Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is described in further detail.

As it is shown in figure 1, a kind of reactor gas-vapor mix device, including having internal channel 11 and outer tunnel 12 Exchanger 1, internal channel 11 and outer tunnel 12 completely cut off by tube wall, internal channel 11 have inlet 11a and Liquid outlet 11b, outer tunnel 12 has water inlet 12a and outlet 12b, and inlet 11a passes through an aerofluxus Pipe 2a is connected to above reactor 2, and exhaustor 2a separates the return pipe 1a of a connection outlet 12b, enters Mouth of a river 12a connects a catch basin 3 by a water inlet pipe 3a, and liquid outlet 11b connects a liquor separator 4.Reaction The Volatile Gas produced in still 2 is known from experience through exhaustor 2a, then enters exchanger 1 internal channel from inlet 11a 11, from catch basin 3 cooling water then from outer tunnel 12 through importing inlet 1a simultaneously, gas and cold But together by internal channel 11 after water mixing, finally flow to liquor separator 4 and carry out separatory.Cooling water is not only made For heat exchange low-temperature receiver, also exist as solvent.Volatilization gas potentially includes water-soluble component and water-insoluble Component, owing to it has higher temperature, mixes latter aspect with cooling water and heat exchange can be occurred to condense, On the other hand component can be separated because of the dissolubility difference to water.Owing to gas is fully contacted with water, Therefore heat exchange is relatively more abundant, and condensation is more thorough, saves the energy, it is to avoid gas is asked workshop disperse Topic.

As shown in Figure 1 to Figure 3, the intersection of return pipe 1a and exhaustor 2a is provided with a mixing chamber 5, mixing Room 5 has the mistress 51 of connection exhaustor 2a and has connection with the inner chamber 52 connecting return pipe 1a, mistress 51 The outlet 511 of inlet 1a, inner chamber 52 is positioned at mistress 51 and is provided with some jet pipes 521 side by side, The mouth of pipe export-oriented 511 of jet pipe 521.The mouth of pipe sectional area summation of jet pipe 521 is less than return pipe 1a Sectional area, so greatly speeding up when cooling water enters flow velocity after jet pipe 52 from return pipe 1a, according to Bernoulli principle, pressure at the mouth of pipe reduces, and the Volatile Gas produced in reactor 2 is known from experience and allowed its pressure Raising, therefore under the effect of pressure differential, volatilization gas is inhaled into mistress 71.Cooling water is through too much Can form jet after individual jet pipe 521, each jet is fully contacted with the gas of surrounding, so can accelerate Heat exchange, prevents aqueous vapor adverse current.

As it is shown in figure 1, water inlet pipe 3a is provided with a water pump 6.Water pump 6 makes cooling water draw water from catch basin 3 And enter exchanger 1.Cooling water after heat exchange be easier to occur cavitation phenomenons, water pump 6 be in this Position can reduce cavitation and damage the risk of water pump 6.

As shown in Figure 1 and Figure 4, liquor separator 4 side is provided with liquid level tube 41, and liquor separator 4 from top to bottom depends on Secondary upper outlet pipe 42a, middle outlet pipe 42b and the lower outlet 42c of being provided with, the upper outlet of liquid level tube 41 with in Outlet 42b enter liquor separator 4 position contour, lower outlet 42c connect liquor separator 4 bottom and Catch basin 3, lower outlet 42c is provided with a flow speed control valve 8a；Upper outlet pipe 42a and middle outlet pipe 42b converges Enter a recycling can 7；Middle outlet pipe 42b is provided with a shut-off valve 8b.Close shut-off valve 8b, through exchanger 1 The liquid flowed out can produce layering, wherein water layer under, oil reservoir is upper；Opened by regulation flow speed control valve 8a Degree makes water-oil interface can indicate in liquid level tube 41, can be from lower outlet after water enters liquor separator 4 42c is expelled back into catch basin 3, owing to oil reservoir floats over above water layer, so oil reservoir will not be from lower outlet 42c Leave liquor separator 4, and recycling can 7 can be entered from upper outlet pipe 42a overflow；When reactor 2 terminates work After work, first close flow speed control valve 8a, make water-oil interface be higher than liquid level tube 41 peak, close water immediately Pump 6, opens shut-off valve 8b and allows oil reservoir all flow into recycling can 7, finally open flow speed control valve 8a by liquor separator 4 Emptying.The most just can complete oil-water separation, carry out the process of volatile component.

Above-described is only embodiments more of the present utility model.Ordinary skill for this area For personnel, on the premise of creating design without departing from this utility model, it is also possible to make some deformation And improvement, these broadly fall into protection domain of the present utility model.
