Description
Technical Field
The utility model belongs to the technical field of chemical production equipment, and particularly relates to a tail gas incineration device of a formaldehyde solution production line.
Background
The formaldehyde tail gas generated in the formaldehyde solution production process needs to be subjected to incineration treatment. The existing incineration equipment is mainly a formaldehyde tail gas incinerator, for example, the application number is CN202121772652.9, and discloses a formaldehyde tail gas incinerator, and in order to improve the temperature of air entering a combustor, an energy saver is additionally arranged on a smoke pipe of the incinerator, an air preheater and a draught fan are additionally arranged, and the air is conveyed after the temperature is raised by a blower. Although the problem of air preheating is solved, the energy-saving device, the air preheater and the induced draft fan are added, on one hand, the equipment cost, the maintenance cost and the operation cost are increased, on the other hand, when the energy-saving device or the air preheater breaks down and maintains, the preheating of air is affected, and the preheating effect of the energy-saving device and the air preheater is poor.
Disclosure of Invention
In order to solve the technical problems, the utility model provides the tail gas incineration device of the formaldehyde solution production line, which has a simple structure and low cost, and the device can realize air preheating only through the sleeve sleeved on the smoke tube. The air preheating device has the advantages of simple structure, reduced manufacturing cost and production cost, and convenient maintenance.
The utility model adopts the technical scheme that: the tail gas incinerator comprises a sleeve seat, air filtering cotton, a sleeve, a heat preservation layer, an air inlet pipe, an induced draft fan and an air outlet pipe; the sleeve is sleeved on the smoke tube of the tail gas incinerator, the sleeve seat is sleeved at the bottom of the sleeve, ventilation holes are formed in the bottom of the sleeve and the sleeve seat, air filter cotton is filled in annular cavities of the sleeve and the sleeve seat, and a heat preservation layer is arranged outside the sleeve above the sleeve seat; an air inlet of the induced draft fan is communicated with the top end of the sleeve through an air inlet pipe, and an air outlet of the induced draft fan is communicated with a burner of the tail gas incinerator through an air outlet pipe.
Further, a rain cover is welded on the sleeve above the sleeve seat.
Further, a gap between the convex edge at the top end of the sleeve and the smoke tube is filled with high-temperature-resistant asbestos.
Further, the heat preservation layer is high temperature resistant asbestos or glass wool.
Further, asbestos or glass wool heat preservation layers are wrapped outside the air inlet pipe and the air outlet pipe.
Further, the sleeve seat is 15 cm-25 cm in height.
Further, the sleeve seat is 20 cm in height.
The utility model has the beneficial effects that: the tail gas incineration device of the formaldehyde solution production line is simple in structure and low in cost, and air preheating is achieved only through the sleeve sleeved on the smoke tube. The air preheating device has the advantages of simple structure, reduced manufacturing cost and production cost, and convenient maintenance.

Detailed Description
Examples
Referring to fig. 1-7, a tail gas incinerator of a formaldehyde solution production line comprises a tail gas incinerator 1, and further comprises a sleeve seat 2, air filtering cotton 3, a sleeve 4, a heat preservation layer 5, an air inlet pipe 6, an induced draft fan 7 and an air outlet pipe 8; the sleeve is sleeved on the smoke tube of the tail gas incinerator, the sleeve seat is sleeved at the bottom of the sleeve, the bottom of the sleeve and the sleeve seat are provided with ventilation holes 9, the air filter cotton is filled in the annular cavities of the sleeve and the sleeve seat, and an insulating layer is arranged outside the sleeve above the sleeve seat; an air inlet of the induced draft fan is communicated with the top end of the sleeve through an air inlet pipe, and an air outlet of the induced draft fan is communicated with a burner of the tail gas incinerator through an air outlet pipe; the gap between the convex edge at the top end of the sleeve and the smoke tube is filled with high-temperature-resistant asbestos; the heat-insulating layer is high-temperature-resistant asbestos or glass wool; asbestos or glass wool heat preservation layers are wrapped outside the air inlet pipe and the air outlet pipe; the height of the sleeve seat is 20 cm.
When the formaldehyde tail gas is burnt, air is filtered by air filtering cotton through the air holes on the sleeve seat of the sleeve, and then enters the smoke tube and the annular cavity of the sleeve for preheating through the air holes at the bottom of the sleeve. The waste heat of the smoke tube is utilized to preheat air, and the preheated air is conveyed into the burner by the induced draft fan to provide combustion-supporting oxygen for the combustion of formaldehyde tail gas. The heat loss of the heat can be reduced by the heat insulation layers outside the smoke pipe, the air inlet pipe and the air outlet pipe, and the waste heat effect of the air is improved. When the air filter cotton needs to be replaced, the sleeve seat is lifted up, and then the filter cotton is filled in the sleeve seat and the annular cavity at the bottom of the sleeve. The air preheating is realized only through the sleeve sleeved on the smoke tube. The air preheating device has the advantages of simple structure, reduced manufacturing cost and production cost, and convenient maintenance.
Examples
Referring to fig. 8, in the first embodiment, a rain cover 10 is welded to a sleeve above a sleeve seat to prevent a filter quilt from being completely wetted during raining.
