A powder and particle blocking device that can smoothly perform the connection between the blocking tube and the transfer tube without blocking. Fig. 2 is an explanatory diagram of the overall structure of powder and granular materials such as waste plastic applied to a raw fuel to a blast furnace. Fig. 3 is an explanatory diagram of a main part of Fig. 2 / a front view of the main part. In the figure, 3 is a blowing funnel, u is a mechanical feeding device that quantitatively blocks the powder and granules from the second funnel 3, and 31 is a blockage of the powder introduction and conveying pipe blocked by the 31 type feeding device. 'Pipe' 3 is installed in the blocking pipe 31 to accelerate the speed of the powder and granules, such as air and other gas accelerating nozzles, 53 is provided at the end of the conveying pipe 10 to the top]. spray gun.

The upper end side of the blocking pipe 31 is connected to the side of the mechanical feed 11 and has a vertical portion 31a extending approximately vertically, and is connected to the vertical portion 31 and is connected to the staggered portion. 31 a is formed by bending at a 45 ° angle in the forward direction (conveying direction) and is connected to the inclined portion 31 b of the conveying pipe 10. f The shape of the blocking tube 31 is gradually deformed from the upper end to the lower end, and the cross-sectional area is approximately constant. When the cross-sectional area is small, the powder and granules tend to be clogged. On the other hand, when the cross-sectional area is too large, the powder flow velocity decreases. In order to eliminate the above problems, the cross-sectional area is kept constant. The side shape of the blocking tube 31 is provided with a taper on one side only.

With a taper, the valley is prone to produce shed materials caused by the 禊 -shaped effect. Only a taper can avoid such problems. The sag portion 31a of the blocking tube 31 should be as long as possible in order to maximize the falling speed of the particles. It will be described later, and the inclined portion 3 lb can be set to the shortest length β as long as the length required for acceleration is guaranteed.

Figure 5 is for: Γί = ㈣3 uses the same components for the same parts: the material circle represents the particles of the powder and granules, and hi represents the vertical direction from the mechanical type i, the lower part of the device to the bent part of the blocking tube 31 The distance indicates the vertical distance from the bent portion of the blocking tube 31 to the transfer tube 10. The degree of catch of the powder and particles freely falling from the mechanical feeding device u in the bending portion is \ (vertical downward), and the acceleration gas is ejected by the acceleration nozzle 33 to cause the powder and particles to change directions in the direction of the inclined portion 31b. At the same time, the speed is increased to V2. Then, the direction of the powder and granules is changed to the blowing direction by blowing air into the conveying pipe, and the speed reaches%. At this time, the speed of the blowing air is represented by VG, so that the partial speed v0 of the conveying direction (horizontal direction) of the air speed 乂 2 which changes the direction of the accelerated gas and increases the speed is the same as the speed νΰ of the blowing air. In this way, the powder and granules can be smoothly carried away by the carrier gas at the above-mentioned connection, and the amount of air to be sprayed is limited to the minimum value β. As described above, in the present embodiment, it is provided in the middle of the blocking tube 31 The inclined portion 31 b 'sprays accelerated gas on the inclined portion 3 1 b to turn and increase the speed of the powder and particles, and makes the partial velocity in the horizontal direction equal to the speed VQ of the air blowing. Therefore, the powder and particles can smoothly merge and prevent Occurrence of blocking phenomenon> In the above example, the inclination angle is set to 45 ° vertically downward.

The best shape effect "By detecting the pressure in the delivery pipe and transferring it to a storage capacity that is higher than the above, the storage container can be stored. This can continuously block and block the connection part of the vertical part, by tilting the gas nozzle. When the direction is blocked, the tube is not limited to this. As shown in FIG. 6, the tilt angle is set to 60. Angles are also available. However, at this time, the amount of exchange with the angle 4 5 e increases, and the amount of accelerated gas or flow rate needs to be increased. A smooth confluence can be achieved with 嗔. The angle is much smaller than 45 °. It is better to control the convergence angle at 40 ° because it hinders the smoothness of the convergence area. The tilt angle should be 40 β ~ 60. angle. State 1 has the structure described above, so it has the following pressure in the delivery tube pressure tube in the storage container. The pressure in the pressure tube in the delivery tube is reliable and stable. The powder and granules are broken by a blowing funnel in the storage silo. At the same time when it is set to the lead, the vertical speed of the powder along the inclined structure can be set slightly higher than the detection force of the pressure of the conveying pipe. The vertical tilting body is vertically set by the above. The pressure measurement method of the container being blocked by the air flow will press the above-mentioned storage materials arranged in the powder and granules to achieve the extended portion to spray the gas in the moving direction, and the gas transfer pipe plug will be tested by the strength tester and adjusted according to the force of the storage container. The blocking of the transfer tube is described by hand. Many _ bins are alternately filled with stable nozzles for the vertical part to tilt in the feed direction. The stable nozzles can be smoothly found, and the pressure of the carrier can be checked. J The internal pressure adjustment section can be slightly higher than the pressure inside the funnel. The group was filled with powder granules and given powder granules. And the acceleration gas combined with the acceleration of the oblique inclined gas is blocking blocking.

