Description
Technical field
The utility model is related to the waste gas filter in a kind of production of caustic soda.
Background technology
Generally, can produce chlorine contained exhaust gas during production of caustic soda, this chlorine contained exhaust gas must handle after qualified discharge.
A kind of conventional processing mode using the chlorine in sodium hydroxide solution cyclic absorption waste gas, and when absorbing alkali lye preferably with it is useless
Gas counter current contacting.
Traditional emission-control equipment not only complex structure, and the waste gas progress that can not be directed in production of caustic soda is for place
Reason, often can only individually handle organic exhaust gas or sulfide, and treatment effeciency is low and unitary function, it is impossible to meet actually used need
Ask, and in the prior art, in order that spray liquid is uniformly distributed in scrubbing tower, often set many calibers smaller in scrubber overhead
Vertical tube.However, with the progress of cyclic absorption process, the salinity increase in absorbing liquid, it may appear that spray blockage is asked
Topic；In addition, the cleaning solution sprayed from shower is in the form of a column vertical drop, therefore, waste gas can not be contacted fully with cleaning solution, be led
Cause wash mill processing waste gas ability relatively low.
Utility model content
The technical problems to be solved in the utility model, which is to provide one kind, can be such that waste gas is fully contacted with cleaning solution, structure letter
It is single, the waste gas filter that the waste gas in production of caustic soda be directed in the production of caustic soda of processing can be directed to.
To solve the above problems, the utility model is adopted the following technical scheme that：
A kind of waste gas filter in production of caustic soda, to include and be provided with activated carbon above air inlet, the air inlet
Side frames below coarse strainer, the coarse strainer are provided with below granulosa, the air inlet to be provided with installing plate, the coarse strainer
Side middle part is provided with leakage fluid dram, and the activated carbon granule layer top, which is set up, alkali liquor pipe, and the concave shape of alkali liquor pipe is set, described
Alkali liquor pipe is provided with more than one alkali lye shower nozzle, and the alkali liquor pipe the week side of boss is through there is retaining bolt, and the alkali liquor pipe is connected with confession
Liquid pipe, the feed pipe is connected with liquid supply box, and the liquid supply box is located above alkali liquor pipe, and exhaust is additionally provided with above the alkali liquor pipe
Pipe, the alkali lye shower nozzle sets in concave and is densely covered with more than one spray hole.
Preferably, the activated carbon granule layer is set for a plate shape.
Preferably, the activated carbon granule layer is made up of at least three layers charcoal absorption net, and charcoal absorption stratum reticulare
Layer is nested to be set.
Preferably, the alkali lye shower nozzle is evenly distributed.
Preferably, the leakage fluid dram is connected with waste water collection tank.
The beneficial effects of the utility model are：, can be for caustic soda life by the activated carbon granule layer and coarse strainer of setting
The particulate matter that is produced during production carries out processing recovery, meanwhile, be also collocated with the alkali liquor pipe that concave shape is set, and one with
On alkali lye shower nozzle, by increasing capacitance it is possible to increase the contact surface with waste gas, improve filter effect, while be also collocated with special setting alkali lye spray
Head, can further increase the contact area of waste gas and alkali lye, further improve filter effect.
Brief description of the drawings
Fig. 1 be a kind of production of caustic soda of the utility model in waste gas filter overall structure diagram；
Fig. 2 be a kind of production of caustic soda of the utility model in waste gas filter alkali lye nozzle structure schematic diagram.
Embodiment
As shown in Figure 1-2, the waste gas filter in a kind of production of caustic soda, includes on air inlet 1, the air inlet 1
Side is provided with coarse strainer 3 provided with activated carbon granule layer 2, the lower section of air inlet 1, and the lower section side frames of coarse strainer 3 are provided with
Installing plate 4, the lower section of coarse strainer 3 middle part is provided with leakage fluid dram 5, and the top of activated carbon granule layer 2, which is set up, alkali liquor pipe 6, institute
The setting of the concave shape of alkali liquor pipe 6 is stated, the alkali liquor pipe 6 is provided with more than one alkali lye shower nozzle 7, and the week side of boss of alkali liquor pipe 6 is passed through
Retaining bolt 8 is installed with, the alkali liquor pipe 6 is connected with feed pipe 9, and the feed pipe 9 is connected with liquid supply box 10, and the liquid supply box 10 is located at
The top of alkali liquor pipe 6, the top of alkali liquor pipe 6 is additionally provided with blast pipe 11, and the alkali lye shower nozzle 7 sets and is densely covered with concave
More than one spray hole 12.
The activated carbon granule layer 2 is that a plate shape is set, and can carry out pull, be conveniently replaceable.
The activated carbon granule layer 2 is made up of at least three layers charcoal absorption net, and charcoal absorption stratum reticulare layer nesting is set
Put, filter effect is more preferably.
The alkali lye shower nozzle 7 is evenly distributed, and also can according to circumstances adjust.
The leakage fluid dram 5 is connected with waste water collection tank 13, Recycling of waste liquid.
When in use, waste gas is passed through waste gas filter by air inlet 1, and gas is via the first of activated carbon granule layer 2
