Description
Technical field
The present invention relates to chemical equipment technical fields, and in particular to desulphurization plant after vegetable oil burning.
Background technology
By introducing the analysis and research of sulfur removal technology pilot factory situation condition to domestic and international desulfurization technology and domestic electrical industry,
3 classes such as desulfurization after sulfur method can generally be divided into desulfurization in burning preceding desulfurization, burning and burn at present.
Desulfurization, also known as flue gas desulfurization (Flue gas desulfurization, abbreviation FGD) after wherein burning, in FGD skills
In art, is divided by the type of desulfurizing agent, following five kinds of methods can be divided into:With CaCO3Calcium method based on (lime stone), with MgO
Based on magnesium processes, with Na2SO3Based on sodium method, the ammonia process based on NH3, organic alkaline process based on organic base.
The commercial technologies generally used in the world are calcium methods, and proportion is 90% or more.
Desulfurization technology can be divided into again by the dry and wet state of absorbent and desulfurization product in sweetening process wet method, dry method and
Half-dried (semi-moist) method.Wet FGD technology is desulfurization and processing desulfurization production under wet condition with the solution containing absorbent or slurries
Object, the method have many advantages, such as that desulphurization reaction speed is fast, equipment is simple, desulfuration efficiency is high, but generally existing seriously corroded, operation dimension
It protects costly and easily causes secondary pollution problems.
The desulfurization absorption of dry method FGD technologies and product processing carry out under dry state, which arranges with no sewage spent acid
Go out, equipment extent of corrosion it is lighter, flue gas is high without smoke temperature after significant hypothermal, purification in purification process, be conducive to chimney exhaust diffusion,
The advantages that secondary pollution is few, but that there are desulfuration efficiencies is low, and reaction speed is compared with the problems such as slow, equipment is huge.
Semidry method FGD technologies refer to desulfurizing agent in the dry state desulfurization, under wet condition regeneration (as washing activated carbon again
Raw flow), or under wet condition desulfurization, under dry state processing desulfurization product (such as spray drying process) flue gas desulfurization skill
Art.Especially under wet condition desulfurization, handle under dry state the semidry method of desulfurization product, with its existing wet desulphurization reaction speed
The advantage that degree is fast, desulfuration efficiency is high, and have dry method without the easy-to-handle advantage of product after the discharge of sewage spent acid, desulfurization and by people
Extensive concern.By the purposes of desulfurization product, two kinds of the method for abandoning and absorption method can be divided into.
In the prior art, a kind of desulphurization plant was proposed：Including desulphurization plant ontology, and it is arranged on desulphurization plant ontology
Desulfurization cylinder, the desulphurization plant ontology is provided with minor diameter desulfurization pipe, and the minor diameter desulfurization pipe is mounted in desulfurization cylinder
Centre, the S-type structure of minor diameter desulfurization pipe are bent back and forth, and the desulphurization plant ontology is provided with reative cell, the reative cell
Mounted on the lower section of desulfurization cylinder, the desulphurization plant ontology is provided with quantitative desulfurizing agent liberation port, the quantitative desulfurizing agent release
Mouth is mounted on the top both sides of desulfurization cylinder, and the desulphurization plant ontology is provided with filter chamber, and the filter chamber is mounted on desulfurization cylinder
Lower section；Although paint is imported into desulfurization cylinder by the desulphurization plant using loading hopper, because the minor diameter in desulfurization cylinder is de-
The shape that sulphur pipe is bent back and forth because of S-type structure, therefore the time of reflection can be increased so that desulfuration efficiency increases, still,
There are the incomplete problems of desulfurization, are only bent back and forth by the S-type structure of desulfurization pipe, only increase distance, and reaction still exists
In reative cell, in the extremely short time, surface layer is only reacted, unreacted desulfurization is gone back in inside, and filter chamber is seeped into regard under, generally,
Efficiency is low, and desulfurization is incomplete, and there is still a need for carry out desulfurization again for recycling.
