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.

摘要： PURPOSE:To efficiently remove filter cakes attached to a filter plate in a closed type filter by feeding gas in a direction of passage of liquid to be filtered or in a reverse direction at a temperature of 100-150 deg.C and passing it through filter plates. CONSTITUTION:Slurry 16 is fed into a vessel 1 from a liquid feed port 15 and gas for pressurization is fed into the vessel 1 from a pressurization gas feed port 17 to pressurize the interior of the vessel 1 thereby effecting filtration, while filtrate is discharged from a filtrate discharge port 18. Cakes which are separated from the slurry 16 and left in the vessel 1 are washed as required and dried. The cakes are then scraped down by a smoothening arm 4 and discharged to the outside through a discharge pipe 5 and a cake outlet port 7. In each of said filtration, washing processes, the smoothening arm 4, slurry arm 6, etc., perform predetermined actions in response to the signals from a control means. Since gas for pressurization of too high temperature causes thermal decomposition of filter cakes or degradation of filter plate, a temperature 100-150 deg.C is preferable.

摘要： PURPOSE:To hold the excellent heat transfer property, promote the heat transfer and the thermal efficiency of the heat transfer tube by forming the heat transfer tube into a liquid-tight tube the outer part of which is made of a heat curing resin and graphite, and holding at its inner part a porosity possessed by a graphite tube. CONSTITUTION:The tube wall of a tubular body 6 made of a porous graphite is divided into two, inner and outer, parts. The inner part 3 at least the inner wall surface of the tube, is held by a structure of porous graphite 2, and the outer part 4, at least the outer peripheral surface of the tube, is constituted of a tubular body 6 of a liquid-tight structure. That is, the heat transfer tube is a tubular body having a so-called dual layer structure. A layer 51 of a heat curing synthetic resin is applied to the outer peripheral surface of the graphite pipe 2 and thereafter dried and cured or application, drying and curing are repeated. Alternatively, a heat curing synthetic resin is applied to the outer peripheral surface of the tubular body 6 both ends of which are blocked, and thereafter an atmospheric pressure is applied thereto, and is impregnated in the front surface portion of the tube, and then a heat cured liquid-tight layer 52 is formed via drying means including heating. Accordingly, this tube can be used as a tube for transporting the fluid, and since it has its porous inner part 3, at least inner surface, it has an improved heat transfer function as a heat transfer tube by the promotion of nuclear boiling.

摘要： PURPOSE:To efficiently sterilize the waste liquid from media and various facilities and to decrease the breakdown of the device by successively providing a steam ejector having a steam supplying pipe and liquid to be treated supplying pipe, heating equipment, a holding tube, and cooling equipment. CONSTITUTION:A negative pressure is generated in the inlet on the liquid (to be treated) supply side of the steam ejector 1 and the waste liquid contg. a large amt. of microorganisms from a microorganism culture device is sucked from the liquid (to be treated) supplying pipe 3 when satd. steam is supplied from the steam supplying pipe 2 to the steam ejector 1. After the effluent of the steam ejector 1 is heated by the heating equipment 4 using the steam as a heat source, the effluent is stagnated for 20 seconds while the effluent is passed through the holding tube 5 and, thereafter, the effluent from the holding tube 5 is cooled with the cooling equipment 6 and is discharged to the outside of the system.

摘要： PURPOSE:To realize the reduction of the running cost and equipment expense required for adjusting temp. of a drying gas by making possible an effective use of the adiabatic compression heat of a circulating blower and eliminating the need to provide a gas cooler on the outlet side of the circulating blower. CONSTITUTION:A filtration dryer comprises a condenser 22 adapted to cool a drying gas discharged from a vessel 1 with refrigerant and condense the vapor of the solvent contained in the drying gas; a circulating blower 25 adapted to adiabatically compress the drying gas cooled by the condenser 22 and send the gas back into the vessel 1 to produce a circulation of the gas; a temp. detecting means 26 for detecting the temp. of the drying gas being supplied into the vessel 1; and a refrigerant control means 27 for adjusting the temp. and/or amount of the refrigerant being supplied to the condenser 22 according to the detected temp., the temp. of the drying gas discharged from the circulating blower 25 being adjusted to a predetermined value.
