Description
Technical Field
The invention relates to the field of waste gas emission treatment, in particular to a waste gas emission pipe with a rainproof function.
Background
The waste gas purification (Flue gas purification) mainly aims at the treatment of industrial waste gas such as dust particles, smoke dust, peculiar smell gas and toxic and harmful gas generated in industrial sites. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification and the like. The stack is the exhaust of the purification system. Because the purified gas still contains a certain concentration of pollutants, the pollutants are diffused and diluted in the atmosphere after being discharged through a chimney, and finally settle to the ground. In order to ensure that the ground pollutant concentration does not exceed the ambient air quality compliance standard, the chimney must have a certain height. In addition, in order to ensure that the exhaust gas purification system can operate normally, necessary auxiliary equipment is often required to be added to the purification system according to different purification treatment objects.
The conventional waste gas flows out from the side surface of the chimney pipe, the treated gas is blocked by the rain-proof cap at the upper part in the rising process, the distance from the umbrella cap to the wind pipe orifice is not well controlled, the wind resistance is low, the wind outlet is influenced, and the rain-proof effect is not good. In addition, there is also a ventilation pipe without umbrella cap, but the inside of the ventilation pipe is required to be provided with a water receiving funnel, and the diameter of the water receiving funnel cannot be smaller than that of the ventilation pipeline, so that larger wind resistance exists, ventilation and exhaust are not smooth, and larger kinetic energy loss is caused. Meanwhile, the prior patent publication No. CN104482556A discloses a ventilating duct air outlet rainproof device, the upper bent pipe and the lower bent pipe are connected through a flange, a rainwater drainage pipe is arranged on the right side of the lower half part of the upper bent pipe, a rainwater baffle is arranged above the rainwater drainage pipe, and the height of the rainwater baffle is not more than 60mm and not less than 40mm, so that exhaust gas exhausted from the ventilating duct in a room can be directly discharged to the high altitude, the environment is prevented from being polluted, meanwhile, the rainproof effect is good, the wind resistance is truly reduced to the minimum, and the energy conservation is facilitated. The technical scheme of this patent adopts the return bend as rain-proof measure, but is not enough in that adopt the rainwater baffle, if the baffle is too little to reach the water proof effect, the too big separation pipeline of baffle is discharged, causes the energy consumption higher moreover, and this patent does not take the drainage measure to the upper wall of return bend simultaneously, and the rainwater still can flow into inside the ventilation pipe through the return bend upper wall, therefore still has certain defect and not enough needs to improve.
Comprehensive above prior art, exhaust pipe open discharges and does benefit to the diffusion of waste gas, is favorable to the environmental protection, but open discharges rain-proof problem still not obtain good solution, and exhaust pipe open discharges rain-proof problem need to be solved urgently.
