Description
Technical field
The utility model relates to the automatic descaling apparatus of lime industry kiln heat exchanger applied.
Background technology
With low heating value coal gas be lime (or dolomite) shaft furnace of fuel because delivery temperature is higher, it is big directly to discharge heat loss, the energy consumption height.Therefore generally adopt the mode of preheated air, coal gas to reclaim fume afterheat.But because this high-temp waste gas (generally greater than 300 ℃) has dust, steam and sour gas, when entering heat exchanger, can form calcified material hard film dirt in heat exchanger tube inlet end gradually, obstruction waste gas passes through, need artificial periodic cleaning dirt, not only influence the equipment operate as normal, shorten service life of equipment, and increased labor intensity of operating personnel.Therefore need a kind of automatic descaling apparatus that can clear up the heat exchanger dirt automatically.
Summary of the invention
The purpose of this utility model provides the automatic descaling apparatus of a kind of labor cleaning of need not, the on-line automatic cleaning heat exchanger dirt of energy, and this device can guarantee that equipment moves continuously, prolongs service life of equipment, can also reduce labor strength.
For achieving the above object, the utility model adopts following technical scheme to realize:
The automatic descaling apparatus that is used for heat exchanger, this device comprise pulse control instrument, divide gas bag, fixed mount, impulse electromagnetic valve, radiating tube, blowing part, divide gas bag to be installed on the fixed mount, are welded on the heat exchanger outside; On minute gas bag top impulse electromagnetic valve is installed, the winding-up blanking time and the cycle of impulse electromagnetic valve are set by pulse control instrument, can regulate arbitrarily according to the fouling situation; The port of export at impulse electromagnetic valve connects radiating tube, and radiating tube connects blowing part, and blowing part is installed in the arrival end of heat exchanger tube and keeps certain distance.
The corresponding blowing part of each impulse electromagnetic valve or corresponding a plurality of blowing part.
Described blowing part is made up of the winding-up person in charge, winding-up arm, nozzle, and winding-up is responsible for and is provided with several winding-up arms, and it is corresponding with the heat exchange mouth of pipe that the arm of jetting is provided with nozzle.
Described winding-up can be arranged a row or multi-row winding-up arm on being responsible for, and the quantity of winding-up arm and nozzle can be adjusted arbitrarily according to the quantity of heat exchanger heat-exchanging tube.
The utility model has the advantages that: solved present lime shaft kiln heat exchanger and formed calcified material hard film dirt, hindered waste gas and pass through, needed artificial periodic cleaning dirt, the problem that influence is produced in heat exchanger tube inlet end.Reached and need not the labor cleaning, purpose that can online automatic desludging has reduced labor strength, has prolonged service life of equipment.
