tube is arranged in the cavity; a lower portion of the cavity is a dust hopper; and a lower portion of the dust hopper is provided with a dust discharging port. The device provided by the utility model has simple structure, pre-treats tail gas of the rotary kiln, reduces temperature of tail gas of the rotary kiln, and removes a part of dust from tail gas so as to greatly prolong service life of dust removal bags in a bag type dust removal stage, and recover part of heat to be used for production and life.
Description
Technical field
The utility model relates to a kind of rotary kiln exhaust gas dedusting pretreating device.
Background technology
Contain a large amount of dust in the rotary kiln exhaust gas, just can discharge after needing dedusting up to standard.At present, what the rotary kiln exhaust gas dedusting was commonly used is bag-type dusting, also contains a large amount of heats in the rotary kiln exhaust gas, and when the rotary kiln exhaust gas temperature was too high, dust settling pocket can shorten service life, and simultaneously, a large amount of heats run off, and are unfavorable for sustainable development.
The utility model content
To the problems of the prior art, the purpose of the utility model is that a kind of rotary kiln exhaust gas dedusting pretreating device will be provided.
In order to achieve the above object, the technical scheme of the utility model is: a kind of rotary kiln exhaust gas dedusting pretreating device comprises cavity; Said cavity upside is provided with air inlet and gas outlet; Be provided with heat exchanger tube in the cavity, the cavity bottom is a dust hopper, and the dust hopper bottom is provided with dust-exhausting port.
The utility model is simple in structure, and rotary kiln exhaust gas is carried out preliminary treatment, reduces the rotary kiln exhaust gas temperature, and removes the dust in a part of tail gas, has improved the dust settling pocket service life in bag-type dusting stage greatly, and can be used for productive life by the recovery section heat.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, a kind of rotary kiln exhaust gas dedusting pretreating device comprises cavity 2, and said cavity 2 upsides are provided with air inlet 1 and gas outlet 4, are provided with heat exchanger tube 3 in the cavity 2, and cavity 2 bottoms are dust hopper 5, and dust hopper 5 bottoms are provided with dust-exhausting port 6.
The tail gas of rotary kiln is through cavity 2, and the part heat is absorbed by heat exchanger tube 3, and the part dust falls in the dust hopper 5.
All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into the protection domain of the utility model.
