Description

Technical Field

[0001] This invention belongs to the field of emulsion explosive production technology, specifically relating to an emulsion explosive production process, which is particularly suitable for application on M-type emulsion explosive production lines, and is also applicable to the production of powdered emulsion explosives. Background Technology

[0002] Emulsion explosives are a type of water-containing explosive. They are formed by using an emulsifier to uniformly disperse droplets of an oxidizing agent salt solution in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, thus creating a water-in-oil emulsion explosive. They are a new type of industrial explosive that was developed in the 1970s.

[0003] In the field of industrial explosives, emulsion explosives are widely used in various blasting operations due to their low production cost, high explosive power, and long shelf life. The production process of emulsion explosives includes steps such as preparation of water-oil phase materials, pumping, metering, emulsification, sensitization, loading, and packaging. Among these, emulsification technology is the key to emulsion explosive production. Various performance indicators of emulsion explosives, such as detonation velocity, explosive power, shelf life, and water resistance, are all related to the emulsification effect and are direct factors determining the quality of emulsion explosive products.

[0004] Currently, the emulsification processes used in my country's emulsified explosive production lines include emulsification machine emulsification, pre-emulsification plus static emulsification, and pipeline static emulsification. The pre-emulsification plus static emulsification process adds an extra pre-emulsification and pumping step, while pipeline static emulsification has low capacity and unstable product quality. The production process for M-type emulsified explosives uses emulsification machine emulsification, which involves high-speed emulsification equipment with small rotor-motor clearance, classifying it as Class 0 production equipment and posing safety hazards.

[0005] Chinese patent application 201010150751.3 discloses a process for preparing emulsion explosives. In this process, an aqueous phase from an aqueous phase insulated tank and an oil phase from an oil phase insulated tank are continuously added to an emulsifier via an aqueous phase flow pump and an oil phase flow pump, respectively, for emulsification. An emulsion matrix is ​​produced by the emulsifier, and the temperature of the emulsion matrix is ​​maintained at 90-100°C as it flows out of the emulsifier. The emulsion matrix then flows into a spiral stirrer, where a sensitizer is added according to the formula using a metering pump. However, this emulsion explosive preparation process uses a conventional emulsifier, which suffers from poor emulsification effect, unstable product quality, and low safety.

[0006] To improve the emulsification effect in emulsion explosive production lines, patent 201610722382.8 discloses an emulsion explosive jet emulsification device and method. The emulsion explosive jet emulsification device includes a body and an oil phase inlet, a jet assembly, a water phase inlet, and an outlet, all mounted on the body. This emulsion explosive jet emulsification device has advantages such as simple design, safe operation, continuous emulsification capability, and high mixing efficiency. However, its function is essentially mixing, and the emulsification effect is not ideal. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems existing in the production process of existing emulsion explosive production lines, and to provide a static emulsification method for M-type emulsion explosives that has good emulsification effect, high capacity, and good product quality stability, taking into account the characteristics of high temperature and large capacity of the M-type emulsion explosive production line.

[0008] To achieve the above-mentioned objectives of this invention, the static emulsification method for M-type emulsion explosives of this invention adopts the following technical solution:

[0009] This invention discloses a static emulsification method for M-type emulsion explosives. It employs a specially designed static emulsification device, which comprises an aqueous phase tank, an oil phase tank, an aqueous phase transfer pump, an oil phase transfer pump, two mass flow meters, a Venturi tube, and a multi-stage jet static emulsifier. The aqueous phase tank serves as a storage device for the aqueous phase material, storing the prepared material at a controlled temperature for future use. Similarly, the oil phase tank stores the prepared oil phase material at a controlled temperature for future use. The aqueous phase tank is connected to the inlet of the aqueous phase transfer pump via an automatic discharge valve and a connecting pipe, while the oil phase tank is connected to the inlet of the oil phase transfer pump via another automatic discharge valve and another connecting pipe. The aqueous phase transfer pump... The outlet is connected to one inlet of the Venturi tube via a water-oil phase pipeline, and the outlet of the oil phase delivery pump is connected to the other inlet of the Venturi tube via another water-oil phase pipeline. A mass flow meter is installed on the water-oil phase pipeline connecting the water phase delivery pump and the Venturi tube, and another mass flow meter is installed on the water-oil phase pipeline connecting the oil phase delivery pump and the Venturi tube. The outlet of the Venturi tube is connected to the inlet of the multi-stage jet static emulsifier via a flange. The mass flow meter is a metering device for the water-oil phase material, accurately measuring the instantaneous flow rate and total flow of the water-oil phase material, providing data support for emulsion explosive production and automatic control. The Venturi tube is a mixing device for the water-oil phase material, allowing a small flow rate of oil phase material to flow stably into the main pipeline and initially mix with the water phase material.

