Abstract

The utility model discloses a formaldehyde tail gas burner, including a water sealing groove, a combustion furnace and a blower. Wherein the combustion furnace is divided to a combustion chamber, a steam engine and an exhaust pipe from down to up; the steam engine includes an inlet pipe and a steam pipe; the water sealing groove is provided with a tail gas pipe, an evacuation pipe and an air inlet pipe; the evacuation pipe is provided with an evacuation valve; the air inlet pipe is provided with an inlet valve and is extended into the combustion chamber of the combustion furnace; and the blower is provided with a blast pipe which is extended into the combustion chamber of the combustion furnace. In the utility model, the tail gas generated in formaldehyde production contains combustible gas, which is fully mixed with air to be combusted, thereby not only is the pollution problem solved, but also steam is generated, and heat energy is fully utilized.

Description

A kind of formaldehyde exhaust combustion device

Technical field

The utility model relates to a kind of exhaust gas processing device of Formaldehyde Production, particularly a kind of formaldehyde exhaust combustion device.

Background technology

In the industrial formol production process; The tail gas that produces contains 18-21% hydrogen; 0.1% formaldehyde gas and 0.01% methyl alcohol and a small amount of methane gas and 0.4% CO gas, 3.6 ~ 4.0% carbon dioxide; All the other are 74% nitrogen, and industrial formol tail gas directly discharging can cause environmental pollution, and it is healthy to influence personnel.Simultaneously, imflammable gas directly discharges, and can cause potential safety hazard.

The utility model content

The purpose of the utility model is that a kind of formaldehyde exhaust combustion device will be provided.

In order to achieve the above object; The technical scheme of the utility model is: a kind of formaldehyde exhaust combustion device; This device comprises water sealed tank, combustion furnace, air blast, and wherein: said combustion furnace is divided into combustion chamber, steam engine, blast pipe from the bottom to top, and this steam engine comprises water inlet pipe and steam pipe; Offgas duct, evacuated tube, air inlet pipe are set on the said water sealed tank, on this evacuated tube exhaust-valve are set, intake valve is set on this air inlet pipe and stretches in the combustion chamber of combustion furnace; Be provided with on the said air blast in the combustion chamber that a blast pipe stretches to combustion furnace.

The utility model utilizes the tail gas of Formaldehyde Production to contain imflammable gas and the abundant mixed combustion of air, and promptly contaminated solution has to produce steam, and heat energy makes full use of.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

As shown in Figure 1, a kind of formaldehyde exhaust combustion device, this device comprises water sealed tank 2, combustion furnace, air blast 6, and said combustion furnace is divided into combustion chamber 5, steam engine 8, blast pipe 10 from the bottom to top, and this steam engine 8 comprises water inlet pipe 7 and steam pipe 9; On the said water sealed tank 2 offgas duct 1, evacuated tube, air inlet pipe are set, exhaust-valve 3 is set on this evacuated tube, intake valve 4 is set on this air inlet pipe and stretches in the combustion chamber 5 of combustion furnace; Be provided with on the said air blast 6 in the combustion chamber 5 that a blast pipe stretches to combustion furnace.

The tail gas of Formaldehyde Production gets into water sealed tank 2 through offgas duct, slowly closes earlier exhaust-valve 3 before the tail gas igniting, slowly opens intake valve 4 simultaneously; Tail gas gets in the combustion chamber 5, and air blast 6 blasts air in the combustion chamber 5, and tail gas fully mixes with air; The flow of air leans on air blast 6 rotating speeds to regulate, and guarantees in the explosion limit scope of tail gas safety, to light a fire, in combustion chamber 5 internal combustion; Temperature 400-600 ℃, steam engine 8 is heated, demineralized water gets into steam engine 8 from water inlet pipe 7; After thermal conversion is steam, heat energy outwards is provided from steam pipe 9, tail gas through burn up to standard after, discharge from blast pipe 10.

All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into the protection domain of the utility model.

Claims

1. a formaldehyde exhaust combustion device is characterized in that this device comprises water sealed tank, combustion furnace, air blast, wherein:

Said combustion furnace is divided into combustion chamber, steam engine, blast pipe from the bottom to top, and this steam engine comprises water inlet pipe and steam pipe;

Offgas duct, evacuated tube, air inlet pipe are set on the said water sealed tank, on this evacuated tube exhaust-valve are set, intake valve is set on this air inlet pipe and stretches in the combustion chamber of combustion furnace;

Be provided with on the said air blast in the combustion chamber that a blast pipe stretches to combustion furnace.
