First, the gas collection hopper 11 serves as an initial collection component of the overall system, and its hopper design is effective to collect and direct flue gases from the calciner. The top of the gas collecting hopper 11 is connected with a flue gas outlet of the calciner through a gas-entraining pipe group 21, so that the flue gas can be guided into the gas collecting hopper 11 smoothly and efficiently. The bleed air pipe group 21 comprises a plurality of branch pipes so as to adapt to flue gas sources with different positions or different discharge amounts, thereby enhancing the flexibility and adaptability of the system, and meanwhile, the design of the turnover pipe group 22 needs to consider the flow and pressure of the flue gas, so that the flue gas can be transferred stably and without leakage.
The flue gas treatment barrel 12 is internally filled with treatment solvents which can chemically react with harmful substances in the flue gas, thereby achieving the purpose of purifying the flue gas.

The whole system of this embodiment is through steps such as gas collection, processing, white, promotion and absorption, effectively purifies the flue gas, and recycle heat energy simultaneously realizes the flue gas treatment of high-efficient environmental protection.
In one embodiment, referring to fig. 1, 2 and 3, based on what has been described in the above embodiments, for the specific implementation of the bleed air pipe stack 21 and the air collection hopper 11, this embodiment is designed as follows:
The air-entraining tube group 21 comprises a first air-entraining tube 31 and a second air-entraining tube 32, the first air-entraining tube 31 and the second air-entraining tube 32 are connected with the air collecting hopper 11, air inlet heads 33 are arranged at the tube ends of the first air-entraining tube 31 and the second air-entraining tube 32, regulating valves 34 are arranged on the tube bodies, a spray branch tube 37 is externally connected to the air inlet heads 33 of the second air-entraining tube 32, a three-way converging valve 35 is further arranged on the tube body of the first air-entraining tube 31, and the three-way converging valve 35 is connected with the second air-entraining tube 32 through a converging tube 36.
The first gas introduction tube 31 is designed to exclusively introduce flue gas having a low dust content. Such flue gases typically originate from certain specific locations of the calciner, such as the upper or tail portion of the furnace, where the particulate concentration is relatively low. The air inlet head 33 of the first air guiding pipe 31 adopts an optimized design so as to ensure that the flue gas can smoothly enter the air collecting hopper 11, and meanwhile, the air flow resistance is reduced. The control valve 34 on the pipe body allows the operator to adjust the flow of the flue gas according to the actual need to achieve more accurate control. The second gas-introducing pipe 32 is responsible for introducing flue gas with higher dust content. Such flue gases typically originate from the combustion zone of the calciner and contain a significant amount of particulate matter and fly ash. In order to reduce the risk of abrasion and clogging of subsequent treatment equipment by these particles, a spray manifold 37 is circumscribed to the inlet head 33 of the second gas conduit 32. The spray manifold 37 can spray a proper amount of water mist to moisten and agglomerate the particles in the flue gas so as to be more easily trapped and treated. Meanwhile, the addition of water mist can also reduce the temperature of the flue gas and improve the stability of subsequent treatment equipment.
On the body of the first air-inducing pipe 31, we also set a three-way junction valve 35, which is connected with the second air-inducing pipe 32 through a junction pipe 36, so as to realize interconnection and intercommunication between two pipelines. When necessary, the operator can open the three-way junction valve 35 to allow the fumes in the first and second air pipes 31 and 32 to mix. The purpose of design like this can be according to actual dust content and the processing demand of flue gas, adjusts the flue gas proportion in two pipelines in a flexible way to reach best treatment effect.

The inside of the hopper body of the gas-collecting hopper 11 is provided in particular with a filtering device consisting of a plurality of layers of filtering material, each layer of material being optimally selected for specific smoke components and particle sizes. The main function of the filtering device is to intercept and trap particulate matters, smoke dust and part of harmful substances in the smoke, so as to ensure that the smoke entering the subsequent treatment equipment is cleaner. The circulating output pump 42 installed at the bottom of the gas collecting end 41 is a fume transmission device, and the output pipeline of the treatment inlet pipe 44 directly extends to the cylinder inner cavity of the fume treatment cylinder 12. The bottom of the air collecting hopper 11 is also provided with a reverse blower 45. The back blower 45 is used for back blowing the gas collecting hopper 11 to clean dust when necessary, so as to prevent the particulate matters in the flue gas from accumulating and blocking in the hopper body.

The design ensures that the middle support shaft 91 can stably support the front spiral section 93, but the whole structure is still stable, so that a larger space exists at the position (input end) of the rear half section of the flue gas whitening machine barrel 25, condensate is concentrated in the region, the flue gas is preferentially contacted with a large amount of condensate after being introduced, and the flue gas and the condensate or chemical reagent are fully mixed and reacted to perform integral rapid cooling. The front half section (output end) of the flue gas whitening machine barrel 25 is supported by the middle support shaft 91 to the front spiral section 93, and the inner cylinder wall spiral blocks 95 and the front spiral section 93 are arranged in a staggered manner to form a complex twisting channel, so that a certain stagnation effect is formed on water liquid, formed liquid substances are retained in the flue gas whitening machine barrel 25, and treated flue gas subsequently enters the lifting machine barrel 28 through the lifting turnover pipe 64.
In one embodiment, referring to fig. 6, a ventilation chamber 71 is disposed in the circulation pump 24, a booster pump 72 is further connected to a side edge of the ventilation chamber 71, a closed valve core 82 is disposed in the ventilation chamber 71, and a regulator 81 for controlling the opening and closing of the closed valve core 82 is further disposed on the side edge of the circulation pump 24. The flue gas is injected into the flue gas whitening barrel 25 through a single valve at the transfer pump 24.
The flue gas is injected into the flue gas whitening machine barrel 25 through a single valve in the turnover machine pump 24, the turnover machine pump 24 is used as a key component for connecting the calciner and the flue gas whitening machine barrel 25, and an efficient flue gas flow and injection speed control system is formed by the ventilation cavity 71, the booster pump 72, the closed valve core 82 and the regulator 81 which are designed in the turnover machine pump 24. The ventilation area per unit time of the ventilation chamber 71 may be changed according to actual needs, thereby controlling the injection rate of the smoke. When the smoke needs to be injected rapidly, the ventilation area per unit time is the largest, the smoke enters the smoke whitening machine barrel 25 at a relatively high speed, and when the smoke needs to be injected slowly, the ventilation area per unit time is the largest, and the smoke injection speed is correspondingly reduced. This precise injection rate control helps to optimize the mixing and reaction process of the flue gas in the flue gas whitening barrel 25 and to improve the purification efficiency.
