Description
Technical field: the invention belongs to chemical industry equipment, particularly the chemical industry vapour-recovery unit.
Background technology: triethylene glycol is a kind of water white neutral oily liquids; When being heated to boiling temperature, the polyphosphazene polymer ester material there are alcoholysis and dissolution; And have no side effect to being cleaned part, be specially adapted to macromolecule polyester cleaning of materials such as filter core, measuring pump and spinneret.But, in cleaning, can make the triethylene glycol vaporize because of hot-spot, these steam have very strong excitant, and are inflammable and explosive, poisonous, and people's eyes and respiratory system had than major injury.Directly discharging not only pollutes the environment if do not deal with, and the infringement health also can be cleaned cost because of a large amount of evaporations of triethylene glycol increase.Existing equipment does not have supporting retracting device, and directly discharging does not still have detection means to the harm of environment and human body, and it is not obvious simply to cool off recovering effect, and each the cleaning has hundreds of kilograms triethylene glycol emission loss, and economic loss is very big.
Summary of the invention: the purpose of this invention is to provide a kind of triethylene glycol and clean vapour-recovery unit, effectively reclaim the steam that the triethylene glycol cleaning equipment produces, and carry and return hospitality recycle in the equipment of washing, reduce pollution emissions simultaneously.The objective of the invention is to realize like this: triethylene glycol cleans vapour-recovery unit, comprises condenser, gas-liquid separator and gatherer.Triethylene glycol clean vapour-recovery unit be positioned at the triethylene glycol cleaning oven above.Have the steam exhaust-gas pipeline to connect first-stage condenser on triethylene glycol cleaning oven top, first-stage condenser top has blast pipe to connect the one-level gas-liquid separator, and the bottom has discharging tube to be communicated with the triethylene glycol cleaning oven; One-level gas-liquid separator top has blast pipe to connect secondary condenser, and the bottom has discharging tube to connect the triethylene glycol cleaning oven; Secondary condenser top has blast pipe to connect the secondary vapour liquid separator, and the bottom has discharging tube to connect the waste collection device; Secondary vapour liquid separator top has blast pipe to be communicated with atmosphere, and the bottom has discharging tube to connect the waste collection device; The cooling water inlet and outlet pipe lines connects triethylene glycol cleaning oven, first-stage condenser and secondary condenser respectively.
Described first-stage condenser is the above shell and tube stainless heat exchangers of two strokes, and install at inclination 10-15 degree angle, and heat exchanger tube side medium is a cooling water, and shell side is a triethylene glycol steam.The one-level gas-liquid separator is that stainless steel is columnar structured; In establish spoiler with catch the mist device, spoiler is semicircle corrosion resistant plate, is welded in the cylinder alternately up and down; Catch the mist device and constitute, be fixed on all around on the cylindrical shell of spoiler top by the multilayer stainless steel metal wire.
Described secondary condenser is the vertical one-stroke tubular heat exchanger of placing, and tube side leads to steam, and shell side leads to cooling water.The secondary gas-liquid separator is the stainless steel filtering net that a band metallic framework is housed in cylindrical shell.
Triethylene glycol cleans the triethylene glycol vapor recycle utilization that vapour-recovery unit reclaims, and has produced distinct economic, has prevented pollution on the environment simultaneously again.This device also can be used for organic steam condensing and recycling such as methyl alcohol, ethylene glycol, reduces the pollution of directly discharging formation and the waste of resource
Description of drawings: Fig. 1 is the structural representation that triethylene glycol cleans vapour-recovery unit.Fig. 2 is the structural representation of one-level gas-liquid separator.
The specific embodiment: be further described below in conjunction with accompanying drawing.
As shown in Figure 1, triethylene glycol cleans vapour-recovery unit, comprises condenser, gas-liquid separator and gatherer.Triethylene glycol clean vapour-recovery unit be positioned at triethylene glycol cleaning oven 1 above so that condensate liquid is back to downwards in the triethylene glycol cleaning oven.Triethylene glycol cleaning oven top has the steam exhaust-gas pipeline to connect first-stage condenser 3; Triethylene glycol steam gets into first-stage condenser by discharge duct in the stove; First-stage condenser 3 is the above shell and tube stainless heat exchangers of two strokes, and install at inclination 10-15 degree angle, refluxes so that condensate liquid is concentrated; Heat exchanger tube side medium is a cooling water, and shell side is a triethylene glycol steam.First-stage condenser top has blast pipe to connect one-level gas-liquid separator 4, and the bottom has discharging tube 2 to be communicated with the triethylene glycol cleaning oven.Most of triethylene glycol steam can be condensed into liquid state in cooling procedure in first-stage condenser, deposits to the bottom and is back to cleaning oven through discharging tube.Blast pipe gets into the one-level gas-liquid separator to other liquid-vapor mixture matter from cooler top; One-level gas-liquid separator 4 is that stainless steel is columnar structured, and is as shown in Figure 2, in establish spoiler 1 and catch mist device 9; Spoiler is semicircle corrosion resistant plate; Be welded on alternately in the flexible body up and down, catch the mist device and constitute, be fixed on all around on the cylindrical shell of spoiler top by the multilayer stainless steel metal wire.One-level gas-liquid separator top has blast pipe to connect secondary condenser 6, and the bottom has discharging tube to connect the triethylene glycol cleaning oven.Gas-liquid mixture is through initial gross separation in the one-level gas-liquid separator, and gaseous material gets into secondary condenser by blast pipe, and lime set gets into the triethylene glycol cleaning oven by the bottom discharging tube.Secondary condenser 6 is vertical one-stroke tubular heat exchangers of placing, and tube side leads to steam, and shell side leads to cooling water.Secondary condenser top has blast pipe to connect secondary gas-liquid separator 7, and the bottom has discharging tube to connect waste collection device 8.Exhaust emissions after the gas-liquid mixture that secondary condenser comes out further separates through the secondary gas-liquid separator is again gone into atmosphere, and condensate liquid gets into the waste collection device.Secondary gas-liquid separator 7 is stainless steel filtering nets that a band metallic framework is housed in cylindrical shell.Secondary gas-liquid separator top has blast pipe to be communicated with atmosphere, and the bottom has discharging tube to connect the waste collection device; Cooling water inlet and outlet pipe lines 5 connects triethylene glycol cleaning oven, first-stage condenser and secondary condenser respectively.
