The device and the method are suitable for sludge drying and have the advantages of continuous operation, low labor intensity, high production efficiency, low heat dissipation and easiness in adjustment of granularity and water content of dried products.
Description
Technical field
The present invention relates to a kind of drying installation and the drying means of sludge disposal.
Background technology
Mud is the product after the sewage disposal, and since its water content height, complicated component, and contain more organic matter, and certain viscosity is arranged, at present, the method for disposal of mud mainly adopts landfill and compost.The landfill disposal options can take a large amount of land resourcess, and causes secondary pollution easily.Compost is according to the method for sterilization and slaking, and its fertilizer efficiency and security are different, and this disposal options can reach the purpose of resource utilization, but treating processes is longer, and can take a large amount of land resourcess equally, and disposal costs is also higher; In addition, contain the mud of objectionable constituent such as heavy metal, should not adopt this mode to dispose.
The greatly minimizing of dry back mud, innoxious and resource utilization.Dried mud can be used as building materials raw material, fuel etc.At present, the kind of drying installation is of all kinds, but because the viscosity of mud itself and its inherent characteristics, the drying installation that can directly apply to drying sludge is also few.For this reason, the present invention has studied a kind of sludge drying mechanism and method thereof.
Summary of the invention
Technical problem:The technical problem to be solved in the present invention provide a kind of be applicable to drying sludge, operation continuously, labour intensity is low, production efficiency is high, heat dissipation is low, the granularity of desciccate and water ratio are easy to regulate drying installation and drying means.
Technical scheme:For solving the problems of the technologies described above, spouted bed sludge drying mechanism with adjustable restrictor ring provided by the invention comprises the drying machine body, the top of drying machine body interior is provided with adjustable restrictor ring and the rod assembly that is used to regulate adjustable restrictor ring aperture that is connected with this adjustable restrictor ring, drying machine body top also is provided with the outlet that is used for dried dewatered sludge and thermal medium discharge drying machine body, drying machine body middle part is provided with the wet mud inlet that is used for the wet mud of input in the drying machine body, be installed in the drying machine body interior and be positioned at the whipping appts of its underpart, drying machine body bottom also is provided with the thermal medium import of input thermal medium in the drying machine body, the buncher that is connected with whipping appts.
The present invention also provides a kind of spouted bed drying method for sludge with adjustable restrictor ring, this method comprises the steps: that wet mud sends in the drying machine body from wet mud inlet, thermal medium is entered in the drying machine body by the thermal medium import, under the effect of whipping appts, wet mud fully contacts in the drying machine body with thermal medium, most of water rapid evaporation in the wet mud becomes dewatered sludge, and discharge the drying machine body from thermal medium outlet with the thermal medium after the cooling, adjustable restrictor ring and rod assembly have constituted adjustable throttling set, under the control of this adjustable throttling set, change the gas channel diameter of drying machine body, thereby regulate the drag characteristic of the intrinsic air velocity distribution of drying machine, thereby change mud granule in the intrinsic running orbit of drying machine and the residence time.
Beneficial effect:
1, drying machine body, the thermal medium import of drying machine bottom is tangential air intake, consequent swirling motion has reduced the possibility of the sticking wall of wet mud, has prolonged the residence time of thermal medium in drying machine.
2, whipping appts, the whipping appts of drying machine bottom can play crushing effect, makes wet mud can not gather group, thereby strengthened the caloic transmittance process, simultaneously, whipping appts has the cleaning effect to the drying machine inwall, stop the possibility of the sticking wall of mud, made drying process to carry out by continous-stable.
3, adjustable throttling set can be regulated the drag characteristic of air velocity distribution in the kiln, thereby stablize the control operating parameter effectively when initial physical parameters such as wet mud, drying medium change.
Description of drawings
Fig. 1 is the spouted bed sludge drier synoptic diagram with adjustable restrictor ring provided by the invention.
Wherein, 1 drying machine body; 2 wet mud inlets; 3 whipping apptss; 4 thermal mediums inlet; 5 bunchers; 6 restrictor rings; 7 rod assemblies; The outlet of 8 thermal mediums.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1, spouted bed sludge drying mechanism with adjustable restrictor ring provided by the invention, this device comprises drying machine body 1, the top of drying machine body 1 inside is provided with adjustable restrictor ring 6 and the rod assembly 7 that is used to regulate adjustable restrictor ring 6 apertures that is connected with this adjustable restrictor ring 6, and drying machine body 1 top also is provided with the outlet 8 that is used for dried dewatered sludge and thermal medium discharge drying machine body 1.
It is inner and be positioned at the whipping appts 3 of its underpart to be installed in drying machine body 1, and drying machine body bottom also is provided with the thermal medium import 4 of importing thermal medium to drying machine body 1 in, the buncher 5 that is connected with whipping appts 3.
Spouted bed drying method for sludge with adjustable restrictor ring provided by the invention, this method comprises the steps:
Wet mud is sent in the drying machine body 1 from wet mud inlet 2, thermal medium is entered in the drying machine body 1 by thermal medium import 4, under the effect of whipping appts 3, wet mud fully contacts in drying machine body 1 with thermal medium, most of water rapid evaporation in the wet mud becomes dewatered sludge, and discharges drying machine body 1 with the thermal medium after the cooling from thermal medium outlet 8.
Sometimes, because the physical parameter of wet mud such as tap density, water ratio etc. and drying medium parameter such as inlet temperature etc. are in operation and can change, make wet mud change even the instability that becomes in the intrinsic drying process of drying machine thereupon, it is frequent even do not reach production engineering specifications typically to show as the fluctuation of the granularity of desciccate and water ratio, to such an extent as to and may further cause the subsequent technique link to stop up the system that makes to be difficult to operation.And adjustable throttling set can be regulated the drag characteristic of kiln air velocity distribution by the throat diameter that changes the kiln gas channel, thereby changes running orbit and the residence time of mud granule in kiln, finally stable effectively control operating parameter.
