Description

A kind of closed condensate water recovery device
Technical field
The utility model belongs to industrial condensed water recovery technology field, is specifically related to a kind of closed condensate water recovery device that coordinates chemical catalyst synthesizer.
Background technology
As everyone knows, in industrial production, steam, as a kind of purposes energy very widely, is used to realize industrial product process procedure.And steam discharges the condensed water generating after partial heat energy often by line.This is that the i.e. efficiency of heating surface just must discharge condensed water low heat transfer efficiency as early as possible from steam because will improve the production efficiency of steam use equipment, and clearly this is a kind of waste.
Present most enterprises or has done boiler steam condensate-water recovery operation, instead of goes out in line condensed water as before.Because boiler steam condensate-water reclaim be improve boiler operating efficiency significantly, effective method, and the economic interests that produce are also maximum.Not only the waste heat of discharge has obtained effective utilization, has also saved on the other hand the chemicals of water resource and water treatment.The condensation water recovery system of an obvious successful operation, to saving energy and reduce the cost, increase economic efficiency important effect.
The effect that condensed water reclaims is to recycle heat and the demineralized water of condensed water, can adopt different process mode according to different situations.In general custom, there is dividing of open system and closed system, just carry out simply to introduce these two kinds of methods that condensed water reclaims below.
Open system, this system condensing water collection tank is open type, communicates with atmosphere, and while entering collecting box due to condensed water, pressure reduces suddenly, and water temperature, higher than boiling point corresponding to this pressure, produces a large amount of secondary flash steams, and residue condensate temperature is approximately 100 DEG C.In fact,, due to flash distillation heat radiation or sometimes in order to prevent that transportation water pump cavitation is blended into cold water, reclaim water temperature only 70 DEG C of left and right.In addition Recovery with Open-loop mode has air and enters condensed water recovery channel, easily causes corrosive pipeline.But open system device is simple, invest less.Compared with directly discharging with condensed water, still have certain energy-saving effect.
Closed system, in this system, condensed water collecting box is closed, and in system, condensed water pressure remains higher than atmospheric pressure, and make condensed water water temperature lower than the boiling point under this pressure, the heat energy of condensed water is fully used.And the original quality of the condensed water of closed system maintenance steam, during for boiler feedwater, can not increase dissolved oxygen content, also reduce boiler replenishing water amount, reduce the expense of water treatment.
Existing enclosed condensation water recovery system, applied environment is comparatively simple conventionally, and conventionally can there is not contaminated situation in condensed water, and therefore, its recovery is also comparatively easy.But, some chemical fields (as catalyst synthetic etc.), chemicals need to move in multiple operations; And in moving process, can pollute condensed water; If these contaminated condensed waters directly enter in boiler, can cause boiler to break down, reduce boiler service life.
In addition, due to distant between catalyst-assembly and condensate water recovery device, pipeline is longer, cause dilatation pressure drop at condensed water in high temperature in by pipe network course of conveying, existing closed condensate recovery device is prone to the not smooth situation of backwater, therefore, it cannot be applied to the chemical production field that pipeline is grown.
The 3rd, the rate of recovery of traditional enclosed condensation water recovery system and recovery heat are also lower, need to further improve.
