Abstract
The invention discloses an environment-friendly unhairing method and an ash lye reclaiming device. The environment-friendly unhairing method comprises the steps of ash coating, stacking, unhairing and ash immersion, wherein the ash coating step comprises the following substeps: (1) applying the ash lye; (2) reclaiming the ash lye; and (3) treating the ash lye. The ash lye reclaiming method for implementing the environment-friendly unhairing method comprises an ash coating plate, wherein the ash coating plate is latticed and arranged on the top of a box type ash coating operating platform of which one side is provided with at least one outlet; a corresponding reclaiming tank is arranged under the outlet; and an inclination angle is formed in the direction from a bottom plate of the box type ash coating operating platform to the outlet. The invention not only reduces the environmental pollution of sulfide but also saves raw materials and reduces the cost.
Description
Technical field
The present invention relates to method and device, particularly a kind of environment-friendly type depilating method and the grey alkali lye retrieving arrangement of depilation operation in a kind of leather-making technology.
Background technology
At present, along with developing rapidly of curriery, the discharging of tanning sewage has become the discharging of the hazardous and noxious substances of more and more serious pollution problem, particularly sulfide etc.In the bag ash process in leather-making technology; Usually use the formulated grey alkali lye depilation of Sodium Sulphide; Promptly introduced a large amount of sulfonium ions, and general depilation device adopts all is flat bag hawks, the left redundant sulfide ions and the sulfide of formation just can only be gone out with discharge of wastewater after spreading upon grey alkali lye on the skin base with bag ash brush; Not only serious environment pollution, and waste starting material.
Summary of the invention
Technical problem to be solved by this invention provides a kind of environment-friendly type depilating method and grey alkali lye retrieving arrangement, has not only reduced environmental pollution of sulfide, and has practiced thrift starting material, has reduced cost.
The present invention's technical scheme that adopts of dealing with problems is:
A kind of environment-friendly type depilating method comprises ash, banks up, depilation, liming step, wherein wraps grey step and comprises as follows step by step:
(1) is coated with the alkali lye of plastering: the skin base is tiled on the latticed bag hawk, grey alkali lye is spread upon on the skin base uniformly with bag ash brush.
(2) grey alkali lye reclaims: the grey alkali lye that spills from latticed bag hawk when collecting the bag ash gets into returnable.
(3) grey alkali lye is handled: the grey alkali lye to getting into returnable is measured, and regulates its concentration, is circulated to then to be coated with the alkali lye utilization more step by step of plastering.
A kind of grey alkali lye retrieving arrangement of implementing the described environment-friendly type depilating method of claim 1; Comprise the bag hawk; Said bag hawk is latticed, is arranged at the top of box bag ash manipulation platform, and a side of said box bag ash manipulation platform is provided with at least one outlet; The below of said outlet is provided with corresponding accumulator tank, and the base plate of said box bag ash manipulation platform has an angle of inclination to said Way out.
As further improvement, described grey alkali lye retrieving arrangement also comprises pond for recovering, and said accumulator tank is connected with pond for recovering through pipeline; The bottom of said pond for recovering is provided with pump and whisking appliance.
As further improvement, described grey alkali lye retrieving arrangement also is provided with the reuse mixer, and the grey alkali lye in the pond for recovering is promoted to the reuse mixer, regulates reuse after the concentration.
In the present invention, because different skin bases will use the grey alkali lye of different concns to smear, be two kinds therefore with grey alkali liquor preparing, be respectively high density ash alkali lye and lower concentration ash alkali lye; And pond for recovering of the present invention also not only can only connect a box bag ash manipulation platform, and it can connect a plurality of box bag ash manipulation platforms simultaneously, and the unnecessary grey alkali lye that a plurality of box bag ash manipulation platforms are produced reclaims, and utilizes after focusing on again.
The invention has the beneficial effects as follows: latticed bag hawk can make the unnecessary grey alkaline stream in bag ash back go in the grey worktable of box bag, and the box bag ash manipulation platform base plate of inclination can make grey alkali lye from outlet, flow out smoothly, inserts behind the accumulator tank to concentrate through pipeline to be recycled to pond for recovering; The whisking appliance of pond for recovering bottom makes grey alkali lye remain mobile, homogeneous state; Do not produce deposition, pump can be promoted to the reuse mixer with the grey alkali lye in the pond for recovering, regulates recycle after the concentration then; Reduced the discharging of sulfide; Promptly reduced pollution, and practiced thrift starting material, reduced cost environment.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
Below in conjunction with accompanying drawing the present invention is further specified:
Embodiment
Embodiment 1: shown in accompanying drawing; A kind of grey alkali lye retrieving arrangement comprises box bag ash manipulation platform 1, latticed bag hawk 2, is provided with outlet 3 of high density ash alkali lye and lower concentration ash alkali lye outlet 4 on the right side of box bag ash manipulation platform 1; The base plate 5 of case and bag ash formula operator's console 1 has an angle of inclination to two outlet 3,4 directions; Promptly be set to the inclined-plane,, under outlet 3,4, be respectively equipped with corresponding high density ash alkali lye accumulator tank 6 and lower concentration ash alkali lye accumulator tank 7 so that grey alkali lye can flow out from exporting 3,4 smoothly; Two accumulator tanks 6,7 are connected with lower concentration ash alkali lye pond for recovering 10 with high density ash alkali lye pond for recovering 9 through pipeline 8 respectively; Bottom at two pond for recoverings 9,10 also is provided with lift pump and whisking appliance, and whisking appliance makes grey alkali lye remain mobile, homogeneous state, does not produce deposition.Two pond for recoverings 9,10 also are connected with high density ash alkali lye reuse mixer 11 and lower concentration ash alkali lye reuse mixer 12 through pipeline respectively.
Embodiment 2: use high density ash alkali lye bag ash, shown in accompanying drawing, the skin base is tiled on the latticed bag hawk 2; With bag ash brush high density ash alkali lye is spread upon on the skin base uniformly; Smear back unnecessary high density ash alkali lye just along latticed bag hawk 2 toward dirty, open high density ash alkali lye outlet 3 this moment, lower concentration ash alkali lye is exported 4 closes; High density ash alkali lye promptly flows out from high density ash alkali lye outlet 3 along the base plate 5 that tilts; Insert high density ash alkali lye accumulator tank 6, in pipeline 8 flows into high density ash alkali lye pond for recovering 9, with lift pump the ash of the high density in the pond for recovering 9 alkali lye is promoted in the high density ash alkali lye reuse mixer 11 again and carries out concentration determination then; Corresponding Sodium Sulphide of proportioning and lime are used for wrapping grey step with the high density ash alkali lye for preparing at last once more.
