Abstract
An alkali liquor desulfurization system comprises an alkali liquor tank and a desulfurization tower. An alkali liquor feed pipe is connected to the alkali liquor tank which is an alkali liquor circulating tank, a circulating pump is arranged between the alkali liquor tank and the desulfurization tower, alkali liquor in the alkali liquor tank is delivered to the top of the desulfurization tower through the circulating pump, a liquor return pipe is arranged on the lower portion of a liquor feed pipe on the desulfurization system and communicated with the alkali liquor tank, the liquor feed pipe of the desulfurization tower is provided with a bypass pipe. Since the alkali liquor tank is modified into the alkali liquor circulating tank, an alkali liquor metering pump is omitted, investment of equipment for an alkali washing stage is saved, consumption of alkali liquor is reduced, replacement frequency of dry desulfurizer is reduced, and cost is saved.
Description
Technical field
The utility model relates to a kind of oxygen-eliminating device.
Background technology
Alkali lye generally is between alkali groove and desulfurizing tower, connect alkali lye measuring pump 8 and NaOH solution circulating pump 4 in sulfur removal technology, because that alkali lye section measuring pump is prone to stop up is malfunctioning, can't monitor liquid level, and alkali lye consumption is big, and dried desulfurizing agent is changed frequent, has strengthened cost.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of alkali lye desulphurization system is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of alkali lye desulphurization system comprises alkali groove and desulfurizing tower, and alkali inlet tube is connected in the alkali groove; Said lye tank (vat) is the alkali lye circulating slot; Circulating pump is arranged between alkali groove and the desulfurizing tower, and circulating pump is transported to the top of desulfurizing tower with the alkali lye in the alkali groove, and the bottom of feed tube is provided with liquid back pipe on the desulfurizing tower; Liquid back pipe and alkali groove UNICOM, the desulfurizing tower feed tube is provided with bypass pipe.
Adopt technique scheme, the utility model has following advantage: through lye tank (vat) being changed into the alkali lye circulating slot, cancel the alkali lye measuring pump, the input of having saved alkali cleaning section equipment has reduced the consumption of alkali lye, has reduced the replacing frequency of dried desulfurizing agent, provides cost savings.
Description of drawings
Fig. 1 is that traditional alkali lye takes off structural representation.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
A kind of alkali lye desulphurization system as shown in Figure 2 comprises alkali groove 6 and desulfurizing tower 1, and alkali inlet tube 7 is connected in the alkali groove 6; Said alkali groove 6 is alkali lye circulating slots; Circulating pump 4 is arranged between alkali groove 6 and the desulfurizing tower 1, and circulating pump is transported to the top of desulfurizing tower 1 with the alkali lye in the alkali groove 6, and the bottom of feed tube 2 is provided with liquid back pipe 5 on the desulfurizing tower 1; Liquid back pipe 5 and alkali groove 6 UNICOMs, desulfurizing tower feed tube 2 is provided with bypass pipe 3.
