Background technology
The production of steam pressure cement concrete product is a kind of process of using the still kettle batch production, after finishing the product steam pressure at every turn, waste vapour (saturated vapor that contains ash content and peculiar smell) in emptying a large amount of still in vain all, blowdown presssure 0.5～1.2Mpa does not wait (vapour that falls between still is low when utilizing, and the vapour that do not fall is high when utilizing).160～192 ℃ of its waste vapour temperature belong to high-grade heat energy, and the waste vapour discharge capacity is 30～60% of product steam consumption approximately, and waste steam exhausting not only causes the huge waste of heat energy, and the noise when ash content wherein, peculiar smell and discharging also severe contamination plant area and surrounding environment.The emptying heat-energy losses of a large amount of waste vapour is so that boiler heating system heat utilization rate less than 30%.
The current steam pressure waste vapour UTILIZATION OF VESIDUAL HEAT IN state of the art: most enterprises are not enough to the heat content understanding of waste vapour, add that power-saving technology lacks, and the waste vapour waste heat does not obtain utilizing substantially; Indivedual enterprises understand and adopt simple normal pressure heat exchange mode, enter boiler after utilizing a part (about 1/3) waste vapour heating boiler feed temperature to 60～80 ℃, reach certain energy-saving effect (about 10%), but 2/3 waste vapour waste heat are still by emptying in vain.
Summary of the invention
In order to overcome the now deficiency of above technology existence, the utility model provides a kind of steam pressure waste vapour waste heat secondary recovery simple in structure, safe and reliable, the efficient utilization of waste vapour waste heat to utilize energy saver.
The purpose of this utility model solves in the current steam pressure cement concrete product production process that steam pressure waste vapour waste heat is not recycled or the low problem of utilization rate, improves the boiler heating system heat utilization rate, reduces or eliminates waste steam exhausting and pollutes, and reaches energy-conserving and environment-protective.
The technical scheme that the utility model technical solution problem adopts is: a kind of steam pressure waste vapour waste heat secondary recovery is utilized energy saver, its bag water pipe, water pump, boiler, still kettle, it is characterized in that: described pump intake one side is provided with secondary waste vapour waste-heat recoverer, and the pump outlet opposite side is provided with one-level waste vapour waste-heat recoverer; Described still kettle waste steam exhausting pipe is connected with the coil pipe of one-level waste vapour waste-heat recoverer, secondary waste vapour waste-heat recoverer successively.
Waste steam exhausting pipe between described one-level waste vapour waste-heat recoverer and the secondary waste vapour waste-heat recoverer is provided with control valve.
The beneficial effects of the utility model are: 1. energy-saving effect makes feed temperature be increased to 120～160 ℃ from 25 ℃ of normal temperature, boiler energy-saving 22～32%; 2. environment protecting makes the discharging of waste vapour approach zero, and air pollution and noise pollution are thoroughly eliminated, and the waste vapour condensation water that contains ash content and peculiar smell is recovered to the batch plant utilization, turns waste into wealth; 3. enhance productivity, boiler output can increase by 22～32%, and heating system efficient improves, every still steam pressure time shorten 15～30 minutes.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Shown in the figure: 1. secondary waste vapour waste-heat recoverer, 2. control valve, 3. one-level waste vapour waste-heat recoverer, 4. still kettle, 5. boiler, 6. water pump, 7. water pipe, 8. waste steam exhausting pipe, 9. coil pipe.
The specific embodiment
As shown in Figure 1, a kind of steam pressure waste vapour waste heat secondary recovery is utilized energy saver, its bag water pipe 7, water pump 6, boiler 5, still kettle 4.Water pump 6 water inlets one side is provided with secondary waste vapour waste-heat recoverer 1, and water pump 6 delivery port opposite sides are provided with one-level waste vapour waste-heat recoverer 3; Still kettle 4 waste steam exhausting pipes 9 are connected with the coil pipe 9 of one-level waste vapour waste-heat recoverer 3, secondary waste vapour waste-heat recoverer 1 successively.Waste steam exhausting pipe 8 between one-level waste vapour waste-heat recoverer 3 and the secondary waste vapour waste-heat recoverer 1 is provided with control valve 2.
The utility model work is original: 1. waste vapour flows to: the waste vapour that still kettle 4 is discharged at first enters one-level waste vapour waste-heat recoverer 3 and carries out the heat exchange first time with boiler feedwater, then after control valve 2 throttlings, enter secondary waste vapour waste-heat recoverer 1 and carry out the heat exchange second time with boiler feedwater, become at last condensation water and discharge.2. boiler feedwater flows to: flow to contrary with waste vapour, form reverse heat-exchange, be that boiler feedwater at first is heated to 60～80 ℃ in secondary waste vapour waste-heat recoverer 1, then squeeze into through boiler feed pump 6 and enter boiler 5 after 3 continuation of one-level waste vapour waste-heat recoverer are heated to 120～160 ℃ by relay.3. secondary waste vapour waste-heat recoverer 1 is non-pressure vessel, and one-level waste vapour waste-heat recoverer 3 is pressure resistant vessel, and the two-stage recover all has heat exchange, accumulation of heat integrated function.
