Description
Technical Field
The utility model belongs to the technical field of grain drying, and mainly relates to a structure for conveying waste flue gas generated in boiler combustion into a grain drying tower after high-efficiency dust removal treatment and drying grains by utilizing residual high-temperature heat energy.
Background
At present, various fuel boilers used at present, including boilers of coal, fuel oil, straw and other fuels, are treated by dust collectors after heat energy exchange in the boilers is completed by fuel combustion, and the generated combustion waste smoke is discharged into the atmosphere in a mode of being directly discharged from a boiler chimney. In practice for many years, the temperature of the waste flue gas discharged from the boiler chimney is generally 80-120 ℃, even the temperature of the waste flue gas discharged from some boiler chimneys is up to 200 ℃, namely, the waste flue gas discharged from the chimneys contains a large amount of heat energy, and the discharge mode and the structure not only improve the discharge amount of greenhouse gases, pollute and destroy the atmosphere, but also cause great loss and waste of various fuel energy sources, have low fuel utilization efficiency and greatly increase the production operation cost, and do not meet the policy requirements of energy conservation and emission reduction.
Disclosure of Invention
The utility model aims at solving the problems in the prior art, combines the actual requirements of grain drying operation, develops and designs a boiler combustion waste flue gas purifying and drying structure, and achieves the purposes of improving the fuel utilization rate, saving fuel energy, reducing grain drying operation cost and avoiding and eliminating environmental pollution by scientifically and reasonably fully utilizing the heat energy in the boiler combustion waste flue gas.
The basic design of the utility model is as follows: the utility model provides a boiler combustion waste flue gas purification stoving structure includes boiler, high-efficient dust remover, purification flue gas discharge pipeline, draught fan and cereal drying tower, the waste flue gas discharge port and the high-efficient dust remover air inlet intercommunication of boiler, the both ends of purification flue gas discharge pipeline are connected with high-efficient dust remover gas vent and draught fan air inlet respectively, communicate high-efficient dust remover and draught fan the installation purification flue gas input pipeline of intercommunication each other in the position between draught fan gas outlet and the cereal drying tower hot-blast import.
The utility model eliminates the traditional waste flue gas emission chimney for fuel combustion of various fuel boilers, directly sends clean high-temperature waste flue gas meeting the standard after being treated by the high-efficiency dust remover into the grain drying tower to be subjected to internal reference and grain drying operation, solves the problems existing in the prior art, and has the characteristics of simple, scientific and reasonable structure, high fuel utilization efficiency, fuel energy saving, low grain drying cost and no environmental pollution.

Fig. 1 is a general schematic diagram of a boiler combustion waste flue gas purifying and drying structure.
Part number description in the drawings:
1. boiler, 2, high-efficient dust remover, 3, purification flue gas discharge pipeline, 4, draught fan, 5, purification flue gas input pipeline, 6, cereal drying tower.
Detailed Description
Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. The utility model provides a boiler combustion waste flue gas purification stoving structure includes boiler 1, high-efficient dust remover 2, purifies flue gas and arranges and send pipeline 3, draught fan 4 and cereal drying tower 6, the waste flue gas discharge port of boiler 1 communicates with high-efficient dust remover 2 air inlet, purify the both ends of flue gas and arrange and send pipeline 3 and be connected with high-efficient dust remover 2 gas vent and draught fan 4 air inlet respectively, with high-efficient dust remover 2 and draught fan 4 intercommunication the installation of intercommunication each other on the position between draught fan 4 gas outlet and cereal drying tower 6 hot-blast import purifies flue gas input pipeline 5.
During operation, after the waste flue gas generated by combustion of the fuel in the boiler 1 enters the high-efficiency dust remover 2 to finish high-quality purification treatment, the obtained clean waste flue gas is directly sent into the grain drying tower 6 for reference and grain drying operation under the action of the induced draft fan 4 sequentially through the purified flue gas discharge pipeline 3, the induced draft fan 4 and the purified flue gas input pipeline 5. The temperature of waste flue gas entering the drying tower is above 80 ℃, the use requirement of grain drying on the gas temperature is met and satisfied, and the dried grains meet the national standard requirement.
