Specifically, air draft system 9 specifically includes the components such as air blower 10, air inlet and the discharging of air draft system 9 store vehicle
Between 01 connection, to being extracted to the air inside discharging storage workshop 01.Boiler is commonly equipped with pressure fan, after extraction
Air can be entered in the boiler of power plant by the first gas outlet and pressure fan, mix burning with sludge in donkey boiler and coal-fired.
Air after extraction can also drain into outdoor environment by the second gas outlet, it is possible to understand that, the sky in discharging storage workshop 01
Gas needs to be cleared up using activated carbon adsorption device 11 or other devices before being expelled to outdoor, removes the peculiar smell in gas, keeps away
Exempt to cause environmental pollution.
Optionally, the air inlet of air draft system 9 is also connect with first conveyer belt 3 or the second conveyer belt 7 or storage bin 5.By
It is all made of enclosed construction in first conveyer belt 3 and the second conveyer belt 7, inner air is easy to be influenced by sludge, while closed
Air in space is inevitably leaked by feeding mouth and discharge port to discharging storage workshop 01.Therefore air draft system 9 can also lead to
It crosses associated pipe to connect with first conveyer belt 3, the second conveyer belt 7, so that the two is formed tiny structure, to avoid first conveyer belt 3
It is escaped with the peculiar smell in the enclosure space of the second conveyer belt 7.The air inlet of air draft system 8 can also be connect with storage bin 5, make storage
Feed bin 5 is in micro-vacuum state, avoids distributing for peculiar smell.
It should be understood that during sludge is transported to boiler and carries out mixing burning, boiler can scavenge to outside,
It usually requires to be dusted exhaust gas and desulfurization process in actual production process.Such as can specifically use low-carbon combustion device and
SCR denitration is dusted processing using electrostatic precipitator and wet electrical dust precipitator.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
