Background technology
Dry coke quenching makes as the mature technology for recycling red coke, primary dedusting technique ash cooling equipment in production in coking industry
Frequently cause the problems such as slagging, leakage due to heat exchange tube leakage in, constrains the steady production rhythm of dry coke quenching, occur
Because technological requirement is limited after leakage, dry coke quenching production need to be stopped and complete cooling equipment replacement, such unplanned replacement maintenance is usually
It during being happened at dry coke quenching continuous production, is not only impacted to the safety of system, and because replacing narrow space, replacing position
Risk factor is more, and adverse effect is brought to the continuous-stable and safe direct motion of dry coke quenching production.
Utility model content
It is primary to solve dry coke quenching the purpose of this utility model is to provide a kind of dry coke quenching primary dedusting ash cooling device
Dust collecting process ash cools down cooling discontinuous problem caused by equipment slagging, leakage.
In order to solve problem above, technical solutions of the utility model are：
A kind of dry coke quenching primary dedusting ash cooling device, including inner sleeve heat exchanger tube, housing heat exchanger tube, coke powder channel, inner sleeve
Interlayer between heat exchanger tube and housing heat exchanger tube is coke powder channel, and unloading valve, housing heat exchanger tube inner circumferential are equipped with below coke powder channel
Equipped at least two second snakelike heat exchange tubes, every second snakelike heat exchange tube is equipped with the second water inlet and the second water outlet, inner sleeve
The first snakelike heat exchange tube is equipped in heat exchanger tube, the first water inlet and the first water outlet of the first snakelike heat exchange tube pass through coke powder channel
With housing heat exchanger tube, the first water outlet, the first water inlet, the second water inlet, the second water outlet are each provided at housing heat exchange pipe outer wall.
Further, protection pipe is equipped between housing heat exchanger tube and coke powder channel.
Further, the second snakelike heat exchange tube is 2-6, is distributed on the inside circumference of housing heat exchanger tube.
Further, inner sleeve heat exchanger tube and the integrated poured molding of the first snakelike heat exchange tube.
Further, housing heat exchanger tube and the integrated poured molding of the second snakelike heat exchange tube.
The beneficial effects of the utility model are as follows：The utility model inside inner and outer sleeves heat exchanger tube by being arranged snakelike change
Heat pipe is increasing heat exchange area, is extending cooling water residence time in heat exchange, heat exchange efficiency improved, even if snakelike heat exchange tube
There is poorly sealed or breakage, also there is inner and outer sleeves heat exchanger tube to be contacted with coke powder as protective tube blocking cooling water leakage, cause
Slagging；The setting of protection pipe further prevents cooling water to be contacted with coke powder；Inner and outer sleeves heat exchanger tube and snakelike heat exchange tube are integrated poured
Molding, ensures the leakproofness of tube body；The utility model is simple in structure, easy to make, security risk is low, economic benefit is apparent.
