Steam is introduced in heating tube bundle the brown coal to falling in housing and carries out indirect preheating, and what is produced in lower heating tube bundle warm is cold
Lime set is separated and collected in gas-liquid separation room, and the steam after separation condensed fluid goes successively to heating tube bundle and further changes with brown coal
Heat, the condensed fluid of the generation in upper heating tube bundle warm is collected interior and is separated and collected in fixed gas, realizes the heat of steam
Can be with the recovery of water resource；(2) baffle plate is set between upper and lower heating tube bundle, and the steam that brown coal are volatilized rises to multilamellar friendship
The baffle plate of mistake arrangement and then condensation, condensed fluid collects inflow dirt liquid and collects separation chamber along this baffle plate, makes pre-dried condensed fluid
Utilization can be recycled, water source money is further reclaimed, mitigates environmental pollution.
The baffle plate is preferably inverted " v ", multi-layer intercrossed arrangement, it is ensured that brown coal granule can be passed through without blocking up
Material.All baffle plates have downward inclination angle (preferably 0.36~1.62 °) along separation chamber directions are collected, it is ensured that the drop of condensation can be with
Smoothly collect and flow into collection chamber receiving condensate.The scope of v-angle can be at 60~140 °, it is ensured that will not be because of the obstruction of two flanks
Material is caused to flow down difficulty.
Steam condensate smoothly collects cocurrent and enters gas-liquid separation in order to ensure bottom moisture condensation room and top exhaust gas chamber
Room and on-condensible gas collecting chamber, the upper and lower heating tube bundle is downward-sloping along gas flow direction, and its level inclination is 0.36
~1.62 °.
Beneficial effect
(1) this utility model reduces factory's heat negative using the energy preheating brown coal entrained by the steam escaped in exsiccator
Lotus (more than 45%), it is energy-saving；
(2) while, the moisture escaped in exsiccator can be reclaimed, fully recycle water resource valuable in brown coal, can
To reclaim more than the 43% of brown moisture in coal；
(3) steam that brown coal are volatilized in preheater can be reclaimed, it is to avoid brown coal are on the top of preheater because on absorbing
Rise steam and build bridge, cause brown coal granule smoothly to flow down discharge.
(4) this utility model simple structure, can efficient recovery dry steam heat energy and water resource, operating cost it is low, peace
It is complete reliable.

Section is inverted V-shaped, and angle b is 60~140 °.
Operation principle：
Raw material brown coal (water content 30wt%) are continuously added to from charging aperture 1, in heating tube bundle 7 and the pipe on first Jing of flowing downward
Interior steam is exchanged heat, and then the multi-layer intercrossed arrangement baffle plates 12 of Jing are uniformly distributed, then the steam under Jing in heating tube bundle 8 and pipe
Further heat exchange, brown coal temperature can reach 46 DEG C when reaching discharging opening 2, and water content can be down to 20wt%, finally from bottom
Discharging opening 8 is continuously discharged into follow-up exsiccator and is further dried.
Steam in brown coal warm rises to the baffle plate 12 of uniform interlaced arrangement, is blocked and is formed condensed fluid attachment
In the lower surface of baffle plate 12, the dust-laden condensed fluid that baffle plate 12 is collected flows into dirt liquid and collects separation chamber 6, and in dirt liquid separation chamber 6 is collected
In further carry out dirt liquid separation, collect condensed fluid；
On the other hand, it is equal that the steam (105 DEG C, 0.1MPa) drawn in exsiccator enters steam cloth air chamber 7 by air inlet 11
Lower heating tube bundle 9 is entered after cloth by the hypomere of housing 1 to exchange heat with the brown coal in housing 1, here undergoes phase transition condensation, discharges heat
Heating brown coal, subsequently into gas-liquid separation chamber 4 condensed fluid in steam is separated, and fixed gas enters back into housing 1 by gas-liquid separation chamber 4
The upper heating tube bundle 8 of epimere further to preheating brown coal, is further separated out condensed water, no subsequently into fixed gas collecting chamber 5
Solidifying gas is discharged in the presence of air-introduced machine by air-vent 10, and now gas temperature is (40 DEG C).
The gas-liquid separation chamber 4 and fixed gas collecting chamber 5 and the condensed fluid in steam cloth air chamber 7 can be discharged by bottom,
Dirt liquid collects the dust-laden condensed fluid collected in separation chamber 6 Jing after settlement separate, and mud, top overflow clear liquor are discharged in bottom.
