Abstract
The utility model discloses a device for ensuring and controlling condensed water to be drained. The device is provided with an inlet and an outlet, wherein the inlet is connected with an upper effect evaporator, the outlet is connected with a lower effect evaporator, the device is a U-shaped pipe, and the height of a rising section of the U-shaped pipe meets the conditions that the water column pressure generated by water in the height is greater than the pressure difference of evaporation in the upper effect evaporator and the lower effect evaporator. In the device, the length of the U-shaped condensed water pipe is reasonably designed by calculating the pressure difference between the upper and the lower effect evaporators so as to ensure the U-shaped condensed water pipe to be communicated with the upper and the lower effect evaporators, ensure the condensed water to be smoothly drained, achieve the effect of sealing the upper and the lower effect evaporators in a liquid way and prevent the blow-by. The device has simple structure and low cost.
Description
Technical field
The utility model relates to the device that a kind of condensed water is discharged, and specifically is the device that a kind of evaporate station guarantees and the control condensed water is discharged.
Background technology
When evaporate station evaporated medium, the heating steam condensation formed condensed water.Condensed water is in time discharged in the evaporimeter domestic demand, in order to avoid influence the evaporator evaporation area, reduces evaporate station output; In this simultaneously, the condensate line that is discharged into lower effective evaporator can not directly be communicated with the two-effect evaporation device, to prevent collaborating destruction evaporating pressure separately between evaporimeter.At present, the evaporate station condensing water conduit is realized above-mentioned functions by restricting orifice is set.This requires the designing and calculating of restricting orifice must be accurately and reliably: if the restricting orifice of design is less than normal, can causes condensed water to discharge and be obstructed, influence disengagement area; If the restricting orifice of design is bigger than normal, can cause between the two-effect evaporation device and may collaborate, destroy the evaporating pressure of evaporimeter, finally reduce the evaporate station evaporated water.And the variable of the calculating of restricting orifice institute foundation is more, thereby has improved design difficulty, influences design accuracy.
The utility model content
The utility model provides a kind of device that condensed water is discharged that guarantees and control for solving the technical problem that exists in the known technology, and this device can make the smooth and easy discharge of condensed water and can prevent the collaborating between evaporimeter that link to each other.
Summary of the invention
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of also device of control condensed water discharge that guarantees, this device is provided with import that is connected with single-effect evaporator in the evaporate station and the outlet that is connected with lower effective evaporator, this device is a U type pipe, and the ascent stage of described U type pipe is highly satisfied: this height water generates water column pressure greater than in the last single-effect evaporator with lower effective evaporator in evaporating pressure poor.
The bottom of described U type pipe is connected with blow-off pipe, on the described blow-off pipe blowoff valve is installed.
Advantage and the good effect that the utlity model has are: by calculating pressure reduction between the two-effect evaporation device, thereby design condensed water U type length of tube easily, make it can play the effect that the two-effect evaporation device guarantees the smooth and easy discharge of condensed water that is communicated with, can reach fluid-tight between the two-effect evaporation device again, prevent the effect of collaborating.And the utility model simplicity of design, simple in structure, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, go up single-effect evaporator, 2, U type pipe, 3, blowoff valve, 4, lower effective evaporator.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, when 1 pair of medium of last single-effect evaporator evaporated, heat was emitted in the heating steam in its heating clamber, and heating steam is condensed into condensed water, and condensed water flows into U type pipe 2, drains into lower effective evaporator 4 by U type pipe 2.When needs blowdown or maintenance outage, open blowoff valve 3, impurity in the condensing water conduit or unnecessary condensed water are discharged by the blow-off pipe that U type pipe 2 bottoms are provided with.
The length H of above-mentioned 2 ascent stages of U type pipe determines, is the core of this device.By to the determining of evaporating pressures in the upper and lower single-effect evaporator 1,4, calculate pressure differential, during design as long as the water column pressure of water generates that guarantees the H height greater than this pressure differential, thereby can guarantee can not collaborate between the two-effect evaporation device, keep evaporating pressure separately.Certainly the H value can not be infinitely great, also need consider easy for installation and saving material.
Because the evaporating pressure in the last single-effect evaporator 1 is than the evaporating pressure height in the lower effective evaporator 4, and when the evaporate station apparatus arrangement, last single-effect evaporator 1 condensation-water drain to the water column pressure of vertical height between lower effective evaporator 4 condensed water imports less than the pressure differential between this two-effect evaporation device, thereby the condensed water of going up in the single-effect evaporator 1 can flow in the lower effective evaporator 4 swimmingly; The length H of 2 ascent stages of U type pipe only considers that to the influence that condensed water is discharged its resistance of ducting gets final product, and by calculating, arranges that in evaporate station the resistance of ducting value of the maximum U type length of tube generation that allows is very little, so the H value is very little to the influence of the smooth and easy discharge of condensed water.
In sum, the utility model is by adopting U type pipe and passing through appropriate design U type length of tube, reliably, discharged the condensed water of last single-effect evaporator effectively, in time, and forming effective fluid-tight up and down between the two-effect evaporation device, prevented collaborating between evaporimeter, keep the evaporating pressure in each single-effect evaporator, guaranteed the stable of evaporate station operation.The utility model has been simplified the technological design and the calculating of evaporate station.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
