For addressing the above problem, inventor appears a kind of evaporimeter vapor-liquid separation Despumation device and obtain the authorization (ZL201320500760.X) in prerequisite, its structure as shown in Figure 1, comprise body feed tank 2 airtight on the housing 1 that is installed on vapour liquid separator, in the tangential direction of the housing 1 of the charging aperture 3 of body feed tank 2 in vapour liquid separator, body feed tank 2 is along the sidewall backspin in the shape of a spiral of housing 1, the discharging opening 4 of body feed tank 2 is concordant with the liquid level of housing 1 interior material, charging aperture 3 stretches out along the tangent line of housing 1, on the housing 1 of the discharging opening 4 of body feed tank 2 in charging aperture 2 opposites.Utilize in the material in the body feed tank directing material spiral fall-retarding incision housing of arc and mix with it again, avoid the foam that splashes and produce, but be limited to body feed tank outlet size, comparatively fast still can produce a small amount of liquid foam at present at flow velocity, become the bottleneck that promotes evaporation crystallization equipment disposal ability, be badly in need of a kind of Despumation device that liquid foam splashes that still can effectively suppress under high flow rate.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of evaporimeter separator material distribution Despumation device that can avoid liquid foam to splash under high flow rate.
Technical scheme: for solving the problems of the technologies described above, evaporimeter separator material provided by the invention distributes Despumation device to comprise the feed pipe being arranged on evaporimeter separator wall, described feed pipe has elbow in evaporimeter separator, described elbow is communicated with the medium dispersal device of vertically arranging, described medium dispersal device comprises the tubular sidewall and the umbrella shape top cover that are fixedly connected with, on described tubular sidewall, be arranged with circular spray apertures, described spray apertures is circumferentially arranged in parallel along tubular sidewall, and the quantity of every row's spray apertures reduces successively along feedstock direction.
As preferably, the suction-operated that the material of discharging for fear of top spray hole is subject to secondary steam pipe upwards loss enters next effect heat exchanger, and the diameter of described umbrella shape top cover is 1.5 ~ 2 times of diameter at described tubular sidewall top.
As preferably, in order to form evenly unrestrained liquid column, described tubular sidewall is round table-like, and the bus of described round platform and the angle of axle are 15 ~ 30 °.
As preferably, be ejected into the inwall of separator for fear of liquid column, described medium dispersal device is positioned on the center line of evaporimeter separator.
As preferably, for the ease of cutting stock and welding, described feed pipe is horizontally disposed, and described elbow is 90 ° and is bent upwards.
As preferably, the aperture of described spray apertures is 6 ~ 8mm, and the height of described tubular sidewall is 580 ~ 660mm as preferably, and for the ease of connecting charging aperture and pipeline, described charging aperture stretches out along the tangent line of housing.
Beneficial effect: evaporimeter separator material of the present invention distributes Despumation device to form shape spray by medium dispersal device directing material in vapour liquid separator, and optimal design the form of spray apertures and sidewall, in the situation that input mass flow is larger, still possesses higher foam removal efficiency, and avoided upwards loss of material by the structure of umbrella top cover, effectively reduce the loss of product.
