Abstract
The utility model provides a tail gas collecting device of a high-temperature sintering furnace. The tail gas collecting device comprises a liquid ring pump and a postpositional filter unit which is connected with the liquid ring pump through a pipeline. The postpositional filter unit is composed of more than two liquid containers which are communicated with each other in series. Filter screens are arranged at the connector between two adjacent liquid containers. A first-level container of the postpositional filter unit is directly connected with an exhaust port of the liquid ring pump through the pipeline. A final-level container along the liquid flow direction is connected with a water suction pump through the pipeline. The other end of the water suction pump is connected with a feed liquid inlet of the liquid ring pump through the pipeline. Volatile matters in a furnace chamber of the high-temperature sintering furnace enter the liquid ring pump, suspend in the water, and then are brought out along with exhaust air of the liquid ring pump and a portion of water. Next, the volatile matters enter the first-level container and then filtered through filtering and precipitating of the filter screens. Purified water does not contain impurities and can be supplied to the liquid ring pump through the water suction pump to be used as a working medium. Water resources are saved.

The exhaust collection equipment of high temperature sintering furnace of the present utility model, with the volatile matter that produces in the high temperature sintering furnace furnace chamber by after the filtration of pre-filtering device, under the pump drainage of vacuum unit, the unfiltered volatile matter of part, enter liquid rotary pump, volatile matter is suspended in the working media of liquid rotary pump---in the water, the liquid rotary pump next stage is provided with the filter that links to each other by pipeline with described liquid rotary pump, this filter is for to be composed in series by the liquid container that is connected more than two, be provided with filter screen at the adjacent container interface, described first order container is connected by pipeline with the liquid rotary pump exhaust outlet, when liquid rotary pump is worked, enter this from the water that the liquid rotary pump exhaust outlet is taken out of by pipeline along with the liquid rotary pump exhaust, by filtration from level to level, the volatile matter that suspends in water is filtered out, enter at last in the described afterbody container, water in this container has not contained impurity at this moment, by the suction pump that is attached thereto, the water suction that will not have impurity is supplied with liquid rotary pump by the supply opening of liquid rotary pump and is recycled as working media, thereby realize the recycling of resource, saving water resource.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, a kind of embodiment of exhaust collection equipment of high temperature sintering furnace comprises pre-filtering device, vacuum unit and rearmounted filter.
The pre-filtering device of present embodiment is the dewaxing tank 3 for the higher boiling volatile matter of collecting furnace chamber 1 generation.The flue of furnace chamber 1 is by vacuum valve 2 access dewaxing tanks 3 entrances.
The vacuum unit is comprised of lobe pump 4, gauge valve 5, atmosphere injection valve 6 and liquid rotary pump 7.Lobe pump 4 air inlets are connected by pipeline with 3 outlets of dewaxing tank, the air inlet of the exhaust outlet of lobe pump 4, gauge valve 5, atmosphere injection valve 6 and liquid rotary pump 7 is successively by pipeline series connection, and the exhaust outlet of liquid rotary pump 7 passes into rearmounted filter outside the workshop by pipeline---in the settling tank 8.Adopt lobe pump series connection atmosphere injection valve and liquid rotary pump to form the vacuum unit, improve the final vacuum of vacuum unit, more thoroughly the volatile matter in the pump drainage furnace chamber 1.
Described rearmounted filter is for to be separated into two-part settling tank 8 by filter screen 9.The described first order is filtering ponds 81, described afterbody is another part clarifier-tank 82 of settling tank 8, the exhaust outlet of liquid rotary pump 7 directly passes in the filtering ponds 81 by pipeline, filtration by filter screen 9, water after the filtration flows in the clarifier-tank 82, therefore the water in the clarifier-tank 82 does not contain the volatile matter that pumps out in the furnace chamber 1, can continue to recycle as working media for liquid rotary pump 7.
Adopting suction pump 11 constantly the water in the clarifier-tank 82 to be supplied with liquid rotary pump 7 in the present embodiment recycles as working media.Suction pump 11 1 ends are provided with valve 10, and by in the pipeline access clarifier-tank 82, the other end is connected by the supply opening of pipeline with liquid rotary pump 7.
