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 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 material provided by the invention distributes Despumation device to be arranged in the feed pipe in evaporator wall, described feed pipe has elbow in evaporimeter, described elbow is connected 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, show the spray apertures of bar shaped along circumferential parallel, wherein in every row's spray apertures, the level interval of adjacent spray apertures equates, between two adjacent row's spray apertures, mutually stagger, the diameter of described umbrella shape top cover is 2 ~ 3 times of diameter at described tubular sidewall top.
As preferably, for the liquid column and the medium contact face that make spray possess less angle, the rectangle that is shaped as 4mm*30mm of described spray apertures, the long limit of described rectangle is parallel with the axis of medium dispersal device.
As preferably, in order to adapt to the barometric gradient of liquid in dispersal device, make the liquid column spray of higher position more even, described tubular sidewall is round table-like, and the bus of described round platform and the angle of axle are 7 ~ 10 °.
As preferably, in order to make the liquid column of every row's spray apertures relative with the contact angle of medium fixing, the quantity of described every row's spray apertures reduces successively along feedstock direction.
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, and described feed pipe is horizontally disposed, and described elbow is 90 ° and is bent upwards.
As preferably, the height of described tubular sidewall is 580 ~ 660mm.
Beneficial effect: evaporimeter 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, adopt umbrella top cover to avoid material loss, not only avoid the foam that splashes and produce, and suppressed the loss of material to next effect heat exchanger, effectively reduce loss and the condensed water COD content of product.
