Abstract
The utility model provides an analyzed gas cooling device. The existing analyzed gas cooling device has the disadvantage that the analyzed gas with large amount is easy to dissolve in the generated sweating water to make the analytic precision reduced. The cooling device of the utility model comprises a cooling cabinet and a gas cooling tube positioned in the cooling cabinet, wherein the gas cooling tube is divided into two parts of an upstream cooling tube and a downstream cooling tube, the upstream cooling tube is arranged in the cooling cabinet from top to bottom, the downstream cooling tube is arranged in the cooling cabinet from bottom to top, and a thermal protective coating is coated on the upstream cooling tube.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to a kind of device that analytical gas is cooled off.
Background technology
Analytic gas cooling apparatus is used for before gas is analyzed, contained moisture content in the discrete sampling gas to prevent that the detected gas temperature is reduced to dew point and produces dewfall when following, enters measuring instrument, lose gas composition, impact analysis precision and damage instrument.
At present the structure of the analytic gas cooling apparatus that generally uses as shown in Figure 1, it comprises a cool room 10 and is positioned at the cooling coil 11 of cool room 10 that this coil pipe 11 has a gas access 12.Sample gas enters coil pipe 11 from this inlet 12, because coil pipe 11 is arranged in cool room 10, therefore, sample gas is cooled off in coil pipe 11 gradually.Moisture content contained in the gas becomes dew along with the reduction of temperature.Below coil pipe 11, a dew outlet 13 is arranged, dew flows out from this outlet 13, and sample gas then derives from another gas vent 14, enters in the follow-up testing tool and tests.The shortcoming of the gas quench system of this structure is that its cooling procedure is longer, and the gas soluble in water of some in the sample gas can be dissolved in dew in this cooling procedure, cause the component in the sample gas to lose, and causes analysis precision to descend.
The utility model content
Therefore, the purpose of this utility model is to provide a kind of cooling procedure that can accelerate gas, thereby reduces gas dissolving in the analytic gas cooling apparatus of the time of water.
According to above-mentioned purpose, the analytic gas cooling apparatus that the utility model provides, comprise cool room and the gas cooled pipe that is positioned at cool room, it is characterized in that, described gas cooled pipe is divided into two parts: upstream cooling tube and downstream cooling tube, described upstream cooling tube is arranged in the described cool room from top to bottom, and described downstream cooling tube is arranged in the described cool room from bottom to top, coats thermofin outside the cooling tube of described upstream.
Will be about advantage of the present utility model, further feature and effect by following in conjunction with the accompanying drawings concrete
Embodiment is further described.
Accompanying drawing is described
Fig. 1 is the structural representation of the analytic gas cooling apparatus used always;
Fig. 2 is the structural representation of analytic gas cooling apparatus of the present utility model.
Embodiment
As shown in Figure 2, the same with traditional analytic gas cooling apparatus, cooling device of the present utility model also has a cool room 1, and the refrigeration means of this cool room 1 can adopt conventional semiconductor refrigerating or compressor cooling.In this cool room 1, be provided with gas cooled pipe 2.Cooling tube 2 of the present utility model is different with traditional coil pipe, and it is made up of two parts, and first is called upstream cooling tube 21, and its from top to down is arranged in the cool room 1, and the outer thermofin 4 that coats.Second portion is called downstream cooling tube 22, and it is arranged in the cool room 1 from bottom to up, and it is communicated with for 21 times with the upstream cooling tube in the lower end of cool room 1.The upper end of downstream cooling tube 22 is a gas vent 5.
The principle of work of analytic gas cooling apparatus of the present utility model is as follows.
On the other hand, for further accelerating condensing rate, the bore of downstream cooling tube 22 can be arranged to bigger than upstream cooling tube 21.When gas enters into downstream cooling tube 22,, gas flow rate is slowed down like this, help the cooling of gas because internal diameter increases.Generally can adopt teflon to make for the thermofin on the upstream cooling tube 21, and gas cooled pipe 2 can adopt acid-resistant stainless steel to be laminated with pipe.
Claims (3)