[0010] The multi-stage jet static emulsifier is composed of an SK-type static mixing tube, an SK-type static mixing unit, a first jet perforated plate, a jet emulsifying tube, forward spiral blades, a second jet perforated plate, a diaphragm pressure gauge, reverse spiral blades, an SV-type homogenizing mixing tube, an SV-type homogenizing mixing unit, and a pressure relief tube. The number of SK-type static mixing units is 5 to 20, preferably 8 to 16, and they are continuously connected and built into the SK-type static mixing tube. The SK-type static mixing tube is connected to the jet emulsifying tube using a flange connection. The jet emulsifying tube is composed of two connected sections, with the first jet perforated plate and the second jet perforated plate located at the inlet of each section of the jet emulsifying tube, and forward spiral blades... The blades and reverse spiral blades are respectively built into the outlets of each section of the jet emulsification tube and welded to the jet emulsification tube; the diaphragm pressure gauge is connected to the jet emulsification tube by thread, and the pressure gauge is directly installed on the pipeline to display the pressure of this section of the pipeline so as to adjust the pressure drop and balance the emulsification effect of each section of the emulsification tube; the outlet of the jet emulsification tube is connected to the SV type homogeneous emulsification mixing tube by flange; the number of the SV type homogeneous emulsification mixing units is 5 to 20, preferably 8 to 16, and they are continuously connected and built into the SV type homogeneous emulsification mixing tube; the SV type homogeneous emulsification mixing tube is connected to the pressure relief tube by flange; the multi-stage jet static emulsifier is an emulsification device for the production process of emulsified explosives, which emulsifies the water-oil phase material into a colloidal matrix;

[0011] The technical parameters for static emulsification process are as follows:

[0012] ① Aqueous phase temperature 70~110℃;

[0013] ② Oil phase temperature 70~110℃;

[0014] ③ The working pressure of the aqueous phase transfer pump is 0.3~1.2MPa;

[0015] ④ The oil phase transfer pump operates at a pressure of 0.3–1.2 MPa;

[0016] ⑤ Emulsification temperature: 70–110℃;

[0017] ⑥ Measurement accuracy ±0.1kg;

[0018] ⑦ Aqueous phase transfer pump flow rate 1.5~8 m³ / s 3 / h;

[0019] ⑧ Oil phase transfer pump flow rate: 0.5–2 m³ / h 3 / h;

[0020] ⑨ Multi-stage jet static emulsifier with emulsification tube diameter Φ32~110mm;

[0021] ⑩ Production capacity 2~10 m 3 / h.

[0022] The aqueous phase transfer pump is a two-stage screw pump that provides a stable aqueous phase material for the emulsification process during production. The transfer pressure is 0.5–1.2 MPa and the flow rate is 1.5–8 m³.

[0023] The oil phase transfer pump is a two-stage screw pump that provides a stable oil phase material for the emulsification process during production. The transfer pressure is 0.5–1.2 MPa and the flow rate is 0.5–2 m³.

[0024] The diaphragm pressure gauge is a pressure measuring device that provides support for automatically monitoring production dynamics and adjusting production processes.

[0025] Furthermore, the SK-type static mixing tube has a diameter of Φ32~110mm and a length of 500~1000mm.

[0026] Furthermore, the SK-type static mixing unit is assembled from single spiral blades that twist left and right. Its main function is to mix oil and water phase materials together to provide a uniform mixture for emulsification. The twist angles are 180° and 270° respectively, and the length of a single SK-type static mixing unit is 30-100mm.

[0027] Furthermore, the outer diameter of the first / second jet porous plate is 40–110 mm, the number of jet holes on the first / second jet porous plate is 50–300, and the diameter of the jet holes is 1.0–10.0 mm, preferably 2–4 mm; the spacing between adjacent jet holes is preferably 2–10 mm, preferably 4–8 mm; the size and number of jet holes on the jet plate are determined according to the flow rate of the mixture and the pressure required for emulsification of the oil-water phase materials, and different sized holes are designed according to the fluidity of the mixture to ensure that the pressure drop in each section is balanced and the emulsification is uniform.

[0028] Furthermore, the number of jet holes on the first jet porous plate / second jet porous plate is 50 to 300.

[0029] Furthermore, the SV-type homogenizing mixing tube has a diameter of Φ32~110mm and a length of 500~1000mm. The SV-type homogenizing mixing unit is assembled from corrugated sheets rolled from metal plates. The length of a single SV-type homogenizing mixing unit is 30~100mm. Adjacent mixing units are installed at a certain angle to allow the emulsion matrix to flow in different directions on multiple parallel planes. This allows the emulsion matrix to collide and shear during the flow process, thereby achieving the purpose of re-emulsification and homogenization.

[0030] Furthermore, the pressure relief pipe is a large-section empty pipe. After the emulsified matrix passes through the homogenization mixing pipe, it has a certain pressure. After entering the pressure relief pipe, the flow area suddenly increases, which can reduce the fluid velocity and improve production safety.

[0031] The static emulsification method for M-type emulsion explosives of this invention, after adopting the above technical solution, has the characteristics of constant working pressure, stable emulsification quality, and high production line safety, and specifically has the following beneficial effects:

[0032] (1) Using water phase transfer pumps and oil phase transfer pumps can provide stable water and oil phase materials for the emulsification process, ensure a reasonable water and oil phase material ratio, make the emulsification process continuous and stable, and provide stable working pressure to provide energy for static emulsification; using mass flow meters can accurately record the instantaneous flow rate and total flow rate of water and oil phase materials, providing a basis for adjusting production parameters.

