Abstract
Description
Technical Field
[0001] This invention relates to the field of liquid sodium silicate production technology, specifically to an energy-saving and environmentally friendly collector and collection method used in the production of liquid sodium silicate. Background Technology
[0002] Liquid sodium silicate is an important inorganic chemical raw material, widely used in detergents, casting, papermaking, building materials, coatings and other industries. Its production methods are mainly divided into dry method (kiln melting method) and wet method (dissolution method). The wet process usually involves putting solid sodium silicate (block or granular) into a reactor (200), passing steam through it for direct or indirect heating, and adding water. Under high temperature and high pressure (usually 0.6-0.8 MPa, about 160-180℃), the solid sodium silicate is rapidly dissolved to obtain high-concentration liquid sodium silicate.
[0003] After the reaction is completed using this method, a large amount of high-temperature and high-pressure gas-liquid mixture remains in the dissolving vessel. Currently, it is usually received directly using open or semi-open water quenching tanks or collection tanks. However, the gas-liquid mixture carries pollutants such as alkali mist, fine silicate dust, and a small amount of sulfides. Direct emission of this mixture not only pollutes the surrounding environment but also corrodes workshop equipment and buildings. Furthermore, the heat energy carried by this gas-liquid mixture accounts for a considerable proportion of the total energy consumption of the process, and direct emission results in a huge waste of energy.
[0004] Therefore, there is an urgent need to provide an energy-saving and environmentally friendly collector and collection method for use in the production of liquid sodium silicate. Summary of the Invention
[0005] In view of this, the present invention provides an energy-saving and environmentally friendly collector and collection method for use in the production of liquid sodium silicate, aiming to solve the technical problems in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: An energy-saving and environmentally friendly collector for use in the production of liquid sodium silicate, the collector being connected to a reactor for receiving a gas-liquid mixture generated by the reactor and performing gas-liquid separation on the gas-liquid mixture; wherein the gas-liquid mixture includes liquid sodium silicate and steam; The collector includes: A cyclone separator unit includes a cylindrical section and a conical section disposed below the cylindrical section. The cylindrical section has a feed inlet on its side wall and a drain outlet at the bottom of the conical section. A cross-shaped vortex breaker is disposed above the drain outlet. A gas collection chamber is located above and connected to the cyclone separation unit, and is used to collect the gas separated by the cyclone separation unit. The gas outlet on the gas collection chamber is connected to the reactor, the seasoning tank and the pure water storage tank in sequence through the first pipe, the second pipe and the third pipe. The seasoning tank is connected to the reactor, the pure water storage tank is connected to the steam generator and the steam generator is connected to the reactor.
[0007] A further improvement of the present invention is that a first pressure valve is provided on the first pipeline, a second pressure valve is provided on the second pipeline, a third pressure valve is provided on the third pipeline, a pressure sensor is provided in the gas collection chamber, the pressure sensor is connected to a controller, and the controller is connected to the first pressure valve, the second pressure valve and the third pressure valve respectively. The pressure sensor measures the pressure in the gas collection chamber and sends the pressure value to the controller; The controller receives the pressure value P and controls the opening and closing of the first pressure valve, the second pressure valve, and the third pressure valve according to the pressure value P.
[0008] A further improvement of the present invention is that, when the controller determines that the pressure value P > the first threshold P1, it opens the first pressure valve and closes the second pressure valve and the third pressure valve; When the second threshold P2 ≤ pressure value P ≤ first threshold P1, the second pressure valve is opened and the first pressure valve and the third pressure valve are closed. When the pressure value P is determined to be less than the second threshold P2, the third pressure valve is opened and the first pressure valve and the second pressure valve are closed.
[0009] A further improvement of the present invention is that a hollow circular tube with a bottom seal is provided at the center of the cylindrical section, a auger is rotatably arranged on its outer periphery, a demister is provided at the top inside, and the gas collection chamber is connected to the top of the hollow circular tube. The lower part of the hollow tube is provided with several through holes, which are used to allow the separated gas to enter the interior of the hollow tube, so that the gas moves upward and enters the collection chamber after being demisted by the demister.
