Abstract

The utility model relates to a calcium carbide furnace tail gas mixing purification system utilizing bag dedusting. A calcium carbide furnace tail gas pipe is respectively communicated with a first dust outlet device and a cyclone dust collector through a cooler, the cyclone dust collector is communicated with a filter through a primary air fan, the filter is communicated to a gas kiln through a secondary air fan and a booster fan, and meanwhile the filter is communicated to a second dust outlet device. Compared with the prior art, the calcium carbide furnace tail gas mixing purification system integrates cyclone dedusting with air bag dedusting, so tail gas dedusting treatment effect is effectively improved. Dust filtered by the purification system is conveyed and treated in a centralized manner, and accordingly secondary dust raising and pollution are avoided, the problem of calcium carbide furnace tail gas pollution is thoroughly solved, and economic benefit is evident.

Description

A kind of hybrid cleaning system of calcium carbide stove exhaust of utilizing bag-type dust
Technical field
The utility model belongs to chemical machinery field, more specifically provides a kind of hybrid cleaning system of calcium carbide stove exhaust of utilizing bag-type dust.
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 hybrid cleaning system of calcium carbide stove exhaust of utilizing bag-type dust, has good dedusting effect, and reaction efficiency is high, recycles easy characteristics.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of hybrid cleaning system of calcium carbide stove exhaust of utilizing bag-type dust; Calcium carbide stove exhaust pipe 1 is communicated with first ash discharging gear 5 and cyclone dust collectors 3 respectively after being communicated with cooler 2; Cyclone dust collectors 3 are communicated with filter 6 via primary air fan 4 again; Filter 6 is communicated to gas burning kiln 9 behind overfire air fan 7 and booster fan 10, filter 6 is communicated to second ash discharging gear 8 simultaneously.
Compared with prior art, the gentle bag filtration of the comprehensive cyclone dust removal of native system has effectively improved the effect that tails dedusting is handled, and the dust under cleaning system is filtered is concentrated transport process, avoids reentrainment of dust and pollution; Thoroughly solved the calcium carbide stove exhaust pollution problem, economic benefit is obvious.
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 hybrid cleaning system of calcium carbide stove exhaust of utilizing bag-type dust; Calcium carbide stove exhaust pipe 1 is communicated with first ash discharging gear 5 and cyclone dust collectors 3 respectively after being communicated with cooler 2, and cyclone dust collectors 3 are communicated with filter 6 via primary air fan 4 again, and filter 6 is a cloth envelop collector; Filter 6 is communicated to gas burning kiln 9 behind overfire air fan 7 and booster fan 10, filter 6 is communicated to second ash discharging gear 8 simultaneously.
The course of work of the utility model is following:
Calcium carbide stove exhaust gets into cyclone dust collectors 3 one-time dedustings from calcium carbide stove exhaust pipe 1 after cooler 2 coolings; Filter through filter 6 again; Gas after the filtration is delivered to booster station through the pure qi (oxygen) blower fan; After booster fan is with the required pressure of gas boosting to gas burning lime kiln, get into the gas burning lime kiln burning again, excess gas can be discharged through the chimney of releasing.Dust under whirlwind air cooling deduster and cloth envelop collector filter is delivered to the total storehouse of dust by sealed chain mat machine.The pressure release of whole system, the explosion-proof computer controlled automatic that all adopts; System is provided with several switching points; As: the filter inlet temperature is high, filter pressure difference is too high; The high signal that jeopardizes the equipment personal safety of oxygen content in the gas, computer cut off cleaning system at once, gas are discharged from the Primordial Qi pipeline etc.
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.
