Abstract
The utility model discloses a sludge low temperature drying device. A material outlet is arranged at the top of a drier, an air inlet is arranged at the bottom of the drier, and the drier is also provided with a material inlet. The utility model is characterized in that the material inlet is positioned between the air inlet and the material outlet, and a baffle plate is arranged inside the drier, and is positioned between the air inlet and the material inlet, and a plurality of holes are arranged on the baffle plate, therefore forming a net shaped baffle plate, an iron shot is placed on the hole, and the diameter of the iron shot is larger than the diameter of the hole. By adopting the structure, the drier provided by the utility model can dry up the wet sludge in low temperature, thus the energy resource is effectively saved, the burnt odor flavor generated when the sludge is dried in high temperature is avoided, and the surrounding environment is improved.
Description
Technical field
The utility model relates to a kind of sludge dryer, more particularly, relates to a kind of sludge at low temperature drying device.
Background technology
Mud refer to municipal sewage and industrial wastewater through sewage treatment plant handle the biocolloid material of discharging the back or river, mud material or the like is dredged in the lake, this type of moisture percentage in sewage sludge height (about 80%), volume are big, particle is tiny, deep dehydration is difficult, account for a large amount of spaces and produce stench easily, the processing that is unfavorable for mud is disposed and utilization, therefore must utilize the means of sludge dewatering, drying, moisture is separated from mud.Practice both domestic and external shows, after traditional concentrated and shrink PROCESS FOR TREATMENT, the moisture content of mud is difficult to reach below 70%, and economic mechanical dehydration moisture content of the cake also is about 75%, this moment, the calorific value of mud was very low, also needed very big energy expenditure if adopt the means of burning to handle.So reach the deep dehydration of mud, comparatively Jing Ji method is exactly to use heated drying technology and equipment commonly used in the chemical industry operation.
The equipment that current drying mud adopts mainly contains vertical drier and drum dryer, and these two kinds of driers all need a large amount of extra powers it to be heated or logical hot blast, thereby makes mud dehydration under the high temperature heating, and then discharges drier.Mainly there are two defectives in this way: the one, consumed a large amount of energy, and dried mud can be taken away the heat of a part, and this part energy is difficult to reclaim, and utilization rate is very low again; The 2nd, because mud is at high temperature dry, a part of mud can be burnt because of over-heating, gives out unpleasant empyreumatic taste, and environment is on every side impacted.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to operate, sludge at low temperature drying device that labour intensity is low, corrosion-resistant, free from environmental pollution.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Sludge at low temperature drying device of the present utility model, top at drier is provided with discharging opening, bottom at this drier has air inlet, on drier, also have charging aperture, it is characterized in that: described charging aperture is equipped with baffle plate in drier between described air inlet and discharging opening, described baffle plate is between described air inlet and charging aperture, have a plurality of holes on this baffle plate, in described hole, be placed with the diameter iron shot bigger than the diameter in this hole.
The described baffle plate that has a plurality of holes has formed netted.
Described charging aperture is opened the middle part at drier, and this baffle plate is positioned at above the air inlet.
Described drier is a vertical drier.
Owing to adopted said structure, as the low temperature hot blast when air inlet blows into drier, the iron shot that is placed on the baffle plate will be blown up, this moment, wet mud entered drier from the middle part charging aperture of drier, because moisture content height, wet mud is past whereabouts under the effect of gravity, the wet mud that falls can run into the iron shot that is blown up, these iron shots and wet mud bump, at wet mud and iron shot constantly under the collision effect, wet mud is broken into fine granularity, and short grained mud is easy to dehydration in the low temperature hot blast of big air quantity, discharges from the discharging opening of drier at last, mud is dry at low temperatures so the utility model has been realized wetting, saved the energy effectively, the empyreumatic taste of having avoided mud when high temperature drying, to produce, the environment around having improved; In addition, the utility model is simple in structure, easy to operate, labour intensity is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments to further detailed explanation of the utility model.
Fig. 1 is the schematic diagram of the utility model sludge at low temperature drying device.
The specific embodiment
As shown in Figure 1, it is the schematic diagram of the utility model sludge at low temperature drying device.Be provided with discharging opening 6 at the top of drier 1, have air inlet 2 in the bottom of this drier 1, drier 1 also has charging aperture 5, and this charging aperture 5 is out that at the middle part of drier 1, wherein drier 1 is a vertical drier.Baffle plate 3 is housed in drier 1, described baffle plate 3 be to be between described air inlet 2 and the charging aperture 5, thereby having a plurality of holes on this baffle plate 3 makes baffle plate 3 form netted baffle plate, in described hole, be placed with the diameter iron shot 4 bigger, thereby iron shot 4 can not fall down from the hole of baffle plate 3 than the diameter of respective aperture.
When the utility model uses, as the low temperature hot blast when air inlet 2 blows into drier 1, the iron shot 4 that is placed on the baffle plate 3 will be blown up, this moment, wet mud entered drier 1 from the charging aperture 5 at drier 1 middle part, because wet moisture percentage in sewage sludge height, wet mud is past whereabouts under the effect of gravity, the wet mud that falls runs into the iron shot 4 that is blown up, these iron shots 4 bump with wet mud, under wet mud and iron shot 4 continuous collision effects, wet mud is broken into fine granularity, and short grained mud is easy to dehydration in the low temperature hot blast of big air quantity, discharge from the discharging opening 6 of drier 1 at last, thereby realized effect of the present utility model.
In a word,, should illustrate that obviously those skilled in the art can carry out various variations and remodeling though the utility model has been enumerated above-mentioned preferred implementation.Therefore, unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included within the protection domain of the present utility model.
