Description
Technical field
The present invention relates to the floating composite plate of a kind of Novel screen, belong to the gas-liquid mass transfer device field in the industrial process such as Chemical Engineering.
Background technology
The separation equipment of mixture occupies critical role in chemical industry, the quality of separation equipment performance, the height of technical merit will directly affect Yield and quality, the rate of recovery and the economic benefit etc. of product.Tower is one of nucleus equipment of oil-refining chemical production, also is widely used in the separating substances of the industries such as chemical fertilizer, pharmacy, environmental protection.Tower is that filler or column plate are divided into packed tower and plate column by tower internals, and column plate is the core of plate separation tower, is the place that gas-liquid contact carries out heat transmission and quality transmission.
Valve plate is to open valve opening at tower tray, the valve member that arrangement can fluctuate (except the standing valve).Because the gas flow area of valve plate can be regulated automatically with the gas load change, thereby can keep stable operation under wider gas load; Gas blows out with horizontal direction simultaneously, and gas-liquid contact time is long, and entrainment is few, has good operating flexibility and higher plate efficiency, has obtained using comparatively widely in industry.But valve plate complex structure, and sieve tray is the simplest column plate of structure, but the easy leakage of sieve plate, operating flexibility little, be difficult to operation, yet, the particular advantages of sieve plate---simple in structure, cheaply but attracting many researchers always.
For the shortcoming of common column plate in the past, in recent years, the composite plate technology has obtained very fast development.Each large tower manufacturer has developed large quantities of New Type of Trays both at home and abroad, and in order to transform original sieve-plate tower and valve tower, New Type of Tray is all to demonstrate wide application prospect on operating characteristics or improvement expenses.
Summary of the invention
The object of the present invention is to provide a kind of floating composite plate of sieve that strength promotes the hole that contains, this column plate combines the advantage of valve plate and sieve tray effectively, improves the percent opening of column plate, has increased operating flexibility and treating capacity; Simultaneously, the gas that sprays from strength promotion hole can promote liquid and flow forward, reduces liquid dispersion, reduces height of liquid layer, makes Gas distribution more even, has improved mass-transfer efficiency.
In order to realize this purpose, the present invention has adopted following technical scheme: column plate 1 is comprised of sieve aperture 3, float valve 2, strength promotion hole 4, seal pot 5, downspout 6, have float valve 2 gentle trying hard to recommend at sieve plate column plate 1 and move hole 4, have sieve aperture 3 gentle trying hard to recommend at float valve 2 and move hole 4, the structure that strength promotes hole 4 is fold-line-shaped.
The present invention compares with known technology, can comment as follows:
Have float valve 2 gentle trying hard to recommend at sieve plate column plate 1 and move hole 4, have sieve aperture 3 gentle trying hard to recommend at float valve 2 and move hole 4, the structure that strength promotes hole 4 is fold-line-shaped.The mentality of designing of this column plate, sieve aperture and float valve are combined at a column plate effectively, give full play to characteristics separately: when gas speed hour, float valve 2 is not opened, whole column plate 1 is exactly common sieve plate, and gas is passed through by the gap location that sieve aperture 3, strength promote 1 of hole 4, float valve 2 and column plate; When gas speed increases gradually, float valve 2 is opened gradually, and gas not only can be passed through by above-mentioned passage, can also pass through from float valve 2 holes.This characteristics have improved the percent opening of column plate, have increased treating capacity, can regulate flux by the perforate size of float valve, so that the operating flexibility of column plate is large, can satisfy actual needs.
Simultaneously, the strength of design promotes hole 4 on the sieve plate column plate 1, out gas from this hole, form the strength that promotes forward, to the power that promotes forward of one of flowing liquid forward on the column plate, regulate thus the situation of liquid flow on the column plate, comprise the liquid level drop of upstream and downstream of flow uniformity, the liquid flow of liquid.For so that gas provides regular aerodynamic force at column plate, on float valve 2 valve blocks, have corresponding strength and promote hole 4, the size in this hole, size, density and direction need to be offered according to the uniformity of liquid flow.The fold-line-shaped strength promotes the design in hole 4, flows forward so that the gas that sprays from strength promotion hole can promote liquid, reduces liquid dispersion, reduces height of liquid layer, makes Gas distribution more even, has improved mass-transfer efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1, a kind of floating composite plate of sieve that contains strength promotion hole is comprised of column plate 1, float valve 2, sieve aperture 3, strength promotion hole 4, seal pot 5, downspout 6.On sieve plate column plate 1, have the float valve hole of some, the arranging of float valve hole, according to the principle of arranging in sieve aperture 3 gaps, do not affect position and the quantity of leaving normal sieve aperture 3 on the column plate 1 as far as possible, float valve 2 distributes more at the both sides arcuate region, and middle less, liquid stream can be evenly distributed like this; For so that sieve aperture 3 on full column plate perforate as far as possible evenly, the appropriate location on the valve block of float valve 2 has the sieve aperture 3 of respective numbers, so that gas when rising from sieve aperture 3, is distributed uniformly.Simultaneously, strength on column plate 1 promotes the hole, out gas from this hole, form the strength that promotes forward, to the power that promotes forward of one of flowing liquid forward on the column plate, regulate thus the situation of liquid flow on the column plate, comprise the liquid level drop of upstream and downstream of flow uniformity, the liquid flow of liquid; For so that gas provides regular aerodynamic force at column plate, on float valve 2 valve blocks, have corresponding strength and promote hole 4, the size in this hole, size, density and direction need to be offered according to the uniformity of liquid flow; Strength promotes pore structure and is designed to fold-line-shaped (Fig. 4), is different from general ligulate or guiding shape, and this structure when gas passes through this passage, provides larger vertically upward thrust for the situation of large flux, promotes the unlatching of float valve.
Embodiment: design a kind of floating composite plate of sieve that strength promotes that contains, plate pressure drop has reduced by 50% than F1 type valve plate, has reduced by 10% than linde sieve tray; Operating flexibility has improved 10-20% than linde sieve tray, and separative efficiency has improved 10-20% than F1 type valve plate, has improved about 10% than linde sieve tray.
