摘要： PURPOSE:To improve the heat efficiency of the titled evaporator by supplying a part of evaporated steam of a self-stem mechanically compressing system evaporator to a finishing effect as the heating source and reusing the balance steam as the heating source of the evaporator. CONSTITUTION:A part of the evaporated steam of the final effect of the self- steam mechanically compressing system evaporator is supplied to the single- effect evaporator (a finishing effect) as the heating source and the balance steam is reused as the heating source of the self-steam mechanically compressing system evaporator. For example, two effects are used as the self-steam mechanically compressing system evaporator and a single-effect evaporator is used as the finishing effect. A part of the evaporated steam generated from the second effect 2 is supplied to the single-effect evaporator 4 as the heating source through a pipe 10, the balance steam is sucked and compressed by a mechanical compressor 3 through a pipe 11, and the pressurized and heated steam is supplied to the heating chamber of the first effect 1 through a pipe 12 as the heating source. Consequently, the heat efficiency is improved.

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 improve the heat efficiency in an evaporator by intensifying the discharge of gases by an evacuation device, extracting a mixture of heated steam and noncondensable gases and utilizing the heat energy for preheating a feed liq. CONSTITUTION:A raw liq. F is supplied to the top part of the heating can 2 of an evaporator 2 and concentrated. The gaseous ammonia which is generated from the raw liq. F during the concentration and disturbs the heat exchange is sucked by an evacuation device 5 and discharged from a pipeline G. A mixture contg. about 10% of heated steam V2 and ammonia is discharged by a vacuum pump VP. The discharged steam, etc., preheats the feed liq. in a heat exchanger 6 and the ammonia in the steam is sucked by the evacuation device 5, condensed in a condenser 52 and removed. The drain condensed in the heat exchanger 6 is passed through a heat exchanger 7 along with the drain from the heating can 2 and utilized for preheating the feed liq. with its residual heat.

摘要： PURPOSE:To obtain an evaporator capable of working with reduced consumption of heat energy reducing a load of a vacuum generating device by installing a heat exchanger to between an outlet of an absorber and a heating boiler to remove only excess heat. CONSTITUTION:Liquid A to be treated which is introduced into an evaporator 10 is heated in a heating boiler 12 by exchanging heat. Steam V1 evaporated under vacuum is sucked into an absorber 20, and the treated liquid is concentrated and discharged as recovered liquid P. On one hand, an absorbent is circulated in the absorber 20, which is diluted by absorbing the steam V1. H2SO4, NaOH, etc., having high boiling point elevation rate is used as the adsorbent. The liquid absorbent is heated by the heat of dilution and the heat of condensation due to the condensation of the steam, then transferred to a heating side of the heating boiler 12 to serve as the heat source for the evaporation of the liquid A to be treated. Thus, the evaporator 10 has high heat efficiency because an absorption type heat pump is formed where the heat of the steam generated by itself is fed to the heating boiler 12 as the heat source.

摘要： PURPOSE:To obtain the titled product having improved flexural and compression strength in a short period, by heating a molded article granular or powdery artificial graphite and a binder to a calcination temperature at an extremely high rate of rise in temperature, impregnating it with a thermosetting synthetic resin. CONSTITUTION:Granular and/or powderly artificial graphite is blended with a small amount of a binder like air tar pitch to give a raw material, which is kneaded and molded. Then, the molded article is heated at 10-20 deg.C/hr rate of rise in temperature especially in a range of 150-650 deg.C, at 30-60 deg.C/hr rate of rise in temperature at >=650 deg.C up to a given temperature, 1,100 deg.C and calcined. Then, the calcined molded article is impregnated with a thermosetting synthetic resin, and cured under heating. By this method, a product having lower thermal conductivity than one on the market, but usable as a heat transfer pipe or bell mouth plate, having much higher flexural and compression strength, is obtained.

摘要： PURPOSE:To reduce the discharge amount of a discharged aqueous MgSO4 solution, by holding the pH value of the recirculation solution containing an Mg(OH)2 absorbent of an absorbing tower to a low value and depositing, separating and recovering MgSO4 from a waste absorbing solution. CONSTITUTION:Exhaust gas is guided to an absorbing tower 1 and brought into contact with a recirculation solution of which the pH is adjusted to 4.0-6.5 by an Mg(OH)2 slurry to absorb and remove SO2. A part of the recirculation solution is guided to a neutralization/crystallization tank 2 and Mg(OH)2 is added to said tank 2 from a pipe 14 to convert Mg(HSO3)2 in the solution to MgSO3. The deposited MgSO3 is guided to a solid-luquid separator 3, and separated and recovered. The filtrate is guided to an oxidizing tower 4 through a filtrate tank 16 and MgSO3 in the solution is oxidized to MgSO4 by air to be discharge out of the system as an aqueous MgSO4 solution from a pipe 19.