[0010] A further improvement of the present invention is that the reactor includes a reaction vessel body, which is provided with a packing port, a steam inlet and a steam outlet, wherein the steam inlet is connected to a steam generator; The middle stirring output shaft at one end of the reaction vessel is connected to the rotating assembly, and the middle output shaft at the other end is a hollow shaft. A T-shaped steel pipe is inserted inside the hollow shaft. The free end of the horizontal pipe in the T-shaped steel pipe extends into the interior of the reaction vessel. Six valves are installed on the vertical pipe. The T-shaped steel pipe is connected to six branch pipes through the six valves.
[0011] A further improvement of the present invention is that the free end of the horizontal tube is located between the stirring shaft and the inner wall of the reactor, and is below the liquid level in the reactor.
[0012] A further improvement of the present invention is that the six valves are: a steam valve, a discharge valve, a water inlet valve, a seasoning valve, a pressure gauge valve, and a steam recovery valve; Specifically, branch pipe I is connected to the steam valve and the steam outlet, branch pipe II is connected to the feed inlet of the discharge valve, branch pipe III is connected to the water inlet valve and the water storage tank, branch pipe IV is connected to the seasoning valve and the outlet of the seasoning tank, a pressure gauge is installed on branch pipe V and is connected to the pressure gauge valve, and branch pipe VI is connected to the steam recovery valve and the first pipeline.
[0013] The second aspect provides a collection method based on an energy-saving and environmentally friendly collector used in the production of liquid sodium silicate as described in the first aspect, the method comprising: The gas-liquid mixture generated by the gas-liquid mixture supplied by the reactor enters the cyclone separator unit through the feed inlet, so that the gas-liquid mixture is separated into gas and liquid. The liquid flows down through the inner wall of the cylindrical section and the inner wall of the conical section, and flows out through the drain outlet through the vortex breaker for collection. The gas moves upward, enters the gas collection chamber through the demister, and then returns to the reactor through the first pipe to heat the reacted materials, or enters the seasoning tank through the second pipe to keep the seasoning tank warm, or enters the pure water storage tank through the third pipe to increase the temperature of the pure water entering the steam generator.
[0014] A further improvement of the present invention is that the method further includes: Step 1: Add solid sodium silicate and steam into the reactor through the packing port and steam inlet. Open the water inlet valve to add water into the reactor. Turn on the rotating assembly to make the central stirring output shaft stir and open the steam valve, pressure gauge valve, seasoning valve and steam recovery valve. Step 2: The steam in the reactor flows back into the reactor through the steam outlet and steam valve. This design can buffer pressure fluctuations and avoid sudden pressure changes from impacting the reactor. Step 3: After the reaction is complete according to the pressure gauge reading, open the discharge valve to allow the gas-liquid mixture to flow into the feed inlet; Step 4: The slurry inside the seasoning tank flows into the reactor through the seasoning valve, and the gas flowing out of the collector flows back into the reactor through the first pipe and the steam recovery valve.
[0015] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows: The energy-saving and environmentally friendly collector and collection method provided in this invention for use in the production of liquid sodium silicate utilizes a cyclone separation unit at the bottom. An inlet with a tangential upward tilt of 15-30° causes the gas-liquid mixture to move downwards in a high-speed spiral along the inner wall of the cylindrical section. Centrifugal force throws the denser liquid sodium silicate against the wall and downwards, while the less dense vapor gathers towards the center and rises. The conical section further accelerates the cyclone, improving separation efficiency. A vortex-breaking component above the bottom drain effectively prevents vortices from forming during discharge, avoiding gas entrainment in the drain pipe and ensuring stable liquid discharge.
