The invention relates to a combined hydrogen chloride absorption tower, which comprises a tower body, wherein the tower body consists of a primary absorption section and a secondary absorption section arranged above the primary absorption section; the primary absorption section consists of two parts, i.e. an upper barrel and a lower barrel, and the secondary absorption section consists of three parts, i.e. an upper barrel, a middle barrel and a lower barrel; an inner cavity of the lower barrel of the primary absorption section is communicated with the lower end of a perpendicular flow passage, the lower barrel is a graphite barrel, an acid outlet is formed in the bottom of the lower barrel, and a hydrogen chloride inlet is formed in the sidewall of the lower barrel. The combined hydrogen chloride absorption tower has the advantages that hydrogen chloride enters the absorption tower from the bottom of the primary absorption section, diluted hydrochloric acid enters the absorption tower from the top, and a backflow absorption mode is adopted, so that the heat exchange area is large, and the absorption rate of hydrogen chloride is increased; meanwhile, the diluted hydrochloric acid of the secondary absorption section flows into the primary absorption section directly along the perpendicular flow passage after passing through a filler layer, so that a conventional external pipe connecting mode is eliminated, and the material cost is lowered.

The invention belongs to the technical field of protein powder, and specifically relates to fat-reducing protein powder. The fat-reducing protein powder is packed into a glass bottle through a material charging device, wherein the material charging device includes a workbench, a conveying device, a material charging unit and a controller, wherein the conveying device includes rotating wheels and abelt, and the material charging unit includes a storage box, a No. 1 cylinder, a No. 2 cylinder, flexible shafts, swing plates and No. 1 cylinders. Since the fat-reducing protein powder in the storage box is packed into the glass bottle through the material charging unit, the fat-reducing protein powder in the storage box is prevented from falling directly into the glass bottle, therefore, outputof the fat-reducing protein powder is prevented when the glass bottle is not directly under a material discharge mouth, and waste, caused by contamination, of the fat-reducing protein powder is avoided through no packing of the fat-reducing protein powder into the glass bottle; and even if the fat-reducing protein powder which is not packed into the glass bottle can be eaten again, a procedure for processing the contaminated fat-reducing protein powder is needed, and the production cost of the fat-reducing protein powder is increased.

The invention provides a novel carbon tank structure. The novel carbon tank structure comprises a carbon tank main body, wherein the main body is provided with a vent communicated with the outside air. The novel carbon tank structure is characterized by also comprising a protecting cap which covers on the vent; the protecting cap is internally provided with a filtering core along the inner wall; the bottom part of the protecting cap has a convex filtering-core supporting structure; the filtering core is clamped in space between the protecting cap and the filtering-core supporting structure by the filtering-core supporting structure; a fastener which extends into the vent is convexly arranged at the central part of the protecting cap; and the protecting cap is fastened with the vent by the fastener in a clamping manner. The novel carbon tank structure provided by the invention has the advantages that the condition that the protecting cap falls due to vibration in the running process of the whole vehicle can be avoided, the water and sand particles are prevented from directly falling into the carbon tank to block the vent of the carbon tank, and the dust with large particle diameter in the air is prevented from entering the carbon tank along with the air flow to block the vent of the carbon tank.

The invention provides a flow guide anti-smashing system suitable for a double-flow surface water-cooled condenser of an intercooling unit.

The invention discloses a computer dust-proof case, which comprises the case. An air intake mechanism and an air outlet mechanism are respectively detachably installed on one opposite surface of the case. Gas enters through the air intake mechanism. The combination of the baffle plate and the baffle forms the first protection, preventing external dust or impurities from falling directly on the air intake plate, entering the chassis from the air intake hole, and forming the second protection through the cooperation of the baffle plate and various filter components. The airflow in the chassis is filtered to prevent dust from entering the chassis with the airflow. The airflow in the chassis reaches the notch, drives the shielding bar to rotate and move away from the air outlet plate, thereby opening the notch, discharging gas, and controlling the shielding bar away from The distance of the air outlet plate does not need to be manually adjusted, and when there is no air flow, the shielding strip will naturally droop to completely cover the opening of the notch, preventing dust from the external environment from entering the inside of the chassis from the notch, and further improving the dustproof effect of the chassis.
