Abstract
The utility model relates to denitrating catalyst field, is a kind of primary drying room steam heat transfer unit (HTU) that denitrating catalyst is used of producing.In the left side of drying shed, be equipped with into jet chimney, seven steam hot channels are housed in the bottom of drying shed, in each steam hot channel, have steam (vapor) outlet, on the top of drying shed, air exhauster is housed, the upper end of heat radiation dehumidifying pipelines is connected with air exhauster, and lower end communicates with drying shed; The air outlet of air exhauster is connected with exhaust dehumidifying pipelines; In exhaust dehumidifying pipelines, Temperature control valve is housed, numerical control thermostat is housed outward, upper end is connected with vapor recycle pipeline.Owing to having adopted the technical program, the steam flow rate that dry catalyst is used slows down, is evenly distributed, and primary drying is effective, and the curved distribution of rate of drying can not cause catalyst thermal stress damaged, and yield rate is high.
Description
Technical field
The utility model relates to denitrating catalyst field, is a kind of primary drying room steam heat transfer unit (HTU) that denitrating catalyst is used of producing.
Background technology
The outlet of the dry steam pipe that original production denitrating catalyst is used is straight, and steam flow rate is very fast, easily causes catalyst thermal stress damaged, causes yield rate low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the primary drying room steam heat transfer unit (HTU) that provides a kind of new production denitrating catalyst to use.
The technical solution of the utility model is: a kind ofly produce the primary drying room steam heat transfer unit (HTU) that denitrating catalyst is used, it is characterized in that being equipped with into jet chimney in the left side of drying shed, seven steam hot channels are housed in the bottom of drying shed, in each steam hot channel, there is steam (vapor) outlet, air exhauster is equipped with on top at drying shed, the upper end of heat radiation dehumidifying pipelines is connected with air exhauster, and lower end communicates with drying shed; The air outlet of air exhauster is connected with exhaust dehumidifying pipelines; In exhaust dehumidifying pipelines, Temperature control valve is housed, numerical control thermostat is housed outward, upper end is connected with vapor recycle pipeline.
Owing to having adopted technique scheme, the steam flow rate that dry catalyst is used slows down, is evenly distributed, and primary drying is effective, and the curved distribution of rate of drying can not cause catalyst thermal stress damaged, and yield rate is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, drying shed; 2, enter jet chimney; 3, steam hot channel; 4, steam (vapor) outlet; 5, exhaust dehumidifying pipelines; 6, heat radiation dehumidifying pipelines; 7, air exhauster; 8, numerical control thermostat; 9, Temperature control valve; 10, vapor recycle pipeline.
The specific embodiment
Below in conjunction with embodiment, the utility model is further described.
In Fig. 1, in the left side of drying shed 1, be equipped with into jet chimney 2, seven steam hot channels 3 are housed in the bottom of drying shed 1,3 li of each steam hot channels have steam (vapor) outlet 4, on the top of drying shed 1, air exhauster 7 is housed, the upper end of heat radiation dehumidifying pipelines 6 is connected with air exhauster 7, and lower end communicates with drying shed 1; The air outlet of air exhauster 7 is connected with exhaust dehumidifying pipelines 5; Temperature control valve 9 is housed in exhaust dehumidifying pipelines 5, numerical control thermostat 8 is housed outward, upper end is connected with vapor recycle pipeline 10.
Enter jet chimney 2 and be connected with drying shed 1 sealing, steam arrives steam hot channel 3 by entering jet chimney 2, then is discharged by steam (vapor) outlet 4, and under the barrier effect of steam water conservancy diversion soaking plate, steam evenly carries out desiccation to catalyst prod appearance.Under air exhauster 7 sucking actions, to in drying shed 1, with steam, by heat radiation dehumidifying pipelines 6, deliver to Temperature control valve 9, under the auto-control effect of numerical control thermostat 8, when vapor (steam) temperature is when more than 50 ℃, Temperature control valve 9 is opened vapor recycle pipeline 10, makes steam get back to heat exchanger and is returned to into jet chimney 2 and recycles; When vapor (steam) temperature is during lower than 50 ℃, Temperature control valve 9 is opened exhaust dehumidifying pipelines 5, by discharge of steam in pond.
