Description

Technical Field

[0001] This utility model relates to the field of air dust removal technology, specifically a high-efficiency dust suppression and explosion suppression water cyclone dust removal system based on cyclone enhancement. Background Technology

[0002] In industrial production (such as polishing, grinding, deburring, and shot blasting of aluminum, magnesium, titanium, zinc, copper, iron, and stainless steel metals, which generate flammable and explosive dust), a large amount of dust is produced. This dust not only seriously pollutes the working environment and harms the respiratory health of operators, but also poses significant safety hazards. When flammable and explosive dust (such as coal dust, aluminum dust, and plastic dust) reaches a certain concentration in the air, it can easily cause a dust explosion when exposed to a source of ignition, resulting in equipment damage and personal injury. Therefore, efficient integrated dust suppression and explosion suppression has become the core requirement for industrial dust control. Currently, commonly used dust treatment equipment in the industrial field mainly includes bag filters, electrostatic precipitators, and traditional water dust removal equipment (such as spray towers and simple water film dust collectors). However, existing dust removal equipment has insufficient dust removal efficiency, poor fine dust collection effect, low water resource utilization, and poor maintenance convenience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high-efficiency dust suppression and explosion suppression water cyclone dust removal system based on cyclone enhancement. It has multiple dust removal functions, improves the dust removal effect, has a significant effect on the capture of fine dust, recycles wastewater to avoid water waste, and is easy to maintain. It can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency dust suppression and explosion-proof hydrocyclone dust removal system based on cyclone enhancement includes a dust collection box. The top surface of the dust collection box is equipped with a purified air outlet and a working indicator light. An explosion-proof motor is fixedly installed inside the purified air outlet. The output end of the explosion-proof motor is connected to a fan located at the top of the dust collection box's inner cavity to drive airflow circulation within the dust collection box. An explosion-proof control box and a main inlet explosion-proof box are respectively located on the upper part of the outer side of the dust collection box. A dust inlet is opened on one side of the dust collection box, and a circulation pool is connected to the lower part of the other side of the dust collection box. The inner cavity of the circulation pool is divided into a filter chamber and a circulation chamber. The circulation chamber and the lower part of the dust collection box are connected to facilitate the recovery of wastewater. A secondary filter box is installed in the circulation chamber, and the outlet end of the secondary filter box is connected to the filter chamber for graded filtration of the recovered wastewater. A wastewater circulation pump is installed in the filter chamber, and the wastewater circulation pump is connected to an inlet circulation pipe. A flow switch is installed on the inlet circulation pipe. To facilitate the detection of water pump output flow, the inner wall of the dust collector is equipped with an overflow trough. The side of the overflow trough is connected to the end of the inlet circulation pipe. A water curtain wall panel, which is inclined downwards on the left side of the overflow trough and cooperates with the dust inlet, is used to initially intercept the incoming dust-laden airflow with a water curtain. The bottom of the water curtain wall panel is connected to the upper component of the water mist separation fang. A water vortex guide plate is provided between the front and rear inner walls of the dust collector and below the upper component of the water mist separation fang. A water mist separation backflow plate is installed on the upper surface of the water vortex guide plate. A water mist separation fang lower component is provided on the upper surface of the water mist separation backflow plate. The separation of water mist and dust is enhanced by the cooperation of the upper component of the water mist separation fang, the lower component of the water mist separation fang, and the water mist separation backflow plate. A water vortex generating plate is provided between the front and rear inner walls of the dust collector and to the right of the water vortex guide plate and the water curtain wall panel to generate a vortex field to enhance the dust removal effect.

[0005] As a preferred technical solution of this utility model, a cleaning door is installed on each of the left and right side walls of the dust collector to facilitate internal cleaning and maintenance of the equipment. A water vortex effect observation window is installed on each of the front and rear side walls of the dust collector to observe the water vortex flow field morphology and dust removal process in the dust collector in real time.

[0006] As a preferred technical solution of this utility model, a water vapor isolation filter box is installed in the upper part of the inner cavity of the dust collector and at the lower part of the fan, which is used to further intercept residual water vapor in the exhaust airflow. The outer side of the dust collector is provided with a water vapor isolation filter box inlet and outlet window that cooperates with the water vapor isolation filter box, so as to facilitate the disassembly, assembly and replacement of the filter box.

