Abstract
The utility model relates to a tail gas treatment device for a calcium carbide furnace, which comprises an inlet box. The inlet box is communicated to a bag dust collecting area provided with a plurality of bags, a plurality of baffle plates are arranged inside a communicating pipe for the inlet box and the bag dust collecting area, two neighboring baffle plates, one at the top and one at the bottom, are staggered to form a folded plate course of tail gas, a primary dust collecting bin is communicated with the bottom of a folded plate area formed by the baffle plates, and the bottom of the bag dust collecting area is communicated with a secondary dust collecting bin. The tail gas treatment device for the calcium carbide furnace is safe in dedusting without producing electric sparks to cause hazards, and is high in dedusting efficiency. By the aid of the folded plate area, the rate of the tail gas entering the bag dust collecting area is lowered, so that fume and dust in large particle size settle in the folded plate area, and the dedusting efficiency is effectively improved.
Description
Technical field
The utility model belongs to chemical machinery field, is specifically related to a kind of calcium carbide stove exhaust treating apparatus.
Background technology
The calcium carbide stove exhaust temperature is high, and according to the difference of furnace of calcium carbide operating condition, range of temperature is big, between 550 ℃-750 ℃, is about 600 ℃ under the normal condition generally; Dust content is big, and particle is superfine, and cementability is strong, and simultaneously tar content is high in the gas, reaches more than the 100mg/Nm3, separates out like the improper tar that will cause of temperature control, makes separation, conveying and the storage difficulty of dust in the flue gas like this; Furnace gas is a flammable explosive gas, belongs to hazardous chemical, and is high to the sealing requirements of treatment facility, will cause poisoning and the generation of security incident such as blast as existing to leak.
The flue gas ash removal scheme generally can be divided into two kinds of dry method and wet methods, and dry method dust comprises several kinds of inertial separation dedustings, electrostatic precipitation, bag-type dust; Wet dedusting is mainly modes such as venturi water film dedusting, water scrubber.
According to the characteristics of calcium carbide tail gas, as above wet dedusting, can have following problem: efficiency of dust collection is low, can only guarantee generally speaking about 95%, produces influential to the back operation; Be rich in tar, part heavy metal, cyanide etc. in the waste water, be difficult to handle and cause the secondary pollution of waste water, waste residue; Smoke moisture after the processing is big, adds that dust can not all be removed, and it is serious to cause conveyance conduit and back operation gas equipment to stop up, and influences the normal operation of equipment.
In the dry method dust, electrostatic precipitation can produce electrostatic spark, seriously leaks out as existing in the system, and oxygen concentration surpasses more than 1%, serious accident such as very likely blast, and bag-type dust safety is controlled, but efficiency of dust collection still has much room for improvement.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of the utility model is to provide a kind of calcium carbide stove exhaust treating apparatus, and dedusting safety is controlled, and has improved efficient.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of calcium carbide stove exhaust treating apparatus; Comprise inlet box 4, inlet box 4 is communicated to the bag-type dust district that is furnished with a plurality of cloth bags 5, and inlet box 4 has a plurality of baffle plates 3 with the connecting pipe set inside in bag-type dust district; Two adjacent baffle plates interlaced arrangement about in the of 3; Form the flap route of tail gas, the below, flap zone that a plurality of baffle plates 3 form is communicated with elementary collection ash storehouse 1, and below, bag-type dust district is communicated with secondary collection ash storehouse 2.
Aspect ratio cloth bag 5 height of said baffle plate 3.
Compared with prior art, the utility model has the advantages that:
1) dust removal process safety can not produce electric spark, causes a hidden trouble;
2) efficiency of dust collection is high, through the flap zone is set, reduces the speed that tail gas gets into the bag-type dust district, makes the bigger flue dust of particle diameter promptly precipitate in the flap zone, has effectively improved the efficient of dedusting.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
Shown in accompanying drawing, the utility model is a kind of calcium carbide stove exhaust treating apparatus, comprises inlet box 4; Inlet box 4 is communicated to the bag-type dust district that is furnished with a plurality of cloth bags 5; Inlet box 4 has a plurality of baffle plates 3 with the connecting pipe set inside in bag-type dust district, and the aspect ratio cloth bag 5 of baffle plate 3 wants high, can guarantee cloth bag 5 is blocked; Two adjacent baffle plates interlaced arrangement about in the of 3; Form the flap route of tail gas, the below, flap zone that a plurality of baffle plates 3 form is communicated with elementary collection ash storehouse 1, and below, bag-type dust district is communicated with secondary collection ash storehouse 2.
The course of work of the utility model is such:
Calcium carbide stove exhaust enters into the flap zone from inlet box 4, and through repeatedly turning back, air inlet speed reduces gradually; The flue dust that particle diameter is bigger then slowly precipitates, and drops in the elementary collection ash storehouse 1 of bottom, flap zone, and the tail gas through elementary deposition enters into the bag-type dust district then; This moment, the speed of tail gas was lower, and thick flue dust is removed, so under the effect of cloth bag 5; Remaining tiny flue dust is removed very soon, and the flue dust of removal falls into the secondary collection ash storehouse 2 of bottom, bag-type dust district.
The preferred embodiment of more than introducing that only is based on the utility model can not limit the scope of the utility model with this.Any the utility model is done replacement, combination, the separation of parts well know in the art, and the utility model implementation step is done that well know in the art being equal to changes or replacement does not all exceed the protection domain of the utility model.
Claims (2)
1. a calcium carbide stove exhaust treating apparatus comprises inlet box (4), and inlet box (4) is communicated to the bag-type dust district that is furnished with a plurality of cloth bags (5); It is characterized in that; Inlet box (4) has a plurality of baffle plates (3) with the connecting pipe set inside in bag-type dust district, and adjacent two baffle plates (3) are interlaced arrangement up and down, forms the flap route of tail gas; The below, flap zone that a plurality of baffle plates (3) form is communicated with elementary collection ash storehouse (1), and below, bag-type dust district is communicated with secondary collection ash storehouse (2).
