Abstract
The invention relates to a dissolving pot used in a ground turpentine and/or middle-layer turpentine liquid dissolving process. The dissolving pot comprises a dissolving pot body, an upper discharge tube, a dissolving steam pipe, a pressing steam pipe and a drain pipe; the dissolving steam pipe is communicated with the pressing steam pipe on the upper part; the lower end of the dissolving pot body has an inverted cone structure, and the bottom of the dissolving pot body is provided with a bottom slag discharge tube; impurities with a large specific gravity are easy to precipitate and are discharged through the bottom slag discharge tube based on a gravity force; and the materials are not in contact with the impurities when the turpentine is discharged, therefore the losses of soluble oil and the turpentine are reduced. In the invention, because the dissolving pot with a conical bottom is used, the impurities with the large specific gravity are easy to precipitate and discharge; the materials are not in contact with the impurities such as sediment and the like when the turpentine is discharged, therefore the losses of the soluble oil, such as turpentine oil and the like and the turpentine are reduced to a maximal extent, so that the recovery rate of a product is increased, and the glossiness of the product is improved.
Description
Technical field
The present invention relates to a kind of dissolving pan and dissolving method thereof that uses in rosin and/or the middle level fat liquid dissolution process that land.
Background technology
Utilization is landed rosin and middle level fat liquid and is produced rosin two kinds of technologies are arranged at present:
The one, traditional technology: promptly every pot of rosin, turps, water, oxalic acid add in the dissolving pan in proportion, by steam dissolving back gained fat liquid is transported to high-order transition pot, enters the clarifying kettle standing demix then, the fat liquid after the water of draining, feasible the leaving standstill enters the still pot distillation.In this process, because land coarse filtration baffle plate that rosin will be by dissolving pan to high-order pot, impurity and earth can be taken away a large amount of rosin and turps, do not cause fat liquid quality high and cause great waste easily.
The 2nd, add water heating for dissolving, squeeze and filter, purged and packed and obtain the rosin work in-process landing rosin, and then press the traditional technology that rosin produces and produce rosin (Chinese patent ZL200610019078.3).Its drawback is to adopt the pressing device of using in similar bean curd, the bran cake production process need expend great amount of manpower and machinery in the squeeze and filter process; Simultaneously, to wash dirt impurity with a large amount of water, can discharge the stronger sewage of a large amount of acidity, environment is polluted, cause enterprise's pollution treatment to have high input, cause public interest and company interest impaired in pairs in the purged and packed process.
Summary of the invention
The present invention has designed a kind of dissolving pan and dissolving method thereof that uses in rosin and/or the middle level fat liquid dissolution process that land, and the technical problem of its solution is:
(1) loss of the dissolving oil in the dissolving pan is big in the existing rosin production process, and hand labor intensity is big and seriously polluted;
(2) rosin that utilizes traditional dissolving pan to produce can come in contact with solid impurity, causes the rate of recovery problem on the low side of rosin.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of dissolving pan that uses in rosin and/or the middle level fat liquid dissolution process that lands, comprise dissolving pan pot body, top discharge nozzle, dissolved vapor pipe, binder vapour pipe and evacuated tube, described dissolved vapor pipe and described binder vapour pipe are in top UNICOM, described dissolving pan pot body lower end is an inverted cone structure, its bottom also is provided with a bottom residue outlet, heavy impurity sinks to the bottom and relies on gravity to pass through described bottom residue outlet easily and discharges, material will not come in contact with impurity during the rosin discharging, has reduced the loss of dissolving oil and rosin.
Further, also be provided with the residue outlet control valve on the residue outlet of described bottom.
Further, the lower end of described dissolving pan is not provided with the coarse filtration baffle plate, and is provided with the top discharge nozzle in the upper end of described dissolving pan, and the mouth of pipe of described top discharge nozzle is positioned at the oxalic acid solution layer top of dissolving the back standing demix that finishes.
This lands the dissolving pan that uses in rosin and/or the middle level fat liquid dissolution process and dissolving method thereof compared with prior art, has following beneficial effect:
(1) one of beneficial effect of the present invention is to use awl end dissolving pan, heavy impurity sinks to the bottom, material does not contact with impurity such as silts during the rosin discharging, at utmost reduced the loss of turpentine wet goods dissolving oil and rosin, improve product the rate of recovery, improve the glossiness of product, reach and reduce labor strength, reduce discharge of wastewater, increase the purpose of economic benefit.
(2) also increased water-washing step in the dissolving method that the present invention uses, can decolour, made the rosin that enters in the high-order transition pot have better quality of colour to rosin.
(3) the present invention is because by being provided with the top discharge nozzle at oxalic acid solution layer top, make only dispensing liquid rosin of top discharge nozzle, the possibility of further having avoided liquid rosin and solid impurity layer to come in contact, thereby make the rosin quality that obtains in the high-order transition pot improve greatly, the content of rosin also reduces greatly in the impurity of Pai Chuing simultaneously, has improved the rosin turnover ratio greatly.
