Technical field
The present invention relates to the heat exchange field, particularly a kind of absorption steam-type heat exchanger that is used for being recovered in the waste heat that utilizes waterglass production precipitated silica process solid water glass dissolving generation.
Background technology
Waterglass is the primary raw material that the production precipitated silica is commonly called as white carbon; Present one ton of white carbon need consume about 1.2 tons of waterglass; What consume in the general production process is that concentration is 25～35% liquid sodium silicate, and dissolving 1 ton of solid water glass, to consume 0.8～0.9 ton of pressure usually be 5～8 kilograms steam.
0.3～0.5 ton of water vapour of back discharge is accomplished in common 1 ton of waterglass dissolving, and has small amount of liquid waterglass and together discharge.
In the waterglass course of dissolution, steam directly discharges behind the entering surge tank, and 0.3～0.5 ton of steam of waterglass discharging per ton causes a large amount of steam wastings of resources; And give off small amount of liquid waterglass and cause environmental pollution.
China utility model patent CN202052475U discloses the vapor-recovery system in a kind of solid water glass course of dissolution; The steam of taking away when this utility model is discharged the liquid soluble glass in the gas-liquid separator reclaims, through the recovery of waste heat recovery groove and with its preheating heating cold water.But the waste heat recovery efficient of this utility model is not high, and energy utilization rate remains further to be improved.
Summary of the invention
It is high that technical problem to be solved by this invention provides a kind of waste heat recovery efficient, improves the absorption steam-type heat exchanger of energy utilization rate.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of absorption steam-type heat exchanger comprises ear seat 1, manhole 2, gland steam exhauster 3, advances cold water pipe 4, cylindrical shell 5, water-locator 6, hot-water outlet pipe 7, steam inlet pipe 8, and water-locator 6 comprises pipeline 10, distributor 9.In production precipitated silica process; Waterglass dissolving back gets into surge tank; The steam of surge tank discharging and small amount of liquid waterglass get into the heat exchanger bottom by steam inlet pipe 8, and the cold water pipe 4 usefulness pumps that advance at the heat exchanger top inject cold water simultaneously, through water-locator 6; Form water curtain; Thereby absorb the heat of surge tank discharge water steam, the hot water that contains small amount of liquid waterglass that obtains after the absorption goes out by hot-water line 7 to discharge entering waterglass dissolving tank, and a spot of low temperature clean water steam is discharged from the gland steam exhauster 3 at heat exchanger top.
Cold water can be selected the normal temperature running water for use.
Water-locator 6 has one deck at least, preferred five layers.
Water-locator 6 is set with each other by the pipeline of five kinds of different-diameters, and the ground floor pipeline 10 that advances cold water pipe 4 and water-locator 6 is nested together, and between adjacent two pipelines slit is arranged all, and cold water forms five layers of water curtain from flowing between the slit on the conical distributor 9.Steam penetrates five layers of water curtain from bottom to up, and heat is wherein absorbed by water, and water temperature raises, and the sensible heat of steam and latent heat major part are absorbed, thereby becomes clean Low Temperature Steam.
Preferably, distributor 6 is conical distributors.
Preferably, the diameter of the conical distributor of each layer is identical.
Preferably, the diameter of the conical distributor of each layer can also increase or reduce from top to bottom successively.
Preferably, each layer distributor 9 surfaces are provided with aperture, and it is more abundant that steam is contacted with cold water.
Preferably, the pipeline 10 upper end mouths of pipe of each layer water-locator 6 are processed the chamfering shape, so that regulate the discharge between the pipeline slit.
Preferably, the gap size between the pipeline of socket can be regulated each other, so that regulate the discharge between the pipeline slit.
The invention has the beneficial effects as follows that the water vapour of the discharging after solid water glass is dissolved behind the entering surge tank gets into the effect that this heat exchanger reaches the Steam Recovery utilization and absorbs liquid soluble glass, has effectively avoided the waste of steam and has reduced the pollution to environment.
