Embodiment 1

[0025] In order to solve the problem of local abrasion of plates at the entrance of a wide-channel welded plate heat exchanger for solid-liquid two-phase flow after foreign matter and debris in the working medium block the flow channel between the plates, the present invention provides an anti-abrasion flow guiding device, which sequentially includes The inlet flange 2 connected with the system pipeline 1, the "sky round place" buffer distribution channel 3, the second rectangular flange 4, the "Z" type buffer distribution channel 5, the guide vane 6, and the plate with the heat exchanger 8 The first rectangular flange 7 to which the bundle 81 inlet is connected. The cross section of the "Z"-shaped buffer distribution channel 5 is rectangular. The above-mentioned components are connected by known welding. Wherein, the plate bundle is a professional term known to those of ordinary skill in the art, and will not be repeated here.

[0026] In addition, in the present invention,...

Embodiment 2

[0033] The difference between this embodiment 2 and the previous embodiment is that the anti-abrasion flow guiding device provided by the present invention is also provided with a filter device 9 at the entrance of the "Z"-shaped buffer distribution channel 5, and other parts are the same as the previous embodiment. . This embodiment 2 is mainly to solve the problem that foreign matter in the working medium blocks the flow channel.

[0034] The filter device 9 is composed of solid slats. The plate spacing of the solid slats is smaller than the plate spacing of the heat exchanger 8, which can effectively filter out large-sized foreign objects and sundries in the working fluid flow and prevent large particles from blocking the flow channel between the plates. , so as to prevent the abrasion of the plates at the inlet of the heat exchanger from being accelerated due to foreign matter blocking the flow channel between the plates.

[0035] In addition, in order to facilitate the r...

Abstract

The invention discloses an abrasion-resistant flow guide device which comprises a suction flange, a buffer channel and a first rectangular flange connected with the inlet of a heat exchanger, wherein the suction flange, the buffer channel and the first rectangular flange are sequentially connected with a system pipeline; the buffer channel comprises a Z-shaped buffer distribution channel; and at least a flow guide vane is arranged in the outlet of the Z-shaped buffer distribution channel. In the abrasion-resistant flow guide device disclosed by the invention, the buffer distribution channel is in a Z shape, thus the flowing angel change of the solid-liquid phase fluid in the Z-shaped buffer distribution channel is great and the buffer effect is good. Furthermore, the effective flow space in the Z-shaped buffer distribution channel is large and the flow velocity of the fluid when the flow is the same is low, thereby effectively reducing the partial abrasion of the plate beam of a heat exchanger by a solid-liquid phase flow.

Description

technical field [0001] The present invention relates to a guide device, in particular to an anti-abrasion guide device. Background technique [0002] In the industrial production of sandy alumina, the working medium of the intermediate sequence of the sodium aluminate solution and the agglomeration cooling process is a solid-liquid two-phase sodium aluminate solution with a solid content of alumina particles of 350-900 g / l. When the large-sized particles in the solution block the flow channel, it will accelerate the abrasion of the plates at the inlet of the heat exchanger. In addition, when the foreign matter and debris in the solution block the flow channel between the plates, the accelerated abrasion of the heat exchange plates is more obvious. [0003] CN1952586A patent discloses a solid-liquid two-phase flow welding type plate heat exchanger anti-abrasion guide device. The anti-abrasion diversion device consists of an inlet flange, a "Tian Yuan Di Di" type buffer dist...
