摘要： A method and device are provided for purifying and recycling water vapor from a coal drying process. Included are a temperature-lowering and dehumidifying process, a flash distillation stripping process, and a vacuum condensing process. A condensing tower receives a temperature-lowered exhaust gas with high humidity from a cooling tube and a condensed water of 5˜60° C. from a flash distillation tank, allowing the exhaust gas and the condensed water to contact each other in a vapor-liquid reverse manner, to lower the temperature and dehumidify the exhaust gas. The flash distillation tank performs a vacuum flash distillation to the condensing water pumped therein from the condensing tower. Water vapor of 5˜60° C. evaporated through flash distillation in the flash distillation tank enters into the demisting washer to be dehumidified and then is condensed. The condensed water in the vapor condenser is transferred into a recycled water tank. Non-condensable gas is discharged out.

摘要： The present invention relates to a method for processing acetic acid solvent in an oxidizing unit of a PTA industrial apparatus; said method uses a pressure filter machine to filter crude terephthalic acid slurry, and then, using a multi-stage counter-current method, uses washing water to wash the acetic acid solvent, and, by means of setting up a bias-current and drainage, prevents residual liquid in the filtrate pipe from entering the next area following the rotation of the pressure filter machine, improving washing efficiency and reducing the amount of washing water; the present invention integrates the processes of filtering and washing crude terephthalic acid into a single pressure filter machine, such that the process is shorter, the occupied floor space is reduced, and energy consumption is lower. A method feeding nitrogen gas into the mother liquor tank and washing liquid tank is used to regulate the pressure balance of the system.

摘要： A dehumidifying tower having a washing section, a flash-distilling section, and a condensing section. In the washing section, exhaust gas is washed with a cooling liquid to remove at least a portion of solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section flash-distills the cooling liquid used in the washing section to produce a cooled cooling liquid and a cooling liquid vapor. Cooling liquid produced by flash-distillation enters the washing section. The flash-distilling section is in gas-phase isolation from the washing section. The condensing section condenses the cooling liquid vapor produced by flash-distillation. The condensing section is configured to be in gas-phase communication with and liquid-phase isolation from the flash-distilling section, and be in both gas-phase and liquid-phase isolation from the washing section.

摘要： The invention relates to an exhaust gas separating tower, comprising a washing section, a flash-distilling section above the washing section, and a liquid seal means between the flash flash-distilling section and the washing section. The washing section is configured for washing exhaust gas entering the tower with a cooling liquid to at least partially remove solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section is configured for flash-distilling the cooling liquid from the washing section to produce a cooled cooling liquid and a cooling liquid vapor. The liquid seal means is configured so that the cooling liquid produced by flash-distillation can enter the washing section through the liquid seal means while the flash-distilling section is in gas-phase isolation from the washing section, wherein a pressure in the flash-distilling section is lower than that in the washing section.

摘要： A method for drying high moisture, low calorific value lignite for a generating set and recovering water contained therein and an apparatus thereof mainly consist of a rotary steam tube dryer, a washing cooling tower, a coal mill, a first bag filter, a condenser, a weighing surge bunker, a water ring vacuum pump and so on. A drying system is integrated with a milling system, every dryer and the corresponding coal mill are disposed and are directly connected via a surge bunker, thereby not only saving the heat lost during the transportation of pulverized coal, but also omitting a long-distance transportation from a conventional drying system to a conventional milling system, effectively avoiding such phenomena as dust pollution, waste and spontaneous combustion during transportation and transshipment, simplifying the coal preparation system employed in the front-end process of drying.
