Abstract

PURPOSE:To hold a fiber body effectively and reliably, by a method wherein, in a burner which performs combustion through catalyst reaction of platinum, paradium, etc., a number of projections are formed on the both sides of a porous plate which holds a heat insulating material of a fiber body and uniformizes the flow of gas. CONSTITUTION:Gas flowing through a gas inlet 1 is burnt at a heating burner 8 and a catalyst burner 9. A porous plate 11 for uniformizing the flow of gas is made of, for example, a rolled lath and is formed with a number of projections on both sides thereof. This causes a heat insulating material 10 to increase adhesion properties among the catalyst burner 9, a wire net 13, and the porous plate 11, and enables the heat insulating material to be secured thereto without using other means.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a scum combustion device, in which a heat-resistant mat is supported with a noble metal having a catalyst such as platinum or palladium, and the burner that burns combustion gas within the mat is held and warmed. The purpose is to effectively and reliably hold a cotton-like fibrous body that also serves as a fiber body.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is a gas inlet, 2 is an operation knob for igniting the heating burner 8 and opening the safety valve 3, 3 is a safety valve for the main gas passage, 4 is a gas pressure regulator, and 5 is for regulating the gas flow rate of the catalytic burner 9. The orifice 6 is a solenoid valve in the heating burner gas passage, and is closed by time control. (not shown) 7 is an orifice for regulating the gas flow rate for the heating burner, 8 is a heating burner for activating the catalytic burner 9, 9 is the catalytic burner, 10 is a heat insulating material, 11 is a heat insulating material 10, and a perforated plate with unevenness on the front and back to make the gas flow uniform; 12 is a catalyst burner 9;
, a burner box that fixes the porous material 11 and has a waste passage section; 13 is a wire mesh for protecting the catalytic burner 9; 14 is a wire mesh 1;
This is the burner holder for fixing No. 3.

FIGS. 3a and 3b show the perforated plate (lath mesh) 11, and FIGS. 4a and 4b show the perforated plate 11 before and after processing.

The operating state will be explained below.

The gas from the gas supply 1 is combusted by the heating burner 8 and the catalytic burner 9 by operating the operating knob 2. The heating burner 8 is automatically extinguished when the catalytic burner 9 is sufficiently activated and the electromotive force of a thermocouple (not shown) provided in the catalytic burner 9 is sufficient to hold the safety valve 3. It is configured. After the heating burner 8 is extinguished, the safety valve 3 of the catalytic burner 9 is stably maintained by the thermoelectromotive force generated by the thermocouple, and the catalytic burner 9 reaches steady operation.

As described above, according to the present invention, the following effects can be obtained.

1 By providing unevenness on the front and back of the perforated plate, the heat insulating material in contact with the perforated plate increases adhesion between the catalytic burner, the entire screen, and the perforated plate, and the heat insulating material can be easily bonded to the perforated plate without using other means. Can be fixed.

2. The perforated plate is made by rolling a lath mesh, and the uneven effect on the front and back of the perforated plate can be obtained without using any special method.

3. Since the lath net is rolled to a certain thickness, the air permeability is high, and the section modulus is also increased, so the strength is greater than that of a flat plate with the same air permeability.
