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.

A diffuser assembly for diffusing a liquid in irrigation plants has a supply conduit includes a diffuser with a nozzle adapted to direct a jet of liquid along a longitudinal axis, at least one deflector facing the nozzle for radially spraying the jet outwards, and a connection device for ensuring fluid connection of the diffuser to the supply conduit of the plant. The diffuser is mounted onto the irrigation plant with the axis extending in a substantially vertical direction and with the nozzle facing up, and the deflector is configured to rotate about the longitudinal axis, thereby causing oscillations in the assembly. The connection device includes a tubular body with end joints that connect to the diffuse, and the supply conduit and the body is monolithic with the joints and is made of a thermoplastic elastomeric base material. Furthermore, the body has an outer surface with annular folds, which imparts elasticity and damp the oscillations induced by the deflector. A pivot or linear irrigation plant includes a plurality of those diffuser assemblies.

The invention proposes an industrial waste liquid treatment system and method based on carrier gas extraction low-temperature mass transfer. The system includes an absorber connected to a condenser connected to a waste liquid circulation pump connected to an absorber The liquid distributor of the resolver and the internal heater of the absorber; the resolver, which is connected to the evaporator, and the evaporator is connected to the clean water pump, and the clean water pump is connected to the liquid distributer of the resolver and the internal cooler of the resolver; the air outlet of the absorber is connected to the resolver The air inlet of the resolver, the air outlet of the resolver is connected to the air inlet of the absorber, and the air channel between the air outlet of the resolver and the air inlet of the absorber is provided with a circulating fan and an adsorber. The invention can use air as the mass transfer medium to realize the migration of water in the industrial waste liquid under the condition of relatively low temperature. A series of pretreatment processes such as precipitation, oil removal, and pH adjustment required for liquid disposal.

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.
