Description

A kind of dedusting economizer

Technical field:

The utility model relates to a kind of boiler subsidiary engine, especially a kind of dedusting economizer.

Background technology:

In the prior art, dust arrester that boiler is used and coal saving device all are independent settings separately, the tube road connects operation to be used, the problem that this dust arrester and coal saving device exist is that floor space is big, the investment of equipment is many, and the cost of operation is high, and this is the existing in prior technology weak point.

Summary of the invention:

The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of dedusting economizer technical scheme is provided, this scheme is that dust arrester and coal saving device are assembled in the housing, thereby saved floor space, also reduced equipment investment, the cost of operation also reduces greatly.

This programme is realized by following technical measures: include support, advance mouth, exhaust opening, dust arrester and coal saving device, the characteristics of this programme are that described dust arrester and described coal saving device are to be fixed on the described support in a housing, the dirt pocket of described dust arrester connects the economizer water tank of described coal saving device, smoke-box on having on the end face on dirt pocket and the economizer water tank; Describedly advance mouth and communicate with described dirt pocket, deduster is arranged in dirt pocket, the exhanst gas outlet of this deduster communicates with last smoke-box, and the ash hole of deduster is connected with ash-falling chamber, connects ash dropping hopper below the ash-falling chamber; The a plurality of smoke pipes that run through the economizer water tank are arranged in described economizer water tank, and the upper end open of each smoke pipe communicates with last smoke-box, and the lower ending opening of each smoke pipe communicates with the smoke evacuation chamber, and described smoke evacuation chamber communicates with described exhaust opening.The concrete characteristics of this programme also have, and the deduster of described dirt pocket is a plurality of cyclone dust collectors.On described economizer water tank, there are the water inlet and the delivery port that communicate with described economizer water tank cavity to stretch out outside the housing.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, dust arrester and coal saving device are to be fixed on the support in a housing, the dirt pocket of described dust arrester connects the economizer water tank of described coal saving device, smoke-box on having on the end face on dirt pocket and the economizer water tank.Advance mouth and communicate with described dirt pocket, deduster is arranged in dirt pocket, the exhanst gas outlet of this deduster communicates with last smoke-box, and the ash hole of deduster is connected with ash-falling chamber, connects ash dropping hopper below the ash-falling chamber.The a plurality of smoke pipes that run through the economizer water tank are arranged in described economizer water tank, and the upper end open of each smoke pipe communicates with last smoke-box, and the lower ending opening of each smoke pipe communicates with the smoke evacuation chamber, and described smoke evacuation chamber communicates with described exhaust opening.This structure is assembled in dust arrester and coal saving device in the housing, becomes an integral body that has dedusting and economize coal, thereby has saved floor space, so also reduced equipment investment, the cost of its operation also reduces greatly.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings:

Fig. 1 is the part sectional structure schematic diagram of the utility model specific embodiment.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.

Among the figure, 1 is support, and 2 is ash dropping hopper, and 3 is ash-falling chamber, and 4 is dirt pocket, and 5 for advancing mouth, and 6 is cyclone dust collectors, and 7 is last smoke-box, and 8 is housing, and 9 is smoke pipe, and 10 is the economizer water tank, and 11 is exhaust opening, and 12 are the smoke evacuation chamber, and 13 is delivery port, and 14 is water inlet.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

By accompanying drawing as can be seen, the dedusting economizer of this programme has dust arrester and coal saving device, described dust arrester of this programme and described coal saving device are to be fixed on the support 1 in a housing 8, the dirt pocket 4 of described dust arrester connects the economizer water tank 10 of described coal saving device, is being provided with smoke-box 7 on the end face on dirt pocket 4 and the economizer water tank 10.Advance mouth 5 and communicate with described dirt pocket 4, in dirt pocket 4 deduster is arranged, the deduster of described dirt pocket 4 is made up of a plurality of cyclone dust collectors 6.Each exhanst gas outlet of these a plurality of cyclone dust collectors 6 all communicates with last smoke-box 7, and each ash hole of a plurality of cyclone dust collectors 6 all is connected with ash-falling chamber 3, ash-falling chamber's 3 following ash dropping hoppers 2 that connect.The a plurality of smoke pipes 9 that run through economizer water tank 10 are arranged in described economizer water tank 10, and the upper end open of these a plurality of smoke pipes 9 all communicates with last smoke-box 7, and the lower ending opening of each smoke pipe 9 all communicates with smoke evacuation chamber 12, and described smoke evacuation chamber 12 communicates with exhaust opening 11.In addition, on described economizer water tank 10, there are the water inlet 14 and the delivery port 13 that communicate with described economizer water tank 10 inner chambers to stretch out outside the housing 8.
