Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the description of the embodiments, the same components are denoted by the same reference numerals.

FIG. 1 is a system structural view of a chemical reaction system according to an embodiment of the present invention, and FIG. 2 is a control block diagram of FIG.

Referring to these drawings, the chemical reaction system according to the present embodiment includes a reaction gas supply unit 101 for supplying a reaction gas, a carrier gas supply unit 102 for supplying a carrier gas, a chemical reactor 120 A collector 104 for collecting the product produced as a result of the chemical reaction in the chemical reactor 120, and a chlorine collector 105 for collecting excess chlorine gas discharged from the chemical reactor 120.

The reaction gas supply unit 101 may be connected to the chemical reactor 120 and a reaction gas supply amount control valve 106 may be provided on the line L1 to control the supply amount of the reaction gas. The reactive gas supply unit 101 may be, for example, a chlorine gas supply unit. That is, it is necessary to supply a chlorine gas to the reaction gas in order to produce a variety of silicon chloride compounds, particularly HCDS (Si 2 Cl 6 ) used as a semiconductor material, as in the reaction scheme 1.

The carrier gas supply unit 102 may be connected to the chemical reactor 120 and the carrier gas supply amount control valve 107 and the cooler 108 may be provided on the line L2 connecting them. The carrier gas serves to regulate the temperature in the chemical reactor 120 or smoothly transfer the reaction gas supplied into the chemical reactor 120. For example, an inert nitrogen gas may be used as the carrier gas.

In the case where the reaction in the chemical reactor 120 is an exothermic reaction, for example, in the process of reacting calcium silicate, which is a reactant, with the reactive gas chlorine gas in the reaction scheme 1, excessive heat may be generated. Heat generation can be controlled. That is, by providing the cooler 108 between the carrier gas supply unit 102 and the reactor 120, it is possible to inject the carrier gas that has been cooled at a low temperature into the reactor 120 to easily control the temperature in the reactor 120 have.

The reactor 120 connected to the reaction gas supply unit 101 and the carrier gas supply unit 102 is a place where a chemical reaction actually proceeds to obtain a desired product. The chemical reactor will be described in more detail below.

The product produced in the reactor 120 is discharged in a gaseous state and is collected in the liquid state in the collector 104 via the cooler 103. For example, in the reaction formula 1, the silicon chloride compound produced by the reaction of calcium silicide and chlorine gas in the reactor 120 is vaporized and discharged to the gaseous state because the temperature in the reactor is higher than the boiling point of the silicon chloride compound. And is collected in the collecting device 104 in a liquid state while being liquefied through the cooler 103.

In addition, the chlorine gas as a reactor together with the generated gas can also be discharged from the reactor 120, which is not liquefied even if it passes through the cooler 103 because the liquefaction point is much lower than the silicon chloride water. Thus, this excess chlorine gas is collected in a separate surplus chlorine collector 105 and then vented after the purification treatment.

Although the reaction gas supply unit 101 and the carrier gas supply unit 102 are schematically shown in FIG. 1, various gauges, safety devices, and the like may be added thereto.

In addition, as already described, the supply amount of chlorine as the reactor and the nitrogen as the carrier gas are respectively regulated by the regulating valves 106 and 107, and these regulating valves 106 and 107 are all controlled by the controller .

For example, the controller 110 can control the operation of the chlorine supply control valve 106 and the nitrogen supply control valve 107, as shown in FIG. Since the operation of the chlorine feed rate control valve 106 and the nitrogen feed rate control valve 107 is controlled by the controller 110, the chlorine feed rate control valve 106 and the nitrogen feed rate control valve 107 are controlled by the solenoid valve And the like.

The controller 110 that performs such a role may include a central processing unit 111, a memory 112, a memory 112, and a support circuit 113.

The central processing unit 111 may be one of various computer processors that can be industrially applied to control the operation of the chlorine supply regulating valve 106 and the nitrogen supply regulating valve 107 in the present embodiment.

