Abstract
The invention relates to an air volume uniform distribution system for insulators of a wet type electric precipitator. The air volume uniform distribution system comprises the wet type electric precipitator, a sealed air pipeline and the insulators. The sealed air pipeline comprises a plurality of branch pipe openings, wherein each branch pipe opening exactly faces the corresponding insulator, and a manual adjustment butterfly valve is arranged in each branch pipe opening. The air volume uniform distribution system has the advantages that each manual adjustment butterfly valve and a matched pipe are set for the corresponding insulator, the pipes are led to the positions above the insulators one by one, the volume of air which is led to the sealed air pipes can be adjusted to remove the pressure of smoke, after adjustment is accomplished, adjustment does not need to be conducted again in the equipment follow-up operation process only if the equipment performance is stable, the system is simple, and the practicability is high. The system comprises the manual adjustment butterfly valves, miniature pressure gauges and the auxiliary pipes, and is simple and reliable, follow-up operation does not need to be conducted basically after adjustment is accomplished for the first time, and the air pressure at the positions of the insulators can be monitored so as to preferably ensure stable and safe operation of the wet type electric precipitator.
Description
Technical field
Patent of the present invention relates to the equal match system of air quantity, particularly relates to the equal match system of a kind of wet electrical dust precipitator insulator air quantity.
Background technology
Many coal-burning power plants install wet electrical dust precipitator additional in order to efficient cooperation-removal fine particle after desulfuration absorbing tower.Wet electrical dust precipitator runs under being generally in barotropic state.Leaking from insulator for preventing wet flue gas causes condense creepage and wet flue gas condensation ponding of insulator to cause insulator chamber corrode, generally arranges enclosed air system (part is by sealing air heating) and, in order to overcome the malleation of flue gas, avoids above-mentioned situation to occur.Because wet electrical dust precipitator insulator number is more, at present, wet electrical dust precipitator top insulator chamber arranges enclosed air system, generally introduce in the one-sided usual passage of insulator chamber of separate unit wet electrical dust precipitator by single pipe, rely on the flowing wind be full of in whole insulator chamber to overcome malleation, SI semi-insulation place's flow will certainly be caused and pressure is less than normal does not have due effect, cause allocation of the amount of air extremely uneven, the insulator air quantity that distance sealing air pipeline introduces point near is larger, the insulator air quantity that distance introduces point far away is less, does not have due effect.
Summary of the invention
The object of the invention is to overcome prior art deficiency, provide a kind of rational in infrastructure, the allocation of the amount of air that can realize each insulator place of wet electrical dust precipitator is even, the equal match system of wet electrical dust precipitator insulator air quantity that pressure can be monitored.
For achieving the above object, present invention employs following technical scheme:
The equal match system of wet electrical dust precipitator insulator air quantity, comprises wet electrical dust precipitator, sealing air pipeline and insulator, and described sealing air pipeline is provided with the multiple points of mouths of pipe, and each point of mouth of pipe is just to an insulator, and the described point of mouth of pipe is provided with manual adjustments butterfly valve.
As preferably: point mouth of pipe is also provided with micro-pressure gauge.
As preferably: point mouth of pipe is right against the top of insulator.
The invention has the beneficial effects as follows:
Native system arranges manual adjustments butterfly valve and ducts to each insulator, pipeline is caused one by one the top of each insulator, the air quantity that adjustable every root introduces sealing air pipe overcomes the pressure of flue gas, after adjustment completes, as long as equipment performance is stable just without the need to regulating again in equipment follow-up operation process, system is simple, practical.
Native system is made up of several manual adjustments butterfly valve valves, micro-pressure gauge and associated pings, simple and reliable, regulate rear basic without the need to carrying out subsequent operation first, and the blast at insulator place can have been monitored, better ensured that the stability and safety of wet electrical dust precipitator is run.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Description of reference numerals: wet electrical dust precipitator 1, sealing air pipeline 2, insulator 3, manual adjustments butterfly valve 4, micro-pressure gauge 5, point mouth of pipe 6.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.The explanation of following embodiment just understands the present invention for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
The equal match system of wet electrical dust precipitator insulator air quantity of the present embodiment, comprise wet electrical dust precipitator 1, sealing air pipeline 2 and insulator 3, described sealing air pipeline 2 is provided with the multiple points of mouths of pipe 6, and each point of mouth of pipe 6 is just to an insulator 3, and the described point of mouth of pipe 6 is provided with manual adjustments butterfly valve 4.Divide on the mouth of pipe 6 and be also provided with micro-pressure gauge 5.The mouth of pipe 6 is divided to be right against the top of insulator 3.
As shown in Figure 1, before wet electrical dust precipitator 1 power initiation, seal fan is opened, calculate the air quantity Q at each insulator 3 top, utilize apparatus for measuring air quantity to test the sealing air quantity at each insulator 3 top, manually regulating butterfly valve 4 regulates air quantity to its value at insulator 3 top to be about Q one by one.The aperture regulating rear manual regulating butterfly valve 4 no longer changes, and runs wet electrical dust precipitator.The pressure of each insulator 3 top seal wind can be monitored the moment by micro-pressure gauge 5, when pressure is less, e-quipment and pipe in timely check system.When judging that seal fan performance changes to some extent, manual adjustments butterfly valve 4 can be carried out again and regulate until each insulator 3 top allocation of the amount of air is even.
This system comprises manual adjustments butterfly valve 4, micro-pressure gauge 5 and associated ping.Sealing air pipeline 2 branch path is caused wet electrical dust precipitator insulator 3 top one by one, when using first, the manually sealing air quantity at regulating butterfly valve 4 uniform distribution each insulator 3 top, substantially regulating without the need to carrying out other again when normal operation, can effectively prevent the creepage and flue gas of the condensation of insulator 3 to external leakage.Each branch road divides the mouth of pipe 6 to arrange micro-pressure gauge 5, can monitor the pressure at each insulator 3 place, ensures that this place's blast can overcome the flue gas pressures of wet electrical dust precipitator 1 inside.According to the performance of equipment and pipeline in pressure change judgement system.
This device is applied on Leqing power plant No. 4 units.
