Description
Technical field
The utility model relates to a kind of extraction tower for the production of nylon 6 slice.
Background technology
Existing a kind of extraction tower for the production of nylon 6 slice, include extraction tower, extraction water pot, dewaterer, between the lower end of described extraction tower and dewaterer, be connected with discharger, slush pump, the upper end of extraction tower is charging aperture, between extraction water pot and extraction tower, be also provided with heater, between heater and extraction water pot, be provided with circulating pump, the water side of dewaterer is connected with extraction water pot, and discharger is connected with extraction water pot.Extraction water enters extraction tower after circulating pump is sent into heater heating, after nylon 6 slice extraction, sends into dewaterer dehydration by discharger, slush pump, and the water that dewaterer is deviate from enters extraction water pot and recycles.
But, the extraction tower of this structure, heater is in the time heating extraction water; temperature can not be controlled well, often can, due to excess Temperature, cause temperature gradient distribution disorder; cause nylon 6 slice effect of extracting poor, and then cause easily producing monomer smog in the production of downstream, cause environmental pollution.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of extraction tower for the production of nylon 6 slice, its extraction temperature that can prevent nylon 6 slice is too high, causes temperature gradient distribution disorder, avoid downstream produce time to environment.
The technical solution of the utility model: a kind of extraction tower for the production of nylon 6 slice, include extraction tower, extraction water pot, dewaterer, between the lower end of described extraction tower and dewaterer, be connected with discharger, slush pump, the upper end of extraction tower is charging aperture, between extraction water pot and extraction tower, be also provided with heater, between heater and extraction water pot, be provided with circulating pump, the water side of dewaterer is connected with extraction water pot, discharger is connected with extraction water pot, it is characterized in that: on described extraction tower, be also connected with cooler, described cooler is provided with cooling water inlet, coolant outlet, coolant outlet is connected with extraction tower.
Adopt technique scheme, by the cooler arranging, in extraction tower when extraction water excess Temperature, pass into cooling water and enter in extraction tower after cooler is cooling, thus the extraction temperature of reduction nylon 6 slice, therefore, the nylon 6 slice extraction tower of this structure, its extraction temperature that can prevent nylon 6 slice is too high, causes temperature gradient distribution disorder, avoid downstream produce time to environment.
Further setting of the present utility model: described extraction tower is provided with two connectivity ports, and one of them connectivity port is positioned at the middle part of extraction tower, and another connectivity port is positioned at extraction tower bottom, described cooler is connected with two connectivity ports respectively.
Adopt above-mentioned further setting, the extraction tower of this structure and cooler connected mode, can be in extraction tower the extraction temperature in fast reducing extraction tower when excess Temperature, thereby improved production efficiency.
Further setting more of the present utility model: described extraction tower is provided with steam insulation cover outward, described steam insulation cover is provided with two one on the other.
Adopt above-mentioned further setting again, the steam insulation cover of setting can, in the time of extraction, can not decline temperature in extraction tower, thereby guarantees the effect of extracting of nylon 6 slice.
Further setting of the present utility model: be also provided with filter between described heater and circulating pump.
Adopt above-mentioned further setting, by the filter arranging, can prevent that some introduced contaminantses from entering in heater, thereby affect the effect of extracting of nylon 6 slice, cause in postorder nylon and contain impurity.
