Abstract
The utility model relates to a drying device for drying sludge by utilizing flue gas. The utility model relates to environmentally friendly treatment equipment, in particular to a drying device for dynamically drying the wet sludge by utilizing the high-temperature (120 to 200 DEG C) flue gas. The drying device comprises a flue gas conveying pipeline and a sludge conveying device and is characterized in that the drying device comprises a barrel body, a hollow shaft, a conveying screw and a gas inlet passage communicated with the flue gas conveying pipeline. In order to solve the problems, the utility model provides the drying device for drying the sludge by utilizing the flue gas, which utilizes the flue gas to dry the wet sludge on line so as to greatly improve the treatment efficiency and reduce the environmental pollution.
Description
Technical field
The utility model relates to environmental protection treatment equipment, relates in particular to a kind of dynamically drying unit of dry wet mud of high temperature (120-200 ℃) flue gas that is used in.
Background technology
People have often ignored the processing to the mud that produces after the sewage disposal in sewage disposal, so the treatment facility of mud and technology relatively lag behind.Traditional method for sludge treatment one is a landfill, also will pay suitable expense in the landfill process, nor can guarantee not cause secondary pollution.The 2nd, this mode of roasting is science more not, and a large amount of heat energy of roasting needs, does not meet purpose of energy saving, causes secondary pollution again also for surrounding enviroment.Because the not science of sludge treatment, the incident that produces secondary pollution constantly takes place, and is perplexing enterprise and relevant departments always, obviously considers that from the angle of Sustainable development the reform of traditional treatment method is imperative.
In research and development, we find that there is the boiler of oneself in some unit, and the Sewage treatment systems of oneself is arranged.The hot waste gas that boiler is discharged, temperature reaches 140-180 ℃; Directly be disposed in the atmosphere, wasted a large amount of heat energy on the one hand, the particulate in the hot waste gas can produce bigger pollution to environment on the other hand.
And the sewage disposal meeting produces a lot of organic sludges, deals with, special trouble, and direct landfill, the land resources anxiety, it is available not have ground.Dry landfill again, drying process needs bigger cost.And we find after these organic sludge dryings, to have certain calorific value (1800-3500 kcal/kg), and have higher stickiness, can be used as coal-fired " additive ".
The utility model content
The utility model provides a kind of and has utilized the online dry wet mud of flue gas, and then improved processing efficiency greatly at above problem, reduces the drying unit that utilizes flue gas drying mud of environmental pollution.
The technical solution of the utility model is: comprise smoke conveying duct and mud e Foerderanlage, described drying unit comprises cylindrical shell, tubular shaft, defeated material spiral and is communicated with the uptake one of described smoke conveying duct;
One end of described cylindrical shell links to each other with the mud e Foerderanlage, and the top of the described cylindrical shell the other end is provided with the air outlet, the bottom is provided with mud mouth;
Described tubular shaft is movably arranged on the cylindrical shell middle part, with the cylindrical shell concentric; Described defeated material screw fixed is connected on the described tubular shaft; Described tubular shaft stretches out cylindrical shell towards the spindle nose that described cylindrical shell connects an end of mud e Foerderanlage, links to each other with uptake one by swivel joint; Described tubular shaft is provided with the pore of air flow line towards described defeated material helical surface.
Also be provided with the uptake two that is communicated with described smoke conveying duct, described uptake two is located at described cylindrical shell and connects an end of mud e Foerderanlage, stretches into cylindrical shell from the top with setovering a side, and the rotation direction inclination of pressing described defeated material spiral, rotatablely moving of described defeated material spiral produced the power-assisted effect.
The utility model as drying source, carries out dynamically dryly flue gas to the mud of high-moisture, make mud in moving process, efficiently volatilization moisture wherein.In this process, some particulates emissions in the hot waste gas, floating dust also can be by wet sludge absorption; Heat energy is approach exhaustion in drying process.Final clean gas of discharging near envrionment temperature.Mud is at the volley, and is progressively dry, after preventing that water content from reducing, and the mobile problem that reduces, the present invention is arranged to non-cylindrical with cylindrical shell, and the cross section, top is the shape in " tunnel ", has stayed the space that mud collides mutually in tube, blends like this.In addition, in the drying process, viscosity increases, be bonded on the defeated material spiral for preventing that mud is stained with, the present invention is arranged on high pressure exhanst gas outlet (some spileholes) on the tubular shaft, and like this, air-flow directly blows in helical surface on the one hand, can prevent the mud adhesion, on the other hand, wet mud there is drying effect " from inside to outside ", also has on the one hand, can effectively prevent the dry and hard one-tenth piece of mud, avoid " flowability " obstacle.At last, in order further to reduce energy consumption of the present invention, the hot waste gas import that will have high flow velocities faces toward the tangential of spiral, to the motion generation power-assisted effect of spiral.