The memory 112 (MEMORY) is connected to the central processing unit 111. The memory 112 may be a computer readable recording medium and may be located locally or remotely and may be any of various types of storage devices such as, for example, a random access memory (RAM), a ROM, a floppy disk, At least one or more memories.

The support circuit 113 (SUPPORT CIRCUIT) is coupled with the central processing unit 111 to support the typical operation of the processor. Such a support circuit 113 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

In this embodiment, the controller 110 controls the operation of the chlorine supply regulating valve 106 and the nitrogen supply regulating valve 107. At this time, a series of processes or the like in which the controller 110 controls the operation of the chlorine supply control valve 106 and the nitrogen supply control valve 107 may be stored in the memory 112. Typically, a software routine may be stored in the memory 112. The software routines may also be stored or executed by other central processing units (not shown).

Hereinafter, the chemical reactor 120 in which the chemical reaction actually proceeds will be described in more detail with reference to FIG. 3 to FIG.

FIG. 3 is a perspective view of a chemical reactor according to an embodiment of the present invention, FIG. 4 is a view showing a door opened in FIG. 3, FIG. 5 is an exploded view of FIG. Fig. 9 is a perspective view of the basket, Fig. 7 is a partial exploded view of Fig. 6, Fig. 8 is a rear perspective view of the basket, Fig. 9 is a sectional structure view of the basket, Fig. 10 is a sectional view taken along line AA of Fig. Fig.

First, the chemical reactor 120 will be described with reference to FIGS. 3 to 6. FIG.

Referring to these drawings, the reactor 120 includes a reactor case 130, a reaction housing 140, and a door 150, and a basket is detachably coupled to the reaction housing 140.

The reactor housing 130 is a case for housing the reaction housing 140, and the reaction housing 140 can be housed in the reactor housing 130 in a drawable manner. Such a drawer type cabinet structure has an advantage that the installation and maintenance are easy and the replacement operation is also convenient.

A leg 132 is provided in the reactor case 130, and the reactor can be safely supported on the ground by providing the legs. Unlike the figure, when the leg 132 is equipped with a wheel, there is an advantage that the position of the reactor case 130 is easily moved.

The reaction housing 140 provides a place where a chemical reaction takes place and a basket in which a reaction material for a chemical reaction is placed is detachably coupled to the reaction housing 140. The door 150 is connected to the front surface of the reaction housing 140 And serves to open and close the opening.

The reaction housing 140, the door 150 and the basket 160 may form a single unit set as shown in FIG. 6, which is formed in the reactor case 130 along the height direction The shelf 131 may be detachably coupled to the shelf 131.

3 to 5, there is shown a reactor case 130 in which eight shelves 131 are provided. In this case, as shown in FIG. 6 having the reaction housing 140, the door 150 and the basket 160 A total of eight unit sets can also be used. Of course, not all of the eight unit sets need to be used, and can be selectively used according to process conditions.

For reference, the structure and shape of the chemical reactor 120 shown in the drawings are only one example. Therefore, the scope of the present invention is not limited to the structure and the shape of the drawings.

Hereinafter, the reaction housing 140, the door and the basket 160 will be described in more detail with reference to FIGS. 6 to 11. FIG.

First, the basket 160 will be described with reference to the basket 160. The basket 160 can be slidably moved into and out of the reaction housing 140. At this time, it is preferable that the basket 160 is slidably coupled to the reaction housing 140 so as to prevent the reaction gas and the generation gas from escaping between the reaction housing 140 and the basket 160.

The basket 160 may be in various forms that can slide and move in close contact with the reaction housing 140. For example, the basket 160 may be in the shape of a rectangular parallelepiped with open upper and lower portions. Such a reactant is placed on a pore structure provided inside or below the basket.

The pore structure may be a fine mesh structure in which a hole having a diameter capable of allowing a reactive gas to pass therethrough is formed without allowing the reaction material placed at the top to pass downward. For example, the pore structure may be a sintered filter having a hole having a diameter of about 1-10 탆.

