Abstract
The utility model discloses a sludge dryer with a waste gas treatment function and capable of preventing secondary pollution. The sludge dryer comprises a drying cylinder, a hot-blast stove, an induced draft fan, a high-temperature heat exchanger, a dehumidifier, a deduster, a solid-state adsorber, a liquid-state adsorber and a bioreactor, wherein a gas outlet end of the drying cylinder is sequentially connected with the induced draft fan, the dehumidifier, the deduster, the solid-state adsorber and the liquid-stage adsorber; a gas outlet of the induced draft fan is connected with a gas inlet of the dehumidifier; the high-temperature heat exchanger is arranged on a gas channel between the induced draft fan and the dehumidifier; a gas outlet of the high-temperature heat exchanger is connected with a gas inlet of the hot-blast stove; and a water outlet of the liquid-stage adsorber is connected with a water inlet of the bioreactor. According to the sludge dryer with a waste gas treatment function and capable of preventing secondary pollution, disclosed by the utility model, the induced draft fan leads the air of the dried sludge out of the drying cylinder, the waste gas is subjected to the treatment such as cooling, dehumidification, dedusting, solid-state adsorption, liquid-stage adsorption, and harmful substances in the waste gas are removed and discharged into the atmosphere to avoid secondary pollution.
Description
Technical field
The utility model relates to a kind of sludge dryer, relates in particular to a kind of sludge dryer with off gas treatment function that can prevent secondary pollution.
Background technology
Sludge dryer is applicable to the municipal sludge mummification, and the drying and other treatment of mud makes agricultural sludge, the use that acts as a fuel, burns and even become possibility for reducing the treatment processs such as landfill place.What the part sludge dryer adopted is that hotblast stove blows into dram by the air of high temperature by the dram feeding end, from the air outlet of dram discharge end, discharge again, present most of sludge dryer does not all have special emission-control equipment, just simply the waste gas dedusting deodorizing is just entered to atmosphere later, the objectionable impurities in waste gas is not removed, air has been caused to secondary pollution.
The utility model content
The purpose of this utility model provides a kind of sludge dryer with off gas treatment function that can prevent secondary pollution with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of sludge dryer with off gas treatment function that can prevent secondary pollution, comprise dram and hotblast stove, described sludge dryer also comprises induced draft fan, the high temperature heat exchanger, moisture trap, fly-ash separator, solid-state adsorber, liquid resorber and bio-reactor, the inlet mouth of described induced draft fan is connected with the air outlet of described dram, the air outlet of described induced draft fan is connected with the inlet mouth of described moisture trap, described high temperature heat exchanger is arranged on the air flue of described induced draft fan and described moisture trap, the air outlet of described high temperature heat exchanger and the inlet mouth of described hotblast stove are connected, the air outlet of described moisture trap is connected with the inlet mouth of described fly-ash separator, the air outlet of described fly-ash separator is connected with the inlet mouth of described solid-state adsorber, the air outlet of described solid-state adsorber is connected with the inlet mouth of described liquid resorber, the water outlet of described liquid resorber is connected with the water-in of described bio-reactor.
Particularly, place, the air outlet of described liquid resorber is provided with rain visor.
Particularly, the inlet mouth place of described high temperature heat exchanger is provided with the netted filtering plate.
The beneficial effects of the utility model are:
The utility model can prevent the sludge dryer with off gas treatment function of secondary pollution, induced draft fan will be dried air after mud from dram, drawing, waste gas is through processing such as cooling, dehumidifying, dedusting, solid-state absorption and liquid absorptions, after objectionable impurities in waste gas is removed, enter again atmosphere, avoided secondary pollution.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model can prevent the sludge dryer with off gas treatment function of secondary pollution.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model can prevent the sludge dryer with off gas treatment function of secondary pollution, comprise dram 1, hotblast stove 2, induced draft fan 11, high temperature heat exchanger 9, moisture trap 8, fly-ash separator 7, solid-state adsorber 6, liquid resorber 4 and bio-reactor 4, the inlet mouth of induced draft fan 11 is connected with the air outlet of dram 1, the air outlet of induced draft fan 11 is connected with the inlet mouth of moisture trap 8, high temperature heat exchanger 9 is arranged on the air flue of induced draft fan 11 and moisture trap 8, the inlet mouth of the air outlet of high temperature heat exchanger 9 and hotblast stove 2 is connected, the air outlet of moisture trap 8 is connected with the inlet mouth of fly-ash separator 7, the air outlet of fly-ash separator 7 is connected with the inlet mouth of solid-state adsorber 6, the air outlet of solid-state adsorber 6 is connected with the inlet mouth of liquid resorber 4, the water outlet of liquid resorber 4 is connected with the water-in of bio-reactor 4.
The place, air outlet of liquid resorber 4 is provided with rain visor 5.The inlet mouth place of high temperature heat exchanger 9 is provided with netted filtering plate 10.
The utility model can prevent that the principle of work of the sludge dryer with off gas treatment function of secondary pollution is as follows:
Induced draft fan 11 will be dried air after mud from dram 1, drawing, through high temperature heat exchanger 9, the part heat in waste gas is recycled to hotblast stove 2, can be to the waste gas processing of lowering the temperature in the time of energy-conservation, then waste gas is after the dehumidifying and dust removal process of moisture trap 8 and fly-ash separator 7, solid-state adsorber 6 will be delivered to liquid adsorber after the absorption of the part objectionable impurities in waste gas again, in liquid adsorber, waste gas is opposite with the flow direction of water, pollutent in waste gas is delivered to bio-reactor 4, pollutent is wherein further decomposed, and the waste gas after processing is disposed to atmosphere again.
