摘要:
An agitating impeller includes an agitation shaft and a blade section including a plurality of blade-forming sections mounted to the agitation shaft. The blade-forming sections are each formed of a planar member. An outer end portion of each of the blade-forming sections is bent backward with respect to the direction of rotation of the agitating impeller. A lower end portion of each of the blade-forming sections is formed to conform to the shape of a bottom wall of an agitating vessel in which the agitating impeller is provided. All angular portions of the individual blade-forming sections are chamfered, and agitation shaft and the blade section are glass-lined.

Disclosed is a method for continuously treating an organic waste water capable of simplifying a process step, avoiding redundant solubilizing reaction to reduce the volume of a solubilizing vessel, and performing solubilizing treatment well. In the method for continuously treating an organic waste water containing organic solids, solubilizing treatment for the organic sludge is carried out by heat and under the condition that a sludge solubilization enzyme is produced and secreted from a microorganism to promote the solubilization thereby, and solubilizing treatment time is determined based on a hydraulic residence time of a treated solution in a solubilizing treatment device.
摘要:
A batch type furnace includes a furnace body (1), a floor (2) being removably attachable to the furnace body (1) for forming a furnace chamber, and radiant tubes (3a, 3b, 3c) being substantially and uniformly arranged in the furnace body (1) and the floor (2). The radiant tubes (3a, 3b, 3c) are controllable to a predetermined temperature independently of each other. The radiant tubes (3a, 3b, 3c) are made of an alloy having a heat resistance of such a degree as to be tolerable against quick heating and cooling.

There is provided a method of repairing a damaged portion in the glass layer of glass-lined steel equipment wherein, as a first step, a first repair medium is applied to the damaged portion, solidified and adhered chemically to the steel by a sol-gel process, with the application of heat. In a second step, a second repair medium is applied on to the first layer, which second layer includes an inorganic filler and is solidified by a sol-gel process, with the application of heat. In a third step, there is applied on to the second repairing layer a liquid impregnated agent which penetrates into any voids present in the second layer and is solidified by a sol-gel process, with the application of heat.
摘要:
To achieve a simple configuration of cooling mechanism of an apparatus for producing hydrogen and oxygen and make it possible to freely select the type of heat exchanger without any restrictions so as to improve the cooling efficiency of the heat exchanger. A heat exchanger 7 for cooling deionized water in a deionized water tank 1 which contains an electrolytic cell 2 is installed outside the tank 1, an inlet 7a of the heat exchanger 7 is connected up with a deionized water flow outlet 10 that is below the level of the deionized water in the tank 1 by a pipe 9a, and an outlet 7b of the heat exchanger 7 is connected up with a deionized water flow inlet 11 that is beneath the above-mentioned deionized water flow outlet 10 in the tank 1 by a pipe 9b.