Description of the invention (18) With the speed of the partial velocity of the granular body in the conveying direction from the accelerated gas nozzle, it can be smoothly merged into a unified amount Limited to the smallest range. And because of the blocking area of the blocking tube and the change in speed, what is the best shape? The acceleration gas emitted from the Form 1 can be accelerated above the speed of the air in the air conveying pipe to keep the air blown in the air conveying pipe constant. Therefore, it is possible to suppress the interruption and smooth the interruption. Fig. 7 is an explanatory diagram of the first embodiment of the present invention.

Now, if the side of the discharge port 204a is blocked ', the powder and granules are discharged from the discharge port 204a to the conveying pipe 205a, and are conveyed to the downstream side by the air flow injected from the purge pipe 2 0a. At this time, the on-off valve V2 of the 'injection pipe 20 6b' maintains its open and closed state, and no injection air is injected into the transport pipe 20 5b. During the transfer of the transfer pipe 205a, if the transfer pipe 205 becomes clogged, it is detected by the clogging signal detection device 21 0a, and the clogging signal is turned into the control device 2 11. After the blocking signal is input, the control device 2 11 will open and close the valves v! And V !, close the valve OPEN, close the valve V2 and V /, and change the direction of rotation of the drive motor 203 to the reverse direction. In this way, the spiral feeder 202 starts to reverse, and the powder and granules in the storage bin 201 are discharged from the discharge port 204b, and the supply transfer pipe 205b 'is transported to the downstream side by the air flow injected from the blowing pipe 206b. In this way, after the transfer channel is switched from the transfer pipe 205a to the transfer pipe 205b, the clogging of the transfer pipe 20 5a becomes "standby": When the transfer pipe 205b becomes clogged, the transfer pipe is opened in the same operation. Switch to the transfer pipe 205a. In the above-mentioned embodiment, when the conveyance path is blocked and protected, it is switched to another conveyance path, so it is not recognized.

Description of the invention (20) However, 'the main part of the jam is the dispenser, so in this embodiment, the dispenser is deleted from the transport path' so as to avoid the jam on the transport path. Fig. 8 is an explanatory diagram of the second embodiment, and the same parts as those in Fig. 7 are assigned the same component numbers, and the descriptions of these parts are omitted. In the figure, 213 is a spiral feeder, with the axis as the dividing line to form a left-right symmetrical spiral. When the spiral feeder 2 i 3 is rotated, the powder and granules in the storage bin 201 are fed from the spiral. The discharge ports 204a and 204b provided at both ends of the device 213 are blocked by the same amount, and they are respectively supplied to the conveying pipe. The sprayed air stream supplied from the powder blowing pipes 206a and 206b to the transfer pipes 205a and mb is transported to the next. According to this implementation mode, the age is moved, but the storage material is not being transported. It is not necessary to set the branch i during the middle of the trip if the branch is not broken. Therefore, the transport pipe is blocked in the transport pipe.

The powder and granules supplied to the storage bins 201B and 201C are blocked by the two discharges a204B, 204Bb, 204Ca, and 204Cb in equal amounts, respectively. As a result, four transfer pipes 205Ba, 205Bb, and the like can be supplied in equal amounts. In the same way, by combining a plurality of sets of blocking devices composed of a storage silo and a screw feeder, as long as the powder and granules are put into a storage silo, a plurality of conveying pipes can be supplied. The above-mentioned blocking devices are grouped into three groups to form multiple groups, so that more users can perform quantitative blocking. This preferred embodiment 2 has the above-mentioned structure, so it has the following effects. There are some options. There is a device that can continuously carry powder. It is equipped with a discharge pipe feeder piping detection device. It can discharge multiple pipes when the pipe is blocked. Use the air inlet of the upper body and connect the storage and connection to the measurement and transportation with the blocking signal to selectively 'continuously move the powder and straighten Γ. When the pipeline is connected to the transportation and the pipeline is blocked, the screws blocked at both ends are placed in each The control of the blockage detection direction is described. A large number of root passages occur, and a large amount of powder particles are blocked. Each discharge port is transported separately with the transfer port and the above-mentioned many streams. Therefore, it is being transported. The passage has a storage container for storing powder and granules. The powder and granules stored in the storage container quantitatively describe the conveying piping of each discharge port, a clogging detection device provided with a clogged tube, and input and switch the rotation of the screw feeder. Many of the above are also used.

