Boiler dust collector

First, the structure and principle of the boiler Dust Collector:
The boiler Dust collector mainly consists of the main barrel, the upper water injection trough, the lower overflow hole and the cleaning hole, and its working principle is that the dust air flow is entered into the barrel through the inlet flue. The cylinder is a circular cylinder, and the water from the upper part of the dust collector enters the cylinder, making the inner wall of the whole cylinder forming a layer of water film flowing from top to bottom. The flue gas is cut in the lower part of the cylinder and rotates in the barrel, and the dust gas is always rubbed with the water film on the wall of the cylinder under the action of centrifugal force. The water film is wetted, and the dust flows away from the water to the bottom of the precipitator and drained away from the overflow hole. The bottom of the cylinder bottom is sealed with water sealing grooves to prevent fume from leaking from the lower part, and the cleaning holes are used for cleaning the bottom of the cylinder body. After dedusting, the waste water is discharged from the bottom overflow hole into the sedimentation tank, precipitated and neutralized and recycled. The purified gas is drawn through the upper cone part of the cylinder so as to achieve the purpose of dust removal. If the alkaline water is added to the circulating tank (pH value is greater than 9), the desulfurization effect can be achieved.
Two. Characteristics of boiler dust collector:
The characteristics of the boiler deduster are low cost, easy installation, light weight, lower the price of the dust collector, and it is the ideal boiler matching product for the users.
1. the inner granite is made of natural granite and machined into circular bending plates, and the overall structure is smooth and smooth. It has the characteristics of corrosion resistance, abrasion resistance and high temperature resistance.
The 2. is polypropylene plate, which is resistant to acid and rot, and uses high strength, high temperature, acid and alkali resistant materials.
3. the upper flume is a ceramic structure and ensures no leakage during use.
4. the inlet of the dust collector of the boiler is embedded in the embedded connection. The general steel plate is made into 100mm by the import size. The stone cotton rope is filled around the seam, the flange is exported with flange and the flange size is provided. When the flange is installed, the joint is filled with asbestos rope in the flange butt joint. The air leakage is strictly prevented and the dust removal effect is affected.
Three, the main technical performance and parameters of the boiler dust collector:
Dust removal efficiency: >98%
Desulphurization efficiency: >80%
Export speed of smoke: 18~22m/s
Imported smoke speed: 16~20m/s
A dripper barrel rising smoke speed: 3.5~5.5m/s
Overflow tank static pressure: 2~5mmH2O
Barrel resistance: 70~120mmH2O
Water vapor ratio (a):0.12kg/m3
Water consumption is G water (kg/h):G water =a * Q A is water vapor ratio, Q is hourly treated flue gas m3 /h
Flue gas temperature after dedusting: 50~80 C
Four. Installation
(1) water film desulphurizing dust remover is light in weight. The dust collector foundation should be designed according to the geological conditions of the selected model and installation location, and the foundation must be leveled.
(2) the auxiliary facilities such as water supply system, air duct and sedimentation tank of the dust collector should be co-ordinated and designed in the course of installation and construction.
(4) the overflow section is the key part and must be installed accurately. The water seal level should be <2mm after the irrigation and leveling.
Five. Operation and maintenance
1. before running, fill the tank with clear water and supply water to the dust collector.
2, before running, we should first open the draught fan, and then supply water to the water supply system. When the furnace is stopped, the water supply system should be stopped before closing the draught fan.
During operation, the cylinder is absolutely not allowed to cut off water, regular check whether the overflow channel is unblocked, and at the same time, we should observe the temperature of the flue gas and the resistance of the flue gas regularly.
3, regularly clean up the ash in the sedimentation tank, and keep the cleanliness of circulating water as far as possible.
4. The desulfurization efficiency is more than 80%. The alkali solution must be added to the circulating pool regularly to keep the pH of the circulating water more than 9, so that the acid wastewater in the sedimentation tank and the alkali water added and the precipitated filtration can be recycled.
5, if the boiler dust collector has been running or running for a long time, the upper sink will be washed out, and the clean water source (such as tap water) should be scoured for about an hour, in order to remove the ash in the sink.
