Expanding defoaming and dredging dry-type evaporator for water cooled centrifugal unit

Abstract

The invention discloses an expanding defoaming and dredging dry-type evaporator for a water cooled centrifuge unit. The dry-type evaporator comprises a grooved drum shell, an exhaust duct, air coolingboxes, a water cooled spray pipe, an aluminium plate heat exchange tank, a drainage pipeline and an outer propeller rotating disk; the exhaust duct and the drainage pipeline are welded with the upperand lower sides of the middle section of the grooved drum shell separately, and interpenetrate with each other; and the two air cooling boxes are provided, and installed at the right and left top corners of the water cooled spray pipe separately. According to the dry-type evaporator, through cooperative application between the outer propeller rotating disk and a fluidized bed plate, the outer propeller rotating disk is pushed by air pressure of a blower to rotate, so that a brush rotating frame is rotated on a film in an external expansion manner for brushing away steam foam; then, the foam is removed under the internal and external centrifugal air pressure of a concave corrugated groove and diaphragm blades; when the foam attaches to the fluidized bed plate, the foam is discharged with water flow, while air force is recoiled upwards for taking away hot air; and the effects of foam dredging and exhaust as well as up-and-down cyclone gas-liquid separation are achieved, and the functionof covering and removing the foam in the evaporator in a self-propelled pneumatic external expansion manner is achieved.

Description

technical field [0001] The invention relates to an expansion-type defoaming and dredging dry evaporator used for a water-cooled centrifugal unit, belonging to the field of water-cooled evaporation equipment. Background technique [0002] The application of the dry evaporator to the water-cooled centrifugal unit is to cooperate with the water-cooled heating to form evaporated water vapor to achieve the effect of heat dissipation and heat exchange, which can effectively promote the volatilization treatment effect after the heat is taken away during water-cooling, and prevent the deformation of the water-cooled unit due to thermal expansion and contraction In this case, the effective protection of water cooling and evaporation effect, but the evaporation of water vapor will form liquid foam, which needs to be cleared so as not to interfere with the operation of the equipment. The shortcomings of the current technology to be optimized are: [0003] The foam in the evaporator is ...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a dry evaporator for expansion type defoaming and dredging for water-cooled centrifugal units, to solve the problem that the foam in the evaporator is the embodiment of air contained in the liquid heat expansion water. The heated floating foam expands and accumulates in the evaporation vent, which will cause the pipeline to overflow. The overflow of foam and water stains will interfere with the exhaust efficiency. The problem of explosion hazard
