Environmental protection equipment
The series of rotary sulfur desulfurization dust collectors are developed by our company after years of research and absorption of foreign advanced flue gas treatment technology. They are suitable for the purification treatment of combustion flue gas in small and medium-sized fuel oil, coal-fired boilers, and hot furnaces. Its advantages such as simple operation, basically maintenance-free, good desulfurization and dust removal effects are well received by users. The company has invested a lot of manpower and material resources to apply granite towers, 316L special corrosion-resistant stainless steel high-efficiency cyclone desulfurization and dust removal towers, packed towers and other series of products to the research and development of air pollution prevention and control, and cooperate with environmental protection departments to become Friendly partner for many years.
According to the dust removal method, the bag dust collector can be divided into mechanical vibration bag dust collector, reverse flow dust collector, pulse jet dust collector and rotary. Air ring back blow dust collector based on the actual situation and According to the design requirements, this solution can be designed with a pulse blowing dust remover as the dust removal equipment. The pulse blowing dust remover uses compressed air as the ash sliding power, and uses the pulse injection mechanism to release compressed air in an instant, which induces several times The secondary air is injected into the filter bag at a high speed. The filter bag is inflated sharply, and the bag filter that relies on impact vibration and reverse air flow to ash dust has a strong dusting effect, and its intensity and frequency can be adjusted. , The ash sliding effect is very good. The degree of automation is high, and the glycoside management is convenient. According to the design principle and the characteristics of the smoke composition and temperature, this solution uses oil-proof, waterproof and high-temperature resistant needle felt as the filter material. The basic principle is as follows: the dust-containing airflow enters the foot-shaped filter bag of the bag filter from the bottom through the air pipe for processing. When passing through the pores of the filter material. Push. The dust deposited on the material can fall off the surface of the filter material under the action of back blowing and fall into the ash hopper.
Determine the filter speed VF of the bag filter based on the filter material used in the dust collector, the method of dust removal and the nature of the smoke entering the dust collector,
Select the main components and manufacturing and installation specifications of the VF=0.9Mmin dust collector.
1. The air intake system includes air inlet ducts, air inlet channels, baffles, etc. The dusty flue gas enters the bag chamber evenly through the air inlet channels. The wind speed is reduced, and part of the dust falls directly into the ash hopper, which reduces the load of the filter bag. The airflow from the air inlet must not directly rush into the cloth bag, and a deflector should be installed at the inlet.
2. The pass-through points include filter bags, bag cages, flower plates, etc. Each filter bag is set in a bag cage h. The purpose is to prevent the bag from being crushed, and the flower plate is used to support the bag component and separate the bag compartment and Clean air chamber. It is also used as the overhaul platform of the dust remover system components. The thickness of the flower plate is 6mm. The processing is made by laser cutting. The accuracy of the flower plate hole is guaranteed.
