Description
Technical field
The present invention relates to field of Environment Protection, and in particular to a kind of modified sludge treatment device.
Background technology
The water content of domestic sludge is universal very high, and existing sewage treatment process is using vapours in reactant
Sludge heated, play the effect of sludge dewatering, but be due to the pressure instability in reactant, vapours is in reactant
Distribution be not very uniform, most of vapours is gathered in the top half in reactant so that in reactant the latter half
Sludge dehydrating effect it is less desirable, in addition because the sludge inside sludge can not be contacted well in dehydration
To vapours, this make it that the whole dehydrating effect of sludge is uneven, and existing technology dewatered sludge moisture content typically exists
75%~85%, shape is bonded in colloid, secondary pollution is easily caused, and may also cause in transportation secondary pollution,
The requirement of environmental protection can not have been met, and sludge subsequent treatment means such as compost, burning, landfill etc. are required to moisture content 60%
Hereinafter, further reduction moisture percentage in sewage sludge is the important foundation of reducing sludge volume decrement, stabilisation and harmlessness disposing, additionally, due to
Content of organics is high among sludge, easily corrupt, and produces stench, so the stacking and discharge of sludge all can cause dirt to environment
A large amount of germs, parasitic ovum and the virus contained in dye, sludge, easily causes the propagation of infectious disease.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art there is provided a kind of dehydrating effect for sludge it is good and
The modified sludge treatment device of the harmful levels of pathogens in sludge can be removed.
Technical scheme：To achieve the above object, the present invention provides a kind of modified sludge treatment device, including be provided with into
Air interchanger, the air-breathing of the air interchanger are provided with outside the reactant of material mouth, steam inlet and discharging opening, the reactant
Pipe and escape pipe are connected with the top and bottom of reaction body sidewall respectively, are located in the reactant close to air intake duct and outlet
Be provided with the first longitudinal gauze layer at the mouth of pipe of pipe, the two ends of first gauze layer be separately fixed at reactant top and
The second horizontal gauze layer is additionally provided with bottom, the reactant, one end of second gauze layer is fixed on the first gauze
On layer, the other end extends towards outside reactant, is provided with the outer wall of the reactant for fixing the second gauze layer extension
Fixed block, be located above the second gauze layer in the reactant and be provided with agitator, the discharging opening by sludge pump with
The degerming room of high temperature is connected, and second gauze layer is located at the top at the mouth of pipe of escape pipe.
The present invention design principle be：When sludge carries out vapours dehydration in reactant, filled using ventilation
Put and the air containing more vapours of top in reactant is sucked into air intake duct, then reach bottom in reactant from escape pipe
Portion, forms the circulation that vapours is then return to reactant bottom from reactant bottom up liter, vapours is during rising
It is in contact with sludge so that overall dehydrating effect uniformity is good inside reactant；Sludge can be broken up, solve using agitator
The problem of sludge inside sludge can not touch vapours well；The setting of first gauze layer and the second gauze layer makes
Obtaining vapours can be touched by the sidepiece and bottom connection of the first gauze layer and the second gauze layer and sludge, expand contact surface
Product, improves dehydrating effect；The degerming room of high temperature is entered in the presence of sludge pump after other sludge dewatering, sludge is removed in high temperature
Harmful levels of pathogens, parasitic ovum and the virus in sludge can be effectively removed under the hot environment of bacterium room.
Further, the fixed block is provided with the groove matched with the extension of the second gauze layer, second yarn
The extension card of layer of cloth is fitted in groove and is fixedly connected by bayonet lock with fixed block.
Further, temperature inductor is provided with the reactant, the temperature inductor is connected to be located at reactant
Cooling gas air inlet is provided with temperature indicator on outer wall, the reactant, sludge dewatering has the temperature range specified,
Dehydrating effect can be influenceed if temperature exceedes specified range, temperature inductor can sense the real-time temperature detected in reactant
Spend and include temperature value on temperature indicator, operating personnel observe the real-time temperature in reactant by temperature indicator
Degree, once temperature exceedes the temperature range specified, then can open cooling gas air inlet and cooling air progress is passed through into reactant
Cooling.
Beneficial effect：The present invention compared with prior art, possesses following advantage：
1）Vapours in reactant can form shuttling movement from bottom to top, so that the sludge in reactant can
With touch vapours well, the top that existing vapours is largely gathered in reactant is solved, positioned at reactant
The problem of dehydrating effect of the sludge of the latter half is less desirable so that reactant for sludge dehydration uniformity very
Good, dehydrating effect is obviously improved；
2）Agitator can break up the sludge in reactant so that what sludge can be overall touches vapours, solves
Because the sludge inside sludge can not touch vapours well in dehydration so that the whole dehydrating effect of sludge
Uneven the problem of；
3）The setting of first gauze layer and the second gauze layer so that vapours can be in contact from sidepiece and bottom with sludge,
Vapours and the overall contact area of sludge are expanded, dewatering efficiency is improved, improves dehydrating effect；
4）The degerming room of high temperature is entered after sludge dewatering in the presence of sludge pump, sludge is under the hot environment of the degerming room of high temperature
Harmful levels of pathogens, parasitic ovum and the virus in sludge can be effectively removed, these harmful levels of pathogens, parasitic ovum and disease is solved
The problem of poison easily causes the propagation of infectious disease so that the discharge of final sludge is more environmentally-friendly and safe.
