Problems solved by technology

[0003] Aiming at the disadvantage of low heat exchange efficiency in the current gas horizontal tube primary cooler, the present invention provides a primary cooler, which can reduce the consumption of low-temperature water, and can effectively increase the heat transfer of the heat exchange tubes when the amount of cold water remains unchanged. efficiency, thereby significantly reducing production costs

specific Embodiment approach 1

[0016] A kind of gas horizontal tube primary cooler for coke oven, refer to figure 1 , figure 2 , including a primary cooler housing 1, the housing 1 is fixed with an upper spray pipe 2 and a lower spray pipe 3, the upper spray pipe 2 and the lower spray pipe 3 are in 2 to 8 rows, and the upper spray pipe 2 and the lower spray pipe 5 to 15 sets of heat exchange tubes 6 are respectively installed under the spray pipes 3 , and a broken tower tray 4 is arranged above the spray pipes 3 in the lower section.

[0017] The concrete structure of broken tower tray 4 is, with reference to figure 2 , the tray cap 4-1 is fixed on the hollow tray body 4-3 through the support plate 4-2, and the axis line of the hollow tray body 4-3 coincides with the axis line of the vertical hole of the tray seat 4-4 .

[0018] Preferably, the outer edge of the broken tray 4 is compatible with the inner wall of the primary cooler shell 1, and the tray seat 4-4 can be welded on the inner wall of the sh...

specific Embodiment approach 2

[0022] Now, a mixed liquid spraying device is installed on the top of the primary cooler and the top of the lower section to spray the mixed liquid to clean the tar and naphthalene accumulated on the outer wall of the heat exchange tube. The mixed liquid spraying device is a simple spraying pipe, that is, spraying holes are opened on the pipe wall of the seamless steel pipe. The problem that it exists is that because the mixed liquid contains tar, has a high viscosity, and sometimes contains tar residue particles, the spray hole is very easy to be blocked. To solve the problem that the spray hole is easily blocked and achieve a good spray effect, it is necessary The pump head pressure of the mixed liquid pump is required to be high enough. The side effect of the increase in the pump head pressure is the high energy consumption of the pump. At the same time, the heat exchange tubes in contact with the front of the spray pipe are also prone to wear due to the large impact force. ...

Abstract

The invention provides a coal gas crossing pipe primary cooler for coking furnace, which is a device for cooling coke-oven gas. Due to low heat exchange efficiency for coal gas crossing pipe primary cooler in existence, the provided a coal gas crossing pipe primary cooler includes a primary cooler shell (1), an upper spraying pipe (2) and a lower spraying pipe (3) fixed in the shell (1), and a break tower disc (4) disposed on the lower spraying pipe (3). The break tower disc is disposed on the lower spraying pipe, that is between upper section and lower section of the primary cooler, thereby condensation liquid and spraying liquid for the upper section of the primary cooler can be directly educed not crossing the low section of the primary cooler and not absorbing heat of lower heat exchange pipe. Obviously, the invention decreases heat load of the primary cooler and dosage of water with low temperature, reduces cost, and increases heat exchange efficiency of heat exchange pipe to coal gas.

Description

technical field [0001] The invention belongs to the technical field of coke ovens, and in particular relates to equipment for cooling coke oven gas. Background technique [0002] At present, the cross-tube primary cooler used at home and abroad for the primary cooling of the by-product coke oven gas produced by the coke oven has a rectangular shell section and is divided into upper and lower sections. Many heat exchange tubes are arranged horizontally in the upper and lower sections. The upper section uses high-pressure water First heat exchange is performed on the gas, and the lower section uses low-temperature water to perform secondary heat exchange on the gas; at the top of each section, a mixed liquid spraying device is installed to spray the mixed liquid to clean the tar and naphthalene accumulated on the outer wall of the pipe. Now, the mixed liquid sprayed on the upper section of the horizontal tube primary cooler and the condensate produced by cooling the gas from 8...
