An exhaust gas after-treatment mixing device comprises a casing, a mixing pipe located in the casing and a partition plate separating the casing into an upstream space and a downstream space. The mixing pipe comprises a first pipe portion located in the upstream space and a second pipe portion located in the downstream space. The first pipe portion is provided with at least two first openings located on two sides of the first pipe portion, respectively. A shielding plate shields an upstream portion of at least one of the first openings. The shielding plate is shaped and positioned within the casing to urge exhaust gas flowing through the upstream space away from the first end of the mixing pipe and around the shielding plate prior to entering the first openings.

The present invention discloses a method and device for quick segmentation of an optical coherence tomography image, a computing device, and a computer readable storage medium. The method includes: extracting a feature value related to a pixel in the optical coherence tomography image from the pixel to obtain a feature value representative of the pixel feature, the feature value including at least one of an intensity gradient value of the pixel, an intensity multi-scale mean value of the pixel, and an angular feature value extracted from the pixel; inputting the feature value into a Sparse Bayesian Classification model containing values related to image features corresponding to a border, to obtain a probability that the image feature belongs to features of various image region borders; and obtaining borders of various image regions contained in a predefined image region based on the probabilities obtained for various pixels in the predefined image region.

Method and device for quick segmentation of optical coherence tomography image

The present application discloses an exhaust gas after-treatment mixing device including a casing, a mixing pipe and a partition plate fixed on a periphery of the mixing pipe. The partition plate includes a first plate on one side of the mixing pipe, a second plate on the other side of the mixing pipe and a third plate connecting the first plate and the second plate. The mixing pipe includes a first pipe portion and a second pipe portion. The first pipe portion is provided with at least two first openings located on two sides thereof, respectively. The exhaust gas after-treatment mixing device includes a first shielding plate and a second shielding plate shielding front ends of the first openings, respectively, so that most of exhaust gas needs to flow bypass the first shielding plate and the second shielding plate before entering the first openings.

The present application discloses an exhaust after-treatment mixing device including a housing and a mixing assembly located within the housing. The mixing assembly includes a first space, a second space and a third space. A top portion of the first space and a top portion of the second space are both in communication with the third space. The mixing assembly is provided with a first raised portion protruding upwardly into the third space and a second raised portion located below the first raised portion. A fourth space is formed between the first raised portion and the second raised portion. As a result, the distance and time for urea evaporation are increased and the uniformity of gas flow mixing is also improved.

The present application discloses an exhaust gas after-treatment mixing device including a first plate, a second plate and a mixer. The mixer includes a first space, a second space and a third space located between the first space and the second space. Top portions of the first space and the second space are in communication with the third space. The mixer includes a first raised portion protruding into the third space and a second raised portion located below the first raised portion. A fourth space is formed between the first raised portion and the second raised portion. As a result, the distance and time of urea evaporation is increased and the mixing uniformity is improved. Besides, a package with the exhaust gas after-treatment mixing device is also provided.

Exhaust gas after-treatment mixing device and package therefor

An exhaust gas post-treatment apparatus comprises a first mixing chamber assembly and a second mixing chamber assembly. The first mixing chamber assembly comprises a first housing provided with a first mixing chamber, a gas inlet pipe, a first mixing pipe at least partially located in the first mixing chamber and a perforated pipe located in the first mixing pipe. The first mixing pipe includes a first pipe body located in the first mixing chamber and a second pipe body extending from the first mixing chamber, wherein a side wall of the first pipe body is provided with apertures and flow plates located in the first mixing chamber. In the axial direction of the perforated pipe, the perforated area of the perforated pipe fully covers the length of the flow plates. The second mixing chamber assembly includes a flow-guiding hood.
