Zdhw-8a automatic calorimeter, coal detection instrument
Product introduction:
Model zdhw-8a intelligent calorimeter is directly sold by Hebi Keda factory, which is a special calorimeter for coking plant. The calorimeter adopts unique heat insulation design, and the temperature change of outer barrel after each test is less than 0.1 ℃. It takes the lead to apply siphon principle to water level balance, and has automatic water injection, drainage, ignition, automatic data processing and analysis, and printing results, which is convenient to use and has high reliability.
Scope of application:
Zdhw-8a intelligent calorimeter is a Chinese character display intelligent calorimeter for measuring the calorific value of combustible materials, which conforms to the requirements of constant temperature calorimeter method in GB / t213-2008 "determination method of calorific value of coal". The instrument is mainly used for solid and liquid combustible materials, especially for coking plant, coal, petroleum, electric heating company, electric power plant, coal washing plant, geology, building materials, chemical industry, energy saving, papermaking, petrochemical, cement, agriculture and animal husbandry, scientific research, teaching, steel, feed, paper making, chemical industry, cement, brick making, teaching, scientific research and other units.
Technical parameters:
Precision of heat capacity: ≤ 0.1%
Test time: 15 ~ 18min
Temperature resolution: 0.0001 ℃
Power supply voltage: 220 V ± 10% 50 Hz
Host size: 600 × 460 × 520
Weight: 31kg
Functional features:
1. Automatic water injection, drainage, mixing, ignition, data acquisition and processing, data storage, display instrument status, automatic printing test results.
2. 50L large capacity water tank ensures that the temperature change of outer barrel is less than 0.1 ℃ after each test
3. The unique heat insulation design reduces the temperature and heat exchange rate between the main barrel and the outside and inside the barrel.
4. The water level automatic balance device of inner barrel can ensure the consistency of water volume of inner barrel in each experiment.
5. The siphon principle is first applied to the water level balance to solve the problem of inaccurate positioning of water level probe, and ensure the long-term stability of its thermal capacity and meet the requirements of national standards
6. Single chip microcomputer control system, high reliability, not affected by computer viruses.
Main structure of calorimeter
The main engine of calorimeter is mainly composed of shell, outer cylinder, inner cylinder, agitator, oxygen bomb, etc.
(1) The outer shell is made of high-quality plastic coated steel plate.
(2) The heat measuring outer cylinder is a double-layer sleeve made of stainless steel. The circulating water pump can adjust the water temperature evenly. There are water inlet, water outlet and overflow port on the cylinder wall, which is convenient for adjusting the water temperature and water level.
(3) The inner cylinder is a stainless steel vessel with oval cross section, and its surface is polished to reduce heat radiation and heat exchange.
(4) The agitator is composed of a micro motor, a mixing shaft and a slurry, which is fixed on the cover body.
(5) The oxygen bomb is made of special stainless steel. It is qualified after 20MPa water pressure inspection.
accessory equipment
The oxygen charging device is a special supporting device for oxygen bomb.
Working principle: the oxygen in the oxygen bottle is fed into the charging valve through the oxygen pressure reducer, and the valve plug in the valve closes the oxygen charging valve with the help of oxygen pressure. During oxygen charging, put the oxygen bomb, press the handle, and the valve plug is pushed open by the oxygen bomb to charge oxygen into the oxygen bomb. The oxygen charging pressure is indicated by the oxygen pressure gauge.
Daily maintenance and inspection
The following inspection and maintenance should be carried out frequently after the experiment every day, which can keep the instrument in good working condition and prolong its service life.
1. Oxygen bomb: in addition to cleaning and drying the oxygen bomb after each test, the following points should also be noted and checked:
(1) The oxygen bomb can only be turned by hand. It should be stopped when the handle is tightened. Do not use tools to screw hard. After the test is finished every day, clean it once.
(2) The spring cap and valve seat should be washed and dried after use.
(3) Clean the spring cup, wipe the thread, and check the upper part of the spring cup for mechanical damage.
(4) Check whether the seal ring is worn. If the seal is not tight and there is air leakage, it should be replaced.
(5) Check whether the insulation of two-point fire electrodes is good, and regularly check the insulation performance.
(6) Water pressure test of 20MPa shall be carried out on oxygen bomb regularly. After each hydraulic test, the service life of oxygen bomb shall not exceed two years.
2. Keep the inside of the water tank dry for a long time

Calibration calorimeter
After cooling to room temperature, place the benzoic acid in the middle of the standard oxygen bomb for more than 10.3ml, and then put it into the oven for drying. After that, put it on the oxygen bomb and keep it at the temperature of 0.3ml Select the heat capacity of the instrument
Enter the interface and switch to heat capacity test. Input benzoic acid weight, benzoic acid calorific value and ignition wire calorific value. After 10 minutes, the instrument was ignited, and 20 minutes later, the experiment was finished. The E (heat capacity) value, K (cooling constant) value and a (Comprehensive constant) value were calculated. After five consecutive samples were made, the average value was calculated five times, and the calibration was completed.