[0007] As a preferred technical solution of this utility model, a water level sensor is connected to the upper part of the inner cavity of the circulation tank for real-time monitoring of the water level in the circulation tank, and a water level control cable protection pipe that cooperates with the water level sensor is provided on the outer side of the dust removal box for protecting the connecting cable for water level monitoring.

[0008] As a preferred technical solution of this utility model, the tooth structure of the lower component of the water mist separation is located above the tooth structure between the water mist separation backflow plate and the upper component of the water mist separation, and a dust flow channel is formed between the lower component of the water mist separation and the latter two, which guides the dust-laden airflow to fully contact the tooth structure and enhances the water mist separation effect.

[0009] As a preferred technical solution of this utility model, a water vortex size adjustment component is installed on the upper part of the left side of the water vortex generating plate. By adjusting the adjustment component, the intensity of the water vortex flow field can be changed to adapt to different dust concentration conditions.

[0010] As a preferred technical solution of this utility model, a water replenishment control valve is provided on the upper side of the filter chamber for replenishing clean water to the filter chamber to maintain the water circulation volume. An overflow hole is provided on the upper side of the circulation chamber for discharging excess sewage in the circulation chamber. A water outlet pipe is installed at the bottom of the circulation chamber for emptying the sewage in the circulation chamber when the equipment is stopped.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. High dust removal efficiency and strong adaptability: It adopts a three-stage dust removal structure of "water curtain interception + cyclone centrifugation + serrated component separation", covering the full range of large and fine dust capture. The dust removal efficiency is significantly better than traditional single dust removal methods. The water cyclone size adjustment component can flexibly adapt to different dust concentration conditions (such as grinding, shot blasting, polishing, deburring and other different scenarios), avoiding the decline in dust removal effect due to fluctuations in dust concentration. 2. Excellent explosion suppression safety performance: The core components of the system (explosion-proof motor, explosion-proof control box, and explosion-proof main incoming line box) are all designed to be explosion-proof. Combined with the "wet environment" formed by water curtain and water circulation, it can effectively suppress the risk of dust explosion and meet the safety requirements of flammable and explosive dust sites. The whole process is a closed dust removal system (with no open design from dust inlet to purified exhaust outlet), which avoids leakage of dust-laden airflow and reduces secondary dust and explosion hazards. 3. Water resource recycling is economical. The recycling pool adopts a closed-loop design of "recycling chamber - secondary filter box - filter chamber - sewage circulation electric pump" to achieve filtration and reuse of dust removal sewage, improving water resource utilization rate by more than 60% and significantly reducing industrial water costs; the linkage control of water level sensor and water replenishment control valve avoids water waste and reduces sewage discharge. 4. Convenient maintenance and stable operation: The design of the cleaning door, water vapor isolation filter box inlet and outlet window, and water swirl effect observation window facilitates internal cleaning, component replacement, and operational status monitoring, reducing downtime for maintenance; monitoring components such as flow switch and water level sensor adjust system parameters in real time, avoiding equipment failures caused by abnormal water volume or level, and extending equipment lifespan. 5. Compact structure and wide applicability: The integrated design of each component (dust collection box, circulation pool, filtration system) results in a small footprint and allows for flexible installation in various locations such as workshops and production lines. With a full-range dust removal capability from large particles to fine dust, it can be widely used in dust control in multiple industries such as mining, coal processing, metal smelting, and building materials production, with an applicability far exceeding that of traditional dust removal equipment.

The outer side of the dust collector box 1 is provided with a water vapor isolation filter box inlet and outlet window 4 that cooperates with the water vapor isolation filter box 24.

[0026] A water level sensor 15 is connected to the upper part of the inner cavity of the circulating pool 27, and a water level control cable protection pipe 11 that cooperates with the water level sensor 15 is provided on the outer side of the dust removal box 1.

[0027] The tooth structure of the lower component 21 of the water mist separation is located above the tooth structure between the water mist separation backflow plate 18 and the upper component 19 of the water mist separation, and a dust flow channel is formed between the lower component 21 of the water mist separation and the latter two.

