Large bag dust collector for shaft kiln

Shaft Kiln Large Bag Dust Collector
Shaft Kiln Large Bag Dust Collector Detailed Introduction
Shaft Kiln Dust Collector is a high-end product of Botou Sanrong Environmental Protection Machinery Co., Ltd. After years of continuous exploration, the technology has reached the top level in the country. level and achieved good results in the industry.
Working principle
Pre-separation: The dust-containing gas discharged from the shaft kiln enters the air inlet main pipe in the center of the dust collector through the flue. Under the negative pressure generated by the induced draft fan of the dust removal system, it enters the dust collector evenly above the center of the ash hopper. In each bag chamber of the dust collector, the coarse dust in the dusty flue gas is blocked by the deflector
Detailed introduction of the large bag dust collector in the shaft kiln
The shaft kiln dust collector is a product of Botou Sanrong Environmental Protection Machinery Co., Ltd. The company's high-end products have reached the domestic first-class level after years of continuous technological exploration and have achieved good results in the industry.
Working principle
Pre-separation: The dust-containing gas discharged from the shaft kiln enters the air inlet main pipe in the center of the dust collector through the flue. Under the negative pressure generated by the induced draft fan of the dust removal system, it enters the dust collector evenly above the center of the ash hopper. In each bag chamber of the dust collector, the coarse dust in the dusty flue gas falls directly into the ash hopper due to the obstruction of the baffle and its own gravity, completing the pre-separation of dust.
Filtration: Dust-containing gas enters the filter bag through the hole in the flower plate. The dust is trapped on the inner surface of the filter bag. The dust-containing gas is filtered and purified by the filter bag. The purified gas enters the bag chamber and then passes through the lifting switching valve. The exhaust duct is discharged into the atmosphere by the exhaust fan. This dust collector is a top-exhaust air, negative pressure operated inner filter type dust collector. Dust cleaning methods can be divided into two methods: fixed time and fixed resistance. Scheduled dust cleaning is based on a time program. Each room automatically cleans dust in turn according to adjustable time parameters. The dust collector cleaning cycle is adjustable in six levels within ~ hours. The cleaning time of each room is selected in six levels from seconds to seconds. Timing dust cleaning control is to sample the inlet and outlet pressure difference of the dust collector and convert it into an electrical signal through a differential pressure transmitter to perform dust cleaning. The working process is as follows: Inlet and outlet pressure taking device Differential pressure transmitter Cleaning controller relay In addition to the above two control methods, the solenoid valve cylinder lift switching valve is also equipped with a manual control mechanism, which can manually control normal dust cleaning. For the convenience of operation and management, it is recommended to use regular dust cleaning method. Four-temperature control The flue gas temperature of the vertical kiln generally fluctuates within a range, and the moisture content of the flue gas fluctuates within a % range. In order to prevent condensation in the dust collector and bag burning due to excessive temperature, other vicious accidents occur.
The following measures should be taken in this dust collector system:
(1) Insulation measures must be taken at the air inlet pipe body and ash hopper of the dust collector to prevent condensation in the dust collector.
(2) Install temperature detection and automatic alarm devices at the air inlet and exhaust outlet of the dust collector, and install a cold air inlet device at the air inlet. Once the flue gas exceeds the operating temperature range of the bag dust collector, an alarm will occur and temperature control measures will be automatically taken to ensure the safe operation of the dust collector.
(3) Electric heating and rapping devices are installed on the ash hopper to avoid the problem of forced exposure and dust accumulation due to low temperature.
