Abstract
The utility model discloses a device for stabilizing sludge with lime. The device mainly comprises a dewatered sludge tank, a feeding screw conveyor, a material mixing device, a lime silo, a curing agent silo, metering and charging conveyors, a drum dryer, a granulator, an inclined discharging conveyor, a dust collector and a waste gas treatment tower. The device has the beneficial effects that the sludge is quickly heated with chemical heat emitted during hydrolysis reaction of a curing agent added to the material mixing bin, thus effectively reducing energy consumption needed by sludge evaporation; bacteria protomer is effectively eradicated and the risk of bacteria protomer regeneration is avoided; and elements, such as calcium, iron and aluminium, added in a sludge drying process are accepted by many building material products and the application of recycling of resources is wide, so that harmless and reduction recycling of sludge forms a virtuous circle.
Description
Technical field
The utility model relates to a kind of mud lime stabilization makeup to be put, and belongs to the environmental protection technical field of sludge treatment.
Background technology
Along with the raising of wastewater treatment rate, producing sludge quantity increases greatly, and the sludge treatment handling problems day by day highlights, and becomes the difficult problem that water treatment field faces.A large amount of excess sludges will discharge in sewage work, the mud of enormous amount need be done further processing, if mud can not get reasonable processing, to cause secondary pollution, the processing disposal costs of sewage sludge is higher, in whole construction costs of sewage work, account for 20%～50% for the treatment of mud.The composition of sewage sludge is very complicated, except containing a large amount of moisture, also contains a large amount of useful resources.Have multiplely at present for the municipal sludge treatment process, landfill, burning and comprehensive utilization are generally arranged, but before recycling, need carry out pre-treatment to mud, nurse one's health, comprise concentrated, dehydration, drying.More existing sludge drying techniques have the moisture content that adopts in the steam heating evaporation mud, have shortcomings such as energy consumption is higher, generation foul waste gas.Mud through after the mummification can apply to land reclamation, and how building materials utilization etc. reduce the water ratio of mud, and this is the vital task of sludge treatment, also should avoid problem of secondary pollution in drying process.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide a kind of mud lime stabilization makeup to put, having stirring, batch mixing, heating, sterilization, drying and granulating is the sludge drying device of one, utilize the chemical heat heating, energy consumption is lower, and can reduce moisture percentage in sewage sludge and reach the recycling requirement, effectively avoid the characteristics of problem of secondary pollution.
The purpose of this utility model is achieved through the following technical solutions: a kind of mud lime stabilization makeup is put, and it is characterized in that: mainly be made up of dewatered sludge pond, feed auger transfer roller, blending device, lime warehouse, solidifying agent warehouse, metered charge transfer roller, rotary drum dryer, prilling granulator, discharging incline conveyer, cleaning apparatus and exhaust gas treating tower; Be provided with the feed auger transfer roller between described dewatered sludge pond and the blending device; Between described blending device and the lime warehouse, and be provided with the metered charge transfer roller between blending device and the solidifying agent warehouse; The feed end of described rotary drum dryer connects blending device.
Described prilling granulator top waste gas outlet connects cleaning apparatus and exhaust gas treating tower successively with pipeline.
Further, an end of described discharging incline conveyer connects prilling granulator.
In sum, the beneficial effects of the utility model are: utilize the chemical heat of emitting at unslaked lime and the solidifying agent generation hydrolysis reaction of blending bunker adding rapidly with the mud heating, reached the temperature required of water evaporation, effectively hang down mud and evaporate required energy consumption; Because the drum dried built-in temperature can reach 100 ℃, effective eliminating bacteria substance, and do not have the risk that the bacterium substance is regenerated; The calcium that increases in the sludge drying treating processes, iron, aluminium element are admitted by many plastics products for building, and resource utilization recycling of many uses makes sewage sludge harmlessness, minimizing and resource utilization recycling form benign cycle; Adopt exhaust gas treating tower to handle water vapor and the tail gas of drying machine, effectively avoid waste gas to produce secondary pollution.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment: as shown in Figure 1, the utility model mainly is made up of dewatered sludge pond 1, feed auger transfer roller 2, blending device 3, lime warehouse 4, solidifying agent warehouse 5, metered charge transfer roller 6, rotary drum dryer 8, prilling granulator 10, discharging incline conveyer 11, cleaning apparatus 12 and exhaust gas treating tower 13; Be provided with feed auger transfer roller 2 between described dewatered sludge pond 1 and the blending device 3; Between described blending device 3 and the lime warehouse 4, and be provided with metered charge transfer roller 6 between blending device 3 and the solidifying agent warehouse 5; The feed end of described rotary drum dryer 8 connects blending device 3.
Described prilling granulator 10 top waste gas outlets connect cleaning apparatus 12 and exhaust gas treating tower 13 successively with pipeline.
Further, an end of described discharging incline conveyer 11 connects prilling granulator 10.
Principle of work of the present utility model: after sludge of sewage treatment plants is carried out thickening, water ratio is that 70～80% mud enters dewatered sludge pond 1, feed auger transfer roller 2 promotes mud and is transported in the blending device 3, and in blending device 3, add certain amount of calcined lime and solidifying agent, be transported in the rotary drum dryer 8 by blending device 3, the abundant hybrid concurrency biochemistry of water in rotary drum dryer 8 in unslaked lime and solidifying agent and the mud closes reaction, discharge a large amount of heat energy, moisture content in the mud is evaporated in a large number, thermometer 9 detects the temperature in the rotary drum dryer 8 in real time, adopt cleaning apparatus 12 and exhaust gas treating tower 13 to handle water vapor and the tail gas of drying machine, effectively avoid waste gas to produce secondary pollution.Dried mud is transported to mud after the mummification in the dewatered sludge storehouse with discharging incline conveyer 11 by after prilling granulator 10 granulations.Because temperature can reach 100 ℃ in the rotary drum dryer 8, effective eliminating bacteria substance, and do not have the risk that the bacterium substance is regenerated; The calcium that increases in the sludge drying treating processes, iron, aluminium element are admitted by many plastics products for building, and resource utilization recycling of many uses makes sewage sludge harmlessness, minimizing and resource utilization recycling form benign cycle.
As mentioned above, just can realize the utility model preferably.
