A partitioned urea hydrolyzer

Abstract

The present invention discloses a partitioned urea hydrolyzer, comprising a partitioning mechanism, a hydrolysis reactor, an isolation portion disposed within the hydrolysis reactor, a blocking portion disposed on the isolation portion, a bracket portion disposed on the isolation portion, a connecting portion disposed on the bracket portion, an output portion disposed on the hydrolysis reactor, and a first extrusion portion disposed on the output portion. The partitioned urea hydrolyzer divides the urea hydrolyzer reaction into partitions. When the ammonia demand of the unit decreases, to ensure that the urea hydrolysis reaction temperature is close to the design value (155°C), a certain partition can be selected to start the hydrolysis reaction to increase the temperature of the hydrolysis product gas and reduce the risk of crystallization. The hydrolysis partition that is not reacting is in a hot standby state, and no urea solution is continuously introduced. Only a small amount of steam is introduced to maintain the solution temperature. This invention can ensure that the ammonia production of the urea hydrolysis reaction is more closely matched with the ammonia demand of the unit, thereby improving the operational flexibility of the urea hydrolysis.

Description

Technical Field

[0001] The present invention relates to the technical field of urea hydrolysis, in particular to a partitioned urea hydrolyzer. Background Art

[0002] The urea hydrolysis reaction usually involves injecting a urea solution with a mass concentration of about 50% into a hydrolysis reactor. After heating to a certain temperature (generally 130-160°C) and pressure (about 0.6MPa), a hydrolysis reaction occurs to produce ammonia, carbon dioxide and water vapor. The product gas generated by the hydrolysis enters the ammonia-air mixer and is mixed with hot dilution air before being sent to the ammonia injection grid.

[0003] For denitrification systems with multiple units, urea hydrolysis reactors are generally used in a common system. The ammonia output of the operating hydrolyzer must at least meet 100% of the total ammonia demand of the units in the plant, and a spare hydrolyzer is set up. When the units are running at low load or some units are shut down for maintenance, the total ammonia demand is small, the hydrolyzer output is also small, the operating temperature is relatively low, and the risk of crystallization during product gas transportation is also higher. Summary of the Invention

[0032] Example 1

[0033] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a partitioned urea hydrolyzer, which includes:

[0034] The partitioning mechanism 100 includes a hydrolysis reactor 101, an isolation portion 102 disposed within the hydrolysis reactor 101, a blocking portion 103 disposed on the isolation portion 102, a bracket portion 104 disposed on the isolation portion 102, a connecting portion 105 disposed on the bracket portion 104, an output portion 106 disposed on the hydrolysis reactor 101, a first extrusion portion 107 disposed on the output portion 106, and a second extrusion portion 108 disposed on the output portion 106;

[0035] The handle mechanism 200 includes a connecting portion 201 provided on the output portion 106 , a handle portion 202 provided on the hydrolysis reactor 101 , and a steam portion 203 provided on the hydrolysis reactor 101 .

[0036] During operation, one, two, or three zones are selected for reaction based on the ammonia demand of the unit. When only one zone is required for reaction, the steam regulating valves of zones 1 and 3 are adjusted to keep them in hot standby mode, while zone 2 reacts. The product gas of zone 2 is transported through the output portion 106. When two zones are required for reaction, the handle 202 is rotated to drive the output portion 106 to rotate the second extruding portion 108. The second extruding portion 108 rotates and squeezes one of the connecting portions 105. The connecting portion 105 moves and squeezes the blocking portion 103, thereby connecting zone 1 with zone 2. The product gas of the two zones is transported through the output portion 106. When three zones are required for reaction, the handle 202 is further rotated to drive the output portion 106 to rotate. The output portion 106 drives the second extruding portion 108 to continue rotating. The second extruding portion 108 continues to squeeze one of the connecting portions 105. Simultaneously, the output portion 106 drives the first extruding portion 107 to squeeze the other connecting portion 105, thereby connecting zone 2 with zone 3. The product gas of the three zones is transported through the output portion 106.

[0037] Example 2

[0038] Reference Figures 1 to 4 and Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the isolation part 102 includes a partition 102a arranged in the hydrolysis reactor 101, and the partition 102a is provided with two through holes 102b arranged on the partition 102a.

[0039] Preferably, the partition 102a is made of 2205 stainless steel, which has high strength, good impact toughness, and good overall and local stress resistance and corrosion resistance. It is circular in shape. The partition 102a divides the hydrolysis reactor 101 cavity into three parts, each of which is provided with a separate steam coil and urea solution inlet. The steam coil interface is arranged in the radial direction of the hydrolyzer, and the ammonia output of a single hydrolysis partition is approximately 1 / 3 of the total output.

[0040] Furthermore, when the unit requires less ammonia, it only needs to start one or two hydrolysis zones to meet the denitrification requirements. Since the ammonia output of the operating hydrolysis zone is relatively large and the reaction temperature is closer to the design value, the risk of product gas crystallization is reduced;

[0041] Furthermore, the reaction temperature of the urea hydrolyzer is generally between 130 and 160°C. The higher the temperature, the greater the ammonia production. When the unit requires a small amount of ammonia, the supply of urea solution and steam to the hydrolyzer can be reduced, but the reaction temperature is also relatively low, and the risk of crystallization during product gas transportation will increase. The present invention is designed into three compartments. When the required ammonia amount is small, one of the compartments is put into use, and the production amount of the compartment is close to the required amount, and the reaction temperature is also relatively high.

[0042] The blocking portion 103 includes a blocking spring rod 103a provided on the partition 102a, a blocking spring 103b provided on the blocking spring rod 103a, a blocking plate 103c provided on the blocking spring rod 103a and adapted to the through hole 102b, and a blocking pad 103d provided on the blocking plate 103c.

[0043] Preferably, the blocking spring rod 103a is slidably arranged on the partition 102a, the blocking spring 103b provides pressure for the blocking plate 103c to block the through hole 102b, and the blocking gasket 103d is made of polytetrafluoroethylene, which has excellent chemical corrosion resistance and a wide temperature resistance range.

[0044] The bracket portion 104 includes a support rod 104a provided on the partition plate 102a, and a support ring 104b provided on the support rod 104a and adapted to the through hole 102b.

[0045] Preferably, the support rod 104a is "L"-shaped and is staggered with the blocking spring rod 103a to ensure normal use of the device. The support ring 104b is used to install the connecting pipe 105a, and the connecting pipe 105a is slidably set in the support ring 104b.

[0046] The connecting portion 105 includes a connecting tube 105a disposed in the support ring 104b, a first connecting hole 105b disposed on the connecting tube 105a, a second connecting hole 105c disposed on the connecting tube 105a, an extrusion head 105d disposed on the connecting tube 105a, a tail sealing plate 105e disposed on the connecting tube 105a, and a protrusion 105f disposed on the tail sealing plate 105e.

[0047] Preferably, the connecting pipe 105a is a tube body to ensure that the product gas can pass through the connecting pipe 105a. The first connecting hole 105b allows the product gas from partition 1 or partition 3 to enter the connecting pipe 105a. The second connecting hole 105c allows the product gas in the connecting pipe 105a to enter partition 2, ensuring the connectivity of the device. The extrusion head 105d facilitates the connecting pipe 105a to enter the through hole 102b. The setting of the tail sealing plate 105e is not only used to install the protrusion 105f, but also to ensure that the product gas can flow out through the second connecting hole 105c. The protrusion 105f is hemispherical, which reduces friction and increases the service life of the device. At the same time, it makes the connecting pipe 105a move more smoothly, and cooperates with the setting of the first limiting arc groove 107b, the second limiting arc groove 108c and the fan-shaped groove 108d to limit the connecting pipe 105a and increase the stability of the connecting pipe 105a.

[0048] The output portion 106 includes an output pipe 106a provided on the hydrolysis reactor 101, an output hole 106b provided on the output pipe 106a, and an output rotating disk 106c provided on the output pipe 106a.

[0049] Preferably, the output pipe 106a is rotatably arranged on the hydrolysis reactor 101, and the output hole 106b is located below the output pipe 106a, ensuring that the output hole 106b is located in the hydrolysis reactor 101, thereby ensuring that the product gas can enter the output pipe 106a through the output hole 106b, and the output rotating disk 106c is fixedly arranged at the end of the output pipe 106a.

[0050] The first extrusion portion 107 includes a first extrusion arc plate 107a provided on the output rotating disk 106c, a first limiting arc groove 107b provided on the first extrusion arc plate 107a and adapted to the protrusion 105f, and a first baffle 107c provided on the first extrusion arc plate 107a.

[0051] Preferably, the arc surface of the first extruded arc plate 107a can ensure that the first connecting hole 105b extends through the partition 102a, while ensuring that the second connecting hole 105c is located in partition 2, thereby ensuring the normal use of the device, and the first extruded arc plate 107a rotates 90 degrees to displace the connecting tube 105a to the maximum stroke.

[0052] The second extrusion portion 108 includes a second extrusion arc plate 108a arranged on the output rotating disk 106c, an extrusion fan-shaped plate 108b arranged on the output rotating disk 106c and connected to the second extrusion arc plate 108a, a second limiting arc groove 108c arranged on the second extrusion arc plate 108a, a fan-shaped groove 108d arranged on the extrusion fan-shaped plate 108b, and an arc surface 108e arranged between the second limiting arc groove 108c and the fan-shaped groove 108d.

[0053] Preferably, the shape of the second extruded arc plate 108a is the same as that of the first extruded arc plate 107a, and the angle between the second extruded arc plate 108a and the first extruded arc plate 107a is 90 degrees, ensuring that when the output rotating disk 106c rotates 90 degrees, the connecting tube 105a on the left can be displaced to the maximum stroke, and the displacement stroke of the connecting tube 105a on the right is 0. The extrusion fan plate 108b has the same radius as the second extruded arc plate 108a, and the extrusion fan plate 108b is a quarter ring, ensuring that when the output rotating disk 106c rotates 90-180 degrees, the connecting tube 105a on the left can still maintain the maximum displacement stroke, and the connecting tube 105a on the right can contact the first extruded arc plate 107a. Therefore, when it rotates 180 degrees, the connecting tubes 105a on both sides can be displaced to the maximum stroke at the same time, ensuring the normal use of the device.

