Coal gas desulfurization is important environmental protection project, and vacuum carbonate desulphurization is mainly by desulfurizing tower, Analytic Tower, vacuum pump etc. Main equipment is constituted.Desulfurizing tower is divided into two sections section, and wherein blocking easily occurs in epimere, causes SR to become big asking Topic.In desulfurization segment pipe occur blocking time, conventional method is to be disabled by epimere, then carry out steam clear or dismounting segmentation The most clear.Such method exists that the clear time is long, and effect is undesirable, affects the problems such as the stability that desulfurization produces.

Summary of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide the clear device of segment pipe in a kind of desulfurization, In the case of desulfurization epimere does not stops production, it is achieved desulfurization epimere Trunk Line clear, shorten the clear time, improve clear effect.

For achieving the above object, this utility model is achieved through the following technical solutions:

The clear device of segment pipe in a kind of desulfurization, including ammonia still, desulfurizing tower, blender, 5% alkali groove, flow control valve A, controlling valve b, controlling valve c, distilled ammonia wastewater send pump outside, and desulfurizing tower is connected with ammonia still through 5% alkali groove, 5% alkali groove and ammonia still Between by send outside pipeline connect；Ammonia still is connected with desulfurizing tower epimere through flow control valve a, blender successively, ammonia still with Connecting between flow control valve a and have distilled ammonia wastewater to send pump outside, flow control valve a two ends connect has bypass line, in bypass line Connect and have controlling valve b and controlling valve c；Also include valve d, valve g, valve f, valve h, by-pass line one, by-pass line two, other The bypass line threaded a pipe between an one end with flow control valve a and controlling valve c is connected, and the other end is connected with sending pipeline outside；Other The bypass line threaded a pipe between two one end with controlling valve b and controlling valve c is connected, and the other end is connected with sending pipeline outside；Bypass pipe The pipeline of sending outside being connected between road one with by-pass line two is provided with valve f, and by-pass line one connects valve g, bypass pipe Connect on road two and have valve d；Being connected between 5% alkali groove and valve f has alkali groove to send pump outside.

Compared with prior art, the beneficial effects of the utility model are:

Improve clear speed, improve clear effect, by using this device, in the situation that desulfurization epimere does not stops production Under, it is achieved desulfurization epimere Trunk Line clear, and clear simple operation, the clear time shortens, shortened to 1 by original 4 days My god.By by-pass line valve d, the switch of valve g, it is achieved clean selection and the selection of pipeline of medium；Use steam, medicine Distilled ammonia wastewater pipeline before flow control valve a is carried out clear by agent or high-temperature residual heat water, clear blowdown at ammonia still；On desulfurizing tower Section sprinkling system then utilizes the alkali groove connecting 5% alkali groove to send pump outside as power, carries out interior circulation, it is ensured that desulfurization produces stable.
