Description
Technical field
This utility model relates to a kind of rotary kiln heat collector, belongs to industrial afterheat recovery and utilizes technical field.
Background technology
Rotary kiln is a kind of visual plant being widely used in the industries such as metallurgy, chemical industry, building materials, and particularly in enterprises of producing stainless steel, rotary kiln determines the capital equipment of cement output and energy consumption especially. Stainless steel industry energy usage accounts for the 70% of building materials industry energy usage, this industry belongs to the enterprise of highly energy-consuming, high pollution, and its heat exchange efficiency only has 30% ~ 50%, there is the waste of the huge energy, wherein the substantial amounts of waste heat of rotary kiln surface outwards distributes throughout the year continuously, and the energy lost accounts for the 11.8% of total energy consumption. Rotary kiln barrel radiation make its surface temperature up to 200 DEG C ~ 400 DEG C, for preventing kiln body overheated, lower the temperature to kiln body frequently with big flow fan, not only caused high temperature and polluted but also waste the energy. So, fully, rationally kiln body surface residual heat resources, are effectively utilized, it is improve waste heat ladder producing level and energy utilization rate, effectively reduce the waste heat discharge thermal pollution to environment, the important measures of environmental and ecological environment, to building a resource-conserving society and friendly environment society, it is achieved the rotary kiln application energy-saving and emission-reduction of enterprise and regional sustainable development strategy target are extremely important.
At present, utilize the waste gas residual heat generation technology comparative maturity that rotary kiln end, kiln tail produce, the surface temperature of rotary kiln cylinder is also higher simultaneously, due to constantly rotating and temperature controlled requirement of rotary kiln, cause a series of difficult problems such as waste heat recovery sealing, therefore rotary kiln surface waste heat not yet effectively utilizes fully, and such Product recycling waste heat efficiency is low, not yet reaches desirable effect and carry out large-scale promotion application in engineering practice.
Utility model content
For the problems referred to above, this utility model provides a kind of rotary kiln heat collector, its object is to: improve industrial afterheat recovery utilization rate, solves the difficult problem that rotary kiln kiln body is overheated, has the advantages such as energy-saving and environmental protection.
Technical solution of the present utility model:
A kind of rotary kiln heat collector, including kiln body, it is characterized in that: be provided around heat collector in kiln body, described heat collector internal layer is the thermal-collecting tube according to ordered arrangement, described thermal-collecting tube is externally provided with reflecting plate, described heat collector outermost layer is color steel, is provided with heat-insulation layer between described color steel and reflecting plate, and described heat-insulation layer is that insulation fibre is cotton.
Described heat collector is the circular arc type matched with kiln body.
Described thermal-collecting tube is along kiln body axle longitudinal arrangement or transversely arranged.
It is provided with support, support and color steel bottom described heat collector and plays fixing and load-bearing effect.
The beneficial effects of the utility model:
The thermal-collecting tube that this utility model is arranged by vertical and horizontal is as the core parts of heat collector, reflecting plate can reduce systematic reflection rate, heat-preservation cotton can reduce system and external world heat exchange, it is possible to the heat reaching floor level dissipates well, and color steel and support play fixing and load-bearing effect, simultaneously, whole system adopts modularized design, it is possible to according to rotary kiln surface temperature conditions, install the waste-heat recoverer of varying number as required, convenient installation, does not affect rustless steel and produces.
Accompanying drawing explanation
Fig. 1: this utility model structural principle schematic diagram.
Wherein: 1 kiln body 2 thermal-collecting tube 3 reflecting plate 4 heat-insulation layer 5 color steel 6 support.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further:
As shown in Figure 1, a kind of rotary kiln heat collector, including kiln body 1, it is provided around heat collector in kiln body 1, described heat collector is the circular arc type matched with kiln body 1, described heat collector internal layer is the thermal-collecting tube 2 according to ordered arrangement, described thermal-collecting tube 2 is along kiln body 1 axle longitudinal arrangement or transversely arranged, described thermal-collecting tube 2 is externally provided with reflecting plate 3, described heat collector outermost layer is color steel 5, it is provided with heat-insulation layer 4 between described color steel 5 and reflecting plate 3, described heat-insulation layer 4 is that insulation fibre is cotton, support 6 it is provided with bottom described heat collector, support 6 and color steel 5 play fixing and load-bearing effect.
Heat collector is the design and installation thermal at cylinder of rotary kiln outer surface, for gathering heat recovery recycling, its operation principle is the dynamic temperature distribution for rotary kiln inside and surface, utilizes radiation and convective heat transfer mode, it is achieved the recovery of heat and utilization. Meanwhile, collector system also possesses temp regulating function, it is able to maintain that rotary kiln surface temperature remains within a metastable scope, it is ensured that produce the premise temperature conditions of high-quality, high-performance stainless steel, reduce again the energy consumption of producing stainless steel process.
Heat collector of the present utility model have the advantage that for: this system is modularized design, can according to rotary kiln surface temperature conditions, the thermal-collecting tube 2 of varying number is installed as required, this system is convenient simultaneously installs, can rotary kiln year fixing turn(a)round Fast Installation complete, do not affect stainless production.
To sum up, this utility model accomplishes the end in view.
