Description

The alumina clinker heat sink
Technical field
The present invention relates to a kind of alumina clinker heat sink, belong to grog cooling technique equipment field in the alumina producing sintering circuit.
Background technology
At present, alumina clinker heat sink of the prior art is that the slight negative pressure that the outlet of trickle and cooler produces outside the cooler cylindrical shell will be lowered the temperature to alumina clinker in the air suction cooler, because of cooling-down effect poor, usually the alumina clinker temperature can be reduced to 320 ℃ ± 60 ℃ by 1000 ℃, but clinker temperature is still higher, do not reach production requirement below 230 ℃, make on the one hand and enter stripping of next procedure grog and settlement separate alumina clinker temperature drift, directly cause aluminum oxide and the loss of sodium oxide secondary reaction in the grog to increase; Clinker temperature is higher on the other hand, and the heat of directly taking away can't reclaim, and calorific loss is bigger.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of alumina clinker heat sink is provided, this device can make the alumina clinker cooling, can reclaim the part heat that grog is taken away again, the alumina clinker temperature is lower than below 230 ℃, greatly reduce grog in stripping and aluminum oxide and the loss of sodium oxide secondary reaction when settlement separate, to overcome deficiencies such as alumina clinker temperature drift, calorific loss that prior art exists are bigger.
The present invention constitutes like this: it comprises pipeline 1, electronic reverse flow valve 2, PLC control unit 3, microcomputer 4, infrared thermometer 5, gate valve 6, impeller pump 7, electronic main valve 8, under meter 9, tensimeter 10, nozzle 11, cooler 12, impeller pump 7 is installed on pipeline 1, electronic reverse flow valve 2 is connected impeller pump 7 and advances, exit end, gate valve 6 and electronic main valve 8 are connected to impeller pump 7 and advance, on the outlet conduit, nozzle 11 is connected pipeline 1 termination and stretches into cooler 12 outlet the insides, under meter 9, tensimeter 10 is installed on the pipeline 1 between electronic main valve 8 and the nozzle 11, and outside line temperature measurer 5 is installed in cooler 12 exits; Under meter 9, tensimeter 10, outside line temperature measurer 5 are electrically connected with PLC control unit 3, and PLC control unit 3 is electrically connected with microcomputer 4.
Electronic reverse flow valve 2 is electrically connected with PLC control unit 3.
Electronic main valve 8 is electrically connected with PLC control unit 3.
During work, under meter 9, tensimeter 10, infrared thermometer 5 detects numerical value and regulates control by PLC control unit 3 and 4 pairs of electronic reverse flow valves 2 of microcomputer, electronic main valve 8 apertures, the alumina clinker temperature and the electronic main valve 8 apertures interlocking of 12 outlets of infrared thermometer 5 monitoring coolers, cooler 12 stops and electronic reverse flow valve 2, electronic main valve 8 apertures interlocking, tensimeter 10 monitoring pressure data and electronic reverse flow valve 2 apertures interlocking.
The present invention lowers the temperature to alumina clinker by spray cyclic regeneration water, can reclaim the part heat that grog is taken away, can rapidly and efficiently lower the temperature again, the alumina clinker temperature is lower than below 230 ℃, greatly reduce grog in stripping and aluminum oxide and the loss of sodium oxide secondary reaction when settlement separate; And can concentrate recycling to waste gas from the opening for feed of cooler.
Compared with prior art, the present invention has advantages such as cooling-down effect is remarkable, the clinker temperature controllability is strong, the grog heat can reclaim, use the present invention can guarantee that the alumina clinker cooling meets production requirement, greatly reduce grog and lose at stripping aluminum oxide and sodium oxide secondary reaction when settlement separate.
