Abstract
The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to a sewage hot air concentrator. The sewage hot air concentrator comprises a sewage pool and a heat exchange tank, wherein the heat exchange tank is arranged at the top of the sewage pool and communicated with an inner cavity of the sewage pool; a steam discharging port is formed in the top of the heat exchange tank, and a hot air inlet is formed in the bottom of a side wall; the sewage hot air concentrator further comprises a hot air fan and a circulating pump; the hot air fan is connected to the hot air inlet through a pipeline; an inlet of the circulating pump is communicated to the sewage pool, and a water feeding pipe is arranged at an outlet of the circulating pump; and an end part of the water feeding pipe is located at the top of an inner cavity of the heat exchange tank, and a plurality of spray nozzles are arranged. The sewage hot air concentrator is simple in structure, small in occupied area and easy to set up, operate and manage; and hot air is used as a medium heated directly and exchanges heat with sprayed sewage, the heat utilization efficiency is high, and energy is saved.
Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, relates in particular to a kind of sewage hot blast thickener.
Background technology
At electroplating industry, along with the carrying out of production process, usually can produce a large amount of waste liquids, contain the additive of plurality of heavy metal ion and auxiliary electroplating reaction in these waste liquids, if the impact of directly being discharged environment will be huge.Generally, the enterprise that is engaged in plating all can build the liquid waste disposal facility and reclaims the useful component in electroplate liquid and reduce as far as possible pollutent wherein, realizes that " zero release " is ultimate target.In order to realize zero release, concentrated, the minimizing waste liquid amount of waste liquid being carried out to the degree of depth are the first steps.In prior art, the general water evaporation concentration equipment that adopts is concentrated waste liquid, and this type of device structure is complicated, energy consumption is higher.There are the problems referred to above in other industry equally to the processing of sewage, waste water.
The utility model content
The utility model provides a kind of simple in structure, sewage hot blast thickener that energy consumption is low for solving the technical problem existed in known technology.
The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is: the heat exchange tank that sewage hot blast thickener comprises sewage lagoon and is located at its top and communicates with its inner chamber; The bottom that is provided with steam outlet, sidewall at the top of described heat exchange tank is provided with hot-wind inlet; Also comprise the calorifier that is connected to described hot-wind inlet by pipeline; Also comprise recycle pump, its entrance is communicated to described sewage lagoon, its outlet is provided with induction pipe, and the end of described induction pipe is positioned at the top of described heat exchange tank inner chamber and is provided with a plurality of nozzles.
Advantage of the present utility model and positively effect are: sewage hot blast thickener of the present utility model is simple in structure, floor space is little, be easy to build realization, also easy handling management, adopt the sewage heat change of hot blast as direct-fired medium and spray, efficiency of utilization is high, saved the energy.
Preferably: also be provided with hot blast and distribute card in described heat exchange tank, between described hot-wind inlet and described nozzle.
Preferably: between the top of described heat exchange tank inner chamber, described steam outlet and described nozzle, also be provided with the dehydration packing layer.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, steam outlet; 2, dehydration packing layer; 3, induction pipe; 4, recycle pump; 5, sewage lagoon; 6, calorifier; 7, hot-wind inlet; 8, hot blast distributes card; 9, heat exchange tank; 10, nozzle.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the heat exchange tank 9 that the utility model comprises sewage lagoon 5 and is located at its top and communicates with its inner chamber, both inner chambers are issued a general order to mutually and are sprayed the rear concentrated sewage backflow of heat exchange.
The bottom that is provided with steam outlet 1, sidewall at the top of heat exchange tank 9 is provided with hot-wind inlet 7.Also comprise the calorifier 6 that is connected to hot-wind inlet 7 by pipeline.
Also comprise recycle pump 4, its entrance is communicated to sewage lagoon 5, its outlet is provided with and send water 3 pipes, and the end of this induction pipe 3 is positioned at the top of heat exchange tank 9 inner chambers and is provided with a plurality of nozzles 10.
In this example, in order to make hot blast, in the inner chamber of heat exchange tank 9, evenly rise, produce better heat transfer effect, also be provided with hot blast and distribute card 8 between hot-wind inlet 7 and nozzle 10.It is tabular that hot blast distributes card 8, is provided with the pore that a plurality of hot wind supplies pass through.
In this example, for the sewage drop of the liquid state that will upwards be taken out of by hot blast is held back, prevent that running out of what pollute, make in steam outlet 1 discharge by steam outlet 1 is pure water vapor, also is provided with the packing layer 2 that dewaters between top, steam outlet 1 and the nozzle 10 of heat exchange tank 9 inner chambers.This dehydration packing layer 2 stays liquid sewage, again, to falling in sewage lagoon 5, makes water vapor pass through simultaneously, upwards via steam outlet 1, discharges.
The working process of this example: the hot blast that calorifier 6 produces is entered the inner chamber of heat exchange tank 9 by hot-wind inlet 7, via hot blast, distribute the rear even rising of card 8.Simultaneously, recycle pump 4 is delivered to nozzle 10 place's sprays downwards by the sewage in sewage lagoon 5 through induction pipe 3.Hot blast upwards and downward sewage droplets mixing heat exchange, it is together up in company with hot blast that sewage drop heat absorption moisture wherein becomes water vapor, and other composition is back to downwards in sewage lagoon 5.So move in circles, the sewage in sewage lagoon 5 is concentrated, and total amount reduces.