[0016] Furthermore, by setting up a gas collection chamber at the top of the demister separation unit and dividing the gas outlet into three pipelines connected to the reactor, the seasoning tank, and the pure water storage tank respectively, the waste heat is utilized in stages according to pressure levels: high-pressure steam is directly returned to the reactor for auxiliary heating and bottom jet stirring, reducing fresh steam consumption; medium-pressure steam is introduced into the jacket of the seasoning tank to maintain the slurry temperature ≥80℃ through indirect heat exchange, preventing the solidification of high-viscosity slurry and avoiding contamination caused by direct contact between steam and materials; low-pressure steam is introduced into the coil of the pure water storage tank to preheat the boiler feedwater to 80-90℃, reducing the fuel consumption of the steam generator. This staged utilization method uses steam of different pressure levels "according to quality" during the depressurization process, maximizing the recovery of waste heat.
[0017] Furthermore, by connecting the seasoning tank to the reactor, the prepared slurry is returned to the reactor, realizing the recycling of materials such as solid fine powder and filter residue, thus improving the utilization rate of raw materials. By connecting the pure water storage tank to the steam generator, and the steam generator to the reactor, a closed-loop heat source is formed, further reducing the input of external energy. The entire system achieves a dual closed loop of "material recycling and heat source circulation," which can reduce production costs. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example
[0022] This invention provides an energy-saving and environmentally friendly collector 100 for use in the production of liquid sodium silicate. The collector 100 is connected to a reactor 200 and is used to receive a gas-liquid mixture generated by the reactor 200 and to separate the gas-liquid mixture. The gas-liquid mixture includes liquid sodium silicate and steam. like Figure 1 As shown, the collector 100 includes: A cyclone separation unit 1 includes a cylindrical section 1-1 and a conical section 1-2 disposed below the cylindrical section 1-1. The cylindrical section 1-1 has a feed inlet 1-3 on its side wall. The conical section 1-2 has a drain outlet 1-4 at its bottom and a cross-shaped vortex breaker 1-5 above the drain outlet 1-4. A gas collecting chamber 2 is located above and connected to the cyclone separation unit 1, and is used to collect the gas separated by the cyclone separation unit 1. The gas outlet of the gas collecting chamber 2 is connected to the reactor 200, the mixing tank 300, and the pure water storage tank 400 in sequence through the first pipe, the second pipe, and the third pipe. The mixing tank 300 is connected to the reactor 200, and the pure water storage tank 400 is connected to the steam generator 500. The steam generator 500 is also connected to the reactor 200. The mixing tank 300 includes a tank body and a mixing tank jacket. The tank body is used to premix solid sodium silicate fine powder, process water, and steam to prepare a slurry with good fluidity. The purpose is to pre-wet, pre-disperse, and partially pre-dissolve the fine powder material to provide a uniform and easily reacted raw material for the reactor 200. The reactor 200 is connected to the mixing tank jacket to maintain the slurry temperature through indirect heat exchange and prevent the high-viscosity slurry from solidifying.
[0023] Specifically, such as Figure 1 As shown, the cylindrical section 1-1 has a hollow cylindrical tube 2-1 with a sealed bottom at its center, and a auger 2-2 is rotatably arranged around its outer periphery. A demister 2-3 is arranged at the top inside. The gas collection chamber 2 is connected to the top of the hollow cylindrical tube 2-1. The lower part of the hollow circular tube 2-1 is provided with several through holes 2-4, which are used to allow the separated gas to enter the interior of the hollow circular tube 2-1, so that the gas moves upward and enters the gas collection chamber 2 after being demisted by the demister 2-3.
[0024] The energy-saving and environmentally friendly collector 100 provided in this embodiment of the invention, used in the production of liquid sodium silicate, uses a cyclone separation unit at the bottom to make the gas-liquid mixture move downward in a high-speed spiral along the inner wall of the cylindrical section 1-1. Centrifugal force is used to throw the denser liquid sodium silicate to the wall and flow downward, while the less dense vapor gathers towards the center and rises. The conical section 1-2 further accelerates the cyclone and improves the separation efficiency. The vortex-breaking component 1-5 above the bottom drain port 1-4 effectively prevents the generation of vortices during liquid discharge, avoids gas from being drawn into the drain pipe, and ensures stable liquid discharge.
