Description
Technical field
A kind of defoaming device of the utility model relates to a kind of defoaming device that adopts the sludge at low temperature carbonization technique to dispose the foam that produces in sewage work's dewatered sludge process.
Background technology
During 12 (2011 to 2015), in water ratio 80%, the mud total amount that national annual sewage work produces reaches about 3,000 ten thousand tons, if can not properly dispose, can cause serious secondary pollution to environment.Along with the gradually attention of people to sludge disposal, increasing sludge disposal technology is rapidly developed, and mainly contains sludge composting, Sludge landfill, sludge incineration, sludge drying, sludge high temperature carbonization and sludge at low temperature carbonization etc.
The mud that sewage work produces, because the existence of biomass cell, even carried out concentrated, dehydration, moisture percentage in sewage sludge is still up to 75-82%.When adopting sludge at low temperature carbonization technique lignin-sludge, biomass cell cracking under the condition of high temperature, high pressure in the mud, so that the moisture that exists with forms such as internal water, planar water, capillary waters in the mud is separated out, adopt again centrifuge to dewater, can access the solid substance of water ratio about 50%, 75% moisture is removed in this process, has realized minimizing, the stabilization and innoxious of mud, is a kind of sludge disposal new technology with wide market outlook.But in dehydration, the lysate after the centrifuge dehydration can produce a large amount of foams, in order not affect the normal operation of carbonization factory, must eliminate these foams.At present, technology commonly used is to use defoamer, and the method offsets foam-expelling and has certain effect, but processing cost is higher, and can produce new pollution when eliminating foam.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of low cost, foam and defoaming device easy and simple to handle are eliminated in pollution-free, mechanize.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of defoaming device, comprise and inhale bubble blower fan, cylindrical shell, stainless (steel) wire and shredded coconut meat layer of fibers, be provided with up and down two-layer stainless (steel) wire in the inside of described cylindrical shell, between two-layer stainless (steel) wire, be filled with the shredded coconut meat layer of fibers, be provided with air channel and inlet pipe at the top of cylindrical shell, be provided with opening for feed in the outer lower portion of cylindrical shell, be provided with discharge port in the bottom of cylindrical shell;
One end in described air channel is communicated with cylindrical shell, and the other end is the air outlet, is provided with to inhale the bubble blower fan in the air channel.
Be provided with the air inlet adjustment valve on the described inlet pipe.
Described suction bubble blower fan is centrifugal fan.
The sieve diameter of described two-layer stainless (steel) wire is 1mm-3mm, and screen cloth thickness is 5-10mm.
The fibrolaminar laying gap size of described shredded coconut meat is 2mm-4mm, and the fibrolaminar laying depth of shredded coconut meat is 100mm-150mm.
The utility model is compared with existing technology has following beneficial effect.
One, high with the existing cost that adopts, there is the defoamer of pollution to compare, the utility model adopts the mechanize froth breaking, after the lysate after the centrifuge dehydration enters cylindrical shell, utilize the foam of inhaling in the bubble blower fan absorption lysate, foam is at the stainless (steel) wire that passes through successively lower floor in the process of inhaling the rising of bubble blower fan direction, the stainless (steel) wire on shredded coconut meat layer of fibers and upper strata, foam is broken under their extruding, this process can be broken with most foams, and through lower floor's stainless (steel) wire, the a small amount of foam that still exists after the extruding of shredded coconut meat layer of fibers and upper strata stainless (steel) wire can rise to be inhaled the bubble blower fan and is inhaled the impeller of bubble blower fan and break, foam after the last fragmentation is got back to cylinder body bottom under action of gravity, discharge from discharge port, this mechanize froth breaking is easy to operate, and cost is low, do not pollute;
When inhaling the lasting foam of drawing in the lysate of bubble blower fan, the air in the cylindrical shell can reduce gradually, for regulating the vacuum tightness in the cylindrical shell, inputs atmosphere from inlet pipe to cylindrical shell, guarantees that the utility model can continuous and steady operation.
Two, by the air inlet adjustment valve is set in inlet pipe, can better regulate the atm number of input cylindrical shell, so that the utility model use is more stable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is work synoptic diagram of the present utility model.
Among the figure, 1 is the air outlet, and 2 for inhaling the bubble blower fan, and 3 is the air channel, and 4 is inlet pipe, 5 is the air inlet adjustment valve, and 6 is cylindrical shell, and 7 is stainless (steel) wire, and 8 is the shredded coconut meat layer of fibers, and 9 is opening for feed, 10 is discharge port, and 11 are suction pump, and 12 is liquid storage tank, and 13 is Deodorising, and 14 is whizzer.
Embodiment
As shown in Figure 1 and Figure 2, a kind of defoaming device, comprise and inhale bubble blower fan 2, cylindrical shell 6, stainless (steel) wire 7 and shredded coconut meat layer of fibers 8, be provided with up and down two-layer stainless (steel) wire 7 in the inside of described cylindrical shell 6, between two-layer stainless (steel) wire 7, be filled with shredded coconut meat layer of fibers 8, be provided with air channel 3 and inlet pipe 4 at the top of cylindrical shell 6, be provided with opening for feed 9 in the outer lower portion of cylindrical shell 6, be provided with discharge port 10 in the bottom of cylindrical shell;
