PTA refining condensate recovery device

Abstract

The invention provides a PTA refining condensate recovery device, which comprises a main body; an impurity removing mechanism; a filtering mechanism; a collection mechanism; a control mechanism, wherein the control mechanism comprises a sliding groove, a fixing block, an air pipe, a fixing funnel, an extrusion plate, a fixing rod, a floating ball and a supporting rod, the interior of the sliding groove is slidably connected with the extrusion plate with the semicircular side wall, and the supporting rod is slidably connected with the interior of the air pipe and the interior of the collectingmechanism; a condensation mechanism; a water storage mechanism; and a flushing mechanism, wherein the flushing mechanismv comprises a hose, a water inlet pipe, a pressing rod, a piston, a fixing ball,an air inlet pipe, spray heads and a coil pipe, the spray heads are installed at the top end of the coil pipe at equal intervals, the piston with the inclined top end is slidably connected to the interior of the fixing ball, and the piston is slidably connected to one end of the air inlet pipe. According to the invention, the PTA refining condensate recovery device has the advantages that condensate is added into the washing tower, water cost is reduced, and powder in the washing tower is convenient to clean.

Description

technical field [0001] The invention relates to the technical field of PTA equipment, in particular to a PTA refining condensate recovery device. Background technique [0002] In the PTA device, a certain amount of solid powder will be entrained in the air released by the refining dryer. After passing through the high-temperature and high-pressure gas into the washing tower for washing, the powder is separated, but a large amount of water is entrained in the gas, and finally passes through the heat exchanger. Condensation to achieve gas-liquid separation. [0003] However, the current practice of the PTA factory is to discharge the condensed water directly into the sewage treatment unit, which increases the load of sewage treatment, reduces the water volume inside the washing tower, and requires constant replenishment, which increases the cost of water use, and a large amount of powder Accumulation inside the bottom of the washing tower not only blocks the pipeline, but als...
