Part is discharged into pond in sewage plant from cooling water drainage blank pipe, and another part sprays from spray head, and in the effect of blower fan
Under so that the rate of heat dissipation in cooling water reaches maximum, because a part of water is by the discharge of cooling water drainage blank pipe, so from reclaimed water
Filling pipe carries out moisturizing, and reclaimed water supply and the cooling water from spray column output are blended in the duct so that cooling water enters one
Step cooling.When one of spray column breaks down, recirculated water can be cooled down in another spray column, Ran Houpai
Go out.
Recirculated cooling water by cooling is transported to sludge cooled region by water circulating pump, and a cooling water part first passes through
First mud heat exchanger enters back into second mud heat exchanger, and another part cooling water directly enters second from cooling water branch pipe
Individual mud heat exchanger, so it is unlikely to so that higher into second mud heat exchanger cooling water temperature.When first sludge changes
When hot device breaks down, cooling water directly can be directly entered second mud heat exchanger from cooling water branch pipe, when second
When individual mud heat exchanger breaks down, the cooling water come out from first mud heat exchanger can be directly from cooling water branch pipe
Directly enter people's circulating water region.When the failure of one of water circulating pump, can be carried out by another water circulating pump
Water conveys.
Pyrohydrolysis sludge is first transported to second mud heat exchanger by sludge pump, and sludge is by the heat exchange with cooling water
First sewage sludge storage tank is entered back into, a sludge part for first sewage sludge storage tank is transported to from sewage sludge storage tank outlet 4-1
The most top of sludge, second mud heat exchanger is reentered together with pyrohydrolysis sludge, another part sludge is from first
Sewage sludge storage tank outlet 4-3 is exchanged heat into first mud heat exchanger with cooling water, enters back into second sewage sludge storage tank,
A sludge part for second sewage sludge storage tank is transported to the most top of sludge from sewage sludge storage tank outlet 4-2, dirty with pyrohydrolysis
Mud reenters mud heat exchanger together, and another part sludge is expelled directly out from sewage sludge storage tank outlet 4-4, carried out next
Process.When one of mud heat exchanger breaks down, sludge can bypass branch pipe, another mud heat exchanger by sludge
And two sewage sludge storage tanks are used cooperatively to reach technological requirement.
Present invention disclosed above preferred embodiment is only intended to help and illustrates the present invention.Preferred embodiment is not detailed
All details are described, it is only described embodiment also not limit the invention.Obviously, according to the content of this specification,
It can make many modifications and variations.This specification is chosen and specifically describes these embodiments, is to preferably explain the present invention
Principle and practical application so that skilled artisan can be best understood by and utilize the present invention.The present invention is only
Limited by claims and its four corner and equivalent.
