Description

Special infrared detection pool for high-frequency infrared carbon and sulfur analyzer

Technical Field

The utility model relates to an infrared carbon sulphur analytical equipment field, in particular to special infrared detection pond of high-frequency infrared carbon sulphur analysis appearance high low content.

Background

Among the infrared carbon sulphur analysis appearance, the scope that the analysis appearance can measure gas concentration has been decided to the length of air chamber, and the low sample gas of concentration needs longer air chamber, and the high sample gas of concentration needs shorter air chamber, but current same analysis appearance is at the sample in-process, and the range is fixed, can't measure to the sample gas of high concentration and low concentration. In view of this, the present application is specifically made.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a changeable high frequency infrared carbon sulphur analysis appearance of range is special infrared detection pond of high low content to solve the problem that above-mentioned background art provided.

In order to realize the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a special infrared detection pond of high low content of infrared carbon sulfur analysis appearance of high frequency, is including light source, air chamber, light cone and the sensor that is located same straight line, the air chamber is the pipe form, install several printing opacity piece in the air chamber, several printing opacity piece place plane with the air chamber axis is perpendicular, several printing opacity piece will the air chamber is separated for several sub-air chamber, sub-intake pipe and sub-blast pipe, several are installed respectively to the both ends of sub-air chamber lateral wall sub-intake pipe all is connected with the admission valve, and the several admission valve is connected with same main intake pipe, main intake pipe has sample gas to advance pipe and inert gas to advance pipe, several through three way valve connection the sub-blast pipe all is connected with discharge.

Preferably, the lengths of the sub air chambers are different, and the lengths of the sub air chambers are sequentially increased from one end of the air chamber to the other end of the air chamber.

Preferably, the sub-chambers include three sub-chambers, and the intake valve and the exhaust valve are both solenoid valves.

The utility model has the advantages that:

the measuring range is controllable through the plurality of sub-air chambers, the device can be used for measuring high-content or low-content sample gas, the full-range linear calibration can be realized through software control, the carbon and sulfur detection result is more accurate, and inert gas can be introduced before and after use, so that the sample gas in the sub-air chambers can not be influenced by the previous sample gas.

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings that are required to be used in the embodiments will be briefly described below, it should be understood that the following drawings only illustrate some embodiments of the present invention, and therefore should not be considered as limiting the scope, and for those skilled in the art, other related drawings can be obtained according to the drawings without inventive efforts.

Fig. 1 is a schematic structural diagram of the present invention.

The labels in the figure are: 1-light source, 2-light cone, 3-sensor, 4-light-transmitting sheet, 5-sub air chamber, 6-sub air inlet pipe, 7-sub exhaust pipe, 8-main air inlet pipe, 9-sample gas inlet pipe and 10-inert gas inlet pipe.

Detailed Description

The technical solutions in the present embodiments will be clearly and completely described below with reference to the accompanying drawings in the present embodiments, which, however, should not be construed as limiting the present invention to specific embodiments, but are for explanation and understanding only:

as shown in fig. 1, the present embodiment provides a special infrared detection cell for high and low content of a high-frequency infrared carbon and sulfur analyzer, which includes a light source 1, a gas chamber, a light cone 2 and a sensor 3 located on the same straight line, where the light source 1, the light cone 2 and the sensor 3 are all existing infrared detection cells, and this embodiment is not changed.

The air chamber is the pipe form, install several printing opacity piece 4 in the air chamber, several printing opacity piece 4 place plane with the air chamber axis is perpendicular, the light-passing board is also installed at the air chamber both ends, and several printing opacity piece 4 will the air chamber is separated for several sub-air chamber 5, printing opacity piece 4 can be dismantled, is convenient for overhaul the printing opacity piece 4 and change, and the mode of dismantlement is multiple, in this embodiment, the light-passing board outer loop is equipped with the collar, the collar outer wall can the air chamber inner wall joint. The number of the sub-gas chambers 5 is three, the lengths of the sub-gas chambers 5 are different, and the lengths of the sub-gas chambers 5 are sequentially increased from one end of the gas chamber to the other end of the gas chamber. Different sub-air chambers 5 can be used independently or in combination, so that the sum of the sample gases in the sub-air chambers 5 can be provided with various combinations to meet the measurement requirements of different concentrations.

Sub-intake pipe 6 and sub-blast pipe 7, several are installed respectively to the both ends of sub-air chamber 5 lateral wall sub-intake pipe 6 all is connected with the admission valve, and the several admission valve is connected with same main intake pipe 8, main intake pipe 8 has sample gas to advance pipe 9 and inert gas through three way valve connection and advances pipe 10.

Several sub-blast pipe 7 all is connected with discharge valve, and several discharge valve optional connection has same main blast pipe, the gaseous discharge of being convenient for, the admission valve with discharge valve is the solenoid valve. The operator controls the flow of the sample gas entering each sub-gas chamber 5 by controlling the opening and closing degree of each electromagnetic valve, so that the embodiment can meet the measurement of different carbon and sulfur contents, when measuring high-content gas, the sample gas enters the sub-gas chamber 5 with the shortest length by controlling the corresponding valve, and when measuring low-content gas, the sample gas enters all the sub-gas chambers 5 through the electromagnetic valves at the same flow by controlling the corresponding valves. After the experiment is finished, the main air inlet pipe 8 is communicated with the inert gas inlet pipe 10, the inert gas is introduced into each sub-air chamber 5, the sample gas in the sub-air chamber 5 is discharged, and the next experiment is prevented from being influenced.

Each pipeline can be connected with an air pump according to requirements and used as the assistance of air intake or air exhaust.

It is to be understood that the above examples are merely illustrative for clarity of description and are not limiting on the embodiments.
