Description
Technical field
The utility model relates to a kind of heat pipe-type device for recovering oil and gas, is applicable to the preliminary recovery of various volatility oil gas.
Background technology
The oil gas evaporation that oil product can't be avoided bringing because of oil gas volatilization in processing and storing process loses, and not only causes the pollution of environment, has also wasted resource.Oil gas reclaims and is paid attention to widely at present, and its method also has a lot, like condensation method, absorption process, absorption method etc.But in the aforementioned several method; Adopt which kind of method all to need sizable consumption of power; And the oil gas temperature improves when the oil product supplied materials, can make that gas concentration promotes thereupon in the waste gas, and the treatment effect of device for recovering oil and gas can be a greater impact because of impact load.Adopt methods such as condensation, absorption, absorption all need tank top be carried out the airtight oil gas of collecting, the oil gas after the recovery mixes can not be realized separating.For example; When existing gasoline tank has the coal tar naphtha storage tank again in the finished oil tank field; The oil gas that reclaims is blended in together; Returning any one storage tank all can influence the quality of product in the storage tank, therefore possibly need follow-up treating process to separate or be directed against different oil products a plurality of device for recovering oil and gas are set.
CN1631748A discloses a kind of device for recovering oil and gas; Used the material that can make the oil gas coalescence, can be recovered in and reached super-saturated oil gas in the storage tank, but since in the whole storage tank temperature contrast limited; The degree of condensation of oil gas is less, so oil gas recovery rate is not ideal enough.
Summary of the invention
To the deficiency of prior art, the utility model provides the consumption of a kind of not energy requirement to carry out the preliminary device that reclaims of oil gas.
The utility model heat pipe-type device for recovering oil and gas comprises cylindrical shell, and the cylindrical shell lower end is an admission port; The cylindrical shell upper end is an air extractor duct; Hot tube heat exchanger is set, and hot tube heat exchanger the latter half is that the heat pipe hot junction is arranged on bottom in the cylindrical shell, and hot tube heat exchanger the first half is that the heat pipe cold junction is arranged on the cylindrical shell outside.
In the utility model heat pipe-type device for recovering oil and gas, the hot junction of heat pipe and the cold junction of heat pipe all are provided with metal fin.The hot side fin horizontal arrangement of heat pipe or vertical the layout, the cold junction fin adopts horizontal arrangement.
In the utility model heat pipe-type device for recovering oil and gas, the quantity of heat pipe gets final product with evenly distributed full cylindrical shell.The cylindrical shell shape of cross section can adopt circle or polygon etc.
In the utility model heat pipe-type device for recovering oil and gas, the cylindrical shell internal upper part is provided with the oil mist trapping device, improves the mist of oil organic efficiency.The oil mist trapping device adopts the lamination coating of big flux, high interdiction capability to make.
In the utility model heat pipe-type device for recovering oil and gas, the hot junction outer setting wire gauze protective case of heat pipe with the protection heat pipe, does not influence radiating effect simultaneously.
The utility model heat pipe-type device for recovering oil and gas adopts heat pipe, and outside air is done cold junction, and oil gas is cooled off.Hot junction and cold junction at heat pipe installs fin respectively additional simultaneously, and the heat-obtaining of heat pipe, heat-sinking capability are further improved, and the temperature difference that can make the oil gas and the external world guarantees that less than 5 ℃ oil gas is fully cooled off.In the winter time, oil gas is cooled to lower temperature, and more oil gas is condensed, thereby reaches the higher percent recovery.
The utility model heat pipe-type device for recovering oil and gas adopts the material for trapping of the lamination coating of big flux, high interdiction capability as mist of oil, and mist of oil forms bulky grain at the lamination coating surface aggregation, finally because of gravity falls, gets back in the former storage tank.The resistance of lamination coating is very little, and when gas speed reached 5m/s, its pressure drop can both be controlled in the 100Pa; Therefore can the utility model be installed between the breathing valve and the equipment mouth of pipe on oil product storage tank top; Can not influence the normal operation of tank roof breathing valve, not require the expenditure of energy, realize that oil gas tentatively reclaims; Particularly when the storage tank internal-external temperature difference is big (like winter), has higher oil gas recovery rate.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1-oil gas inlet, 2-hot side fin, 3-housing, 4-heat pipe, 5-cold junction fin, 6-protective case, 7-oil mist trapping device, 8-oil gas vent.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
This device is installed between the breathing valve and the equipment mouth of pipe of oil product storage tank.Get into housing 3 from 30～50 ℃ oil gas of tank inside volatilization by inlet 1, the condensation that when the hot side fin 2 of superheater tube 4, is cooled reaches oversaturation and forms mist of oil, and the part mist of oil is gathered in hot side fin 2 surfaces and forms oil droplets and fall back in the jar because of self gravitation; Littler mist of oil forms than larger oil droplet further being condensed by oil mist trapping device 7 interceptions of fiber material in the uphill process, finally because of gravity fall, gets back in the jar.After hot side fin 2 absorbs the heat of oil gas, be delivered to cold junction fin 5 rapidly, reject heat in the atmosphere.The protective case 6 on cold junction fin 5 tops is processed by metal gauze, both can protect cold junction fin 5 by the external force damage, does not influence radiating effect again.Lower housing portion directly is connected with the tank top pneumostome through flange.
For the gasoline product storage tank; The oil gas temperature is 40 ℃ in storage tank; Outwards the oil gas volume concentration is 20% during exhaust, and when being 5 ℃, ambient temperature is seen table 1 to the influence of oil gas recovery rate (volume) to the heat transfer temperature difference of heat pipe (condensed temperature of oil gas and ambient temperature poor).
Oil gas recovery rate under the table 1 varying environment temperature
| Ambient temperature/℃ | -20 | -10 | 0 | 5 | 10 | 15 | 20 | 25 |
| Oil gas recovery rate/% | 60 | 43.8 | 26.9 | 19.1 | 12.3 | 6.9 | 3 | 0.7 |
Visible by table 1, when ambient temperature during at 25 ℃, oil gas recovery rate; But the reduction along with ambient temperature is significantly improved, and the percent recovery has reached 26.9% in the time of 0 ℃; In the time of-20 ℃, reached 60%, this is the cause that reduces along with the reduction of temperature owing to the vapor tension of oil product.Therefore, this product is used at the lower northern area of temperature and can be realized better recovering effect.
