Description
Technical field
The present invention relates to the light alkali reclaiming system of mercerizing range.
Background technology
Printworks mercerizing process needs to process fabric with a large amount of sodium hydroxide solutions, and the concentration of sodium hydroxide solution that each factory uses is not quite similar but roughly all at 18 ~ 25Be
.(Be
。concentration unit for sodium hydroxide solution) in scope, the spent lye after being finished is owing to have passed through the dilution of clear water, and concentration has been reduced to 3 ~ 5Be
., because sodium hydroxide solution consumption is quite large, if directly discharge causes the sharply increase of cost on the one hand, cause very large difficulty on the other hand follow-up sewage disposal, need to consume Waste Sulfuric Acid in addition and go neutralization.Therefore, the larger printing and dyeing enterprise of current scale has oneself light alkali collection a set of to utilize system, but this cover system cost costly, and it is long that the cycle regained by input cost.
The light alkali reclaiming system (as shown in Figure 2) of the mercerizing range that current dyeing & printing enterprise generally adopts, (concentration is at 5Be for the light alkali of recovery.The sodium hydroxide solution of left and right) enter in evaporimeter by preheater, light alkali makes the moisture in light alkali evaporate by the heating of steam in evaporimeter, thus reaches the object of concentrated light alkali, (Nong Du≤25Be after light alkali concentration.After, this concentration can oneself setting, because the most high-alkalinity used in technique is 25Be., therefore concentration is set in 25Be., but add and use alkali concn man-hour lower than 25Be.Alkali words need follow-up still need thin up after be used further to produce, extra consumption part water resource) come back to board and reuse, the words not reaching this concentration are again back to evaporimeter by return duct and continue evaporation and concentration, a large amount of steam of this process need consumption, evaporate a large amount of moisture, consuming time longer and the cost of equipment set is very expensive.
Summary of the invention
The object of the invention is to: provide a kind of light alkali reuse cycle short for overcoming the above problems, the low and light alkali reclaiming system of removal process cost is low mercerizing range of recovery system equipment cost.
The technical solution adopted in the present invention is such:
The light alkali reclaiming system of mercerizing range, comprise light alkali groove, light alkali keep in container, be arranged at light alkali keep in agitator on container, connect described light alkali keep in container hydrogen peroxide feed system, pneumatic operated valve, the first filter, the second filter, concentrated base groove, automatically join alkali groove, automatically join alkali groove switch board, join rear alkali lye and deposit tank, described light alkali groove, light alkali keeps in container, the first filter, automatically join alkali groove is connected by pipeline successively; Described concentrated base groove, the second filter, automatically join alkali groove and connected by pipeline successively; Described light alkali groove and described light alkali are kept between container, described light alkali is kept between container and described first filter, between described concentrated base groove and described second filter and is provided with the first pneumatic operated valve, the second pneumatic operated valve and the 3rd pneumatic operated valve; Described automatic alkali-prepared tank switch board is used for arranging described concentration of lye; Described automatic alkali-prepared tank is joined rear alkali lye and is deposited tank with described and be connected; Describedly join rear alkali lye and deposit the supply of tank for alkali lye needed for mercerizing range.
Further, described light alkali is kept in container and is installed tank level control system, keeping in alkali lye liquid level in container, and liquid level signal is sent to the first pneumatic operated valve, controlling its switch and closing for detecting described light alkali.
Further, described hydrogen peroxide feed system passing ratio pump at regular time and quantity given described light alkali keep in container hydrogen peroxide.
Further, described automatically joining in alkali groove is provided with concentration detection system, automatically joining alkali alkali in groove liquid concentration level, and concentration signal being sent to described second pneumatic operated valve and the 3rd pneumatic operated valve, controlling its switch and closing for detecting.
Further, described alkali alkali in groove liquid of automatically joining deposits tank by joining rear alkali lye described in pump suction.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:
1, the cost of the light chemical recovery system of the present invention is far below prior art;
2, at substantial water, electricity, vapour is needed in existing light chemical recovery system running, average consumption steam per hour 2 tons, cooling water 10 tons.The technology of the present invention compared with prior art water, electricity, vapour cost is almost negligible;
3, prior art recovery alkali lye is consuming time longer, and it is consuming time then shorter that this technology reclaims alkali lye.
Accompanying drawing explanation
Fig. 1 is system construction drawing of the present invention;
Fig. 2 is prior art systems structure chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, the light alkali reclaiming system of mercerizing range, comprise light alkali groove, light alkali keep in container, be arranged at light alkali keep in agitator on container, connect described light alkali keep in container hydrogen peroxide feed system, pneumatic operated valve, the first filter, the second filter, concentrated base groove, automatically join alkali groove, automatically join alkali groove switch board, join rear alkali lye and deposit tank, described light alkali groove, light alkali keeps in container, the first filter, automatically join alkali groove is connected by pipeline successively; Described concentrated base groove, the second filter, automatically join alkali groove and connected by pipeline successively; Described light alkali groove and described light alkali are kept between container, described light alkali is kept between container and described first filter, between described concentrated base groove and described second filter and is provided with the first pneumatic operated valve, the second pneumatic operated valve and the 3rd pneumatic operated valve; Described automatic alkali-prepared tank switch board is used for arranging described concentration of lye; Described automatic alkali-prepared tank is joined rear alkali lye and is deposited tank with described and be connected; Describedly join rear alkali lye and deposit the supply of tank for alkali lye needed for mercerizing range.
