Technical field
The present invention relates to the moisture control system of a kind of denitrating catalyst primary drying operation, belong to denitrating catalyst and produce
Technical field of auxiliary equipment.
Background technology
Along with the national economic development, population increase and the quickening of urbanization process, problem of environmental pollution highlights day by day, especially
It is SO2And NOXEmission problem.NOXThe environmental problems such as acid rain, photochemical fog, surface water eutrophication, and energy can be caused
Enough endanger human health, therefore take safeguard procedures very urgent for it.The technology that denitration efficiency is the highest, the most ripe at present
Being SCR (SCR) technology, this technology relies on the active component in catalyst by NOxCatalysis is reduced to free of contamination
N2, thus reach to purify the purpose of air.
In prior art, SCR denitration is in preparation process, needs, through dry, calcine technology, then to obtain honeybee
The catalyst prod of nest structure, wherein drying process be divided into once, redrying, in primary drying operation, in hothouse
Temperature and humidity have higher requirements, and in prior art, in order to reach the metastable purpose of hothouse humidity, generally adopt
By the method being passed through steam, and being passed through of steam can directly result in dry indoor temperature and rise, thus in causing hothouse
The problem that the accurate controlling of ambient parameter is poor, in prior art, this problem is difficult to well solve, to a certain extent all the time
Limit the stability of primary drying technique.
Summary of the invention
For solving problems of the prior art, the invention provides the wet of a kind of denitrating catalyst primary drying operation
Degree control system, concrete technical scheme is as follows:
The moisture control system of a kind of denitrating catalyst primary drying operation, including hothouse, described hothouse is provided with and adds
Wet system, described humidification system includes successively according to air-flow direction: stretch into the suction opeing of hothouse, air exhauster, heat exchange
Device and the ajutage stretching into hothouse, be provided with ultrasonic humidifying generator between described air exhauster and heat exchanger.
As the improvement of technique scheme, described ajutage end humidifies pipeline with " L " shape in hothouse and is connected, institute
State humidification pipeline bottom even and offer multiple air-vent.
As the improvement of technique scheme, between described ultrasonic humidifying generator and ajutage, it is provided with isocon
Road.
Improvement as technique scheme, it is characterised in that be provided with external heat-exchanging pipeline on described heat exchanger.
As the improvement of technique scheme, described hothouse is also associated with dehumidifying pipeline.
This technical scheme of technique scheme joins in hothouse by using ultrasonic humidifying generator to produce steam,
Effectively avoid the problem that the dry indoor temperature using steam humidification to cause in prior art rises, and heat exchanger
Existence can control the temperature of air in humidification system in real time, thus the regulation of temperature, humidity is united two into one, decreases and set
Standby input, regulative mode more simple and fast, beneficial effect is notable.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the invention provides the moisture control system of a kind of denitrating catalyst primary drying operation, bag
Including hothouse 10, described hothouse 10 is provided with humidification system, described humidification system includes successively according to air-flow direction:
Stretch into the suction opeing 20 of hothouse 10, air exhauster 21, heat exchanger 22 and stretch into the ajutage 23 of hothouse 10, described air exhauster
Ultrasonic humidifying generator 30 it is provided with between 21 and heat exchanger 22.This technical scheme is by using ultrasonic humidifying generator
30 produce steam joins in hothouse 10, effectively avoids and uses steam to humidify the hothouse 10 caused in prior art
The problem that interior temperature rises, and the existence of heat exchanger 22 can control the temperature of air in humidification system in real time, thus will
Temperature, the regulation of humidity unite two into one, and decrease equipment investment, regulative mode more simple and fast.
Further, as shown in Figure 3, Figure 4, described ajutage 23 end and " L " shape humidification pipeline 24 in hothouse 10
Connecting, described humidification pipeline 24 bottom even offers multiple air-vent 241, and ultrasonic humidifying can be sent out by this humidification pipeline 24
The steam that raw device 30 produces is sent in hothouse 10, and air-vent 241 is each region humidity in then may insure that hothouse 10
Concordance.
Further, between described ultrasonic humidifying generator 30 and ajutage 23, it is provided with shunt conduit 25, due to
General primary drying operation generally has many group hothouses 10 and is arranged in juxtaposition, and the effect of this shunt conduit 25 is to be added by ultrasound wave
The steam that wet generator 30 produces is delivered in other adjacent hothouses 10.
In the above-described embodiments, described heat exchanger 22 is provided with external heat-exchanging pipeline 40, this external heat-exchanging pipeline 40,
This external heat-exchanging pipeline 40 uses the high-temperature-hot-water of electrically heated 90 DEG C～95 DEG C of low ebb as the sky in heating agent, with humidification system
Gas carries out heat exchange, and the air in humidification system is heated to the technological temperature that hothouse 10 needs, and this technological temperature is typically 40
DEG C～65 DEG C between, before being arranged in heat exchanger 22 due to ultrasonic humidifying generator 30, heat exchanger 22 operationally may be used
Heat with steam hot-air and ultrasonic humidifying generator 30 produced simultaneously, it is ensured that the temperature in hothouse 10 will not
Affected by humidity regulation.
Further, described hothouse 10 being also associated with dehumidifying pipeline 50, the effect of this dehumidifying pipeline 50 is to be dried
When room 10 humidity is higher, the air in hothouse 10 is discharged a part, and reduces the steam of ultrasonic humidifying generator 30
Generating capacity, thus regulation is dried 10 humidity to normal range.
Above embodiments of the invention are described in detail, but described content have been only presently preferred embodiments of the present invention,
Being not to be regarded as the practical range for limiting the present invention, all equalizations made according to the scope of the invention change and improvement etc., all should
Within still belonging to covering scope of the present invention.
