Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to an ultra-low emission wet dust collector. Background Art

[0002] In the field of environmental protection flue gas dust removal and treatment, bag dust collectors and multi-tube dust collectors are the two most commonly used dust collectors.

[0003] Bag filter uses the filtering effect of fiber fabric to filter dusty gas. When the dusty gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter bag, the dust is retained, so that the gas is purified. At present, bag filters are prone to sticking after being used for a period of time, and need to be cleaned. The cleaning is very inconvenient and requires a lot of manpower and time.

[0004] The multi-tube dust collector removes dust through the centrifugal action of the cyclone, and centrally processes dust through the bottom ash discharge pipe. However, during the sintering process, due to the influence of low temperature, the fine powder particles in the flue gas will adhere to the air guide blades and air guide pipe walls of the multi-tube dust collector along with water vapor, resulting in an increase in the flue gas pressure difference before and after the multi-tube dust collector, a shrinking exhaust air volume, a reduced dust removal efficiency, and substandard emissions. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defects of the above prior art and provide a wet dust collector with thorough dust removal, low water consumption and simple operation and maintenance.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an ultra-low emission wet dust collector, comprising a dust collector body, a dust and gas inlet and a clean air outlet, the dust collector body is provided with a filter assembly on the upper part, and a sewage discharge assembly on the lower part, the dust and gas inlet is opened in the middle part of the dust collector body, the clean air outlet is arranged at the end of the filter assembly, and a fan is installed at the clean air outlet, a dust baffle is arranged at the dust and gas inlet to block dust particles in the dust-laden air, the sewage discharge assembly comprises an inlet valve and a sewage discharge valve, the inlet valve and the sewage discharge valve are respectively installed on both sides of the dust collector body, the filter assembly comprises a filter and a spray assembly, the filter is installed in the dust collector body, and the spray assembly is installed above the filter.

[0007] Furthermore, the dust baffle is configured as a downwardly inclined structure to guide the dust flow toward the lower part of the dust collector.

[0008] Furthermore, the bottom of the dust collector body is configured to be inclined toward one side of the sewage discharge valve, so as to facilitate the discharge of the dirt at the bottom.

[0009] Furthermore, the spraying components are arranged in 6 groups, which can more evenly blow away the powder on the surface of the filter element.

[0010] Furthermore, an inspection door is provided above the dust collector body.

[0011] The utility model is an ultra-low emission wet dust collector, and its beneficial effects are:

[0012] 1. The dusty air enters the dust collector through the dust inlet. The airflow collides with the dust baffle, causing large dust particles to fall directly into the water. The remaining fine dust contacts the water through the dust baffle and is adsorbed by the water. The remaining small part of the dust is filtered through a high-precision filter and discharged into the atmosphere by the fan.

[0013] 2. This dust collector not only overcomes the problem of incomplete dust cleaning and easy bag sticking of bag dust collector, but also solves the problem of substandard emission of multi-tube wet dust collector;

[0014] 3. The dust collector has the characteristics of simple operation and maintenance, low water consumption, low maintenance cost, small footprint and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

The dust collector body 1 is provided with a filter assembly at the upper part and a sewage discharge assembly at the lower part. The dust gas inlet 8 is opened in the middle part of the dust collector body 1, and the clean gas outlet 7 is arranged at the end of the filter assembly. A fan 6 is installed at the clean gas outlet 7, and an inspection door 3 is arranged above the dust collector body 1.

[0022] The dust baffle plate 5 is arranged at the dust inlet 8 to block the dust particles in the dust-laden air. The dust baffle plate 5 is arranged to be a downwardly inclined structure to guide the dust flow to the lower part of the dust collector.

[0023] The sewage discharge assembly comprises a water inlet valve 10 and a sewage discharge valve 9 , and the water inlet valve 10 and the sewage discharge valve 9 are respectively installed on both sides of the dust collector body 1 .
