A spray type air source absorption heat pump belongs to the technical field of heat supply. The spray type air source absorption heat pump includes a generator, an absorber, a condenser, a brine regeneration device, a spray tower, a solution heat exchanger, a solution pump and a throttle valve; the present invention adopts the existing centralized heating system Or directly burn fuel to drive an absorption heat pump, and extract low-grade heat energy from the air through a spray evaporator, which improves the primary energy efficiency of heating and reduces pollutant emissions. Compared with traditional air source heat pumps, there is no risk of frost in winter, which ensures the reliability of heating and reduces the area of ​​air-cooled heat exchangers. Using self-exhaust smoke or absorption heat pump refrigeration method can not only realize continuous regeneration of brine, reduce the amount of brine, but also greatly reduce the energy consumption of brine regeneration. The invention has obvious energy-saving and emission-reducing effects for heating supply and preparation of domestic hot water.

The invention discloses a diesel engine exhaust purification treatment device and method, comprising a catalytic conversion section housing, a catalytic oxidant carrier, a purification and muffler section housing, a particle filter core, a resonance cavity, a perforated intake pipe, an exhaust collection pipe, and an ECU The control system, inlet and outlet pressure sensors, and fuel injectors can integrate the catalytic conversion of exhaust gas, particle capture and noise reduction functions into one, and the radial flow filter element is used to achieve particle capture, which is beneficial to reduce filter resistance; Under normal working conditions of the diesel engine, through the structural combination of catalytic oxidation and particulate capture, particulate capture and regeneration are carried out simultaneously to achieve continuous regeneration; under long-term low-load operating conditions, the fuel injection auxiliary system is activated to still ensure particulate capture and regeneration. Normal operation of regeneration function. The design of perforated intake pipe, resonant cavity, and porous ceramic noise reduction function can effectively eliminate low and intermediate frequency noise. The device has the advantages of compact structure, high particulate capture efficiency, safe and reliable regeneration process, etc.

The invention relates to a method for producing propylene from methanol or dimethyl ether, and mainly solves the problems that a catalyst is easily inactivated due to short reaction residence time and the reaction conditions are frequently fluctuated and the operation is unstable caused by frequent switch and reproduction in the prior art. The method for producing the propylene from the methanol or the dimethyl ether comprises the following steps of: a) making oxygen-containing compounds and a diluent enter a fluid bed reactor from the bottom; b) performing contact reaction on the raw materials and a ZSM-5 molecular sieve catalyst at the temperature of between 400 and 550 DEG C under the pressure of between 0.02 and 0.5 MPa; c) separating gas-phase material flow out of the top of the fluid bed reactor to obtain the propylene; d) extracting the reaction heat by using a heat exchanger; e) controlling the inactivated catalyst with a sliding valve and feeding the catalyst into a regenerator through a catalyst spending inclined tube, reacting the inactivated catalyst with air at the temperature of between 480 and 700 DEG C to burn off carbon deposit, and exhausting waste gas; and f) controlling the regenerated catalyst by using the sliding valve and feeding the regenerated catalyst to the upper part of the fluid bed reactor for circulation through a catalyst regenerating inclined tube. The technical scheme of the invention better solves the problems, and can be applied to the industrial production of the propylene.

The invention provides a method for preparing a visible light micro-nano reactor membrane for the selective removal of ammonia nitrogen. The amide is used as the main raw material, and the obtained mixed material solution is coated on a flat plate, and after the dimethylacetamide is transferred in water, it is taken out and dried to obtain a visible light micro-nano reactor film.
