Description

Caustic wash tower

Technical field

The utility model relates to chemical gases processing technology fields, particularly relate to a kind of sufficient caustic wash tower of gas-liquid contact.

Background technique

Chemical combination synthetic gas is the generation for being usually associated with other gases, needed for the presence of these gases leverages The quality of gas, it is necessary to remove, but during removal, it is contemplated that the factor of environment and the energy, while gas purification, The gas of impurity will not be generated again, currently, removing the sour gas in biology using the method for alkali cleaning in industrial process units Body mainly has chlorine, hydrogen chloride, carbon dioxide.The equipment belongs to that differential contacts are reverse-flow, and the intracorporal filler of tower is gas-liquid two-phase The basic building block of contact, it can provide sufficiently large surface area, contact ascending air and decline lye constantly in packing area, The concentration of liquid is more and more low in ascending air, reaches emission request.

Utility model content

The utility model proposes a kind of caustic wash tower, solve the problems, such as that gas-liquid two-phase contacting efficiency is low in the prior art.

The technical solution of the utility model is achieved in that a kind of caustic wash tower, including tower body, tank, the tower body are divided into Upper section, lower section two parts, the tower body upper section top are provided with gas outlet, and there are two up and down for setting on the tower body lower section side wall Hand hole arranged side by side, the internal cavities between described two hand holes are set as packing area, being provided with and having held below the packing area The baffle of support effect is provided with air inlet on another side wall of tower body lower section and is located at the lower section of the baffle, fills out described Expect that the top of area and the hand hole is equipped with bracket, multiple spray heads for spraying lye downward are fixed on the bracket；

The tank includes tank body, cover, circulating pump, and the lye for neutralizing gas, the tank body top are filled in the tank body It is provided with the cover connecting with tower body, circulating pump is provided at the tank base, the circulating pump passes through with the spray head Pipeline connection.

As a preferred embodiment, being provided with two groups of interface of the level gauge on the tank wall, and two groups of liquid levels Meter interface is set side by side up and down, and the thermometer boss of measurement alkali liquid temperature variation is provided on another side wall of tank body, described Cover bottom middle position is provided with water supplement port.

As a preferred embodiment, the tank and the tower body are separate structure, the two passes through flanged joint, The upper section and lower section of the tower body pass through flanged joint.

As a preferred embodiment, the center of the baffle is provided with through-hole, the tower body and the tank connect It is provided with inner sleeve on the flange at the place of connecing, the upper end of the inner sleeve is through the through-hole on the baffle, the baffle and the method A seal chamber is formd between orchid, the air inlet extends through tower body side wall, Xiang Suoshu inner sleeve and connect perforation, in institute It states and is provided with aeration aperture and exhaust valve in the lower sidewalls of hand hole, the exhaust valve and aeration aperture are up and down and column distribution.

As a preferred embodiment, being provided with circular groove on the through-hole wall, the groove has been embedded with close The sealing ring of envelope effect.

As a preferred embodiment, being provided with a circle retaining ring at the top edge of the inner sleeve.

As a preferred embodiment, being provided with the valve for adjusting lye conveying capacity size on the pipeline.

As a kind of preferential embodiment, one layer of liner PO is provided on the inner wall of the tower body and the tank.

As a preferred embodiment, the thermometer boss is connect with the tank wall at 30 ° of angle-inserting types.

After above-mentioned technical proposal, the beneficial effects of the utility model are: the circulating pump of tank base is defeated lye It is sent on spray head and sprays downwards, gas enters in tower body, and rising inversely contacts with lye in packing area and neutralize instead It answers, the utility model increases the area of packing area, comes into full contact with lye more with gas, and liquid is dense in ascending air Degree is more and more low, reaches discharge standard.Hand hole arranged side by side up and down there are two being arranged on tower body lower section side wall, for replacing filler Material in area, material addition number can be judged according to the acid intensity contained in gas, first pass through top hand hole handle Material adds in packing area, and the material in packing area is taken out by the hand hole of lower section in side when such as needing replacing material, then again Material is added, simple and convenient, be easily changed, material is lived with baffle support, to prevent the material in packing area from falling to In the intracorporal lye of tank, the water inlet of circulating pump is blocked, makes circulating pump cisco unity malfunction, can be burnt out on circulating pump when serious Motor causes economic loss and delays production.

Two interface of the level gauge on tank wall are used to observe lye in the intracorporal liquid level of tank, allow one mesh of staff So, lye benefit can be carried out by the water supplement port on cover when the intracorporal liquid level of tank is reduced to lower section interface of the level gauge when lye It gives, to prevent lye quantitative change few, water shortage on circulating pump and the neutralization reaction for influencing lye and gas cause gas not reach Mark discharge, pollutes environment.

Parting flange formula connects between tower body and tank, facilitates the maintenance of staff, when certain part therein is damaged Bad when, can be allowed to separate, allow huge entirety to become small portion, keep crane more easily complete by the flange of centre connection It is more time saving and energy saving at unloading task.

Due to foring a seal chamber between baffle and flange, the past sealing interacvity air-filling of aeration aperture, seal chamber can be passed through Interior gas slowly can push baffle to rise when increasing to certain pressure, and material is driven to rise, to facilitate material from hand It takes in hole, turns the exhaust valve on side wall, discharge the gas in accommodating chamber, as gas is gradually reduced, baffle be will be slow Decline, Lai Shixian baffle covers inside to be vertically moved up or down.It can thus be filled out according to the acid intensity contained in gas to adjust The size for expecting area, is effectively controlled the addition of material, and the waste of resource is reduced under the case where reaching discharge standard. It is flowed into tank body for the lye after gas neutralization reaction by inner sleeve and flange, is used with the intracorporal lye mixing circulation of tank.

On through-hole wall be embedded with sealing ring, sealing ring can anti-baffle plate gas in lifting process leakage, if gas Leakage will cause the lifting effect that the pressure transient in seal chamber influences baffle.

Due to being provided with a circle retaining ring at the top edge of inner sleeve, in the case where that interior can not regard on gas push baffle It rises, baffle, which is blocked after rising at the top of inner sleeve by retaining ring, to be carried out anti-baffle plate and rise excessive to be detached from from interior set.

It, can be according to needed for production in order to reduce the valve for being wasted in pipeline and being equipped with adjusting lye conveying capacity size of resource To adjust the size of spray head sprinkling lye.

Due to one layer of PO of liner equal on the inner wall of tower body and tank, the chemical component in lye and gas is alleviated to tower The erosion of body and top tank structure improves its service life.

Thermometer boss oblique cutting enters to increase in tank body lye the contact area of lye and thermometer, keeps readings more quasi- Really, compare and be suitble to take inclination mounting means.
