| Specific volume | 0.8-1.0g/cm 3 | Specific area | 3980m 2/ m 3 |
| Backwash intensity | 12-15L/S.m 3 | Forcing filter rate | 20-40m/h |
| Contain dirty ability | The 2-3 of quartz sand doubly | Normal rate filtering | Test result |
As shown in Figure 3, be the on-the-spot pictorial diagram of this module, in the present embodiment the thick composite module of 1000 * 1000 * 190mm, compare with traditional evaporation roof insulation construction technology, have the characteristics simply and easily of constructing.During construction, only need will prefabricated module be transported to roofing and carry out assembly unit and get final product.
As shown in Figure 4, be the constructional drawing of the biological ceramic particle of the utility model, material is simple, and is with low cost.
Shown in Fig. 5 and 6, be the test structure of present embodiment and the temperature effect figure of each module.In this test, chosen six groups of different module altogether, the thickness that its maximum difference is exactly the heat insulation filtration beds of biological ceramic particle is different, and its thickness is selected as shown in the table, and table 2 is heat insulation module thickness:
Through overtesting, it is as shown in table 3 to collect data.Table 3 is an evaporation mold deblocking temperature distribution characteristics parameter:
(1) average correlation coefficient of heat insulation module and outside air temperature is: R
2=0.5622, the linearly dependent coefficient that exposes roofing temperature and outside air temperature with the period is: R
2=0.9188, reflect that outside air temperature is remarkable to the influence of the heat insulation module surface temperature of exposed roofing Influence of Temperature comparison evaporation;
(2) exposed roofing temperature is the sclerosis roofing; Its evaporate heat insulation effect relatively a little less than; And evaporate the exist heatcooling effect of heat insulation module owing to the surface, and reduced the influence power of outside air temperature, cause its surface temperature and outside air temperature to demonstrate more weak correlation;
(3) the correlation difference of the surface temperature of outside air temperature and each heat insulation module reflects opposing or the reduction effect of surface evaporation cooling effect to the outside temperature influence to a certain extent;
(4) to a certain extent, outside air temperature will want big to the influence with heatcooling effect roofing to the influence of the heat-proof quality of sclerosis roofing.
The foregoing description is merely the preferred embodiment of the utility model, is not the practical range that is used for limiting the utility model.Be that all equalizations of being done according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
