Abstract

PURPOSE:To efficiently sample a large amount of products obtained by combustion reaction and decomposition reaction and steam in air by mounting a metal annular liquid-reception part below a metal cylindrical container with a recessed bottom. CONSTITUTION:When an object to be combusted is placed below the center of the bottom surface of a cylindrical container 1 and combustion is initiated by circulating coolant, combustion products reach the bottom surface of the container 1 while being lifted by ascending current and are condensed since heat is taken away. The generated liquid gathers at the peripheral edge part of the container 1, is dropped at an annular liquid-reception part 2, flows down through a take-out port 6 which is open at the liquid-reception part 2, and is accumulated at a container 7. The temperature of the coolant is measured by a thermometer 8 and the combustion reaction products can be sampled at a constant cooling temperature by adjusting the flow rate of the coolant. Generated substance due to decomposition reaction can also be collected by the similar operation. By loading a cold material such as ice into the container 1 without circulating the coolant, the steam in air can be condensed and gathered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cooling and condensing gaseous substances produced by a combustion reaction and then collecting the gaseous substances.

[0002]

2. Description of the Related Art Heretofore, there has been no dedicated device for collecting gaseous substances generated by combustion reaction.

[0003]

Therefore, in order to collect a gaseous substance generated by a combustion reaction or a decomposition reaction, it is necessary to take what is condensed on the vessel wall of the reaction vessel at an inclination or suck it with a syringe. . Since only a small amount can be collected with each of these methods, it was difficult to utilize them for sufficient research and research.

The present invention has not previously been considered,
It is collected by condensing the gaseous substance produced by the combustion reaction and the decomposition reaction.

[0005]

In order to achieve the above object, in the combustion reaction product sampling apparatus of the present invention, a metallic annular liquid receiving portion 2 is attached below a metallic cylindrical container 1. Has become. Hereinafter, description will be given with reference to the drawings.

In FIGS. 1 and 2, the bottom surface of the cylindrical container 1 is recessed in a dome shape. This is to prevent the heated combustion reaction product from escaping from the bottom surface of the container and to cool it while it is in long contact with the bottom surface.

A cooling water intake port 3 and a cooling water outlet port 4 are provided on the side surface of the cylindrical container. This is for efficiently cooling the combustion reaction product by circulating cooling water in the container.

The columnar container is provided with a grip portion 5 for hanging in the air by a stand or the like. By this, the bottom surface of the container can be fixed at an appropriate position. See FIG.

An annular liquid receiving portion 2 is attached below the peripheral portion of the cylindrical container with an appropriate gap. The combustion reaction product condensed on the bottom surface of the cylindrical container moves to the end of the bottom surface of the container and becomes a drop, which is dropped on the liquid receiving portion. See FIG.

The drops that have fallen on the liquid receiving section 2 flow down from the take-out port 6 which is opened at one place, and are stored in the container 7.

[0011]

In the combustion reaction product sampling device configured as described above, the combustion reaction product is cooled and condensed at the bottom surface of the metal cylindrical container 1 in which the cooling water circulates, and the liquid is received in the annular liquid receiver 2. It is dripped, made to flow down from the outlet 6 and stored in the container 7.

[0012]

[Example] A combustion product is placed below the center of the bottom surface of a cylindrical container. When combustion is started while circulating the cooling water, the combustion products rise in the ascending airflow and reach the bottom surface of the cylindrical container 1, and are deprived of heat and condensed. The generated liquid collects on the peripheral portion of the cylindrical container and drops on the annular liquid receiving portion 2. It flows down from the outlet opened in the liquid receiving portion and is stored in the container 7.

The temperature of the cooling water is measured by an attached thermometer, and the combustion reaction product can be collected at a constant cooling temperature by adjusting the flow rate of the cooling water.

By the same operation, substances produced by the decomposition reaction can be collected.

It is also possible to condense and collect water vapor in the air by putting cold material such as ice inside the container without circulating the cooling water.

[0016]

Since the present invention is configured as described above, it has the following effects.

A large amount of combustion reaction products and decomposition reaction products can be efficiently collected, and samples for various research experiments can be obtained. Similarly, since water vapor in the air can be efficiently obtained in large quantities, it is also useful for environmental research. Also,
It also helps remove harmful substances in the gas.

It is a simple device and is highly producible.
