Abstract
The utility model relates to a graphite modified polyacrylic falling-film absorption instrument which is an absorption instrument having the advantages of the polypropylene and the graphite, comprising a housing, an absorption section and an upper (lower) short circuit. The absorption section made of graphite modified polypropylic material, and the rest components are made of the polypropylic material, or the whole set of the instrument is made of the polypropylic material. The whole set of the instrument is corrosion-resistant, and is adapted to the occasions with high heat absorption in the chemical industry production of the medicine, the agricultural chemicals, the dye, etc., to recover the hydrogen chloride or the sulfur dioxide. The absorption area required in the absorption process is not very large, but an excellent heat transferring efficiency is required. The utility model has the advantages of high absorptance and no environmental pollution.
Description
The utility model relates to the chemical unit device of gas absorption process, being particularly related to a kind of absorption plant of following the easy molten corrosive gas of fuel factor--graphite modified polypropylene falling film absorbre is mainly used in the absorption of gases such as the hydrogen chloride of high concentration or sulfur dioxide.
In chemical industries such as medicine, agricultural chemicals, dyestuff, corrosive gas such as hydrogen chloride that discharges in the production process or sulfur dioxide need to be absorbed processing.Both industrial chemicals can be reclaimed, environment can be protected again.
For the absorption of high concentration chlorination hydrogen, because its aqueous solution Henry'S coefficient is very little, it is bigger to absorb heat, and the absorption area that absorption process needs is also not very big, but but requires to have good heat transfer efficient.Absorb if carry out thermal insulation with general jar class, tower class, absorption efficiency is low, can not get the concentrated hydrochloric acid of industrial significance.
Prior art is to adopt the membrance-type absorber of graphite material to implement this chemical process.Though the thermal conductivity of graphite and corrosion resistance are all fine, can obtain satisfied assimilation effect.But because its shell is made of iron, and the residing environment of equipment often is again the denseer place of hydrogen chloride acid mist, and the ironware that equipment exposes is very fast by the hcl corrosion of environment acid mist and leakage.The damage of shell causes the damage of graphite member, and the maintenance of graphite member, difficulty is very big, makes the membrance-type absorber of graphite material, have more than is needed how long just scrapping.Because the intensity of graphite is low, proportion is bigger, poor processability is made, transports, installs, used and keeps in repair, and is all inconvenient, so, the membrance-type absorber of graphite material, unsatisfactory.
For the sulfur dioxide of high concentration, similar situation is also arranged.
The purpose of this utility model will provide a kind of membrance-type absorber of New Type Material exactly, and it had both had the high advantage of absorption efficiency of the membrance-type absorber of graphite material, can overcome many deficiencies of the membrance-type absorber of graphite material again.
Task of the present utility model is achieved in that
Make a kind of falling film absorbre that constitutes by shell, absorber portion and last (descending) short circuit, the invention is characterized in:
The absorber portion of this falling film absorbre is made by graphite modified polypropylene material,
The remainder of this falling film absorbre is made by polypropylene material,
In the last short circuit of this falling film absorbre liquid distribution device is arranged.
The absorber portion of this falling film absorbre is graphite modified polyacrylic tubulation.
The ratio of height to diameter of the graphite modified polypropylene tubulation of the absorber portion of this falling film absorbre is: 50～400.
During the work of this falling film absorbre, the gas phase flow velocity greater than/equal 15～25m/s(and when flowing)
Or when work, the gas phase flow velocity greater than/when equaling 7～15m/s(adverse current).
The shell of this falling film absorbre, last (descending) short circuit, tube sheet and pipe connecting flange are polypropylene material and make.
This falling film absorbre is characterized in that the liquid distribution device in the short circuit is a teethed hole type tube.
This falling film absorbre is characterized in that the liquid distribution device in the short circuit is to cut line groove.
This falling film absorbre is characterized in that the liquid distribution device in the short circuit is the conical distribution head.
This falling film absorbre is characterized in that the liquid distribution device in the short circuit is the spiral grooves distribution head.
This falling film absorbre is characterized in that all parts can all be to be made by polypropylene material also.
Because the tubulation of the absorber portion of this falling film absorbre is to draw with graphite modified polypropylene to form, the remainder of this falling film absorbre comprises shell, upward (descending) short circuit, tube sheet, pipe connecting flange etc. are made by polypropylene material; Or all member is made by polypropylene material, and is not only corrosion-resistant, and the intensity height, thermal conductivity and all good to water lubrication.
Because, this falling film absorbre has added a liquid distribution device in last short circuit, it is evenly distributed to each vertical absorption in the tubulation with absorbent, and be form of film toward dirty, absorbed gas from top to bottom when flowing (and) or from bottom to top (during adverse current) by the tubulation space, gas-liquid two-phase carries out mass transfer and absorbs the absorption efficiency height on the liquid film that flows.Pipe is outer to be flowing coolant, to take away the absorption process liberated heat.Like this, both reach the purpose of absorption, satisfied the corrosion resistant requirement of complete equipment again.
Falling film absorbre provided by the invention than existing stone film membrance-type absorber, has the following advantages:
1. complete equipment is all corrosion-resistant;
2. in light weight, same absorption area, the falling film absorbre that the utility model provides, weight only is 1/4～1/5 of graphite membrance-type absorber;
3. the falling film absorbre that provides of the utility model, the mechanical strength of used material and processing characteristics are all much better than graphite, therefore, the design of equipment, manufacturing, transportation, install, use and keep in repair all very convenient;
4. the falling film absorbre that provides of the utility model, it absorbs tubulation is nonpolar, and inside and outside wall is smooth, and it is less scaling to manage outer cooling water, in case tied dirt, also can acid scale removal, can etching apparatus.And the shell of graphite membrance-type absorber is an iron, can not acid scale removal, and long-term the use can be reduced heat transfer efficiency.
Below in conjunction with accompanying drawing the utility model is further elaborated:
Figure one is a structural representation of the present utility model.
Figure two～figure five is shape exemplary graphs of liquid distribution device of the present utility model.
Among the figure one, the 1st, last short circuit, the 2nd, end socket, the 3rd, liquid distribution device, the 4th, shell, the 5th, absorber portion tubulation, the 6th, absorption liquid import, the 7th, absorption liquid feed pipe, the 8th, the absorption liquid outlet, the 9th, be absorbed gas feed (outlet), the 10th, be absorbed gas vent (import), 11 and 12 is cooling water import and exports.