[0033] (2) For the first time, it integrates multiple functions such as SK-type static mixing, multi-stage jet emulsification and SV-type homogeneous mixing, and combines forward mixing, reverse mixing, jet shearing and impact collision into one, which greatly improves the emulsification effect of explosives and product performance indicators.

[0034] (3) Using the SK type static mixer can premix the water and oil phase materials, which is beneficial to uniform emulsification.

[0035] (4) The use of multi-stage jet emulsification pipes is beneficial for water-oil phase materials to generate strong shearing and collision under the action of high-energy jet fluid, so as to achieve the purpose of rapid emulsification and strong emulsification.

[0036] (5) Using forward spiral blades and reverse spiral blades can mix the emulsion multiple times, making the emulsion more uniform.

[0037] (6) Using SV type static mixing emulsion tubes, the emulsion fluids flow in opposite directions on multiple parallel planes, thereby causing the emulsion fluids to impact each other in the tube, achieving the purpose of strong shearing and fine emulsification, which is conducive to the mutual shearing, collision and mixing of the emulsified matrix to form a uniform and stable emulsion matrix.

[0038] (7) Using a large cross-section pressure relief pipe is beneficial to release excess pressure, so that the outlet matrix flows stably at a low speed and improves the inherent safety of the production line.

[0039] (8) Using a diaphragm pressure gauge is beneficial for accurately displaying pipeline pressure, so as to adjust the pressure drop at each level and make the emulsification pressure distribution at each level more reasonable. Attached Figure Description

[0059] (11) Production capacity 2-10 m 3 / h.

[0060] The process of the static emulsification method for M-type emulsion explosive of the present invention is as follows:

[0061] S1 Ingredients: According to the requirements of the production process, prepare the aqueous phase material in the aqueous phase tank 12, stir it evenly, maintain a certain temperature, and set it aside. The temperature of the aqueous phase material is 70-110℃. Prepare the oil phase material in the oil phase tank 13, stir it evenly, maintain a certain temperature, and set it aside. The temperature of the oil phase material is 70-110℃.

[0062] S2 Water and Oil Phase Material Conveying: The automatic discharge valves of water phase tank 12 and oil phase tank 13 are opened by the automatic control system. Water phase material enters water phase transfer pump 14, and oil phase material enters oil phase transfer pump 15. Water phase transfer pump 14 and oil phase transfer pump 15 are started to transport water and oil phase materials. The flow rate of water phase transfer pump 14 is 1.5~8 m³ / s. 3 / h, oil phase transfer pump 15 flow rate 0.5~2 m³ / h 3 / h, working pressure 0.3~1.2MPa;

[0063] S3 Water and oil phase material metering: Water and oil phase materials are metered by mass flow meter 16. Mass flow meter 16 accurately measures the instantaneous flow rate and total flow of water and oil phase materials with a metering accuracy of ±0.1kg. The signal is fed back to the automatic control center to provide technical support for adjusting production parameters.

[0064] S4 Mixing and emulsifying:

[0065] ① Mixing: The water-oil phase material delivered from the water-oil phase transfer pump enters the SK type static mixing pipe 1. Under the action of multiple SK type static mixing units 2, the fluids collide with each other in multiple directions, forming turbulence, so that the water-oil phase material is mixed evenly.

[0066] ②Jet Emulsification: The water-oil phase mixture flowing out of the SK-type static mixing pipe 1 forms a pressure drop at the first jet porous plate 3, generating a jet. The high-energy jet causes the water-oil phase mixture to rub, shear, and collide, forming an emulsion. The emulsion rotates and mixes under the action of the forward spiral blade 5. The emulsion flow forms a pressure drop at the second jet porous plate 6, generating a jet again. The emulsion is sheared, collided, and emulsified again, forming a basically stable emulsion matrix. Under the action of the reverse spiral blade 8, it is reverse impacted and mixed to form an emulsion.

[0067] ③ Uniform emulsification: The emulsion, which has been emulsified multiple times, enters the SV type homogeneous emulsion mixing tube 9. Under the action of the SV type homogeneous emulsion mixing unit 10, the high-speed flowing emulsion flows in opposite directions on multiple parallel surfaces, causing the emulsion fluids to impact each other in the tube and undergo strong shearing to achieve fine and uniform emulsification, forming a high-quality emulsion matrix.

[0068] S5 Pressure Release: Due to the high pipeline conveying pressure, the emulsified matrix still has a certain spraying ability after emulsification. In order to improve the safety of the production line, the high-quality emulsified matrix enters the pressure relief pipe 11, and the excess pressure is released to form a stable colloid outflow.

[0069] S6 Pressure Detection: Diaphragm pressure gauge 7 is connected to jet emulsion tube 4 to display the pressure inside jet emulsion tube 4, providing a basis for adjusting the production capacity of emulsion explosives.