¥ '4 V. Description of the invention (22) The screw feeder with two outlets at the end of the spiral shape can dispense the powder when the powder is blocked. Therefore, it is not necessary to install a distributor during the transportation of the piping, and it is not easy to cause a blockage during the transportation of the piping. In addition, the storage container for storing powder particles and the blocking device of the screw feeder provided with a discharge port at both ends of the spiral shape whose axis is symmetrical about the center line are in a group of three, at least one group of powder particles For the bulk blocking device, two of the above three are arranged side by side. 'The other powder and granules blocked from each discharge port are supplied to the storage container of the above two granule blocking devices. The same amount of powder and granules are blocked for many transfer pipes. Best-shaped bear 3 Embodiment 1 In this embodiment ', as the high-temperature and high-pressure reaction furnace, an example in which pulverized coal is sprayed from a blast furnace made of iron ore and coke iron can be cited.

FIG. 10 is an explanatory diagram of the device of the first embodiment. In the figure, 301 is an injection storage tank for storing powder and granules such as pulverized coal, and 303 is a blocking device capable of quantitatively blocking the powder and granules, which is provided below the mouth blowing storage tank 301. 05 is a transfer pipe for transferring the powder and granules blocked by the injection storage tank 303 to the blast furnace 207. S 3 0 9 is an injection piping that communicates with the carrier pipe 305 to supply carrier gas, 311 is a compressed carrier gas compressor provided at the injection pipe 3 0 9, and 3 丨 3 is provided at the compression side. The cooler for cooling compressed gas, 3, 5 is a bypass tube bypassing the crying cry. Next, the operation of this embodiment with the above-mentioned configuration will be described. When the high pressure is set to 4kg / cm2 (head pressure), considering the typical loss of the transfer pipe 305, the internal pressure of the injection storage tank 301 is about 7.5kg / cm2 (head pressure) = and

V. Description of the invention (23) and 'for stable delivery of powder and granules at a ruler of 5 kg / cm2 (head pressure)' If the minimum gas flow rate at atmospheric pressure is set to 20 m / s, the gas flow rate It takes about 7.0 m / s. In this embodiment under the above conditions, the pressure of the carrier gas is increased to 8 kg / cm2 (head pressure) by the compressor 3 丨 1, and the carrier gas is supplied through the bypass pipe 31 3 without passing through the cooler 31 3 Transfer pipe 3 05. When the pressure of the carrier gas is increased to 8 kg / cm2 (head pressure), the temperature of the carrier gas is increased to 3110 ° C during the compression process. Then, the inner diameter of the piping was set to 38.4 mm in Shanghai, and the inlet gas temperature of the transfer piping 305 was set to 100. (: (10 ° c lower than the inlet temperature of the shrinking machine), in order to obtain the required gas flow rate of 7m / s' the required gas flow rate should be i87Nm3 / h. For this, without bypass pipe 31 5 When the cooler 31 3 sets the carrier gas temperature to 20 ° C, in order to obtain the required gas flow rate of 7 m / s, the required gas flow rate should be 238 Nm3 / h. Therefore, according to this embodiment, compared with the previous carrier gas amount, Only about 79% of the gas can be used. Therefore, while reducing the capacity of the compressor, the amount of gas injected to the blast furnace is reduced, so that the temperature of the furnace can be prevented from being lowered. Transport in the high temperature state of blowing waste plastic When the powder and granules are in a semi-melted state and are liable to stick to the side wall of the pipe and cause clogging, part of the compressed gas added by the compressor 311 flows into the cooler 31 3, and the other part flows into the bypass pipe 315 to adjust the transfer pipe The inlet temperature of 305 is sufficient. Fjfe Form 2. In this embodiment, it is possible to achieve by setting the minimum allowable speed of the carrier gas.

