Description
Technical field
The utility model relates to a kind of spray-type sulphur ammonium saturex of coking industry.
Background technology
The thiamine process of the coke-oven plant that China now moves is mainly made absorption agent with sulfuric acid, removes the ammonia in coal gas, makes the ammonia mass concentration in coal gas drop to 50mg/m
3below, generate sulphur ammonium simultaneously, after being dried, obtain ammonium sulfate products.
Coke-oven plant in the market and the deamination of producing synthesis gas from coal are to carry out in spray-type sulphur ammonium saturex substantially, this class saturex is comprised of chamber under chamber in taper and tubular conventionally, gas inlet is positioned at the sidewall of chamber, drawing coal gas indoorly contacts with the sulfate liquor spraying out upper, make the ammonia in coal gas enter into sulfate liquor generation sulphur ammonium, the coal gas after de-ammonium is discharged by top.There is more problem in traditional spray-type sulphur ammonium saturex.Because the sidewall in upper chamber is set up in gas inlet, exist air inlet inhomogeneous on the one hand, cause contacting inhomogeneous problem with sulfate liquor, affect deamination rate; On the other hand, the sulfate liquor spraying out easily backflows through gas entry, before spray-type sulphur ammonium saturex, connect gas preheater, thereby the sulfate liquor backflowing very easily corrodes gas preheater, cause the problems such as service life of equipment declines, the shut-down of repeatedly overhauling, stop production to occur.In addition, due to coal gas and liquid mixing, be very easily with liquid in uphill process, affect normally carrying out of subsequent handling, this is also the problem that technician need to solve.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, provide a kind of simple in structure, long service life, coal gas deamination effective, reduce the spray-type sulphur ammonium saturex that etching problem occurs, assurance system is moved reliably and with long-term.
Technical scheme comprises chamber in the taper that is provided with gas inlet, gas exit and is provided with chamber under the tubular of sulphur crystalline ammonium outlet, in described taper, chamber is communicated with chamber under tubular through downtake, in described taper, chamber epimere medullary ray is provided with the gas up take communicating with gas exit, stage casing is provided with sulfate liquor shower, on the medullary ray of described gas up take, be also provided with coal gas bend pipe, the entrance of described coal gas bend pipe is communicated with gas inlet, and outlet is positioned at the below of sulfate liquor shower.
Described sulfate liquor shower is connected with the circulating mother liquor outlet of chamber under tubular through recycle pump.
The entrance of described coal gas bend pipe arranges staggered polylith baffle plate, and the outlet of coal gas bend pipe is the more than 1/5 of chamber total height in taper apart from the difference of altitude of thioesters mother liquor shower.
The exit of described gas up take is provided with wire mesh demister.
Described gas up take is provided with toroidal membrane outward.
The position of described gas inlet is higher than sulfate liquor shower, and sulfate liquor shower top is also provided with spiral board.
In described taper, annular fluid infusion shower is also established at top, chamber.
Contriver, by coal gas bend pipe is set, avoids sulfate liquor directly to enter in gas pipe, thereby avoids passing back in gas preheater, the corrosion that can effectively avoid sulfate liquor to reflux to gas preheater; Make the outlet of coal gas bend pipe be positioned at the below of sulfate liquor shower, enter so reverse contact of sulfate liquor that indoor coal gas can spray with top, because coal gas bend pipe is positioned at gas up take and taper mistress's position of center line, the coal gas of drawing is like this more even at indoor distribution, further improves deamination effect.Described coal gas bend pipe entrance arranges staggered polylith baffle plate to avoid sulfate liquor to be backflowed into gas inlet by coal gas bend pipe, coal gas winding pipe exit is preferably the more than 1/5 of chamber total height in taper apart from the difference of altitude of thioesters mother liquor shower simultaneously, to guarantee coal gas and the abundant counter current contact of sulfate liquor, strengthening assimilation effect, also has the effect that prevents that sulfate liquor from backflowing.
Further, at described upcast, being provided with toroidal membrane outward can effectively avoid sulfate liquor backflow to cause corrosion to gas preheater, can make that coal gas is indoor in taper is folded to motion several times, effectively reduce coal gas and carry secretly, alleviate obstruction and the corrosion of export coal feed channel.
Further, wire mesh demister and spiral board being set, is also in order effectively to prevent or to reduce coal gas carrying liquid, also improved sulphur ammonium productive rate in ammonia content in reducing coal gas.
The utility model can effectively prevent or reduce coal gas carrying liquid, can effectively avoid sulfate liquor to reflux gas preheater is caused to corrosion, have that coal gas system resistance is little, crystalline particle is large, sulphur ammonium quality is good, an easy handling, the beneficial effect such as service life of equipment operating rate long, operation is high and running cost is low.In the deamination system of the utility model Ke coke-oven plant or gas producing device, carry out, the ammonia in coal gas is fully removed to recovery, remove ammonia effective.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, chamber, the outlet of 8.1-circulating mother liquor, the outlet of 8.2-sulphur crystalline ammonium, 9-downtake, 10-gas up take under chamber, 7.1-gas inlet, 7.2-gas exit, 7.3-fluid infusion shower, 8-tubular in 1-wire mesh demister, 2-toroidal membrane, 3-coal gas bend pipe, 3.1-baffle plate, 4-spiral board, 5-sulfate liquor shower, 6-recycle pump, 7-taper.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further explained to explanation: the utility model comprises the upper chamber 7 of taper and is provided with the lower chamber 8 of the tubular of sulphur crystalline ammonium outlet, in described taper, chamber 7 is communicated with chamber under tubular 8 through downtake 9, in described taper, chamber 7 sidewalls are established gas inlet 7.1, top is provided with the fluid infusion shower 7.3 of gas exit 7.2 and annular setting, in described taper, on the epimere medullary ray of chamber 7, be also provided with the gas up take 10 being communicated with gas exit 7.2, coal gas after deamination is discharged through gas exit 7.2 by gas up take 10, stage casing is evenly provided with a plurality of sulfate liquor showers 5, the exit of described gas up take 10 is provided with wire mesh demister 1 and is with liquid to reduce in the coal gas of discharging, and the outer toroidal membrane 2 that is provided with of described gas up take 10 causes corrosion effectively to avoid sulfate liquor to reflux to gas preheater.On the medullary ray of described gas up take 10, be also provided with coal gas bend pipe 3, the entrance of described coal gas bend pipe 3 is communicated with gas inlet 7.1, and entrance arranges staggered polylith baffle plate 3.1, and the outlet that coal gas bend pipe 3 is vertical is positioned at the below of sulfate liquor shower 5.Described a plurality of sulfate liquor shower 5 is connected with the circulating mother liquor outlet 8.1 of chamber under tubular 8 through recycle pump.The outlet of described coal gas bend pipe 3 is apart from the more than 1/5 of chamber 7 total heights in the taper of thioesters mother liquor shower 5; The position of described gas inlet 7.1 is higher than sulfate liquor shower 5, and sulfate liquor shower 5 tops are also provided with spiral board 4.
