This product has achieved the following technical effects relative to the prior art.
1. In this product, a sealed collection system and a tail gas de-white treatment system are set up in the phosphoric acid plant for the collection and de-white of the spent vapor of the rotary filter, the sealed collection system includes an air collection hood and an extraction tube, the air collection hood is set between the washing area and the slag discharge area of the rotary filter to form a sealed space, which covers the fluorinated spent vapor between the washing area of the rotary filter in the sealed space, changing the traditional free The fluorine containing vapor is sent to the exhaust gas de-white treatment system through the extraction port and the extraction pipe, which can significantly reduce the pollution to the atmosphere and will not affect the appearance of the factory environment after the flue gas is de-white.
2. In this product, the extraction pipe is divided into several extraction stubs and the extraction main set in the middle of the rotary filter, and the extraction stubs are connected to the collection hood respectively, so that the spent vapor generated from each washing area can be collected and sent to the extraction main for unified collection, while the extraction port and the extraction stub, and the extraction stub and the extraction main are connected with flanges, which greatly facilitates the maintenance and replacement at a later stage.
3. The combination of rigid plastic panel and gas cover skeleton can keep its shape unchanged and will not expand or collapse with the gas, which can avoid the situation that the soft plastic and the turntable filter connection is easy to be tightly closed and lead to leakage, or the collection space is too large with the expansion of gas, which makes it difficult to collect when pumping, or the area The problem of incomplete recovery of water vapor containing fluorine.
4. In this product, the filter exhaust gas de-white treatment system includes a horizontal scrubber, a vapor-liquid separation tower and a washing water circulation and cooling system; through the induced draft fan, the spent vapor collected by the extraction director is sent into the horizontal scrubber, and through the vacuum pump, the spent vapor generated in each washing area of the turntable filter is sent into the horizontal scrubber, and under the action of the washing water supplied by the washing water circulation and cooling system, the fluorine-containing spent vapor is cooled down and washed, and then the washed fluorine-containing vapor is sent to the horizontal scrubber. After washing, the fluorinated vapor is sent to the vapor-liquid separation tower for separation, and the separated flue gas is directly discharged into the atmosphere. The separated washing water is sent back to the water circulation cooling system from the vapor-liquid separation tower for cooling, so that it can be sent to the horizontal scrubber again.
5. The horizontal scrubber in this product is equipped with a washing lance for easy unblocking, through which the contact area with the spent steam can be increased to improve the effect of purification and de-whiting.
6. The input end of the horizontal scrubber in this product is set on the ground at an upward slope. When the scrubber is installed, it is tilted from back to front, which is conducive to the flow of washing water to the vapor-liquid separation tower on the one hand, and can prevent backflow on the other hand.
7,  the seal collection system, horizontal scrubber and vapor-liquid separation tower in this product is located in the factory floor is higher than the washing water circulation cooling system, horizontal scrubber and vapor-liquid separation tower and washing water circulation cooling system to form a height difference, the use of floor height difference washing water can flow directly back into the circulating water system, into the circulating water cooling tower cooling, without the need to set additional circulation pump to pump the washing water out of the vapor-liquid separation tower.

The purpose of this product is to solve the above technical problems, provide a spent vapor de-whitening device, set up a sealed collection system and exhaust gas de-whitening treatment system, effective collection of spent vapor generated by the turntable filter in the phosphoric acid plant, while the collected exhaust gas will be de-whitened to avoid direct discharge into the atmosphere affecting the environment and leaving an unattractive impact on the appearance of the view.
In order to achieve the above purpose, the product provides the following solution: the product provides a spent vapor de-white device, which is used to deal with the spent vapor de-white of the rotary plate filter in the phosphoric acid plant, including a sealed collection system and a tail gas de-white treatment system; the sealed collection system includes an air collection hood and an extraction tube, the air collection hood is set between each washing area and the slag discharge area of the rotary plate filter, an extraction port is opened at the top of the air collection hood, and the extraction port is connected to the tail gas de-white treatment system through an extraction tube. The air collection hood is provided with an air extraction port at the top of the air collection hood, and the air extraction port is connected to the exhaust gas whitening treatment system through an air extraction pipe.
The extraction pipe includes an extraction branch pipe and an extraction main pipe installed in the middle of the turntable filter, and the extraction port is connected to the extraction main pipe through the extraction branch pipe.
The pumping port is connected to the pumping main through the pumping stub by a flange.
The extraction branch pipe is connected to the extraction main pipe by a flange.
The air receiver hood includes a hood skeleton and a plastic panel set on the hood skeleton, which is rooted on the ground outside the inner stationary part and the outer ring of the turntable filter.
The plastic panel is made of reinforced polypropylene sheet or polyethylene plastic material.
The filter exhaust gas de-white treatment system includes a horizontal scrubber, a vapor-liquid separation tower and a scrubber water circulation cooling system; the input end of the horizontal scrubber is connected to the extraction main through the induced draft fan and connected to the turntable filter through the vacuum pump, and the output end of the horizontal scrubber is connected to the vapor-liquid separation tower; the input end of the scrubber water circulation cooling system is connected to the vapor-liquid separation tower, and the output end of the scrubber water circulation cooling system is connected to the horizontal scrubber. The input end of the scrubber water circulation cooling system is connected to the vapor-liquid separation tower, and the output end of the scrubber water circulation cooling system is connected to the horizontal scrubber.
The horizontal scrubber is equipped with a washing lance, and the horizontal scrubber is connected to the output of the washing water circulation and cooling system through the washing lance.
The input end of the horizontal scrubber is set on the ground at an upward angle.
The sealed collection system, the horizontal scrubber and the vapor-liquid separation tower are located on a plant floor above the scrubber water circulation cooling system.
