One, overview
GTLC series drum slag cooling machine is improved in GTL seriesdrum slag cooler on the basis of the original, is to adapt to thecirculating fluidized bed boiler direction to the development of large capacity requirements of the design and development. It consists ofshutter type heat transfer drum, slag feeding device, a slag device,a rotating mechanism, cooling water system and electric controldevice. For fluidized bed and fluidized bed boiler slag cooling.
Two, institutional characteristics
1, the unique tubular structure, abrasion resistance, long service life;
2, a good solution to the stress concentration, no leakage;
3, star swing reducer + chain transmission structure of the rolleraccurate transmission, stable;
4, the bidirectional rotary joint, is convenient maintenance, safety;
5, a super pressure, temperature, water and automatic alarm andsafety protection device;
6, a high degree of automation, greatly reducing the amount of labor;
7, slag containing a large space, strong adaptability;
8, no strict quality requirements, can use soft water, also can use ≤ 55 ° industrial circulation water;
9, cold slag machine follow-up equipment installation, convenient arrangement;
10, there is air cooled as auxiliary cooling way, not only reduce theequipment water consumption, but also reduce the site dustphenomenon;
11, cold slag machine inlet end and sealed with the most advanced"slag leakage proof structure" technology;
12, cold slag machine adopts "synchronous regulating wheel structure", the roller with adjustable height;
13, high heat transfer efficiency, discharge temperature adaptationrange (40 ℃ --220 ℃);
14, frequency control to realize automatic tracking boiler slag quantity output.
Three, the main technical parameters
The specific type cold slag machine is: GTLC---n x L left (or right).wher n is the output (t/h), L is the import and export of distance(mm), the left represents the left, right represents the right type.
According to the drive motor position (see Figure 1) to distinguish,cold slag machine has left and right type; in the face of slag cooleroutlet, motor in the left to right and left, on the right type.
The cooling medium in water, water pressure is not more than 0.6Mpa, the most appropriate water softening (allows the water temperature up to 90 C). If the general industrial water, shouldcontrol water temperature less than 60 degrees, the watertemperature is high, should be regularly.
Cooling water consumption per ton of slag cooling water: W withimport slag temperature (T1-T2), inlet and outlet water temperature difference (t2-t1) changes and the corresponding increase or decrease. According to the following formula:
W=0.24 (T1-T2) / (t2-t1). The unit M3 water /t slag
Air cooled tube DN200 is usually connected to the reactor entranceelectric dust, can maintain the negative pressure cylinder, preventdust overflow pollution of the environment.
Boiler slag discharging tube can be directly inserted into the cold slag machine hopper, the gap with high temperature resistant glass fiber or asbestos cord plugged.
Cold slag machine length usually and output, slag temperature and the bottom of the layout space. If no special requirements, such asthe length of the data shown in the table below.
Four, installation instructions
Not less than 600Kgf/m2 capacity of cold slag machine placed flat on the ground, without bolt, only a pre ground slag cooler base fourcorner buried iron, and other cold slag machine is in place in the pre buried steel welding to prevent iron block horizontal movement.
When the above ground installation, can be in above groundpouring two longitudinal, strip foundation or four horizontal C30 concrete.
When the two type cold slag machine side by side close to thelayout, for ease of maintenance and debugging, should make its drive motor on the outside, namely the left type cold slag machineplaced on the left, on the right side of the cold slag machine placed in the right.
Five, other
