Description

Technical Field

[0001] The invention relates to a closed-circuit unit for cleaning dust from a dust collector and a dust collector. Background Art

[0002] At present, the industry mostly uses bag-type dust collectors (the filter bags are cloth bags) containing several filter bag dust removal units to treat dust-containing gases. The cleaning is carried out in a pulse manner. During cleaning, the pulse valve is opened, and the compressed air in the air bag is ejected through the pulse valve through the small holes on the injection pipe, and then blown into the filter bag through the Venturi tube connected to the end of the injection pipe (each filter bag corresponds to a injection pipe), thereby achieving filter bag cleaning and maintaining the filtering performance of the filter bag.

[0003] Since the filter bags of bag-type dust collectors are cloth bags, their operating temperature is lower than 240°C, and they are not suitable for treating industrial dust-containing gases with temperatures higher than 240°C, especially dust-containing gases with high temperatures of 600-700°C. Therefore, when treating high-temperature dust-containing gases, people replace the material of the cloth bags with high-temperature resistant materials (such as stainless steel and other metals) to adapt to the high-temperature working environment. However, although dust collectors made of stainless steel or high-temperature resistant metal materials can also achieve good dust removal effects, the cleaning effect is poor, especially for slightly sticky high-temperature dust-containing gases. There is basically no cleaning effect during cleaning, and the filter holes on the filter bags are clogged, and dust cannot be effectively removed. Summary of the invention

[0016] In one aspect, the present invention also provides a dust collector.

[0017] The technical solution is: a dust collector, including a dust removal gas inlet, a purified gas outlet, a dust removal chamber, an ash hopper and a cleaning system, a plurality of dust removal units are arranged in the dust removal chamber, a plurality of blow pipes are arranged on the cleaning system, each blow pipe corresponds to a dust removal unit, and a gap is formed between each blow pipe and its corresponding dust removal unit, the dust collector also includes a dust collector closed-circuit system, and the dust collector closed-circuit system is the above-mentioned dust collector closed-circuit system.

[0018] Optionally, the closed-circuit unit is the above-mentioned closed-circuit unit for cleaning the dust collector.

[0019] On the one hand, the present invention also provides a dust collector cleaning method.

[0020] The technical solution is: a dust collector cleaning method, during which the gap formed between each blowing pipe and its corresponding dust removal unit is sealed.

[0021] Principle of the invention:

[0022] The inventor of the present invention has discovered through research in production practice that the cleaning principle of filter bags made of cloth material is as follows: after the air flow enters the filter bag, the difference between the pressure inside the filter bag and the pressure outside the filter bag changes (when the air flow just enters, the pressure inside the filter bag is greater than the pressure outside the filter bag, and then as the gas flows out, the pressure inside the filter bag equals the pressure outside the filter bag). Since the filter bag is made of cloth, the filter bag first expands and then contracts, thereby generating vibration. In addition, the incoming air flow is opposite to the direction of the dust removal air flow, and there is a certain reverse sweeping effect, so that the dust accumulated on the wall of the filter hole of the filter bag falls off and leaves the filter bag, thereby effectively cleaning.

[0023] However, when the material of the filter bag is a high-temperature resistant material (such as stainless steel and other metals), since the material does not expand and contract with the difference between the pressure inside the filter bag and the pressure outside the filter bag, the dust accumulated on the filter hole wall of the filter bag cannot be removed from the filter bag by vibration. Since the diameter of the filter bag is much larger than the diameter of the blow pipe (generally, when the diameter of the filter bag is 160mm, the diameter of the blow pipe is about 42mm), the cross-sectional area of ​​the filter bag is much larger than the cross-sectional area of ​​the blow pipe. Therefore, when the airflow from the blow pipe enters the filter bag and contacts the inner wall of the filter bag, since the gap between the blow pipe and the filter bag opening is much larger than the filter hole area of ​​the filter bag, most of the airflow quickly returns from the gap between the blow pipe and the filter bag opening, and no high-pressure turbulence can be formed in the filter bag to blow the filter hole wall outward, so there is basically no cleaning effect during cleaning.

[0024] Compared with the prior art, the beneficial effects of the inventive principle of the present invention are:

[0025] The present invention seals the space between the blow pipe and the filter bag so that when cleaning, after the airflow from the blow pipe enters the filter bag and contacts the inner wall of the filter bag, there is no gap between the blow pipe and the filter bag opening and the airflow can only be blown out from the filter holes. Therefore, the airflow in the filter bag forms turbulence and forms high pressure. Under the action of the high pressure, the airflow is blown out from the filter holes, so that the dust accumulated on the filter hole walls of the filter bag falls off and leaves the filter bag, thereby achieving effective cleaning.
