摘要： PURPOSE:To improve heat efficiency, by providing two heat exchangers on a drain discharge line, and providing a surface condenser and a mixing condenser, for using both a row liq. and a drain as a cooling water for the condensers. CONSTITUTION:A raw liq. is guided through a line 8 to a heat exchanger 14 to exchanger heat with a drain, is then guided to heat transfer tubes 16 in a heat exchanger 3 where a part of the steam is condensed, guided through a line 17 to a heat exchanger 4 to exchange beat with the drain, and is passed through a preheater 10 to an evaporator 1 to be vacuum condensed. The condensate is removed through a line 11 and the steam is passed through a line 7 to a compressor 2 to be compressed and cycled and used as a heat source. The uncondensed steam is brought into direct contact with a drain introduced from a drain reservoir 18 through a pump 19, condensed and discharged out of the system.

摘要： PURPOSE:To prepare a remarkably efficient energy-saving apparatus by connecting a circulation steam turbine to a supply source of medium pressure steam and supplying the exhaust to the heating system of evaporator. CONSTITUTION:The evaporator 10 consists of an evaporating boiler 20 and a heating boiler 30 which is a heat exchanger. A charging tube for the original liquid A is connected to the circulating passage C. The medium pressure steam turbine 41 as a driving unit is mounted on the circulating pump 40. The medium pressure steam S is supplied into the turbine 4 which starts rotating and drives the connected pump 40. The turbine waste which drives the turbine 41 is led to the upper part 34 of heat exchanger 33 through the tube 42 and the drain heat-exchanged with circulation liquid is discharged from the lower part 35. The medium pressure steam which is the energy source of the evaporator is depressurized very reasonably, resulting in energy-saving.

摘要： PURPOSE:To separate and recover sulfuric acid and aluminum sulfate from acidic waste liquor contg. dissolved Al produced by electrolysis by evaporating the waste liquor to separate hydrochloric acid, separating sulfuric acid and solid matter with a centrifugal separator and repeatedly subjecting the solid matter to dissolution and crystallization. CONSTITUTION:Acidic waste liquor contg. dissolved Al produced by electrolysis is fed to an evaporator 1 to evaporate and separate easily volatilizable hydrochloric acid and this acid is concentrated with a concentrator 15 and recovered. The remaining slurry substance is fed to a centrifugal separator 2 to separate a filtrate 23 which is highly concd. sulfuric acid and solid matter 24. This solid matter 24 is fed to the 1st dissolution tank 4, where concd. sulfuric acid 27 produced in the next stage is added to the solid matter 24, heated to 80-100 deg.C and stirred to prepare a supersatd. soln. This soln. is sent to the 1st crystallization vessel 5 to crystallize aluminum sulfate and the deposited crystals are separated from the filtrate 27 which is high purity sulfuric acid with a centrifugal separator 6. The crystals are put in the 2nd dissolution tank 8 and pure water 29 is poured to dissolve the crystals. The resulting soln. is fed to the 2nd crystallization vessel 9 to crystallize high purity aluminum sulfate, which is then separated from high purity sulfuric acid with a centrifugal separator 10, dried with a dryer 12 and recovered.

摘要： PURPOSE: To make it possible to handle a highly viscous liquid efficiently by adopting a jacket structure its partition wall and introducing a heat transfer medium in the said jacket structure of the partition wall. CONSTITUTION: A fluid introduced in the agitation vessel 1 through a nozzle 7a is made to flow down an inner space portion 11 and to flow up an outer space portion 12 by a propeller 4. Therefore, when the propeller 4 is made to rotate, the fluid circulates by moving from the lower portion of the inner space portion 11 to the outer space portion 12 through the propeller 4, ascending there and then dropping from the top end of a partition wall 9 onto the fluid in the inner space portion 11. At that time, a heat transfer medium either for heating or for cooling is properly introduced into a jacket structure 6, 7 formed by a wall 2 of the vessel itself and the partition wall 9. By this means, it is possible to secure a large heat transfer area toward the fluid in the vessel 1 and, therefore, to effectively handle a highly viscous liquid having a low thermal conductivity.
