Description
Technical field
This utility model is specifically related to a kind of converter pure dry dust removing gas cooler, belongs to converter gas pure dry dust removing corollary equipment technical field.
Background technology
RECOVERY OF CONVERTER GAS flow process is: steelmaking converter smelting process: molten iron oxygen blast---in molten iron, C is oxidized----generation CO---enters flue gas dust collecting system with flue gas form, after flue gas is purified, and on-line analysis CO%/O2%, as CO < 30%, 02During > 2%, as waste gas spreading; As CO > 30%, 02During < 2%, as coal-gas recovering, send into gas chamber. Gas chamber temperature requirement is 60～70 DEG C, and coal gas is higher than this humidity province, it is necessary to cooling, meets gas chamber temperature requirement.
The converter gas water spray dust collecting process coal gas type of cooling includes:
OG method is sprayed water by two-stage Venturi tube, and 800～1000 DEG C of flue gases directly drop to 60～70 DEG C, containing water and water vapour in coal gas;
LT method passes through spray cooling tower, and by 800～1000 DEG C, flue gas is down to 200～300 DEG C, after electric cleaner purifies, and CO > 30%, 02The coal gas of < 2%, is sent into the gas cooler of water spray by air-introduced machine, by spraying water, by 180 DEG C, gas temperature is down to 60～70 DEG C, sends into gas chamber. Containing water and water vapour in coal gas.
Both of which cannot obtain dry gas, appearance along with pure dry dust removing technology, such as publication number CN102094104B, name is called: the patent of invention of steelmaking converter flue gas by pure dry method dust and Tong Bu energy recovery technique so that the acquisition of converter dry gas become it is achieved that but be because without special corollary equipment, actual production is not effectively applied, especially to there is heat exchange efficiency low for gas cooler, it is impossible to effectively coal gas heat energy is converted to hot water, the problem being used.
Utility model content
Therefore, the purpose of this utility model is to provide a kind of based on pure dry method converter dust-removing, the converter pure dry dust removing gas cooler that heat-transfer surface is big, volume is little, heat exchange efficiency is high, including shell, being provided with the finned tube group of more than a group in described shell, the finned tube of described finned tube group is uprightly arranged, and described finned tube group connects cooling water inlet pipe and outlet pipe, described cover top portion connects aerator by gas inlet pipe, and described outer casing bottom is by coal gas escape pipe connection gas chamber.
Further, described finned tube group is two groups be interconnected, one group of connection cooling water inlet pipe, another group connection outlet pipe.
Further, described cross-sectional outer is rectangle or circle.
The beneficial effects of the utility model are in that: a kind of converter pure dry dust removing gas cooler of the present utility model, owing to being provided with upstanding fins pipe group, heat-transfer surface is big, volume is little, heat exchange efficiency is high, using on the basis of pure dry method converter dust-removing, coal gas of converter is collected as pure dry gas, coal gas heat energy is become hot water simultaneously, recycle. This utility model is suitable for use with the coal gas of converter cooling of pure dry method converter dust-removing technique and uses.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is illustrated:
As shown in Figure 1, a kind of converter pure dry dust removing gas cooler, including shell 1, the finned tube group 2 of more than one group it is provided with in shell 1, the finned tube of finned tube group 2 is uprightly arranged, finned tube group 2 connects cooling water inlet pipe 4 and outlet pipe 3, and shell 1 top connects aerator 6 by gas inlet pipe 5, connects gas chamber 8 by coal gas escape pipe 7 bottom shell 1.
When the pure dry method converter dust-removing technology in adopting background technology, coal gas of converter enters gas cooler through aerator 6, logical cooling water in finned tube group 2, the outer logical coal gas of converter of finned tube group 2, finned tube heat exchange has that heat-transfer surface is big, volume is little, heat exchange efficiency is high, and gas temperature is down to 70 degrees centigrade by 150 degrees Celsius, what now obtain is pure dry gas, pure dry gas stores in gas chamber 8, and the cooling water heating in finned tube group 2, recycles simultaneously.
As preferred embodiment, finned tube group 2 is two groups be interconnected, one group of connection cooling water inlet pipe, another group connection outlet pipe.
As preferred embodiment, shell 1 cross section is rectangle or circle. It is easy to Gas Flow clear and coherent smooth.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from principle described in the utility model; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