[0025] Furthermore, by setting up a gas collection chamber 2 and dividing the gas outlet into three pipelines connected to reactor 200, seasoning tank 300, and pure water storage tank 400 respectively, the waste heat is utilized in stages according to pressure levels: high-pressure steam is directly returned to reactor 200 for auxiliary heating and bottom jet stirring, reducing fresh steam consumption; medium-pressure steam is introduced into the jacket of the seasoning tank to maintain the slurry temperature ≥80℃ through indirect heat exchange, preventing the solidification of high-viscosity slurry and avoiding contamination caused by direct contact between steam and materials; low-pressure steam is introduced into the coil of pure water storage tank 400 to preheat boiler feedwater to 80-90℃, reducing fuel consumption of steam generator 500. This staged utilization method utilizes steam at different pressure levels during the depressurization process "according to quality," maximizing the recovery of waste heat.
[0026] Furthermore, by connecting the seasoning tank 300 to the reactor 200, the prepared slurry is returned to the reactor 200, realizing the recycling of materials such as solid fine powder and filter residue, and improving raw material utilization. By connecting the pure water storage tank 400 to the steam generator 500, and the steam generator 500 to the reactor 200, a closed-loop heat source is formed, further reducing external energy input. The entire system achieves a dual closed loop of "material recycling and heat source circulation," which can reduce production costs. Furthermore, in order to realize the aforementioned waste heat utilization according to pressure level, in one possible implementation, a first pressure valve (not shown in the figure) is installed on the first pipeline, a second pressure valve is installed on the second pipeline, a third pressure valve is installed on the third pipeline, a pressure sensor is installed in the gas collection chamber 2, the pressure sensor is connected to a controller, and the controller is connected to the first pressure valve, the second pressure valve and the third pressure valve respectively. The pressure sensor measures the pressure inside the gas collection chamber 2 and sends the pressure value to the controller; The controller receives the pressure value P and controls the opening and closing of the first pressure valve, the second pressure valve, and the third pressure valve according to the pressure value P, as follows: When the controller determines that the pressure value P > the first threshold P1, it opens the first pressure valve and closes the second pressure valve and the third pressure valve. 2. When the second threshold P2 ≤ pressure value P ≤ first threshold P1, open the second pressure valve and close the first pressure valve and the third pressure valve; 3. When the pressure value P is determined to be less than the second threshold P2, the third pressure valve is opened and the first pressure valve and the second pressure valve are closed.
[0027] The embodiments of the present invention do not specifically limit the aforementioned first threshold P1, second threshold P2 and third threshold P3, which can be adjusted according to actual conditions. For example, the first threshold P1 is 0.35 MPa and the second threshold P2 is 0.2 MPa. To further achieve energy conservation and environmental protection, the structure of the aforementioned reactor 200 will be described below in the embodiments of the present invention.
[0028] In one possible implementation, such as Figure 2 As shown, the reactor 200 includes a reaction vessel body, which is provided with a packing port, a steam inlet and a steam outlet, and the steam inlet is connected to the steam generator 500; The middle stirring output shaft at one end of the reaction vessel is connected to the rotating assembly 600, and the middle output shaft at the other end is a hollow shaft. A T-shaped steel pipe 700 is inserted inside the hollow shaft. The free end of the horizontal tube in the T-shaped steel pipe 700 extends into the interior of the reaction vessel. In one possible implementation, the free end of the horizontal tube is located between the stirring shaft and the inner wall of the reactor 200, and is below the liquid level inside the reactor 200.
[0029] Of course, a sealing packing 800 can also be installed between the horizontal pipe of the T-shaped steel pipe 700 and the hollow shaft. The packing 800 can be made of flexible graphite or graphite-polytetrafluoroethylene composite material, which has self-lubricating and compression resilience, and can adapt to the relative displacement between the lead-out steel pipe and the hollow output shaft extension caused by thermal expansion differences or installation deviations. This packing is used to achieve dynamic sealing between the lead-out steel pipe and the hollow output shaft extension, preventing the leakage of high temperature, high pressure, and strong alkaline gas-liquid mixture in the reactor 200, thereby maintaining pressure.
