Description
Technical Field
The invention relates to a stirring type reactor without dynamic seal, and belongs to the technical field of reactors.
Background
Stirring in a closed reactor generally needs to have a stirring shaft system penetrating through the top or bottom of the tank to transmit kinetic energy, a motor drives a shaft to rotate outside the tank, a stirrer rotates along with the shaft, the structure is complex, the electric energy loss is large, and vibration and noise control is difficult. The reactor is enlarged, the volume and the power of the motor outside the tank are increased, the space occupation is large, and the size and the strength of the stirring system are also increased. There is the bearing seal between the (mixing) shaft that stretches into in jar perpendicularly from jar outside and jar body, and the bearing seal cost is high, and the risk of revealing and polluting is big, and life is shorter, is difficult to maintain moreover. To ensure the sealing of the reactor, a magnetically coupled magnetic stirrer may be used, but the magnetically coupled torque is small, the rotation is easy to lose, and it is difficult to achieve multi-layer stirring.
Because the multiple layers of impellers connected in series in the reactor share the same stirring shaft, the rotating speed and the rotating direction of each layer of impeller are the same, the rotating speed and the rotating direction are difficult to be regulated and controlled respectively, the flow field can be regulated and controlled only by the rotating speed of the stirring shaft and optimizing the form and the specification of each layer of impeller, and the operation flexibility is not strong.
For the emerging gas fermentation, the general stirring reactor is insufficient in utilization of gas because it is difficult to utilize the gas in the head space of the reactor, most of the gas escapes from the reaction liquid after one rising process to leave the reaction system, and the utilization rate of the active ingredient in the gas phase is low.
The self-priming stirring system can suck the gas in the top space of the reactor, and recycle the gas in the top space of the reactor, so that the reaction gas is fully utilized, and the exhaust emission and the exhaust treatment cost are reduced. The self-priming reactor has the advantages of low power consumption, high mass transfer coefficient, good mixing performance, high reaction rate and the like, and can recycle the gas in the reactor without adding equipment outside the reactor. Because an air compression system is not needed, noise pollution of an air compressor is avoided, and factory building area and capital investment are reduced. However, the self-priming reactor also has high-cost dynamic seals, and particularly, if a shaft seal arranged at the bottom of a tank contacts with abrasion solid materials for a long time, the self-priming reactor is easy to damage and difficult to maintain after damage.

Stirring in a closed reactor generally needs to have a stirring shaft system penetrating through the top or bottom of the tank to transmit kinetic energy, a motor drives a shaft to rotate outside the tank, a stirrer rotates along with the shaft, the structure is complex, the electric energy loss is large, and vibration and noise control is difficult. The reactor is enlarged, the volume and the power of the motor outside the tank are increased, the space occupation is large, and the size and the strength of the stirring system are also increased. There is the bearing seal between the (mixing) shaft that stretches into in jar perpendicularly from jar outside and jar body, and the bearing seal cost is high, and the risk of revealing and polluting is big, and life is shorter, is difficult to maintain moreover. To ensure the sealing of the reactor, a magnetically coupled magnetic stirrer may be used, but the magnetically coupled torque is small, the rotation is easy to lose, and it is difficult to achieve multi-layer stirring.
Based on the above problems, the invention provides a stirring reactor without dynamic seal, a vertical upright rod or a hollow upright tube which is not rotated is fixed in the reactor, an integrated motor stirrer is fixed at a proper position of the upright rod or the upright tube, and is immersed in reaction liquid without a rotating stirring shaft passing through a tank top or a tank bottom, so that the stirring reactor has no dynamic seal, and the process adaptability of the reactor is enhanced.
