A kind of brown coal oven dry/low-temperature pyrolysis equipment of steam heat conduction, this equipment include and continue the drying shed that is communicated with more than two mutually; Be provided with heating unit in each drying shed, be provided with condensate drain outlet in the drying shed bottom; Each drying shed feeds steam by inlet pipe, is communicated with the inlet pipe of next drying shed by escape pipe, is communicated with follow-up drying shed by that analogy.
Further, be provided with automatic admission valve between the escape pipe of adjacent connection and inlet pipe.
Further, condensate drain outlet connects a water discharge valve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model drying technology is to be heating agent with the superheated vapour, and compared with prior art, the beneficial effects of the utility model are:
1. be heating agent with the superheated vapour, make inflammable brown coal material in drying process, not contact oxygen, do not have the danger of burning, blast, safe.
2. as the superheated vapour thermal conductivity height of heating agent, the drying efficiency height.
3. the brown coal material is in the oven-dried condition of static property in drying shed, is conducive to the modification of brown coal particle, and the brown coal particle volume is dwindled, and intensity increases, and does not get damp not spontaneous combustion, not efflorescence, good drying effect.
4. in airtight drying shed, can guarantee effectively that the brown coal particle dries under the temperature and pressure of the best, steam consumption is little.
5. the brown coal material moisture in the oven dry is condensed into after water discharges, can recycle, and most of recovery of the latent heat of vaporization of steam carried out preheating and the oven dry of next drying shed brown coal material, and production cost is low, environmental protection.
6. adopt the drying shed of continuous connection mutually as the major equipment of oven dry, the drying shed technical parameter is low, and equipment manufacturing cost is low, and is easy to maximize, and heavy industrialization uses program simple.
7. oven dry/low-temperature cracking process of the present utility model and equipment thereof are equally applicable to the drying processing of unclassified stores (as vegetables and fruits, timber etc.).
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes a part of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings: Fig. 1 is the structural representation (arrow is the steam flow direction among the figure) of the utility model oven dry/low-temperature pyrolysis equipment.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Brown coal oven dry/low-temperature pyrolysis the equipment of a kind of steam heat conduction as shown in Figure 1, this equipment comprise the drying shed 1 that continues connection more than two mutually ... N is provided with heating unit 3 and condensate drain outlet 4 in each drying shed.Described heating unit 3 is device or the outside device to drying shed heat conduction of generation thermal source, as places the electric heater unit in the drying shed, or by the device of pipeline with superheated vapour, thermal oil, the heat conduction of cigarette vapour hot blast; Described condensate drain outlet 4 connects a water discharge valve and is arranged on the drying shed bottom.Each drying shed feeds steam by inlet pipe 11, and by the inlet pipe 21 of the next drying shed 2 of escape pipe 12 connections, the escape pipe 22 of drying shed 2 connects the inlet pipe of follow-up drying shed, is communicated with follow-up drying shed N by that analogy.Escape pipe 12 and 21 of inlet pipe in adjacent connection are provided with automatic air valve 6.
Now adopt the brown coal oven dry/low-temperature pyrolysis equipment of the utility model steam heat conduction that the brown coal material is dried/low-temperature pyrolysis, its step is as follows:
Step 1, the brown coal material is prepared
Put into the drying shed 1 that continues connection more than two mutually waiting to dry brown coal 5 ... N is also airtight.The charging method of waiting to dry brown coal 5 is beneficial to be heated evenly and is as the criterion, and can be truck, charging basket, hopper or other charging method.
Feed steam for one of them drying shed, the drying shed that present embodiment feeds steam is first drying shed 1, be full of steam and reach predetermined vapor pressure that (vapor pressure is more high until this first drying shed 1, its vapour density is more big, thermal conductivity is more high, drying time is more short, but corresponding drying shed technical parameter requires more high) after, stop to feed steam, and begin to start the steam heating that the heating unit 3 in this first drying shed 1 is given 1 li of this first drying shed, heated steam is through the condensation heat release, and heat exchange patterns such as convection current are dried to waiting to dry brown coal 5 heat passage.
Vapor temperature in step 2 raises and surpasses the burning-point of brown coal, prolongs heat-up time, to realize that brown coal are carried out low-temperature pyrolysis.
When the overvoltage steam that the drying shed that the utility model is positioned at upstream drying shed on reclaiming it enters carries out preheating and oven dry, a last drying shed of finishing oven dry can cool off simultaneously, discharging and charging, the rest may be inferred together, to bring into play the usefulness of each drying shed maximum.
