Description
Technical field
The utility model belongs to chemical machinery field, more specifically provides a kind of calcium carbide stove exhaust total system.
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 total system, 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 total system comprises inlet box 4, and inlet box 4 is communicated with the cooling zone that is furnished with cooler 7; The cooling zone is communicated with the electrostatic precipitation district that is furnished with electrostatic precipitator 3; The electrostatic precipitation district is communicated with the bag-type dust district that is furnished with cloth bag 5, between electrostatic precipitation district and the bag-type dust district baffle plate 6 is arranged, and the upper end of baffle plate 6 is fixed; The lower end is unsettled; Make tail gas from the space, lower end, get into the bag-type dust district by the electrostatic precipitation district, the below in electrostatic precipitation district is communicated with elementary dust compartment 1, and the below in bag-type dust district is communicated with secondary dust compartment 2.
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, and with electrostatic precipitation and bag-type dust comprehensive utilization, cooled tail gas has reduced the generation probability of electrostatic spark, and baffle plate makes electrostatic precipitation district and bag-type dust district effectively separate, and the electrostatic precipitation district is isolated, and has stopped condition of a fire hidden danger basically.
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 total system, comprises inlet box 4; Inlet box 4 is communicated with the cooling zone that is furnished with cooler 7, and the cooling zone is communicated with the electrostatic precipitation district that is furnished with electrostatic precipitator 3, and the electrostatic precipitation district is communicated with the bag-type dust district that is furnished with cloth bag 5; Between electrostatic precipitation district and the bag-type dust district baffle plate 6 is arranged; The upper end of baffle plate 6 is fixed, and the lower end is unsettled, makes tail gas from the space, lower end, get into the bag-type dust district by the electrostatic precipitation district; The below in electrostatic precipitation district is communicated with elementary dust compartment 1, and the below in bag-type dust district is communicated with secondary dust compartment 2.
The course of work of the utility model is such:
Calcium carbide stove exhaust enters into the cooling zone from inlet box 4, under the effect of cooler 7, is cooled, and cooled tail gas enters into the electrostatic precipitation district; Flue dust a large amount of under the effect of electrostatic precipitator 3 are processed, and the flue dust after the processing slowly precipitates, and drop in the elementary dust compartment 1 of bottom, flap zone; Tail gas through elementary dedusting slowly enters into the bag-type dust district from the space of baffle plate 6 belows 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 dust compartment 2 of bottom, bag-type dust district.
Because the effect of cooling, the tail gas in the electrostatic precipitation district has reduced the generation probability of electrostatic spark, and because baffle plate is isolated electrostatic precipitation district and bag-type dust district with the electrostatic precipitation district effective the separation basically, has effectively stopped condition of a fire hidden danger.
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.
