A solid particle redistribution device with adjustable distribution plate inclination angle

Abstract

The invention belongs to the technical field of fluidized bed heat exchange, and discloses a solid particle redistribution device capable of adjusting an inclination angle of a distribution plate. Thesolid particle redistribution device capable of adjusting the inclination angle of the distribution plate comprises the distribution plate arranged in a front seal head; the distribution plate is ofan arch-shaped piece structure composed of a chord edge and a arc edge corresponding to the chord edge and is provided with a plurality of rows of distribution holes uniformly distributed in concentric circles; a middle point of the arc edge of the distribution plate is connected to the bottoms of inlet connecting pipes through connecting hooks in a hooked mode; the chord edge of the distributionplate is connected to an adjusting shaft through connecting chains; the adjusting shaft is installed at the top of the front seal head through spiral fasteners; and when the adjusting shaft moves up and down, the distribution plate is driven by the connecting chains, so that the distribution plate rotates by taking a straight line passing through the middle point of the arc edge and being parallelto the chord edge of the distribution plate as an axis, and the inclination angle of the distribution plate is adjusted. According to the solid particle redistribution device capable of adjusting theinclination angle of the distribution plate, the inclination angle degree of the distribution plate can be adjusted on line according to different working conditions, the deposition condition of theparticles in the front seal head is improved, the non-uniform distribution degree of the particles in a tube bundle is reduced, the fluid turbulence is enhanced, and the heat transfer, antiscale and descaling are further enhanced.

Description

technical field [0001] The invention belongs to the technical field of fluidized bed heat exchange, and specifically relates to a solid particle redistribution device used in a front head. Background technique [0002] Scaling is a common problem in the industrial heat transfer process and often becomes a bottleneck restricting the production process. The generation of dirt increases heat transfer resistance, reduces heat transfer efficiency, increases energy consumption and environmental pollution, and even affects the normal operation of production in serious cases, causing huge economic losses and energy waste. At present, for the scaling problem of heat exchange equipment, some corresponding solutions have been proposed, such as increasing the flow rate, reverse circulation and using antiscalants. However, these methods cannot fundamentally solve the fouling problem, but also increase energy consumption, reduce heat transfer efficiency or aggravate environmental polluti...
