摘要： PROBLEM TO BE SOLVED: To prevent explosion accidents by avoiding polymerization at the time of crystallization of polymerizable compounds such as acrylic acid, methacrylic acid, etc. SOLUTION: In the case of melting of acrylic acid crystal, a polymerization inhibitor is added to a refined melting liquid with the same purity as the crystal and at the same time the refined melting liquid is heated and circulated and supplied to the crystal. In the case of crystallization in multi-stages wherein a crystal melting liquid in a storage tank V-1 is stored in a storage tank V-2 and the melting liquid in the storage tank V-2 and a mother liquid are stored respectively in a next storage tanks V-3 and the prior storage tank V-1, the polymerization inhibitor is previously added, for example, to the storage tank V-3 in the final stage and a product storage tank V-4. Consequently, the polymerization inhibitor can be added automatically to the storage tanks in lower stage (stages where refining degree is low) sides.

摘要： PURPOSE: To provide a crystallizer and a crystallizing method for performing mass production of crystalline materials of high purity while crystals are prevented from being dropped off. CONSTITUTION: A plate 2 in which a projection part 3 is arranged on one side thereof is vertically arranged, and a liquid raw material is caused to flow down on one side 22 of the plate, and also on the other side thereof, a refrigerant of temperature not more than the freezing point of crystals is caused to flow down in the form of a thin film, allowing the crystals to be grown with a part of the crystal layer on one side 22 of the plate 2 being held on the projection part 3. Next, on the other side 23 of the plate, a heating medium of temperature above the freezing point of the crystals is caused to flow down in the form of a thin film, allowing the crystals to be melted and recovered. Here since a part of supporting force of the crystal layer is borne by the projection part 3, the crystal layer is prevented from being peeled from the plate.

摘要： PURPOSE:To produce a large amt. of crystals with high purity by means of a simple and large apparatus by a method wherein a liq. raw material is made to flow down on one face side of a vertical plate and a cooling medium with a temp. being at least m.p. of this liq. raw material is made to flow down on another face side to deposit crystals and then, a heating medium is made to flow down. CONSTITUTION:A base plate 11 for adhesion of crystals is stood up vertically and a liq. raw material 14 contg. crystallizable component is fed circulatedly on one face side 12 of this plate and is made to flow down into a thin film. In addition, a cooling medium 15 with a temp. being at least m.p. of the liq. raw material 14 is made to flow down on another face side 13 of the plate 11 to deposit crystals on one face side 12 of the plate 11 and the crystal layer is gradually grown. When the thickness of the crystal layer reaches a specified value, uncrystallized remaining liq. is extracted and a heating medium with a temp. being at least m.p. of the crystals constituting the crystal layer is made to flow down into a thin film on another face side 13 of the plate 11 to melt gradually the crystals, which are recovered below. Treatment like this is performed by multi-stages.

摘要： PURPOSE:To prevent a hopper from a bridging phenomenon of dumped substances for delivering stably a constant amount of the substances by attaching a screw to the bottom of a hopper having an upward flaring section and constituting a flapper pivotably suspended parallel to the screw in the approximately central portion of the hopper. CONSTITUTION:When substances 2 like sludge are dumped into a hopper body 11 a flapper 22 is somewhat inclined to the vertical line about a horizontal axis 21 by the substances dumped uniformly left and right of the flapper. Under this condition, a drive unit is driven to rotate screws 12, 13 and deliver the dumped substances 2 in the lower portion of the hopper so that a cavity is formed near the screws 12, 13 (bridging phenomenon). Then, the substance at one side of the flapper 22 making an obtuse angle with the horizontal line slips down by its own weight to be delivered by the screws 12, 13, and next the substance at the acute angle side drops to swing the flapper 22 in the opposite direction, and is delivered by the screws 12, 13. Such operation is repeated so that all substances 2 are smoothly delivered without making up any bridges.
摘要翻译：目的：为了防止料斗脱落物质的桥接现象，通过将螺钉连接到具有向上的扩口部分的料斗的底部并且构成在大致上平行于螺杆可枢转地悬挂的挡板的情况下稳定地输送恒定量的物质料斗的中心部分。构成：当像污泥这样的物质2被倾倒到料斗本体11中时，挡板22相对于横向轴线21的垂直线稍微倾斜，这些物质被挡板的左右均匀地倾倒。在这种情况下，驱动单元被驱动以旋转螺钉12,13，并将倾倒的物质2输送到料斗的下部，使得在螺钉12,13附近形成空腔（桥接现象）。然后，与水平线成钝角的挡板22的一侧的物质通过其自身的重量而下降，由螺钉12,13输送，接下来，锐角侧的物质下降以使挡板22摆动在相反方向上，并由螺钉12,13输送。这样的操作被重复，使得所有物质2均可顺利地输送而不需要任何桥梁。

摘要： PURPOSE:To lower thermal stress by installing an intermediate tube sheet to divide a container and installing a heat insulating plate in one side of the intermediate tube sheet. CONSTITUTION:At least one intermediate tube sheet 3 is installed to divide a container into a high temperature chamber 1A and a low temperature chamber 1B. A plurality of heat exchanger tubes 2 which work as reaction tubes and penetrate the intermediate tube sheet are installed. Spacers 5 are installed between the intermediate tube sheet 3 and a heat insulating plate and between each heat insulating plate if there are a plurality of heat insulating plates so as to form a liquid gathering place 6 so that almost all heating medium does not flow. By this way, heat transfer from the high temperature chamber to the low temperature changer is lowered, resulting in low energy loss.
