Detailed Description
In order to make the purpose and technical solution of the present invention clearer, the present invention is further described with reference to the accompanying drawings and embodiments:
as shown in fig. 1 to fig. 3, the single-effect concentrator and single-condensation combined recovery device comprises an evaporation chamber 1, a heater 2 and a condenser 3, wherein the right side of the evaporation chamber 1 is connected with the heater 2, and the left side of the evaporation chamber 1 is connected with the condenser 3: the upper part of the evaporation chamber 1 is provided with an air inlet ring 4 and an air exhaust ring 5; the gas extraction ring 5 is positioned above the gas inlet ring 4; the air inlet ring 4 is hollow and fixedly arranged around the inner wall of the evaporation chamber 1 and is provided with an air inlet; the air extracting ring 5 is hollow and fixedly arranged around the inner wall of the evaporation chamber 1 and is provided with an air outlet; the air inlet ring 4 is communicated with the air pumping ring 5 through a booster pump 6.
Preferably, the air inlet is formed by distributing a plurality of air inlets on the air inlet ring 4; the air outlet is formed by distributing a plurality of air exhaust holes on the air exhaust ring 5.
Preferably, the air inlet is an air inlet slit which is surrounded on the air inlet ring 4; the air outlet is an air exhaust slit which is surrounded on the air exhaust ring 5.
Preferably, the air inlet ring 4 and the air exhaust ring 5 are made of stainless steel.
The principle of the utility model is as follows: in the operation process of the single-effect concentrator single condensation combined recovery device, hot steam generated by a boiler (not shown in the figure) enters the shell pass of the heater 2 through a steam pipeline 21, feed liquid enters the tube pass of the heater 2, the liquid level of the feed liquid rises after being heated, the feed liquid is sprayed into the evaporation chamber 1 from the injection pipe 22 for steam-liquid separation, the feed liquid in the evaporation chamber 1 returns to the lower part of the heater 2 from the circulating pipe 11 to be heated again, the feed liquid is sprayed into the evaporation chamber 1 again after being heated to form circulation, the circulation is contracted to a certain degree, and the feed liquid is discharged from a discharge port after being qualified through sampling; steam above the evaporation chamber enters the shell pass of the tubular condenser 2 by vacuumizing, is condensed into liquid by cooling water in the tube pass, enters a condensed water collecting tank and is discharged by a condensed water pump.
When the bubbles generated in the process approach or reach the height of the air inlet ring 4, because the booster pump 6 works, the horizontal gas (the inside is not really vacuum, and the inside in normal production is generally 0.02-0.06MPa) of the air pumping ring 5 is pumped in and is sprayed out from the air inlet ring 4, so that the air inlet ring 4 has an instant pressure difference horizontally, the instant pressure difference exceeds the critical value of the surface tension of the bubbles, the bubbles are broken, the bubbles cannot exceed the horizontal line of the air inlet ring 4, and the bubbles cannot be pumped into a condenser in the process of vacuum pumping; since only the local pressure difference at the level of the air inlet ring 4 is changed, the overall pressure value of the evaporation chamber is not changed, and the influence on the vapor-liquid separation is slight.
