Embodiment Construction

[0010] like Figure 1~4 As shown, a dilution cooling device, the dilution cooling device includes a hollow housing 10, the two ends of the housing 10 are respectively provided with an air inlet 11 and an air outlet 12, and the housing 10 is provided with a The housing 10 is provided with a valve plate 33 connected to the driving device, and the driving device drives the valve plate 33 so that the air inlet 11 of the housing 10 is in an open or closed state.

[0011] The air inlet end of the cold air pipe 20 may or may not be provided with a cooling fan. When the air inlet end of the cold air pipe 20 is not provided with a cooling fan, the cold air pipe should be sucked into the casing in the form of jet flow. body 10 to achieve uniform mixing of cold wind and high-temperature gas.

[0012] As a preferred solution of the present invention, the air outlet 12 is provided with an exhaust pipe connected to the exhaust fan, and the air inlet end of the cold air pipe 20 is provided ...

Abstract

The invention relates to a device which can extract high-temperature gas from a high-temperature device and can preliminarily cool the high-temperature gas, particularly relating to a diluting and cooling device. The diluting and cooling device comprises a hollow-shaped shell, wherein two ends of the shell are respectively provided with an air inlet and an air outlet, a cold air pipe which is communicated with an inner cavity of the shell is arranged on the shell, the interior of the shell is provided with a valve plate which is connected with a driving device, and the driving device can drive the valve plate so that the air inlet of the shell can be in an opening or closing state. According to the invention, the cold air pipe which is used to supply cold air is arranged on the shell of the diluting and cooling device, and the high-temperature gas passing through the cavity in the shell can be mixed with the cold air, so the temperature of the mixed gas can be lowered quickly, the shell can be protected from being burnt and damaged, and the service life of the diluting and cooling device can be prolonged.

Description

technical field [0001] The invention relates to a device for extracting high-temperature gas from inside high-temperature equipment and preliminarily cooling the high-temperature gas, in particular to a dilution cooling device. Background technique [0002] At present, when extracting high-temperature gas with a small flow rate from the precalcining kiln, it is difficult to reduce or control the temperature of the extracted gas, so it is easy to cause the extraction device to be blocked and burnt. There is no effective method to reduce the temperature of the extracted gas in the prior art. Withdraw the device. Contents of the invention [0003] The object of the present invention is to provide a dilution cooling device which has a simple structure and can cool the high-temperature gas while extracting the high-temperature gas. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a dilution cooling device, the dilut...
