Detailed description of the invention
Fig. 1 is the structural schematic diagram of environmentally friendly sludge dry system provided by the invention.
Specific embodiment
The present invention provides a kind of environmentally friendly sludge dry system, to keep the purpose of the present invention, technical solution and effect more clear
Chu defines, and the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that tool described herein
Body embodiment only to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, a kind of environmentally friendly sludge dry system provided by the invention, including setting are indoor in the same drying
Blower 1, dehumidifying heating apparatus 2, drying sludge case 3, for purifying the biochemistry pool 4 of sewage, and for the sludge after drying
Carry out the sewage sludge harmlessness processing unit 5 of harmless treatment；The dehumidifying heating apparatus is for removing the wind that blower blows
Wet and heating, by the distinguished and admirable drying for carrying out sludge to drying sludge case for dehumidifying and heating；When wet heating apparatus is dehumidified
The sewage of generation flows to biochemistry pool and is purified.
The course of work of the system is as follows: in the same hothouse, blower can pass through to dehumidifying heating apparatus air-supply, wind
Dehumidifying heating apparatus forms dry-heat air and the condensed water (i.e. sewage) containing harmful substance, dry heat after being dehumidified and being heated
Wind, which enters in drying sludge case, is dried sludge, and condensed water is sent to biochemistry pool and is purified, the moisture evaporation in sludge
Dehumidifying heating apparatus is sent to by blower again into the air of hothouse, is so recycled.The sewage formed during this will not be direct
Discharge can be avoided secondary pollution, and the sludge dried can be sent to sewage sludge harmlessness processing unit and carry out subsequent processing, so that
Sludge reaches discharge standard.Sewage sludge harmlessness processing unit is the prior art, can be according to type (domestic sludge, industry of sludge
Sludge, agriculture sludge etc.) the corresponding sewage sludge harmlessness processing unit of selection.
Wherein, biochemistry pool and sewage sludge harmlessness processing unit are arranged outside hothouse, prevent sewage treatment and Treatment of Sludge
Process influences each other with drying sludge process.
Specifically, the dehumidifying heating apparatus 2 includes evaporator 2.1, the compressor for being in turn connected to form refrigeration cycle
2.2, air-cooled condenser 2.3, throttle valve 2.4；The wind that blower 1 blows successively flows to sludge after evaporator and air-cooled condenser
Drying box 3.Wind pass through evaporator 2.1 when can be cooled, the moisture in wind can evaporator surface condensation at condensed water, it is air-cooled
Condenser can be to the wind heat release after drying, to form dry-heat air.
Further, the dehumidifying heating apparatus 2 further includes the evaporative condenser 2.5 in parallel with air-cooled condenser 2.3,
Biochemistry pool 4 is flowed into after the condensation flow pervaporation formula condenser generated on evaporator.Since evaporator and condenser are using same
A dehumidifying air quantity, extra heat can only be discharged for condenser, waste of energy, and some refrigerant is guided into evaporation herein
Formula condenser carries out heat release, can be heated up using extra heat to condensed water, is given birth in life pond supplemented with condensed water
Change reaction needed for heat, heated it is not necessary that heater is in addition arranged (sewage is carried out in biochemistry pool biochemical reaction need reach
To certain temperature), it is seen then that extra heat is fully utilized, energy conservation and environmental protection.
