Description

Defoaming device for overflow pipe of desulfurizing tower

Technical Field

The utility model relates to an industry defoaming field, concretely relates to desulfurizing tower overflow pipe fire fighting equipment.

Background

Slurry foaming overflow of the desulfurization tower not only pollutes the field environment, but also can cause serious corrosion to equipment at the front and the rear of the desulfurization tower, such as a flue, a chimney and the like, so that basic equipment is damaged. Foam overflow of a desulfurizing tower has become a significant problem in industry circles. At present, a limestone-gypsum wet flue gas desulfurization process is mostly adopted in a desulfurization tower, but the foam overflow frequency is too much in the production process, so that the serious influence is brought to production operation and site environment. The phenomenon of overflow is often generated due to the problem of foam in the desulfurization process of a power plant, so that great negative effects are caused.

The common defoaming methods in the current production include two methods: firstly the defroster is followed the eminence and is spouted water, has the scouring force, can eliminate the partial foam of liquid level, alleviates the foaming degree of absorption tower, nevertheless if absorption tower liquid level itself is too high, just can't open the defroster and clear away the foam. If the foam in the desulfurizing tower and the foam overflowing to the lower part of the equipment are not removed in time, the foam is accumulated more and more, and the environment and the production safety of a site are seriously influenced. And the desulfurization defoaming agent added into the power plant is an effective means capable of solving the problem of desulfurization foam of the power plant at present, and the desulfurization defoaming agent for the power plant has the characteristics of good stability, strong dispersion performance and permeability, small addition amount, high safety and the like when being used for treating the desulfurization foam of the power plant. However, the use of defoamers is expensive, and the cost of the defoamers required for a quarter is usually higher than the equipment cost itself, resulting in a large increase in the overall production cost.
