A color filter (200) comprises pixels (13) separated from each other by partitions (14) formed on a substrate (12) so as to have a plurality of color elements of ink. Dummy pixels (13′) are formed outside the area in which the pixels (13) are formed. The amount of ink applied to each of said pixels and the amount of ink applied to each of said dummy pixels are substantially equal. A protective film (21) covering said pixels (13) is formed so as to also cover said dummy pixels (13′).

The invention relates to a semielliptical falling film heat exchange tube with uniform flow guiding fins. The semielliptical falling film heat exchange tube comprises a first heat exchange unit, second heat exchange units and a third heat exchange unit which are vertically arranged from the top down; the first heat exchange unit comprises a first elliptical tube and a first fin; the first fin capable of uniformly guiding a flow is arranged at the exact lower part of the first elliptical tube; each second heat exchange unit comprises a second elliptical tube and a second fin; the second fins capable of uniformly guiding the flow are arranged at the exact upper parts and the exact lower parts of the second elliptical tubes correspondingly; the third heat exchange unit comprises a third elliptical tube and a third fin; the third fin capable of uniformly guiding the flow is arranged at the exact upper part of the third elliptical tube; the first fin of the first heat exchange unit is connected with the second fin at the exact upper part of the corresponding second heat exchange unit; and the third fin of the third heat exchange unit is connected with the second fin at the exact lower part of the corresponding second heat exchange unit. The flow guiding property of the semielliptical falling film heat exchange tube can be improved.

The invention relates to a biological drop filter and relative method for treating volatile organic waste gas, wherein it comprises that: feeding volatile organic waste gas into gas inlet tube (1) and main body (7) of reactor to be degraded and purified to be discharged from ventilate tube (9); the nutriment (11) enters into main body (7) via the nutriment distributor (18); the invention is characterized in that: the entrance of volatile organic waste gas is along the horizontal central line of main body 97); the nutriment (11) flows along the main body (7) from up to down, to form gas-liquid alternative contact in the main body (7). The invention can strengthen the biological degrade ability, with small area.

The invention discloses a composite-pipe type liquid distribution device. A feeding pipe is sleeved with a communication pipe, wherein two ends of the communication pipe are respectively connected with a connection flange plate and a plugging flange plate of the feeding pipe correspondingly; liquid distribution holes, which are distributed at equal intervals, are formed in the bottom of a plane of the communication pipe; liquid distribution pipes are respectively formed by butting a front-section liquid distribution pipe and a rear-section liquid distribution pipe which are arranged at the inner side and the outer side of the communication pipe; liquid outlet holes are formed in an upper half pipe body of the rear-section liquid distribution pipe; the rear-section liquid distribution pipe is sleeved with liquid distribution outer pipes and communicated with the communication pipe; liquid tanks and liquid distribution holes, which are distributed at equal intervals, are formed in the bottoms of pipe bodies of the liquid distribution outer pipes. The communication pipe and the liquid distribution outer pipes essentially form a secondary pipe type liquid distributor; kinetic energy of liquid in the distributor in any section is zero; the liquid in the distributor only has potential energy or static energy; liquid levels of the distribution outer pipes are kept on the same horizontal plane through the communication pipe, so that liquid volumes of the liquid flowing out of the distribution holes of the distribution outer pipes always remain equal. The composite-pipe type liquid distribution device has the characteristics of compact structure, uniformity in liquid distribution and great operating flexibility.
