Abstract
The utility model relates to a kind of regenerative apparatus of refinery atmospheric storage-tank waste gas, for Petrochemical Enterprises atmospheric storage tank tank deck tail gas recycle.It discloses the Water Tank being no less than, Water Tank has tank deck passage, tank deck passage leads to injection blwr negative pressure termination, the head of described injection blwr has delivery pipe to be communicated with vapor-liquid separator, vapor-liquid separator top bottom respectively has delivery pipe, there are two delivery pipings on described top, article one, after controlling gate valve, be communicated with refinery's low pressure gas flare system of this device, another enters previous Water Tank and carries out pressure regulation after control cock, described bottom has lime set after U-shaped sealing water pipe, to enter second Water Tank by delivery pipe, straight-through spray blwr negative pressure end after control cock is entered again after second Water Tank has pipeline to be connected with boost pump.The utility model introduces refinery's low pressure gas flare system by after the tail gas supercharging of atmospheric storage tank top, and the power fluid source of injection blwr and gas source are all that the useless source of this device utilizes.
Description
Technical field
The utility model relates to the recovery of Petrochemical Enterprises atmospheric storage tank top tail gas.
Background technology
Petrochemical Enterprises atmospheric storage tank mainly comprises sour water tank, oil product tank, alkaline residue tank, coke-cooling waste water tank.Owing to pressing " vertical and cylindrical system welding storage oil tank design codes " (GB50341-2003), the design pressure of fixed-roof oil tank should get normal pressure or close to normal pressure (negative pressure should not be less than 0.49kPa), when standard compliant appendix A relevant regulations, maximum pressure is 6.0 kpa, general operation range of pressure-0.49 ~ 2.0 kPa, operating flexibility is little.For avoiding in use crossing degree malleation or excessive negative pressure and damage tank body, the straight open to atmosphere design of general employing, the pernicious gas such as hydro carbons, benzene homologues, hydrogen sulphide, phenols, mercaptan causing storage tank to discharge high concentration in storing process is difficult to hermetic reclaim, become the source of pollution of the main refining losses source of Petrochemical Enterprises and volatile organic matter (VOC) discharge beyond standards, even if discharge air after adopting alkali lye or other absorption measure, the environment evil breath pollution that exhaust emissions causes also cannot be eliminated.
Summary of the invention
The purpose of this utility model is to provide a kind of regenerative apparatus of Love psychology tank waste gas, it introduces refinery's low pressure gas flare system by after the tail gas supercharging of atmospheric storage tank top, and spray the power fluid source of blwr and pneumatic source for this device and to give up source utilization, solve atmospheric storage tank operating pressure low, operating flexibility is little, tank deck tail gas is difficult to a difficult problem for hermetic reclaim, realizes zero-emission object.Safety of operation is reliable, and one-time investment is few, and operating cost is low.
Technical solution of the present utility model is, at existing sour water tank, oil product tank, alkaline residue tank, the atmospheric storage tanks such as coking cold water tank, on the basis of refinery's low pressure gas flare system, the utility model is at the sewage storage tank being no less than, sewage storage tank has tank deck passage, tank deck passage leads to injection blwr negative pressure termination, the head of described injection blwr has delivery pipe to be communicated with vapor-liquid separator, vapor-liquid separator top bottom respectively has delivery pipe, there are two delivery pipings on described top, article one, after controlling gate valve, be communicated with refinery's low pressure gas flare system of this device, another enters previous Water Tank and carries out pressure regulation after control cock, described bottom has lime set after U-shaped sealing water pipe, to enter second Water Tank by delivery pipe, straight-through spray blwr negative pressure end after control cock is entered again after second Water Tank has pipeline to be connected with boost pump.
The above sewage tank skin bottom has sewage input pipe to input.
Water Tank described in the utility model is two, and one is the sewage storage tank of water feed apparatus, and one is the sewage storage tank of lime set in air inlet-vapour separator lower channel, has pipeline communication between these two storage tanks.
The utility model has the advantages that:
(1) " a kind of recovery of Love psychology tank waste gas " introduce refinery's low pressure gas flare system by after the supercharging of normal pressure Water Tank tank deck tail gas, or guide to other emission-control equipment and focus on, thoroughly solve the pollution problem of Water Tank exhaust emissions.
(2) sewage (also circulating water, condensed water, other waste water or fresh water can be used) of Water Tank self is adopted after boost pump as the supercharging propulsive effort of jet ejector, neither produce new sewage, again not by the restriction of steam source, do not need cooling infrastructure, reduce cost.
(3) when system pressure is too low, adopt device in Gas to supplement, in order to avoid reduce the calorific value of gas train, and save nitrogen cost.
(4) the method has that one-time investment is few, safety of operation is reliable, operating cost is low, decreases the discharge of refinery's volatile organic matter (VOC), extends to the industries such as chemical industry, chemical fibre, agricultural chemicals.
Accompanying drawing explanation
Fig. 1 the utility model organigram.
Detailed description of the invention
According to Fig. 1, there is Water Tank 1, Water Tank sewage is as continuous propulsion source, have and spray blwr 3, spray the negative press bond tank deck waste gas of blwr 3, the head spraying blwr 3 has delivery pipe to enter solution-air device disconnector 5, the top of described vapor-liquid separator 5 has delivery piping to be divided into two tunnels after controlling gate valve 6, refinery's low pressure gas flare system of one Lu Liantongben device, another enters the pressure regulation of Water Tank 1 for Water Tank by pipeline after control cock 8, there is delivery pipe the bottom of vapor-liquid separator 5, lime set straight-through Water Tank 2 after U-shaped sealing water pipe is had in described delivery pipe, Water Tank 2 has pipeline to be connected with boost pump 7 and leads to the rear straight-through spray blwr negative pressure end of control cock 4 again, discharge is controlled in described injection blwr 3, vapor-liquid separator 5 is entered after being pressurized to by the tank deck tail gas of 0 ~ 1.5kPa, when vapor-liquid separator 5 pressure is greater than refinery's low pressure gas flare system, gas self-pressure enters refinery's low pressure gas flare system (6 ~ 19kPa) and control cock 8 enters Water Tank 1, another lime set self-pressure is back to the object that Water Tank 2 realizes tail gas hermetic reclaim.There are high-concentration sulfur-containing or the input of oily sewage input pipe in Water Tank 1 tank skin lower end.Pipeline communication is had between two Water Tanks.
The utility model, when device in Gas is forced down, can adopt nitrogen immediately to enter control cock 8.