The pore structure may form the lower surface of the basket 160 according to the shape of the basket 160 or may be provided so as to be in close contact with the inner surface of the basket 160 inside the basket 160. 6 to 11 show a pore structure inside the upper and lower open basket 160. However, the pore structure may have a structure in which the reaction gas flows from the lower part of the pore structure to the upper part of the basket 160, It need only be provided at a specific position.

Reactants are deposited on the pore structure. For example, in the case of Reaction 1, a reactive material such as calcium silicate may be placed on the pore structure.

When the reaction material is placed on the pore structure and a reaction gas such as chlorine is introduced from the bottom of the pore structure, the chemical reaction time can be shortened, And zero of the unreacted material can be realized.

A reaction gas inlet 160a may be formed in the basket 160 so that the reactive gas can be easily introduced into the pore structure. The reactant gas inlet 160a is preferably formed at least at the bottom of the pore structure, and may be in the form of a hemispherical hole or a circular hole, and a plurality of reactant gas inlets 160a may be formed.

In one embodiment, the reaction gas inlet 160a is formed on only one wall of the basket 160, but the reaction gas inlet 160a may be formed on both walls of the basket 160. When the reaction gas inlet ports 160a are formed on both side walls of the basket 160, the basket 160 can be inserted back and forth.

Meanwhile, it is preferable that the basket 160 has a pore structure at its bottom and an open top. By opening the top as described above, the reaction gas can be supplied not only at the bottom but also at the bottom of the pore structure, The reaction yield can be improved and zeroization of unreacted materials can be realized.

Next, the reaction housing 140 will be described.

The reaction housing 140 provides a place where a chemical reaction takes place and the reaction housing 140 can be made of a box-type structure in which an arc-shaped space portion 146 is formed at the rear. Therefore, the basket 160 can slide into and out of the reaction housing 140.

The arc-shaped space portion 146 formed in the inner side of the reaction housing 140 forms a space in which the gaseous product and some reaction gases generated as a result of the chemical reaction in the reaction housing 140 flow. The gaseous product and some of the reactive gas may be directed from the system of FIG. 1 to the cooler 103 through gas outlets 146a formed on the rear surface of the arc-shaped space portion 146 and the like. At this time, since the arc-shaped space portion 146 has an arc shape, it is possible to guide the gas to flow well without vortex.

A stopper 147 is provided in the boundary region of the arc-shaped space portion 146 of the reaction housing 140 to restrict the entry position of the basket 160. That is, the basket 160 can only enter the reaction housing 140 up to the stopper 147.

A reaction gas is introduced into the reactor housing 140 through a lower gas inlet port (not shown) so that the reactant gas and the carrier gas introduced through the reaction housing 140 are introduced into the pore structure from the upper or lower side of the pore structure, 141 and an upper gas inlet 142 are provided.

10, the lower gas inlet 141 is disposed below the pore structure with the pore structure in the basket 160 as a reference position, and serves to inject the reaction gas and the carrier gas into the lower portion of the pore structure And the upper gas inlet 142 is disposed above the pore structure with the pore structure in the basket 160 as a reference position and serves to inject the reaction gas and the carrier gas into the upper portion of the pore structure.

When both the lower gas inlet 141 and the upper gas inlet 142 are formed on the side of the reaction housing 140 as in the present embodiment, the reaction gas and the carrier gas can be supplied at the upper and lower portions of the pore structure, The reaction time can be shortened and the reaction heat can be easily suppressed. In particular, the yield can be kept constant, and the zero of the unreacted material can be realized.

The lower gas inlet 141 and the upper gas inlet 142 may be provided in plural numbers. A spare gas inlet 143 may be further provided in the periphery of the lower gas inlet 141 and the upper gas inlet 142.

Pressure gauge mounts 144 and 145 may be provided around the lower gas inlet 141 and the upper gas inlet 142. The pressure gauge mounts 144 and 145 are provided on the side of the reaction housing 140 and serve as a place for mounting a pressure gauge (not shown) for measuring the pressure in the reaction housing 140 during a chemical reaction.

