Description
Technical field
The utility model relates to a kind of sludge drying system, especially a kind of sludge superheated vapor drying system of two-stage paddle dryer.
Background technology
At present, analysis-by-synthesis sludge treatment and disposal technology system difficulty in actual applications, the water ratio of being not difficult to find out mud is crucial influence factor.Show through domestic and international application is actual, concentrate and after dewatering process handled, the water ratio of mud can not reach below 70% through traditional.So, reach the deep dehydration of mud, both economical method is to use heated drying technology commonly used in the chemical industry operation, the principle of heated drying technology is exactly that warm air after utilizing the dehydration of steam indirect heat exchange or utilizing heating carries out the convection drying dehydration to mud.
Mainly there is following shortcoming in these drying techniques:
Owing to adopt the steam indirect heat exchange, need equipment that very big heat interchanging area is arranged, and the thermal efficiency ratio of indirect heat exchange is lower, cause bigger energy consumption;
Owing to adopt the warm air after the heating that mud is carried out the mummification dehydration, allow the moisture in the mud reach the evaporating point dehydration, need a large amount of warm airs like this, cause operating environment poor, thermo-efficiency scatters and disappears more, and efficient is not high.
The lectotype selection of these technologies is bigger, causes the raising of facility investment, the raising of running cost, the increasing of maintenance capacity.
The utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of thermo-efficiency height, energy consumption is low, environmental pollution is little, cost is low sludge superheated vapor drying system of two-stage paddle dryer are provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of sludge superheated vapor drying system of two-stage paddle dryer, comprise one-level blade dryer and secondary blade dryer, sludge pump is connected by the opening for feed of pipeline with the one-level blade dryer, the discharge port of one-level blade dryer links to each other with the opening for feed of secondary blade dryer, and the discharge port of secondary blade dryer links to each other with the inlet of sludge incinerating boiler.
The air outlet of described one-level blade dryer is connected with sludge incinerating boiler with washing tower, induced draft fan A successively by pipeline.
The air outlet of described secondary blade dryer is connected with tornado dust collector, and tornado dust collector are connected with the blast inlet of secondary blade dryer and the blast inlet of one-level blade dryer respectively through induced draft fan B.
The vapour outlet of described sludge incinerating boiler is connected with the blast inlet of secondary blade dryer, and the tail gas outlet of sludge incinerating boiler is connected with chimney with tail gas washing tower, sack cleaner, induced draft fan C successively by pipeline.
Described one-level blade dryer condensation-water drain is connected with waste disposal plant through the washing knockout tower.
The condensation-water drain of described secondary blade dryer is connected with sludge incinerating boiler.
The utlity model has following characteristics:
1. total system adopts two-stage paddle dryer.Whole process system dried finished products mud granule enters sludge incinerating boiler and burns, and the steam of generation is introduced into the secondary blade dryer and carries out indirect heat exchange, and mud is dried.And the steam that the mud of secondary blade dryer inside produces through super-dry carries out dedusting by tornado dust collector and is pumped by induced draft fan then and got back to the secondary blade dryer, the drying of secondary blade dryer has formed closed internal recycle like this, through drying after a while, this circulation forms superheated vapour, secondary blade dryer inside just becomes superheat steam drying like this, and drying efficiency improves greatly.
2. the unnecessary superheated vapour that is formed by secondary blade dryer internal recycle enters the one-level blade dryer mud is dried, and is indirect heat exchange.The thermal source of one-level blade dryer has just saved like this, and directly the superheated vapour that is produced by dehumidification system own is dried.
3. adopt superheated vapour as drying medium.Compare with traditional warm air drying, as drying medium, the waste gas that drying machine is got rid of all is steam to this drying with water vapor, utilizes the latent heat that the method for condensation can recovered steam to be used again, and the consumption of drying medium obviously reduces, so unit heat consumption is low.
4. the air-out of one-level blade dryer washes away the free-water in the hot blast through the washing of washing tower, and the hot blast after the washing enters the mud boiler through the compression of induced draft fan, and the burning warm air that mud granule is used is provided.The moisture that carries of one-level blade dryer and secondary blade dryer is that natural air enters drying machine the steam that dried material in the drying machine produces is taken away, carry moisture and return to sludge incinerating boiler after via spray column, dedusting pressurization and burn, produce steam as combustion air.
Like this, whole dehumidification system not only material has been realized " zero release ", carry out perfect combustion because mud granule can enter sludge incinerating boiler, and the treatment measures such as landfill that need not enter next step is avoided secondary pollution; And the dry needed thermal source of heat energy system enters sludge incinerating boiler by the mud granule that self produces fully and carries out perfect combustion and provide; And hot-air system also realized " zero pollute ", because process air has been realized internal recycle, entered sludge incinerating boiler again fully by the air of the band dust of induced draft fan discharging.So being one, this technology is different from traditional sludge heat energy drying fully, but a kind of brand-new high-level efficiency, zero release, zero sludge treating system that pollutes.
The utility model no longer adopts conventional steam indirect heat exchange drying and heating back air to carry out drying technically, but the superheated vapour from generation carries out drying in the technology drying process of utilization own, and drying process has high thermo-efficiency in essence like this.The superheated vapour that self produces that utilizes of dehumidification system carries out drying, and thermal source adopts dried mud granule burning to provide, and unnecessary superheated vapour can provide all the other equipment utilizations of factory or life to utilize.To traditional mud oven dry having carried out transformation in essence.
The utility model is because of high-level efficiency, so lectotype selection is little, facility investment is few, and floor space reduces; Energy conservation, heat energy self system provides; Non-exhaust emission; Pollution-free, do not produce biosolid waste.