g9113499.ptd Page 26 V. Description of the invention (24) Reduce the amount of wear of the carrier gas piping to prevent the reduction of the thermal efficiency of the combustion furnace. Before explaining the specific device, the principle will be explained first. It is considered that the minimum gas flow rate for stably transporting the powder and granules is proportional to the final velocity of the particles. The final velocity of the particles varies with the pressure of the protective atmosphere 'under atmospheric pressure depending on the properties of the particles (particle diameter, particle density, etc.) and the solid-gas ratio. That is, the final velocity (Ut) of the spherical particles is obtained by the formula (!). Ut = g (PP- / 0 f) x dp2 / 18 β (Ar < 104) dpx (4g2 (pp- pf)) 2/225 pi β) ιη (104 < Ar < 9. 43 x 1 04 ) (1) (3g (PD- P f) dp / pf) 1/2 (9. 43 xl04 < ^ r < 3 xi〇9) where Ar = dp3 j〇f (p p- pf ) / Hong 2 pp: Particle density (kg / m3) pf: Gas density (kg / m3) dp _ · diameter (m) #: Gas viscosity (Pa.s) g: Gravitational acceleration (m / s2) Particle diameter ( When dp) is a powder or granule of about 2 mm or more, Ar > 9.43 x 104. (Eg 'PP: 1 000kg / m3, P f: 1 kg / m3, dp: 2mm, kernel: 189xlO'7Pa. S, g: 9.8 m / s2 * Ar = 2.2 xl05, Ar > 9_43x 1 04 .) Therefore, formula 3 in formula (1) applies. And pf is proportional to p ’, so the relationship between the final velocity of pressure (P1) (UD and the final velocity (UtD) in the atmosphere (p)) can be inferred as follows:

Ut ^ Utp (P0 / P1) 1/2 (2) From the above formula, it can be considered that when the atmospheric pressure changes, the final velocity is proportional to the square root of the pressure (Equation 2). Therefore, in order to stabilize the minimum air velocity (U lin) of the conveying particles, which is related to the pressure in the conveying pipe, the equation (3) can be used.

Hin0 X (P0 / P1) Μ (3) where Umin: minimum flow rate under pressure in the transfer tube, ni / s Uaiin〇: minimum flow rate under atmospheric pressure, m / s P0: atmospheric pressure, kg / cm2 P1: inside the transfer tube Pressure, kg / cm2 As can be seen from the above formula, by calculating the minimum flow rate (U) at atmospheric pressure, the minimum flow rate (Umin) at the pressure in the transfer pipe can be obtained from formula (3). The flow rate of the carrier gas is set above the minimum gas flow rate (Um i η) obtained above, and powder and granules can be transported stably. It is best to set the flow rate close to the minimum gas flow rate (Umin) to reduce the friction on the piping. Next, the method and device for controlling the flow rate of the carrier gas will be described in detail using the above-mentioned principles. Blocking _. Breaking device for blocking the conveying pipe.

And FIG. 11 are explanatory diagrams of the apparatus of this embodiment. 301 is an injection storage tank for storing powder and granules such as pulverized coal, and 303 is a mechanical block device for quantitatively removing powder and granules from the injection storage tank 301. It is a pressure detection for conveying powder f force. It is a plate pressure. Detector screw feeder and other mechanical blocking devices. With this type, it is possible to reduce or even eliminate the carrier pipe for the carrier gas when blocking the powder. 321 is the internal pipe for detecting the carrier pipe 305, 323 is a flow regulating valve for adjusting the carrier gas, 325

458935 V. Description of the invention (26) 3 The detection signal of 21 calculates the minimum flow rate and the flow rate of the carrier gas and controls the control device of the flow regulating valve 323 according to the calculation result. The operation of the device having the above-mentioned structure will now be described. First, the minimum flow velocity of the powder particles under atmospheric pressure is determined in advance according to the specifications of the powder particles to be transported, and stored in the control device 3 2 5. Then, when the actual powder and granules are blown, the pressure in the conveying pipe 3 0 5 is detected by the pressure detector 321, and based on the detected value, the control device 3 2 5 determines the minimum value under the actual pressure by means of formula (3). Flow rate, control flow rate adjustment 3 2 3 'Adjust the powder flow rate to this minimum flow rate. In this way, the blowing can be performed at the lowest flow rate under the pressure of the transfer pipe, thereby reducing the wear on the transfer pipe. Next 'gives examples of the actual tests performed. The specifications of the transfer system for this experimental example are as follows: Pressure in the reactor: 4kg / cm2 (head pressure) Transfer pipe diameter: 40A (inner diameter 38.4mm) Transfer pipe length: 150m Powder density: 1 000kg / m3 powder Particle flow rate: 1 80Okg / h The powder and granular materials were transported in an atmospheric atmosphere. As a result, the minimum gas flow rate (UEin0) for stable transportation of powder and granular materials was umin0 = 14m / s. In the planned transportation system, we must consider a certain wealth, and set the minimum gas flow rate at 11-0 = 20 claws / 5. The pressure of the transfer pipe at the lower part of the spray tank outlet p = 7.5kg / cm2 (head pressure). The outlet of the injection tank is the inlet of the transfer pipe (p = 7.5kg / cm2 (meter-