Since the lower gas inlet 141 and the upper gas inlet 142 are provided on the side of the reaction housing 140 and the gas is supplied from the lower part and the upper part of the reaction housing 140, It is necessary to separately measure the lower side pressure and the upper side pressure of the upper and lower sides 140, 140, respectively. Accordingly, the pressure gauge mounts 144 and 145 include a lower pressure gauge mounting hole 144 disposed below the pore structure with the pore structure in the basket 160 as a reference position, a pore structure body in the basket 160 as a reference position And an upper pressure gauge mount 145 disposed above the pore structure.

A temperature sensor for measuring the temperature inside the reaction housing 140 may be provided in the reaction housing 140. The temperature sensor at this time may also be disposed inside the reaction chamber 140 in the same manner as the pressure gauge mounts 144 and 145 The pores may be arranged below the pore structure with the pore structure as a reference position to measure the lower temperature and with the pore structure in the basket 160 as a reference position, .

As shown in FIG. 10, an insulator 181 may be provided on the upper part of the reaction housing 140. The insulator 181 is provided for isolation from neighboring structures.

A heat insulating case 182 having a plate heater 183 is disposed under the reaction housing 140. The temperature suitable for the chemical reaction can be maintained by the action of the plate heater 183.

An O-ring is provided between the door 150 and the reaction housing 140 so that a reaction gas, a carrier gas, and a reaction gas are supplied between the door 150 and the reaction housing 140 during the chemical reaction in the chemical reactor 120. [ And the generation gas or the like can be prevented from leaking.

The basket 160 in which the pores are installed at a position spaced from the bottom of the reaction housing 140 is inserted into the reaction housing 140 and the door 150 is closed, When the gas and the carrier gas are injected, the reaction gas and the carrier gas are introduced into the lower part of the basket 160 through the upper and lower gas inlet ports 141 of the reaction housing and the reaction gas inlet port 160a of the reaction container, That is, the chemical reaction with the reactant in the upward movement, thereby obtaining various gaseous products. The desired products can be obtained by cooling and collecting these various products.

According to an embodiment of the present invention, chlorine as a reactor and nitrogen as a carrier gas are introduced into a basket containing a reaction material so that various kinds of silicon chloride products can be obtained by chemical reaction. However, , The reaction time can be shortened and the reaction heat can be easily controlled. In particular, the yield can be kept constant and the zero of the unreacted material can be realized.

Fig. 12 is a partially exploded view of a chemical reactor according to another embodiment of the present invention, Fig. 13 is a sectional view of the basket, Fig. 14 is a longitudinal section cutaway perspective view of the reaction housing, Fig. 15 is a cross section cutaway perspective view of the reaction housing, 17 is a cross-sectional view of the chemical reactor.

When the basket 260 having the pore structure is inserted into the reaction housing 240 and the door 250 is closed and the reaction gas is introduced into the reaction housing 240 to advance the chemical reaction, It is preferable that a gap is not formed at a portion where the basket 250 and the basket 260 are in contact with each other, that is, the contact side. This is because when the gap between the reaction housing 240, the door 250 and the basket 260, that is, the contact side, is generated, the reaction gas or the like can be discharged through the gap as it is, This is because the reactants may increase.

Accordingly, it is required to allow the sliding movement of the basket 260 to the reaction housing 240 but to prevent the gap between the reaction housing 240, the door 250 and the basket 260 from being generated , And the sliding movement gap generating and stopping unit 270 plays a role in this embodiment.

In other words, the slidable gap generating and stopping portion 270 is provided at a portion where the reaction housing 240, the door 250 and the basket 260 are in contact with each other, while permitting the sliding movement of the basket 260, 240, the door 250, and the basket 260, as shown in FIG.

