Description
Technical Field
The invention belongs to the field of dust removal of dust-containing gas, and particularly relates to a lifting door plate type airflow dust removal bag type dust remover.
Background
At present, the bag type dust collector is widely applied to purifying dust-containing gas generated in industries such as power generation, cement, chemical industry, metallurgy, mine, grain processing and the like. The working principle of the bag type dust collector is that dust-containing gas is introduced into the dust collector and penetrates through a filter bag arranged in the dust collector, and dust particles are intercepted and retained on the surface of the filter bag to form a dust layer. The clean air smoothly passes through the filter bag and flows out of the dust remover. After the bag type dust collector operates for a period of time, the dust layer accumulated on the dust facing surface of the filter bag of the bag type dust collector becomes thicker and thicker, so that the resistance loss of the dust collector is increased. Therefore, after the bag house is operated for a certain period of time, the ash removal is required.
The existing bag type dust collector mainly adopts two modes of pulse blowing dust removal and air pressure back blowing.
The pulse blowing ash-cleaning mode is characterized by that high-pressure air is blown into the filter bag at high speed in a short time (generally less than 0.2 second) to produce back-blowing air flow opposite to filtering air flow so as to make the interior of the filter bag produce pulse expansion vibration and the wall of the filter bag obtain high outward acceleration so as to shake off dust and make the dust layer on the surface of the bag fall off. The long-term and repeated deformation of the filter bag can accelerate the fatigue of the filter bag, and the service life of the filter bag is obviously shortened. The cost of the filter bag occupies a large proportion in the whole dust collector, and the pulse blowing dust cleaning mode increases the loss of the filter bag through the change of the shape of the filter bag, so that the problem that the filter bag is easy to damage is very obvious.
The back-blowing mechanism is an important component of the ash removal system of the large-scale back-blowing bag type dust collector. At present, the back-blowing mechanisms are basically arranged in the dust remover, are limited by a plurality of factors of temperature environment, are easy to leak air through a back-blowing valve, and are easy to break down the machine; in addition, in the actual operation process, due to the constraint of equipment processing precision, installation precision, quality of installation workers and the limitation of a mechanical structure, position deviation often occurs between each positioning back blowing point and each sub-chamber theoretical inlet position, and a large amount of back blowing air volume loss is caused. And the problems of difficult maintenance, high labor intensity and the like.

A guide plate is arranged in a dust cleaning chamber in the dust cleaning mechanism to uniformly distribute the entering back-blowing airflow. The incoming air is distributed more reasonably through the guide plate, the air averagely reaches each cloth bag is balanced, and the ash removal effect is better.
The invention usually only needs one booster fan to provide back-blowing airflow for a plurality of ash-cleaning subchambers, and can also be arranged that the plurality of booster fans correspond to one or a plurality of booster air pipes and are connected with a plurality of booster fan air outlets through connecting pipes, the connecting pipes are provided with stop valves, when a certain booster fan is abnormal, the stop valves are opened, and other booster fans can replace the abnormal booster fan and cannot influence the filtration and ash cleaning of other subchambers.
The ash removal airflow provided by the ash removal mechanism is low-pressure stable airflow, and the low-pressure stable airflow penetrates through the filter bag from the interior of the filter bag and flows to the dust air chamber.
When the bag type dust collector is in a filtering state, the inside of the whole dust collector is in a negative pressure state under the drainage action of the draught fan positioned at the air outlet. The filtered gas stream containing dust particles enters the dust chamber from the gas inlet under atmospheric pressure. The dust particles are blocked by the outer surface of the filter bag when passing through the filter bag, and the filter airflow without the dust particles enters the filter bag and further enters the air purifying chamber. The clean gas filtered by each filter bag is collected in the gas purifying chamber and then flows out from the gas outlet. The flow path of the filtering airflow is from the air inlet to the dust air chamber, then enters the air purifying chamber through the filter bag and finally flows out from the air outlet. This achieves filtration of the dust-laden gas.
When the bag type dust collector needs to clean dust, the dust cleaning mechanism executes action and blows low-pressure stable dust cleaning airflow which lasts for a preset time into a filter bag needing to clean dust. The predetermined time may specifically be 8 seconds to 18 seconds. The pressure of the deashing gas flow is slightly higher than that of the dust-containing gas in the dust chamber, and the pressure difference between the deashing gas flow and the dust-containing gas chamber can be 2000 Pa to 10000 Pa. After the reverse blowing airflow penetrates through the filter bag in a tensioned state, a gasification layer is formed between the dust layer on the outer surface of the filter bag and the filter cloth layer, and the adhesion between the dust layer and the filter cloth layer is damaged. The dust layer on the outer surface of the filter bag immediately slides downwards to the dust collecting hopper under the action of self gravity.
Compared with the bag type dust collector in the prior art, the bag type dust collector has the advantages that the filter bag is in a tensioning state, the pressure of the ash removal airflow is kept stable and the pressure is lower, and the filter bag is static during ash removal. Therefore, the filter bag is hardly damaged during ash removal, and the service life of the filter bag is remarkably prolonged. Meanwhile, the low-pressure stable ash-cleaning airflow replaces the high-frequency pulse back-blowing airflow in the prior art, so that a device for manufacturing the high-frequency pulse back-blowing airflow can be omitted, the equipment is simplified, the cost is reduced, and the running reliability of the equipment is improved.
As shown in fig. 4, the poppet valve is on the upper side when the bag house is in the filtration state. The filtered airflow enters the ash cleaning chamber from the dust chamber and then enters the air purifying chamber.
As shown in FIG. 3, when the pressure difference reaches the set ash removal pressure difference, the booster fan is automatically started to perform airflow ash removal. When the bag type dust collector is used for cleaning dust, the valve of the lift valve is positioned at the lower side. The ash removing airflow enters the ash removing branch chamber from the supercharging air pipe and then enters the dust air chamber through the filter bag. Therefore, the ash removal of the ash removal chambers of the bag type dust collector corresponding to the filter bags is realized.
The ash removing mechanism of the invention realizes the switching between the filtering state and the ash removing state of each ash removing chamber by utilizing the upper position and the lower position of the same lifting door plate type valve,
the ash removal subchambers are mutually isolated and independently operated, the filter of other ash removal subchambers cannot be influenced when any ash removal subchamber is used for removing ash, the structure is simple, and the operation is convenient.
The pressurizing air pipe in the ash cleaning mechanism can also be communicated with the outlet of the induced draft fan connected with the air outlet. The pressure of the purified gas at the outlet of the induced draft fan connected with the air outlet is slightly higher than the atmospheric pressure, and the purified gas can also be used as a gas source of the deashing airflow. Meanwhile, the temperature of the purified gas flowing out of the outlet of the induced draft fan is basically the same as that of the gas in the bag type dust collector, so that an additional heating device is not needed.
Finally, it should be noted that: although the present invention has been described in detail, it will be apparent to those skilled in the art that changes may be made in the above embodiments, and equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
