Abstract
The utility model discloses a waste heat recovery system of a boiler and a still kettle, which is characterized by comprising a sewage tank, a water reducing tank and a soft water tank, wherein snake-shaped heat exchange tubes are distributed in the sewage tank and the water reducing tank; a collecting plate distributed with countless small holes is arranged above the soft water tank; the sewage tank, the water reducing tank and the soft water tank are communicated in sequence through soft water tubes; an inlet of the sewage tank is connected with a sewage tube of the boiler, and an outlet of the sewage tank is communicated with a circulating pool; an inlet of the water reducing tank is communicated with a condensing water tube of the still kettle, and an outlet of the water reducing tank is communicated with the circulating pool; and the soft water tank is communicated with a steam returning and distributing cylinder through a steam tube. By using the waste heat recovery system of the boiler and the still kettle, the consumption of boiler fuels and the use level of soft water are reduced, and the production cost of steam is lowered; and since the water quality of the boiler is improved, the pollution discharge heat loss of the boiler can also be reduced, and the efficiency of the boiler is greatly improved.
Description
Technical field
The utility model relates to the reclaimer of a kind of boiler, still kettle waste heat.
Background technology
The steam waste heat of boiler, still kettle and the recycling of condensed water are an energy-saving and emission-reduction job of benefiting the nation and the people.At present, the steam heating system inefficiency of China, the energy, water resource waste are serious, and it is the main cause that causes inefficiency that steam waste heat wherein, condensed water all do not have the recycling of science.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler, still kettle residual neat recovering system that can fully reclaim steam waste heat, condensed water.
The technical solution adopted in the utility model is: a kind of boiler, still kettle residual neat recovering system, it is characterized in that: comprise foul water tank, diminishing case, softened water tank, be distributed with snakelike heat exchange tube in described foul water tank, the diminishing case, there is the collecting board of the countless apertures that distribute the top of softened water tank, and described foul water tank, diminishing case, softened water tank communicate successively by hose; The import of foul water tank connects the sewage pipe of boiler, and outlet communicates with the gas wash tower circulatory pool; The import of diminishing case communicates with the condensate pipe of still kettle, and outlet communicates with the gas wash tower circulatory pool, and softened water tank communicates by steam pipe and back-steam gas-distributing cylinder.
The utility model has reduced boiler oil consumption, has also reduced the consumption of demineralized water, reduces the production of steam cost, and because the water correction of boiler, also can reduce the blowdown heat loss of boiler, has improved the efficient of boiler greatly.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Among the figure, the 1st, boiler, the 2nd, still kettle, the 3rd, foul water tank, the 4th, gas wash tower circulatory pool, the 5th, water film dedusting tower, the 6th, back-steam gas-distributing cylinder, the 7th, softened water tank, the 8th, diminishing case, the 9th, boiler softened water tank.
The specific embodiment
The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:
As can be seen from Figure 1, the utility model boiler, still kettle residual neat recovering system comprise foul water tank, diminishing case, softened water tank, gas wash tower circulatory pool, back-steam gas-distributing cylinder, and foul water tank, diminishing case, softened water tank communicate successively by hose; The import of foul water tank connects the sewage pipe of boiler, and outlet communicates with the gas wash tower circulatory pool; The import of diminishing case communicates with the condensate pipe of still kettle, and outlet communicates with the gas wash tower circulatory pool, and the back-steam gas-distributing cylinder communicates with softened water tank, diminishing case successively by steam pipe.Be distributed with snakelike heat exchange tube in foul water tank, the diminishing case, there is the collecting board of the countless apertures that distribute the top of softened water tank.
The course of work: boiler blowdown water is stored in the foul water tank, and by absorbing the heat of sewer, the soft water temperature can improve about 20 degree in the snakelike heat exchange tube of soft water in the foul water tank, and the sewer temperature is discharged in the gas wash tower circulatory pool after reducing; Autoclave condensation water is discharged in the diminishing case, the snakelike heat exchange tube in the diminishing case is by the heat of absorption condensation water once more for soft water, and the soft water temperature is elevated to about 60 degree, after condensed water sucks heat, be extracted in the gas wash tower circulatory pool with water pump, soft water flows in the soft water storage bin; Flash steam directly is discharged in the soft water storage bin and heats, and the soft water temperature is elevated to about 70 degree, is extracted in the boiler soft water storage bin with pump, and boiler of feeding uses; Water water infusion in the gas wash tower circulatory pool is gone into dedusting in the moisture film gas wash tower, desulfurization, the water ph value of discharging because of boiler, still kettle can directly be removed sulfur dioxide and dust in the boiler emission flue gas all more than 10, save simultaneously and use NaOH to add in the pond, it is qualified to guarantee to discharge.
