Description
Technical field
The present invention relates to the triple effect devices of sun power drying sludge, be used for the drying treatment of water treatment field mud.
Background technology
Domestic sludge treatment often will be carried out landfill disposal to it behind the sludge press filtration at present, the moisture percentage in sewage sludge of preliminary treatment 〉=80%, therefore will take a large amount of land resources, the final unprocessed meeting of percolate of solid landfill imports underground drinking water, the drinking water hygiene that influence is human.Another kind of sludge treatment mode commonly used is to adopt mechanical drying, mainly contains types such as Flash Type, film type, spraying type, multiple-effect evaporation formula, all is to realize by thermal conduction, thermal convection and thermal radiation, needs to consume a large amount of energy.In order to ensure the security that anhydration system moves and not produce secondary pollution, need certain device guarantee, improved the cost of sludge treatment greatly.The one-time investment of sludge drying and working cost height are hung back a lot of sewage works, have seriously hindered the process that the small and medium cities sludge of sewage treatment plant is handled.At present a lot of middle or small sewage treatment " mud is completely for suffering from " have caused secondary pollution to environment.
Other treatment process is come sludge-drying as adopting electricity or oil, and is expensive big, running cost is high, also can produce certain pollution; Treating processes can produce a large amount of stenches, makes prestige and steps back, and has reduced the final treatment step of mud; Because electronically controlled development than later, has caused the level of automation of sludge treatment lower, must watchman's supervision on the scene carry out in the operational process.Receive in the sludge handling process that extraneous season and Changes in weather are bigger, be difficult for long-term stable operation.
Because domestic technique and energy development are later, use the chance of new forms of energy few, can consume a large amount of Nonrenewable resources in the former sludge handling process, the waste gas after the processing is not owing to have further to follow the tracks of to handle to cause all pollutions of atmospheric environment.
Summary of the invention
Goal of the invention: the present invention provides a kind of save energy, has reduced the triple effect devices of sun power drying sludge that pollute in order to solve the deficiencies in the prior art.
The technical solution used in the present invention: the triple effect devices of a kind of sun power drying sludge, comprise heat collector and kiln successively according to airintake direction, described kiln links to each other with heat collector by breather line, described kiln top is provided with hopper, the kiln side-lower is provided with discharge port, be provided with the mud transfer roller in the kiln, described breather line is provided with blow-off valve, described kiln below is provided with gas furnace, described mud transfer roller comprise from down under three layers of travelling belt and be contained in guide rail staggered up and down the adjacent two layers travelling belt, described heat collector comprises board-like heat collector, the blower fan that links to each other with described board-like heat collector, the heat pump that links to each other with board-like heat collector by breather line.
Adopt three layers of conveying belt, between the adjacent two layers conveying belt guide rail has been set, mud undulate on conveying belt is moved, prevented that mud from hardening, mud is stirred on conveying belt, guaranteed the thorough drying of inner mud, improved drying efficiency.
As preferably, described heat collector also comprises the heat pump that links to each other with described board-like heat collector, and described heat pump links to each other by breather line with described board-like heat collector.The sun power that utilizes natural cleaning is as the dry energy, green non-pollution, and cost is low, but along with changes of seasons, uses sun power can cause the temperature instability separately, connects heat pump and can keep the stable of heat supply on described board-like heat collector.
Described gas furnace side is provided with cold and hot water and imports and exports.Can get rid of a large amount of smelly air that contains in the drying sludge treating processes, below kiln, adorn gas furnace, can in combustion exhaust, realize repeating heat supply, realize the closed cycle of heat, save the energy.
Beneficial effect: the present invention has adopted the sludge drying mechanism of the lower auxilliary hot triple effects of solar heat pump of investment running cost, simple in structure, easy to maintenance, stable, dehydration and drying is effective, the level of automation height has reduced the mass consumption to the limited nature resource, has reduced in the sludge handling process second environmental pollution, reinforcement further reduces the unnecessary waste in soil the further processing of mud.
