The invention discloses a rotary kiln outer drum waste heat collecting system which comprises a rotary kiln, a temperature detection device, a grate cooler, a coal grinder and a waste heat collecting system body, wherein the temperature detection device is used for detecting the temperature of the rotary kiln, and the grate cooler, the coal grinder and the waste heat collecting system body are connected or disconnected through opposite valves arranged on pipelines. An outer drum of the rotary kiln is provided with a heat collecting cover, a supporting frame used for supporting the heat collecting cover, and a hot air duct used for collecting heat collected by the heat collecting cover. The heat collecting cover comprises a cover body and flow guide plates arranged in the cover body, the flow guide plates are composed of transverse flow guide plates and longitudinal flow guide plates in a crossed mode, the transverse flow guide plates are provided with flow guide holes, the hot air duct is provided with a through pipe communicated with the cover body, and one end of the hot air duct is communicated with the pipelines of the grate cooler, the coal grinder and the waste heat collecting system body and is connected or disconnected with the grate cooler, the coal grinder and the waste heat collecting system body through the opposite valves. The rotary kiln outer drum waste heat collecting system has the advantages of being simple in structure, low in weight, safe, easy to produce, and capable of transmitting heat to multiple systems by effectively using the waste heat on the surface of the rotary kiln.

The invention discloses a method for collecting a gas sample and/or a liquid sample in an anaerobic fermentation system. The method comprises the following steps: hermetically connecting a three-way pipe with the outlet of the anaerobic fermentation system through a pipeline, and collecting samples through the following step (1) and/or step (2), wherein in the step (1) the on and off of the three-way pipeline is controlled to ensure that the inlet pipeline of the three-way pipe is communicated with at least one outlet pipeline and the outlet pipeline of the three-way pipe is connected with a gas collecting device, so that the collection of gas samples in the anaerobic fermentation system is realized; in the step (2), the on and off of the three-way pipe is controlled to ensure that the inlet pipeline of the three-way pipe is communicated with one outlet pipeline while the outlet pipeline of the three-way pipe is communicated with an injector, and when a piston of the injector is pulled to the predetermined scale, liquid samples in the anaerobic fermentation system are sucked into the injector under the action of the difference of the internal pressure and the external pressure of the piston. The method provided by the invention adopts the medical three-way pipe to collect the gas and liquid samples in the anaerobic fermentation process, and can be widely applied to sampling analysis of gas and liquid components in the research process of precision experiments of generating biogas through anaerobic fermentation.

The invention provides a distributed one-stop collection method and system, and the method comprises the steps: distributed collection cluster construction: adding a cluster server to a collection cluster, and adding a collection application to the cluster server; whole-network collection: enabling the cluster server to receive websites needing to be collected, perform whole-network data collection and filter list page data in the websites; analyzing: analyzing the filtered list page to obtain a list page website rule and a rule of a detail page in the list page; and collection task configuration: configuring collection applications required by incremental collection and total collection, and then starting incremental collection and total collection. A user can distribute collection resources in a user-defined mode according to collection requirements, the collection resources are automatically released after an collection task is finished, and the collection efficiency is effectivelyimproved.
