Problems solved by technology

[0003] In the 1970s, my country independently developed the rising tube vaporization cooling technology, which was first applied in Shougang and Taiyuan Iron and Steel. Water leakage problem, a serious safety hazard
In the 1980s, Japan developed heat transfer oil jacket technology, which is similar in structure to my country's vaporization cooling technology. pollution problem
At the beginning of this century, my country developed a separate heat pipe technology, but it still has not solved the problem of coking and clogging of raw gas. Long-term use will make the heat transfer effect worse, and seriously affect the service life of the riser. ,increase cost

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] The present invention is a fish scale petal type semi-straight tube coke oven riser waste heat recovery device, such as figure 1 As shown, the fish scale flap type semi-straight tube coke oven riser waste heat recovery device is composed of a cylinder body, a semi-circular casing, a scaled semi-straight tube or overlapping semi-straight tubes, an inlet pipe and an outlet pipe from the inside to the outside. The inner wall of the cylinder is coated with a high-temperature resistant coating, which can effectively alleviate the coking phenomenon during the heat exchange process of the raw gas. The lower end of the cylinder is connected with the roof of the coke oven, from which the raw coal gas enters the riser, passes through the cylinder and enters the gas collection chamber from the upper end of the cylinder. A water inlet is set at the lower end of the semi-an...

Abstract

The invention provides a fish-scale flaky semi-straight-pipe coke oven ascending pipe waste heat recovery apparatus. The fish-scale flaky semi-straight-pipe coke oven ascending pipe waste heat recovery apparatus consists of a barrel, a semi-annular casing pipe, a scale-shaped semi straight pipe or overlapped semi-straight pipe, a water inlet pipe and a water outlet pipe. The inner wall of an ascending pipe is coated with a high-temperature-resisting coating, so that the coking phenomenon of the ascending pipe in the heat exchanging process can be effectively alleviated. By adopting the sale-shaped semi-straight pipe and the overlapped semi-straight pipe, the waste heat of raw coke oven gas can be more efficiently utilized in the heat exchanging process of the raw coke oven gas. The fish-scale flaky semi-straight-pipe coke oven ascending pipe waste heat recovery apparatus is simple in structure, low in production cost, significant in heat exchanging effect and significant to the energyconservation and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of waste heat recovery, in particular to a coke oven riser waste heat recovery device. Background technique [0002] In recent years, with the increasing international competition, the efficient use of energy has become more and more important. Therefore, strengthening energy conservation management and developing and researching waste heat recovery technology are important ways to save energy and reduce consumption in our country. In the coking process, the heat entering the riser from the carbonization chamber accounts for about 36% of the total coking consumption, and the temperature of the high-temperature raw gas entering the riser of the coke oven is about 700°C. Therefore, the research on waste heat recovery technology of high temperature raw gas is particularly important. [0003] In the 1970s, my country independently developed the rising tube vaporization cooling technology, which was first appli...
