Technical field
The utility model belongs to sludge carbonizing plant field more particularly to a kind of high-temperature steam for sludge carbonization occurs
Device.
Background technology
As the spin-off of sewage, China generates 3000~40,000,000 tons of municipal sludges (moisture content is 80%) every year, in advance
The year two thousand twenty is counted, the municipal sludge yield in China is up to 6000~90,000,000 tons.Contain combustible in municipal sludge, especially
It is biochemical sludge (excess sludge that secondary settling tank excludes), due to wherein containing a large amount of activated sludge bacterium, combustible mass is more
Greatly.It is tested according to the sludge calorific value on the ground such as Shanghai, Tianjin, the calorific value in Chinese municipal sludge is about 2200~3300 big
Card/ton dry matter.Wherein postdigestive sludge calorific value is relatively low, is typically only 70% of undigested sludge or so, summer sludge
Calorific value it is lower than winter.Sludge carbonization is exactly by under sludge heating and pressurization, making the cell cracking in biochemical sludge, inciting somebody to action
Water release therein comes out, while remaining the process of carbonaceous in sludge to the maximum extent again.And sludge high temperature carbonization refers to
It is not pressurized when carbonization, temperature is 650~1000 DEG C, is about first 30% by sludge drying to moisture content, subsequently into carbide furnace height
Temperature carbonization is granulated, and carbonized particles can use as inferior fuel, calorific value be about 2000~3000 kilocalories/kilogram.
The high-temperature steam generation apparatus of existing sludge carbonization be by short circuit high temperature resistant heat-generating pipe, make its generate 800~
Then 175 DEG C of saturated vapor is passed directly into and wherein heats by 900 DEG C of high temperature, then spray 800 DEG C of left sides by nozzle
Right high-temperature steam, this mode is although simple and convenient, but short circuit high temperature resistant heat-generating pipe needs prodigious electric current, to external
Circuit proposes prodigious requirement, increases cost and the difficulty of operation, simultaneously as high temperature resistant heat-generating pipe has high current logical
It crosses, so needing to increase seal when mounted, increases the risk of short circuit, increase insecurity.
Therefore, to reduce cost, simplify operation, and safety is improved, a kind of novel high-temperature steam need to be researched and developed and filled
It sets, the effect of high temperature steam pipe is enabled to be merely possible to vapor transmission circuit, avoid high temperature steam pipe and filled as heating
The problems such as bringing high current and insulation is set, safety and working efficiency are improved.
Utility model content
The purpose of this utility model, which is to provide one kind, effectively to avoid high temperature steam pipe from bringing big electricity as heating device
The problems such as stream and insulation, improves the high-temperature steam generation apparatus for sludge carbonization of safety and working efficiency.
Technical solution：The utility model is used for the high-temperature steam generation apparatus of sludge carbonization, including is set to carbonization stove top case
On high temperature steam pipe outer cover, several steam heater units on high temperature steam pipe outer cover；The steam heating dress
It sets including high temperature steam pipe and the steam heater that is connect with the high temperature steam pipe and the steam spray on high temperature steam pipe
Mouth.
Furtherly, high temperature steam pipe is set to by steam pipe holder in high temperature steam pipe outer cover.Steam heater passes through
Steam heater holder is fixed on carbide furnace.
It further says, the inlet end of high temperature steam pipe is sealed with high temperature steam pipe outer cover by sealing porcelain ring.Steam
Heater is equipped with heat insulation foam.
Furtherly, high temperature steam pipe outer cover is equipped with several windows.The S-type loop distribution of high temperature steam pipe.It steams
It is distributed in a manner of vapour nozzle is intensive by high temperature steam pipe inlet end, end is loose.
Advantageous effect：Compared with prior art, it is the advantages of the utility model：The device divides the heating of steam and transmission
It leaves, steam is heated using steam heater, and the effect of high temperature steam pipe is merely possible to vapor transmission circuit, avoids height
The problems such as warm steam pipe brings high current and insulation as heating device, improves safety and working efficiency.

Specific implementation mode
Technical scheme of the present invention is described in further details below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, the utility model is used for the high-temperature steam generation apparatus of sludge carbonization, including is set to carbonization
If high temperature steam pipe outer covers 2 on stove top case 1, with several windows, the dry saturated steam on high temperature steam pipe outer cover 2 add
Thermal unit.The steam heater include high temperature steam pipe 3, the steam heater 4 being connect with the high temperature steam pipe 3 and
Steam jet 5 on high temperature steam pipe 3, as shown in Figure 3.Saturated vapor by becoming high-temperature steam after steam heater 4,
So that steam just reaches 800 DEG C before entering high temperature steam pipe 3, easy to operate, reduction loss greatly reduces cost.High temperature
High-temperature steam in steam pipe 3 is sprayed by steam jet 5 to Sludge Surface, its high temperature cabonization is made.The outlet of steam heater 4
Pass through flanged joint with the entrance of high temperature steam pipe 3, it is ensured that the reliability and leakproofness of the two connection.Pass through flange on window
