Description
Technical field
A kind of oxidation anthraquinone production anthraquinone tail gas de-tastes dust arrester installation, belongs to oxidation anthraquinone production equipment technology.
Background technique
It is domestic that anthraquinone is generally produced with the fixed bed catalytic oxidation method that anthracene and air (utilizing wherein oxygen) are raw material,
Technique is: raw material anthracene knocks down melting pot, the liquid anthracene by collet heat-conducting oil heating to 250~260 DEG C of melting and heat preservations, after fusing
The vaporizing pot of jacketed is squeezed by submerged pump on melting pot, heat-conducting oil heating to 265~270 DEG C of heat preservations, superheated steam passes through drum
Bubble pipe makes liquid anthracene in vaporizing pot carry out quantitative vaporization, and the gaseous state anthracene after vaporization is filtered through porcelain ring filtre is sent into hot air pipe, with
A certain proportion of about 250 DEG C of hot-airs merge into mixed gas, and tangent line enters anthraquinone oxidator, i.e. fixed bed oxidator, uniformly
Carry out oxidation reaction by catalyst surface in fixed bed oxidator tube array, 350~370 DEG C of reaction gas (gaseous state anthraquinone) of generation by
Fixed bed oxidator lower head enters back into thin-walled cooling cylinder natural cooling after exporting into fire arrester, it is cold that anthraquinone crystallization is deposited in thin-walled
In solidifying case, inlet gas moves valve fixed bed oxidator is closed in parking daily when discharging before, is vented pneumatic operated valve before opening fixed bed oxidator,
It will about 250 DEG C of gaseous mixture (containing a small amount of residual anthracene dust) releases；Gone out anthraquinone squeezes through screw conveyor again and is delivered to sieve
Extension set sieving, is packed, metering, sampling analysis qualification storage；After gas goes out thin-walled cooling cylinder, room is collected through sedimentation and is further collected
Tail gas is vented after water film dedusting washs again after dust.However this release tail gas being vented after water film dedusting washs contains benzene
The dust such as acid anhydride, cis-butenedioic anhydride, naphthalene anhydride and acidic smell cause significantly to pollute to environment.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of to the release tail being vented after water film dedusting washs
The device that gas is recycled.
In order to solve the above technical problems, technical solution adopted by the utility model: a kind of oxidation anthraquinone produces anthraquinone tail
Gas de-tastes dust arrester installation, including more devices of sublimating, sedimentation collect room, circulating water pool, water circulating pump, washing absorption tower, sedimentation receipts
Collect room into offgas duct, washing absorption tower into offgas duct and outer for water pipe, the anthraquinone tail gas from thin-walled condenser successively passes through
Room is collected by sedimentation after the more devices of sublimating and enters sedimentation collection room into offgas duct, then room is collected by sedimentation and does not settle
Anthraquinone tail gas continue along washing absorption tower to enter washing absorption tower into offgas duct, the anthraquinone tail gas of the washing absorption tower is through washing
It washs absorption tower discharge nozzle and is precipitated into circulating water pool, the water circulating pump provides for the washing absorption of washing absorption tower and circulating water pool
Power, it is described outer clear water to be supplemented to washing absorption tower and circulating water pool by timing valve timing for water pipe.
The start and stop of the water circulating pump are by DCS system remote auto control.
The device of sublimating is six, and the circulating water pool is two sets.
The working process of the utility model is as follows: water circulating pump is first turned on, anthraquinone tail gas passes sequentially through 6 devices of sublimating, then
Room is collected into entering to settle, most organic acid anhydride crystallisation by cooling settle down, periodically clean up material；Minute quantity
Organic acid anhydride enters washing absorption tower with tail gas, and washed to be absorbed into tower bottom circulating water pool, 2 sets of tower bottom circulating water pools make in turn
With, periodically pull out in sedimentation basin material sunning or drying.
The utility model compared to the prior art have the advantages that by thin-walled condenser and sedimentation collect room it
Between more devices of sublimating are set, such anthraquinone tail gas enter before room is collected in sedimentation first pass sequentially through more devices of sublimating can will be exhausted
Most machine acid anhydrides crystallisation by cooling settles down, and minute quantity organic acid anhydride in addition goes successively to washing absorption tower with tail gas,
It is washed to be absorbed into tower bottom circulating water pool precipitating, so device and washing absorption tower, circulating water pool are sublimated by anthraquinone through excessive platform
Tail gas recycle avoids the pollution to environment.Simultaneously circulating water pool precipitating drying materials after with sublimate device and settle collection room it is clear
The material managed out puts into the de- brilliant carbolineum slot deallocation charcoal processing dirty oil of carbolineum process together, it is gentle to not only avoid organic acid anhydride dust
Pollution of the taste to environment, and the organic acid anhydride of a certain amount of (the 10% of yield of anthraquinone) has been recycled again as the original for preparing carbon black oil
Material, either economic benefit or Environmental Effect Yidu are apparent.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
In figure, 1 for device of sublimating, 2 be sedimentation collect room, 3 be circulating water pool, 4 be water circulating pump, 5 be washing absorption tower, 6
