A gangue foam concrete building block for realizing self heat insulation of walls relates to a self-heat-insulation foam concrete building block of light walls and consists of a high-strength gangue foam concrete shell and an ultra-low-density foam concrete core. Gangue solid wastes are utilized as main raw materials, are used for preparing the gangue foam concrete building block for realizing self heat insulation of walls, and are turned into wealth, cost of products is reduced, natural resources are saved, and the gangue foam concrete building block is favorable for environmental protection. In addition, the gangue foam concrete building block further has the advantages that strength is high, heat conduction coefficient is low, heat insulation is good, the gangue foam concrete building block is directly plastered after being built, heat insulation treatment on the inner side or outer side of a wall is not required, construction speed is greatly increased, construction completion time is shorted, and the like. Accordingly, the gangue foam concrete building block can be widely used for building single heat-insulation walls (with a self heat insulation effect) of external walls, internal and external partition walls of frame structures, rear plate walls of large wall cabinets, and fireproof, sound-insulation and heat-insulation layers of internal walls.

The invention discloses a tobacco dryer and a tobacco drying room. The tobacco dryer comprises a case shell, a compressor, a mixing condenser, an evaporator and a throttling device. The compressor, the mixing condenser, the evaporator and the throttling device are arranged in the case shell and communicated through a pipe to form a circulation system. The evaporator is arranged towards the outside of the tobacco drying room, and an evaporator heat-exchange fan is arranged on the evaporator. The mixing condenser is arranged towards the inside of the tobacco drying room, and a drying circulation heat-exchange fan is arranged on the mixing condenser. A traditional coal fuel heating type tobacco heating energy consumption mode is changed, the effects of energy conservation and emission reduction and reduction of environmental pollution can be achieved, potential production safety hazards in the traditional coal fuel heating type drying mode are avoided, precise control over the temperature and humidity in the tobacco drying room can be achieved, the influence on tobacco quality due to loss of essence during tobacco drying caused by exhaust and dehumidification is prevented, and accordingly quality of finished tobacco is guaranteed.

The invention relates to a heparin sediment and waste alcohol separation device. The heparin sediment and waste alcohol separation device comprises a desorption tank, an alcohol sedimentation tank, a waste alcohol storage tank, a gas storage tank and a vacuum pump, wherein the lower end of the desorption tank is connected with the upper end of the alcohol sedimentation tank by a pipeline; the upper end of the alcohol sedimentation tank is provided with a vacuumizing pipe and the other end of the vacuumizing pipe is connected with the upper end of the gas storage tank; the upper end of the gas storage tank is connected with the vacuum pump by a pipeline; a waste alcohol recycling pipe is arranged at the position, close to the lower end, of one side of the alcohol sedimentation tank; the waste alcohol recycling pipe is communicated to the upper end of the waste alcohol storage tank and is provided with a conveying pump; the lower end of the alcohol sedimentation tank is provided with a sediment discharging pipe; the sediment discharging pipe is provided with a discharging valve; and a sediment recycling bucket is arranged at the lower end of the sediment discharging pipe. The heparin sediment and waste alcohol separation device has the advantages that desorption liquid can be rapidly and sufficiently conveyed to the sedimentation tank and the production efficiency is improved; an alcohol and heparin sediment mixed solution can be effectively separated on the basis of omission of a power device, and an alcohol solution is recycled in time; and energy conservation and emission reduction can be realized, and the production cost can be effectively reduced.
