Abstract
A preheater on an ammonium sulphate section comprises a preheater body, wherein a gas inlet pipe is connected to the lower part of the preheater body; a gas exhaust pipe is connected to the upper part of the preheater body; a blow-off pipe is arranged at the bottom of the preheater body; a flange is arranged at the upper end of the preheater; an end cover is assembled with the preheater body; and a large-discharge capacity valve is arranged on the blow-off pipe. Through the adoption of the technical scheme, the preheater has the advantages that as the flange is mounted on the preheater body, the end cover at the upper end of the preheater body can be assembled on the preheater body through the flange. When cleaning is required, all that is needed is to dismount the end cover at the upper end of the preheater body, so as to clean the preheater conveniently without hoisting and dismounting the preheater. Therefore, the labor intensity is reduced; the production cost is saved; and the safety factor is improved.
Description
Technical field
The utility model relates to a kind of preheater, relates in particular to a kind of preheater of ammonium sulfate workshop section.
Background technology
In ammonium sulfate workshop section, to pass through the gas preheating device from the raw gas of desulfurization workshop section, with getting into multiple saturex after the raw gas preheating.Because entrained oil coke powder in the coal gas causes pipe choking in the preheater, thereby cause the coal gas resistance to increase, blower pressure increases; Therefore preheater needs periodic cleaning, but preheater is an one, need lift dismounting during cleaning; Program is complicated, and labour intensity is big, and coefficient of injury is high.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of sulphur ammonium work preheater is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of ammonium sulfate workshop section preheater comprises preheater, is connected with gas inlet pipe in the bottom of preheater; Be connected with the coal gas vapor pipe on the top of preheater; Bottom at preheater is provided with blow-off pipe, and the upper end of preheater is provided with flange, and end cap is assembled together through flange and preheater.
Above-mentioned ammonium sulfate workshop section preheater is provided with a big discharge capacity valve on the said blow-off pipe.
Adopt technique scheme, the utility model has following advantage: because a flange is installed on preheater, the upper end cover of preheater and preheater just assemble through flange like this; When needing cleaning,, just can clear up preheater easily as long as pull down the end cap of flange upper end; Need not lift the dismounting preheater; Alleviate labour intensity, saved production cost, also strengthened SF simultaneously.
Description of drawings
Fig. 1 is traditional ammonium sulfate workshop section preheater structural representation.
Fig. 2 is the structural representation of the utility model.
