Abstract
The utility model discloses a device for treating calcium mud and recovering nitrate water, and relates to a device for treating calcium-magnesium mud and recovering nitrate water in the preparation of anhydrous sodium sulfate. The device comprises a nitrate water reaction clarification device, a mud clarification device, a valveless filter and a rotary drum vacuum filter, wherein after being clarified by the nitrate water reaction clarification device, the supernatant liquid is filtered by the valveless filter, and the nitrate water is recovered; after being clarified by the nitrate water reaction clarification device, the lower turbid liquid is clarified by the mud clarification device again, the supernatant liquid is filtered by the valveless filter, and the nitrate water is recovered; the lower mud is filtered by the rotary drum vacuum filter, the produced clear liquid is filtered by the valveless filter, and the nitrate water is recovered; and the produced calcium-magnesium mud enters the subsequent processing. The device for treating the calcium mud and recovering the nitrate water is low in environmental pollution, can effectively treat the calcium-magnesium mud and recover the nitrate water and is high in quality of the recovered nitrate water.
Description
Technical field
The utility model relates to the device that calcium magnesium mud is handled and glass gall reclaims in the anhydrous sodium sulphate preparation.
Background technology
At present, mainly be divided into two kinds of methods for the processing of calcium mud and the recovery of glass gall.First method, former glass gall is through the plate-type heat exchanger preheating, preheating former glass gall is later beaten to the preheating bucket, and then beat to reacting settling tank, add soda ash, caustic soda, flocculation agent simultaneously, open and stir, clarification afterreaction bucket lower floor mud is beaten to the calcium mud sump by slush pump, supernatant liquid filters the back by swash plate settler and husky filter and reclaims glass gall, the calcium mud of swash plate settler also drains into the calcium mud sump, the calcium mud of calcium mud sump separates by plate-and-frame filter press then, and the calcium body refuse is transported to barrow, and the glass gall after the separation enters wastewater disposal basin and beats to the mine by sump pump at last; Second method, the filtering separation by plate-and-frame filter press not, and the calcium magnesium mud of reaction container and swash plate settler is at first drained into the calcium mud sump, directly logical sump pump is beaten to the mine and is outwelled then.All there are many defectives in two kinds of methods: environmental pollution is big, and the glass gall rate of recovery is low, and it is poor to reclaim glass gall foreign matter content high quality; Sump pump breaks down in process of production easily, maintenance cost height, and easy contaminate environment, and the glass gall wastage is big.In addition, plate and frame(type)filter press weight of equipment and volume are big, adopt and the sludge dewatering equipment of the type adopts the intermitten service mode, the time produce the 50kg/h solid, throughput is less; And this equipment also has the special messenger of need guard, and automatism is relatively poor; Movable part is many, instability; The facility investment height; Maintenance difficulty is big; Operation is comparatively complicated, the palpus personal management; Shortcomings such as work-ing life is short; Simultaneously, the filter frame material inlet stops up easily, and filter cake is difficult for taking out, and can not move continuously, and treatment capacity is little, and operating pressure is low, and common material side plate is not withstand voltage, easily break plate, and filter cloth consumption is big, and sheet frame is difficult to accomplish unmanned, and filter cloth usually needs the labor cleaning.
The utility model content
The purpose of this utility model is: it is little to propose a kind of environmental pollution, can more effective processing calcium magnesium mud and reclaim glass gall, and reclaim the high calcium mud of glass gall quality and handle and the glass gall retrieving arrangement.
The utility model purpose realizes by following technical proposals:
A kind of calcium mud is handled and the glass gall retrieving arrangement, comprise glass gall reaction clarifying plant, the mud clarifying plant, valveless water filter device and rotating drum vacuum filtration device, the supernatant liquid outlet of described glass gall reaction clarifying plant is communicated with the entrance of described valveless water filter device, the outlet of described valveless water filter device is communicated with smart glass gall storing unit, the turbid liquid outlet of the lower floor of described glass gall reaction clarifying plant is communicated with described mud clarifying plant entrance, the supernatant liquid outlet of described mud clarifying plant is communicated with the entrance of described valveless water filter device, lower floor's mud outlet of described mud clarifying plant is communicated with described rotating drum vacuum filtration device entrance, the purified liquor outlet of described rotating drum vacuum filtration device is communicated with described valveless water filter device entrance, and the calcium magnesium mud outlet of described rotating drum vacuum filtration device is connected with calcium magnesium mud aftertreatment device.
As optimal way, the turbid liquid outlet of the lower floor of described glass gall reaction clarifying plant is communicated with described mud clarifying plant entrance by slush pump.
The beneficial effects of the utility model: according to product characteristics and the various apparatus features of different steps separating and filtering, it is divided into three-stage filtration separates, and specific corollary apparatus is combined with specific separation phase, realize separating and filtering effect and the device maximum using of synergy the best down: the supernatant liquid recovery glass gall after the valveless water filter device filters after the glass gall reaction clarification of one-level; The turbid liquid of lower floor after the glass gall reaction clarification of secondary is through after clarifying again, and its supernatant liquid reclaims glass gall after described valveless water filter device filters; Lower floor's mud after three grades the clarification again is after the rotating drum vacuum filtration device filters, and the clear liquid of output reclaims glass gall after described valveless water filter device filters, and the calcium magnesium mud of output enters subsequent disposal.Its final environmental pollution is little, efficient recovery glass gall more, reclaim glass gall quality height, and reduced investment in production equipment cost and maintenance cost, saved plant area the occupation of land space, produce in good filtration effect, filtration yield is big, operate more convenient, as to have solved sump pump obstruction problem, be conducive to produce; More economical.
Description of drawings
Fig. 1 is the device schematic flow sheet of the utility model embodiment.
Embodiment
Following non-limiting examples is used for explanation the utility model.
As shown in Figure 1, a kind of calcium mud is handled and the glass gall retrieving arrangement, comprise glass gall reaction clarifying plant (glass gall reaction settling tank), mud clarifying plant (mud tank), valveless water filter device and rotating drum vacuum filtration device, the supernatant liquid outlet of glass gall reaction settling tank is communicated with the entrance of valveless water filter device, the outlet of valveless water filter device is communicated with smart glass gall storing unit (smart glass gall bucket), the turbid liquid outlet of the lower floor of glass gall reaction settling tank is communicated with the mud tank entrance by slush pump, the supernatant liquid outlet of mud tank is communicated with the entrance of valveless water filter device, lower floor's mud outlet of mud tank is communicated with rotating drum vacuum filtration device entrance, the purified liquor outlet of rotating drum vacuum filtration device is communicated with valveless water filter device entrance, and the outlet of the calcium magnesium mud of rotating drum vacuum filtration device is discharged and carried out subsequent disposal behind the calcium magnesium mud (as through carrying, transport after the stacking).
