Description
Technical Field
The utility model relates to a preprocessing device used before sludge incineration.
Background
Along with the acceleration of urbanization process and the rapid development of industrial production in China, the discharge amount of urban industrial wastewater and domestic sewage is increasing day by day. At present, the process of drying and then incinerating sludge becomes a main process for treating sludge in developed countries, and is also a main development direction for treating sludge in China. The sludge is dehydrated into solid sludge and then is transported to an incineration plant for disposal. The current disposal method is to mix the sludge with other solid waste materials and convey the mixture into an incinerator for incineration through a grab bucket or a screw pump. Because the amount of sludge to be treated in the market is increased, if the sludge is conveyed into the incinerator by a grab bucket or a screw pump, the prior treatment equipment cannot meet the treatment amount, and the integral smoke of the incinerator is easy to exceed the standard.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect and provide a preprocessing device for before sludge incineration, it can accelerate the handling capacity of mud, makes the material can burn completely in burning furnace to can not arouse to burn burning furnace flue gas problem that exceeds standard.
The purpose of the utility model is realized like this: a pretreatment device used before sludge incineration comprises a sludge conveyor, a stirring tank, a wastewater storage tank, a wastewater pump, a colloid mill, a liquid pump and a spray gun; wherein the content of the first and second substances,
the outlet of the sludge conveyor is connected with the inlet of the stirring tank;
the waste water liquid storage tank is connected with an inlet of the stirring tank through a waste water conveying pipeline;
the waste water pump is arranged on the waste water conveying pipeline;
the inlet of the colloid mill is connected with the outlet of the stirring tank through a pipeline;
the spray gun is connected with an outlet of the colloid mill through a liquid pipeline;
the liquid pump is mounted on the liquid conduit.
The pretreatment device used before sludge incineration is characterized in that the output port of the sludge conveyor is connected with the inlet of the stirring tank through the discharging hopper.
The utility model discloses a preprocessing device for before sludge incineration has following characteristics: form the slurry through mixing mud and waste water at the agitator tank, reentrant colloid mill carries out the shearing action, forms liquid, gives the spray gun through the liquid pump at last, atomizes the back by the spray gun and sprays in the incinerator, makes the material can burn completely in burning furnace to can not arouse to burn burning furnace flue gas problem that exceeds standard. The utility model can accelerate the sludge treatment.
Drawings
FIG. 1 is a schematic structural diagram of a pretreatment device used before sludge incineration.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the pretreatment device for sludge before incineration of the present invention comprises a sludge conveyor 1, a stirring tank 4, a wastewater storage tank 2, a wastewater pump 3, a colloid mill 5, a liquid pump 6 and a spray gun 7; wherein the content of the first and second substances,
the outlet of the sludge conveyor 1 is connected with the inlet of the stirring tank 4 through a discharging hopper 40;
the waste water liquid storage tank 2 is connected with an inlet of the stirring tank 4 through a waste water conveying pipeline;
the waste water pump 3 is arranged on the waste water conveying pipeline;
an inlet of the colloid mill 5 is connected with an outlet of the stirring tank 4 through a pipeline;
the atomizing spray gun 7 is connected with the outlet of the colloid mill 5 through a liquid pipeline;
the liquid pump 6 is mounted on the liquid conduit.
The utility model discloses a preprocessing device for before sludge incineration stirs the mixture earlier with mud and waste water according to the ratio of setting for in agitator tank 4 at the during operation, and the material transport after the misce bene again advances colloid mill 5. In the colloid mill 5, through higher rotational speed, at the fixed rotor clearance of setting for, the material realizes dispersion and smashing under the friction state, then sends the material that disperses to the spray gun through the liquid pump and carries out atomization process, sends to the burning furnace by the spray gun at last, makes the material can burn completely in burning furnace.
The utility model discloses a preprocessing device for before sludge incineration has following characteristics: form the slurry through mixing mud and waste water at the agitator tank, reentrant colloid mill carries out the shearing action, forms liquid, gives the spray gun through the liquid pump at last, atomizes the back by the spray gun and sprays in the incinerator, makes the material can burn completely in burning furnace to can not arouse to burn burning furnace flue gas problem that exceeds standard. The utility model can accelerate the sludge treatment.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
