Accompanying drawing explanation
Fig. 1 is the schematic diagram that a kind of dimethyl ether condensation water residual heat of the present invention reclaims heating installation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, the invention provides a kind of dimethyl ether condensation water residual heat and reclaim heating installation, it is characterized in that, described device comprises: methyl alcohol vaporizing recovery tower 1, gas-liquid separator 2, pump 4 and heating unit 5, described methyl alcohol vaporizing recovery tower 1 is connected to described gas-liquid separator 2, described gas-liquid separator 2 is provided with exhaust-valve 3, and described gas-liquid separator 2 is connected by pipeline with described heating unit 5, and described pump 4 is located on described pipeline; Described methyl alcohol vaporizing recovery tower 1, supplies steam condensate (SC) to described gas-liquid separator 2; Described steam condensate (SC) is separated into gas-phase product and liquid product by described gas-liquid separator 2; Described exhaust-valve 3, for discharging described gas-phase product; Described liquid product is delivered to described heating unit 5 by described pump 4, to realize heating.
Methyl alcohol vaporizing recovery tower 1 produces high-temperature steam condensed water, described high-temperature condensation water by Pipeline transport to described gas-liquid separator 2, described pipeline can also be provided with one or more pump, increase the efficiency of pumping, but also can cause the waste of the energy, high-temperature condensation water described in described gas-liquid separator separates, be separated and produce gas phase steam and high-temperature water, described steam is recycled by described heat exchanger 7, high-temperature condensation water to heating unit, is preferably provided with a pump by Pipeline transport on pipeline.
For realizing the efficiency utilization of water resource, preferably, described device also comprises: circulating water treatment pond, and described feeding unit is also communicated with described circulating water treatment pond.Active carbon is furnished with in described circulating water treatment pond.
Preferably, described gas-liquid separator is attached most importance to any one in strength liquid/gas separator, baffling gas-liquid separator, centrifugal force gas-liquid separator, silk screen gas-liquid separator, ultrafiltration gas-liquid separator and filler gas liquid/gas separator.The operation principle of gravity gas-liquid separator is, because gas is different from the density of liquid, liquid when flowing together with gas, liquid can be subject to the effect of gravity, produce a downward speed, and gas is still towards the flowing of original direction, that is liquid and gas separative tendency in gravitational field, downward liquid is attached to wall is gathered together and is discharged by delivery pipe.
The operation principle of baffling gas-liquid separator is, because gas is different from the density of liquid, when liquid flows together with gas and vapor permeation, if run into stop, gas is understood baffling and walks, and liquid is due to inertia, and continuing has a speed forward, liquid to be forward attached on only retaining wall face because the effect of gravity pools together downwards, is discharged by delivery pipe.
The operation principle of centrifugal force gas-liquid separator is, because gas is different from the density of liquid, when liquid flows together with gas and vapor permeation, the centrifugal force that liquid receives is greater than gas, so liquid has the tendency of centrifugation, liquid is attached to and is separated on wall because the effect of gravity pools together downwards, is discharged by delivery pipe.
The operation principle of filler gas liquid/gas separator is, because gas is different from the density of liquid, when liquid flows together with gas and vapor permeation, if run into stop, gas is understood baffling and walks, and liquid is due to inertia, continues trip one speed forward, liquid be forward attached to solely on gear filling surface because the effect of gravity pools together downwards, discharged by delivery pipe.Due to the classification of filler relatively common baffling, there is much bigger stop mobile phone wall area, and repeatedly baffling repeatedly, liquid is easy to wall, so its separative efficiency is improved.
High-temperature condensation water must have the efficiency utilization utilizing part could realize resource, urban heating system is provided with near plant area, high-temperature condensation water can enter into urban heating system, so both brought benefit for having contributed in city to company, because on-site is provided with Administrative Area, for improving the working environment of employee, can heat with high-temperature condensation water, preferably, described heating unit is domestic heating unit or industrial heating unit.
Utilize now high-temperature water to heat and mainly carry out heat exchange heating preferably by radiator, described domestic heating unit is radiator.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