[0028] A water vortex size adjustment component 22 is installed on the upper part of the left side of the water vortex generating plate 17.

[0029] A water supply control valve 29 is provided on the upper side of the filter chamber, an overflow hole 26 is provided on the upper side of the circulation chamber, and a water outlet pipe 31 is installed at the bottom of the circulation chamber.

[0030] Working principle: This system achieves efficient dust and explosion suppression through an integrated process of "airflow guidance - multi-stage dust removal - water curtain interception - cyclone enhancement - water vapor separation - wastewater circulation". The specific operation process is as follows: During the start-up phase of airflow and water circulation, the water level in the dust collector 1 should be higher than the water mist separation component 19. After the system is started, the explosion-proof motor 25 drives the fan 10 to operate, creating a negative pressure environment in the dust collector 1, which in turn raises the water level on the right side and lowers the water level on the left side. The dust flow channel opens, and the dust-laden airflow is drawn into the dust collector 1 through the dust inlet 9. At the same time, the sewage circulation pump 16 in the filter chamber of the circulation tank 27 is started, and the clean water (or circulating water) filtered by the secondary filter box 28 is transported to the overflow tank 23 on the inner wall of the dust collector box 1 through the water inlet circulation pipe 12. The flow switch 14 adjusts the water supply in real time to ensure stable water circulation.

[0031] The first-stage water curtain intercepts and removes dust. The water in the overflow tank 23 flows down evenly along the left-side inclined water curtain wall panel 30 to form a continuous water curtain wall, which comes into direct contact with the dust-laden airflow entering from the dust inlet 9. Large dust particles in the airflow are directly captured by the water curtain wall and flow downward with the water.

[0032] Secondary cyclone enhanced dust removal: The dust-laden airflow (still containing fine dust) after preliminary dust removal by the water curtain enters downward into the area formed by the water cyclone guide plate 20 and the water cyclone generator plate 17; The water swirl generating plate 17 generates a stable swirling field. With the water swirl size adjustment component 22, the swirling intensity can be adapted according to the dust concentration. The airflow generates centrifugal motion under the action of the swirling flow. Fine dust is thrown to the outside of the airflow and comes into contact with and is captured by the water film (formed by the water adhering to the surface of the component during the water circulation process). Meanwhile, the upper component 19 and the lower component 21 of the water mist separation fang, together with the water mist separation backflow plate 18, form an interlaced dust flow channel. The upper and lower cooperation of the fang structure between the three further tears the water mist in the airflow, so that the residual dust and water mist can fully collide and condense. The water dust isolation baffle 13 prevents the water mist-laden air flowing out between the water vortex generating plate 17 and the water curtain wall plate 30 from directly rushing towards the water vapor isolation filter box 24.

[0033] Water vapor separation and purification of exhaust gas: The airflow that completes dust removal moves upward and first passes through the upper water vapor separation component 19, the lower water vapor separation component 21, and the water vapor separation backflow plate 18 for secondary water vapor separation. Then, it passes through the water vapor isolation filter box 24 located at the bottom of the fan 10 to intercept the residual trace water vapor and extremely fine dust in the airflow. Finally, the purified air is discharged through the purified air outlet 7, the working indicator light 8 displays the system operating status in real time, and the explosion-proof control box 5 and the main incoming line explosion-proof box 6 ensure explosion-proof safety throughout the entire process.

[0034] Wastewater recycling and maintenance: Wastewater in the recycling chamber is filtered by the secondary filter box 28 and then enters the filter chamber to realize the recycling of water resources; The water level sensor 15 monitors the water level of the circulation tank 27 in real time and transmits the signal through the water level control cable protection pipe 11. When the water level is too low, the water replenishment control valve 29 replenishes clean water to the filter chamber. The overflow hole 26 at the top of the circulation chamber discharges excess sewage, and the outlet pipe 31 at the bottom can drain the sewage when the equipment is stopped. During routine maintenance, the inside of the dust collector box 1 can be cleaned through the cleaning door 2, the water vapor isolation filter box 24 can be replaced through the water vapor isolation filter box inlet / outlet window 4, and the internal swirling and dust removal effect can be observed through the water swirl effect observation window 3 to ensure long-term stable operation of the equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
