Description

Technical Field

[0001] This utility model relates to the technical field of desulfurization and denitrification slag discharge equipment, specifically an environmentally friendly desulfurization and denitrification slag discharge equipment. Background Technology

[0002] In desulfurization and denitrification processes, a large amount of slurry is generated. If this slurry is not properly treated, it will not only cause serious environmental pollution, but may also affect the normal operation and service life of desulfurization and denitrification equipment. The slurry discharge pipes of existing desulfurization and denitrification slurry discharge equipment are easily blocked by large particles of impurities in the slurry, resulting in poor slurry discharge and requiring frequent shutdowns for cleaning, which affects production efficiency. In addition, the slurry discharge equipment does not pre-treat the slurry enough to effectively crush and refine large particles in the slurry, resulting in poor effects of subsequent solid-liquid separation and treatment processes.

[0003] Large particles in slurry can have several adverse effects on slurry pumps. They increase flow resistance and reduce slurry flow velocity. Due to the presence of large slurry particles, the pump needs to consume more energy to overcome resistance and propel the slurry during operation. This reduces the pump's effective power and increases wasted energy, leading to a decrease in pump efficiency. Large slurry particles can easily accumulate in the pump inlet, impeller channel, and flow channel, causing blockages. Once a blockage occurs, the pump's flow rate will drop sharply, and it may even cause the pump to malfunction. To clear the blockage, the pump needs to be shut down for cleaning, which will affect the continuity of production and reduce production efficiency.

[0004] Therefore, those skilled in the art have provided an environmentally friendly desulfurization and denitrification slag discharge device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly desulfurization and denitrification slag discharge equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly desulfurization and denitrification slag discharge device includes a slag discharge pipe. A motor is fixedly installed at one end of the slag discharge pipe, which is the input end and the other end is the output end. A slurry pump is fixedly connected to the output end of the slag discharge pipe, and the output end of the slurry pump is connected to subsequent processing equipment. An auger is rotatably connected inside the slag discharge pipe near the input end. The output shaft of the motor is fixedly connected to the auger. A turbine is installed inside the slag discharge pipe near the auger. A density meter and a water inlet pipe are sequentially installed on the turbine side near the output end of the slag discharge pipe.

[0008] As a further embodiment of this utility model: a bearing seat is embedded at the upper end of the slag discharge pipe, and a rotating shaft is fixedly connected to the upper end of the turbine, with the upper end of the rotating shaft being fixedly connected to the inner ring of the bearing seat.

[0009] As a further embodiment of this utility model: a second motor is fixedly mounted on the upper end of the bearing housing by bolts, and the output shaft of the second motor is fixedly connected to the inner ring of the bearing housing.

[0010] As a further embodiment of this utility model: an installation base is embedded at the upper end of the slag discharge pipe, and a through hole is opened on the upper end face of the installation base to penetrate into the interior of the slag discharge pipe, and a rubber sealing sleeve is embedded in the through hole.

[0011] As a further embodiment of this utility model: the density meter is fixedly mounted on the upper end of the mounting base by bolts, and the probe of the density meter extends into the interior of the slag discharge pipe through the rubber sealing sleeve.

[0012] As a further embodiment of this utility model: a sealing seat is embedded at the upper end of the slag discharge pipe, and a water inlet pipe is fixedly connected to the upper end of the sealing seat. The input end of the water inlet pipe is connected to an external water source, and the output end of the water inlet pipe extends into the interior of the slag discharge pipe through the sealing seat.

[0013] As a further improvement of this utility model: a throttle valve is fixedly installed on the water inlet pipe, and the throttle valve is electrically connected to an external controller.

[0014] As a further embodiment of this utility model: a feed pipe is fixedly connected above the slag discharge pipe near the input end, and a discharge hopper is fixedly connected to the upper end of the feed pipe. The discharge hopper is fixedly installed at the bottom of the desulfurization and denitrification tower.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The auger and turbine installed in the slag discharge pipe can pre-treat the slag slurry. The auger can initially transport and stir the slag slurry entering the slag discharge pipe, so that the slag slurry flows more evenly to the turbine. The turbine rotates at high speed under the drive of the motor, crushing and refining large particles in the slag slurry, breaking down large particle clumps into small particles, reducing the risk of slag slurry accumulation and blockage in the pipeline, ensuring the smooth progress of the slag discharge process, reducing the downtime for equipment maintenance due to blockage, and improving production efficiency.

