Abstract
The invention discloses a press filtering washing water recycling and utilizing system for producing white carbon black, and the system comprises a press filter, wherein the press filter is connected with a water inlet pipe and a filtering solution output pipe; the water inlet pipe and the filtering solution output pipe are provided with control valves; the press filtering washing water recycling and utilizing system further comprises a recycling water storage tank; the recycling water storage tank is communicated with the water inlet pipe through a water pump; the recycling water storage tank is communicated with the filtering solution output pipe through a reflowing pipe; and the reflowing pipe is provided with a control valve. Compared with the prior art, the press filtering washing water recycling and utilizing system for producing the white carbon black is additionally provided with the recycling water storage tank to recycle post-period filter cake washing water; and the recycled water is used for early-stage washing of the next batch of filter cakes, so that the consumption of the water and the sewage discharging amount are reduced, the system is environmentally-friendly and the cost is saved.
Description
Technical field
The present invention relates to the white carbon black production technical field, especially relate to a kind of press filtration washings recycling system for precipitated silica production.
Background technology
That white carbon has is high temperature resistant, do not fire, tasteless, odorless, have series of advantages such as good electrical insulating property, make it can be widely used in many fields such as rubber, agricultural chemical, daily-use chemical industry goods, cementing agent, anti-caking agent, at present, in the precipitated silica production process, when filter press filter cake washs, water after the washing all is to adopt directly to be disposed in the waste water, not only bad for environmental protection, the more important thing is the waste that causes large water gaging.
Summary of the invention
The object of the present invention is to provide a kind of press filtration washings recycling system for white carbon black production, the characteristics that it has water saving, environmental protection and reduces production costs.Effectively solved the problem that exists in the precipitated silica production press filtration operation in the prior art.
The objective of the invention is to be achieved through the following technical solutions:
A kind of press filtration washings recycling system for white carbon black production, it comprises filter press, described filter press connects water inlet pipe and filtrate effluent pipe, be provided with control valve on described water inlet pipe and the filtrate effluent pipe, wherein, described press filtration washings recycling system also comprises the recovery storage tank, and described recovery storage tank is connected with water inlet pipe by water pump, and described recovery storage tank also is connected with the filtrate effluent pipe by return duct, on the described return duct control valve is installed.
Especially, described filter press is the Pneumatic pressure filter, is connected with compressed air inlet pipe and gas outlet on it.
Beneficial effect of the present invention is, described press filtration washings recycling system for white carbon black production has compared with prior art been set up the recovery storage tank, later stage Washing of Filter Cake water is reclaimed, and be reused for the early stage washing of next group filter cake, reduce water consumption and wastewater discharge, environmental protection, saved cost.
Description of drawings
Fig. 1 is the structural representation of the press filtration washings recycling system that is used for white carbon black production that provides of the specific embodiment of the invention 1.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the press filtration washings recycling system that is used for white carbon black production that provides of the specific embodiment of the invention 1.
In the present embodiment, a kind of press filtration washings recycling system for white carbon black production comprises filter press 1 and reclaims storage tank 2, described filter press 1 connects water inlet pipe 3 and filtrate effluent pipe 4, and described filter press 1 is the Pneumatic pressure filter, be connected with compressed air inlet pipe 5 and gas outlet 6 on it, described recovery storage tank 2 is connected with water inlet pipe 3 by water pump 7, and described recovery storage tank 2 also is connected with filtrate effluent pipe 4 by return duct 8.
On described water inlet pipe 3, filtrate effluent pipe 4, compressed air inlet pipe 5, gas outlet 6, the return duct 8 control valve is installed all.
White carbon Washing of Filter Cake process approximately needs 1 hour, sometimes needs to reach 1.5 hours, in first half section washing process, because the washings electrical conductivity is high, impurity content is large, can not reuse, so the control valve of controlling on each pipeline directly discharges from filtrate effluent pipe 4; And along with the prolongation of wash time, the washings electrical conductivity is more and more lower, and at this moment, the control valve on the control piper makes washings flow back into from return duct 8 and reclaims storage tank 2, when the leading portion that carries out next batch of material during the washing stage, pumped into the leading portion washing stage that is used for this batch of material in the water inlet pipe 3 by water pump 7.
Above-mentioned press filtration washings recycling system for white carbon black production reclaims later stage Washing of Filter Cake water, and is reused for the early stage washing of next group filter cake, under the prerequisite that guarantees washing quality, not only reduces the consumption of water and wastewater discharge, environmental protection; And saved cost.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
