Abstract
The utility model belongs to the technical field of chemical fiber production equipment and specifically relates to a waste water overflow arrangement esterifies, it includes esterification technique tower, plate heat exchanger, cooler and holding vessel, top and the bottom of holding vessel between be connected through communicating pipe, be connected with the delivery pipe on communicating pipe, the delivery pipe is connected with the waste water jar, is connected with the overflow pipe on the holding vessel below the height of delivery pipe and communicating pipe junction, the other end of overflow pipe is connected on the delivery pipe between communicating pipe and no. Two control valves. This waste water overflow arrangement esterifies utilizes in the overflow pipe of the middle part of holding vessel setting and being connected of delivery pipe, and under the higher circumstances of holding vessel liquid level, no. Three the control valve is opened, and then the overflow pipe can be followed in discharging duct flow to waste water jar to partial liquid to ensure that the liquid level in the holding vessel keeps the setting value, and then the flowing pressure in reducible cooler to the holding vessel, reduce the use power of the fan in the cooler, reduce the energy consumption.
Description
Technical field
This utility model relates to field of chemical fiber production equipment, especially a kind of esterification waste water overflow mechanism.
Background technology
Producing esterification steam in polyester esterification reaction production process, esterification steam forms liquid under the effect of heat exchanger and air cooler, is stored in holding vessel, and partially liq is recycled by pump, and part then overflow is to waste water tank; But due to the effect of the pressure in holding vessel, cause the liquid in holding vessel cannot overflow efficiently to waste water tank, cause that the Liquid level in holding vessel is accurate, and then impact be normal produces.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction to solve the deficiency of above-mentioned technology, can effectively guarantee that the liquid level in holding vessel is precisely maintained at the esterification waste water overflow mechanism of setting position.
In order to achieve the above object, esterification waste water overflow mechanism designed by this utility model, it includes esterification technique tower, plate type heat exchanger, cooler and holding vessel, described esterification technique tower is connected with plate type heat exchanger by pipeline, plate type heat exchanger is connected with cooler by pipeline, and cooler is connected with holding vessel; It is connected by pipeline between holding vessel with esterification technique tower, the pipeline between holding vessel and esterification technique tower is provided with delivery pump; It is connected by connecting pipe between the top of described holding vessel and bottom, connecting pipe is connected to delivery pipe, delivery pipe is connected with waste water tank, connecting pipe above holding vessel is provided with a control valve, delivery pipe is provided with No. two control valves, within the junction of described delivery pipe and connecting pipe is positioned at the tank body altitude range of holding vessel; Being connected to overflow pipe on holding vessel below the height of delivery pipe and connecting pipe junction, the other end of overflow pipe is connected on the delivery pipe between connecting pipe and No. two control valves, is provided with No. three control valves on overflow pipe; The top of holding vessel is provided with evacuated tube, evacuated tube arranges exhaust-valve.
The esterification waste water overflow mechanism that this utility model is obtained, utilize the connection of overflow pipe and the delivery pipe arranged at the middle part of holding vessel, when holding vessel liquid level is higher, No. three control valves are opened, then partially liq can flow in waste water tank from overflow pipe through delivery pipe, so that it is guaranteed that the liquid level in holding vessel keeps setting value;And then cooler can be reduced to the flowing pressure in holding vessel, reduce the use power of blower fan in cooler, reduce energy consumption.