89113499.ptd Page 29 ^ 4 58 9 3 5 V. Explanation of the invention (27) Pressure) The gas flow rate obtained using the above formula (3) is 7_ Om / s. Similarly, using formula (3) can The lowest flow velocity in the pressure range from atmospheric pressure to 7.5 kg / cm2 (head force) is shown in the solid line of the graph in FIG. 12. However, the lower the internal pressure of the transfer pipe, the lower the downstream pressure. The gas flow velocity increases when the internal pressure of the pipe decreases, so the flow velocity becomes faster toward the downstream. The gas flow rate at the inlet of the transfer pipe (P = 7.5kg / cm2 (head pressure)) is set to 7. Om / s. The tendency of the gas flow rate to increase due to the decrease in the pressure in the transfer pipe is shown by the dotted line in Fig. 12. Comparing the solid line in Figure 12 with the dashed line, it can be seen that the dashed line is always above the solid line. It can be seen that the gas flow rate at the inlet of the transfer pipe (p = 7.5kg / cm2 (head pressure)) is set at 7. The powder and granules can be transported stably at 0 m / s. When the gas flow rate at the inlet of the transfer tube (P = 7_5kg / cm2 (head pressure)) is set to 7.0 m / s, the gas flow rate reaches a maximum of 12 m / s (the flow velocity at the tuyere). No problem with wear. The required gas flow rate Q = 224Nm3 / h, the solid-gas ratio can reach 6 or more, and the low carrier gas 3E and the solid-to-solid gas ratio are realized. As described above, according to the present embodiment, it is possible to realize stable powder conveyance while reducing the abrasion of the conveying pipe and increasing the solid-gas ratio. (Embodiment 3) In Embodiment 2, the method of setting the minimum flow rate is shown, and the minimum flow rate at the inlet of the transfer pipe is shown. However, as shown by the dashed lines in Figure 12, it is set only at the entrance of the transfer tube.

458935 V. Description of the invention (28) When the minimum flow rate flows downstream, the flow rate increases to exceed the required minimum flow rate due to the decrease in the pressure in the tube (solid line in Figure 3). In the third embodiment, the conveyance close to the lowest flow rate is realized in the entire conveying path. FIG. 13 is an explanatory diagram of the third embodiment. In the figure, the same parts as those in Embodiments 1 and 2 are denoted by the same reference numerals, and these are omitted. Reference numeral 331 is a carrier gas discharge device which is provided at a number of locations along the transportation pipe 305 and discharges a carrier gas by a predetermined amount. Fig. 4 is an enlarged explanatory diagram of the carrier gas deflation device. The carrier gas degassing device 3 3 1 includes: a porous pipe member 3 3 added to the transfer pipe 3 05; a chamber 3 3 5 surrounding the porous pipe member 3 3 3; and a detection device installed in the chamber 335 Pressure gauge 337 for the pressure of the carrier gas, the exhaust pipe 3 3 for the gas in the exhaust chamber 335, the exhaust pipe valve 3 3 9 installed in the exhaust pipe 3 4 1, the flow meter 3 3 9 installed in the exhaust pipe 3 4 3. The length of the porous tube member 333 is designed to have an optimal size in consideration of the gas flow rate of the gas release portion. In the carrier gas degassing device 331 with the above structure, when the carrier gas passes, the carrier gas is discharged to the side of the chamber 3 3 5 from the numerous small holes of the porous pipe member 333, and the chamber 335 is opened by opening and closing the valve 341. The internal carrier gas is discharged to the outside. In this way, the carrier gas is uniformly discharged throughout the entire circumference and the entire length of the porous pipe member 333 into the chamber 335 °, so that no powder or particles are retained in this portion. Hereinafter, based on the carrier gas release device 331 configured as described above, the role of the carrier gas from the transfer pipe 305 and the specifications of the carrier gas in the specific example are as follows:

89113499.ptd Page 31 4 SB 9 3 5 V. Description of the invention (29) ^ • Pressure in the reactor: 4kg / cm2 (head pressure) • Transfer tube diameter: 32A (inner diameter 32.9mm) • Transfer tube length: 150m powder flow rate: 30.0kg / min. The piping diameter of the conveyance is 3 2 A. The powder flow rate is 3.0 kg / min, and the minimum flow rate at atmospheric pressure is determined from the experimental or calculated value to 14. 15 m / s, then multiplied by the safety factor of 2.0 · 28 to obtain 28. 30 m / s. At this time, the amount of carrier gas was 4.08 Nm3 / min at a conveying pressure of 8.0 kg / cm2, and the productivity was 0 ° c at this time. When the outlet pressure of the injection tank is set to 8.0 k g / c m2, the minimum flow velocity of the plant gas at that place can be obtained by the formula (3) of Embodiment 2 and is 10. Om / s. Here, the behavior when the flow velocity of the gas at the outlet of the injection storage tank is 10.0 m / s is shown in Table 1. From Table 1, it can be seen that the transport air velocity of 50m from the spray storage tank is Π · 43m / s. However, the pressure at this location was reduced to 7-0 kg / cm2, and the minimum gas flow rate here was calculated using the formula (3) of Embodiment 2 and the result was 10.7 m / s. The carrier gas discharge device 31 is deflated so that the distance from the injection storage tank is 50m and the gas flow rate is i0_7m / s. The outgassing amount is (11.43-10 7) X (32. 9/2) 2 π X 7 = 0.259Nm3 / min. Table 2 shows the behavior when the amount of gas released from the blower tank 50 m is 0.259 NmVmin. The pressure values calculated above are absolute values. 288Nm3 / min 的 气 线 When the volume of air released from the injection tank 100m is 0.288Nm3 / min.

