Raw gas separation system

Abstract

The invention discloses a raw gas separation system which comprises a tower body, wherein a gas outlet pipe is connected with the top of the tower body; a raw gas inlet is formed in the lower part of the tower body; a tar discharging pipe is connected with the bottom of the tower body; a first tar spraying pipe is connected with the upper part of the tower body; a first tar nozzle which extends into the tower body and is positioned below the gas outlet of the gas outlet pipe is connected onto the first tar spraying pipe; a second tar spraying pipe is connected with the middle of the tower body; a second tar nozzle which extends into the tower body is connected onto the second tar spraying pipe, and positioned below the first tar nozzle; the ratio of the length between the first tar nozzle and the top of the tower body to the total length of the tower body is (1:10)-(2:9); the ratio of the length between the second tar nozzle and the top of the tower body to the total length of the tower body is (1:2)-(2:3); the ratio of the length between the raw gas inlet and the top of the tower body to the total length of the tower body is (2:3)-(4:5). Through adoption of the raw gas separation system, the problems that the conventional oil-gas separation device is complex in structure, the effect of removing dust and tar is poor, the cost is high, and maintenance is inconvenient can be 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...