In this embodiment, the sliding movement gap generating and stopping unit 270 is implemented by forming a certain structure on the outer surface of the basket 260, the inner surface of the reaction housing 240, and the inner surface of the door 250.

The slidable movement gap generating and stopping unit 270 includes first to fourth inclined skirts 260a to 260d formed along the circumferential direction of the basket 260 and a first to fourth inclined skirts 260a to 260d formed along the inner circumferential direction of the reaction housing 240 Side skirt support portions 240a to 240c that are in contact with the first to third inclined skirt portions 260a to 260c in a shape fitting manner and a fourth inclined-like skirt support portion 240a to 240c formed on the inner surface of the door 250, And a door-side skirt support portion 250a that is shaped and contacted with the skirt portion 260d.

Since the basket 260 is a rectangular box-shaped structure, four first to fourth slanted skirts 260a to 260d may be formed along the circumferential direction of the basket 260. At this time, the angles of the first to fourth inclined skirts 260a to 260d may be determined in the range of 30 ° to 70 °.

The first to third inclined skirts 260a to 260c of the first to fourth inclined skirts 260a to 260d are formed in the first to third housings 260a to 260d formed along the inner surface of the reaction housing 240, The fourth inclined skirt portion 260d can be brought into close contact with the door side skirt support portion 250a formed on the inner surface of the door 250 without a gap being formed in the side skirt support portions 240a to 240c, ).

Therefore, the first to third housing side skirt support parts 240a to 240c and the door side skirt support part 250a should be machined at the same angle as the first to fourth inclined skirt parts 260a to 260d.

A partition wall 247 is formed in the boundary region of the arc-shaped space 246 so that the third housing-side skirt support portion 240c is formed. The upper end of the partition wall 247 is connected to the first and second housing- (260a) and (260b), respectively.

As a result, the first to fourth slanted skirts 260a to 260d are formed on the basket 260, and the first to third housing skirt supports 240a to 240c are formed on the reaction housing 240, And the door 250 is provided with the door side skirt support portion 250a so as to permit the sliding movement of the basket 260 while eliminating the gap between them to prevent the chlorine and nitrogen from escaping to the outside It is. Accordingly, not only the yield can be kept constant but also zero of the unreacted material can be realized.

When the sliding movement-use gap generating and stopping unit 270 having such a structure is applied, the manufacturing period is short, and it is very economical, and particularly, the sealing is excellent.

18, the arc-shaped basket may be provided with a pore structure inside the arc-shaped basket having the lower end portion 361 of the side wall 361 in an arc shape and the upper and lower openings.

Referring to FIG. 19, the boat-shaped basket 460 has a shape in which the side wall 461 is narrowed toward the bottom, and a pore structure may be provided therein. 19, the pore structure is spaced apart from the lower end of the basket 460, but when the lower portion of the basket 460 is spaced apart from the bottom of the reaction housing, the pore structure may form a lower surface of the basket 460 .

20, the uneven basket 560 is provided with a concave-convex type rail block 562 on the side wall 561 and the pore structure is disposed apart from the lower end of the basket 560. However, The pouch structure may be provided to form the lower surface of the basket 560 when the lower portion of the basket 560 is installed to be spaced from the bottom of the reaction housing.

When such baskets 360, 460 and 560 are applied, the reaction housing (not shown) must also have a shape corresponding to the baskets 360, 460 and 560, and in this case it is possible to prevent the generation of gaps between the baskets 360, .

It is expected that the basket 360, 460, and 560 may take a longer time to manufacture the basket 460, the arc-shaped basket 360, and the concave-and-convex basket 560, .

Although not shown in the drawing, a basket (not shown) may be formed in a rectangular shape and a protrusion may be formed at least at four corners of the bottom of the reaction housing (not shown) to allow the basket to be seated on the protrusion. It is also possible to apply a structure in which a rectangular bracing bar is formed in a specific place (front, middle, rear) and the basket is mounted thereon, instead of forming the protruded rim (skirt) continuously. It should be within the scope of the invention.
