The design idea of ​​this solution is based on the principle of saving investment as much as possible. Due to the high concentration of dust generated during the processing of woodworking equipment, the purpose of recovering dust and purifying the exhaust gas is achieved by the explosion-proof and high-efficiency pulsed bag dust removal technology commonly used in the country. All emission indicators meet emission requirements.
1. Upper case: It is composed of a cover plate and an air outlet that can be lifted;
2, in the box: from the porous plate, filter bag device and venturi tube composition;
3, under the box: from the air inlet, hopper and check door composition;
4. Ash discharging system: It is composed of a deceleration device, a ash conveying device and an ash discharging device.
5. Vibrating screen dust collector injection system: It is composed of control instrument, control valve, pulse valve, blow tube, air bag and protective equipment.
There are two important technical and economic indicators of the central woodworking dust removal system dust removal process: first, investment costs, and second, operating costs. The former is a one-time, the latter is regular, and its cumulative number can be several times or even tens of times the former. In addition, the proportion of power consumption and wearing parts is large in operating expenses. Therefore, designing a reasonable cost is very important for reducing operating costs. In the design of this dust removal process, we have innovated in the following aspects compared to other similar equipment;
1. In the precipitator outlet and fan inlet connection we design for soft connection to eliminate the vibration caused by high speed operation of the fan; a muffler is designed at the outlet of the fan to reduce the noise caused by high speed operation of the fan;
2. To facilitate the inspection and observation of the dust collector, we designed an organic glass observation (inspection) door at the bottom of the dust collector hopper; the system pipe is flanged between 4-6 meters, and a maintenance door is designed around 5m; Observe the dust deposition in the pipeline and clean up;
3. The pipe diameter and layout method require all pipelines to be arranged in a unified manner, occupy as little space as possible, strive to be simple, compact, flat and beautiful, and be convenient for installation, operation and maintenance. Set rapid access points where dust easily settles, and make the pipeline system investment and operating costs low on the premise of guaranteeing the use results. Vacuum pipe main pipe is installed in the straight pipe and quick access is installed; the inspection port meets air conditioning and ventilation related requirements. .
4. The main dust box outside the workshop is equipped with a number of explosion explosion windows with bursting discs. When the temperature and pressure inside the dust box rise instantaneously and the pressure reaches the bursting pressure of the bursting disc, the system will forcibly cut off the fan's power supply. An audible and visual alarm signal is issued, and the bursting disc begins to break open, instantaneously releasing the high temperature and high pressure airflow inside the dust collector box to prevent the box body from being affected by the expansion of the high pressure air flow.
5. The dust removal system is equipped with a wind speed sensor at the front, middle and back ends of the main pipeline. The wind speed of the wind pipe is displayed on the display screen of the electric control cabinet in real time. When the spark detector detects sparks in the pipeline, the alarm device emits an audible and visual alarm signal. The system cuts off the fan's power supply, suspends production, and performs maintenance until the sparks are extinguished by the fire protection system and production resumes.
6. Dust trap system is equipped with a dust stopper in the main box body. When the dust in the box reaches the setting position of the stopper, the fan stops operating, suspends production, and displays an alarm on the display screen of the electric control box until the dust is discharged from the dust discharging device. After unloading to the position of the stopper, the production can be restarted. Zui greatly guarantees the service life of the bag and dust removal in the workshop.
7. Each suction port is equipped with a plug-in valve, and automatic plug-in valves are provided for machines with more suction ports or larger suction ports, and manual plug-in valves for small-diameter machines. An inductor is set at the flapper valve to react the valve switch condition to the electronic control system. The electronic control system adjusts the fan power in real time according to the number of the valve switches to achieve the energy saving effect.
Design of wood factory dust collector seal hood:
1, should be in accordance with the distribution of pollution sources, process equipment types and production operations and other conditions, the rational choice of cover form, so that it can not only effectively control the dust without affecting the operation of workers and maintenance of equipment maintenance.
2. Minimize the holes and gaps on the cover, and try to avoid rigid connection to the vibration or reciprocating equipment body to ensure that the airtight cover is strong and tight.
3. According to the process operation requirements, set the necessary working hole, access door and observation hole, the door hole should be tight, convenient assembly and disassembly, opening and closing activities. The opening area should be reduced as much as possible. The opening position should be far from the positive pressure center in the cover. Avoid locations where the air speed is high.
The company's utility model spark arrester features: simple and reasonable structure, can play a role in the capture of sparks, large particles, low resistance, high efficiency, without increasing system resistance, long life, low investment.
