Description
Technical field:
the utility model belongs to the technical field of gas odorization, and particularly relates to an odorizing liquid filling device.
The background technology is as follows:
tetrahydrothiophene with chemical formula C 4 H 8 S is an organic compound or mixture having a strong odor. The natural gas odorizing agent is mainly used as an odorizing agent for fuel gas such as urban gas, liquefied petroleum gas, natural liquefied gas and the like, and when the natural gas odorizing agent is added into the fuel gas in a very low concentration, the fuel gas has a special unpleasant warning odor, so that the leaked fuel gas is detected when the fuel gas reaches 5% of the lower explosion limit or reaches the allowable harmful concentration for human bodies.
In the gas delivery and distribution process, tetrahydrothiophene filling is an important link for guaranteeing safe use of gas. For daily gas supply of more than 400 ten thousand m 3 The injection amount of tetrahydrothiophene is required to be 100kg or more on average per day. At present, tetrahydrothiophene is usually transported by a manufacturer through a special canning vehicle and is directly sent to an odor liquid storage tank through a material pressing device, and tetrahydrothiophene in the odor liquid storage tank is injected into a pipeline. However, in order to cope with situations where canned vehicles cannot be transported in time due to various factors such as weather, logistics and the like, a large amount of tetrahydrothiophene needs to be prepared as a reserve. So as to avoid safety accidents caused by insufficient filling amount of tetrahydrothiophene in the fuel gas.
The reserved tetrahydrothiophene is a special barrel, and an operator at a gate station is required to add the tetrahydrothiophene in the odor liquid barrel into the odor liquid storage tank. For a storage tank for the odor liquid with the volume of 3000kg, when the liquid level is lower than one third to one fourth, about 1000kg of tetrahydrothiophene needs to be timely supplemented, namely the adding amount of the odor liquid is at least more than 5 barrels each time. The original mode of adding tetrahydrothiophene is to insert a gas adding pipe and a liquid outlet pipe into a discharging hole of a odor liquid barrel, then temporarily seal the discharging hole, and make the tetrahydrothiophene in the barrel enter the odor liquid storage tank by nitrogen pressurization. Because the gas pipe and the liquid pipe are arranged side by side and all need to go deep from the discharging hole of the odor liquid barrel, the pipe diameter of the liquid pipe cannot be too thick, the inner diameter is only 6mm, and the flow is smaller; at the same time, the nitrogen pressure of the air source of the pressure device is required to be not more than 30kPa when the nitrogen pressure is added, and if the nitrogen pressure is excessively high, the odor liquid barrel can deform or leak air and liquid, so that potential safety hazards exist. Therefore, the filling time of 190kg of the odor liquid in one barrel is over 180 minutes, the whole process of adding and removing equipment is about 200 minutes, and the filling time of 5 barrels each time is over 16 hours, which takes too long. In addition, the whole process of the odorous liquid adding operation needs to be monitored on site by operators, and the physical performance of the operators is also a test. In addition, tetrahydrothiophene is a hazardous chemical, is volatile, and causes physical discomfort after long-term inhalation, so that the tightness of the device during filling needs to be improved.
The utility model comprises the following steps:
the utility model aims to provide a device for filling odor liquid, which aims to solve the problems.

When in use, nitrogen enters the odor liquid barrel through the nitrogen inlet, so that tetrahydrothiophene in the odor liquid barrel enters the odor liquid storage tank through the liquid discharge pipe under the action of air pressure.
Further, the filter comprises at least one layer of screen. Multiple layers of filter screens with different apertures can be arranged to better filter impurities.
Further, the infusion device also comprises an infusion hose; two ends of the transfusion hose are respectively provided with a pipeline movable joint, and are respectively communicated with the liquid discharge pipe and the liquid inlet pipe of the odor liquid storage tank through the pipeline movable joints; the liquid inlet ball valve is arranged on the liquid inlet pipe of the odor liquid storage tank, and the liquid inlet ball valve can prevent the tetrahydrothiophene in the odor liquid storage tank from continuously flowing in when the liquid level is higher. The pipeline union, the liquid inlet ball valve, the liquid discharge pipe, the infusion hose and the filter are movably connected, such as threaded connection, and the like, so that common equipment in the market can be selected, the sealing performance is not lost, meanwhile, the device can be rapidly assembled and disassembled when in use, the use time is short, and the device is convenient to replace after the use time is long.
Further, the inner diameters of the drain pipe and the infusion hose are not less than 15mm. The original 6mm pipe is replaced by a thick-diameter pipe, so that the speed of the tetrahydrothiophene entering the odor liquid storage tank can be increased.
