The mechanical dehydration module is composed of a high pressure pump and a plate frame filter press; the dry powder carrier hardening and tempering module is composed of a mixer and a stirring machine. The multi-purpose continuous type sludge treatment system of the utility model realizes the moving type treatment way of dispersing the sludge, and reduces the pollution to the environment, simultaneously the sludge is changed into the resource and the resource realization process of the sludge is realized. And the investment cost of the whole process is few, and the operating cost is low.

Description

Multi-functional continous way sludge treating system

Technical field

The utility model belongs to the sludge treatment device technical field, is specifically related to a kind of treatment system that is applied in city sewage and sludge, river course and lake dredging up mud.

Background technology

Municipal sewage treatment is built up in each city, the whole nation and is put into operation; this has played active effect to the water pollution problems that prevents China; but the mud that forms in the sewage treatment process has brought environmental pollution again; therefore aspect the protection environment, the processing of municipal sludge is become a problem of needing solution badly again.

The method of disposal of mud mainly contains soil utilization, landfill, burning, biochemical treatment and topples over and throw sea etc. at present.The method that lake dredging mud mainly adopts interim heap to bury; this not only needs enough spaces and necessary environment protection means; add transportation; make processing costs higher; and be good at finding at peri-urban and be fit to space and the place that heap buries mud, the secondary environmental pollution of Chan Shenging and problem such as land occupations is sharp-pointed day by day in a large number therefrom.Although, incinerating method is attempted to adopt in some place, make sludge reduction, but sludge incineration facility investment volume height, energy-output ratio is big, the working cost costliness, the cost that sludge incineration per ton is handled adds that mud can bring pollution to atmospheric environment when burning, according to the present situation of China generally more than 400 yuan, sludge incineration is handled and is difficult to economically bear, and is ripe not enough technically.At this situation, develop advanced processing and be provided with extremely urgent.

The utility model content

In order to overcome the deficiencies in the prior art, provide a kind of processing mud efficient height, working cost low, can reduce the multi-functional continous way sludge treating system of environment mud.

The utility model is achieved in that

A kind of multi-functional continous way sludge treating system, this system comprises the mud storage tank successively, the modified pre-processing module that is used for modified sludge components and is connected with the mud storage tank, in the mechanical dehydration module that is provided with on the modified pre-processing module through importing after the modified pre-treatment, be connected with the mechanical dehydration module and mud cake behind the mechanical dehydration can be delivered to and with the dry powder carrier modifying module of mechanical dehydration module, in dry powder carrier modifying module one side and by the irradiation modules of dry powder carrier modifying module controls mud inlet, be arranged on the irradiation modules top and can and operate control module the dried mud isolating separation module of process; Described mechanical dehydration module is made of high-pressure pump and plate-and-frame filter press, and high-pressure pump is delivered to plate-and-frame filter press with mud, realizes the dehydration of mud under the effect of mechanical pressure.Described dry powder carrier modifying module is made up of mixing tank and stirrer, the mud low through higher mud of the water ratio of mechanical dehydration and the dry water ratio that then comes out from cyclonic separator mixes in mixing tank, under the agitator effect it is mixed then.

Described separation module is a cyclonic separator.

Be connected by conveying belt between described mechanical dehydration module and the dry powder carrier modifying module, belt conveyor has weighing belt simultaneously, and weighing belt is used to respond to the amount of mud cake behind the mechanical dehydration.

Described irradiation modules is a revolving drier.

Described separation module is connected with the sack cleaner that is used for removing tail gas mud.

The utility model compared with prior art, the present invention is by a kind of successive sludge treatment technique that is combined to form of technical modules such as mud storage tank, modified pre-processing module, mechanical dehydration module, dry powder carrier modifying module, irradiation modules, separation module and operation control module, it is few that the technology that combines has the facility investment expense, sludge treatment is satisfactory for result, does not influence advantages such as environment; Whole process combination is convenient to the portable dispersive mud of handling, and the day output of total system mud reaches 50 tons, is fit to the processing that some mud disperse occasion, as channel cleanout, also is fit to the mud that 100,000 tons of sewage works of supporting processing produce.The utility model has realized disperseing the portable treating method of mud, has reduced mud to the pollution that environment brings, and simultaneously mud is turned waste into wealth, and realizes the resource utilization process of mud.And the investment cost of whole technology is few, and process cost is low.

Embodiment

As shown in Figure 1, mud is introduced into mud storage tank 1, the mud that comes out from the mud storage tank enters the modified pre-processing module 2 of mud, in module 2, add a certain amount of mud adjusting material and water and be used to regulate the flowing property of the composition and the mud of mud, import the mechanical dehydration module through modified pretreated mud by high-pressure pump, sludge quantity by mechanical dehydration is responded to by weighing belt 3, mud cake is delivered to sludge dry powder carrier modifying module by belt behind the mechanical dehydration, under the effect of stirrer 4 with dry powder and mud uniform mixing by mechanical dehydration, thereby the water ratio of mud behind the adjusting mechanical dehydration, reach the requirement of sludge treatment, by the later mud of dry powder carrier modifying under the effect of minute hopper 5 and metering reamer 6, control the finished product work output of mud and enter drying sludge module exsiccant sludge quantity, the sludge quantity that enters irradiation modules is controlled by dry powder amount required in the modified module of dry powder, the hot blast that the material of drying sludge module has roasting kiln to provide is provided simultaneously, mud enters irradiation modules later on earlier through beater, under the effect of beater, break up fragmentation, enter revolving drier 7 then, the sludge-drying that moisture eliminator 7 comes out separates through cyclonic separator 8, the negative pressure of cyclonic separator is controlled by induced draft fan, the mud that contains in the tail gas after the separation adopts the bag-type dust of sack cleaner 9 to handle, whole technology compactness, operation continuously adopts three collection entrucking railway carriage or compartments can realize portable sludge treatment.
