Abstract

A fluid purifying apparatus that purifies fluid containing organic matter has a reactor including a first transfer part that receives the fluid from outside and transfers the fluid in a vertical direction from an upper side to a lower side while heating and pressurizing the fluid and mixing the fluid with an oxidant, a second transfer part that receives the fluid that has passed through the first transfer part and transfers the fluid in the vertical direction from the lower side to the upper side, and a partition member that partitions an upper part of the reactor into the first transfer part and the second transfer part, and a solid storage part that communicates with the first transfer part and the second transfer part below the partition member and receives solid matter contained in the fluid that settles while the fluid is transferred.

First claim

What is claimed is:

1. A fluid purifying apparatus comprising:
a preheating part;
a preheating device fixed to an outer wall of the preheating part and configured to preheat a fluid to be purified;
a reactor that purifies the fluid, wherein the fluid contains organic matter, the reactor being configured to mix an oxidant with the fluid while heating and pressurizing the fluid to induce decomposition of the organic matter;
wherein the reactor comprises a first reactor portion and a second reactor portion, and the first reactor portion includes:
a first transfer part that receives the fluid from outside and transfers the fluid in a vertical direction from an upper side to a lower side while heating and pressurizing the fluid and mixing the fluid with the oxidant;
a second transfer part that receives the fluid that has passed through the first transfer part and transfers the fluid in the vertical direction from the lower side to the upper side;
a partition member that partitions at least an upper part of the first reactor portion into the first transfer part and the second transfer part; and
a solid storage part that communicates with the first transfer part and the second transfer part and is arranged below the partition member with respect to the vertical direction, the solid storage part being configured to receive solid matter contained in the fluid that settles while the fluid is transferred through the first transfer part and the second transfer part,
wherein the preheating part extends above the partition member in the vertical direction and is disposed to be preheated by the preheating device;

wherein the fluid purifying apparatus further comprises
a heater fixed to an outer wall of the second transfer part, and
a communication pipe disposed between the preheating device and the heater in the vertical direction, for communicating the second transfer part with the second reactor portion.

2. The fluid purifying apparatus as claimed in claim 1 , wherein
a catalyst for accelerating oxidative decomposition of the organic matter is arranged within at least one of the first transfer part and the second transfer part.

3. The fluid purifying apparatus as claimed in claim 1 , wherein
a catalyst for accelerating oxidative decomposition of the organic matter is arranged within the second transfer part.

4. The fluid purifying apparatus as claimed in claim 1 , wherein
the solid storage part is arranged to be detachable from a main part of the reactor including the first transfer part and the second transfer part.

5. The fluid purifying apparatus as claimed in claim 1 , wherein
an introduction pipe for introducing the fluid into the first transfer part is arranged to protrude downward in the vertical direction from an upper end wall of the first transfer part; and
a discharge port for discharging the fluid that has been transferred through the second transfer part is arranged at a position above a lower end of the introduction pipe, which is arranged within the first transfer part.

6. The fluid purifying apparatus as claimed in claim 4 , wherein
the solid storage part is arranged into a pipe structure that extends in the vertical direction and the solid storage part is connected to the main part of the reactor by a coupling.

7. The fluid purifying apparatus as claimed in claim 6 , wherein
the main part of the reactor and the solid storage part are connected via a valve part.

8. The fluid purifying apparatus as claimed in claim 7 , further comprising:
an open pipe, a storage part open valve, and a booster pump.

9. The fluid purifying apparatus as claimed in claim 1 , further comprising:
an accumulation level detection unit that detects an accumulation level of the solid matter stored within the solid storage part.

10. The fluid purifying apparatus as claimed in claim 7 , wherein
a first metal gasket is arranged between the main part of the reactor and the valve part, and a second metal gasket is arranged between the valve part and the solid storage part.
