Abstract
The utility model relates to a kind of waste recovery systems of filter-press, it is characterized in that: it comprises filter-press (1), the liquid outlet of described filter-press (1) is connected with the top inlet of surge tank (2), the drain pipe of described surge tank (2) bottom is connected with the liquid return hole of filter-press (1), and the drain pipe of surge tank (2) bottom also separates arm and is connected with the inlet of mother liquor cooler (6) with circulation alkali flow container (3), mother liquor flash tank (5).The exhaust outlet of described filter-press (1) is connected with scrubbing tower (8) by pipeline, and the top of described scrubbing tower (8) is provided with blast pipe (9), scrubbing tower (8) bottom and recycling can (10).The waste recovery systems of this filter-press can make full use of salkali waste, reduces cost of sewage disposal, avoids air pollution, reduce production cost.
Description
Technical field
The utility model relates to a kind of waste recovery systems of filter-press.
Background technology
Filter-press needs when alkali cleaning to use a large amount of alkali lye; and have a large amount of salkali waste after alkali cleaning and emit; these salkali waste usually directly can be discharged in sewage disposal system and carry out sewage disposal; but so just do not make full use of salkali waste; improve the cost of sewage disposal, improve production cost.Pressure filtration chance gives off some gases in air simultaneously, and carried some PTA solid particles in these gases secretly, these PTA solid particles directly discharge and not only cause air pollution, also waste PTA raw material simultaneously, improve production cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one to make full use of salkali waste, reduces cost of sewage disposal, avoids air pollution, reduce the waste recovery systems of the filter-press of production cost.
The purpose of this utility model is achieved in that
The waste recovery systems of the utility model filter-press, comprise filter-press, the liquid outlet of described filter-press is connected with the top inlet of surge tank, drain pipe bottom described surge tank is connected with the liquid return hole of filter-press, drain pipe bottom surge tank also separates arm and circulation alkali flow container, mother liquor flash tank is connected with the inlet of mother liquor cooler, the liquid outlet of described circulation alkali flow container is connected by the inlet of pump with mother liquor filter, the liquid outlet of described mother liquor cooler is connected by the liquid return hole of return duct with surge tank side, the exhaust outlet of described filter-press is connected with scrubbing tower by pipeline, the top of described scrubbing tower is provided with blast pipe, wash tower bottoms and recycling can.
Compared with prior art, the beneficial effects of the utility model are:
The waste recovery systems of this filter-press is by arranging surge tank, and surge tank is carried out follow-up use after the salkali waste that filter-press is collected passes into circulation alkali flow container, mother liquor filter, mother liquor flash tank, again circulated in salkali waste cooling for reflux to surge tank by mother liquor cooler simultaneously, salkali waste in filter-press can be utilized fully like this, reduce cost of sewage disposal, reduce production cost; After filter-press, add scrubbing tower simultaneously, can the gas of discharging in filter-press be sprayed, thus by PTA powder collection in recycling can, thus save PTA raw material, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the waste recovery systems of the utility model filter-press.
Wherein: filter-press 1, surge tank 2, circulation alkali flow container 3, mother liquor filter 4, mother liquor flash tank 5, mother liquor cooler 6, return duct 7, scrubbing tower 8, blast pipe 9, recycling can 10.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of waste recovery systems of filter-press, comprise filter-press 1, the liquid outlet of described filter-press 1 is connected with the top inlet of surge tank 2, drain pipe bottom described surge tank 2 is connected with the liquid return hole of filter-press 1, drain pipe bottom surge tank 2 also separates arm and circulation alkali flow container 3, mother liquor flash tank 5 is connected with the inlet of mother liquor cooler 6, the liquid outlet of described circulation alkali flow container 3 is connected by the inlet of pump with mother liquor filter 4, the liquid outlet of described mother liquor cooler 6 is connected by the liquid return hole of return duct 7 with surge tank 2 side, the exhaust outlet of described filter-press 1 is connected with scrubbing tower 8 by pipeline, the inner spray downwards of this scrubbing tower 8 is to collect the PTA particle carried secretly in gas, in the liquid that PTA particle is incorporated bottom scrubbing tower 8, the top of described scrubbing tower 8 is provided with blast pipe 9 for emission gases, be connected with recycling can 10 for depositing the liquid being entrained with PTA particle collected bottom scrubbing tower 8.
The waste recovery systems of this filter-press is by arranging surge tank 2, and surge tank 2 is carried out follow-up use after the salkali waste that filter-press 1 is collected passes into circulation alkali flow container 3, mother liquor filter 4, mother liquor flash tank 5, by mother liquor cooler 6, salkali waste cooling for reflux is again circulated in surge tank 2 simultaneously, salkali waste in filter-press 1 can be utilized fully like this, reduce cost of sewage disposal, improve production cost; After filter-press 1, add scrubbing tower 8 simultaneously, can the gas of discharging in filter-press be sprayed, thus by PTA powder collection in recycling can 10, thus save PTA raw material, reduce production cost.
