A crude gas separation system

Abstract

The invention discloses a crude gas separation system, which comprises a tower body, a gas outlet pipe is connected at the top of the tower body, a crude gas inlet is arranged at the lower part, a tar discharge pipe is connected at the bottom, and a first tar spray pipe is connected at the upper part , the first tar spray pipe is connected with the first tar spray nozzle that extends into the tower body and is located below the gas outlet of the air outlet pipe; the second tar spray pipe is connected in the middle of the tower body, and the second tar spray pipe is connected There is a second tar nozzle extending into the tower body, and the second tar nozzle is located below the first tar nozzle; the length from the first tar nozzle to the top of the tower body is 1 / 10‑2 / 9 of the total length of the tower body; The length from the tar nozzle to the top of the tower is 1 / 2-2 / 3 of the total length of the tower; the length from the crude gas inlet to the top of the tower is 2 / 3-4 / 5 of the total length of the tower. The problem of complex structure, poor dust and tar removal effect, high cost and inconvenient maintenance of the oil-gas separation device in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of coal chemical industry, and in particular relates to a crude gas separation system. Background technique [0002] my country is a country short of oil and gas but relatively rich in coal resources, but coal has not been well utilized as an alternative energy source with abundant reserves. With the rapid development of the economy, China's energy demand has maintained a high-speed growth, and the domestic demand for crude oil has increased year by year. The import volume of crude oil has continuously set new historical records, and the domestic oil production is far from meeting the requirements of the rapid development of the domestic economy. Therefore, vigorously developing the coal chemical industry and replacing petrochemical products with coal chemical products has become an inevitable choice for my country's energy strategy. [0003] At present, pulverized coal carbonization and pyrolysis upgrading has becom...
