Abstract
The utility model relates to a tower plate for a bridge hole guide float valve, wherein the width of a front leg of the bridge hole guide float valve is smaller than the width of a back leg. The utility model is mainly formed by the combination of a flat leg bridge hole guide float valve and a high and low leg bridge hole guide float valve which have a proper combination rate and an arrangement form according to different liquid load on the tower plate in order to ensure that the liquid level gradation and liquid stagnation regions in the tower can be eliminated and each layer of tower plate stays in a best operation state, thereby, the integrative operation performance of the whole tower is increased.
Description
Technical field
The utility model relates to a kind of core component-valve plate of valve tower, relates in particular to a kind of guide float valve tray.
Background technology
Because valve tower has good operating characteristics, the gas-liquid mass transfer operations such as distillation, absorption, stripping in chemical industry and the petroleum industry have been widely used in.But industrial F1 type valve plate commonly used exists following significant disadvantage at present:
(1) gradient of liquid level is bigger on the column plate, makes gas skewness on liquid flow direction.Easily produce excessive leakage at the entrance point of column plate, perhaps, cause gas to spray at the port of export of column plate, the two all makes plate efficiency reduce.
(2) F1 type float valve is circular, and the gas that comes out from valve opening to all the winds blows out, and makes the liquid dispersion degree on the column plate bigger.Liquid dispersion on the column plate reduces plate efficiency.
(3) there is the liquid stagnation region at the arc position of column plate both sides.In stagnation region, liquid does not have main body and flows, and does not almost have to form by the gas phase of stagnation region to change, and this obviously reduces plate efficiency.
(4) in operation, F1 type float valve gyrates, and float valve and valve opening are worn easily, and float valve easily comes off.
In order to overcome the above-mentioned shortcoming of F1 type valve plate, many scientific workers have made various improvement to this, successively developed guide float valve tray (Chinese patent 91215110.2), with the trapezoidal float valve tray with guide effect (Chinese patent 92243924.9), their performance is better than F1 type valve plate, obtained significant effect in industrial application, still, the inventor finds that in long-term practice there is following shortcoming respectively in above-mentioned two kinds of valve platies:
(1) the rectangle valve plate is for big flow intensity, as the liquid flowing strength of column plate greater than 60M
3During/m.h,, be difficult to eliminate fully the gradient of liquid level on the column plate though the rectangle guide float valve tray can reduce gradient of liquid level.
(2) trapezoidal float valve tray (a kind of float valve is provided with the trapezoidal float valve of pilot hole), owing to not only promote liquid flow on the column plate from the pilot hole effluent air, and there is a component velocity at the liquid flow path direction from trapezoidal float valve both sides effluent air, also promote the liquid flow on the column plate to a certain extent, be that Trapezoidal Directed Valve Trays can be fluid on the column plate and flows bigger motive force is provided, it for big liquid flowing strength (as liquid flowing strength greater than 60M
3/ m.h), can eliminate the gradient of liquid level on the column plate fully, but it for less liquid flowing strength (as liquid flowing strength less than 20M
3/ m.h),, caused negative gradient of liquid level because trapezoidal guide float-valve is excessive to the motive force of liquid, influenced the operating characteristics of column plate.And owing to the motive force of trapezoidal guide float-valves all on the column plate to liquid flow is more or less the same, failing provides bigger motive force to the liquid flow of arch area on the column plate, so be difficult to eliminate the liquid stagnation region on the column plate.
In fact, the liquid phase of each layer column plate load is often different in the industrial same tower, even differs more than several times, the for example atmospheric tower of oil plant, butadiene extraction rectifying column etc., the liquid flowing strength of part column plate is less in its tower, and the liquid flowing strength of part column plate is bigger, and both often differ several times.Gradient of liquid level and liquid level stagnation region for good elimination column plate, independent rectangle guide float valve tray or independent trapezoidal float valve tray all are difficult to satisfy the different liquid flowing strength needs of industrial each layer column plate, need existing valve plate is further made improvements for this reason.
Summary of the invention
The utility model technical issues that need to address are a kind of bridge opening guide float valve trays of design, to overcome the above-mentioned defective that prior art exists.
Bridge opening guide float valve tray of the present utility model comprises column plate with valve opening and the bridge opening guide float-valve that is installed in the valve opening;

Be arranged on the angle on four angles of valve gap;
Be arranged on the bridge floor on the valve gap to upper process, on the slope of one side of the bridge floor of close preceding valve leg and bridge floor both sides are provided with pilot hole, the gas that pilot hole on the slope of bridge floor one side comes out is identical with liquid flow path direction on the column plate, and the gas that bridge floor both sides pilot hole comes out is vertical with liquid flow path direction on the column plate;
During installation, the bridge opening guide float-valve is placed in the valve opening, then the valve pin is pulled directly,, can be fixed on the column plate the bridge opening guide float-valve is floatable by cooperating of valve pin and valve limit.
The utility model has the advantages that very significant, gas flows out simultaneously from the both sides and the front portion of bridge opening guide float-valve, gas promotes flowing of liquid, and undirected back effluent air is so the liquid dispersion on the column plate is little, thereby the gradient of liquid level on the elimination column plate, back-mixing is little, has promptly improved plate efficiency, bridge opening guide float valve tray of the present utility model, the bridge opening guide float-valve does not have wearing and tearing, and tower plate structure is reliable.
