Abstract
The utility model discloses a novel COD online monitor-dehumidification drying device, which is composed of a dehumidification exhaust fan (3), a humidity sensor (4), a temperature controller (5), a heater (6), a dehumidification module control panel (9) as main components, characterized in that: the dehumidification drying device firstly sets the temperature controller (5) to 28 DEG C, the dehumidification module control panel (9) starts working, when the relative humidity (RH) within a tank body (1) reaches 65%, the heater (6) starts heating and stops heating when the temperature within the tank body (1) decreases to 28 DEG C, the dehumidification exhaust fan (3) starts dehumidification and this operation comes to an end after 8 minutes. At this time, the tank body (1) of the monitor includes the temperature from 22 to 25 DEG C and the relative humidity (RH) from 40% to 50%, and the monitor works normally. When the relative humidity (RH) within the tank body (1) reaches 65% once again, the dehumidification module control panel (9) circulates the above procedures so as to constantly maintain the dryness within the tank body (1) of the COD online monitor, as a result, no influence is applied to the monitor in collecting water samples, testing data and sending signals. Using the novel COD online monitor-dehumidification drying device improves poor moisture-proof function of current COD online monitor, and the monitor can work normally in the environment with large humidity and moisture and high relative humidity (RH) for years.
Description
Technical field
The utility model relates to, and (water inlet) or processing back (draining) before city domestic sewage and the urban industry wastewater treatment are to the verification test and the equipment of uploading check data of COD value.Requirement according to the national environmental protection portion and the environmental protection Room, each province: COD on-line monitoring equipment is installed in city domestic sewage and Industrial Wastewater Treatment.With supervision to the COD index.Require: go out one-level A standard or one-level B standard that water quality standard reaches national GB18918-2002, reach China requirement on environmental protection.
Background technology
At present, municipal sewage treatment work is the important step in the environmental protection work, and equipment such as COD on-line monitoring instrument and wireless transmission instrument mainly use, in the machine room at sewage treatment plant inflow mouth and delivery port two places.This two directors year sewage is many, moist, relative air humidity (RH) is big, be at wetness in big season by it; annual 6-8 month; relative humidity in the machine room (RH) can reach more than the 80%-90%; instrument is worked in this environment for a long time; very big to circuit board in the instrument and various electronic devices and components corrosive effects; can often break down: do not show, go out mess code, lose data memory as deadlock, shutdown, liquid crystal display, data such as do not upload at phenomenon.Do not reach good monitoring and upload effect.Along with constantly bringing forth new ideas of technology, I have developed a kind of novel C OD on-line monitoring instrument-dehumidifying drying device, can solve COD on-line monitoring instrument and normally use in wet environment.
Summary of the invention
Technical problem to be solved in the utility model is: solve novel C OD on-line monitoring instrument-dehumidifying drying device, the protection against the tide of equipment in sewage treatment plant inflow mouth and delivery port machine room.In the dehumidifying drying device, install, the dehumidification module control panel, a heater, a humidity sensor and a temperature controller are installed in the bottom in the casing, at the instrument box internal upper part dehumidifying ventilating fan are installed, by dehumidification module control panel and humidity sensor and temperature controller control.
The utility model COD on-line monitoring instrument-dehumidifying drying device, its operation principle is
This instrument partly is made up of casing, LCD, main circuit board, communication connecting plate, Signals Transfer Board, dehumidification module control panel, dehumidifying ventilating fan, humidity sensor, temperature controller, heater etc.The dehumidifying drying device is controlled by the dehumidification module control panel.In working order down, at first the design temperature controller is 28 ℃, and when relative humidity in the casing (RH) when reaching 65%, heater begins heating, in the casing temperature from top to bottom, when reaching 28 ℃, heater stops heating, the dehumidifying ventilating fan begins dehumidifying, dehumidifies 8 minutes, and dehumidifying finishes.Temperature is 22 ℃-25 ℃ in this moment instrument box, and relative humidity (RH) is at 40%-50%, the instrument operate as normal.When the relative humidity in the casing (RH) when reaching 65% again, the dehumidification module control panel above program that circulates so just can remain the aridity in the COD on-line monitoring instrument casing.Make instrument gather water sample, test data, it is unaffected to send signal.
Technical problem to be solved in the utility model is achieved through the following technical solutions
A kind of novel C OD on-line monitoring instrument-dehumidifying drying device is characterized in that:
Described temperature controller is fixed on bottom in the COD on-line monitoring instrument casing, and CARBURIZING FURNACE FOR STAINLESS FASTENER is fixed.
Described humidity sensor is fixed on temperature controller top in the COD on-line monitoring instrument casing, and CARBURIZING FURNACE FOR STAINLESS FASTENER is fixed.
Described heater is fixed on bottom in the COD on-line monitoring instrument casing, and CARBURIZING FURNACE FOR STAINLESS FASTENER is fixed.
Described dehumidifying ventilating fan is fixed on the upper left-hand in the COD on-line monitoring instrument casing, and CARBURIZING FURNACE FOR STAINLESS FASTENER is fixed.
Described dehumidification module control panel is fixed on the back plate face in the COD on-line monitoring instrument casing, and CARBURIZING FURNACE FOR STAINLESS FASTENER is fixed.
The utility model COD on-line monitoring instrument-dehumidifying drying device has the following advantages
A kind of novel C OD on-line monitoring instrument-dehumidifying drying device, this equipment are to be used for the equipment that sewage treatment plant inflow mouth or delivery port machine room use.The use of novel C OD on-line monitoring instrument-dehumidifying drying device, improved the deficiency of existing COD on-line monitoring instrument moisture-proof function, this instrument can be big at throughout the year wet moisture capacity, operate as normal in the high environment of relative humidity (RH), can make the frequent collection water sample of COD on-line monitoring instrument, test data, it is unaffected to transmit signal.
