Abstract
The utility model relates to a boiler tail gas waste heat utilization system used for production. The utilization system comprises a boiler and a soft water tank and further comprises a heat exchanger, wherein the soft water tank and a shell pass water inlet end of the heat exchanger are connected through a pipeline, a tail gas exhaust end of the boiler and a pipe pass air inlet end of the heat exchanger are connected through a pipeline, a shell pass water outlet end of the heat exchanger and a water inlet end of the boiler are connected through a pipeline. The boiler tail gas waste heat utilization system used for the production can effectively improve tail gas waste heat utilization efficiency, is simple in structure and can be used widely.
Description
Technical field
The utility model relates to a kind of using waste heat from tail gas and utilizes system, relates in particular to a kind of production and utilizes system with waste heat of boiler tail gas.
Background technology
The system of utilizing of waste heat of boiler tail gas for existing production, normally realize by economizer.Because the heat exchange area of economizer is limited, and soft water walks tube side, and the water yield stored in pipe is limited, and heat exchanger time when pump is carried water between soft water and tail gas is short, and the temperature that soft water promotes is not obvious, causes the boiler hot utilization ratio low.
The utility model content
In order to overcome the existing low problem of using waste heat from tail gas utilization ratio of utilizing system of producing with waste heat of boiler tail gas, the utility model provide a kind of using waste heat from tail gas utilization rate high the system of utilizing of waste heat of boiler tail gas for production.
The technical scheme in the invention for solving the technical problem is: a kind of production utilizes system with waste heat of boiler tail gas, comprise boiler, demineralized water tank, also comprise heat exchanger, the shell side water inlet end of described demineralized water tank and heat exchanger is connected by pipeline, and the tube side inlet end of described boiler exhaust gas outlet side and heat exchanger is connected by pipeline; The shell side water side of described heat exchanger is connected by pipeline with the boiler feed water end.
In order better to supplement soft water, the horizontal level of described demineralized water tank is higher than heat exchanger.
Preferably, be provided with pump on the shell side water side of described heat exchanger and the pipeline between the boiler feed water end.
In order better to process waste gas, protection of the environment, described heat exchanger tube side exhaust end is connected with eluting column, and is provided with pump between the two.
The utility model beneficial effect: change economizer into heat exchanger, hot-air is walked tube side, and soft water is walked shell side, due to the increasing of heat exchange area, makes using waste heat from tail gas be fully utilized.Demineralized water tank is arranged on to a high position and supplements constantly soft water, make the soft water of shell side remain full shelly state, so a large amount of soft water is exchanged with the using waste heat from tail gas with boiler constantly, further guarantees taking full advantage of of using waste heat from tail gas.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is this practical structural representation.
The specific embodiment
Consult Fig. 1, a kind of production as shown in Figure 1 utilizes system with waste heat of boiler tail gas, comprise boiler 1, demineralized water tank 2, also comprise heat exchanger 3, the shell side water inlet end of described demineralized water tank 2 and heat exchanger 3 is connected by pipeline, and the tube side inlet end of described boiler 1 tail gas outlet side and heat exchanger 3 is connected by pipeline; The shell side water side of described heat exchanger 3 is connected by pipeline with boiler 1 water inlet end.The horizontal level of described demineralized water tank 2 is higher than heat exchanger 3.Be provided with pump 4 on pipeline between the shell side water side of described heat exchanger 3 and boiler 1 water inlet end.Described heat exchanger 3 tube side exhaust ends are connected with eluting column 5, and are provided with pump 4 between the two.
In process of production, cold soft water is injected to demineralized water tank, then the soft water in demineralized water tank is injected to the shell side of heat exchanger.The hot exhaust gas produced in boiler for producing is sent in the tube side of heat exchanger by pipeline.Like this, soft water and the hot exhaust gas in tube side in shell side carry out heat exchange, and the soft water that then will absorb using waste heat from tail gas injects boiler, carries out the secondary utilization.Simultaneously, the tail gas that there is no what waste heat is entered to eluting column or other place is processed.
