The invention discloses a liquid spraying fermentation tower provided with a non-woven fabric filling system. The liquid spraying fermentation tower comprises a tower body, wherein a return spray plate is disposed on the top portion in the tower body, a filling system is disposed on the upper portion in the tower body, a fermentation liquid is disposed on the lower portion of the tower body, and a false bottom is disposed between the filling system and the fermentation liquid. The filling system is the non-woven fabric filling system. The non-woven fabric filling system is employed and the orientation movement of the non-woven fabric is utilized, so that bacterial cellulose and bacterial cellulose membrane system aggregated thereby, which are produced by fermentation production of liquid sprayed vinegar, are taken away. The problem is thoroughly solved that membranes block the gaps in the filler and then the fermentation production of vinegar is terminated because of the failure of normal flow of the air and the fermentation liquid. Because high value of the bacterial celluloses is determined by functionality of the bacterial celluloses, the non-woven fabric filler overgrowing with the bacterial celluloses can be sold as a specific commodity or developed secondarily and processed elaborately, so that the cost for buying the non-woven fabric filler is made up, and thus cost is substantially saved and a new profit is brought.

The invention discloses a connected graphite crucible applied to producing vanadium-nitrogen alloy products. The connected graphite crucible comprises a crucible body and a push plate. The crucible body and the push plate are of an integrated structure, wherein the crucible body and the push plate are perpendicular to each other and are coaxially connected. A coaxial crucible cavity is formed in the crucible body, and a coaxial push plate cavity is formed in the push plate. The top of the crucible cavity is flush with the top of the crucible body, the bottom of the crucible cavity is communicated with the top of the push plate cavity, and the bottom of the push plate cavity is located between the bottom of the crucible body and the bottom of the push plate. Preferably, the crucible body, the crucible cavity, the push plate and the push plate cavity are all cuboids. Both the crucible body and the push plate are made of graphite. By the aid of the design, the uniformity of force-bearing points can be guaranteed when the push plate and the crucible body are stressed, the defects such as front-back arching caused by dislocation are overcome, and no gas layer separation exists in the connecting position of the crucible body and the push plate. Heat conduction efficiency is high, the service life is long, and batch manufacturing is easy.

The present invention provides a filtering method and a filter. Data in data storage units in a register is input in parallel to vector storage units of a processing module, wherein the number of the vector storage units where data is input is equal to that of the data storage units; and the input data is calculated to obtain a filtering output result, so that each vector storage unit in the processing module is fully utilized, and the utilization of the processing module is improved. In the present invention, data in each data storage unit is arranged in columns, and the columns of data pass through K channels sequentially and are input to the vector storage units, wherein the value of K is the number of filter coefficients; and during data input, the data is offset and stored in ascending or descending order according to the sequence of the channels. Therefore, the unit utilization of the processing module is improved; and the filter can be reconstructed, is adjustable in the degree of parallelism, and uses a few on-chip resources.