As shown in fig. 1, 2 and 5, the stirring reactor without dynamic seal provided by the invention comprises:
the tank body 100, at least one vertical rod 200 or at least one vertical pipe 203 is arranged in the tank body 100, the upper end of the vertical rod 200 is connected with the tank top 101 of the tank body 100, the lower end is connected with the tank bottom 102 of the tank body 100, the upper end of the vertical pipe 203 is connected with the tank top 101 of the tank body 100 or penetrates through the tank top 101 to be connected with an external vent pipe, and the lower end is connected with the tank bottom 102 of the tank body 100; the number of the integrated motor stirrers 300 is several, and the integrated motor stirrers 300 are assembled on the vertical rod 200 or the vertical pipe 203 for stirring the reaction liquid in the tank body 100.
As shown in fig. 3, the integrated motor stirrer 300 integrates a motor rotor 302 and stirring blades 303, so that the integration of the motor and the blades 303 is realized, the torque generated by the motor is directly transmitted to the rotor 302, the rotor 302 drives the blades 303 to rotate, and a rotary stirring shaft system and a shaft seal system penetrating through the top or bottom of a tank in the traditional stirrer are completely omitted. The stator 301 of the motor is fixed in one piece with the upright 200 or the upright 203. The integrated motor stirrer 300 is much lighter in weight, less noisy, less vibrating, efficient, compact in size, and greater in rotational speed range than conventional stirring systems.
The present invention refers to rotor 302 and blade 303 as an integrated unit as an "impeller" which may be of various designs. The blades 303 on the impeller may be of various types including, but not limited to, flat blade turbine paddles (as shown in fig. 3), pitched blade paddles or propeller blades. Different paddles 303 may achieve agitation of the axial and radial flow. The shape, outer diameter, blade form of the integrated motor stirrer 300 may be designed and replaced as desired.
As shown in fig. 1, the motor of integrated motor agitator 300 is a rim motor 304, comprising a stator 301 and a rotor 302. The stator 301 and the rotor 302 preferably adopt a magnetic levitation technology to reduce friction between the stator 301 and the rotor 302, reduce energy consumption, and improve the service life of the integrated motor stirrer 300. The rim motor 304 may also be directly secured to the can top 101 or can bottom 102.
Rotor 302 of an integrated motor stirrer 300 may be integrated with a single layer of paddles 303 (as shown in fig. 1 and 2), or may be integrated with multiple layers of paddles 303 on rotor 302, referred to as a multiple layer paddle integrated motor stirrer, as shown in fig. 4.
Further, the de-foaming paddle 206 may also be integrated on the rotor 302 of the integrated motor stirrer 300, the de-foaming paddle 206 rotating with the impeller, as shown in fig. 4. The defoaming paddle 206 may be provided with a rim motor 304 independently, as shown in fig. 1 and 5, i.e., the blade 303 of the integrated motor stirrer 300 is replaced by the defoaming paddle 206. The defoaming paddle 206 is started according to the condition of foam and the rotating speed of the defoaming paddle 206 is regulated, when no foam exists, electric energy is saved, when more foam exists, the defoaming paddle 206 is started, and even the foam can be rotated at high speed to be centrifuged on the pipe wall of the tank body 100, so that quick defoaming is realized. The de-foaming paddles 206 that are independently controlled in rotational speed by the rim motor 304 may take a variety of forms including, but not limited to: rake, scraper, turbine, centrifugal, disk.
As shown in fig. 1 and 2, one pole 200 or riser 203 may be serially connected to a multi-layered integrated motor stirrer 300, referred to as a column, and the integrated motor stirrer 300 may be moved up and down along the pole 200 or riser 203. There may be one column in one reactor or a plurality of columns may be arranged in parallel as shown in fig. 6.
To increase the heat exchange area of the reactor, the stand pipe 203 can be used as a heat exchange pipe; the heat exchange tubes (the outer disc semicircular heat exchange tubes of the upright posts 200 are shown in fig. 11A, the outer disc semicircular heat exchange tubes of the upright posts 203 are shown in fig. 11B) can be additionally arranged on the upright posts 200 or the upright posts 203 (the upright posts 203 are shown in fig. 12A and 12B), or the heat exchange tubes are longitudinally and parallelly spliced to form the upright posts 203, and heat exchange fluid is introduced into the heat exchange tubes 211, so that the heat exchange area of the reactor is increased.
