Description

The air cooling tubes condenser spray equipment

Technical field

The utility model relates to a kind of spray equipment, is specifically related to a kind of air cooling tubes condenser spray equipment that is applicable to thermal power plant or petrochemical industry.

Background technology

At present, country actively implements and economizes on resources and protect the environment fundamental state policy, build lowly drop into, high production, low consumption, few discharging can circulate, continuable national economic system and resource-conserving and environment-friendly society.And in the industrial production of industries such as heat power station and petrochemical industry, the condenser of Air-cooled Unit is important heat dissipation equipment.The condenser of thermal power plant Air-cooled Unit exists heat exchange efficiency to descend, cause vacuum to descend when rising of environment temperatures such as summer and working conditions change, and the load band does not get on, and problems such as back pressure rising have a strong impact on power benefit and safety in production.The tradition solution is to transform to increase Air-cooled Unit cooling system heat exchange area, but it is big, long in time limit to do investment like this, and when environment temperature was low, particularly winter, utilization rate was very low, caused the idle of part air cooling apparatus.

The utility model content

The utility model is in order to solve weak point of the prior art, provide a kind of air cooling tubes condenser spray equipment, this device can solve condenser in Air-cooled Unit effectively in environment temperature during higher and operating condition variation, the adverse effect that heat exchanging efficient causes.

For solving the problems of the technologies described above, air cooling tubes condenser spray equipment of the present utility model comprises nozzle, pressure water source and the pipeline that both are connected, and described pipeline is made up of spray main and spray arm, a spray tube side-by-side is connected on the spray main, and nozzle is installed on the spray arm.

Described pressure water source comprises water tank and suction pump, and the spray main draws water to hold and is connected with water tank by suction pump.

On drawing water the spray main of holding, suction pump is provided with filter and manually-operated gate.

All be connected with water pressure gauge on the described every spray arm.

Described every spray arm front end is equipped with flow control valve.

On the spray main of suction pump water side, be provided with filter, drain valve, non-return valve and water pressure gauge successively.

Adopt said structure, will spray arm and be deep into air cooling tubes condenser inside, the nozzle direction is aimed at the heat exchange unit surface, sprays heat exchange by pressure water source to its water supply; By the conveying that the pump lift that draws water realizes that water is hoisted by lower, adapt to air cooling tubes condenser tens meters duty above ground level is installed; The twice filter can filter out minute impurities in the water, prevents that the impurity plug nozzle from influencing heat exchange efficiency; On every spray arm, water pressure gauge is set, can monitors hydraulic pressure in real time, and regulate the flow control valve that is installed in the arm front end according to the needs such as variation of flow, pressure, thermic load; The utility model is simple in structure, investment is little, the duration is short, heat exchange efficiency is high, solved air cooling tubes condenser descends, causes vacuum to descend because of environment temperature and working conditions change cause heat exchange efficiency, the load band does not get on, problems such as back pressure rising, practical, be easy to apply.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, air cooling tubes condenser spray equipment of the present utility model comprises nozzle 1, pressure water source and the pipeline that both are communicated with, and described pipeline is made up of spray main 2 and spray arm 3, spray arm 3 is connected on the spray main 2 side by side, and nozzle 1 is installed on the spray arm 3.Pressure water source comprises water tank 4 and suction pump 5, and spray main 2 draws water to hold and is connected with water tank 4, and suction pump 5 is installed on the sprinkler main 2, and suction pump 5 is connected with gauge tap 7 by lead 6.Be provided with filter 8 and manually-operated gate 13 on suction pump 5 draws water the spray main 2 of end, manually-operated gate 13 can end and circulates spray main 2.All be connected with water pressure gauge 9 on the end of every spray arm 3.Every spray arm 3 front ends are provided with flow control valve 10.Be provided with filter 11, drain valve 12, non-return valve 15 and water pressure gauge 14 on the spray main 2 of suction pump 5 water sides successively.The delivery port of drain valve 12 can be connected with water tank 4 by water pipe.Non-return valve 15 can prevent to spray main 2 water and be back in the water tank 4, occurs vaccuum phenomenon when suction pump 5 is worked once more and have influence on.Certainly, suction pump is directly groundwater abstraction or river also, needn't use water tank 4.

After gauge tap 7 started, the water in the suction pump 5 work extraction water tanks 4 was through filter 8; Be circulated to filter 11 again; The water that does not have impurity is by the flow control valve 10 on the spray arm 3 that connects side by side on the spray main 2, spray to the radiator of need spray by the nozzle 1 that is installed in side by side on the spray arm 3 again, the water pressure gauge 9 that the terminal of spray arm 3 is installed, be used for monitoring in real time variation in water pressure, size adjustment flow control valve 10 according to water pressure gauge 9 is adjusted water spray, and the data that arrive of monitoring and statistics are adjusted update the system work thus.According to water pressure gauge 14 and the pressure differential that water pressure gauge 9 shows, suitably open drain valve 12, make excessive water be back to water tank 4 by drain valve 12.In addition, in nozzle 1 hydraulic back-pressure valve is housed, in order to the water ejection that prevents from not atomize when hydraulic pressure is not enough, when hydraulic pressure reached design load, water was with atomizing or the ejection of less spray grain pearl form.
