Abstract

A Tube-still heat exchanger, pertains to the heat exchanging equipment field, which is mainly used to solve the problem of low heat exchanging efficiency and poor hot-expansion & cold-shrinking proof property of tube-still. The device has the same components as ordinary tube-still heat exchanger: a shell (1), a tube-still (2), an end cover (3) , a parting board (4) and corresponding interfaces; is characterized in that radiation & guiding fins (5) are installed regularly on the external wall of the tube-still (2), and the parting boards (4) are installed intermittently on the internal wall of the shell (1). The figured pattern card 16 on one end of the tube-still (2) is of a floating type. A left and right sealed type structure which can shift and slide along with the hot-expansion and cold-shrinking of the tube-still (2) is installed between the shell (1). The radiator can provide such virtues as high heat exchanging effect which is beneficial for energy saving and production cost reduction. The tube-still has favorable hot-expansion and cold-shrinking proof property which is beneficial to stable production, adapts especially to heat exchange between the cold and hot gas mediums.

Description

A kind of tubular heat exchanger

Technical field

The utility model belongs to field of heat exchange equipment, relates to a kind of tubular heat exchanger.

Background technology

With regard to tubular heat exchanger, mostly be the heat exchange structure that has the smooth tubular type of two end sockets---be that each tubulation is the light pipe that regular run-in index is arranged, no any annex on its pipe outer wall, walk short circuit for avoiding between pipe medium, dividing plate generally all is housed, so that medium forms baffling between pipe, " S " type flows, to improve the heat exchange effect, and the card at tubulation two ends all is fixing dead, and its weak point is, because medium flows fast between pipe between pipe, the time of staying is short, contact less and the time weak point with the tubulation outer surface, thereby heat exchange efficiency is lower, when differing big because of high low temperature in addition, because of fixing dead card is unfavorable for that tubulation expands with heat and contract with cold, occur accident easily, and be difficult to maintenance, it is more outstanding particularly to walk when being thermal source between pipe problem with hot gas.

Summary of the invention

The technical problem that solves:

Change the smooth structure of tubulation outer wall in the tubular heat exchanger, and establish floating type card, can overcome the deficiencies in the prior art, help improving heat exchange efficiency, strengthen the performance of the bloated shrinkage of tubulation heat resistanceheat resistant, help energy savings and steady production.

The technical scheme that adopts:

A kind of tubular heat exchanger has the basic composition of tubular heat exchanger, and housing 1, tubulation 2, end socket 3, dividing plate 4 and corresponding interface is characterized in that: the fin 5 that the double guiding of heat radiation is housed of rule on the outer wall of tubulation 2.

Beneficial effect:

The heat exchange efficiency height helps energy-conservationly and reduce production costs, and the tubulation heat resistanceheat resistant shrinkage performance that expands is good, helps steady production, easily implements, and is particularly useful for carrying out between hot and cold gas medium heat exchange.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings;

Among the figure, 6 is the import of thermal source medium, and 7 is the thermal source media outlet, and the thermal source medium is walked in the pipe; 8 is the heated medium import, and 9 are the heated medium outlet, and heated medium is walked between pipe; 10 is the end socket 3 formed inner chambers that are positioned at an end of thermal source medium import 6; 11 is water leg, and 12,13 are respectively the import and export of water; 14 is sealing ring, and 15 is packing holder; Simultaneously the pipe in and pipe between medium be the following current exchange type.

As shown in Figure 1, 2, fin 5 angle [alpha] of arranging on the outer wall of each tubulation 2 and spacing L all equate.Fin 5 easily adopts circular ring type.

As shown in Figure 1, dividing plate 4 is that MEDIA FLOW with the medium spiral escalation between pipe is on the inwall that is contained in housing 1 of screw type and discontinuous.

Shown in Fig. 1,3, be positioned on the card 16 of an end of heated medium outlet 9 packing holder 15 is housed, and have supporting sealing ring 14 to be contained in this to go up between inwall with housing 1 and seal, tubulation 2 expands with heat and contract with cold and can drive card 16 and sealing ring 14 left and right sealed displacement slip on the inwall of housing 1.

As shown in Figure 1, the import and export 12 of band water and 13 water leg 11 are housed also on the outer wall of housing 1, are beneficial to heat recovery and utilization.

As shown in Figure 1, when the hot furnace gas with the discharging of the combustion chamber of combustion furnace is the thermal source medium, is positioned on the madial wall of end socket 3 formed inner chambers 10 of an end of thermal source medium import 6 fire-resistant concrete layer is housed, and also have cleaning on this end socket 3 and cover 17.

The hot furnace gas that the utility model is specially adapted to the combustion chamber discharging of biomass energy gasification furnace is the thermal source medium, is heated medium with the air, is used for drying after air is heated.
