Description
Technical field
The utility model relates to the technical field of waste heat recovery in Chemical Manufacture, particularly relates to the diluter that in the sulfur trioxide absorption process of sulfuric acid production process, high-temperature concentrated sulfuric acid mixes with water.
Background technology
In the absorption process of the sulfur trioxide gas of sulfuric acid apparatus, industrial production adopts the vitriol oil to absorb the sulphur trioxide in gas, and then to absorb after concentration increase the vitriol oil in add water maintain required for acid dense.
Traditional sulfuric acid production process is employing temperature about 80 DEG C, the concentrated acid of concentration about 98% absorbs, and the acid temperature after absorption is at about 100 DEG C, and adding water in this acid is easily, does not need to realize adding water with special diluter.But the heat that traditional absorption process produces does not have utility value because recycle acid temperature is lower, can only to cool with recirculated cooling water and by this heat discharged to air.Absorb acid acid temperature if improved, just improve the utility value of this heat.According to the requirement of absorption technique, also need suitably to improve to absorb acid concentration while raising absorbs acid acid temperature.When the gentle acid of absorption acid acid of the heat recovery system adopted is dense be 220 DEG C and about 99% time, under this sour temperature, sour dense its corrodibility of subtle change will vary widely.Therefore, in heat recovering process, the homogeneity the added water consistence that namely acid is dense is most important.
The diluter that the acid of existing employing as a kind of sulfuric acid apparatus of CN201404776Y mixes with water, but because when reality uses, equipment volume is comparatively huge, inevitable generation comparatively big bang, some impacts are produced for production, so, be necessary further improve and optimize the diluter structure added water in hot acid.
Utility model content
The object of the invention is to guarantee the uniformity consistency that after adding water, acid is dense, by the corrosion control of high-temperature sulfuric acid alloy equipment in certain scope, thus enable the low-temperature level of sulfuric acid apparatus heat recovery system pick up the heat technique of giving up realize industrialization, the heat recovery and utilization of the sulfuric acid absorption system originally taken away by recirculated water is produced steam, reaches the object that waste heat recovery utilizes.
The technical scheme that the utility model adopts is:
The diluter that a kind of acid of sulfuric acid apparatus mixes with water, its feature is, it comprise water and air import and add sprinkler head, recycle acid import, sour water mixing section and recycle acid outlet, between recycle acid import and sour water mixing section and recycle acid export between sour water mixing section with Flange joint.
In heat recovering process, this diluter is arranged on the downstream of thimble-tube boiler, and add water in the acid of thimble-tube boiler outlet, the acid after thin up returns heat recovery tower and circulates.
Further, this diluter is U-shaped structure, take polytetrafluoroethylmaterial material as the stainless steel equipment of lining.Equipment directly connects with basis and considers thermal expansion effects, effectively reduces vibrations.
Further, the sour water mixing section of this diluter connects with elbow, elbow respectively with acid inlet tube, go out acid tube connect.Water adds sprinkler head by one and adds from the mixing section of this diluter, the water and air import of this diluter and add the pipe that sprinkler head is a kind of porous.What air (can be factory's wind, instrument air or other air) was also added to this horizontal section adds water end (W.E.) to improve the mixed performance of hot acid and water.
Below in conjunction with accompanying drawing, the utility model is elaborated.
Accompanying drawing explanation
Figure l is the structural representation of embodiment of the present utility model.
In figure: 1-water and air import and add sprinkler head; 2-sour water mixing section; The import of 3-recycle acid; 4 one recycle acid outlets.
Embodiment
Below in conjunction with embodiment, the utility model is described further.
EXAMPLE l
The diluter that a kind of acid of sulfuric acid apparatus mixes with water, the equipment that a kind of hot acid mixes with water, it comprise water and air import and add sprinkler head l, recycle acid import 3, sour water mixing section 2 and recycle acid outlet 4, between recycle acid import and sour water mixing section and recycle acid export between sour water mixing section with Flange joint.This diluter is " U " type structure, and it is the multi-stage type stainless steel equipment of a kind of band polytetrafluoroethylmaterial material (Teflon Teflon) or other material lining.Recycle acid adds from an elbow and flows out from another elbow.
Water adds sprinkler head 1 by one and adds sour water mixing section, and this adds sprinkler head is a kind of pipe with porous.What air (can be factory's wind, instrument air or other air) was also added to this horizontal section adds water end (W.E.) to improve the mixed performance of hot acid and water.
Sulphur-burning sulphuric acid plant with heat recovery system diluter is about 1000m
3/ h, temperature are entered to say from acid at the recycle acid of about 200 DEG C and are entered, about 10m
3/ h, temperature add from filler at the hot water of about 110 DEG C, can have 200m
3the drying tower recycle acid of/below h is added in this diluter, and according to the actual needs of process system, the add-on of factory air depends on mixed effect, and flow is at 100m
3/ below h.
Adopt diluter of the present utility model, the uniformity consistency that after adding water, acid is dense can be guaranteed, by the corrosion control of high-temperature sulfuric acid alloy equipment in certain scope, thus enable the low-temperature level of sulfuric acid apparatus heat recovery system pick up the heat technique of giving up realize industrialization, the heat recovery and utilization of the sulfuric acid absorption system originally taken away by recirculated water is produced steam, reaches the object that waste heat recovery utilizes.
Although above-mentioned specific embodiment describes the utility model, this description does not mean that and is construed as limiting.After with reference to description of the present utility model, for person skilled in the art, obviously various correction can be made to the disclosed embodiments.Various similar correction all falls within right of the present utility model.
