Description
Technical field
The present invention relates to a kind of heat-exchange system, relate to specifically the combined type heat-exchange system in the heat recovery system using of the industries such as a kind of petrochemical industry, thermoelectricity electric power, metallurgy, Thermal Power Engineering, belong to high temperature heat recovery system technical field.
Background technology
At present, conventionally use heat recovery system to recycle the heat energy of high-temperature medium in the industries such as petrochemical industry, thermoelectricity electric power, metallurgy, Thermal Power Engineering, the heat recovery system of this high-temperature medium generally adopts separate unit or many heat exchangers.Adopt Heat Exchanger to reclaim high temperature heat, have advantages of that high-temperature medium pipeline is few, occupation area of equipment is little, but have the shortcoming that step comprehensive utilization is poor, recuperation of heat usefulness is lower of heat energy; Adopt many heat exchangers to reclaim high temperature heat and have advantages of that recuperation of heat usefulness is higher, but between many heat exchangers high-temperature pipe length can cause the pressure loss of high-temperature medium larger, and adopt many heat exchangers, floor space is large, increases cost of investment.
For improving the utilization ratio of high-temperature medium recuperation of heat, high-temperature medium heat reclamation device is disclosed in some patent documents, if notification number is CN2557914Y, name is called in the Chinese utility model patent of " a kind of high-temp. sensible heat recovery assembling type heat-exchanger " and discloses a kind of unitized exchanger, it is low that this heat exchanger has high-temperature medium flow resistance, the advantage that occupation area of equipment is little, but because this heat exchanger expansion joint assembly overcomes the problem of thermal expansion, because expansion joint is a kind of consumable accessory, expansion joint is easy to occur accident after damaging, and the micro-fixed tube sheet shell and tube of this heat exchanger, under high-temperature condition, easily there is the problem of swelling cracking.And for example notification number is that CN201159608Y, name are called in the Chinese utility model patent of " unitized exchanger " and disclose a kind of Vertical Combination formula heat exchanger, this heat exchanger has advantages of that droop loss is little, good energy-conserving effect, floor space are little, but this equipment is that many heat exchangers are simply combined, and the heat exchanger of combination has also adopted fixed tube sheet tubular heat exchanger, also there is the easily safety problem of cracking.
Summary of the invention
The object of the present invention is to provide a kind of combined type heat-exchange system, to solve the technical problem that heat exchanger droop loss is large, floor space large, easily security incident appears in cracking in the high temperature heat recovery system of prior art.
The present invention adopts following technical scheme: a kind of combined type heat-exchange system, comprise that one end has high-temperature medium import, the other end has the housing that high-temperature medium exports, in described housing, be provided with heat-exchanging tube bundle, described housing is provided with outward with heat-exchanging tube bundle by the drum of pipeline communication, and described pipeline comprises and is communicated with at the down-comer between drum and heat-exchanging tube bundle import and is communicated with at the tedge between heat-exchanging tube bundle outlet and drum.

The drum that in described same housing, previous heat-exchanging tube bundle connects is communicated with the import of a rear heat-exchanging tube bundle.
The inwall of described housing is provided with heat-barrier material.
The present invention is arranged on heat-exchanging tube bundle in housing, heat-exchanging tube bundle is communicated with drum and is formed Natural Circulation by tedge and down-comer, in use, when high-temperature medium flows in housing, a part of heat of high-temperature medium is taken away by the medium in heat-exchanging tube bundle, make high-temperature medium temperature reduce, and due to the mobile distance of high-temperature medium and resistance little, its droop loss is also less; In addition, because heat-exchanging tube bundle is arranged in housing, heat-exchanging tube bundle can free wxpansion, has avoided the safety problem of heat-exchange system cracking.Simultaneously because heat-exchanging tube bundle is communicated with drum, medium under the effect of Natural Circulation in heat-exchanging tube bundle enters in drum, make the medium in drum heated, finally obtain the thermal medium of different temperatures, different conditions, thereby the heat energy of high-temperature medium is fully used.And due to the effect of drum, the medium in heat-exchanging tube bundle, in fluidized state, has heat-transfer film system large, save heat exchange area.Therefore, the shell side of combined type heat-exchange system of the present invention is short, high-temperature medium flow resistance and resistance is little, droop loss is little, be not prone to the safety problem of swelling cracking, and the heat energy of high-temperature medium can be fully utilized.
Further, two or more housings are set, high-temperature medium can flow in two or more housings, and the present invention can be reclaimed the heat energy of multi-series high-temperature medium.
Further, two or more heat-exchanging tube bundles are set in each housing, high temperature thermal medium, in the time that housing flows, by multiple heat-exchanging tube bundle transferring heats, further improves the recovery utilization rate of high-temperature medium heat energy.
Further, by the drum of two or more different potential temperatures is set, high-temperature medium medium, in the time that housing flows, is delivered to the heat of high-temperature medium in the drum of corresponding potential temperature by heat-exchanging tube bundle, thereby obtains the medium of different temperatures grade.
Further, the medium in the lower rear drum of temperature passes from the higher previous drum of temperature by reheating pipe, can further heat the medium in the lower rear drum of temperature like this, obtains the medium that temperature grade is higher.
Further, after heat-exchanging tube bundle parallel connection in same position in different housings, be communicated with corresponding drum, in the situation that not increasing drum quantity, heat-exchanging tube bundle in different housings is connected with same drum, just can complete the recuperation of heat of multi-series high-temperature medium, thereby save investment and the floor space of equipment.
Further, the drum that in same housing, previous heat-exchanging tube bundle connects is communicated with the import of a rear heat-exchanging tube bundle, high-temperature medium is when mobile, can further heat the medium in previous drum by a rear heat-exchanging tube bundle like this, obtain the medium that temperature grade is higher, thereby the recovery utilization rate of high-temperature medium heat energy is further improved.
Further, the heat-barrier material of inner walls setting can avoid case material directly to contact high-temperature gas, can reduce the requirement of case material.
