The invention relates to a biomass gas decoking device and a comprehensive biomass utilization system. The device comprises a first decoking chamber, a second decoking chamber, a waste liquid collector, a gas inlet, a gas outlet and a first liquid drain port; first adsorption packing is arranged in the first decoking chamber, and second adsorption packing is arranged in the second decoking chamber; the gas inlet is formed below the first decoking chamber; the gas outlet is formed above the second decoking chamber; the first liquid drain port is formed in the bottom of the device; a liquid collecting port of the waste liquid collector is formed between the first decoking chamber and the second decoking chamber; the gas outlet end of the first decoking chamber is communicated with the gas inlet end of the second decoking chamber. The system is formed by connecting a carbonization furnace, a first separating unit, a collision separator, a condensing unit, the biomass gas decoking device, a draught fan, a second separating unit, a mixing gas tank, a water seal, a dryer and a gas storage cabinet in series. According to the biomass gas decoking device and the comprehensive biomass utilization system, the decoking effect is excellent, no wastewater is generated, and the equipment has no blocking risk.

A test pile comprises a hollow pile body. The lower portion of the pile body is located underground, and the pile body is located above or beside an underground pipeline. A test block pipe is installed in the pile body. A cabin door is arranged on the pile body. A wiring board is installed in the pile body. A test block is installed in the test block pipe. A reference electrode is installed in the pile body. The test block, the reference electrode and the pipeline are connected with the wiring board. The lower portion of the test pile is inserted underground, the test block is installed in the test block pipe, the reference electrode is installed in the lower end of the test pile, and therefore the lower portion of the test pile can be used as a reference pipe, and it is unnecessary to additionally install a reference pipe; installation and layout are simple, and the cost of whole pipeline cathode protection engineering is also reduced. When the reference electrode is calibrated, a working electrode for calibration can be conveyed to an underground position through the test pile, the working electrode is made to be close to the reference electrode to be calibrated as much as possible, and calibration is more accurate; the reference electrode to be calibrated can also be taken out to an overground position from the underground position along an inner cavity of the test pile, the reference electrode directly gets close to the working electrode on the ground, calibration is conducted, and therefore calibration accuracy is improved; moreover, the reference electrode and the test block can be taken out from the underground position and are convenient to replace and maintain.

A filter bag of a vacuum cleaner has a filter mounting plate that includes a generally strap-shaped securing element with pivot members on an end thereof. A housing of the vacuum cleaner defines a filter bag compartment therein and has pivot receivers into which the pivot members can be substantially vertically inserted. Then the filter mounting plate can be pivoted into a substantially horizontal installed position as the filter bag is inserted into the filter bag compartment. In the installed position, a first stop member of the filter mounting plate contacts and is stopped by a second stop member of the housing so as to prevent further pivoting and so as to properly position and hold the filter mounting plate.

The invention discloses a buried tap water pipeline leak detection device, which comprises a leak detection probe buried in a water leakage detection area and a leakage detection circuit connected with the leakage detection probe, the leakage detection probe is a humidity detection probe; the leakage detection probe includes Two wires arranged in parallel and covered with an insulating layer on the outside, and a plurality of conductive points are arranged on the two wires; the leakage detection circuit is a resistance value detection circuit that detects the resistance value between the two wires, The leakage detection device has a simple structure, convenient layout and good detection effect, without any adjustment to the structure of the pipeline to be detected. The invention also discloses a leakage detection method, comprising steps: 1. Embedding of the leakage measuring head: while burying the tap water pipeline to be detected, burying the leakage measuring head in the water leakage detection area; 2. Connecting the leakage detection circuit; 3. Leakage Detection, the leak detection method has simple steps, reasonable design and no need to change the structure of the pipeline to be tested, and has high detection accuracy.
