Abstract
The utility model relates to a hazardous waste incineration waste heat boiler. A boiler body is formed by combining a high-temperature segment flue of a vertical structure and a low-temperature segment flue of a horizontal structure. The high-temperature segment flue is communicated with the low-temperature segment flue and arranged at the front end of the low-temperature segment flue. The wall of the high-temperature segment flue and the wall of the low-temperature segment flue are respectively of a membrane wall structure. Multiple rows of convection banks are arranged in the low-temperature segment flue. The front end of the boiler body is provided with a flue gas inlet. The rear end of the boiler body is provided with a flue gas outlet. According to the hazardous waste incineration waste heat boiler, a U-shaped channel which descends and ascends can be used for effectively separating soot from flue gas; the high-temperature segment flue of the boiler body adopts the membrane wall structure, thereby being capable of transferring heat effectively and preventing the soot from blocking the flues; the convection banks are arranged in the low-temperature segment flue behind the boiler body, therefore, the heated area of the membrane wall can be reduced, and the overall steel consumption of the boiler body is lowered.

Technical field
The utility model relates to a kind of danger wastes waste gas of incineration boiler.
Background technology
At present, the hazardous waste disposal route by landfill or the simple and easy burning at initial stage, develops into burning, the gasification and melting technology of energy recovery type along with the passing of expanding economy and time.The whole technological process of burning requires the necessary reliable and stable operation of each subsystem, bootstrap system wherein, namely waste heat boiler, be even more important to the treatment process after dangerous waste incineration, because it both had been connected smoke processing system, also be related to lime-ash processing, bootstrap system.
The structure of existing waste heat boiler is not considered the smoke characteristic after danger wastes burns, can not fine smoke treatment in strong bonding ash stick to situation on heating surface, more worsen as ruuning situation, can stop up flue, cause the boiler can not stable operation.
Summary of the invention
The purpose of this utility model is, deficiency for the prior art existence, a kind of danger wastes waste gas of incineration boiler is provided, the flue gas that it is discharged after utilizing danger wastes to burn produces steam by the boiler heating surface heat exchange, flue gas circulates smooth and easy in flue and does not stop up flue, and the flying dust in the most of flue gas of sedimentation, reduce the cigarette temperature and satisfy the subsequent technique demand.
The technical solution of the utility model is, a kind of danger wastes waste gas of incineration boiler, boiler be the low-temperature zone flue of the high temperature section flue of vertical structure and horizontal type structure in conjunction with layout, the high temperature section flue is communicated with the low-temperature zone flue and the high temperature section flue is placed in the front end of low-temperature zone flue; The walling of flue of described high temperature section flue and low-temperature zone flue is membrane wall structure, arranges many rows convection bank in the low-temperature zone flue, and the front end of described boiler is provided with gas approach, and the rear end of boiler is provided with exhanst gas outlet.
The bottom of high temperature section flue is provided with high temperature section flue ash bucket, and the bottom of low-temperature zone flue is provided with low-temperature zone flue ash bucket.
The walling of flue of described high temperature section flue comprises front wall membrane wall, rear wall membrane wall and and be connected the left side wall membrane wall of front wall membrane wall, rear wall membrane wall, right-side wall membrane wall and connects the mid-board membrane wall of both walls membrane wall, and above-mentioned membrane wall forms the U-shaped flue jointly.Every membrane wall is connected to form closed circuit through rising, decline pipeline and drum respectively, can guarantee the good effect of heat exchange of every membrane wall.
Every row's convection bank comprises that upper collecting chamber, lower header and connection upper collecting chamber be connected many light pipes that are heated of lower header, and is provided with flexible steel in flat section tubing in the lower header bottom, and flexible steel in flat section tubing distributes header to be connected with the down-comer of boiler.
Described lower header is provided with for the be heated mechanical vibrator mechanism of dust stratification on light pipe of removing.
As known from the above, the utility model waste heat boiler has following characteristics: utilize the U-shaped passage capable of being that descends with rising to realize that effectively the flue dust in flue gas separates; Boiler high temperature section flue adopts membrane wall structure, not only effectively heat transfer but also can avoid flue dust to stop up flue; Arrange convection bank in the low-temperature zone flue of boiler back, can reduce the membrane wall heating surface area, reduce boiler overall steel consumption.
