TL;DR: In this article, the utility model relates to a porous diluting device of smoke particulate, including diluting exocoel (2 -41), diluting inner chamber (2 −42), and carrier gas heater (4 -4).
Abstract: The utility model relates to a porous diluting device of smoke particulate, including diluting exocoel (2 -41), diluting inner chamber (2 -42) and carrier gas heater (4 -4), seted up dilutent hole (2 -43) on diluting inner chamber (2 -42), the design of dilution hole is conical aperture, is close to the bottom surface diameter that dilutes the exocoel and is greater than the bottom surface diameter near diluting the inner chamber, the carrier gas is diluted the inner chamber by carrier gas heater (4 -4) heating for hot carrier gas back -porch dilution exocoel (2 -41) gets into through dilution hole (2 -43). The utility model discloses a change the dilutent effect of the temperature control flue gas of carrier gas, can realize that mixture temperature is adjustable. And the diluent gas gets into the transmission line through the aperture that distributes on the transmission line, and the messenger dilutes more evenly.

TL;DR: In this paper, a method for recycling high-order heat of reaction gas of a methanol-to-propylene device was proposed, and the problems that the quantity of equipment as well as the energy consumption are relatively high in the prior art are mainly solved.
Abstract: The invention relates to a method for recycling high-order heat of reaction gas of a methanol-to-propylene device. According to the method, the problems that the quantity of equipment as well as the energy consumption are relatively high in the prior art are mainly solved. According to the technical scheme, high-temperature methanol-to-propylene mixed reaction gas at an exit of a methanol-to-propylene reactor enters a methanol-to-propylene mixed reaction gas flue (1) and is subjected to gradual heat exchange with a DME reactor exit reaction gas heater (10), an ultrahigh-pressure steam generator (3), a first methanol vaporizer (2) and a second methanol vaporizer (6) which are sequentially arranged in the flue (1) to recover heat, and the low-temperature methanol-to-propylene mixed reaction gas is discharged out of the flue (1) after the heat exchange, so that the problems are well solved. The method can be applied to the methanol-to-propylene device.
