Description
[technical field]
The present invention relates to a kind of dried dust retracting device, more particularly, the present invention relates to a kind of amino acid whose dried dust retracting devices such as lysine that are used for.
[background technology]
Lysine is one of eight kinds of primary amino acids of needed by human; Lysine and threonine are topmost amino acid in the Animal nutrition; Because other several seed amino acids are equal can the replacement by analog or the compact optical isomers with X-ketone group or hydroxyl generally; But lysine is unique only L-type composition in eight seed amino acids could effectively be utilized; Since lysine can not be in human body by about reduction amination or transamination generate, must be by absorbing in the food, so it is a kind of most important primary amino acid.
Lysine can be regulated the human body metabolic balance, and lysine is that synthetic carnitine provides structural constituent, and carnitine can impel the synthetic of aliphatic acid in the cell.In food, add a spot of lysine, can stimulate the secretion of pepsin and hydrochloric acid in gastric juice, improve the gastric secretion effect, play the effect that improves a poor appetite, promotes physical growth of children and growth.Lysine can also improve the absorption of calcium and accumulation in vivo thereof, quickens bone growth.As lack lysine, and can cause the gastric juice branch to ooze deficiency and apocleisis, alimentary anemia occur, cause that nervous centralis is obstructed, depauperation.
Lysine is at the ancillary drug that pharmaceutically also can be used as diuretics, and treatment reduces the lead poisoning phenomenon that causes because of chloride in the blood, also can generate salt with acidic drug (like salicylic acid etc.) and alleviate bad reaction, share then with methionine and can suppress the severe hypertension disease.
In recent years, feed industry and food industry both at home and abroad is fast-developing, and the purposes that lysine is new on the medical industry is constantly excavated, and lysine has become good development prospect on a kind of international market, and breach is bigger on the domestic and international market.
The generation method of lysine has extraction process, chemical synthesis and enzyme process and fermentation method, generates the large enterprise of lysine in recent years in the world, most direct fermentations that adopt.
At present; Domestic lysine market demand is bigger; Above production method does not reach the demand in market far away; Main cause comprises following three aspects: the one, because people's living standard and raising that food nutrition is needed, and the raising of feed industry product technology level, quality requirement, promote the demand of market greatly to lysine; The 2nd, because the too high process matched therewith of lysine investment of production equipment is huge, limited the construction progress of grassroot project; The 3rd, market agricultural byproducts price rises, and particularly the price of beans becomes extraordinarily kind, has strengthened production cost, causes economic pressures and burden to manufacturing enterprise, has restricted the growth rate that domestic lysine is produced.
In the amino acid whose production technology such as lysine, the recovery of dust is one of important step in the production technology, in the traditional handicraft amino acid such as the lysine after the crystallization is transported to the fluidized bed dryer inner drying with the amino acid such as lysine that other mixtures are sent into after seperator separates, separates at last; In fluid bed, material removes moisture through 1 district, 2 districts, the heating of 3 districts, after cooling off through 4 districts that are connected with cold air again; Separate through sieve, oarse-grained screenings returns sulfuration again after pulverizer is pulverized long, and fluid bed top has air-introduced machine constantly to discharge internal gas; Keep constantly circulating of the interior gas of fluid bed, but when discharging gas, because the air-introduced machine strong suction; A large amount of amino acid such as lysine are also carried secretly by gas and are entered atmosphere in the fluid bed, cause great waste, simultaneously to around environment also produced bad influence; Mostly traditional recovery technology is the cloth bag collection, and the drawback of existence is for when the air pressure in the cloth bag is much, and remaining dust can not get into cloth bag again; Efficient is low; When air pressure reached certain limit, the cloth bag explosive existed potential safety hazard simultaneously.
To sum up, how the amino acid such as lysine of a large amount of losses are recycled, be a difficult problem of puzzlement manufacturing enterprise always.
[summary of the invention]
The technical issues that need to address of the present invention are to overcome the defective of existing production technology, provide a kind of have simple in structure, organic efficiency is high, has also that application is wide, an environmental protection, advantage such as energy-conservation.
For addressing the above problem, the present invention realizes through following technical scheme:
A kind of amino acid whose dried dust retracting devices such as lysine that are used for; Its structure mainly is made up of: parts such as air-introduced machine, rewinding case, water supplement port, discharge outlet, water spray, exhaust outlet, liquid return hole, inlet, recovery tower, circulating pump, and the outer setting of recovery tower has air-introduced machine, water supplement port, discharge outlet, circulating pump; The wall of recovery tower is provided with inlet, exhaust outlet, liquid return hole, discharge outlet; The recovery tower set inside has water spray support, water spray, rewinding case.
Described air-introduced machine, one of which end and fluid bed UNICOM, the inlet UNICOM in the other end and the recovery tower.
Described rewinding case, the bottom that it is arranged at recovery tower is the triangular funnel shape, and the sharp corner of lower end is provided with filter membrane, is used to collect material after treatment.
Described water supplement port, it is through conduit and the inner water spray support UNICOM of recovery tower.
Described water spray support; 4-6 water spray support is row's shape respectively; Be arranged at the inside of recovery tower from top to bottom, and water spray support is provided with 2-5 water and sprays, the 1-3 draining mouth spray on top up; The 1-3 draining mouth spray of bottom down, and bottom 1-3 draining spray support is fixed and conducting through the liquid return hole at recovery tower middle part.
Described inlet, its inlet is inclined upwardly, and is 45.
Workflow of the present invention is: amino acid dust such as the lysine behind fluidized bed drying through air-introduced machine, are got in the recovery tower by inlet; By the water spray on water supplement port input dedicated water to the water spray support, each row's water spray all sprays water, after dust advances recovery tower earlier; Because the difference of dust quality can be elegant to the whole recovery tower, and when running into the water smoke by many rows' water spray ejection; Can make amino acid whose quality increases such as lysine, cause lower floor, until falling into the rewinding case.
The rewinding case is funnel-form, through filtering the water of leaking down, is fed through once more in the water spray in the water spray support through circulating pump by delivery port; Remaining water is discharged through discharge outlet; If the hydraulic pressure in the recovery tower is crossed when hanging down, carry out supplementing water once more by water supplement port, the circular flow successively of above process.
Owing to adopted above technical scheme, compared with prior art, it is following that the present invention has beneficial effect:
1, owing to increased several water sprays in the technology of the present invention, more traditional cloth bag dust collection technology has avoided cloth bag to reclaim the danger of blast.
2, the water among the present invention can be recycled, and can save water and energy consumption about 80%;
3, to reclaim technology simple in the present invention, and it is wide to have application, is equally applicable to other amino acid whose recovery such as tryptophan, phenylalanine, has environmental protection, energy-conservation etc.
