Description

Sludge high-drying charing process disposal system

Technical field

The utility model relates to environmental technology field, is specifically related to a kind of sludge high-drying dehydrating and conditioning method.

Background technology

The treatment technology of current mud mainly contains several as follows: aerobic (anaerobism) compost, heating power anhydration and incineration, directly carbonize burning, press dewatering landfill, press dewatering burning etc., and the relative merits of these sludge disposal technologies are: the fertilizer that aerobic compost produces exists market-oriented difficulty; The running cost of heating power anhydration and incineration is higher (processing cost of the mud of water ratio about 80% is 200 ~ 300 yuan/ton); The consumption of direct charing combustion energy is large, cost high (processing cost of the mud of water ratio about 80% is 180 ~ 280 yuan/ton); Press dewatering landfill is interim treatment technology, easily causes secondary pollution to environment, and limits by landfill place, its running cost higher (processing cost of the mud of water ratio about 80% is 150 ~ 200 yuan/ton); When press dewatering burns, consider that solid matter in mud and glassware for drinking water have certain avidity, therefore in order to ensure dehydrating effect, sludge treatment factory first can add some amendments to destroy the avidity between mud, water before press dewatering in mud, after such press dewatering, the water ratio of mud generally can control about 60%, so can reduce burning energy consumption.Press dewatering burns can be divided into substantially mixes that coal burns, added garbage burns and cement is collaborative burns, and during actually operating, the concrete way choice that burns needs again to combine local condition, and namely these burning disposal way choice can be subject to region restriction.

In sum, existing sludge disposal technology or to there is transportation cost high, the technological deficiency that energy consumption is high, be exactly that application is subject to region restriction, also or to environment can cause secondary pollution, therefore, how reduce sludge treatment cost, realize the maximum using of resource, this is that environmental technology field personnel are devoted to one of important topic studied.

Summary of the invention

The purpose of this utility model is to provide that a kind of use cost is low, environmental pollution is little and can realizes the sludge high-drying charing process disposal system of resource recycling.

For achieving the above object, the technical solution adopted in the utility model is: a kind of sludge high-drying charing process disposal system, it is characterized in that: comprise conditioner, pressure filter and the carbonizing apparatus arranged successively, mud inlet, the mud mouth of pressure filter are connected with the discharge port of conditioner, the mud inlet end of carbonizing apparatus respectively.

The beneficial effect adopting technique scheme to produce is: mud is first carried out conditioning modification and filter-press dehydration, and then carry out charing process, so not only energy consumption is low, and the carbon content of the carbonization product obtained after charing is large, thermal value is high, therefore has good marketable value, moreover, adopt the pollution of integrated processing system disposing sludge to environment disclosed in the utility model little, transportation cost is low, effectively can improve the economic benefit of enterprise.

Accompanying drawing explanation

Fig. 1 is system construction drawing of the present utility model.

Embodiment

A kind of sludge high-drying charing process disposal system, as shown in Figure 1, it comprises conditioner 20, pressure filter 50 and the carbonizing apparatus 80 arranged successively, and mud inlet 51, the mud mouth 52 of pressure filter 50 are connected with the discharge port 22 of conditioner 20, the mud inlet end 811 of carbonizing apparatus 80 respectively.Compared with prior art, the utility model is that the mud first after conditioning modification and filter-press dehydration is carried out charing process, so not only energy consumption is low, can reduce charing processing cost, and the carbon content of the carbonization product obtained after charing is large, thermal value is high, therefore there is good marketable value, concrete, this carbonization product can enterprise to be used by oneself heat production, or is sold to heat power plant, building materials unit etc.In addition, adopt the pollution of integrated processing system disposing sludge to environment disclosed in the utility model little, transportation cost is also low, effectively can improve the economic benefit of enterprise.

As further preferred version: conditioner 20 and the connecting pipeline of pressure filter 50 are provided with storage tank 30 and fresh feed pump 40, import, the outlet of storage tank 30 are connected with the discharge port 22 of conditioner 20, the import of fresh feed pump 40 respectively, the outlet of fresh feed pump 40 is connected with the mud inlet 51 of pressure filter 50, concrete, as shown in Figure 1, described pressure filter 50 is provided with the inlet mouth 53 connecting compressed air source.The progress that the layout of storage tank 30 can be produced integration carries out rationalization arrangement, what guarantee was produced continues to carry out, in addition, adopt fresh feed pump 40 to pressure filter 50 convey materials, adopt pressurized air to squeeze the propulsion source of mud as pressure filter 50 simultaneously, can ensure that the hydraulic pressure in mud successfully goes out by pressure filter 50 like this, improve the working efficiency of pressure filter 50, concrete, pressure filter 50 can select steel band pressure filter, barrier film plate-and-frame filter press or Special high-voltage plate-and-frame filter press etc.

More specifically scheme is: pressure filter 50 and the connecting pipeline of carbonizing apparatus 80 are provided with storage hopper 60 and stirrer 70, import, the outlet of storage hopper 60 are connected with the mud mouth 52 of pressure filter 50, the import of stirrer 70 respectively, and the outlet of stirrer 70 is connected with the mud inlet end 811 of carbonizing apparatus 80.As shown in Figure 1, by storage hopper 60, the filter cake produced after sludge press filtration is sent into stirring in stirrer 70, mud cake can be smashed like this and break up, thus facilitate the charing process of follow-up dewatered sludge, preferably, described stirrer 70 is biaxial rneader, and that can improve mud cake like this breaks up effect.

Concrete, as shown in Figure 1, described carbonizing plant 80 comprises dryer 81, carbonizes secondary stove 82 and carbonize main stove 83, the import of dryer 81, outlet are connected with the outlet of stirrer 80, the import that carbonizes secondary stove 82 respectively, the import carbonizing main stove 83 connects the outlet of the secondary stove 82 of charing, and carbonization product collection device is led in the outlet carbonizing main stove 83.Dryer 81 pairs of dewatered sludges are adopted first to carry out pre-heating drying, so not only can reduce the water ratio of mud further, but also dewatered sludge can be made further to be dispersed, so that charing process, reduce the energy consumption of sludge carbonization, in addition, the secondary stove 82 of charing is first adopted to carry out preliminary charing, and then mud dropped in the main stove 83 of the higher charing of temperature fully carbonize, so not only easily control the furnace temperature of each body of heater, but also effectively can ensure the effect of sludge carbonization, make carbonization product have good marketable value.

During practical application, the heat that can directly adopt standard coal or the fuel combustion such as biomass or combustion gas to produce makes the sludge carbonization in the secondary stove 82 of charing and the main stove 83 of charing, in order to make full use of the energy, preferably, as shown in Figure 1, carbonize secondary stove 82 to be connected with the thermal source import 812 of dryer 81 respectively by pipeline with the heat smoke outlet of the main stove 83 of charing, like this by the high-temperature flue gas produced in the secondary stove of charing 82 and the main stove 83 of charing as thermal source to the in addition preheating of the mud in dryer 81, achieve the recycling of heat energy, reduce sludge treatment cost further.
