A kind of hydrolysis kettle vapor recycle device
Technical field
The utility model relates to a kind of chemical industry firing equipment, relates in particular to a kind of hydrolysis kettle vapor recycle device.
Background technology
The hydrolysis kettle vapor recycle device that uses comprises two hydrolysis kettles at present, air inlet, the decompression exhaust mouth, air inlet pipe, waste gas was directly discharged from the decompression exhaust mouth after decompression exhaust pipe, steam entered hydrolysis kettle from air inlet, and the waste gas that discharge this moment has higher temperature, not only waste energy after directly discharging, also can shine into environmental pollution.
Summary of the invention
The purpose of this utility model provides a kind of energy savings, the hydrolysis kettle vapor recycle device of environmental protection.
The technical solution of the utility model is: a kind of hydrolysis kettle vapor recycle device, it comprises hydrolysis kettle, air inlet pipe, the decompression exhaust pipe, air inlet, the decompression exhaust mouth, it is characterized in that: described hydrolysis kettle is two, the second decompression exhaust mouth, 11 places at second hydrolysis kettle 9 are provided with the first waste gas inlet pipe 4 that is connected with first air inlet 2 of first hydrolysis kettle 1, this first waste gas inlet pipe 4 is provided with second valve 6, the first decompression exhaust mouth, 3 places at first hydrolysis kettle 1 are provided with the second waste gas inlet pipe 12 that is connected with second air inlet 10 of second hydrolysis kettle 9, this second waste gas inlet pipe 12 is provided with the 4th valve 14, described first air inlet 2 is provided with first valve 5, and the described second decompression exhaust mouth is provided with the 3rd valve 13.
The beneficial effects of the utility model are: the waste gas inlet pipe that utilizes the decompression exhaust mouth of hydrolysis kettle to be connected with the air inlet of another hydrolysis kettle; the waste gas residual heat of discharging is carried out heating hydrolysis to another hydrolysis kettle; waste gas is made full use of; saved steam; thereby saved the energy, protected environment.
