(1) product application
Such chemical trades as the coking , city gas , enterprise's gas desulphurization of angry , medium and small-scale nitrogen of oil field ,etc。
(2) overview of equipment
The dividing type melts the sulphur cauldron and is made up of three parts mainly in NF type: Piece, interior barrel and vapour inside insert set, piece tube is it can is it corrode to produce to make by stainless steel material all inside among them. A advanced one pieces of structural design make sulphur and solution separate completely inside, one step makes sulphur products.
(3) production capacity

The sulphur of certain type specification retrieves its ability of the cauldron and relates to density of sulphur and foam , the higher the density of the sulphur is in the foam, the greater production capacity is. But the density of foam can't be getting large. Through measuring actually, when the density of the sulphur and foam is about 6%, the production capacity of every specification cauldron is as follows:
Type NF600-3 NF800-3 NF900-3
Day sulphur yield About 1. 5T About 2T 2.5T—3T
Annual sulphur yield About 500T About700 About900

(4) consume
Motive force is consumed . Because this craft and traditional sulphur retrieve the craft to compare , has only kept the sulphur cauldron of melting on the equipment, its motive force is consumed and only limited to sulphur and foam and collect from trough to transport energy consumption which melts the sulphur cauldron.
The vapour is consumed . Enter sulphur and foam temperature in the cauldron generally about 40 degrees, the clear liquid temperature discharged is 60-90 degrees, the higher the density of the sulphur is in the foam, the less solution the ones that retrieved certain sulphur and discharged are, the steam consumes the lower. Through determining, when the density is about 5%, one ton of sulphur consumes 0. 1 of saturation steam of 4Mpa. 5 tons.
The chemical supplies consumption is reduced. There are not three wastes that are discharged in this craft , therefore has reduced the loss of the chemical supplies . It is different to look at scale and original sulphur and retrieve methods to adopt , use the continuous sulphur to economize the chemical supplies to hundreds of thousands yuan in ten thousand yuan after retrieving the cauldron
(5)the characteristic
1、 characteristic, handling capacity elasticity heavy, deal with sulphur foam 3000-5000kg/h normally.
2 、Craft simple and equipment less, one finish separation of sulphur and melt the sulphur.
3、Needn't build the method to relatively filter first and then melt the sulphur in the factory building and invest the province .
4、Separate temperature to be low , melt active principle of sulphur can destroy , solution low in sulphur content (suspend sulphur lighter than 0. 8 grams / liter), can recycle , will not stop up the desulphurization tower , economize the industrial chemicals.
5、Operate simple , operate worker need special training , pump less machine , alone class first.
6、The vapour is consumed 1 low, one ton of sulphur consumes vapour. About 7 (differ according to catalyst , include more than 6% sulphur by sulphur foam).
7、There is no three wastes discharge , accord with the national requirement for environment protection.

(7) sulphur quality
Using the continuous sulphur to retrieve the cauldron and is in flowing in order in the cauldron because of the supplies, the solution was not turned into the course , there is no salt dreg to turn into. So, will not produce it like second sulphur while using the traditional sulphur to retrieve the way . Sulphur quality accords with GB2449-81 demand . The factor influencing sulphur quality is equally such impurity as dust , carbon China ink , tar ,etc.. Though proportion of liquid sulphur heavy than general impurity, sulphur and impurity can not keep the absolute stability with interface , cauldron of wall in cauldron, always some impurity is arranged with the melting sulphur Proposing using the factory to pay attention to the dust removal of coal gas , , except that the tar works, such impurity as the suggestion dust , tar ,etc. more factories at the same time, reduce and put the number of times of sulphur in the sulphur is retrieved and operates , make the melting sulphur in the cauldron keep higher interface, arrange the dust regularly, can get up to certain result . But the one that should reduce impurity in most basic measure is brought into.
