Problems solved by technology
As a result, the smoke sensor has a problem that it takes time to maintain it.
[0007] On the other hand, although a dust collector using a temperature sensor and a smoke sensor is also known (Patent Document 1), even if both sensors are mounted, they cannot completely compensate for each other's defects, so it is not an effective means.

Embodiment
[0081] Next, a fire experiment performed as an example of the present invention will be described.
[0082] Figure 8 is the dust collecting device 50 used in the experiment and figure 1 Same attached picture. For the dust collector 50, its basic structure is the same as that of the dust collector 40 of the second embodiment. The difference between the dust collector 50 and the dust collector 40 is that the dust detection sensor is installed on the downstream side before the blower outlet 2a. On the basis of 42, temperature sensors 52, 54 are respectively installed at the inlet of the blower and the outlet of the blower 2a.

The purpose of the invention is to provide a dust collection device and a method for detecting fire in the dust collection device, whereby fire can be detected promptly and reliably in the event that a fire has ignited inside the device. A dust collection device (1) that separates dust from dust-containing air, by using a blower to suction in dust-containing air that includes dust, and by causing the dust-containing air to pass through a filter. The dust collection device is characterized by comprising: a dust-containing air chamber (10) to which the suctioned dust-containing air is guided; a clean air chamber (16) separated from the dust-containing air chamber by a separation means including the filter (4), and to which cleaned air filtered by the filter is guided; and a dust detection sensor (24) arranged on the clean air chamber side.
Description
technical field [0001] The present invention relates to a dust collecting device and a fire detection method of the dust collecting device, in particular, to a dust collecting device and a fire detection method of the dust collecting device capable of rapidly and reliably detecting the fire when a fire occurs inside the dust collecting device Detection method. Background technique [0002] A dry dust collector used for dust collection in a dry environment may cause a fire inside if dust containing hot substances such as sparks is inhaled. In order to prevent such a fire, the following measures are taken: installing a device to shake off sparks, etc. at the front of the dust collector, or installing a sensor to detect sparks, etc., and stopping the dust collector when sparks are detected, etc. . [0003] However, even if the above-mentioned measures are taken, it is difficult to completely prevent a fire in the dust collector, and therefore it is desired to be able to quick...
