Abstract
The utility model relates to a kind of gas final cold tower with heating unit except naphthalene system, comprise primary cooler, phlegma storage tank, condensate pump, aqua ammonia pump, cleaning liquid pump, well heater, scavenging solution storage tank, Ammonia vessel, final cooling tower, valve I, valve II and valve III, the condensate outlet of primary cooler is connected to the import of phlegma storage tank by pipeline, described phlegma storage tank is connected with the phlegma import of well heater by condensate pump I, the condensate outlet of described well heater is connected to scavenging solution storage tank by pipeline, Ammonia vessel is connected with scavenging solution storage tank by aqua ammonia pump, scavenging solution storage tank is connected with the flusher of final cooling tower tower top by cleaning liquid pump.Naphthalene purification system washed by gas final cold tower of the present utility model, the phlegma of primary cooler is utilized to be washed out by the naphthalene in coal gas, avoid using traditional Processing Method for Washing Naphthalene Used of Light Tar to cause tar component easy secondary attachment pipeline, thus cause the frequent problem that final cooling tower is cleaned.
Description
Technical field
The utility model relates to coal tar chemical technology field, is specifically related to a kind of gas final cold tower with heating unit except naphthalene system.
Background technology
Need in chemical process finally to cool coal gas, owing to containing a large amount of coal tar in coal gas, naphthalene in final process of cooling in coal tar is easily attached on whole cold pipeline, cause whole chemical system resistance higher, need regularly to clean, and on the low side in north of china in winter temperature, the very easily crystallization of the naphthalene in phlegma, in order to prevent the crystallization of naphthalene in phlegma, need to improve condensate temperature.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides a kind of gas final cold tower with heating unit except naphthalene system, washes when naphthalene runs and is heated phlegma by steam, prevent the naphthalene temperature in phlegma too low and crystallization at phlegma.
The utility model is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of gas final cold tower with heating unit is except naphthalene system, comprise primary cooler, phlegma storage tank, condensate pump, aqua ammonia pump, cleaning liquid pump, well heater, scavenging solution storage tank, Ammonia vessel, final cooling tower, valve I, valve II and valve III, described heater body has heat exchanging pipe, and interchanger has steam inlet and vapour outlet, the condensate outlet of described primary cooler is connected to the import of phlegma storage tank by pipeline, valve I is arranged on the pipeline between primary cooler and phlegma storage tank, described phlegma storage tank is connected with the phlegma import of well heater by condensate pump I, valve II is arranged on the pipeline between condensate pump I and well heater, the condensate outlet of described well heater is connected to scavenging solution storage tank by pipeline, described Ammonia vessel is connected with scavenging solution storage tank by aqua ammonia pump, scavenging solution storage tank is connected with the flusher of final cooling tower tower top by cleaning liquid pump, valve III is arranged on the pipeline between cleaning liquid pump and final cooling tower.Described flusher is spray line.
beneficial effect
Naphthalene purification system washed by gas final cold tower of the present utility model, the phlegma of primary cooler is utilized to be washed out by the naphthalene in coal gas, avoid using traditional Processing Method for Washing Naphthalene Used of Light Tar to cause tar component easy secondary attachment pipeline, thus cause the frequent problem that final cooling tower is cleaned, and wash when naphthalene runs at phlegma and by steam, phlegma is heated, prevent the naphthalene temperature in phlegma too low and crystallization.
