Description

Infrared lateral burner for fine chemical kiln

Technical Field

The utility model belongs to industrial kiln gas burner field relates to a meticulous chemical industry kiln infrared ray lateral burner.

Background

The production of fine chemicals produces a large amount of gaseous by-products which are environmentally friendly and some of which have a high combustion value, such as acetic acid gas (CH)₃COOH) is 2600 kcal, so many fine chemical enterprises introduce the acetic acid gas into the kiln to participate in combustion, thus on the one hand, the environmental protection treatment of the acetic acid gas is completed; on the one hand, the energy is also saved. The mixing amount of the acetic acid gas accounts for about 20 percent of the total combustion gas amount. However, the acetic acid gas has strong corrosivity, the burner is greatly damaged in the combustion process, the lateral combustion nozzle of the burner is arranged at a right angle with the combustion gas flow, the structure is thinner, the resistance of the combustion gas flow is high, and the combustion temperature of the combustion nozzle is high, so that the combustion nozzle is corroded quickly, the normal production is influenced, and the enterprise loss is large. In addition, the existing infrared lateral burner of the fine chemical engineering kiln has structural defects, so that the combustion efficiency is lower.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a corrosion-resistant, effectual fine chemical industry kiln infrared ray lateral burner of energy-conservation to solve the problem that prior art exists.

The technical scheme of the utility model as shown in figure 1, a meticulous chemical industry kiln infrared ray lateral burner, including the gas inlet tube, mix shrink tube and expansion pipe, the expansion pipe front end is the combustion nozzle, there is gas inlet and acetic acid gas access mouth gas inlet in gas inlet tube rear end, the combustion nozzle includes the annular lateral combustion spout that comprises flow distribution plate and guide plate, still include the flame stabilizing device of combustion spout rear end, the acute angle alpha that the radial and vertical direction of the annular lateral combustion spout that its characterized in that comprises flow distribution plate and guide plate formed is 10 ~ 20 jiaos, make flame and cellar for storing things wall acutangular jet combustion, the guide cone of gaining in strength is made to the guide plate rear portion. After adopting above-mentioned structure, the water conservancy diversion cone has increased the thickness and the intensity of water conservancy diversion board, has increaseed heat radiating area, has improved the corrosion resisting property of water conservancy diversion board, and the setting of water conservancy diversion cone can be with combustion gas guide to annular side direction burning spout, has reduced combustion gas's resistance. The diversion plate and the diversion plate form an acute angle alpha with the vertical direction, so that the combustion gas flows to the direction of the kiln wall to incline, the temperature of the kiln wall is effectively improved, and the thermal efficiency of the kiln is improved by about 15%. In addition, the corrosion resistance of the guide plate is enhanced, so that the mixing proportion of the acetic acid gas in the fuel gas can be increased, the highest mixing proportion can be 35% of the total combustion gas, and the consumption of the fuel gas is reduced.
