Background technology
In sludge carbonization disposal process, the biological carbonization temperature producing is higher, should carry out cooling could pack.The cooling existing problem of technology of charcoal mainly contains two at present: the one, and adopt single cooling medium---water---to carry out cooling, water consumption is larger, causes the waste of resource; The 2nd, the discharging of charcoal is to adopt manually gate valve or the discharging of electric brake plate valve, except not producing continuously, cause that material stock, cooling effectiveness are low, operating environment dirtier outside, also because of poorly sealed, in the easy access to plant of air in environment, easily under the condition of high temperature, there is explosion accident with micro-fuel gas wherein.
Summary of the invention
The purpose of this utility model is to provide a kind of for the cooling device of charcoal, high-temperature biological charcoal is carried out cooling in, required incinerator air heat can also be heated up, reduce the consumption of incinerator fuel; It is desired below 50 DEG C that the use of a small amount of cooling water can ensure that the temperature of charcoal drops to; The use of screw discharging machine, except improved this device tightness, reduced having entered, reduced the risk of explosion occurring of air, can also effectively prevent fuel gas excessive, the leakage that reduces charcoal, can keep the clean of operating environment.This device can be realized energy-saving and environmental protection, safety and operation reliably.
The technical scheme that realizes above-mentioned purpose is: high-temperature biological charcoal first carries out indirectly heat exchange with cooling medium 1---surrounding air---, carry out indirect heat exchange with cooling medium 2---water---again, finally in the time that the temperature of charcoal drops to below 50 DEG C, under the effect of screw discharging machine, discharge continuously through charcoal outlet.In the inlet tube side of charcoal, the adapter of material sensor and the adapter of oxygen detection instrument are housed respectively, for detection of discharging situation and the oxygen content of charcoal.The distributor being equipped with in device, except charcoal being distributed equably, is beneficial to carry out better outside heat exchange, can also protect well heat exchanger tube, reduce the impact of charcoal to it.Heat exchange airduct in device and heat exchanging water pipe all adopt triangle layout in upright arrangement, and the import and export of cooling air and cooling water all adopt the design of bottom in and top out.Middle and lower part outside device and bottom are respectively equipped with middle part temperature sensor and take over and temperature of lower sensor, are for mounting temperature sensor, to detect cooling air and the cooling effect of cooling water to charcoal.In the bottom of device, the top compressed air that is equipped with is taken over, and is for preventing that as because of long-term stall, " bridge formation " phenomenon occurs the charcoal having in bottom, can be before startup, and the charcoal of bottom is blown afloat, stirred, the mobility of raising charcoal with compressed air.Screw discharging machine is equipped with in bottom at device, on the basis that can ensure to draw off continuously charcoal, air can be completely cut off again outside device, reduce biological charing leakage, has improved the sealing of installing, the security of production, has also protected on-the-spot operating environment.
Because air-cooled heat exchange efficiency is lower than the heat exchange efficiency of water-cooled, be only difficult to make charcoal to reach the technological requirement following lower than 50 DEG C with air-cooled, therefore also will carry out again water-cooled after air-cooled.
The utility model is to be exported by charcoal, compressed air inlet, cooling water inlet, cooling air import, crust of the device, material sensor is taken over, charcoal import, oxygen detection instrument is taken over, cooling air outlet, middle part temperature sensor is taken over, coolant outlet, temperature of lower sensor is taken over, screw discharging machine composition, in device, distributor is also housed, cooling air heat exchanger tube and cooling water heat exchanger tube, cooling air import and cooling air outlet be the both sides outside device respectively, middle part temperature sensor adapter is equipped with respectively in middle and lower part outside device and bottom and temperature of lower sensor is taken over, at charcoal inlet side, the adapter of material sensor and the adapter of oxygen detection instrument are housed respectively, in the top compressed air inlet that is equipped with in bottom of device, in the bottom of device, on charcoal outlet, screw discharging machine is also housed.
Adopt the beneficial effect of technique scheme to be: 1, energy-conservation.The cooling medium of environment temperature, after---air---heating, is become to hot-air and passes into incinerator, can reduce the consumption of incinerator auxiliary fuel; By the cooling medium of environment temperature after---water---heating, can provide hot water service for employee's bathing or for society; The bottom of removal apparatus has outside a low power spiral discharging machine, and main equipment is without any drive apparatus, and electric load is little.2, safety.The charcoal import of this device, also be the gas outlet of fuel gas, outside chamber inner tube due to this device, communicate with carbonizing apparatus, and be the state of micro-negative pressure, therefore can be by high-temperature biological charcoal in this device, the a small amount of residual fuel gas producing is mouthful discharge from then on, has improved the safe operation coefficient of equipment; The bottom of device adopts screw discharging machine, has improved the tightness of this device, has reduced entering of air, has reduced the risk of explosion of this device.3, environmental protection.Micro-negative-pressure design outside the inner tube of chamber, can prevent the excessive of fuel gas effectively, has avoided the pollution of environment; Adopt screw discharging machine discharging, can reduce the leakage of charcoal, can keep the clean of operating environment.