As shown in fig. 5, riser 203 is hollow, reducing both the consumption of riser 203 material and weight, and may also open out of the tank through tank top 101 and/or tank bottom 102 to act as a vent pipe.
Each integrated motor agitator 300 may be independently controlled, and the rotational speed and rotational direction thereof may be the same or different, and the rotational speed and rotational direction of each integrated motor agitator 300 may be adjusted according to the flow field regulation and control requirements. Since there may be a plurality of rows of integrated motor agitators 300 in the reactor, the aspect ratio of the large reactor may be smaller, the static pressure in the lower part of the reactor may be reduced, and even the shape of the reactor may be spherical, as shown in fig. 7, under the premise of ensuring the reaction volume. With the same volume, the spherical tank body requires the least area of tank wall material, has stronger pressure bearing capacity, and the tank wall of the tank body 100 can be thinner. In addition, for no aseptic requirement and no airtight reaction, the invention can also be modified into a reactor by adding an integrated motor stirrer 300 in a common tank or groove, as shown in fig. 6.
The compressed gas required by the ventilation reaction needs a gas compressor, the power consumption is very high, and the energy consumption of the air compressor accounts for 30-70% of the total power consumption in the fermentation process. The compressed gas is obtained by utilizing wind energy (the wind power is utilized to drive the wind wheel to rotate, and then the gas compressor is driven to obtain the compressed gas, the compressed gas is stored in the gas storage tank, and the gas is released from the gas storage tank according to the required flow and pressure when in use, the compressed gas is compressed without depending on electric energy, so that the energy consumption cost of the reactor for gas supply can be greatly reduced.
Another way to save on aeration energy is for the stirrer to employ a self-priming impeller 305. The impeller interior of integrated motor stirrer 300 is designed as a hollow, self-priming impeller 305, as shown in fig. 8, with its interior cavity communicating with the interior of riser 203 and communicating with the exterior of the tank, as shown in fig. 5 and 9. The rotating speed of the impeller is improved, and gas can be sucked from the outside of the tank: the impeller rotates to form liquid flow around the impeller to continuously repel the surrounding reaction liquid, when the impeller rotates at a high speed to reach a critical rotation speed, the pressure of the liquid around the impeller is lower than the pressure in the center of a cavity of the impeller, the impeller with the cavity generates pressure difference at the opening at the tail end of the impeller, when the partial pressure drop overcomes the pressure head of the reaction liquid level, gas is ejected at a high speed through the vent pipe to reach the opening at the tail end of the rotor 302, the effects of gas supply and stirring are achieved, and the reaction requirement is met.
As shown in fig. 10, when the suction port 210 is opened at the upper end of the in-tank riser 203, the self-priming impeller 305 sucks the gas in the reactor head space into the reaction liquid through the suction port 210, thereby realizing the recycling of the gas, and thereby, the reaction gas is fully utilized, and the exhaust gas emission and the exhaust gas treatment cost are reduced. If vent pipe C107 and vent pipe D108 are provided in the roof 101, both in-tank and out-of-tank gases may be inhaled, as shown in FIG. 4. As shown in fig. 9, by adding the ventilation communication pipe 109 to the tank top 101 and controlling the opening of the valve and the rotation speed of the self-priming impeller 305, the circulation amount of the gas in the tank and the input amount of the fresh gas outside the tank can be adjusted.
A plurality of vent pipes, such as vent pipe C107 and vent pipe D108, may be connected to other openings of the tank top 101, as shown in fig. 4, and different gases are introduced into different vent pipes, and the gas inlet amount is regulated by adjusting the flow rate of the vent pipes, so as to adjust the ratio of various fresh gases introduced into the reactor. The self-priming impeller 305 can have a variety of designs/configurations and is not limiting of the invention.
