The invention relates to a plate type evaporator, which comprises a series of heat exchange plates stacked at intervals between the first heat exchange fins and the second heat exchange fins (2) to form an interlaced , isolated heat exchange channels; the first surface (6) of the first and second heat exchange plates has a heat exchange area (E); the first surface (6) is respectively provided with four corner holes corresponding to the cold / heat medium Liquid inlet channel or liquid outlet channel; at least one groove (3') is provided on the edge of the first liquid inlet hole (a) for cold medium inlet in the four corner holes, and the groove (3') starts from the first inlet The edge of the liquid hole (a) extends all the way to the heat exchange channel; the first surface (6) is centrosymmetric except for the four corner holes, but the arrangement of the center points of the four corner holes also satisfies centrosymmetry; the first and second heat exchange The plates are punched separately from the same substrate. Copper foil is applied on the first surface of each heat exchange plate, the heat exchange plates are stacked in sequence, and the copper foil is heated to melt to form a permanent bond between the first and second heat exchange plates.

The invention discloses a debris-flow drainage canal with energy dissipation and drainage functions and an application of the debris-flow drainage canal with energy dissipation and drainage functions. The drainage canal comprises a fully-lining drainage canal bottom plate and drainage canal side walls on two sides of the drainage canal bottom plate; the drainage canal bottom plate is in the shape of continuously-connected multiple-stage steps, the steps are provided with grooves; the width of the grooves on the top surfaces of the steps increases gradually along the flow direction of the debris flow, and the width of the grooves on the vertical surfaces of the steps decreases gradually; and the maximum width of the grooves on the top surfaces of the steps coincide with the maximum width B on the vertical surfaces of the steps. Compared wit the prior art, the step shape design is adopted to dissipate the energy of the debris flow all the way and the groove design is adopted to drain the debris flow, so the debris-flow drainage canal disclosed by the invention has high efficiency and good drainage capacity. By adjusting the height and the length of the steps and the size and the shape of grooves, the debris-flow drainagedrainage canal can be used for preventing the debris flow with any gradient and any nature.

The invention discloses a large air-cooling steam turbo generator stator capable of improving aeration-cooling effect and relates to a large air-cooling steam turbo generator stator. For reducing the maximum temperature rise of an air-cooling steam turbo generator stator bar, the invention adopts the technical points that: an orifice of inner bores of iron core sections which are positioned at the two ends of a stator main body is provided with a chamfer angle (alpha) of between 60 and 75 DEG, the orifice is an axial opening close to one side of an axial midperpendicular plane of the stator main body, and the depth (C) of the chamfer angle is 6 to 12mm. The heat radiating efficiency of a motor cooling system can be effectively improved due to the adoption of the generator stator structureprovided by the invention; and under the condition of a given inlet and fixed outlet pressure, when a chamber angle scheme is adopted, experiments prove that the maximum temperature is 3 DEG C lower than that of the conventional scheme after the temperature of the generator stator structure is solved, so the temperature of the hottest section of a motor is effectively reduced, and the whole temperature area of the motor is uniformized.

The invention relates to an inclined plate settling separating device which comprises a tower, an inlet for ammonium sulfate slurry carrying dust, a dust deposition area, an finished product area, a finished product outlet area and a dust deposition discharge port, wherein an inclined plate separating device in the tower comprises an upper upright type inclined plate separator and a lower inclined type inclined plate separator; the upper upright type inclined plate separator is composed of an upper inclined plate component, an inclined plate supporter and an upper support grid plate; and the lower inclined type inclined plate separator is composed of a lower inclined plate component, an inclined plate supporter and a lower support grid plate. By adopting the technical scheme of the invention, the problem that a finished product cannot be separated from dust effectively is solved; the flow field distribution and flow speed of the ammonium sulfate slurry carrying dust in the separating device are reasonable; the separating speed and the de-dusting efficiency are increased; the inclined plate settling separating device is simple in shape and can be conveniently processed and assembled; and aiming at the problem that dust is gathered in a desulfurizing tower and cannot be cleared off and the stable running effect is seriously influenced, the inclined plate settling separating device can be widely applied to a process of a wet flue gas desulfurization de-dusting system and can meet the requirement of 10m<3>-550m<3> ammonium sulfate slurry de-dusting treatment.

The invention relates to a slag sensible heat recycling system for an air-cooling dry slag machine. A horizontal segment, close to one side of a lifting segment, of the dry slag machine is provided with a shutter rotation opening-closing mechanism air inlet; the side, away from the lifting segment, of the air inlet is provided with an isolating device; the position, on the inner side of the top ofan outer shell, close to a joint of the dry slag machine and a boiler is provided with a temperature sensor; and the outer wall of the outer shell is provided with a controller, and the top of the dry-slag-machine lifting segment in the air-cooling dry slag machine is connected with a second air preheater and a first air preheater correspondingly through air pipes.