458935 V. Description of the invention (30) is shown in Table 3. Fig. 15 is a graph of the behavior shown in Table 3, the vertical pumping is the gas flow rate, and the horizontal axis is the distance from the spray storage tank. It can be seen from the curve that many gas release points are set in the middle of the carrier gas piping. By determining the gas flow rate required at each point, compared with the absence of gas release points on the way, the flow rate is reduced and a high solid-gas ratio is achieved. And reduce the wear of the transfer pipe. In the above embodiment, two gas outgassing points are given. In fact, the more the gas outgassing points, the smaller the fluctuation of the gas flow rate in the pipe, so it is better to take more gas outgassing points. As an example of the porous tube member, sintered metal is used. The present invention is not limited to this, as long as it is a member made of other materials, it can be a porous member and the gas can be released through the entire tube member. Since the best mode 3 has the structure described above, it has the following effects. The powder and granular injection method in which powder and granules are sprayed with a carrier gas, because a high-temperature carrier gas is used, the amount of the carrier gas can be reduced. While reducing the capacity of the compressor for compressing the carrier gas, the blast furnace is injected into the blast furnace. The amount of gas in the furnace can be reduced, so that the temperature in the furnace can be prevented from decreasing. The table shows the formula for determining the minimum gas flow rate at the pressure in the transfer pipe from the lowest flow rate at atmospheric pressure. According to this formula, the carrier gas amount is set so that the carrier gas velocity in the transfer pipe is the minimum gas flow rate, so the minimum flow rate under pressure can be achieved The injection achieves a high solid-to-gas ratio and reduces the wear of the transfer pipe. Here, the minimum gas velocity is the lowest gas obtained through experiments and calculations.

In addition, there are many gas release points on the way of wearing the gas piping. 'Because the powder and granular materials need to be transported at a low gas velocity, the carrier gas piping path can be transported near the lowest flow rate. In total, high solid-gas ratio and friction loss of carrier gas piping can be prevented.

The second knife S 410 ′ 411 is an air conditioning nozzle provided near the splitter 403 of the second branch pipe 404 and 405, respectively. The nozzle 4 丨 〇, * blows air that increases resistance to the material flow in the distribution path. As an example of increasing the resistance 1, the axis of the air blowing direction and the axis of the eight branch pipes 404 and 405 on the downstream side of the blowing part are controlled within a 90 ° angle.

In the latter 038mm, the cross-sectional area of the 7 pipes conveyed before and after the branch is basically equivalent. The operation of the embodiment having the above-mentioned structure will now be described. From the above, the difference in resistance of the conveying pipe is formed by the difference in length between the i-th and second branch pipes 404 and 4.05, or it is distributed to the first and second branches according to the manufacturing error of the distributor 403. There is a difference in the amount of waste plastic in the tubes 404, 405. The air for adjustment is sprayed from the blasting 410, 411 in the direction of increasing the air resistance, and the flow rate of the powder and granules flowing when the air is sprayed to one of the branch pipes is smaller than that when the air is not blown, and The amount of powder and granules in the other branch pipe of the empty milk is adjusted by not blowing or less blowing, so that the two spray guns have the same final flow. In actual control, a powder flow measurement device is installed in each of the branch pipes 404 and 405, and based on the detection result of the powder flow measurement device, the injection of the nozzles 41, 411 is adjusted to adjust the air volume.

