Abstract
The utility model discloses a boiler blow-off residual heat utilization system. The boiler blow-off residual heat utilization system comprises a water storage tank I, a water storage tank II and a water storage tank III which are sequentially connected with a water discharge pipe; the other end of the water discharge pipe is connected with a boiler; the water storage tank III is also connected with a blow-off pipe; the other end of the blow-off pipe is introduced into a blow-off tank; the water storage tank I and the water storage tank II are also connected with the boiler through recovery pipes, and are internally provided with a coiled-tube-type preheater; and the water storage tank III is internally provided with a continuous blow-off expander. The boiler blow-off residual heat utilization system provided by the utility model has the beneficial effects that blow-off water output from the boiler firstly recovers heat through the coiled-tube-type preheater, then is treated by the continuous blow-off expander, and is input into the blow-off tank, so heat brought out by the blow-off water can be recovered effectively and is used for heating boiler water again. The boiler blow-off residual heat utilization system provided by the utility model has the advantages of simple structure, convenience in using and good residual heat recovery effect.
Description
Technical field
The utility model relates to the edible fat production technical field, especially relates to a kind of boiler blow-off bootstrap system.
Background technology
Produce in the edible oil process in the physical squeezing method, because local quality of groundwater basicity is larger, steam boiler must have larger blowdown flow rate in the production steam course, just can make a pot alkalinity of water descend to guarantee safe operation of the boiler and normal operation.Learnt by boiler feed capacity and gas production interpolation calculation, at present normal blowdown flow rate has accounted for 8% of boiler evaporating total amount, learn to produce 600 tons of steam every day, blowdown flow rate is approximately 48 tons, so large blowdown flow rate has caused the loss of a large amount of boiler afterheats, has had a strong impact on the cost benefit of enterprise.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, a kind of boiler blow-off bootstrap system is provided, native system is processed sewer successively by preheater and continuous blowdown expander, the waste heat that reclaims is used for the heating of boiler water again, the technical scheme that adopts is: a kind of boiler blow-off bootstrap system, it is characterized in that: described boiler blow-off bootstrap system comprises the water tank I that is connected successively by outlet pipe, water tank II and water tank III, the described outlet pipe other end is connected with boiler, also be connected with blow-off pipe on the described water tank III, the other end of described blow-off pipe is passed in the blowdown pond, described water tank I is connected by recovery tube with the water tank II and is connected with described boiler, be provided with the coiled preheater in described water tank I and the water tank II, be provided with continuous blowdown expander in the described water tank III.
Technical characterictic of the present utility model also has: also be provided with water pump on the described recovery tube.
The beneficial effects of the utility model are: the sewer of exporting from boiler at first reclaims heat through the coiled preheater, and then sewer is input in the blowdown pond after processing through continuous blowdown expander, like this, the heat of taking out of by sewer can be used for again by limited recovery the heating of boiler water.The utlity model has advantage simple in structure, easy-to-use, that waste heat recovery is effective.
