The device can safe and reliable completion waste gas recovery handle, both avoided environmental pollution, reduced the potential safety hazard, realized simultaneously having practiced thrift the energy by waste gas recovery.
Description
Technical field
The utility model relates to a kind of regenerative apparatus of oil tank waste gas.
Background technology
Many devices volatile liquid in oil tank, along with the change of temperature and pressure, volatile liquid is easy to become gas, and former this gas is all discharged in air as waste gas, but this mode both contaminated environment, cause potential safety hazard because waste gas is inflammable again.Recently seldom have in line in air, being discharged in air environment after being usually all through process, although this mode avoids contaminated environment, is not a kind of energy-conservation processing mode.
Utility model content
In order to solve the above problem existed in background technology, the utility model provides a kind of oil tank emission-control equipment, and what this device can be safe and reliable completes waste gas recovery process, both environmental pollution was avoided, reduce potential safety hazard, achieve waste gas recovery simultaneously, save the energy.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of oil tank waste gas recovering device, comprise the gas conduit being arranged on roof, it is characterized in that: described gas conduit extend towards the oblique below of oil tank and with compressed tanks be on the ground set be connected, the top of compressed tanks is extended with the first arm and the second arm, first arm is connected with air compressor, and air compressor is connected with air by extension tube attached, and the second arm is connected with extension tube attached, second arm is provided with the first automatic valve, gas conduit is provided with the second automatic valve; The bottom of compressed tanks is connected with liquor pump, and liquor pump is communicated with the sidepiece of oil tank by oil pipe; The top of oil tank is provided with weather gauge, and weather gauge is connected with the first automatic valve and the second automatic valve communication.
The beneficial effects of the utility model are: the waste gas recovery work automatically completing oil tank, recovery degree is high, and safety is high.This device can be safe and reliable complete waste gas recovery process, both avoided environmental pollution, reduced potential safety hazard, achieved waste gas recovery simultaneously, saved the energy.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the structural representation of waste gas recovering device described in the utility model;
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
As shown in Figure 1, liquid 2 has been deposited in oil tank 1, liquid 2 is the volatile liquids such as gasoline, upper space in oil tank 1 is full of the waste gas 3 after liquid 2 volatilization, oil tank 1 is provided with waste gas recovering device, waste gas recovering device comprises the gas conduit 5 being arranged on oil tank 1 top, gas conduit 5 extend towards the oblique below of oil tank 1 and with compressed tanks 7 be on the ground set be connected, the top of compressed tanks 7 is extended with the first arm 9 and the second arm 10, first arm 9 is connected with air compressor 14, air compressor 14 is connected with air by extension tube attached 13, second arm 10 is connected with extension tube attached 13, second arm is provided with the first automatic valve 12, gas conduit 5 is provided with the second automatic valve 11,
The bottom of compressed tanks 7 is connected with liquor pump 8, and liquor pump 8 is communicated by the sidepiece of oil pipe 6 with oil tank 1.
The top of oil tank 1 is provided with weather gauge 4, and weather gauge 4 is connected with the first automatic valve 12 and the second automatic valve 11 communication.
The working process of this novel described waste gas recovering device is: under normal condition, first automatic valve 12 keeps closing, second automatic valve 11 stays open, waste gas 3 enters in compressed tanks 7 by gas conduit 5, when the gas 3 that weather gauge 4 detects in oil tank 1 exceedes default force value, second automatic valve 11 is closed, air compressor 14 pressurizes in compressed tanks 7, after gaseous tension in tank 7 to be compressed reaches setting value, waste gas 3 is by compression and back liquid 2, stop air compressor 14, open liquor pump 8, by liquid 2 pumpback bottom compressed tanks 7 in oil tank 1.After liquid pumpback in tank 7 to be compressed, close the second automatic valve 11, open the first automatic valve 12, the gas that air compressor 14 is carried is discharged in air by the second arm 10, keep the equilibrium of pressure of air compressor 14, thus complete a removal process.Complete the waste gas recovery work of oil tank and so forth.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