As can be seen from Figure 19, when the difference in the amount of regulated air is 0 (for example, when I and W2 are both 0), the difference between the waste plastic flow of the first and second branch pipes 4, 5 is about 55kg / h If the flow rate of the air for regulation of the first branch pipe 4 is increased, the difference between the amount of air for the spray regulation of the first and second branch pipes 4, 5 can be controlled to about 15Nm3 / h. The total flow is about 4 40 kg / h, which makes the flow of the two consistent. As shown in Fig. 19, the flow rate of each branch pipe can be controlled within a wide range by adjusting the air blowing. In this way, according to this embodiment, only relatively simple means can be used to prevent the conveying pipe from being clogged, and the distribution control of the powder and granules can be performed in a wide range. In the above-mentioned embodiment, the example in which the nozzles 4 1 0 and 41 1 are provided on both the first and second branch pipes 4 and 5 is given. When the transfer pipe is divided into two branch pipes by the distributor 3, for example, the pipe resistance is relatively small. When it is small and not adjusted, it is also possible to install a nozzle for adjusting air in the branch pipe of the two parts with a large amount of conveyance. Moreover, in the above-mentioned embodiment, it has been shown that the carrier gas is caused by the nozzles 410 and 411.

However, in the present invention, 'therefore it seems to spray air toward the resistance of a branch pipe with a small flow rate. 'It is also possible to spray the carrier stream in a direction orthogonal to it. In the above-mentioned embodiment, although there are no special regulations regarding the positions where the nozzles 41 0 and 41 1 are provided, it is preferable to set them immediately after the distributor 3. Embodiment 2 FIG. 20 is an explanatory diagram of Embodiment 2 of the present invention. In this figure, the same or corresponding parts as those in Fig. 16 describing Embodiment 1 are given the same component numbers. In this embodiment, in order to prevent the powder and granules remaining in the branch pipe from being clogged when stopped during transportation, air is blown into the branch pipe to make the powder and granule flow. Specifically, 'the three branch pipes 404 of the distributor 403, 405 and 413 are provided with on-off valves 4 0 6, 4 0 7 and 4 15. At the same time, on the upstream side of the on-off valves 4 06, 4 07 and 415, nozzles 41 0, 411 and 416 for cleaning air are provided. The inclination angles of the nozzles 410, 411, and 416 are not particularly specified, but it is required to set and set the pressure of the air sprayed by each nozzle to be higher than the pressure of the carrier gas. a Next 'is the operation of this embodiment. For example, when the branch pipe 4 丨 3 needs to stop the waste plastic transportation, close the on-off valve 4 to block the transportation path. Then, air is blown from the nozzle 416. By blowing air, the waste plastic existing between the distributor 403 and the opening of the branch pipe 413 is allowed to flow, thereby preventing waste plastic plugs in this area. ~ 3 days a day Stop when plastic waste is sprayed with branch pipe 413 *

In summary, according to the present embodiment, the clogging of the powder particles in the conveying pipe can be prevented with a simple structure, and the branch pipe and the opening and closing state can be flexibly selected according to the situation of the user. In the first and second embodiments described above, the distribution control of powder and granules and the prevention of clogging of the conveying pipe are respectively described. In the second embodiment, there is no special regulation on the nozzle spray direction. The resistance air flow nozzle can be used for the distribution control of waste plastics during the transportation process, preventing the waste plastics from being blocked due to the transportation stop. The best mode 4 has the structure described above, and therefore has the following effects. In the conveying path on the downstream side of the distributor, the air flow that acts as a resistance against the stream is sprayed 'to adjust the balance of the flow rate of the powder and granules flowing in each conveying path'. Therefore, the blocking of the conveying pipe can be prevented by simple means. It can control the distribution of powder and granules in a wide range. When the conveying path on the downstream side of the dispenser is interrupted, gas is blown on the blocked path to 'fluidize the granules in the interrupted path and prevent clogging of the conveying path'.卩 W IX 士 丨 Fangzhi powder blockage in the transport tube. According to the user's tool / ′, the branch pipe can be flexibly selected and the transfer start and stop can be controlled. On the way to carry money '3 shirts ...

The on-off valve of the on-off valve, and the injection of gas on the above-mentioned on-off valve and distribution channel are used to blow the gas on the upstream side to distribute the gas evenly, and at the same time prevent the optimal opening and closing of the bear. The nozzles are arranged between the nozzles, and the nozzles are directed from the downstream side, so that the particles can be clogged when the particles are stopped during transportation. The present embodiment relates to detection of clogging of a transport path. Fig. 21 is an explanatory diagram of the first embodiment of the present invention. The present invention is an example of a gas feed line for blowing waste plastic as a fuel from a tuyere into a furnace in Gaocheng. In the figure, 501 in the figure, while storing the fuel waste plastic,

It is also a spray storage tank that is blocked by a constant amount. 502 is connected to the spray storage tank 501 while constituting a transport path. 503 is a ground wire provided at many parts of the transport tube 502. 504 is On the way to the transport tube 5 0 2, a clogging detection device '5 0 5 detects the clogging of the conveying incinerator, which is a blast furnace 5 06.

