改善されている。
(In the old operating method, the concentration section A, where the largest amount of free water is separated, is heated using the residual heat after heating in the dehydration section B, so the thermal efficiency is slightly lower than in method (I). It has been improved.

(III)の如き運転法は(II)の如き方法と組合わ

When the operating method like (III) is combined with the method like (II), high temperature acts on the cake with lower moisture content, and lower temperature acts on the cake with higher moisture content, so it is a rational method with good thermal efficiency. This is a heating dehydration method.

この場合、圧搾板5,6の圧力を後方になるに従って増

In any case, sludge can be dehydrated relatively easily by squeezing force alone up to a certain water content, but once it has been dehydrated to a certain extent and reaches a low water content state, the dehydration effect becomes worse with squeezing force alone, so at such a point, When the sludge is heated, the dewatering effect is enhanced and the water content is further reduced.

従って、泥状物の温度が脱水過程で圧搾力の増加あるい

わけである。
Therefore, it is desirable that the temperature of the slurry becomes higher as the squeezing force increases or the cake water content decreases during the dehydration process.

The present invention provides an apparatus for transporting slurry by a running furnace cloth belt and compressing and dehydrating it with a pair of pressing plates each having water passage holes and having one or more stages, at least one of said pressing plates. In addition to providing an inlet and an outlet for the heating medium on one side, each of the inlet and the outlet is connected to a transfer flow path for the heating medium, so that the squeezing force and thermal action are used together, so the squeezing force is relatively small. The slurry is efficiently dehydrated, resulting in a low-moisture cake with good peeling. In addition, since heating is performed on the semi-solid slurry under squeezing power, heat conduction and thermal efficiency are improved. Generally, low-temperature heating has a dehydrating effect, and the heating temperature of this slurry is 150°C or less to promote dehydration, and within this range, denaturation of organic substances such as proteins and generation of bad odors are low. If a temperature higher than that temperature is applied, the moisture content of the cake can be significantly reduced due to denaturation of the sludge and evaporation of water, and since the heating medium passes through the press plates and rolls, there is no contamination of the heating medium. ,
It has the advantage of being able to be used in circulation, and that incinerator waste gas can be used as a heating medium, making effective use of heat, making it possible to economically produce a large amount of cake with a low moisture content continuously. This method has many practical advantages, such as good cake peeling and the ability to make the device very compact.
