Description
Technical field
The utility model relates to a kind of using waste heat from tail gas recycling device.
Background technology
In chemical production processes and in the high temperature coal burning device fabrication process; The capital produces great amount of heat, the residual a large amount of waste heats of meeting in the tail gas that equipment produces, and these tail gas directly are discharged in the air can cause heat waste; Therefore need a kind of equipment with the residual heat collection recycling in the tail gas; Utilize waste heat to produce steam in the traditional device, in the equipment heat exchanger has been installed and drum utilizes waste heat, but still be not enough to utilize completely heat like this; Once exchange is difficult to cause the recovery fully of heat, so the utility model is made improvement again on the traditional device basis.
The utility model content
The utility model provides a kind of can absorb the using waste heat from tail gas recycling device that reclaims using waste heat from tail gas fully.
The utility model technical solution problem provides following scheme:
A kind of using waste heat from tail gas recycling device comprises boiler, heat exchanger, soft water preheater, drum; Establish inlet, liquid outlet and admission opening on the said drum, said boiler bottom is established tail gas import and air intlet, and flue gas discharge opening is established on the top; Heat exchanger is established at said boiler middle part, and said heat exchanger is provided with drum downspout and Steam Pipe, the liquid outlet of said drum downspout UNICOM drum; Said Steam Pipe UNICOM steam bubble admission opening, soft water preheater is established in said heat exchanger top, establishes soft water import and soft water outlet on the said soft water preheater; Said soft water import and demineralized water tank UNICOM, said soft water outlet UNICOM drum inlet.
The utility model feeds the import of tail gas from tail gas in use, and air feeds from air intlet; Gas rises after both mixed combustions, through over-heat-exchanger, soft water heating back is produced steam be passed in the drum; The heat exchanger top is provided with soft water preheater, cold soft water is added to from demineralized water tank carry out preheating in the soft water preheater earlier, the soft water after the preheating is passed in the steam bubble again; The heat that makes heat exchanger fail to make full use of like this is able to the secondary exchange, and heat is utilized fully.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, a kind of using waste heat from tail gas recycling device comprises boiler 1, heat exchanger 2, soft water preheater 3, drum 4; Establish inlet 5, liquid outlet 6 and admission opening 7 on the said drum 4, tail gas import 8 and air intlet 9 are established in said boiler 1 bottom, and flue gas discharge opening 10 is established on the top; Heat exchanger 2 is established at said boiler 1 middle part; Said heat exchanger 2 is provided with drum downspout 11 and Steam Pipe 12, the liquid outlet 6 of said drum downspout 11 UNICOM's steam bubbles 4, said Steam Pipe 12 UNICOM's drum admission openings 7; Soft water preheater 3 is established in said heat exchanger 2 tops; Establish soft water import 13 and soft water outlet 14 on the said soft water preheater 3, said soft water import 13 and demineralized water tank UNICOM, said soft water outlet 14 UNICOM's drum inlets 5.
Claims (1)
