Description
Technical field
The utility model belongs to garbage burning boiler technical field, is specially a kind of steam type airheater device of garbage burning boiler, can be widely used in multiple different types of garbage burning boiler.
Background technology
When self-contained thermoelectric plant, industrial production, need the steam using boiler to produce, the normally used fuel of boiler is fossil fuel, as coal, oil and gas etc.Fossil fuel are non-renewable primary energy, and because primary energy supply day is becoming tight, price constantly rises, and have become the significant problem of serious restriction national economy sustainable development.
In order to tackle the shortage of primary energy and develop the economy, improve the people's livelihood, the energy is had to the problem of more demands, except strengthening saving energy and reduce the cost, improve except the utilization rate of primary energy, also should actively make great efforts to seek new forms of energy, this have become the only way of various countries' energy strategy development.
Along with the fast development of economy and the raising of environmental protection consciousness, the problem being processed into current international community concern of a large amount of domestic waste is for the China of populous nation, particularly outstanding.The heat that house refuse burning produces is utilizable, if by consumer waste filling and embedding compost, not only waste resource, also pollutes the environment.Utilize house refuse to burn in the boiler, the steam of generation is used for generating and steam supply, has economize energy, reduces the social benefit of environmental pollution, also have good economic benefit.But if rubbish is not sufficiently burned, will produce a large amount of pernicious gas, processing cost will increase thereupon, even can serious environment pollution, and also boiler efficiency also will reduce greatly.
By low-calorie rubbish Thorough combustion, boiler wind pushing temperature must be improved, make it to reach more than 180 DEG C, if adopt general flue gas regenerative air heater, the problem of high temperature corrosion or cold end corrosion can be run into.In addition, when garbage burning boiler runs, with a large amount of ashes in flue gas, it can produce wearing and tearing to smoke air preheater pipe, reduction of service life.
Summary of the invention
In order to solve the problem, the utility model provides a kind of steam type airheater device of garbage burning boiler, and it can effectively avoid air preheater to corrode and wearing and tearing.
Its technical scheme is such: a kind of steam type airheater device of garbage burning boiler, it is characterized in that, it comprises shell and air preheater unit, described air preheater unit comprises pipeline section, described pipeline section is installed on described enclosure, and described pipeline section comprises upper collecting chamber, lower header, is connected between described upper collecting chamber and described lower header by vertical straight tube, described upper collecting chamber is communicated with import header, and described lower header is communicated with outlet header.
It is further characterized in that, described air preheater unit comprises multiple described pipeline section be arranged in juxtaposition, and each described pipeline section comprises multiple upper collecting chamber, the lower header of respective amount and multiple described vertical straight tube;
A described upper collecting chamber connects a corresponding described lower header by multiple described vertical straight tube and forms a tube panel, and adjacent tube panel is staggered in arrangement;
Described air preheater unit is installed at described shell two ends respectively;
The described housing at each described pipeline section two ends has access hole, described access hole is provided with access door;
Described outer side is provided with heat-insulation layer.
After adopting structure of the present utility model, heat source flows through in the pipe of pipeline section, and heated air, in pipe process, is avoided and smoke contacts completely, rational in infrastructure, can effectively avoid air preheater to corrode and wearing and tearing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 be in Fig. 1 A-A to sectional view.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of steam type airheater device of garbage burning boiler, it comprises shell 8 and air preheater unit, air preheater unit comprises multiple pipeline section 1 be arranged in juxtaposition, be specially three to four, it is inner that pipeline section 1 is installed on shell 8, each pipeline section comprises multiple upper collecting chamber 3, the lower header 4 of respective amount and multiple vertical straight tube 5, connected by vertical straight tube 5 between upper collecting chamber 3 and lower header 4, upper collecting chamber 3 is specially with the quantity of lower header 4 and is also three to four, multiple upper collecting chamber 3 is communicated with an import header 6, multiple lower header 4 is communicated with an outlet header 7, thermal source here can be steam, water etc., from import header 6, outlet header 7 passes in and out the thermal source of air preheater unit, can divide and converge to each upper collecting chamber 3 and lower header 4, save material, system is simple, import header 6 also can install exhaust, instrument etc., outlet header 7 also can be installed hydrophobic (blowdown) etc.
A upper collecting chamber 3 connects a corresponding lower header 4 by multiple vertical straight tube 5 and forms a tube panel, and adjacent tube panel is staggered in arrangement, and is convenient to making and installation, simple and reliable for structure, be beneficial to hydrophobic, the quantity of vertical straight tube can be selected as required, adapts to various capacity, the housing 8 at each pipeline section 1 two ends has access hole, access hole is provided with access door 2, access door is provided with side by side two handles, the object of such design is no matter the vertical straight tube 5 of which root needs maintenance or changes, attendant can carry out maintenance work by opening access door 2, if air preheater is directly by tens, 20 and even more tube panel composition, straight tube is had to need maintenance or change once medium position, due to factors such as heat transfer need, finite gap between straight tube, there is no space for maintenance at all, peripheral insulation can only be removed, backplate etc., cut off whole tube panel, reset again step by step after changing straight tube, at substantial manpower and materials, greatly increase the repair time, reduce the efficiency of power plant.
Air preheater unit is installed respectively in shell 8 two ends, and be conducive to reasonable distribution and the adjustment of thermal source, flexibility is large.
Shell 8 is backplates that steel plate and shaped steel are made, and main rising supports and sealing function, supports the weight such as pipeline section on the one hand, guarantees that air does not leak outside on the one hand; Outer side is provided with heat-insulation layer, and heat-insulation layer is made up of insulation material, for insulation of equipment, reduces heat losses.
