Abstract
The present invention provides a feeding distributor with an anti-eddy flow baffle plate, which is composed of an inner sleeve barrel, a cover plate, a flow guide plate and an anti-eddy flow baffle plate, wherein the flow guide plate is arranged between a tower wall and the inner sleeve barrel, and a reinforcing rib of the flow guide plate is arranged on a face which is arranged on the flow guide plate and backs on to a feeding inlet. The anti-eddy flow baffle plate is arranged on the inner side of the inner sleeve barrel, a pull rid is arranged on the lateral side of the inner sleeve barrel, and the other end of the pull rid is fixed on the inner sleeve barrel. The cover plate presents an annular shape. In addition, the cover plate is positioned on the top of the inner sleeve barrel, one end of the cover plate is fixed on the tower wall, and the other end of the cover plate is fixed on the inner sleeve barrel. The baffle plate has the function of preventing rising airflow from rotating, reducing the entraining amount of liquid in the airflow, and simultaneously further distributing the rising airflow. The present invention has the advantages of eliminating airflow rotation which is caused by feeding of eddy flow and the entrainment of liquid drops, and avoiding the ununiformity of gas distribution, which is caused by the sudden change of circulating area and the difference of gas speed.
Description
Technical field
The present invention relates to the apparatus for feeding of tower gas phase and gas-liquid two-phase, more particularly relate to the tangential or two inlets feed distributor of a kind of list with swirl reducing baffle.
Background technology
Tower is a kind of gas-liquid, the liquid liquid contact mass transfer equipment of extensive use in oil and the chemical engineering industry.In recent ten years, along with the large scale development of packed tower and plate column, the even distribution of liquids and gases in tower is that the initial distribution of tower key issue, the especially inlet fluid of amplifying has significant impact to the separative efficiency of tower.At present, in industry, use more tower feed distributor and mostly be the even distribution that straight tube or other different feed stream guiding device by perforate are implemented in logistics in the tower, because the speed difference that the material perforate different from the position flowed out is so this kind distributor is difficult to reach the purpose of even distribution material.And the guiding device of other feed distributor exists gas to flow through pressure drop big, and there is air whirl in the distributor top and shortcomings such as skewness.Simultaneously gas when leaving distributor because the unexpected variation of circulation area must have the existence, gas pressure drop increase of eddy current etc.
Summary of the invention
The purpose of this invention is to provide a kind of feed distributor with swirl reducing baffle, be characterized in having the tangential admission distributor of inner sleeve, adding swirl reducing baffle, the effect of this baffle plate is to stop the air-flow rotation of rising, and minimizing is carried secretly liquid, and the while is the distribution ascending air further.
Purpose of the present invention reaches by following measure:
The feed distributor of band swirl reducing baffle of the present invention is made of inner sleeve, cover plate, deflector, swirl reducing baffle; Wherein: deflector is arranged between tower wall and the inner sleeve, and the deflector one side of charging aperture dorsad is provided with the deflector reinforcement; Swirl reducing baffle is arranged on the inboard of inner sleeve, and the side is provided with lacing wire, and the other end of lacing wire is fixed on the inner sleeve; Cover plate is an annular, is positioned at the top of inner sleeve, and an end is fixed on Ta Bishang, and the other end is fixed on the inner sleeve.
The feed distributor of band swirl reducing baffle of the present invention can be single tangential admission distributor or two inlets feed distributor, and the charging aperture of application can be single charging aperture, also can be two charging apertures.
Gas-liquid mixed material or be entrained with a large amount of drops and the gaseous phase materials of liquid foam enters feed distributor by feed pipe, and it is mobile along the annular space that forms by tower wall and inner sleeve, cover plate, between tower wall and inner sleeve, be provided with the different deflector of some height and positions, the material that enters distributor is led at the bottom of the tower uniformly, gas-liquid obtains separating in the space at the bottom of the tower, liquid flows to the tower still along the tower wall, and gas is then transferred upwards, and the drop in the gas is effectively separated.Because the inhomogeneities of the gas velocity at the bottom of the sudden change of circulation area and the guiding tower, the gas that returns up at the bottom of the tower must have eddy current and cyclone, causes the distribution of gas inequality, and carries the drop of some secretly.One group of swirl reducing baffle is set on the inwall of inner sleeve, has eliminated the eddy current and the cyclone of uprising gas, make uprising gas be evenly distributed, droplets entrained is fully separated.
The invention has the beneficial effects as follows, eliminated air-flow rotation that the swirling flow charging causes and, avoided the inhomogeneities of the distribution of gas that the difference owing to the sudden change gentle speed of circulation area causes the carrying secretly of drop.

The specific embodiment
The invention will be further described with concrete embodiment below in conjunction with accompanying drawing.
Embodiment 1:
The two inlets feed distributor of band swirl reducing baffle of the present invention, basic structure comprise inner sleeve, cover plate, deflector 4, deflector reinforcement, swirl reducing baffle, lacing wire.Cover plate and tower wall form the annular space of a top seal, bottom-open, deflector is arranged between tower wall and the inner sleeve, both sides are separately fixed on tower wall and the inner sleeve and are provided with the deflector reinforcement to improve intensity, and the deflector height gradually changes along the circular passage, both sides from charging aperture.Swirl reducing baffle is arranged on the inboard of inner sleeve, and the side is provided with lacing wire, and the other end of lacing wire is fixed on the inner sleeve.
Figure 3 shows that the basic structure pattern of inner sleeve and swirl reducing baffle, inner sleeve 3 height H are than the high 200～400mm of charging aperture 1 diameter, the width of inner sleeve 3 be its height 1/2 or less slightly, but be no less than 1/2 of charging aperture diameter.
The physical dimension of swirl reducing baffle 6 and inner sleeve 3 are closely related: the width L of swirl reducing baffle in the sleeve inboard is 1/3rd to 2/3rds of the high H of inner sleeve, be not less than 300mm, be generally 300～1000mm, the baffle plate bottom is concordant with inner sleeve, or a little more than inner sleeve, the base is straight flange or hypotenuse, and the hypotenuse angle is 30～45 degree, and the hypotenuse height is 1/3rd to 1/2nd of an inner sleeve height H.Swirl reducing baffle 6 tops exceed distributor cover plate 5 about 200～300mm, and top margin is from the horizontal by 0～30 ° angle, and extend to tower wall 8, are connected with tower wall 8 and distributor cover plate 5 to improve intensity.
