Abstract
A kind of modified liquid collecting well collecting tank of the utility model, including petroleum vapor recovery collecting tank, return-air flexible pipe, hydrops receiving flask, grease receiving flask.Petroleum vapor recovery collecting tank is to be inserted with first gas collection pipe on the middle upper position of sealing structure gas recovery collecting tank, and second gas collection pipe is inserted with by bottom-right location in centre；Return-air flexible pipe connects the top of petroleum vapor recovery collecting tank, and is connected with petroleum vapor recovery collecting tank inner space；Hydrops overflow outlet is additionally provided with petroleum vapor recovery collecting tank on lower position；Hydrops receiving flask, grease receiving flask are respectively arranged on bottom on petroleum vapor recovery collecting tank horizontal level by a fixed mount；Hydrops receiving flask is made up of transparent plastics material, and a bottle cover is set with outside hydrops receiving flask；A lifting rope is provided with bottle cover；Grease receiving flask controls the pipeline of valve to connect with petroleum vapor recovery collecting tank by one with normally closed type；In return-air flexible pipe insertion hydrops receiving flask；Hydrops overflow outlet is also connected by a pipeline with hydrops receiving flask.The utility model, the bottom of petroleum vapor recovery collecting tank is connected by a conduit for being provided with normally closed type blowoff valve with grease receiving flask, and each interface is completely closed, and the residual grease that can prevent blowoff valve from connecting in short tube volatilizes oil gas.
Description
Technical field
The utility model is related to a kind of collecting tank, and specifically a kind of recovery in gas station's secondary oil gas pacify outside liquid collecting well
Complete to install quick cleaning hydrops, personnel need not enter the modified collecting tank of liquid collecting well.
Background technology
According to national requirements, increasing petrol station is mounted with secondary oil gas reclaiming system.In secondary oil gas reclaiming system
In, collecting tank plays a part of to collect hydrops in secondary oil gas recovery tube, and the liquid for ensureing secondary oil gas reclaiming system hinders symbol
Close technical requirements extremely important.For the secondary oil gas reclaiming system for installing vane-type vacuum pump, clear up in collecting tank not in time
Hydrops, it is not single to block secondary oil gas recovery tube, can more damage vavuum pump.
, it is necessary to petrol station employee is periodically into liquid collecting well in the collecting tank system design that current gas station installs, open
Tapping valve collects hydrops.There is problems with this design：
1. petrol station employee cannot observe the height of hydrops in collecting tank, thus not know when hydrops should be cleared up;
2. typically there are 1.5-2 meters of height in liquid collecting shaft bottom from the ground, and petrol station employee falls injured danger into existing during liquid collecting well
Danger；
3. in the operation for excluding hydrops and grease in liquid collecting well, there is part oil vapour to evaporate into liquid collecting well unavoidably, make
Liquid collecting well turns into inflammable and explosive dangerous confined space.Petrol station industry once repeatedly occur operating personnel suck in liquid collecting well be harmful to
The hazard event that gas is fallen in a swoon；
4. in practical operation, the hydrops that we are frequently found in collecting tank is not cleared up in time so that secondary oil
The liquid resistance increase of gas recovery system, or even vane-type vacuum pump is caused because sucking hydrops situation about damaging.
Utility model content
The purpose of this utility model is to overcome the shortcomings of existing for existing collecting tank, there is provided a kind of modified collecting tank.
To achieve the above object, the technical scheme that the utility model is used is：
A kind of modified liquid collecting well collecting tank, including petroleum vapor recovery collecting tank, return-air flexible pipe, hydrops receiving flask, grease
Receiving flask.Petroleum vapor recovery collecting tank is to be inserted with first oil gas on the middle upper position of sealing structure gas recovery collecting tank
Recovery tube, second gas collection pipe is inserted with centre by bottom-right location；Return-air flexible pipe connects the top of petroleum vapor recovery collecting tank
Portion, and be connected with petroleum vapor recovery collecting tank inner space；A hydrops is additionally provided with petroleum vapor recovery collecting tank on lower position to overflow
Flow export；Hydrops receiving flask, grease receiving flask are respectively arranged on bottom in petroleum vapor recovery collecting tank horizontal level by a fixed mount
On；Hydrops receiving flask is made up of transparent plastics material, and a bottle cover is set with outside hydrops receiving flask；One is provided with bottle cover
Lifting rope；Grease receiving flask controls the pipeline of valve to connect with petroleum vapor recovery collecting tank by one with normally closed type；Return-air flexible pipe is inserted
In hydrops receiving flask；Hydrops overflow outlet is also connected by a pipeline with hydrops receiving flask.
During utility model works, when the hydrops in collecting tank is higher by normally opened tapping valve, is flowed into automatically by flexible pipe and accumulated
Liquid receiving flask, gas is back to hydrops collecting tank top by muffler in hydrops receiving flask, and overall process is completely closed, without oil gas
Leakage.Petrol station employee is after well head observes that hydrops reach a certain height in hydrops receiving flask, it is only necessary to pass through lifting rope in well head
Lift and clear up by hydrops receiving flask, without needing to enter in well.After completing hydrops cleaning, hydrops receiving flask is hung back with lifting rope
Original place.
The utility model, the bottom of petroleum vapor recovery collecting tank is provided with the conduit of normally closed type blowoff valve by one and grease is received
Collection bottle is connected, and each interface is completely closed, and the residual grease that can prevent blowoff valve from connecting in short tube volatilizes oil gas.
Brief description of the drawings
Fig. 1 is that the utility model makees structural representation.
Specific embodiment
Embodiment：
As shown in figure 1, the utility model includes that petroleum vapor recovery collecting tank 1, return-air flexible pipe 2, hydrops receiving flask 3, grease are received
Collection bottle 4.Petroleum vapor recovery collecting tank 1 is that one first oil is inserted with the middle upper position of sealing structure gas recovery collecting tank 1
Gas recovery tube 5, second gas collection pipe 6 is inserted with centre by bottom-right location；Return-air flexible pipe 2 connects petroleum vapor recovery collecting tank
1 top, and be connected with the inner space of petroleum vapor recovery collecting tank 1；In petroleum vapor recovery collecting tank 1 one is additionally provided with lower position
Hydrops overflow outlet 8；Hydrops receiving flask 3, grease receiving flask 4 are respectively arranged on bottom in petroleum vapor recovery collecting tank by a fixed mount
On 1 horizontal level；Hydrops receiving flask 3 is made up of transparent plastics material, and is set with a bottle cover 7 outside hydrops receiving flask 3；Bottle cover
A lifting rope is provided with 7；Grease receiving flask 3 is by a pipeline with normally closed type control valve and the phase of petroleum vapor recovery collecting tank 1
Connect；In the insertion hydrops of return-air flexible pipe 2 receiving flask 3；Hydrops overflow outlet 8 is also connected by a pipeline with hydrops receiving flask 3.
