Abstract
The utility model relates to a kind of device promoting heat exchanger heat transfer effect, comprise energy storage canister, energy storage canister two ends are provided with inlet tube and outlet, inlet tube connects instrument air outlet, outlet connects scavenging conduit, uniform in the shape of a spiral purge nozzle on scavenging conduit, magnetic valve is equipped with outlet, magnetic valve connect hours relay.System meter air sends into energy storage canister from inlet tube, as power source and the blowing medium of this blow device, by the effect of the time relay to magnetic valve open degree and the control realization automatic blowing of the cycle of operation; Purge unit primarily of the purge nozzle composition be distributed on along helical form on scavenging conduit, instrument air is discharged by blow valve port, according to momentum theory, utilizes the active force purging air-flow to drive scavenging conduit automatic rotation, realizes the omnibearing purging of equipment.The impact of the utility model device on equipment tubing is less, is beneficial to the long-period stable operation of equipment.
Description
Technical field
The utility model relates to the inner dust arrester of heat exchanger.
Background technology
In Chemical Manufacture the heat exchanger of boiler, blowing-out gas waste heat boiler superheater, urea final cooler operation in often occur that dust impurities sticks to the heating surface of heat exchanger, heat exchanger thermal resistance is caused to raise, heat transfer efficiency reduces, the normal heat transfer effect of the equipment that affects, brings adverse effect to the stable operation of system.The dedusting technology such as dust collection by sound wave that existing heat exchanger adopts, shake reach dedusting long-play after often cause equipment material tired, easily there is fracture in interface, telescopic dust arrester using method is loaded down with trivial details, and purge and easily leave dead angle.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of device promoting heat exchanger heat transfer effect, and this device realizes by sweep module the purging adhering to magazine in equipment, ensures heat exchanger heat transfer efficiency.
For solving above technical problem, the utility model adopt technical scheme be:
A kind of device promoting heat exchanger heat transfer effect, comprise energy storage canister, energy storage canister two ends are provided with inlet tube and outlet, inlet tube connects instrument air outlet, outlet connects scavenging conduit, uniform in the shape of a spiral purge nozzle on scavenging conduit, magnetic valve is equipped with outlet, magnetic valve connect hours relay.
During work, system meter air sends into energy storage canister from inlet tube, as power source and the blowing medium of this blow device; Energy storage canister outlet is connected with purging unit by magnetic valve, by the effect of the time relay to magnetic valve open degree and the control realization automatic blowing of the cycle of operation; Purge unit primarily of the purge nozzle composition be distributed on along helical form on scavenging conduit, instrument air is discharged by blow valve port, according to momentum theory, utilizes the active force purging air-flow to drive scavenging conduit automatic rotation, realizes the omnibearing purging of equipment.
The impact of automatic rotation sweep module on equipment tubing that the utility model adopts is less, and realizes 360 degree of comprehensive purgings, is beneficial to the long-period stable operation of equipment.
Accompanying drawing explanation
Fig. 1 is connection diagram of the present utility model.
Fig. 2 is the structural representation of scavenging conduit and purge nozzle.
In figure, 1-energy storage canister, 2-inlet tube, 3-outlet, 4-scavenging conduit, 5-purge nozzle, 6-magnetic valve, the 7-time relay, 8-rolling bearing.
Detailed description of the invention
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model.
As shown in Figure 1, a kind of device promoting heat exchanger heat transfer effect described in the utility model, comprises energy storage canister 1,
Energy storage canister 1 two ends are provided with inlet tube 2 and outlet 3, and inlet tube 2 connects instrument air outlet, and outlet 3 connects scavenging conduit 4.Energy storage canister 1 import caliber is less than outlet caliber.Energy storage canister 1 import caliber is less, avoids this blow device use gas to cause larger fluctuation to system; It is comparatively large that energy storage canister 1 exports caliber, adapts to the needs that large discharge purges.
System meter air sends into energy storage canister 1 from inlet tube 2, as power source and the blowing medium of this blow device.Blow device power source, except system meter air described in the utility model, also can adopt other media according to actual conditions, such as inert gas, system gas medium etc.
Uniform in the shape of a spiral purge nozzle 5 on scavenging conduit 4, scavenging conduit 4 is cylindrical, is arranged on rolling bearing 8, can take different structural forms and size in practical application according to concrete apparatus-form.The angle of the mutual angle of purge nozzle 5, spacing and purge nozzle self can adopt adjustable, and the change according to equipment operating condition adjusts flexibly.Purge nozzle 5 and scavenging conduit 4 are designed to certain angle, utilize the active force purging air-flow to drive scavenging conduit 4 automatic rotation, realize the omnibearing purging of equipment.
Magnetic valve 6 outlet 3 is equipped with, magnetic valve 6 connect hours relay 7.The signal of telecommunication passes through open degree and the cycle of operation control of the time relay 7 pairs of magnetic valves 6, and concrete controling parameters carries out different settings according to the different operating mode of equipment.
The claimed scope of the utility model is not limited to above detailed description of the invention; to those skilled in the art; the utility model can have various deformation and change, all in design of the present utility model and any amendment, the improvement done within principle be equal to replacement and all should be included within protection domain of the present utility model.
