| titleOfInvention | Dichloromethane tail gas recovery system |
| abstract | The utility model provides a dichloromethane tail gas recovery system. In the system, the gas input condensing tank and the cooling liquid input condensing tank are opposite in position, gas-liquid two-phase countercurrent flow is realized, so that the gas in the condensing tank and the cooling liquid exchange heat more fully, the condensing effect is improved, the characteristic that the temperature required by vapor liquefaction is lower than the liquefaction temperature required by dichloromethane gas is utilized, the first-stage condensing tank is firstly used for cooling all vapor and partial dichloromethane, the water is completely introduced into the first-stage collecting tank, and then the dichloromethane gas which is not liquefied is gasified by the second-stage condensing tank with lower temperature, the ice blockage caused by the over-low temperature of the cooling liquid is avoided, the liquefaction efficiency of the dichloromethane gas is improved, and the extraction effect of the dichloromethane is extracted, set up the U type pipe in the transfer line simultaneously, play the liquid seal effect, avoid the dichloromethane gas direct transmission that does not liquefy yet to the one-level collecting vessel and volatilize, further improved the effect of extracting to dichloromethane. |
