Abstract
The invention discloses an inner finned tube condenser which belongs to heat exchange equipment, and in particular relates to a condenser using an inner finned tube. The inner finned tube condenser comprises a vertical type shell, an upper tube box with a tail gas inlet, and a lower tube box with a condensation water outlet, wherein a cold water inlet and a hot water outlet are respectively located on two upper and lower sides of the shell, and the condenser is characterized in that an inner finned heat exchange tube is mounted between pipe sheets at both ends of the shell. An operation experiment of the heat exchanger shows that after the tail gas is subject to heat exchange, heat is very fully exchanged, the recovery effect, especially for organic solvent, is very good, and the recovery rate is increased by 10% compared with the heat exchanger currently in the market; at the same time the circulation interface of the heat exchanger is relatively large, and no resistance exists behind a vacuum pump; and the heat exchange is very thorough.
Description
Technical field
The invention belongs to heat-exchange apparatus, particularly use the condenser of internally finned tube.
Background technology
At present the most common condenser is generally tubular structure, and heat exchange area is little, and volume is big and heavy, and incoagulable gas forms barrier film equably attached on the tube wall, has hindered the heat exchange between the cold and hot material; In addition, tubular heat exchanger does not have the self compensation ability, changes under the condition of work in frequent heat, cold conditions, very easily causes the damage of parts.Moreover pipe can not disassembly, cleaning and fouling, and the coefficient of heat transfer descends year by year.
Summary of the invention
In order to overcome little, the bulky deficiency of existing tubular heat exchanger heat exchange area, the present invention provides a kind of inner fin tubular type condenser, and this inner fin tubular type condenser has enlarged heat exchange area, has improved heat exchange efficiency.
The technical solution adopted for the present invention to solve the technical problems is: a kind of inner fin tubular type condenser; Comprise upright shell, have the tail gas import upper tube box, have the lower tube box of condensate outlet; Cooling water inlet, hot water outlet lay respectively at goes up both sides under the housing, it is characterized in that: inner fin formula heat exchanger tube is housed between the tube sheet at housing two ends.
The structure of described inner fin formula heat exchanger tube does, the heat exchanger tube center is provided with sold inside the country, between the sold inside the country and heat exchanger tube inwall radial inner fin is housed.
The structure of described inner fin formula heat exchanger tube does; The heat exchanger tube center is provided with sold inside the country; Cambered top end and the sold inside the country tangent rounded arrayed of U-shaped fin are in heat exchanger tube, and two adjacent U-shaped fins interconnect near an end of heat exchanger tube inwall and are connected by the nickel-base seeping layer brazing layer with the heat exchanger tube inwall.
Sold inside the country two ends in the middle of the described heat exchanger tube are equipped with seal plug.
To be that stainless sheet steel is folding with sold inside the country tangent U-shaped fin form on described heat exchanger tube arc top.
Tail gas is got in the heat exchanger tube that inner fin is housed by the upper tube box interface and contacts with inner fin among the present invention, and hot water outlet is installed in the housing upside, and condensate outlet is positioned at the lower tube box interface and cooling water inlet is installed in the housing downside.With shell-and-tube cooler was different in the past, it is a heating agent by inlet pipe journey suitable for reading current downflow heat radiation in the inner fin passage, and end opening flows out condensate liquid, refrigerant by end opening advance shell side in shell with the heat exchange of pipe inner exhaust gas from outflow suitable for reading.Heat exchange element is the stainless steel thin-wall inner fin, and heat exchange area is 6 times of light pipes, and fin and tube wall adopt the nickel-base seeping layer soldering that very high thermal conductivity factor is arranged.After centrepin stops up, make the tail gas flow velocity accelerate augmentation of heat transfer; Refrigerant is sailed against the current by end opening inlet pipe journey and tail gas; The gap is about 1.5mm～2mm between the thin fin, thin fin thickness 0.15mm, and conduction heat and heat exchange tube wall are radial glide path; Flow velocity compares higher, makes the violent disturbance boiling of refrigerant strengthen heat exchange.Make heat exchanger that higher heat transfer coefficient is arranged for above-mentioned reasons, generally at 6000～8000w/m
2. ℃, solved the relatively poor problem of gas heat transfer, the heat exchange heat exchanger volume can be reduced.Tail gas and refrigerant heat exchange weight ratio differ greatly, and generally at 1: 30～1: 60, so steam flows in many Thin Stainless Steel fins that get into the heat exchanger tube radial arrangement, as having advanced the abundant heat radiation of capillary, cold medium flux flows in housing greatly.And, or not do not improved security at the pressure vessel category.
See tail gas through after the heat exchange from this heat exchanger running experiment, heat exchange is very abundant, and is especially very good to the Recovery of Organic Solvent effect, can improve 10% the rate of recovery than present heat exchanger on the market.The circulation interface of heat exchanger is bigger simultaneously, does not have resistance problem in the vavuum pump back.Heat exchange is very thorough.
