Description

Polyester tail gas incineration device

Technical Field

The utility model belongs to the technical field of the polyester tail gas treatment technique and specifically relates to a polyester tail gas burns processing apparatus.

Background

Can produce all kinds of waste gas in polyester production, wherein mainly realize effective processing with acetaldehyde waste gas most difficult, can cause certain pollution to the environment, if the tail gas of original strip tower directly introduces the natural gas stove, but the in-process returns and produces a large amount of steam and comdenstion water, and the natural gas stove is very easily extinguished, unable normal processing waste gas can cause the unstability of production simultaneously, and the comdenstion water returns to containing a large amount of EG compositions in addition, becomes the pollutant.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical defects and providing a polyester tail gas incineration treatment device which can separate the condensed water in the polyester tail gas and then send the condensed water into a natural gas furnace.

In order to achieve the purpose, the utility model relates to a polyester tail gas incineration treatment device, which comprises a fan, a tail gas inlet pipe and a tail gas outlet pipe, wherein the tail gas inlet pipe is connected with the inlet of the fan, the tail gas outlet pipe is connected with the outlet of the fan, the tail gas outlet pipe is connected with a natural gas furnace, the tail gas inlet pipe is connected with polyester production equipment, the connecting position of the polyester production equipment and the tail gas inlet pipe is higher than the position of the fan, the connecting position of the natural gas furnace and the tail gas outlet pipe is higher than the position of the fan, and the tail gas inlet pipe and the tail gas outlet pipe at the position of the; the exhaust pipe is connected to the middle or upper part of the tail gas inlet pipe, the conveying pipe is arranged at the bottom of the condensed water storage tank, the conveying pipe is connected to the condensed water collecting box, and the water pump is arranged on the conveying pipe.

Above-mentioned technical scheme, with the tail gas that produces in the polyester production process, like the tail gas of production such as strip tower, advance the pipe through tail gas, the fan, the tail gas exit tube gets into the natural gas stove, tail gas advances the pipe and the tail gas goes out the intraductal in-process that flows can cool off at tail gas, so inside comdenstion water can be attached to on the lateral wall that tail gas exit tube and tail gas advance the pipe, because its tail gas advances the pipe, the tail gas exit tube is vertical upward design in fan department, so the comdenstion water can flow to the fan in along the pipeline wall, and carry to the comdenstion water storage tank through the drain pipe of fan bottom, realize the separation of. And at the in-process of drain pipe transport comdenstion water, can take away partly tail gas, this part tail gas returns the gathering in the comdenstion water storage tank, and it is carried to tail gas through the tail gas return pipe and advances intraduct through the fan again and carry to the natural gas stove, and safety high efficiency stability is high. When a certain amount of condensed water is accumulated in the condensed water storage tank, the condensed water can be conveyed to the condensed water collection tank through the water pump.

All be provided with the condenser rod in the pipe is advanced to the tail gas that is located vertical ascending at fan department and the tail gas exit tube, the condenser rod interval sets up on tail gas advances pipe and tail gas exit tube, and the both ends of condenser rod extend to the outside that tail gas advances pipe, tail gas exit tube. The design of this structure can utilize the heat conductivility of condenser rod, will advance the pipe to tail gas and tail gas outlet pipe's tail gas cools down, can make the steam in the tail gas gather on the condenser rod simultaneously, the better separation of steam, the comdenstion water in the realization tail gas.

The condensation rod is of a hollow structure, and two ends of the condensation rod are communicated with the outside. This structure can further promote the cooling effect of condensation bar to tail gas for steam and tail gas separation are more thorough, thereby ensure that the combustion stability of natural gas stove is higher.

The utility model provides a polyester tail gas incineration disposal device, it can realize through reasonable structural design that the steam in the tail gas separates to realize that polyester tail gas directly gets into the natural gas stove and carry out incineration disposal, safe and reliable.
