Abstract
The utility model relates to a drying cylinder tail gas energy recovering system used for recovering energy in papermaking or similar industries. The system comprises an energy recoverer (1), a drying cylinder gas hood (2), a drying cylinder (3), a feeding pump (4) and a steam line (5), wherein hot air discharged from the drying cylinder gas hood (2) is connected to the energy recoverer (1); condensed water discharged from the drying cylinder (3) is connected to the feeding pump (4); condensed water discharged from the feeding pump (4) is connected to the energy recoverer (1); and steam discharged from the energy recoverer (1) is directly input to the drying cylinder (3) or the steam line (5). The drying cylinder tail gas energy recovering system provided by the utility model has the advantages that energy carried in the tail gas of the drying cylinder is absorbed through the energy recoverer and steam of 4-14kg is produced by using the recovered energy. The produced steam can be directly input to the drying cylinder or the steam line, and thus, the recovered heat energy is utilized.
Description
Technical field
The utility model relates to a kind of drying cylinder tail gas energy recovery system.The energy that is used for papermaking or similar industry reclaims.
Background technology
In papermaking or similar industry drying section is arranged all, the main energy consumption equipment of drying section is a drying cylinder, and its energy consumption comprises two parts: 1, the steam of 4 ~ 6 kilograms of pressure of the inner input of drying cylinder; 2, the drying cylinder gas hood is imported 200 ~ 700 ℃ hot blast.By the paper pulp (or analog) of being dried thus the condensation latent heat that absorbs the drying cylinder steam inside evaporate moisture and reach dry purpose, evaporate the moisture that and taken away by the hot blast of drying cylinder gas hood, self temperature decreased when hot blast absorbed moisture, water capacity increases.Thereby influence drying effect in order to prevent that water capacity continues to increase in the hot blast; Except a part of hot blast internal system circulation; Some hot blast is discharged system; And the hot blast temperature of this part discharge very high (200 ~ 500 ℃) has considerable waste heat, if considerable economic will be arranged to this part waste heat recovery.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of drying cylinder tail gas energy recovery system that can reclaim the energy of drying cylinder tail gas is provided.
The purpose of the utility model is achieved in that a kind of drying cylinder tail gas energy recovery system, and said system comprises recuperator, drying cylinder gas hood, drying cylinder, feed pump and steam pipework, and 200 ~ 500 ℃ of hot blasts that the drying cylinder gas hood is discharged insert recuperator; The water that coagulates that goes out drying cylinder inserts feed pump, and the water that coagulates that goes out feed pump inserts recuperator, and the steam that goes out recuperator is directly imported drying cylinder or incorporated steam pipework into.
The utility model drying cylinder tail gas energy recovery system, the heat transfer component of said recuperator adopts heat pipe.
The utility model drying cylinder tail gas energy recovery system, said inside heat pipe working medium can amount adopt the equal difference mode of successively decreasing.
The utility model drying cylinder tail gas energy recovery system, said heat pipe adopts finned tube.
The utility model drying cylinder tail gas energy recovery system, the sleeve structure form is adopted in the steam generation zone of said heat pipe.
The beneficial effect of the utility model is:
The utility model drying cylinder tail gas energy recovery system has absorbed the energy that drying cylinder tail gas carries through recuperator, and with the steam of 4 ~ 14 kilograms of the energy production that reclaims.The steam that produces can directly be imported drying cylinder or incorporate steam pipework into.The heat energy that reclaims has so just had purposes.

The specific embodiment
Referring to Fig. 1, Fig. 1 is the general structure sketch map of the utility model drying cylinder tail gas energy recovery system.Can find out by Fig. 1; The utility model drying cylinder tail gas energy recovery system; Said system comprises: recuperator 1, drying cylinder gas hood 2, drying cylinder 3, feed pump 4 and steam pipework 5, and 200 ~ 500 ℃ of hot blasts that drying cylinder gas hood 2 is discharged insert recuperator 1, and the water that coagulates that goes out drying cylinder 3 inserts feed pump 4; The water that coagulates that goes out feed pump 4 inserts recuperator 1, and the steam that goes out recuperator 1 is directly imported drying cylinder 3 or incorporated steam pipework 5 into.
200 ~ 500 ℃ of hot blasts of discharging from drying cylinder gas hood 2 get into recuperator 1, and after recuperator 1 absorbed the heat of hot blast, the hot blast temperature of discharge decreased; Drying cylinder 3 coagulates water or other soft water and gets into recuperator 1 through feed pump 4 back of boosting, and recuperator 1 discharges the heat that absorbs from hot blast to soft water, and the water temperature back that raises produces 4 ~ 14 kilograms steam; The steam that produces can directly be imported drying cylinder 3 or incorporate steam pipework 5 into.
Recuperator in the utility model adopts heat pipe intensified heat transfer technology but is not limited to hot pipe technique, can adopt other new technologies according to the difference of design condition.The characteristics of heat pipe steam generator comprise: inside heat pipe working medium can amount adopts the equal difference mode of successively decreasing, and the outside fin reinforcing that adopts of heat pipe conducts heat, and the fin reinforcing heat transfer technology guarantees the tail gas energy high efficiente callback, and the sleeve structure form is adopted in heat pipe steam generation zone.The main boiling heat transfer that adopts between heat pipe steam generator and the water.