That is, the charging-discharging-charging-discharging curve is continuously managed at all times to determine whether the powder and granules are normally transported. The operation of this embodiment having the above-mentioned configuration will now be described. The waste plastic blocked from the injection storage tank 501 is pressured by the injection air into the conveying pipe 5G2, and injected into the blast furnace 506 by the injection 505. Since static electricity is generated by friction between different substances, static electricity is also generated between the waste plastic in the transfer pipe and the transfer pipe 502. The static electricity generated by the transfer pipe 502 is discharged from the ground wire 503 'without causing the entire transfer pipe 502 to be charged with static electricity. The static electricity generated by the charged pipe 5 13 is not transmitted to the side of the transfer pipe 502 through the insulating materials 511a and 511b, and is repeatedly discharged through the ground wire 51 7 by the charged controller 5 15 at a certain time interval. Fig. 23 shows the charging-discharging curve in the charging controller 515. The ordinate is the charging voltage and the time is plotted on the abscissa. When carrying it correctly, for example, it is charged and discharged once every certain period of time in the area A of Figure 23. The charging-discharging-charging-discharging time interval can be adjusted from the unit of "second" to the unit of "minute". When the transfer tube 502 is blocked in the middle, the waste plastic will not flow in the transfer tube, so if As shown in area B of Figure 2 3, the live piping 513 will no longer be live. In this way, the live controller 5 will issue an alarm when it is not live for more than a certain period of time. The types of alarms are: for example, the alarm light is on-off Astigmatism, alarm signal in the central monitoring room, etc. 'At the time of unblocking', as shown in area C of Figure 23, it will be charged and discharged again at regular intervals.

This is because as long as the flow of the conveying tube 50 body, as long as the powder and particles, no clogging. ': In particular, more or less powder will cause static electricity. Any location or 4 = rf5 ° 2 'on 4 is only given one detection device; hi more than 2 detections are set on the injection pipe 502. The static electricity may occur depending on the type of powder and granules to be transported. Therefore, the length of the charged pipe 513 should be selected according to its characteristics. The material of the pipe 513 is listed, and steel is used to generate static electricity by friction with the material being transported. Pressure materials can be used, such as resin series materials are also possible. (Embodiment 2) This embodiment relates to the release of the clogging d in the conveying pipe.

Description of the invention (40) In the embodiment with the above structure, during normal operation, the raw materials ejected from the spray storage tank 501 are blocked. The waste plastic powder and granules are blown into the conveying pipe 502 through the mouth, and then sprayed into the blast furnace 506 through a spray gun 505. At this time, the interruption intervals, V3, and V4 are in an open state ', and the interruption valves V !, V5, and V6 are in a closed state. On the other hand, when the injection raw material is blocked in the transfer pipe 502, the injection of the injection air is stopped, and the shutoff valves V !, V5, Ve are opened, and the shutoff valves &, V3, and V4 are closed. In this state, the high cleaning air is blown from the cleaning air pipe 5 2 5. In this way, the blockage of the transfer pipe 5 02 can be removed, the blockage can be removed, and the blockage blocked at the upstream side of the shutoff valve V4 of the transfer pipe 5 02 can be collected by the collection box 5 by back blowing the transfer pipe 2. 2 2 Collect the clogged material on the downstream side of the shut-off valve, flow to the downstream side of the transfer pipe 502, and blow it into the blast furnace from the spray gun 505. The clogged object blocked on the upstream side of the shutoff valve V4 receives a gas pressure 'in the opposite direction to the clogging, so that the force for releasing the clogging can be made smaller. On the other hand, 'on the downstream side of the shut-off valve', since the shut-off valve v4 is provided on the downstream side, the volume of the transfer pipe 502 from the shut-off valve V4 to the spray gun 505 is small, and it has a relatively large effect. Force can release the blockage. It is considered that when high-pressure air is blown from the cleaning air pipe 5 2 5, the phase 522 is collected to generate dust. The dust can be removed by the dust collector 524 through the pipe 523. ^ ν In summary, according to the embodiment of the present invention, the blockage can be collected by the collection box 5 2 2. Since it is installed outside the system, it is no longer the cause of the blockage. The high pressure air is used to clean the blockage in the opposite direction, so it can be unblocked with less energy.

Moreover, the powder and granules 610 accumulated in the fluidized feed chamber 614 can be arbitrarily fluidized. In this way, even the filled powders and granules can be fluidized as well. At this time, compared with the previous technology, it has a higher solid-to-gas ratio. Regarding the blocking of the powder and granules 61 °, quantitative blocking is not required, and accuracy is not required.