[0030] The T-shaped steel pipe 700 has six valves installed on its vertical section, and the T-shaped steel pipe 700 is connected to six branch pipes through these six valves; for example... Figure 1 As shown, the six valves are: steam valve, discharge valve, water inlet valve, seasoning valve, pressure gauge valve, and steam recovery valve (corresponding to valves I-VI in the figure respectively); Specifically, branch pipe I is connected to the steam valve and the steam outlet, branch pipe II is connected to the feed inlet 1-3 of the discharge valve, branch pipe III is connected to the water inlet valve and the water storage tank, branch pipe IV is connected to the seasoning valve and the outlet of the seasoning tank 300 (i.e., the seasoning tank 300 is connected to the reactor 200 through the seasoning valve), a pressure gauge is installed on branch pipe V and is connected to the pressure gauge valve, and branch pipe VI is connected to the steam recovery valve and the first pipeline. Thus, by controlling the valves, high-pressure and medium-pressure gases can flow back to the reactor 200 to achieve heat recovery. Example
[0031] This invention provides a collection method based on the energy-saving and environmentally friendly collector 100 used in the production of liquid sodium silicate as described in Example 1. The method includes: The gas-liquid mixture generated by the gas-liquid mixture conveyed by the reactor 200 enters the cyclone separator 1 through the feed inlet 1-3, so that the gas-liquid mixture is separated into gas and liquid. The liquid flows down through the inner wall of the cylindrical section 1-1 and the inner wall of the conical section 1-2, and flows out through the drain outlet 1-4 through the vortex breaker 1-5 for collection. The gas moves upward, enters the gas collection chamber 2 through the demister 2-2, and then returns to the reactor 200 through the first pipe to heat the reacted materials, or enters the seasoning tank 300 through the second pipe to keep the seasoning tank 300 warm, or enters the pure water storage tank 400 through the third pipe to increase the temperature of the pure water entering the steam generator 500.
[0032] Of course, the collector 100 is also connected to the reactor 200 to achieve recycling for further energy saving and environmental protection. The method also includes: Step 1: Add solid sodium silicate and steam into reactor 200 through packing port and steam inlet. Open water inlet valve to add water into reactor 200. Turn on rotating component 600 to make the middle stirring output shaft stir and open steam valve, pressure gauge valve, seasoning valve and steam recovery valve. Step 2: The steam in reactor 200 flows back into reactor 200 through the steam outlet and steam valve. This design can buffer pressure fluctuations and avoid sudden pressure changes from impacting reactor 200. Step 3: After the reaction is complete according to the pressure gauge reading, open the discharge valve to allow the gas-liquid mixture to flow into the feed inlet 1-3; Step 4: The slurry in the seasoning tank 300 flows into the reactor 200 through the seasoning valve, and the gas flowing out of the collector 100 flows back into the reactor 200 through the first pipe and the steam recovery valve.
[0033] The collection method provided in this invention achieves tiered utilization of waste heat according to pressure levels: high-pressure steam is directly returned to reactor 200 for auxiliary heating and bottom jet stirring, reducing fresh steam consumption; medium-pressure steam is introduced into the jacket of the seasoning tank to maintain the slurry temperature ≥80℃ through indirect heat exchange, preventing the solidification of high-viscosity slurry and avoiding contamination caused by direct contact between steam and materials; low-pressure steam is introduced into the coil of the pure water storage tank 400 to preheat the boiler feedwater to 80-90℃, reducing fuel consumption of the steam generator 500. This tiered utilization method maximizes the recovery of waste heat by utilizing steam of different pressure levels "according to quality" during the depressurization process.
[0034] Furthermore, by connecting the seasoning tank 300 to the reactor 200, the prepared slurry is returned to the reactor 200, realizing the recycling of materials such as solid fine powder and filter residue, and improving raw material utilization. By connecting the pure water storage tank 400 to the steam generator 500, and the steam generator 500 to the reactor 200, a closed-loop heat source is formed, further reducing external energy input. The entire system achieves a dual closed loop of "material recycling and heat source circulation," which can reduce production costs. The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
