Background technology
Existing propyl trimethoxy silicane production technology is to be made by propyltrichlorosilan rectifying after the methyl alcohol alcoholysis, and in alcoholysis process, can produce a large amount of accessory substances, and hydrogen chloride gas causes cost height, with serious pollution problem.Therefore; In order to reduce cost and to reduce pollution to environment, introduced falling-film absorber hydrogen chloride gas has been processed the hydrochloric acid byproduct of high concentration, but in the byproduct hydrogen chloride gas that in actual production, produces; Can carry a spot of propyl trimethoxy silicane material steam secretly; These material steams can hydrolysis form thick solid in falling-film absorber, thereby can stop up falling-film absorber, have not only increased the burden of water scrubber thus; But also reduced the concentration and the falling-film absorber treatment effeciency of byproduct hydrochloric acid, can not the high problem of workout cost.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, a kind of prevent to stop up, the improve absorption strength of hydrochloric acid, the falling film absorption device of raising falling-film absorber treatment effeciency are provided.
The utility model solves the technical scheme that its technical problem adopted: this kind falling film absorption device; Comprise that internal vertical is provided with the falling-film absorber of many tubulations; It is characterized in that: falling-film absorber and water scrubber and the hydrochloric acid circulating slot formation closed circuit that links; Falling-film absorber top attachment air shooter, top one side connects water scrubber through the diluted acid carrier pipe, and the bottom connects the hydrochloric acid circulating slot; Bottom one side connects water scrubber through the material letter shoot, and the hydrochloric acid circulating slot other end connects hydrochloric acid tank and diluted acid carrier pipe respectively through pump and concentrated hydrochloric acid transfer pipeline.Gas (and stream) from top to bottom passes through interior tube space; Gas-liquid two-phase carries out mass transfer reaction on the liquid film that flows; Tubulation feeds cooling water (agent) through the cooling water upper hose outward in falling-film absorber, to remove the heat that discharges in the absorption process, reduce the burden of water scrubber.
Described falling-film absorber top one side connects CWR, and bottom one side connects the cooling water upper hose.Through cooling water or cooling agent tubulation is cooled off, lowers the temperature repeatedly.
The outlet at described water scrubber top connects caustic wash tower through pipeline.
Compared with prior art, the beneficial effect that the utility model had is:
1, effectively prevents to stop up; Solved in the propyl trimethoxy silicane production process, the material steam in the falling-film absorber stops up the difficult problem of falling-film absorber, has effectively reduced the burden of water scrubber; Solve the high problem of cost completely, reduced production cost significantly.
When 2, solving blockage problem, also improved the concentration of byproduct hydrochloric acid, improved the falling-film absorber treatment effeciency, further reduced production cost, and prolonged the service life of equipment.
Description of drawings
Fig. 1 is the utility model structure annexation sketch map.
Wherein: 1, hydrochloric acid tank 2, air shooter 3, CWR 4, falling-film absorber 5, cooling water upper hose 6, diluted acid carrier pipe 7, efferent duct 8, flow pipe 9, water scrubber 10, material letter shoot 11, hydrochloric acid circulating slot 12, pump.
Fig. 1 is the most preferred embodiment of the utility model, further specifies below in conjunction with 1 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1:
This kind falling film absorption device mainly is made up of falling-film absorber 4, cooling water upper hose 5, diluted acid carrier pipe 6, efferent duct 7, flow pipe 8, water scrubber 9, material letter shoot 10, hydrochloric acid circulating slot 11 and pump 12 that hydrochloric acid tank 1, air shooter 2, CWR 3, internal vertical are provided with many tubulations.Falling-film absorber 4 and water scrubber 9 and the hydrochloric acid circulating slot 11 formation closed circuit that links; Falling-film absorber 4 top attachment air shooters 2; Feed hydrogen chloride and material gas in the air shooter 2; Falling-film absorber 4 tops one side connects water scrubber 9 bottoms through diluted acid carrier pipe 6, and falling-film absorber 4 tops one side connects CWR 3, and bottom one side connects cooling water upper hose 5; Falling-film absorber 4 bottoms connect hydrochloric acid circulating slot 11, and bottom one side connects water scrubber 9 bottoms one side through material letter shoot 10, and the outlet at water scrubber 9 tops connects caustic wash tower through pipeline.Hydrochloric acid circulating slot 11 other ends connect pump 12 and concentrated hydrochloric acid transfer pipeline, and the concentrated hydrochloric acid transfer pipeline is divided into two-way, connect hydrochloric acid tank 1 and diluted acid carrier pipe 6 respectively.
The course of work is following:
The utility model is when work, and absorbent vertically descends with film like along the tubulation inwall in the falling-film absorber 4 through filming device, and gas (and stream) from top to bottom passes through interior tube space; Gas-liquid two-phase carries out mass transfer reaction on the liquid film that flows, tubulation feeds cooling water (agent) through cooling water upper hose 5 outward in falling-film absorber 4, to remove the heat that discharges in the absorption process; The consumption of cooling water (agent) can carry out heat balance according to concrete operating procedure and condition to be decided, this be since gas be absorbed as the raising absorption efficiency, should reduce the absorbent temperature as far as possible; And the consumption of increase cooling water (agent) is used for reducing water temperature, helps improving absorption efficiency; Circulation absorbs; Efficient can be up to more than 98%, and the production capacity of this absorber can be adjusted in a big way, and control is convenient; Show that through experiment 10～20 tons of 31% hydrochloric acid can be produced in (24 hours) in one day.
After falling-film absorber 4 absorbs, get into hydrochloric acid circulating slot 11 from the bottom through pipeline, the concentrated sulfuric acid in the hydrochloric acid circulating slot 11 is transported in the middle of the hydrochloric acid tank 1 through pump 12.Falling-film absorber 4 absorbs material gas later and is conveyed in the water scrubber 9 through material letter shoot 10, through getting in the caustic wash tower through efferent duct 7 after the processing of water scrubber 9.
In addition, the operation of operation absorbent and absorbed gas reversible flow, but also cocurrent cooling operation, the fluid that rises during counter-current operation will cause thickness of liquid film to increase, and the liquid film flow velocity reduces, and when generally the flow velocity in gas is managed is 5～10m/s, general phenomenon can occur flowing.Gas from top to bottom flows during cocurrent cooling operation, will make the thickness of liquid film attenuate, and the liquid film flow velocity increases; And under the identical situation of gas flow rate; And the fluid resistance in when stream is much little during than adverse current, and during stream, gas speed can be up to 15～30m/s; But little when absorbing motive force than adverse current, adopt cocurrent cooling operation mostly in therefore producing at present.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
