Description

Natural VE production line waste gas recovery processing system

Technical Field

The utility model relates to a natural VE production line waste gas recovery processing system belongs to exhaust-gas treatment technical field.

Background

Vitamin E is called VE for short, and is produced by processing through some steps and procedures in a chemical workshop, a large amount of waste gas with very complex components is generated in the processing process, wherein the waste gas mainly comprises industrial dust, fatty acid methyl ester, alcohols, alkane, olefin compounds, VOCs and the like, and the direct discharge definitely causes great pollution to the air environment and does not reach the discharge standard. The existing waste gas treatment equipment is not only a spray tower, but also a treatment effect is limited by treating various pollution components in waste gas at one time.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve exist among the prior art not enough, provide one kind and can carry out classification's natural VE production line waste gas recovery processing system to multiple pollutant in the waste gas, the treatment effect is better.

The utility model discloses a realize through following technical scheme:

the utility model provides a natural VE production line waste gas recovery processing system, including the spray pipe that end to end links in proper order, wash tank and spray column, the water pipe acts as by having a double-deck water pipe, the left end of double-deck water pipe is connected with an draught fan, the right-hand member of double-deck water pipe links to each other with the wash tank, double-deck water pipe left side lower extreme is connected with an inlet tube, the right lower extreme of double-deck water pipe is connected with an outlet pipe, inlet tube and outlet pipe all are linked together with double-deck water pipe intermediate layer space, a plurality of water jet have been seted up to double-deck water pipe inner wall, the wash tank has connected gradually distillation column and aqueous ammonia jar outward, be provided with the drying cabinet on the blast column top, the inside shower column that is equipped with, the shower passes through the pipeline and links to each other with the alkali lye holding vessel that sets up outside the shower column.

The utility model discloses divide into dust, particulate matter, water-soluble and sulphide and nitride with various pollutants in the waste gas, carry out corresponding processing respectively, the treatment effect is better like this, and the last combustion gas is more environmental protection.

Further preferably, a partition board is vertically arranged in the middle of the washing box, and an arc-shaped board is arranged at the bottom end of the partition board.

Compared with the prior art, the utility model discloses the beneficial effect who has is:

FIG. 2 is a schematic diagram of a transverse cross-sectional structure of a double-layer water pipe;

fig. 3 is a schematic vertical sectional structure of a double-layered water pipe.

In the figure: 1. a water spray pipe; 2. an induced draft fan; 3. a water inlet pipe; 4. a water outlet pipe; 5. a washing tank; 6. a partition plate; 7. an arc-shaped plate; 8. an ammonia tank; 9. a distillation column; 10. a spray tower; 11. a shower pipe; 12. a drying oven; 13. an alkali liquor storage tank; 14. a double-layer water pipe; 15. and a water spraying opening.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

The natural VE production line production waste gas recovery processing system shown in figures 1 to 3 comprises spray pipes 1 which are connected end to end in sequence, washing tank 5 and spray column 10, water pipe 1 acts as by having a double-deck water pipe 14, double-deck water pipe 14's left end is connected with an draught fan 2, double-deck water pipe 14's right-hand member links to each other with washing tank 5, double-deck water pipe 14 left side lower extreme is connected with an inlet tube 3, double-deck water pipe 14's right lower extreme is connected with an outlet pipe 4, inlet tube 3 and outlet pipe 4 all are linked together with double-deck water pipe 14 intermediate layer space, a plurality of water jet 15 have been seted up to double-deck water pipe 14 inlayer wall, washing tank 5 has connected gradually distillation column 9 and aqueous ammonia jar 8 outward, be provided with drying cabinet 12 on the blast pipe of spray column 10 top, spray column 10 is inside to be equipped with shower 11, shower 11 links to each other through pipeline and the alkali lye holding vessel 13 that sets up outside spray column 10.

A clapboard 6 is vertically arranged at the middle position in the washing box 5, and an arc-shaped plate 7 is arranged at the bottom end of the clapboard 6.

The working process is as follows:

waste gas is introduced into and is entered into in the spray pipe by the draught fan, the water inlet pipe leads to water simultaneously, water has the water jet blowout, the dust in the water with waste gas and some pollutants of dissolving in water precipitate, all discharge through the outlet pipe at last, waste gas enters into the wash tank afterwards, the splendid attire is the ammonia in the wash tank, aqueous ammonia in the aqueous ammonia jar becomes the ammonia through the distillation column distillation and enters into the wash tank, waste gas and ammonia in the wash tank and specific catalyst in addition, react, get rid of the sulphide, then waste gas enters into the spray column, shower blowout alkaline liquid in the spray column, contact with waste gas, can detach the nitride in the waste gas, waste gas after final processing is gone through the dry discharge of dry box.

In the description of the present invention, the terms "inside", "outside", "up", "down", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for convenience of description of the present invention and does not require the present invention to be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
