Abstract
A thermostatic bag dust collector belongs to the technical field of gas-solid separation equipment in chemical industry production. The dust collector comprises that two dust-collector drums having built-in filter bag with same structure and same function are communicated with each other by air inlet pipe and air outlet pipe, valves are arranged on air inlet pipe and air outlet pipe, under the dust collector drums , dust collection chamber and dust collection bucket are mounted, which communicate with each other by valve pipe, and valves are mounted on the inlet pipe and outlet pipe of dust collection chamber respectively, and heating and thermal-insulating facilities are also arranged on the dust collector drums, air inlet pipe, air outlet pipe, valves, dust collection chamber, and dust collection bucket. The invention is provided by high separation and removal efficiency of dust, and as a result, the environment pollution problem is solved.
Description
Technical field
The invention belongs to the gas-solid separation equipment technical field in the Chemical Manufacture, specially refer to a kind of constant-temperature bag type dust collector, be applicable to the gas of industries such as chemical industry, metallurgy, pharmacy, solid detached job.
Background technology
In modern chemical industry is produced, usually be under higher temperature conditions, to carry out.Just under the above temperature of certain chemical material cloud point, separate the operation of gas phase, solid-phase material.For example in the titanic chloride production process, because the boiling point of titanium tetrachloride is 136 ℃, high-temp chlorination has produced and has contained TiCl in chlorination furnace
4, CO, CO
2, petroleum coke powder, TiO
2, FeCl
3, AlCl
3, MnCl
2Flue gas etc. multiple composition.How can the solid phase composition in the flue gas be separated from gas phase, admittedly contained the gas of fewer titanium tetrachloride, be the key of chloride operation.The dust-collecting efficiency that is mostly that uses is 80～90% decanter type deduster or cyclone dust collectors at present.Bag filter is to develop cleaner faster in recent years, and bag filtering material serviceability temperature and decay resistance are all constantly improving.If but at TiCl
4The following filtering gas of cloud point will make TiCl
4Be condensed into liquid, titanium tetrachloride blocks the filter bag hole, filtration resistance is strengthened, and can't produce.If use the very low deduster of efficiency of dust collection, the solid material in the flue gas is removed unclean, causes the post-order process overload, gleanings difficult treatment, a series of problems such as environmental pollution is serious.
Summary of the invention
In order to solve the problem of above-mentioned existence, the object of the present invention is to provide a kind of constant-temperature bag type dust collector, it is in the temperature range of being controlled, and separates the chemical production equipment of gas, solid phase object.
Structure of the present invention, comprise two dedusting buckets that 26S Proteasome Structure and Function is identical, the dedusting bucket is built-in with filter bag, be connected with escape pipe by air inlet pipe respectively between two barrels, on air inlet pipe and escape pipe, be provided with valve, grey storehouse of collection and flue-dust retainer are installed below the dedusting bucket, collecting grey storehouse is connected by valve pipeline with flue-dust retainer, be separately installed with valve I and valve II on the turnover pipe in the grey storehouse of collection, two dedusting buckets, air inlet pipe, escape pipe, valve, collection ash storehouse and flue-dust retainer all are equipped with heating and lagging facility.One of them dedusting bucket is in running order, and another dedusting bucket is in the duty of cleaning filter bag, and the duty of two dedusting buckets is controlled by valve on tracheae.Before the needs work therein of two dedusting buckets, will heat it, make it to be in constant under a temperature, the temperature that undulating value need be controlled ± 10～20 ℃ scope, the cloud point of gaseous substance when this control temperature depends on gas phase separation.
The mode of heating of heating and lagging facility is that resistance companion heat heats or the heating agent heater heats or hot blast heats multiple mode, working media of handling according to deduster and environment for use decide and adopt which kind of mode of heating, lagging facility is that skin at heater is equipped with insulation material.
Filter bag purge mode of the present invention adopts blow-back formula, mechanical-vibration type and the multiple mode of ultrasonic wave deashing, according to the different different modes that use of dedusting working media and condition of work.If use reverse gas cleaning, meet airborne steam in order to prevent the dedusting working media in the blowback process, or the purge gas temperature is low excessively, cause problems such as filter medium gas cooling chemically reactive, the working media gas that does not contain dust after employing nitrogen or dry air or the dedusting comes deashing as purge gas, and will heat purge gas.Outside, for more valuable or with the working media gas that pollutes that water in air part can react, quitting work, needing when repairing filter bag in the dedusting bucket, charge into inert gas.
Flue-dust retainer also need keep temperature constant state, to guarantee to collect solid formation few gaseous working medium of trying one's best.Employing charges into the mode of inert gas, the gas phase component of the working media that extruding is wrapped gets off to flue-dust retainer inside from solid formation.And flue-dust retainer bottom ash-valve employing dual-valve structure, double valve is separated, and different time sections is open, with the locked and isolated gas that is reduced the outside that spills gas or be inhaled into by external system.
The section configuration that filter bag is housed in dedusting bucket inside can be circle also can be diamond pattern, can be that what to add bracing frame also can be not add supporting bracket, the gas speed of dust removal by filtration is 0.4～2.0m/min.
A series of problems such as advantage of the present invention is that feed separation, removing are effective, alleviates the load of post-order process, has solved the gleanings difficult treatment, and environmental pollution is serious.
