Abstract
The utility model relates to a carbon no. 5 distillates fractionally equipment vacuum pump tail gas recovery device, include: heat exchanger, lime set are received jar and are retrieved the pump, and wherein the heat exchanger is taken over and is connected with vacuum pump tail gas delivery line, and the leakage fluid dram of heat exchanger is connected the lime set and is received jar, and the lime set is received the jar and is connect to recovery pump state through delivery line, the gas vent of heat exchanger has met exhaust pipe, the last unloading control valve that has connect of exhaust pipe, the low warm water temperature that the heat exchanger let in is no longer than 5 DEG C. The utility model discloses a to vacuum pump tail gas system, concentrate the condensation with vacuum tail gas and retrieve, retrieve the component that the condensation point is high, increase economic profit, reduce environmental pollution.
Description
Technical field
This utility model relates to a kind of carbon five fractionating technology, and a kind of carbon five fractionation apparatus is true
Empty pump device for recovering tail gas.
Background technology
Carbon five is the resource of a kind of preciousness, can produce the chemical products of a series of high added values by it,
The exploitation of countries in the world common concern carbon five.
Carbon five has another name called lighter hydrocarbons, and China produces nearly ten million ton per year, but effectively utilizing of carbon five is always a difficulty
Topic.When carbon five fractionation apparatus is properly functioning, tail gas of vacuum gas pump temperature is 15-20 degree Celsius, in tail gas
There is also the hydrocarbon gas that part can condense out, it is impossible to reclaim, but be directly vented, to environment
Pollute, lose huge.
Utility model content
Cannot reclaim environment etc. for carbon in prior art five fractionation apparatus tail gas of vacuum gas pump
Deficiency, the technical problems to be solved in the utility model is to provide one and can vacuum tail gas concentration be condensed back
Receive, reduce the carbon five fractionation apparatus tail gas of vacuum gas pump retracting device of environmental pollution.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
This utility model one carbon five fractionation apparatus tail gas of vacuum gas pump retracting device, including: heat exchanger,
Lime set receives tank and recovery pump, and wherein heat exchanger adapter is connected with tail gas of vacuum gas pump output pipe, changes
The leakage fluid dram of hot device connects lime set and receives tank, and lime set receives tank and is connected to recovery pump by output pipe.
The air vent of heat exchanger is connected to gas exhaust piping, gas exhaust piping is connected to be vented control valve.
The water at low temperature water temperature that heat exchanger is passed through is less than 5 DEG C.
Described heat exchanger is fixed tube-sheet exchanger, double-tube heat exchanger.
This utility model has the advantages that and advantage:
1. this utility model is by the tail gas of vacuum gas pump system reform, concentrating condensation to reclaim vacuum tail gas,
Component high for condensation point is reclaimed, increases economic well-being of workers and staff, reduce environmental pollution.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein, 1 is heat exchanger, and 2 receive tank for lime set, and 3 is recovery pump, and 4 is emptying control valve, 5
For tail gas of vacuum gas pump pipeline, 6 is water at low temperature watering pipeline, and 7 is water at low temperature water return pipeline, and 8 for not coagulate
Gas blowdown piping.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
As it is shown in figure 1, this utility model carbon five fractionation apparatus tail gas of vacuum gas pump retracting device, including:
Heat exchanger 1, lime set receive tank 2 and recovery pump 3, wherein heat exchanger 1 adapter and vacuum pump 5 tail gas
Output pipe connects, and the leakage fluid dram of heat exchanger 1 connects lime set and receives tank 2, and lime set receives tank 2 by defeated
Go out pipeline and be connected to recovery pump 3.
The air vent of heat exchanger 1 is connected to gas exhaust piping, gas exhaust piping is connected to be vented control valve 4.This reality
Executing in example, heat exchanger 1 uses fixed tube-sheet exchanger.
During use, the internal comb entrance of heat exchanger is passed through the water temperature low-temperature circulating water less than 5 DEG C, beats
Opening the output pipe control valve of tail gas of vacuum gas pump 5, tail gas of vacuum gas pump is entered by tail gas of vacuum gas pump pipeline 5
Entering heat exchanger 1, carry out energy exchange with the comb being passed through low-temperature circulating water, in hydrocarbon gas, condensation point is high
Component (carbon four, carbon five) is condensed into liquid, flows out through leakage fluid dram, enters lime set and receives in tank 2.
After lime set reception tank 2 is stored in certain liquid measure, recovery pump 3 starts, and lime set output is entered and recycles
Treatment process.
The component (carbon three) that in hydrocarbon gas, condensation point is relatively low is directly by being installed on the aerofluxus of heat exchanger 1
The fixed gas blowdown piping 8 of mouth is vented.
Vacuum tail gas, by the device tail gas of vacuum gas pump system reform, is concentrated and is condensed back by this utility model
Receive, component high for condensation point is reclaimed, decrease gas discharge, reduce environmental pollution, increase economy and receive
Benefit.
