What kinds of dust removal systems are there in the intermediate frequency melting furnace ?
1. Smelting furnace dust removal air intake system
The air intake system includes an air inlet, an inlet throttle valve, a wind deflector, a wind deflector, a distribution screen, etc., and the dusty airflow enters each bag room through the conveying pipe, the wind speed is reduced, and most of the dust directly falls into the ash bucket, reducing the filter bag. The load; the unreceived dust and the flue gas enter the bag chamber through the distribution screen through the air deflector, filling the entire space, and the windshield and the distribution screen ensure that the dusty air flow and the clean air flow flow upward along the filter bag direction. If the owner requests that the equipment be manufactured for online cleaning, the movement of such airflow can greatly reduce the secondary fly ash during the cleaning.
2. Melting furnace dust removal and ash system
Including filter bags, bag cages, flower boards, etc., each filter bag is placed on a bag cage, in order to prevent the bag from being crushed, and the flower plate is used to support the filter bag assembly and the compartment and the clean room, and as Overhaul platform for components of the dust collector filter system.
3. Melting furnace dust removal and cleaning system
Including net air pipe, compressed air pipe, pulse valve, poppet valve, venturi, etc., the net air pipe is arranged in parallel in the pre-assembled top air purifying chamber, and each net air pipe has a number of small air nozzles, these small air nozzles One to one corresponds to the venturi on each filter bag. The net air pipe is connected to the external compressed air pipe, the beginning of the pipe is inserted into the card slot, the end is welded with the support angle steel, and the pipe clamp is used for positioning. A compressed air duct is installed at the top of the precipitator, and the duct is connected to the net air duct. The compressed air is controlled by a pulse valve, and the pulse valve is connected with the solenoid valve. The operation of the whole set of cleaning system is controlled by the control system of the dust collector. The sensor for detecting the differential pressure at both ends of the dust collector is fixed at the outlet and the inlet of the air pipe, and the cleaning cycle of the dust collector is controlled according to the differential pressure signal detected by the differential pressure gauge.
4. Melting furnace dust removal and exhaust system
It includes a dust collector purification gas discharge system composed of an outlet throttle valve and an exhaust pipe.
5. Smelting furnace dust removal system
The dust discharge device adopts the single-point unloading method of humidifying the scraper conveyor + double-screw humidifier. The dust-removing equipment includes: 8 star-type ash discharge valves , 2 first-stage scraper conveyors , and 1 humidifier . When the ash discharge is started, the star type ash discharge valve, the first stage screed conveyor, the first stage screed conveyor, and the humidifier are sequentially turned on, and the ash buckets cannot be unloaded at the same time.
6. Melting furnace dust control system
The electrical control part is the command center of the whole dust removal system. Whether the control part is reliable or not will directly affect whether the dust removal system can work normally. Therefore, the electrical control system should meet the process requirements, the operation is stable and reliable, safe and economical, simple in operation and convenient in maintenance.
