Description

A kind of gas scrubbing tower

Technical field

This utility model belongs to gas-liquid two-phase separation, environmental protection, Process Equipment field, particularly to a kind of gas scrubbing tower.

Background technology

Flue gas ash removal, sweetening process generally use alkali liquid washing method, spray (even atomization) alkali liquor and be allowed to and flue gas in scrubbing tower Being sufficiently mixed contact, to dust washing absorption, to SO2 reaction removing, after process, flue gas is discharged from scrubbing tower top.The most general Following problem is seriously caused: 1, increase alkali liquor, water content consumption all over there is problems of cigarette gas carrying liquid (fine drop or title mist)；2、 Rear portion equipment (reheater, air-introduced machine etc.) burn into is caused to block；3, smoke moisture increases affects diffusion and increases the weight of haze, takes out of Tiny alkali liquor drip dehydration formed white cinder pollution air, increase the weight of haze.Therefore at present in the urgent need to a kind of band gas purification merit The scrubbing tower of energy, meets current environment protection, the needs of improvement haze.

Summary of the invention

The purpose of this utility model is to provide a kind of gas scrubbing tower, reinforcement gas-to-liquid contact improves functional while, after strengthening Portion's gas takes off liquid, except mist treatment measures, meet gas purification requirement.

This utility model solves its technical problem and be the technical scheme is that and include that gas feed, gas outlet, cleaning mixture enter Mouth, leakage fluid dram, is characterized in that: two-part before and after scrubbing tower employing, leading portion is the turbulence type washing section reducing diameter, and inside sets Set high density spray head or distributor, baffle plate are set；Back segment is the settling section of enlarged diameter, and inside arranges silk screen, inertia divides From device, whizzer；Back segment is 1.5～4 with the sectional area ratio of leading portion.

Further, washing section is monotubular structure, or is arranged on the many barrel structures in 1 shell；Washing section Internal baffle is circle cone Baffle plate or herringbone baffle plate or grid.

Further, whizzer is cyclone separator or spiral-flow plate-type separator, is several parallel connections or 1 monoblock type, It is arranged in settling section interiorly or exteriorly.

This utility model innovative point and good effect:

This utility model innovative point is: two-part before and after scrubbing tower employing, and leading portion is the turbulence type washing section reducing diameter, internal High density spray head is set or distributor, baffle plate are set；Back segment is the settling section of enlarged diameter, and inside arranges silk screen, inertia Separator, whizzer；Back segment is 1.5～4 with the sectional area ratio of leading portion.

This utility model good effect is: 1, using the turbulence type washing section reducing diameter, gas contacts evenly with liquid, more Fully, be conducive to improving clean result.2, using the settling section of enlarged diameter, inside arranges silk screen, inertia separator, is centrifuged Separator, except mist, (1 grade is to reduce gas flow rate major diameter drop natural subsidence to three grades of de-liquid, and 2/3 grade is to arrange silk screen and be centrifuged During separator intercepts/drop of minor diameter, finally realize gas purification.

Detailed description of the invention

Seeing that Fig. 1, washing section 3 use monotubular structure, inside arranges distributor pipe 8A, distributor 9, baffle plate 10, bottom and gas Entrance 4 connects, and upper end is connected with settling section 2.Settling section 2 uses enlarged diameter structure, and inside arranges silk screen 6, is centrifuged and divides From device 7, lower end is connected with washing section 3, and upper end is connected with gas outlet tube 1.Settling section 2 and the sectional area ratio of washing section 3 It is 1.5～4.

Seeing Fig. 2, equipment is that gas outlet tube 1, upper body 2A (inside is settling section), central enclosure 2B are (interior the most successively Portion is washing section), lower case 2C (inside is air inlet section 13).Many washing section 3A bottoms are by support plate 11 and lower case Body 2C connects and connects with air inlet section 13, and inside arranges number row's high density spray head 8, and upper end is uncovered and reaches upper body 2A In.Arranging silk screen 6, monoblock type separator 7A inside upper body 2A, upper end is connected with gas outlet tube 1.Lower case 2C (inside is air inlet section 13) is connected with gas access 4, and bottom is provided with leakage fluid dram 5.

Seeing that Fig. 3, washing section 3 use monotubular structure, inside arranges number row's high density spray head 8, and upper end is connected with gas access 4, Lower end is connected with inertia separator 7B and reaches settling section 2 inside.Settling section 2 uses enlarged diameter structure, and inside is provided with silk screen 6, bottom silk screen 14, upper side is connected with gas outlet tube 1, and bottom is connected with hydrops bag 15.

Seeing Fig. 1, impure (drop, solid particle etc.) gas enters from gas access 4, high flow velocities in washing section 3 Flow up, cleaning mixture from distributor pipe 8A enter, enter 10 sections of baffle plate through distributor 9, gas and cleaning mixture be fully contacted into The alternate transmission of row, the impurity (drop, solid particle etc.) in gas is transferred in cleaning mixture, and it is heavy that gas is purified above entrance Fall section 2, cleaning mixture then flow to bottom and discharges from leakage fluid dram 5.Silk screen 6 region is first passed around after settling section 2 above gas entrance Removing major diameter drop, enters back into high speed rotating flowing in whizzer 7, and under centrifugal action, drop is thrown toward inwall and leads to Cross discharging tube to discharge, purify gas and discharge from gas outlet tube 1.

Seeing Fig. 2, impure (drop, solid particle etc.) gas enters air inlet section 13 from gas access 4, enters from end opening Many washing section 3A high flow velocities flow up, and cleaning mixture sprays along cross section through spray head 8, and gas is fully contacted with cleaning mixture Carrying out alternate transmission, the impurity (drop, solid particle etc.) in gas is transferred in cleaning mixture, and gas is purified entrance top In housing 2A, cleaning mixture then flow to bottom and discharges from leakage fluid dram 5.Gas first passes around silk screen 6 district after entering upper body 2A Territory removing major diameter drop, enters back into high speed rotating flowing in monoblock type separator 7A, in drop is thrown toward under centrifugal action Wall is discharged by discharging tube, purifies gas and discharges from gas outlet tube 1.

Seeing Fig. 3, impure (drop, solid particle etc.) gas enters from gas access 4, flows downward in washing section 3, Cleaning mixture sprays along cross section through spray head 8, and gas and cleaning mixture are fully contacted and carry out alternate transmission, impurity in gas (drop, Solid particle etc.) it is transferred in cleaning mixture, gas is purified and flows out through inertia separator 7B, and major diameter drop drains into bottom, Gas is flipped up entering settling section 2, from gas outlet tube 1 after silk screen 6 region removes drop further in settling section 2 Discharge.Cleaning mixture then flow to bottom and discharges from leakage fluid dram 5 through hydrops bag 15.
