Problems solved by technology

The primary cooler is the key equipment of the coking plant. The primary cooler is used to cool the raw gas. During use, impurities such as coal powder, tar, and naphthalene in the raw gas are deposited on the heat exchange tubes of the primary cooler, which increases the resistance of the primary cooler.

Embodiment

[0022] Such as figure 1 As shown, a primary cooler spraying device includes a spraying pipe 1, a filter 2, an ultrasonic anti-scaling device, a valve 3, a first plate flange 4, a second plate flange 5, and a third plate flange 6 , flange 7, flange cover 12 and short pipe 8.

[0023] The bottom of the spray pipe 1 is provided with a plurality of spray holes 11, and the spray holes 11 are circular holes, oval holes, polygonal holes or holes of irregular shape. From left to right, the spacing of the spraying holes 11 decreases gradually, or the area of ​​the spraying holes 11 gradually increases from left to right, and a small hole 9 is opened on the top of the left end of the spraying pipe 1 . The two flanges 7 are symmetrically fixed on the cylinder body of the primary cooler, the third plate flange 6 is fixed on the right end of the spray pipe 1, the third plate flange 6 and the right end flange 7 are connected by bolts, and then the spraying The pipe 1 is fixed horizontally...

Abstract

The invention relates to the technical field of coking primary cooler cleaning, in particular to a primary cooler spraying device. The device comprises a spraying pipe, a filter and an ultrasonic scale preventing and inhibiting device, the spraying pipe is horizontally and fixedly connected into a primary cooler through a flange, the two ends of the spraying pipe extend out of the primary cooler,and the ultrasonic scale preventing and inhibiting device is fixedly connected to the spraying pipe extending out of the primary cooler. One end of the spraying pipe is connected with a filter which is connected with a spraying liquid main pipe through a connecting pipe, a valve is arranged on the connecting pipe, and the other end of the spraying pipe is connected with a flange cover. The deviceis convenient and fast to mount and dismount, washing liquid is sprayed evenly, scaling in the spraying pipe can be effectively prevented, and particles carried by the washing liquid are prevented from blocking the spraying pipe.

Description

technical field [0001] The invention relates to the technical field of coking primary cooler cleaning, in particular to a primary cooler spraying device. Background technique [0002] The coking chemical industry is an important part of the coal chemical industry, which has made outstanding contributions to my country's economic development. However, with the gradual deepening of the concept of environmental protection, the absorption of toxic and harmful gases by coking plants has attracted more and more attention from the outside world. The primary cooler is the key equipment of the coking plant. The primary cooler is used to cool the raw gas. During use, impurities such as coal powder, tar, and naphthalene in the raw gas are deposited on the heat exchange tubes of the primary cooler, which increases the resistance of the primary cooler. Big. [0003] At present, the method of spraying cleaning liquid is usually used to wash the impurities on the heat exchange tubes. Howe...
