(54) IMPROVEMENTS IN OR RELATING TO METHODS AND
APPARATUS FOR HEAT RECOVERY
(71) I, JOHN BERNARD PETER
BARNES a British Subject of Hunter’s Cottage, Billingshurst Road, Ashington, Sussex do hereby declare the invention for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following sartement:– This invention relates to methods and apparatus for heat recovery.
The main object of the present invention is the recovery of heat by a continuous thenno- philic composting process from vegetable materials that are disposed of during normal cropping cycles for example in the horticultural industry.
According to the invention the method of heat recovery comprises feeding vegetable matter into the upper end of a stack of such matter, removing decomposed matter from the lower part of the stack, blowing air directly into the interior of the stack, removing heat frtm the interior of the stack by means of a heat transfer fluid flowing through the stack but isolated from said matter, and utilising the fluid for heating a structure outside the stack.
Also according to the invention apparatus for effecting heat recovery comprises a bin having inlet means at its upper end suitable for introduction of vegetable matter, outlet means at its lower end suitable for removal
of decomposed vegetable matter, means for blowing air directly into the interior of the vegetable matter in the bin, ducting in the
space which will contain the vegetable matter
to receive heat from the decomposing matter
and inlet and outlet connections to the ducting
for cofd the ducting to a structure
located outside the bin. The fluid (e.g. water)
is pumped thorough the ducting and the
heated outgoing fluid is utilised for heating
where required e.g. for heating glasshouses,
mushroom copping houses and other
structures.
The air serves to aid decomposition of the
vegetable matter and may be supplied in the container with an added activator such as effluent or liquid manure.
When the vegetable material is sufficiently decomposed it may be used as a humus for growing corps. The decomposed vegetable material may be removed from the bottom of the stack and fresh vegetable material added to the top of the stack from time to time, e.g. daily or at intervals up to once a week.
This will vary with the materials being used and the rate of decomposition, a balance being established between the various waste components in each individual case.
The invention will be further described by way of example with reference to the accompanying diagrammatic drawings wherein: FIGURE 1 is a vertical sectional view of one form of an apparatus made in accordance with the invention; and FIGURES 2 to 5 show various modifications and uses of the invention.
A bin 10 may be similar to a corn storage bin. It may be made of galvanised iron, aluminium sheeting or may be brick built. It may be circular or other shape in plan. The bin is mounted on a concrete base 9. The outer wall of the bin can be well insulated or of cavity construction with the insulation on the exterior wall.
Located centrally in the bin is a veritcal air channel 12 connected at its lower end to an inlet 13 which extends outside of the bin and is fed wiht air from a blower or fan 14 thereby providing oxygen which is utilised by the bacteria in the compost and any additional supply of which will produce increased bacterial activity and therefore more heat. The upper end of the channel 12 has a cap 16 located a short distance above it which directs the air for extraction, or a damper for a re-carculation of a part of the air. The channel 12 is perforated. Air supplied to the channel 12 can be used for controlling the temperature of the compost. The fan can be controlled by a thermostat inserted in the compost, or by sensing the outgoing water temperature.
Switching of the fan on/off will control the microbial activity and thereby the temperature of the compost. A damper control can vary the amount of recirculated air.
The top 17 of the bin has an insulated lid 18 which can be opened to admit entry of the vegetable material.
Around the inner periphery of the walls of the bin a pipe 20 of plastics material or metal construction is wound spirally e.g.
500 ft. of one inch diameter pipe. The upper end of the pipe is connected to an inlet pipe 22 located outside the bin and the lower end is connected to an outlet pipe 23 also located outside the bin.
A spray pipe 25 is mounted in the upper part of the bin and is connected by a pipe 26 to a pump 27 which draws water and the addition of an activator material from a tank 28 if required. A sensor in the upper layers of the compost can activate the pump to cut out when the compost reaches a desired moisture content.
A drain 30 is provided in the conical base of the bin.
The base of the bin has an outlet which may be fitted with a screw conveyor or auger 31 for removing the vegetable material.
Thermometers may be mounted on the walls of the bin to measure the temperature at different positions within the bin.
The pipes 22, 23 are connected to a water supply system circulated by a variable speed electric water pump. The pipes 22, 23 are also connected with any suitable hot water heating system for heating a glasshouse, mush- room house, domestic system, swimming pool, or other required system.
In the modification shown in Figure 2 the ducting 20 is in the form of vertical pipes of which any suitable number may be provided at the same or various diameters and connected by upper and lower headers 30, 29.
The air conduit 12-has a return pipe 32 to the
fan 14 and a shut off damper 33 so that when
the damper is open heated air will be re circulated through 12, 32. The bin stands on
legs 35 which may be tall enough to enable a lorry to stand beneath the outlet 31.
FIGURE 3 shows the bin 10 having the pipes connected into the return pipe 40 for
heating fluid between a normal boiler 41 and
a structure heating system 42. The pipe 23 is
connected to the pipe 40 via a pump 43 and
a valve 45 is provided in the pipe 40. A thennostat 44 operates in accordance with the temperature of the water coming from the
pipe 23 and controls the pump 43 and by-pass
valve 45 so that the system 42 is heated by the boiler or the heat fnxn the bin 10 according
to the measurement of temperature. In one
position of the valve 45 fluid circulates around
the pipes 23 without entering pipes 40. In
other positions of the valve 45 the fluid circulates from the pipes 23 partly or wholly through the pipes 40 and back to the pipes
23.Alternatively the thermostat 44 may be
in the system 42 or in the structure heated
by the system (e.g. the air temperature in a
glasshouse).
FIGURE 4 shows an arrangement in which
a double skin 50, 51 is separated by webs 52
forming channels. This arrangement can be
used for the walls of the bin and/or for the
walls of the pipes 22, 23.
FIGURE 5 shows a modification in which
a number of vertical air conduits 60 are pro
vided and fed by the fan 14. The pipes 22,
23 are connected to the heating system of a
glasshouse 61.
