Abstract

An exhaust treatment apparatus includes a casing having an inlet port for allowing an exhaust gas to flow into the casing and an outlet port for allowing a purified exhaust gas to be discharged from the casing, an exhaust fan provided in the casing for sending the exhaust gas from the inlet port to the outlet port, and chemical filters provided in two or more stages between the exhaust fan in the casing and the outlet port.

First claim

What is claimed is:

1 . An exhaust treatment apparatus comprising:
a casing having an inlet port configured to allow an exhaust gas to flow into the casing and an outlet port configured to allow a purified exhaust gas to be discharged from the casing; an exhaust fan provided in the casing, the exhaust fan being configured to send the exhaust gas from the inlet port to the outlet port; and a chemical filter provided in at least one stage between the exhaust fan in the casing and the outlet port.

2 . The exhaust treatment apparatus according to claim 1 , wherein a pre-filter in at least one stage is provided in a preceding stage of the chemical filter, the pre-filter having a pressure loss higher than that of the chemical filter.

3 . The exhaust treatment apparatus according to claim 2 , wherein the pre-filter is arranged in an oblique direction relative to flow direction of the exhaust gas.

4 . The exhaust treatment apparatus according to claim 1 , wherein at least one first pre-filter is provided in a preceding stage of the chemical filter, the first pre-filter having a pressure loss higher than that of the chemical filter; and
a second pre-filter is provided between the chemical filter and the first pre-filter, the second pre-filter having a pressure loss higher than that of the chemical filter and lower than that of the first pre-filter.

5 . The exhaust treatment apparatus according to claim 1 , wherein the chemical filter comprises chemical filters in two or more stages, and
among the chemical filters, adjacent chemical filters are provided in different orientations.

6 . The exhaust treatment apparatus according to claim 1 , wherein the casing includes:
a first chamber having the inlet port; a second chamber having the outlet port; and a partition plate as a partition between the first chamber and the second chamber, and wherein the partition plate has a communication hole configured to communicate the first chamber with the second chamber; and the exhaust fan sends the exhaust gas from the inlet port of the first chamber to the second chamber through the communication hole.

7 . The exhaust treatment apparatus according to claim 6 , wherein the inlet port is provided at a lower position of the first chamber;
the outlet port is provided at a lower position of the second chamber; and the communication hole is provided at an upper position of the partition plate.

8 . The exhaust treatment apparatus according to claim 7 , wherein the exhaust fan is provided at an upper position of the first chamber.

9 . A container apparatus comprising a package having a container space surrounded by at least a roof, a front plate, and a side plate, and a content housed in the container space of the package,
the container apparatus further having: an intake port and an exhaust port provided in the package; a shutter mechanism configured to close the intake port and the exhaust port when an abnormality occurs in the content and thereby confine the exhaust gas; and an exhaust treatment apparatus provided in combination with the package, wherein the exhaust treatment apparatus includes: a casing having an inlet port configured to allow an exhaust gas to flow into the casing and an outlet port configured to allow a purified exhaust gas to be discharged from the casing; an exhaust fan provided in the casing, the exhaust fan being configured to send the exhaust gas from the inlet port to the outlet port; and chemical filters provided in two or more stages between the exhaust fan in the casing and the outlet port.
