Description
Technical Field
The invention relates to the technical field of ash discharging of filters, in particular to an ash discharging balance device and a filter.
Background
For filtering unstable gases (such as coal gas, yellow phosphorus furnace gas, chlorination furnace gas and the like), ash powder and gas are discharged out of the filter simultaneously during ash discharge, and the ash powder can be discharged out of the system after the unstable gases entrained in the ash powder are replaced for ensuring safety, otherwise, the furnace gas is leaked out, so that safety accidents are caused. Replacement is therefore an indispensable process operation in the case of ash removal by unstable gas filtration.
The existing replacement means is that a balance pipe is erected between a replacement tank and a filter, when ash is required to be discharged, the balance pipe is opened, the replacement tank is communicated with an original air cavity of the filter through the balance pipe, the pressure between the replacement tank and the original air cavity of the filter is the same (or very similar), and then ash can be discharged to the replacement tank under the action of dead weight; simultaneously, injecting replacement gas (usually inert gas) into the replacement tank, so that the gas entering the replacement tank together with the ash powder returns to the original air cavity of the filter through the balance pipe; after the replacement is completed, the ash discharging valve and the balance pipe valve are closed, the replacement tank is separated from the filter, and the ash in the replacement tank can be safely conveyed in a simple mode (such as an ash conveyer). In addition, the replacement tank can cool down the ash powder, so that the safety of the ash powder after being discharged is further ensured.
However, in filtration practice, the stoppage due to the blockage of the balance pipe is not a minority. Some are blocked by ash due to horizontal breakage of the balance pipe, some are blocked due to too small or too long of the pipe diameter of the balance pipe, some are blocked due to phase change caused by poor heat preservation of the balance pipe, and the like. Therefore, the key to reducing parking is to optimize the balance tube design.
Disclosure of Invention
The invention mainly aims to provide an ash discharging balance device and a filter, so as to solve the technical problem that in the prior art, the balance pipe is easy to block to cause stopping.
In order to achieve the above object, a first aspect of the present invention provides an ash discharging balance device, which has the following technical scheme:

Therefore, the invention does not contain a horizontal replacement gas channel, and the blockage risk is obviously reduced; by forming the replacement gas channels which are obliquely and vertically arranged, ash powder falling into the replacement gas channels from the upper part of the taper pipe is very easy to discharge from the lower part of the vertical pipe, so that the replacement gas channels are prevented from being blocked; meanwhile, the second pipe body is arranged in the filter, so that the temperature difference between the second pipe body and the filter is small, and the phase change material is not easy to condense and separate out; the second pipe body is integrally arranged in the filter without a complex pipeline structure, so that the length of the replacement gas channel is far shorter than that of the existing balance pipe, and dust is not easy to accumulate. In summary, the invention has simple and compact structure, is convenient to process and manufacture, has no blockage risk, and can obviously improve the production efficiency.
As a further development of the first aspect of the invention, the second tube body is placed coaxially with the first tube body. Therefore, even ash discharging channels and replacement gas channels can be formed, dead angles are reduced, and the stability of ash discharging is improved.

Therefore, the second valve is simple in structure and good in control effect.
As a further improvement of the first aspect of the invention, a protection mechanism for preventing ash from falling into the replacement gas channel is also included, and the protection mechanism comprises an ash blocking ring arranged at the top of the replacement gas channel. Thereby, the dust is further prevented from falling into the second tube body.

Therefore, the third pipe body is directly in butt joint with the first pipe body and is vertically placed, and ash is prevented from blocking the third pipe body.
As a further development of the first aspect of the invention, the third pipe body has an enlarged section, a vertical section and a reduced section connected in sequence from top to bottom. Therefore, the pipe diameter of the vertical pipe section is larger than that of the first pipe body, the cooling effect on ash powder can be achieved, and the expansion section and the contraction section with slopes are beneficial to rapid unloading of ash powder.
In order to achieve the above object, a second aspect of the present invention provides an ash discharging balance device, which has the following technical scheme:
