Part of the body in order to spray liquid drop state entering jar, and separation efficiency is high, and the feed liquid is little to jar body impact dynamics, lengthens the practical life of flash tank, locate to be equipped with filter equipment at steam outlet, reduced the impurity in the steam, and eliminated the effect that steam blisters when the export, the face that spouts of shower nozzle is equipped with the buffering hole, has prolonged the life of shower nozzle, also improves separation efficiency to a certain extent, the utility model discloses simple structure, convenient operation, the cost is lower, and the practicality is stronger.
Description
Technical field
The utility model relates to chemical industry equipment, especially for the flash tank in dimethyl ether preparation process.
Background technology
Flash distillation is exactly that the saturation water of high pressure enters after in the container comparing low pressure because the unexpected reduction of pressure makes these saturation waters become saturated steam under the container pressure of a part and saturation water.The boiling point of material increases with external pressure and raises, and allows high pressure-temperature fluid through decompression, its boiling point is reduced, enters flash tank, and fluid seethes with excitement rapidly vaporization in flash tank, and carries out two-phase laminated flow.The effect of flash tank is to provide fluid and gasifies rapidly and the space of gas-liquid separation.The flash tank used for the preparation of dimethyl ether at present, liquid-inlet direction is and tangentially enters or pass through strengthening mass transfer structure, and radial direction adds liquid, cause the liquid that enters too many like this, in the process of flash distillation, the flash distillation degree of methyl alcohol can be subject to obvious impact, and flash efficiency is low.
Utility model content
Problem to be solved in the utility model, overcomes the prior art deficiency that flash efficiency is low in dimethyl ether preparation process, provides one to be used exclusively in dimethyl ether preparation process, the flash tank of separation of methanol.
The utility model is achieved through the following technical solutions for solving this technical problem: a kind of flash tank standby for dimethyl ether, comprise tank body, tank body top is provided with steam (vapor) outlet, and tank body lower part is provided with discharging opening, also comprise filter and feed arrangement, described filter is positioned at tank interior, be fixed on tank body top, the bottom of steam (vapor) outlet, described feed arrangement is the material pipe extending to tank interior, and material pipe exit is provided with a shower nozzle.The raw material liquid preparing dimethyl ether enters in the tank body of flash tank by material pipe, is flowed out by shower nozzle.Because exit is provided with shower nozzle, raw material liquid is that the droplet-like of spraying enters in flash tank, be evenly distributed because drop sprays, so methyl alcohol can be separated from steam inlet rapidly in flash tank in boiling separation, the impact dynamics of the material liquid after separation to tank body also can reduce greatly.
In order to realize the utility model better, further, the described flash tank standby for dimethyl ether, described filter is the netted wire mattress of one deck.Isolated steam with certain material liquid impurity, therefore can be provided with filter course pad in the bottom of steam outlet, plays impurity screening, eliminate the functions such as foam, the netted silk pad of general selection, preferably netted wire mattress here, filter effect is better, and service life is longer.
In order to realize the utility model better, further, the described flash tank standby for dimethyl ether, the spray plane of described shower nozzle is also provided with cushion hole.Because material liquid outlet place is shower nozzle, be provided with cushion hole, reduce the pressure of feed liquid to shower nozzle, extend shower nozzle service life, and increase the input quantity of material liquid.
In order to realize the utility model better, further, the described flash tank standby for dimethyl ether, the spray plane of described shower nozzle is circular spray plane.Shower nozzle also can the spray plane of other shapes, and preferably circular spray plane, can more uniform spraying feed liquid.
In order to realize the utility model better, further, the described flash tank standby for dimethyl ether, described tank surface has one deck painting layer.Flash tank skin applies oil lacquer coat, can play protection flash tank tank body and not spoilt, and avoids the effect of getting rusty.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model Central Plains feed liquid enters tank body with flushing liquor drop-wise state, and separating methanol efficiency is high, and material liquid is little to tank body impact dynamics, extends the physical life of flash tank;
(2) be provided with filter at steam outlet in the utility model, reduce the impurity in steam, and eliminate the effect of steam foaming when exporting;
(3) in the utility model, the spray plane of shower nozzle is provided with cushion hole, extends the service life of shower nozzle, also improves separative efficiency to a certain extent;
(4) the utility model structure is simple, and easy to operate, cost is lower, and practicality is stronger.
