A kind of structure of aluminium electrolysis shop factory building
Technical field
The utility model relates to a kind of structure of factory building, relates in particular to a kind of structure that helps the aluminium electrolysis shop of factory building natural ventilation.
Background technology
Aluminium electrolysis shop, specific heat load is about 200w/m
3Below in conjunction with accompanying drawing existing aluminium electrolysis shop is described, Fig. 1 is existing cell room natural ventilation synoptic diagram, and electrolyzer 4 shells and power bus surface temperature be up to more than 100 ℃, service platform 9 apart from the skin temperature in electrolyzer 4 upper surface 450mm zones about 350 ℃.Operator's workspace radiant heat is very big, and air themperature can reach 70 ℃, and it is healthy to have a strong impact on the workman, also will influence electrolyzer works better efficient.
Air intake district, bottom 6 and workshop side window 5 air intakes are adopted in the realization of existing cell room 1 natural ventilation usually, and the structural shape of skylight or roof natural ventilation air draft is adopted on top.Side window 5 air intakes in workshop are subjected to influenced by wind pressure comparatively obvious, can cause air turbulence in the workshop, and reasonably air current composition can't realize that the factory building effect of natural ventilation is bad, and ventilation can't satisfy the workshop temperature requirement, and workshop and equipment surface temperature are too high.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of structure of aluminium electrolysis shop factory building is provided, and the utility model has carried out reasonable configuration to the workshop mill construction, effectively regulates air current composition, to strengthen the effect of natural ventilation.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of structure of aluminium electrolysis shop factory building, it comprises electrolyzer, service platform, space between groove, it is characterized in that determining the height of rational service platform according to the electrolyzer of differing capacities, service platform is raised, make the bottom air intake district air intake of the major part of outside air from the service platform bottom, the major part of room air is passed through from space between electrolyzer, cool electrolysis cells, some outside air is by being arranged on the factory building side in addition, the above grid interior wall in service platform plane enters the service platform plane, warm air is discharged outside the workshop by the natural ventilator or the skylight at factory building top, forms the orderly air-flow of nature in the workshop.
The height that the aforesaid operations platform is raised can be consistent with the electrolyzer upper level, also can be lower than electrolyzer upper surface 0-0.5m.
The height of aforesaid operations platform is 2.65-4.0m; The vertical side band height of grid interior wall is than the high 4.0-5.0m of service platform.
In place, air intake district, the bottom of above-mentioned factory building workshop exterior wall side, be provided with flow apron.
Advantage of the present utility model and effect are:
Owing to adopted technique scheme, the utility model is under the constant situation of workshop overall dimensions, regulate air current composition effectively, most of outside air is passed through from space between groove 7, cool electrolysis cells 4, and there is certain outside air to enter people's service platform district more equably and improves work situation, strengthened effect of natural ventilation.The total heat exhaust of the natural ventilation of novel mill construction 2 has bigger increase than the total heat exhaust of existing cell room 1 natural ventilation; The natural ventilation of existing cell room 1 is subjected to side window 5 air intake influenced by wind pressure in workshop comparatively obvious, easily causes the indoor air flow chaotic, and the natural ventilation of novel mill construction 2 is only worked its indoor air flow steady ordered under hot pressing.

Fig. 2 is the utility model cell room natural ventilation synoptic diagram;
Fig. 3 is the utility model cell room operating surface synoptic diagram.
Wherein, 1. existing cell room structure, 2. novel cell room structure, 3. air draft, 4. electrolyzer, 5. workshop side window, 6. bottom air intake district, 7. space between groove, 8. grid interior wall, 9. service platform, 10. flow apron.
Embodiment
The concrete structure of novel mill construction 2 is as follows: the height of determining rational service platform 9 according to the electrolyzer 4 of differing capacities, the height of service platform 9 is raised, the height of service platform 9 can be consistent with the electrolyzer upper level, also can be lower than electrolyzer upper surface 0-0.5m.The major part of outside air enters from the air intake district, bottom 6 of the bottom setting of both sides, workshop service platform 9, in addition some outside air is by being arranged on factory building side, the vertical side interlayer of grid interior wall 8 more than service platform 9 planes along its air intake highly in a organized way, the major part of room air is passed through cool electrolysis cells 4 from space 7 between electrolyzer 4 grooves; Roof natural ventilation or arc, Polygons or traditional rectangular skylight are adopted in air draft 3.
Service platform 9 highly is 2.65-4.0m; Grid interior wall 8 vertical side band height are than service platform 9 high 4.0-5.0m, and the grid of glass reinforced plastic window shutter, glass-fiber reinforced plastic grille, checkers grid or other insulating material formation is adopted in grid interior wall 8 air ports; Flow apron 10 is established on the top in air intake district, bottom 6, and it is end distance grade 2.4-3.0m down, with 30~45 ° of grade angles.
