Abstract:
Integrated systems and processes are provided for drying and milling sludge and other natural waste using waste heat extracted from reheated gas through an air-air heat exchanger process. In one example, the sludge or natural waste may be dried into a powder using high-temperature gas to absorb moisture from the sludge, causing the high-temperature gas to become an at least partially saturated gas. The at least partially saturated gas may pass through a separator- scrubber cycle before a first portion is heated in an air-heater and then used to heat a second portion of the at least partially saturated gas in an air-air heat exchanger. The heat for the air-heater may be provided by a burner operable to burn the dried powder obtained from the sludge. The heated second portion of gas may be used to dry and mill the sludge and other natural waste.
Abstract:
The inventive concept relates to a sludge drying apparatus, and more particularly to a sludge drying apparatus that may improve an efficiency of drying sludge that is sewage deposit residues and simplify a drying process.
Abstract:
In one aspect, a waste disposal for processing waste may generally include a housing and a motor disposed within the housing. The housing may define an inner sidewall surface extending around an inner perimeter of the housing and a discharge outlet. The motor may include a stator and a rotor at least partially surrounding the stator. The rotor may include a sidewall defining an outer surface. The motor may be disposed within the housing such that an annular gap is defined between the inner sidewall surface of the housing and the outer surface of the sidewall. When the rotor is rotated relative to the stator, water may be drawn through the annular gap towards the discharge outlet.

Abstract:
A heated ultrasonic treating device (6) comprising a sump (13) through which suspended matter-containing liquid passes, a temperature-controllable heater (14) disposes in the sump (13), and a ultrasonic vibrator (15) disposed in the sump (13). The heated ultrasonic treating device (6) uses the ultrasonic vibrator (15) to apply ultrasonic waves while heating organic drain passing the sump (13) with the heater (14), thereby pulverizing suspended matters and reducing the amount of SS. In addition, a treating column, where pulverized suspended matter-containing liquid is aerobically treated by aerobic microorganisms, is prevented from efficiency lowering due to clogging.
Abstract:
A process for the comminution and dehydration of municipal sludge waste by feeding the municipal sludge waste into a cyclonic, dehydrating comminuter facilitates the further processing of the comminuted and dehydrated sludge material discharged from the comminuter. Both the comminuted and dehydrated sludge material and the air flow discharged from the cyclonic comminuter are sterilized to remove pathogens therefrom. The rate at which the municipal sludge material is fed into the cyclonic comminuter is directly related to the moisture content of the comminuted and dehydrated material discharged from the material discharge opening of the comminuter. Preferably, the moisture content of the discharged material is in the range of 25% to 35% to facilitate the sterilization of the discharged material. An alternative process can be used, however, to dry the discharged comminuted and dehydrated municipal sludge waste material to about 10%, such as by passing the material discharged from the first cyclonic dehydrating comminuter into a second cyclonic dehydrating comminuter until the finally discharged material has a powdery consistency.
Abstract:
A kitchen faucet with a garbage disposer includes a faucet unit, the garbage disposer, and a sensing unit. The faucet unit includes a water outlet passage unit, and the water outlet passage unit is disposed with a first control valve configured to control an opening and a closing of the water outlet passage unit. The garbage disposer is located under a water outlet of the water outlet passage unit of the faucet unit. The sensing unit is disposed on the faucet unit and is configured to generate a normal water outlet instruction and a garbage disposal instruction respectively according to a long sensing distance and a short sensing distance. The first control valve is configured to be opened and closed through the normal water outlet instruction, and the first control valve and the garbage disposer are respectively configured to be opened and closed through the garbage disposal instruction.
Abstract:
A cutting assembly and a grinder pump including the cutting assembly are disclosed. The cutting assembly includes a cutting plate that has a plurality of cutting ports with cutting edges that are distributed over a range of radial locations of the plate. The cutting edges of the cutting ports define a series of cutting regions of the cutting blades of a rotary cutter that operate in a shearing action with the cutter plate. The cutting action by the blades of the rotary cutter is distributed over nearly the entire lengths of the cutting edges of the cutting blades, thereby distributing the wear on the cutting blades evenly, and extending cutting assembly life.
Abstract:
The invention concerns a vortex machine modified to intensify the vortex in the machine by installing inlet fans in addition to the main fan and modifying the configuration of the machine. Additional intensification of the vortex is achieved by introducing microwaves into the vortex machine. The vortex machine has a vortex tube, an inlet tube to the vortex tube at the inlet end, a feed inlet to the vortex tube between the inlet end and an outlet end and a fan rotor at the outlet en to draw air in a vortex through the vortex tube. An inlet fan in the inlet tube adapted to force air into the vortex tube. These modifications and additions achieve commercially viable capacities of the vortex machine in drying, grinding and process applications.
