A naphthalene washing device for primary cooler

Abstract

The invention provides a primary cooler naphthalene-washing device which is applied in the technical field of coke oven parts in iron and steel smelting companies. A primary cooler body (1) of the primary cooler naphthalene-washing device comprises a primary cooler body upper segment (2) and a primary cooler body lower segment (3), wherein a naphthalene-washing slot I (4) and a naphthalene-washing slot II (5) of the primary cooler naphthalene-washing device communicate with an oil supplement component (6); the naphthalene-washing slot I (4) communicates with the primary cooler body lower segment (3); the naphthalene-washing slot II (5) communicates with the primary cooler body upper segment (2). The primary cooler naphthalene-washing device provided by the invention has a simple structure, the temperature of coal gas passing through the primary cooler body can be lowered, the water consumption in a coal gas cooling process is lowered, the production and running cost is lowered, blocking of the primary cooler naphthalene-washing device is reduced, the resistance of the primary cooler body is kept controllable, stable running of the primary cooler naphthalene-washing device is ensured, the cleaning frequency of a primary cooler is lowered, the service life of the device is prolonged, and the filler replacing frequency of a final cooling tower is lowered.

Description

technical field [0001] The invention belongs to the technical field of coke oven components in iron and steel smelting companies, and more specifically relates to a naphthalene washing device for primary coolers. Background technique [0002] The structure of the primary cooler naphthalene washing system in the prior art is mainly that the lower part of the primary cooler body relies on the tank in the tank and the front of the tank to replenish oil, the upper end is sealed with water, and the tar in the primary cooler condensate is mixed to form a naphthalene washing liquid. , the excess part is circumscribed, and the upper section of the primary cooler body and the lower section of the primary cooler body are respectively equipped with a naphthalene washing pump, and its structure is as attached figure 2 mentioned. During the operation, the oil content of the naphthalene washing liquid in the lower stage is uncontrollable, resulting in very poor heat exchange effect of th...

Problems solved by technology

During the operation, the oil content of the naphthalene washing liquid in the lower stage is uncontrollable, resulting in very poor heat exchange effect of the cooling tube in the lower stage of the primary cooler body, which directly leads to the use of a large amount of water in the second stage, but the gas temperature is still high; the resistance of the primary cooler body cannot be controlled, It is often necessary to stop production for cleaning, which has a great impact on the life of the gas system and equipment, and a large amount of naphthalene moves backward, resulting in high resistance to the subsequent system, especially the final cooling tower, which basically needs to be replaced every two years.
