Description

TECHNICAL FIELD

[0001] The utility model relates to a filter device, especially to a double-inlet horizontal natural gas filter device. BACKGROUND

[0002] Natural gas is a kind of clean energy that is in great demand for users, and almost every family uses it. Natural gas can carry solid dust, ammonium sulfide, condensate oil, water and other liquid impurities in the pipeline transportation process, which can seriously endanger the safe operation of the pipeline and the instrument equipment along the way. Therefore, it is particularly important to equip natural gas filter devices in the pipeline process, especially in the pipeline in the city. The most commonly used in the filter device is the filter core. The traditional filter device needs to be replaced after a period of time due to its simple structure. If the filter core cannot be cleaned and replaced in time, it will seriously affect the passing efficiency and filtering efficiency of natural gas, causing local resistance to soar and passing flow to drop sharply, endangering gas supply safety. However, the traditional filter device needs to replace the filter core frequently, resulting in increased cost. Therefore, how to improve the service life of the filter device, improve the service life, save cost and improve the filtering efficiency is the problem to be solved by the utility model. SUMMARY

[0003] The utility model aims at providing a double-inlet horizontal natural gas filter device for filtering impurities generated in the conveying process from natural gas station to users, realizing clean, clean and impurity-free natural gas in the conveying process of natural gas to users.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is:

[0005] A double-inlet horizontal natural gas filter device, the filter device is mainly composed of a water tank, a water pump, a first ball valve, a second ball valve, an outlet, a filter screen, a shell, a first natural gas inlet, a first S-shaped filter core channel, an arc buffer zone, a second S-shaped filter core channel, a second natural gas inlet, a mixing channel, a Y-shaped sewage discharge channel, a third ball valve and a collection barrel. The left part of the shell is provided with an arc buffer zone, a first S-shaped filter core channel and a second S-shaped filter core channel, the middle part is provided with a first natural gas inlet, a second natural gas inlet and a Y-shaped sewage discharge channel, and the right part is provided with a filter screen and an outlet. The first ball valve is connected with the water pump and the water tank in sequence.

[0006] Further, the first ball valve and the second ball valve are connected in parallel.

[0007] Further, the first natural gas inlet and the second natural gas inlet are symmetrical inlets with the same size.

[0008] Further, the Y-shaped pollution discharge channel adopts a Y-shaped arrangement, and the outlet diameter is 0.8 times the diameter of the second natural gas inlet, so as to directly drop the impurities filtered by the filter screen into the Y-shaped pollution discharge channel, and then discharge the pollution.

[0009] Further, the first S-shaped filter core channel and the second S-shaped filter core channel are channels with the same diameter, and both adopt an S-shaped arrangement, and finally mix in the mixing channel.

[0010] Further, the channels in the first S-shaped filter core channel and the second S-shaped filter core channel are channels formed by the filter core, and the natural gas flows along the channels in an S-shaped manner.

[0011] Further, the mixing channel has a diameter of 1.8 times the diameter of the first S-shaped filter core channel, so as to ensure that there is sufficient gas at the arc-shaped buffer area, and also generate a certain pressure to push the gas into the mixing channel.

[0012] Further, the filter screen is located at the right part of the Y-shaped pollution discharge channel, and the filter screen and the shell are fixed by welding.

[0013] Further, when the filter device is used for a period of time or the filtering effect is poor, the filter device needs to be backwashed to improve the service life, and the backwashing stage is as follows: first, close all the ball valves, open the first ball valve and the water pump, so that the water in the water tank is pressurized by the water pump and then flows into the shell from the outlet, and then flows from right to left in the shell, and then flows from right to left through the filter screen and the mixing channel, and then flows along the opposite directions of the first S-shaped filter core channel and the second S-shaped filter core channel, and finally flows out from the first natural gas inlet and the second natural gas inlet, respectively, with the pressurization of the water pump, the flow rate of the water increases, and the impurities adsorbed on the filter core are carried out by the water flow, thereby achieving the effect of backwashing.

[0014] Further, the first ball valve, the second ball valve, and the third ball valve belong to the prior art, and will not be described here.

[0015] Further, the water pump and the filter core belong to the prior art, and will not be described here.

[0016] Further, the filter screen is composed of multiple layers of cross iron wire screens with a diameter of 1mm, which plays a role in removing impurities, and belongs to the prior art, and will not be described here.

[0017] Compared with the prior art, the utility model has the advantages that (1) through setting back flush stage, back flush is carried out to filter device, improves life; (2) through setting arc buffer area, makes the natural gas that enters into mixed channel have a buffering effect;(3) through setting first S shape filter core channel and second S shape filter core channel, makes the natural gas containing impurity flow in the shell according to S shape;(4) through setting filter screen, the natural gas containing a little impurity is filtered again, improves filtration efficiency;(5) the utility model not only can filter the natural gas containing impurity, but also has good filtration efficiency, and long service life.
