[0028] A filter assembly is arranged in the filter barrel 1, which is used to filter the silt in the mixed hydrocarbon;

[0029] The filter assembly comprises a sieve plate 5 and a sponge layer 6;

[0030] The sieve plate 5 is arranged close to the baffle 3, and when the mixed hydrocarbon enters the filter barrel 1, it changes direction through the baffle 3 and contacts the sieve plate 5;

[0031] The sponge layer 6 is arranged on one side of the sieve plate 5, and the sieve plate 5 is located between the baffle 3 and the sponge layer 6;

[0032] The sieve plate 5 is provided with multiple layers, and the filter holes on the sieve plate 5 are all arranged obliquely upward, and the size of the filter holes on the sieve plate 5 gradually decreases along the direction close to the sponge layer 6;

[0033] The outer layer of the sponge layer 6 is provided with a steel grating framework, a plurality of through holes are arranged on the steel grating framework, and the steel grating framework is connected with the inner wall of the filter barrel 1; the steel grating framework can increase the stability of the sponge layer, so as to avoid that the sponge layer falls off from the filter barrel due to the impact of the mixed hydrocarbon during the filtering process;

[0034] A manhole 7, a gas phase pipe 8 and a liquid level meter port 9 are arranged on the top of the filter barrel 1, and a water phase discharge pipe 10 is arranged at the bottom of the filter barrel 1;

[0038] The main application point of the application is that the flow direction of the mixed hydrocarbon into the filtering barrel is changed by the baffle, so that after the mixed hydrocarbon enters the filtering barrel, the large-diameter sand in the mixed hydrocarbon touches and flows downward to the sieve plate with a porous structure by the baffle with an inclination of 45 degrees, the large-diameter sand in the mixed hydrocarbon is filtered by the filter holes on the sieve plate, then the mixed hydrocarbon passes through the sieve plate and passes through the sponge layer with high density, in the process, the sponge layer filters the small-diameter sand, and the mixed hydrocarbon enters the mixed hydrocarbon light phase side after passing through the partition plate, so that the problem that the sand accumulates on the tray and causes the device to stop regularly is solved. The free water in the mixed hydrocarbon flows to the sieve plate with the mixed hydrocarbon under the action of the inlet baffle, the small liquid drops collide under the action of the porous plate, and the small liquid drops combine into large liquid drops, the density of water is 1000 kg / m3, the density of the mixed hydrocarbon is 0.53 kg / m3, then the large liquid drops sink to the bottom of the filtering barrel under the action of gravity, so that the effect that the water and the mixed hydrocarbon are completely separated is achieved.
