Abstract
The utility model discloses a kind of circulating hydrogen fluoride wash device, belong to chemical technology field, be related to the scrubbing tower heat sink in hydrogen fluoride production technique, solve the technical problems such as existing hydrogen fluoride production scrubbing tower cooling-down effect is bad and scrubbing tower dust removing effects are not good.The circulating hydrogen fluoride wash device of the utility model, including Xian Dita, the Xian Di tops of tower are provided with distributor, centre and are provided with packing layer, and it also includes the circulatory system being made up of pipeline, magnetic drive pump, switch valve, and the magnetic drive pump is driven by variable-frequency motor.Because the utility model is mounted with a set of EGR, cleaning solution forms certain pressure in conveyance conduit, thus cleaning dust ability can improve, while circulating cooling efficiency is also lifted, so as to effectively reach high-effective dust-removing with cooling purpose.
Description
Technical field
The utility model is related to a kind of hydrogen fluoride production technique scrubbing tower EGR, it is adaptable in hydrogen fluoride production technique
Scrubbing tower heat sink.
Background technology
In traditional hydrogen fluoride production technique, the main heavy constituent mixed acid by rectifying tower reactor bottom of the cleaning solution of scrubbing tower,
Partial reflux condensation acid and sulfuric acid absorption tower at first cold pipe are made up of the sulfuric acid that high-low-position drop is flowed into, by for a long time
Research find that this washing process also exists in terms of dedusting, cooling and returned in considerable room for improvement, particularly reaction converter
After the installation of slag mechanism, production capacity lifting 20%, that is, the rough hydrogen fluoride gas flow for producing increases by 20%, it is clear that original washing
Deethanizer design specification has been difficult to meet increased cooling load of dust remove, so that increase the gaseous crude hydrogen fluoride for producing being directly entered
During last part technology is first-stage condenser and secondary condenser, so as to increased the cooling load of this part.Existing refrigerant compression
Acc power cannot meet the cooling load for exceeding, thus gaseous hydrogen fluoride can be caused to be directly discharged into process tail gas absorption system
In, entered in air eventually through smokestack.Obviously, above-mentioned condition can cause the increased gas production of institute to be wasted because not absorbing,
The treatment cost of handling process tail gas can also be increased simultaneously.Further, since scrubbing tower dust removing effects are not good, sucked during feeding intake
Dust accumulated over a long period in filler and cause process system Negative Pressure Difference of depositing, it is necessary to often to scrubbing tower to carry out technique clear for parking
It is stifled, influence the continual and steady operation of production.
Utility model content
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided a kind of circulating hydrogen fluoride wash dress
Put, improve the detersive efficiency of hydrogen fluoride wash tower, increase cooling-down effect, equipment operation is more steady.
To achieve the above object, the utility model is adopted the following technical scheme that：
Circulating hydrogen fluoride wash device, including Xian Dita, the Xian Di tops of tower are provided with distributor, centre and are provided with filler
Layer, it also includes the circulatory system being made up of pipeline, magnetic drive pump, switch valve, and the magnetic drive pump is driven by variable-frequency motor.
Pipeline inside lining teflon material, can so improve pipeline corrosion resistance.
Because traditional wash mill does not have ad hoc wash cycle mechanism, its cleaning solution is passed through by rectifying tower reactor bottom
The sulfuric acid of the intermittent conveying of measuring pump, the thick acid in part and sulfuric acid absorption tower that are condensed from first device for cooling are fallen by high-low-position
The sulfuric acid unification that difference is flowed into is flowed in scrubber overhead portion distributor, and its flow velocity and flow are less, also uncontrollable, therefore washing effect
Really bad, hydrogen fluoride gas cooling-down effect is bad.Now increase corrosion resistant magnetic force circulating pump by wash tower bottoms, it is and related
Pipe fitting valve is connected and constitutes the circulation washing device of complete set, while being turned by installing Frequency Converter Control magnetic force pump motor
Speed, can wash the frequency according to being actually needed control flow and circulating.Squeezed into by magnetic drive pump from the nitration mixture liquid of wash tower bottoms
To washing scrubbing tower at the top of distributor layer, through distributor be flowed into each section of tower body packing layer and with rise rough hydrogen fluoride
Gas is sufficiently mixed, and the thick acid under condensation flows ultimately into wash tower bottoms, then is driven into scrubbing tower top through circulating pump, above-mentioned
Processing step is continuous repetitive cycling, thus constitutes the cooling-cycle device of complete set.Because the thick acid of liquid is by magnetic drive pump
Conveying, forms certain pressure in conveyance conduit, thus cleaning dust ability can improve, while circulating cooling efficiency is also carried
Rise, so as to effectively reach high-effective dust-removing with cooling purpose.

Specific embodiment
As shown in figure 1, in traditional hydrogen fluoride wash production technology, the cleaning solution of scrubbing tower is main by the bottom of rectifying tower reactor 1
Heavy constituent mixed acid, the sulfuric acid that is flowed into by high-low-position drop of sulfuric acid absorption tower 2 and thick from the part of first device for cooling condensation
Acid unification is flowed to scrubbing tower top, and generation cleaning function is flowed down from current divider.The circulating hydrogen fluoride wash dress of the utility model
Put, including Xian Di towers 3, it is provided with distributor 3.1, centre at the top of the Xian Di towers 3 and is provided with packing layer 3.2, it also includes by pipeline
4th, magnetic drive pump 5, the circulatory system of the composition of switch valve 6, the magnetic drive pump 5 are driven by variable-frequency motor, can be according to being actually needed control
Flow processed and the circulation washing frequency, the inside lining teflon material of the pipeline 4 play corrosion-resistant effect.
After EGR is installed, washing scrubbing tower 3 is driven into by magnetic drive pump 5 from the nitration mixture liquid of the bottom of scrubbing tower 3 and is pushed up
The distributor 3.1 in portion, through distributor be flowed into each section of tower body packing layer 3.2 and with rise rough hydrogen fluoride gas fully mix
Close, the thick acid under condensation flows ultimately into the bottom of scrubbing tower 3, then is driven into the top of scrubbing tower 3, above-mentioned technique step through magnetic drive pump 5
Suddenly it is continuous repetitive cycling, thus constitutes the cooling-cycle device of complete set.Because the thick acid of liquid is by the conveying of magnetic drive pump 5,
Certain pressure is formed in conveyance conduit, thus cleaning dust ability can be improved, while circulating cooling efficiency is also lifted, so that
High-effective dust-removing is effectively reached with cooling purpose.Determined according to actual motion, 3~5 DEG C of scrubber system temperature overall reduction is alleviated
The load of back segment refrigeration operation；Former scrubbing tower need to stop for average 90 days or so carries out technique cleaning dedusting, nearly 1 year of existing even running
Do not occur silting phenomenon also, greatly improve equipment continuous service ability.
