Description
Technical field
The utility model relates to the heat treatment technics field of wood package materials.
Background technology
The wood package materials of the statutory regulations imported goods of many country promulgations must adopt methods such as heat treatment, and provide certificate by animal and plant quarantine department of official of exporting country in exporting country's disinfection of quarantining before shipment, just allows goods to leave the country.In March, 2002 FAO (Food and Agriculture Organization of the United Nation) and IPPC Secretariat approval and " plant quarantine measure international standard " the approval heat treatment (HT) of announcing are one of quarantine disinfection method of Wooden package.
At present, the approval of China entry and exit inspection and quarantine bureau also drops into the Wooden package heat treatment facility of actual production, classifies according to its heat-conduction medium, can be divided into three types of steam heatings, hot dry wind heat supply, conduction oil heat supply.
Steam heating need be acquired steam boiler and boiler room building, and initial stage equipment input is very big, the construction cost costliness, energy consumption is big, and need to consume big water gaging, maintenance and maintenance cost are also higher, must change parts such as SRZ type flight radiator, injection spray pipe and drain pipe per one or two years.
The hot dry wind heat supply is handled, its principle is to be communicated with thermal chamber and to heat being located at steel pipe in the burner hearth, the xeothermic inner air tube that is produced after steel pipe in the burner hearth is heated, be transported in the thermal chamber by centrifugal blower, simultaneously, the normal pressure kettle is set above burner hearth, and the steam of generation is used for regulating humidity.Belong to combustion product from fuel combustion, heat transfer angle and pass through steel pipe and the indirect room air, the thermal efficiency is low.Disadvantage is: constant temperature and humidity is handled can't realize automatic control; The indoor temperature uniformity is relatively poor; Often the maintenance steel pipe enters xeothermic air channel to avoid stove cigarette, ashes, Mars and the pipe damage and crack of imperfect combustion material invar.
The conduction oil heat supply is handled, and its principle is to adopt the conduction oil heat supply.Use corrosion resistant plate and the some seamless steel pipes airtight boiler that is welded, splendid attire conduction oil in the boiler, boiler places on the burner hearth, all kinds of fuel combustions produce thermal source, heat-conducting oil heating in the boiler is heated up, by transferring oil steel pipe (sending oil pipe) and withdrawing oil steel pipe (oil return pipe) the outer heat-conducting oil furnace of thermal chamber is connected with radiator in the thermal chamber, constitute circulating oil path, and the heat resisting motor oil pump of in sending oil pipe, connecting, by forced circulation the conduction oil through heat temperature raising in the heat-conducting oil furnace is sent in the thermal chamber, be back to heat-conducting oil furnace through behind the radiator, thereby realize heat temperature raising the heat treatment room air; The axial flow circulating fan is installed, to accelerate the heat exchange of radiator and room air at the radiator rear.
Above-mentioned three kinds of heat-supplying modes all belong to or heat medium or combustion product heat furnace air by radiator, belong to the indirect mode, compare with air in the combustion product directly-fired kiln, and the thermal efficiency is low; The configuration of radiator has increased input expense and Maintenance and Repair expense.
