Title: Method for backwashing safety filter
Inventor: KONDO TAKEHIKO
IPC: B01D29/62
Filed: 1987-01-26
Abstract: PURPOSE:To reduce the expense for a pipeline for city water and also to prevent backwash from being made impossible due rust in the pipeline by intactly using permeated water of a safety filter as water for backwash. CONSTITUTION:Ordinarily, at a time for water sampling, treatment water is introduced into a safety filter 6 through an introduction path 1 and filtered and the filtrate is conducted through a conduction path 2. On the other hand, at a time for backwash, e.g. in case of backwashing a safety filter 6a of a safety filter system 4a, at least one e.g. a safety filter system 4b selected from the other safety filter system 4 is ordinarily set in water sampling state. The introduction valve 7a of the system 4a is closed and also both the conduction valve 10a and backwash valve 8a are opened and thereby the filtrate permeated through a safety filter 6b of the system 4b is introduced into the safety filter 6a through the introducing path 2a via the conduction valve 10a and thereafter it is discharged through a backwash path 3a via the backwash valve 8a.

IPC: F28F1/12
Filed: 1984-02-01
Abstract: PURPOSE:To contrive an improvement in heat transfer performance, by setting up partly large arrangement intervals of fins. CONSTITUTION:A large number of needle fins is arranged between adjoining up and down flat heat transfer tubes 1. Intervals P1-Pn among lined needle fins 2-1-2-n running along the direction (in the direction of an arrow) of an air 3 current are made to vary partially for setting up large so that the intervals are in a relation of P1=P2=P3=P5=P4. In addition to the above, although the intervals among the needle fins in the direction meeting at right angles with the direction of the air 3 current are set up evenly, the intervals can be set up large partially. With this construction, water drops to be formed around the needle fins 2-1-2-n do not form a water film even if they are developed, the water drops developed up to some extent are dropped along the fins through gravity, a heat transfer surface is exposed and favourable heat transfer properties are obtained.
