TL;DR: In this paper, a spray-drying method for large volumes of detergent slurry in a spraydrying tower is described, which comprises spraying at least a portion of the slurry, cocurrently with air having a specified temperature and velocity range, through uniformly spaced atomizing nozzles into a cylindrically shaped drying zone.
Abstract: A method is provided for spray-drying large volumes of a detergent slurry in a spray-drying tower which comprises spraying at least a portion of the slurry, cocurrently with air having a specified temperature and velocity range, through uniformly spaced atomizing nozzles into a cylindrically shaped drying zone. Any remaining balance of the slurry is sprayed countercurrently into the drying zone at higher levels in the spray tower. Apparatus is provided for practicing this process. Granular detergent compositions having improved physical properties are also disclosed.

TL;DR: In this paper, an incinerator and post-treatment equipment consisting of a heat exchanger, a water tank, a bag-type dust remover, an active carbon adsorption box, a spray tower, water fog separator, an induced draft fan and a chimney are presented.
Abstract: The utility model relates to remains and offering incineration and post-treatment equipment, which comprises an incinerator and post-treatment equipment. The incinerator consists of an incinerator body, a blower and an air preheater. The post-treatment equipment consists of a heat exchanger, a water tank, a bag-type dust remover, an active carbon adsorption box, a spray tower, a water fog separator, an induced draft fan and a chimney. The inside of the incinerator body is provided with main and auxiliary combustion chambers. The lateral surface of the main combustion chamber is provided with a main combustor and a soot door. The lateral surface of the auxiliary combustion chamber is provided with an auxiliary combustor. An outlet of the heat exchanger is communicated with an inlet of the bag-type dust remover through a butterfly valve. An outlet of the bag-type dust remover is communicated with an inlet of the active carbon adsorption box. An outlet of the active carbon adsorption box is communicated with the chimney. The outlet of the heat exchanger is also communicated with an inlet of the spray tower through a butterfly valve. An outlet of the spray tower is communicated with an inlet of the water fog separator. An outlet of the water fog separator is communicated with the chimney. The equipment is dedicated for processing remains and offerings, has low fuel consumption and good effect of purifying fuel gas and solves the difficult problem of burning the remains and offerings outdoors to cause environment pollution.
