れる。 FIG. 1 shows a conventional collection device of this kind, in which gas introduced into a collection container 2 disposed in a coagulation collection device main body 1 via a pipe 3 is transferred to a cooling heat exchanger 4.
It is cooled by the heat medium 5 in the collection device main body 1, and is solidified and collected on the inner wall of the collection container 2.

過率が低下し、捕集能力が低下する。この傾向は
特に凝固層６の熱伝導率が小さいとき顕著にな
る。 As the thickness δ of the coagulated layer 6 collected on the inner wall surface of the collection container 2 increases, the gap between the gas in the collection container 2 and the heating medium 5 in the main body 1 increases. The heat transfer rate decreases and the collection ability decreases. This tendency becomes particularly noticeable when the thermal conductivity of the solidified layer 6 is low.

物質の捕集装置に係るものである。 The present invention was proposed in order to eliminate such problems.A vibrator is attached to the outer circumferential surface of a horizontal cylindrical collection container that cools and collects coagulable substances. This invention relates to a coagulable substance collection device characterized in that more vibrators are disposed on the upper surface of the collection container than on the lower surface.

ものである。 In the present invention, as described above, a vibrator is attached to the outer circumferential surface of a horizontal cylindrical collection container that cools and collects coagulable substances. The system vibrates the collection container to cause the solidified material formed on the top surface of the container to fall off when it reaches a certain size. Furthermore, since more of the vibrators are disposed on the upper surface of the horizontal cylindrical collection container than on the lower surface, which is effective for shedding coagulable substances, the effect of shedding the coagulated material produced in the collection container is high. By keeping the upper inner surface of the collection container in a state where there is no coagulum or very little coagulum, the coagulation collection ability can be improved.

の内壁に凝固捕集されるようになつている。 Reference numeral 11 denotes a collection device main body, and 12 a collection container disposed within the main body 11, which is a horizontal cylindrical collection container 1.
2 through the pipe 13 is cooled by the cooling heat exchanger 14.
1 is cooled by the heat medium 15 in the collection container 12.
It is designed to coagulate and collect on the inner wall of the

が得られ、捕集容器の内面上部が、常に凝固体が
ない状態、または非常に少ない状態となる。 By vibrating the collecting container 12 with the vibrator 16, the coagulated material 7 formed on the upper inner surface of the collecting container 12 is caused to fall off after reaching a certain size. At this time, by disposing more vibrators 16 on the upper surface, which is effective for dropping off coagulable substances, than on the lower surface, a high effect of dropping off the coagulable substances is obtained, and the collection container is The upper inner surface is always free of or very little coagulum.

落させることができる。 The excitation acceleration by the vibrator 16 is α=
Assuming that αω 2 sinωt is the mass of the microcoagulates, m is the adhesion force between the coagulates and the inner surface of the collection container 12, then the coagulates are collected by applying an acceleration such that F<maω 2 sinωt. It can be dropped from the inner upper surface of the container 12.