[0054] The remaining structures are the same as those of Example 1.

[0055] During use, when two partitions need to react, the handle portion 202 is rotated to drive the output pipe 106a to rotate the output rotating disk 106c, and the output rotating disk 106c drives the second extrusion arc plate 108a to rotate the second limiting arc groove 108c, and the second limiting arc groove 108c squeezes the protrusion 105f to make the connecting pipe 105a move along the support ring 104b, and the connecting pipe 105a drives the extrusion head 105d to squeeze the blocking plate 103c to move the blocking spring rod 103a, and the blocking spring rod 103a moves to squeeze the blocking spring 103b to shrink the blocking spring 103b. At the same time, the connecting pipe 105a drives the first communicating hole 105b to enter the partition 1 through the through hole 102b, thereby connecting the partition 1 with the partition 2. The product gas in the partition 1 enters the partition 2 through the first communicating hole 105b, the connecting pipe 105a, and the second communicating hole 105c, and the product gas in the partition 2 is transported through the output hole 106b and the output pipe 106a.

[0056] When three partitions are required for reaction, the handle portion 202 is continued to be rotated to drive the output tube 106a to rotate the extrusion sector plate 108b, and the protrusion 105f on the left side enters the sector groove 108d along the second limiting arc groove 108c and the arc surface 108e. Since the extrusion sector plate 108b is fan-shaped, the continued rotation of the extrusion sector plate 108b will not continue to squeeze the connecting tube 105a on the left side to move, so that the connecting tube 105a on the left side remains stationary. At the same time, the output rotating disk 106c drives the first extrusion The arc plate 107a continues to rotate, and the first extrusion arc plate 107a rotates to make the protrusion 105f on the right enter the first limiting arc groove 107b. The first extrusion arc plate 107a rotates and squeezes the protrusion 105f on the right to make the connecting tube 105a move along the support ring 104b. The connecting tube 105a drives the first connecting hole 105b to enter the partition 3 through the through hole 102b, thereby connecting partition 2 with partition 3, and then the product gases of the three partitions can be transported simultaneously through the output pipe 106a.

[0057] Example 3

[0058] Reference Figure 1 、 2 , 6, and 7 are the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the connecting portion 201 includes a rotary joint 201a provided on the output pipe 106a, and a connecting mother pipe 201b provided on the rotary joint 201a.

[0059] Preferably, the provision of the rotary joint 201a ensures that the output pipe 106a can be ventilated and rotated, and also ensures the installation of the connecting mother pipe 201b.

[0060] The handle portion 202 includes a handle 202a provided on the output tube 106a, a threaded base 202b provided on the hydrolysis reactor 101, a threaded rod 202c provided on the threaded base 202b, and a stop 202d provided on the threaded rod 202c and adapted to the handle 202a.

[0061] Preferably, the threaded base 202b is fixedly arranged on the hydrolysis reactor 101, the threaded rod 202c is threadedly connected to the threaded base 202b, and the stop block 202d is an arc block, which is rotatably connected to the threaded rod 202c and is used to limit the handle 202a.

[0062] Furthermore, an input gear is provided on the output tube 106a, and an electric motor is provided on the hydrolysis reactor 101. An output gear meshing with the input gear is provided at one end of the output end of the motor. Therefore, the rotation of the output tube 106a can also be controlled by the electric motor, thereby increasing the applicability of the device.

[0063] The steam section 203 includes a steam branch pipe 203a provided on the hydrolysis reactor 101, a steam main pipe 203b provided on the steam branch pipe 203a, a drain branch pipe 203c provided on the hydrolysis reactor 101, and a drain main pipe 203d provided on the drain branch pipe 203c.

[0064] Preferably, steam coils are provided in all three partitions, three steam branch pipes 203a are provided, all of which are connected to the steam coils, and each steam branch pipe 203a is provided with a control valve and a flow meter for controlling the amount of heating steam entering each partition, and three drain branch pipes 203c are provided, all of which are connected to the steam coils, so as to facilitate the unified recovery of steam drain.

[0065] The remaining structures are the same as those of Example 2.

[0066] During use, the connecting mother pipe 201b is connected to the product gas pipeline, so that the product gas can be transported through the output pipe 106a, the rotary joint 201a, and the connecting mother pipe 201b. When the output pipe 106a needs to be rotated, the threaded rod 202c is rotated to enter the threaded base 202b. The threaded rod 202c drives the block 202d away from the handle 202a, releasing the limit on the handle 202a. The handle 202a is rotated to rotate the output pipe 106a, thereby adjusting the connection between the partitions.

[0067] The regulating valve on the steam branch pipe 203a is used to adjust the amount of heating steam entering the partition through the steam branch pipe 203a, so that more heating steam is introduced into the partition that needs to react to ensure that the urea hydrolysis reaction temperature is close to the design value (155°C), and less heating steam is introduced into the partition in the hot standby state to maintain the solution temperature of the partition at about 50°C.
