The utility model belongs to the waste heat recovery technical field, concretely relates to a waste heat recovery equipment, including heat recovery channel, the evaporimeter of setting in the air outlet of heat recovery channel and the water tank of setting in the inboard of evaporimeter, the included angle of the side wall surface opposite water tank and evaporimeter is acute angle, the horizontal cross section of water tank is trapeziform, the utility model discloses the included angle of the side wall surface opposite water tank and evaporimeter is acute angle, so that the side of water tank and evaporimeter have certain angle of inclusion, and the hot air plays a guiding effect, and increases heat recovery efficiency, trapeziform water tank design, cleverly utilize the trapeziform gap of one end of evaporimeter contacted, and the sufficient clearance is left, and forms a half horn mouth smooth air duct, and the air inlet guiding effect is enhanced.

The application discloses a preparation method of a quaternary ammonium and sulfonated polyether sulfone ultrafiltration membrane, and the preparation method comprises the following steps: 1) sulfonating chloromethylated polyether sulfone by using chlorosulfonic acid as a sulfonating reagent to prepare sulfonated polyether sulfone; 2) preparing sulfonated and chloromethylated polyether sulfone by using 1,4-dichloromethoxy butane as a chloromethylating reagent and concentrated sulfuric acid as a solvent; 3) dissolving the sulfonated and chloromethylated polyether sulfone and a pore-forming agent in a solvent, scraping a film after preparing a casting solution; and 4) immersing the finished membrane in a trimethylamine solution by using trimethylamine as a quaternary ammonium reagent to obtain the quaternary ammonium and sulfonated polyether sulfone ultrafiltration membrane. The prepared ultrafiltration membrane has the advantages of high flux and anti-pollution due to the introduction of quaternary ammonium groups and sulfonated groups.