[0017] 2. By installing a densitometer to monitor the density of the slurry in the discharge pipe in real time, the viscosity of the slurry is reflected. When the densitometer detects that the slurry density is too high, that is, the viscosity is too high, the external controller will control the throttle valve on the water inlet pipe to open and inject water into the discharge pipe to reduce the viscosity of the slurry. When the density is appropriate, the throttle valve closes and stops injecting water. This ensures that the viscosity of the slurry is always kept within the optimal operating range of the slurry pump, which improves the pumping efficiency, reduces pump wear, and extends the service life of the equipment.

A motor 4 is fixedly installed at one end of the slag discharge pipe 1. The end of the slag discharge pipe 1 with the motor 4 is the input end of the slag discharge pipe 1, and the other end is the output end. A slurry pump is fixedly connected to the output end of the slag discharge pipe 1. The output end of the slurry pump is connected to subsequent processing equipment. An auger 12 is rotatably connected inside the slag discharge pipe 1 near the input end. The output shaft of the motor 4 is fixedly connected to the auger 12. A turbine 13 is arranged inside the slag discharge pipe 1 near the auger 12. A density meter 8 and a water inlet pipe 10 are arranged sequentially on the side of the turbine 13 near the output end of the slag discharge pipe 1.

[0027] Example 2

[0028] Reference Figure 1-5 This embodiment is based on the previous embodiment, but differs in that a bearing seat 5 is embedded in the upper end of the slag discharge pipe 1, a rotating shaft 14 is fixedly connected to the upper end of the turbine 13, the upper end of the rotating shaft 14 is fixedly connected to the inner ring of the bearing seat 5, a second motor 6 is fixedly mounted on the upper end of the bearing seat 5 by bolts, the output shaft of the second motor 6 is fixedly connected to the inner ring of the bearing seat 5, a mounting seat 7 is embedded in the upper end of the slag discharge pipe 1, a through hole 15 extending into the interior of the slag discharge pipe 1 is opened on the upper surface of the mounting seat 7, a rubber sealing sleeve 16 is embedded in the through hole 15, and the density meter 8 is fixedly mounted on the upper end of the mounting seat 7 by bolts. The probe of the density meter 8 extends into the interior of the slag discharge pipe 1 through the rubber sealing sleeve 16. A sealing seat 9 is embedded in the upper end of the slag discharge pipe 1. A water inlet pipe 10 is fixedly connected to the upper end of the sealing seat 9. The input end of the water inlet pipe 10 is connected to an external water source. The output end of the water inlet pipe 10 extends into the interior of the slag discharge pipe 1 through the sealing seat 9. A throttle valve 11 is fixedly installed on the water inlet pipe 10. The throttle valve 11 is electrically connected to an external controller. A feed pipe 2 that penetrates the interior of the slag discharge pipe 1 is fixedly connected to the upper end of the slag discharge pipe 1 near the input end. A discharge bin 3 is fixedly connected to the upper end of the feed pipe 2. The discharge bin 3 is fixedly installed at the bottom of the desulfurization and denitrification tower.

[0029] Working Principle: The slurry generated during the desulfurization and denitrification process flows from the bottom of the desulfurization and denitrification tower into the feed hopper 3, and then enters the slag discharge pipe 1 through the feed pipe 2. Motor 4 starts, driving the auger 12 inside the slag discharge pipe 1 to rotate. The auger 12 transports the slurry entering the slag discharge pipe 1 to the output end, while simultaneously performing preliminary stirring to make the slurry more uniform, preparing it for subsequent processing. Motor 6 drives the turbine 13 to rotate at high speed. When the slurry passes through the turbine 13, the blades of the turbine 13 shear and crush large particles in the slurry, breaking them down into smaller particles, making the slurry finer and improving its flowability. The density meter 8 monitors the density of the slurry in the slag discharge pipe 1 in real time and transmits the data to the external controller. When the controller determines that the slurry density is higher than the set upper limit, it indicates that the slurry is too thick. The controller will control the throttle valve 11 on the water inlet pipe 10 to open, and water from the external water source will flow into the slag discharge pipe 1 through the water inlet pipe 10 to dilute the slurry. After pretreatment and thickening, the slurry is pumped from the output end of the slag discharge pipe 1 and transported to the subsequent processing equipment by the slurry pump for further solid-liquid separation, drying, incineration and other treatments, ultimately achieving environmentally friendly treatment and resource recycling of the slurry.
