Abstract
The utility model discloses a self-overflow controllable dewatering device, which comprises a dewatering tank body. A feed port is arranged on the tank wall at the upper portion of the dewatering tank body, a discharge port is arranged at the bottom of the dewatering tank body, an air exhaust port is arranged at the top of the dewatering tank body, and the air exhaust port is connected with an induced air fan through an air tube. The self-overflow controllable dewatering device dewaters sludge according to the characteristic that temperature of sludge is high after thermal hydrolysis, thereby effectively reducing moisture content of sludge, effectively recycling energy and being good in treatment effect and low in energy consumption.
Description
Technical field
The utility model relates to a kind of dehydration equipment, particularly relates to the controlled dewatering unit of self-overflow type that is used for the sludge dewatering of urban wastewater treatment firm mud heat treatment process.
Background technology
The monotechnics of urban wastewater treatment firm sludge treatment has multiple, but not enough or improper part are all arranged.For this reason, a kind of thermal hydrolysis treatment process has been invented by our company.The related invention patent name is: a kind of mud tubular type thermal hydrolysis treatment process and device thereof, (application number: 201010247557.7) this patent also is in the substantive examination stage at present.
The temperature of charge of traditional dewatering unit opening for feed generally should not too high (being no more than 60 ℃); And the general temperature out of mud all higher (between 60-120 ℃) after the thermal hydrolysis processing; Should not directly get into dehydration equipment dewaters; Need temperature of charge to be reduced, dewater again through heat-exchange equipment.
The utility model content
The utility model technical problem to be solved is to provide a kind of self-overflow type controlled dewatering unit to the existing existing deficiency of dehydration equipment, the dehydration of the controlled dewatering unit of this self-overflow type can be used to have comparatively high temps (＞100 ℃) solidliquid mixture.
The utility model technical problem to be solved can realize through following technical scheme:
The controlled dewatering unit of self-overflow type; Comprise the water knockout tank body; The tank skin on said water knockout tank body top is provided with opening for feed, and the bottom of said water knockout tank body is provided with discharge port, it is characterized in that; Top at said water knockout tank body is provided with venting port, and said venting port connects an induced draft fan through airduct.
In a preferred embodiment of the utility model, said opening for feed extends into the intravital end of water knockout jar and is connected with atomizer.
In a preferred embodiment of the utility model; Be provided with cross frame cleaner and screw rod discharger in the bottom of said water knockout tank body; The top of said screw rod discharger is connected with said cross frame cleaner, and insert in the described discharge port bottom of screw rod discharger.
The utility model mainly utilizes induced draft fan, and the water knockout tank interior is bled, and makes the water knockout tank interior form negative pressure (negative 0.04-0.06MPa); After having the thermal material entering water knockout tank body of certain temperature; Influenced by negative pressure, can produce a large amount of secondary water vapors, the secondary water vapor is discharged through venting port; Thereby reduced material with moisture, reduced water ratio.Secondary water vapor through venting port is discharged also can be recycled, and has avoided the waste of energy, improves energy utilization rate.It mainly is to make to get into the intravital material of water knockout jar and be evenly distributed that the utility model adopts atomizer, and the surface-area increase of material through the atomizing back makes in the material more that moisture is prone to be converted into water vapor, has strengthened dehydrating effect.The utility model is provided with cross frame cleaner and screw rod discharger in water knockout tank body bottom, and the back material of avoiding dewatering stops up in the inner accumulation of device, influences device and normally moves.
The utility model is compared with existing dewatering unit, is applicable to that high-temperature material and dehydrating effect are controlled, and it can be through negative pressure intensity in the control dewatering unit; Regulate dehydrating effect; When negative pressure increased, the secondary steam amount of discharge also increased thereupon, and the material water ratio of discharge is reduced.Through changing atomizer and other measures control atomizing effect, also can regulate dehydrating effect to a certain extent.
The utility model is handled the higher characteristics of back mud temperature to thermal hydrolysis, and mud is carried out processed, has not only effectively reduced moisture percentage in sewage sludge, also energy is carried out efficient recovery, and treatment effect is good and energy consumption is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the controlled dewatering unit of the self-overflow type shown in the figure comprises water knockout tank body 7, and water knockout tank body 7 adopts cylindrical shell and upper and lower end socket to be welded.The tank skin on water knockout tank body 7 tops is provided with opening for feed 1, and the end that opening for feed 1 extends in the water knockout tank body 7 is connected with atomizer 2.Certainly opening for feed 1 can adopt feed-pipe to replace.Be provided with venting port 3 at the top of water knockout tank body 7, venting port 3 connects an induced draft fan (not shown) through airduct.
Be provided with discharge port 6 in the bottom of water knockout tank body 7; And cross frame cleaner 4 and screw rod discharger 5 be installed in the bottom of water knockout tank body 7; The top of screw rod discharger 5 is connected with cross frame cleaner 4, and insert in the discharge port 6 bottom of screw rod discharger 7.Cross frame cleaner 4 can move up and down at water knockout tank body 7.
The working process of the utility model is following:
Open induced draft fan, make the water knockout tank body 7 inner certain negative pressure (negative 0.04-0.06MPa) that form., under certain pressure 0.1MPa or atmospheric pressure state, get in the water knockout tank body 7 through opening for feed 1 and atomizer 2 through the material after the hydrothermal treatment consists, the moisture in the material produces water vapor under negative pressure state, discharge through venting port 3.Owing to action of gravity falls into the material of water knockout tank body 7 bottoms,, discharge water knockout tank bodies 7 through discharge port 6 through cross frame cleaner 4 and screw rod discharger 5.Screw rod discharger 5 drives cross frame cleaner 4 and moves down in discharging, and the cross frame cleaner 4 that moves down scrapes the material on water knockout tank body 7 inwalls, and water knockout tank body 7 inwalls are cleared up.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand.The utility model is not restricted to the described embodiments; The just explanation of describing in the foregoing description and the specification sheets; The principle of utility model; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various variations and improves, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
