The keys are that the carbonization tower comprises a tower body and a gas inlet pipe, wherein the bottom portion of the tower body is provided with separators which separates the inner portion of the tower body into a plurality of independent regions according to the vertical direction, the height of the separators is not higher than one twice of the height of the tower body, and at least a gas inlet pipe is arranged in each independent region. The inner portion of the tower body is separated into a plurality of regions and is uniformly provided with gas inlet channels, thereby leading the density of the carbon dioxide gas flow to be uniform, having uniform and rapid gas-liquid mixing and carbonation reaction, being capable of properly increasing the gas flow amount to increase yield,,being capable of reducing the loss of the carbon dioxide gas, and reducing the cost.
Description
Technical field
The utility model relates to a kind of carbonators of producing precipitated calcium carbonate, specifically relates to a kind of carbonators that utilizes carbonizatin method to produce precipitated calcium carbonate.
Background technology
The carbonators that existing winnofil production industry generally uses, be an air inlet to be set at tower bottom, high-pressure carbon dioxide gas is from this air inlet input, diffusion is up naturally in calcium hydroxide liquid for the pressure carbon dioxide, contact and chemically reactive with the mixing of calcium hydroxide liquid, produce the winnofil crystal.This carbonators owing to structural reason, exists weak point: the carbon dioxide skewness, fail to realize that gas contacts with the even mixing of liquid, and the utilization rate of carbon dioxide is lower; The deadline of carbonation process is longer relatively; The controllability of the shape and size of the winnofil crystal that produces is relatively poor.Improved plan such as Chinese patent ZL200620027639.X, name is called in a kind of sieve-board type carbonators and proposes: a kind of sieve-board type carbonators, comprise tower body, be arranged on the column plate in the tower body, described column plate is a sieve plate.The air inlet of this carbonators is a house steward, carbon dioxide is exported by house steward, pore through sieve plate flows in the aqua calcis, but because high pressure draught has directionality, inevitably can produce current density height facing to mouth of pipe positive direction, the current density at other position is then lower, particularly because calcium hydroxide liquid has been filled in the space between air inlet pipe and sieve plate, liquid is very big to the air resistance of horizontal proliferation, make gas not spread towards periphery, therefore cause gas inhomogeneous with mixing of liquid, product quality lowers, and the utilization rate of carbon dioxide is reduced, the deadline of carbonation process is longer relatively, also because be subjected to the restriction of local high gas flow density, maximum air demand also is restricted, and has influenced the raising of output.Another important defective of sieve plate scheme is that sieve plate very easily is subjected to the obstruction of winnofil crystal and equipment can't be moved.
Summary of the invention
The utility model technical issues that need to address are, provide a kind of and can make gas and liquid even contact, carbon dioxide can be fully utilized, reaction speed is accelerated, product quality is improved carbonators.
The purpose of this utility model is achieved by following technical proposals: the mixed uniformly carbonators of a kind of gas-liquid, comprise tower body and air inlet pipe, the utility model is provided with the separator that tower body inside is divided into some isolated areas by vertical direction at the inner bottom part of tower body, the height of described separator is lower than 1/2nd of tower body height, is provided with an air inlet pipe in each isolated area at least.
Described separator can be that several tubes with the rounded structure of the concentric setting of tower body enclose.
As preferably, the quantity of described tube circle is two, and the spacing distance between each circle equates.
The admission line quantity that is equipped with between described each circle from coil to coil from inside to outside increases, and can make the pipeline distributed quantity on each regional sectional area on average reach uniform degree by area.
Described separator also can be arranged on the closed lasso of several uniform columns disconnected from each other of tower body inner bottom part, and the cross section of the closed lasso of described column can be circular or fan-shaped or other irregular geometric form.
Described separator can also be the dividing plate that the tower body inner chamber is separated into some isolated areas.
As preferably, the isolated area that some dividing plates of described usefulness are separated is divided into impartial six sector regions with the tower body inner chamber by M shape for adopting six dividing plates.
The height of described separator is 1/5th to 1/2nd of a tower body height.
As preferably, the height of each separator is 1/3rd of a tower body height.
All be provided with flow control valve in the pipeline of described each air inlet pipe, because the difference of the latus rectum of the deviation of pipeline position, pipeline and length, utilize the flow of each admission line of Flow-rate adjustment valve regulation, can reach the whole balanced effect of current density.
As preferably, the outlet end of described each air inlet pipeline is provided with several side direction ventholes along the tube wall periphery, can be with the periphery diffusion of carbon dioxide to air inlet pipe.
As preferably, be provided with in a calcining tube lower end and calcine one section ash discharge pipeline that a lower port is connected mutually.
The beneficial effects of the utility model are: because tower body inside is divided into several regions and admission line evenly is set, make that the carbon dioxide gas current density is even, gas-liquid mixed and carburizing reagent are even and rapid, crystalline size is controlled, also can suitably add the air flow total amount improving output, and can reduce the loss of carbon dioxide and reduce cost.
